    Torque-angle relationship are better preserved during eccentric compared to concentric contractions in patients with stroke2012In: Isokinetics and exercise science, ISSN 0959-3020, E-ISSN 1878-5913, Vol. 20, no 2, p. 129-140Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to compare the effect of isokinetic contraction mode and velocity on the torque-angle relationship during maximum voluntary elbow flexion in patients with stroke, age-matched healthy subjects and young subjects. To eliminate the effect of torque amplitude differences between subjects and groups, the torque values throughout the ROM were individually normalized to the peak value for each contraction velocity. The results show that in stroke patients the normalized torque angle relationship during the eccentric contractions was better preserved than during concentric contractions. Specifically, during eccentric contractions, stroke patients exhibited a torque-angle relationship that was closer to normal as the test velocity increased. The opposite trend could be seen in concentric contractions where the torque-angle relationship became more divergent from normal with a rise in the velocity. The torque-angle relationships were essentially the same for the control groups, irrespective of contraction mode or velocity. These findings may have significance for loading patterns of resistance training exercises used with stroke patients as such exercises normally are biomechanically designed for normal torque angle relationships. In clinical practice, these findings may partly explain why the strength increases due to resistance training are limited for patients with stroke.

    Test-retest och interbedömarreliabilitetav tre fysiska tester för militärtjänsten2013Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [sv]

    Bakgrund: Reliabla testmetoder behövs för att mäta fysisk prestationsförmåga vid rekrytering och uppföljning av personer i militärtjänst. Olika fysiska testbatterier används i länder med väpnade styrkor, men bara ett fåtal av de är uvärderade för reliabilitet. Det svenska försvaret har utvecklat ett nytt testbatteri innehållande sex fysiska tester. Valet av dessa är grundat på de operativa kraven. Syftet med denna studie har varit att bedöma test-retest och interbedömarreliabiliteten av testerna, Dips, Sidoplankan och Ranger test.

    Metod: Totalt 43 friska, aktiva, tjänstgörande militärer vid Göta regemente i Eksjö, ålder 19-46, genomförde alla tester. För att bedöma test-retest testades deltagarna vid två tillfällen, separerade av sju dagar, av en bedömare. Inter-bedömarreliabilitet bedömdes vid det andra testtillfället med fyra bedömare. Test-retest och inter-bedömarreliabilitet analyserades med hjälp av intra-klass korrelationskoefficienten (ICC), standard error of measurement (SEM) och smallest real difference (SRD).

    Resultat: Föreliggande studie visade utmärkta ICC-värden (0,992 till 1,0) för inter-bedömarreliabilitet. Test-retest visade goda till utmärkta ICC-värden (0,713-0,963). SEM% värdet vid test-retest var för Dips (12.6%), för Sidoplankan (17.2%) och Ranger test (22.2%).

    Slutsats: Studien visade att Dips, Sidoplankan och Ranger test är reliabla test för att mäta soldaters fysiska prestationsförmåga. Resultaten från studien kan ge värdefull information för forskare och kliniker som vill bedöma fysisk prestation även i andra sammanhang.

    Muskuloskeletala besvär, upplevdhälsa och krav/kontroll hos Load Haul Dump-förare i malmgruva.2013Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion:

    Syftet var att undersöka förekomst av muskuloskeletala besvär, hälsa, upplevd krav/kontroll i arbetet och upplevelse av förarmiljö hos Load Haul Dump-förare, samt undersöka skillnader mellan de som kör el- respektive dieseldriven Load Haul Dump-maskin.

    Metod:Ett kvantitativt frågeformulär rörande förekomst av muskuloskeletala besvär (Nordic Musculosceletal Questionnaire - NMQ), hälsa, krav/kontroll (Demand Control Questionnaire - DCQ) och förarmiljö besvarades av LHD-förarna. 104 (12 kvinnor, 90 män, 2 uppgav ej kön) av totalt 138 raslastare deltog i studien. Bortfallet var 25 %.Resultat:79 % hade upplevt muskuloskeletala besvär senaste året. Nacke, ländrygg och skuldra/axel var vanligaste besvärsområdena. Besvärsfrekvensen var högre hos de som körde dieseldriven maskin. 79,6 % upplevde hälsan som god. Endast 27,7 % upplevde högra krav och låg kontroll i arbetet.

    Konklusion:Hög besvärsförekomsten kan ha orsakats av helkroppsvibrationer kombinerat med ogynnsamma kroppsställningar, maskinens skick samt förarstolens inställningsmöjligheter. Dieselmaskinens stol hade mindre rotation och stolinställning samt maskinskick upplevdes i högre grad som sämre, vilket kan vara en anledning till att dieselförarna uppgett mer besvär. Maskinens skick och utformning har stor betydelse varför fortsatta ergonomiska interventioner är viktiga.

    How to adapt the pulmonary rehabilitation programme to patients with chronic respiratory disease other than COPD2013In: European Respiratory Review, ISSN 0905-9180, E-ISSN 1600-0617, Vol. 22, no 130, p. 577-586Article in journal (Refereed)
    Abstract [en]

    Dyspnoea, fatigue, reduced exercise tolerance, peripheral muscle dysfunction and mood disorders are common features of many chronic respiratory disorders. Pulmonary rehabilitation successfully treats these manifestations in chronic obstructive pulmonary disease (COPD) and emerging evidence suggests that these benefits could be extended to other chronic respiratory conditions, although adaptations to the standard programme format may be required. Whilst the benefits of exercise training are well established in asthma, pulmonary rehabilitation can also provide evidence-based interventions including breathing techniques and self-management training. In interstitial lung disease, a small number of trials show improved exercise capacity, symptoms and quality of life following pulmonary rehabilitation, which is a positive development for patients who may have few treatment options. In pulmonary arterial hypertension, exercise training is safe and effective if patients are stable on medical therapy and close supervision is provided. Pulmonary rehabilitation for bronchiectasis, including exercise training and airway clearance techniques, improves exercise capacity and quality of life. In nonsmall cell lung cancer, a comprehensive interdisciplinary approach is required to ensure the success of pulmonary rehabilitation following surgery. Pulmonary rehabilitation programmes provide important and underutilised opportunities to improve the integrated care of people with chronic respiratory disorders other than COPD.

    Motivationsekvationen: att vägleda äldre personer till fysisk aktivitet2008In: Fysioterapi, no 5, p. 38-45Article in journal (Other academic)
    Abstract [sv]

    Det finns ett tydligt samband mellan ökad ålder och minskande fysisk aktivitet, trots att aktiviteten ger hälsovinster för äldre personer på alla funktionsnivåer. Många äldre har kontakt med hälso- och sjukvården, vilket ger personalen en ypperlig möjlighet att påverka dem. För att vägleda äldre personer till fysisk aktivitet gäller det att finna faktorer som ökar motivationen och att identifiera barriärer. Motivationsekvationen, som presenteras här, är en modell som belyser sambandet mellan fyra faktorer: ”upplevd chans att lyckas” och ”upplevd betydelse av målet” i förhållande till ”upplevd kostnad” och ”benägenhet att bli stillasittande”. Samspelet mellan dem styr våra medvetna och omedvetna val när det gäller att påbörja och bibehålla olika beteenden. Faktorerna kan påverkas, direkt eller indirekt, och genom att öka de båda förstnämnda och minska de båda senare skapas hög motivation. Motivationsekvationen kan användas för att kartlägga patientens motivationsnivå. Tillsammans med det vägledande samtalet ger den möjlighet till individuellt skräddarsydda åtgärder.

    Getting up when falling down: reducing fall risk factors after stroke through an exercise program2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The purpose of this thesis was to identify fall risk individuals (+55) after stroke by validating a fall risk index and in post-stroke individuals with high risk of falls evaluate the impact of an intervention program on fall risk factors.A previously developed fall risk index was validated, modified and re-validated. The validation showed a sensitivity of 97% and a specificity of 26%. This result was not considered sufficiently accurate. Therefore a modified index was created in the Validation sample and re-validated back in the Model fit sample. The modified index was reduced to three items and included postural stability + visuospatial hemi-inattention + male sex.The randomized controlled trial contained an intervention program (IP) with High-Intensity Functional Exercises as well as implementation these exercises in to real life situations together with educational group discussions. The participants were enrolled and randomized three to six months after their stroke. The assessments were performed at the Clinical Research Center at Norrlands University Hospital. The Intervention Group (IG) received a program of 35 sessions (exercise and group discussions) and the Control Group (CG) received five group discussions.Performing daily activities at 6 months follow-up and falls-efficacy post-intervention and at the 3 months follow-up showed significant improvement in the IG compared with the CG (p<0.05). The IP did not have a statistically significant impact on Balance or Lifestyle activities. When evaluating gait, step time variability for the paretic leg and the variability in Cycle Time for the paretic and non-paretic leg were improved for the IG. The time spent on the non –paretic leg in the gait cycles’ most stable phase, Double Support, was reduced by almost half (0.9 sec to 0.4 sec) since baseline for the IG after the intervention and remained reduced to the three month follow-up. Quality of Life showed an improvement in the CG compared with the IG for the mental scales, Mental Component Scale and Mental Health subscale at the 3 month follow-up (p=.02).In conclusion, this intervention program significantly improved performance of everyday life activities, falls-efficacy and the variability in gait. These are three major fall risk factors and might in the long run have an impact on decreasing falls in persons that had a stroke.

    What is the benefit of a high intensive exercise program?: A randomized controlled trial2010In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 12, no 3, p. 115-124Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to evaluate a high intensive exercise program in stroke subjects with risk of falls regarding balance, activities of daily life, falls efficacy, number of falls and lifestyle activities. The intervention program contained high intensity functional exercises (HIFE) implemented to real-life situations together with education on falls and security aspects. This was a single-center, single-blinded, randomized controlled trial. Consecutive >55-year-old patients with risk of falls were enrolled and randomized 3–6 months after first or recurrent stroke to the intervention group (IG, n=15) or to the control group (CG, n=19) who received group discussions about hidden dysfunctions after stroke. Outcomes were Berg Balance Scale (BBS) primarily, Barthel Index (BI), Falls Efficacy Scale – International (FES-I) and number of falls secondarily and Frenchay Activities Index last 3 months (FAI-3) tertially. Assessments were done at baseline, post-intervention, 3- and 6-month follow-up by two physiotherapists and one nurse blinded to group allocation. Generalized Estimating Equations with Repeated-measure statistics were used to analyze the data. There were no significant differences between the IG and the CG regarding balance (BBS). BI at 6 months and FES-I post-intervention and 3 months follow-up showed significant improvement in the IG compared with the CG (p<0.05). Number of falls and FAI-3 were without significant change. This study suggests that our program consisting of HIFE implemented in real-life situations together with educational discussions may improve performance of everyday life activities and improve falls efficacy in stroke subjects with risk of falls.

    What is the benefit of a high intensive exercise program on health-related quality of life and depression after stroke?: A randomized controlled trial2010In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 12, no 3, p. 125-133Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to evaluate the impact of a high-intensive exercise program containing high-intensive functional exercises implemented to real-life situations together with group discussions on falls and security aspects in stroke subjects with risk of falls. This was a pre-specified secondary outcome for this study. For evaluation, Short Form-36 (SF-36) health-related quality of life (HRQoL) and the Geriatric Depression Scale-15 (GDS-15) were used. This was a single-center, single-blinded, randomized, controlled trial. Consecutive ≥55 years old stroke patients with risk of falls at 3–6 months after first or recurrent stroke were randomized to the intervention group (IG, n=15) or to the control group (CG, n=19) who received group discussion with focus on hidden dysfunctions but no physical fitness training. The 5-week high-intensive exercise program was related to an improvement in the CG in the SF-36 Mental Component Scale and the Mental Health subscale at 3 months follow-up compared with baseline values while no improvement was seen in the IG at this time. For the SF-36 Physical Component Scale, there was an improvement in the whole study group at 3 and 6 months follow-up compared with baseline values without any significant changes between the IG and CG. The GDS-15 was unchanged throughout the follow-up period for both groups. Based on these data, it is concluded that high-intensive functional exercises implemented in real-life situations should also include education on hidden dysfunctions after stroke instead of solely focus on falls and safety aspects to have a favorable impact on HRQoL.

    The impact of an high intensive exercise program on gait after stroke: a randomized controlled trialManuscript (preprint) (Other academic)
    Abstract [en]

    Stroke often results in asymmetric gait with disturbed balance, which may increase the risk of accidental falls.

    The purpose of this study was to evaluate the impact of a high intensive exercise program after stroke on gait. 34 post-stroke individuals with risk of falls were included in the five week randomized controlled trial. The participants were assessed, included and randomized to the intervention group (IG) or control group (CG) at 3 to 6 months after stroke onset. The IG received a high intensive strength and balance exercise program along with a weekly educational group discussion on fall risk and security aspects, whereas the CG received weekly group discussions on hidden dysfunctions after stroke. Assessments were made before, post-intervention and at 3-months follow-up. Statistically significant (p<0.05) improvements were seen in the IG vs. the CG at post intervention compared with baseline in double support time for the non-paretic leg (DSTnp), variability (measured as coefficient of variation, CV) in Step Time for the paretic leg (STCVp) and the non-paretic leg (STCVnp), and in variability in Cycle Time for the paretic (CTCVp) and non-paretic leg (CTCVnp); at 3-months follow-up compared with baseline in DSTnp, STCVp, CTCVp and CTCVnp, and DSTCVp. At 3-months follow-up, the decrease in the STCVnp and the variability in Step Length of the non-paretic leg (SLCVnp) were more pronounced in the CG than in the IG.

    The findings suggest that high intensive exercise programs have a positive effect on gait, and can be useful in diminishing gait asymmetry as a fall-risk factor in people after stroke.

    Inter-examiner reliability of four static palpation tests used for assessing pelvic dysfunction2008In: Manual Therapy, ISSN 1356-689X, E-ISSN 1532-2769, Vol. 13, no 1, p. 50-56Article in journal (Refereed)
    Abstract [en]

    In muscle energy technique (MET), palpation is an important tool aimed at detecting asymmetry and selecting interventions. The aim of this study was to test the inter-examiner reliability of static palpation of the transverse processes of L5 (L5), sacral sulci (SS), inferior lateral angles of the sacrum (ILA), and the medial malleoli (MM) in a clinical setting. Twenty-five participants, aged 18–78 years, with low back pain and/or sacroiliac pain with or without radiating pain to the knee, were independently examined by two experienced physiotherapists. For L5, SS, ILA, the proportion of observed agreement was 40–44% and the κ coefficient 0.11 (SE=0.12) to 0.17 (SE=0.10). For MM, the observed agreement was 52% and the κ coefficient 0.28 (SE=0.15). Differences in palpation technique seem to be the most likely source of the low inter-examiner reliability in this study. For clinical practise, continued use of these tests as methods for detecting asymmetry and selecting interventions is of doubtful utility.

    Fysiologisk respons vid gång med stavbälte i jämförelse med stavgång2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning: Bakgrund/syfte: Forskning har visat att stavar är ett bra redskap för att göra gångträning mer intensiv. I den här studien introducerades stavbältet, ett träningsredskap som innebär ytterligare belastning för armarna. Syftet med studien var att undersöka fysiologisk respons vid gång med stavbälte, och jämföra med vanlig stavgång.

    Metod: Åtta manliga deltagare genomförde tre gångtester, ett test med stegrande belastning (stavbälte) och två test med konstant belastning (ett test med stavar och ett test med stavbälte). En stegrande belastning innebar successiv ökning av motståndet. Deltagarna gick på löpband med bestämd hastighet (6 km/h). Under testerna mättes hjärtfrekvens och deltagarna skattade sin upplevda ansträngning enligt Borg’s RPE-skala. Vita markörer (självhäftande väv) placerades på vänster sidas handled samt på stavbältet, och användes för att beräkna armarnas rörelseutslag och effekt med hjälp av rörelseanalysprogrammet Kinovea.

    Resultat: Testet med konstant belastning visade att stavbältet genererade en högre hjärtfrekvens (p=0.012) samt upplevd ansträngning (p<0.001), jämfört med gång med vanliga stavar. En signifikant skillnad på rörelseutslaget (p=0.016) vid gång med stavbälte jämfört med vid gång med stavar. Testet med stegrande belastning visade att hjärtfrekvens och upplevd ansträngning ökade i takt med stegringen av motståndet i stavbältet. Vidare sågs en signifikant positiv korrelation mellan beräknad effekt och hjärtfrekvens (rs= 0.663) och mellan beräknad effekt och upplevd ansträngning (rs= 0.881).

    Slutsats: Stavbältet har potential att göra gångträning mer intensiv än vanlig stavgång, då armarnas ökade involvering i arbetet leder till en högre hjärtfrekvens. Att belastningen i stavbältet kan regleras innebär en möjlighet att träna på önskvärd intensitet.

    Norms for grip strength in children aged 4-16 years2002In: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 91, no 6, p. 617-625Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to provide norms for grip strength in children. A total of 530 Swedish 4-16-y-olds was tested with the instrument Grippit. The instrument estimates peak grip strength over a 10s period, and sustained grip strength averaged across the 10s. The increase in grip strength with age was approximately parallel for boys and girls until 10 y of age, after which boys were significantly stronger than girls. Strong correlations existed between grip strength and the anthropometric measures weight, height and, in particular, hand length. Right-handed children were significantly stronger in their dominant hand, while left-handers did not show any strength difference between the hands. It is therefore suggested that when evaluating grip strength in left-handed children both hands should be assumed to be about equally strong, while right-handed children are expected to be up to 10% stronger with their right hand. Sustained grip strength was consistently about 80-85% of peak grip strength, with somewhat lower values in younger children. The present normative data for peak grip strength were slightly lower than 1980s' data from the USA and Australia, probably because of divergences in age grouping and in instruments used. CONCLUSION: Norms for grip strength including estimates of variation were provided for children aged 4-16 y. These data will enable therapists and physicians to compare a patient's score with the scores of normally developed children according to age, gender, handedness and body measures.

    To determine whether other digits move when normal humans attempt to move just one digit, we asked 10 right-handed subjects to move one finger at a time while we recorded the motion of all five digits simultaneously with both a video motion analysis system and an instrumented glove. We quantified the independence of the digits to compare (1) the different digits, (2) the right versus the left hand, and (3) movements at a self-paced frequency versus externally paced movements at 3 Hz. We also quantified the degree to which motion occurred at the proximal, middle, or distal joint of each digit. Even when asked to move just one finger, normal human subjects produced motion in other digits. Movements of the thumb, index finger, and little finger typically were more highly individuated than were movements of the middle or ring fingers. Fingers of the dominant hand were not more independent than were those of the nondominant hand. Self-paced movements made at approximately 2 Hz were more highly individuated than were externally paced movements at 3 Hz. Angular motion tended to be greatest at the middle joint of each digit, with increased angular motion at the proximal and distal joints during 3 Hz movements. Simultaneous motion of noninstructed digits may result in part from passive mechanical connections between the digits, in part from the organization of multitendoned finger muscles, and in part from distributed neural control of the hand.

    "The balancing act". Licensed practical nurse experiences of falls and fall prevention: a qualitative study2012In: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 12, p. 62-Article in journal (Refereed)
    Abstract [en]

    Background: Falls are common in old age and may have serious consequences. There are many strategies to predict and prevent falls from occurring in long-term care and hospitals. The aim of this study was to describe licensed practical nurse experiences of predicting and preventing further falls when working with patients who had experienced a fall-related fracture. Licensed practical nurses are the main caretakers that work most closely with the patients.

    Methods: A qualitative study of focus groups interviews and field observations was done. 15 licensed practical nurses from a rehabilitation ward and an acute ward in a hospital in northern Sweden were interviewed. Content was analyzed using qualitative content analysis.

    Results: The result of the licensed practical nurse thoughts and experiences about risk of falling and fall prevention work is represented in one theme, "the balancing act". The theme includes three categories: "the right to decide", "the constant watch", and "the ongoing negotiation" as well as nine subcategories. The analysis showed similarities and differences between rehabilitation and acute wards. At both wards it was a core strategy in the licensed practical nurse work to always be ready and to pay attention to patients' appearance and behavior. At the rehabilitation ward, it was an explicit working task to judge the patients' risk of falling and to be active to prevent falls. At the acute ward, the words "risk of falling" were not used and fall prevention were not discussed; instead the licensed practical nurses used for example "dizzy and pale". The results also indicated differences in components that facilitate workplace learning and knowledge transfer.

    Conclusions: Differences between the wards are most probably rooted in organizational differences. When it is expected by the leadership, licensed practical nurses can express patient risk of falling, share their observations with others, and take actions to prevent falls. The climate and the structure of the ward are essential if licensed practical nurses are to be encouraged to routinely consider risk of falling and implement risk reduction strategies.

    One-leg hop kinematics 20years following anterior cruciate ligament rupture: Data revisited using functional data analysis2015In: Clinical Biomechanics, ISSN 0268-0033, E-ISSN 1879-1271, Vol. 30, no 10, p. 1153-1161Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Despite interventions, anterior cruciate ligament ruptures can cause long-term deficits. To assist in identifying and treating deficiencies, 3D-motion analysis is used for objectivizing data. Conventional statistics are commonly employed to analyze kinematics, reducing continuous data series to discrete variables. Conversely, functional data analysis considers the entire data series.

    METHODS: Here, we employ functional data analysis to examine and compare the entire time-domain of knee-kinematic curves from one-leg hops between and within three groups. All subjects (n=95) were part of a long-term follow-up study involving anterior cruciate ligament ruptures treated ~20years ago conservatively with physiotherapy only or with reconstructive surgery and physiotherapy, and matched knee-healthy controls.

    FINDINGS: Between-group differences (injured leg, treated groups; non-dominant leg, controls) were identified during the take-off and landing phases, and in the sagittal (flexion/extension) rather than coronal (abduction/adduction) and transverse (internal/external) planes. Overall, surgical and control groups demonstrated comparable knee-kinematic curves. However, compared to controls, the physiotherapy-only group exhibited less flexion during the take-off (0-55% of the normalized phase) and landing (44-73%) phase. Between-leg differences were absent in controls and the surgically treated group, but observed during the flight (4-22%, injured leg>flexion) and the landing (57-85%, injured leg<internal rotation) phases in the physiotherapy-only group.

    INTERPRETATION: Functional data analysis identified specific functional knee-joint deviations from controls persisting 20years post anterior cruciate ligament rupture, especially when treated conservatively. This approach is suggested as a means for comprehensively analyzing complex movements, adding to previous analyses.

    Curve analyses reveal altered knee, hip, and trunk kinematics during drop-jumps long after anterior cruciate ligament rupture2018In: Knee (Oxford), ISSN 0968-0160, E-ISSN 1873-5800, Vol. 25, no 2, p. 226-239Article in journal (Refereed)
    Abstract [en]

    Background: Anterior cruciate ligament (ACL) ruptures may lead to knee dysfunctions later in life. Single-leg tasks are often evaluated, but bilateral movements may also be compromised. Our aim was to use curve analyses to examine double-leg drop–jump kinematics in ACL-reconstructed, ACL-deficient, and healthy-knee cohorts.

    Methods: Subjects with unilateral ACL ruptures treated more than two decades ago (17–28 years) conservatively with physiotherapy (ACLPT, n = 26) or in combination with reconstructive surgery (ACLR, n = 28) and healthy-knee controls (n = 25) performed 40-cm drop–jumps. Three-dimensional knee, hip, and trunk kinematics were analyzed during Rebound, Flight, and Landing phases. Curves were time-normalized and compared between groups (injured and non-injured legs of ACLPT and ACLR vs. non-dominant and dominant legs of controls) and within groups (between legs) using functional analysis of variance methods.

    Results: Compared to controls, ACL groups exhibited less knee and hip flexion on both legs during Rebound and greater knee external rotation on their injured leg at the start of Rebound and Landing. ACLR also showed less trunk flexion during Rebound. Between-leg differences were observed in ACLR only, with the injured leg more internally rotated at the hip. Overall, kinematic curves were similar between ACLR and ACLPT. However, compared to controls, deviations spanned a greater proportion of the drop–jump movement at the hip in ACLR and at the knee in ACLPT.

    Conclusions: Trunk and bilateral leg kinematics during double-leg drop–jumps are still compromised long after ACL-rupture care, independent of treatment. Curve analyses indicate the presence of distinct compensatory mechanisms in ACLPT and ACLR compared to controls.

    Experiences and consequences for women with hand-arm vibration2010In: Work: A Journal of Prevention, Assessment and Rehabilitation, ISSN 1051-9815 (Print) 1875-9270 (Online), Vol. 35, no 4, p. 431-439Article in journal (Refereed)
    Abstract [en]

    Vibrating machines are used in a variety of occupations. Exposure to hand-arm vibration can cause vascular, neurological, and muscular symptoms in the hands and arms. This qualitative study provides a deeper understanding of the consequences of vibration injuries in women. In depth interviews were conducted with eight women with vibration injuries. The women were metal and wood product assemblers and dental personnel. The transcribed interviews were analyzed in accordance with the grounded theory method.

    The core category in the findings was "{another life}". This was constructed by the categories "consequences for everyday activities", "work performance", "household duties", "leisure", and "self perception" and shows that the injury had affected most parts of the women's lives and decreased their quality of life. The importance of well-functioning hands in all activities was highlighted. Reduced hand function due to numbness, muscle weakness, and pain caused restricted abilities to perform activities at work, at home, and during leisure time. The women described impact on their self-perception, as the injury had affected them in their roles as a worker, mother, and woman. The findings indicate that a vibration injury is a multidimensional problem that can affect every aspect of an individual's life. Health care providers should be aware of these complex consequences.

    Skadeförekomst bland ungdomar på elitnivå inom snowboard och freestyle2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Undersöka skadeförekomsten bland ungdomar på snowboard- och freestylegymnasier i Sverige samt att jämföra skadeförekomsten mellan dessa två discipliner. Metod: Retrospektiv studie baserad på frågeformulär om träningsvanor och skador under läsåret 2011/2012. Totalt 51 av 93 tillfrågade elever (freestyle n=26, snowboard n= 25, bortfall n=42) i årskurs 2-4 från snowboard- och freestylegymnasier ingick i studien. Resultat: Sammanlagt hade 27 av 51 elever (53%) skadat sig. Snowboardåkarna stod för 12 skador (34%) och freestyleåkarna för 23 skador (66%). Måttliga skador, vilket innebär 8-28 dagars frånvaro, förekom mest frekvent bland freestyleåkarna (n=11; 48%). Lätta skador (1- 3 dagars frånvaro, n=4; 33%) och allvarliga skador (>28 dagars frånvaro, n=4; 33%) var vanligast bland snowboardåkarna. Vanligaste kroppsdel att skada bland freestyleåkarna var huvudet (n=6; 26%) följt av skador i fot/häl/tå (n=5; 22%) medan skulderskador (n=4; 33%) var vanligast hos snowboardåkarna. Slutsats: Skadeförekomsten bland ungdomar på snowboard- och freestylegymnasier i Sverige är hög, mer än hälften av eleverna skadade sig minst en gång under läsåret 2011/2012. Bland freestyleåkarna var huvudskador vanligast medan skulderskador var vanligast för snowboardåkarna. Antalet knäskador var lågt bland både snowboard- och freestyleåkare. Ingen signifikant skillnad sågs i antal skadade elever mellan disciplinerna. Resultaten hade varit mer representativa för hela målgruppen om svarsfrekvensen varit högre.

    The mechanical and neuromuscular responses of the tibialis anterior muscle during unexpected perturbations2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

     

    Bakgrund: Tidigare forskning föreslår att m. tibialis anterior kan vara en lämplig proprioceptiv indikator under posturalt svaj i stillastående. Huruvida detta förhållande råder under mer utmanande balansuppgifter är ännu oklart. Ett sätt att undersöka posturala responser hos en person är genom att oförutsett förskjuta underlaget denna står på.

     

    Syfte: Denna studie syftade till att beskriva de neuromuskulära och mekaniska responserna hos m. tibialis anterior under de första 0.3 sekunderna av en oförutsedd förskjutning av underlaget.

     

    Metod: Åtta försökspersoner deltog i studien och genomgick 20 oförutsedda framåt och bakåt förskjutningar av underlaget. Deltagarna stod på ett löpband medan elektromyografi, ultraljud och kinematik spelades in.

     

    Resultat: Initialt under framåt-translationerna av underlaget kunde en förlängning av tibialis anteriors muskelfasciklar observeras tillsammans med en ökad fotledsvinkel och en förlängning av muskel-sen-enheten. Efter cirka 30 ms förkortades fasciklarna snabbt och detta associerades med en stor elektromyografisk aktivitet av m. tibialis anterior. Först efter 150 ms så kunde en minskning av fotledsvinkeln och en förkortning av muskel-sen-enheten observeras.

     

    Konklusion: Under första delen av en framåt-translation av underlaget observerades gynsamma förhållanden hos tibialis anterior för att kunna bidra med proprioceptiv information till det centrala nervsystemet .

    Polisstudenters fysiska kapacitet och deras syn på träning2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion:   Polisyrket är en profession som anses mycket fysiskt krävande. Yrket har även   stora psykiska påfrestningar. Få studier har undersökt hur den fysiska   kapaciteten hos poliser ser ut och förändras från utbildningsstart och   framåt.   Syfte: Syftet med denna studie var   att beskriva polisstudenters fysiska kapacitet gällande kondition och muskelstyrka,   samt deras syn på träning vid polisutbildningens start.   Metod: 92 polisstudenter besvarade   ett frågeformulär angående träning- och motionsvanor under sin första dag på   utbildningen. 46 studenter utförde dessutom ett konditionstest och 35   studenter styrketestades.  Resultat: Studenterna angav att de   tränade både för att öka sin kondition och sin muskelstyrka. Styrketesterna   visade mycket varierande resultat. Fler studenter angav att de tränade för   att klara utbildningen jämfört med de som angav att de tränade för att klara  arbetet. De manliga polisstudenterna hade bättre kapacitet gällande kondition   samt ben- och handstyrka.  Slutsats: Denna studie visade att   fler studenter tränar för att klara utbildningen jämfört med hur många som   tränar för att klara av sitt framtida yrkesliv. Utifrån detta samt en   tidigare studie, kan det tänkas att den fysiska kapaciteten gällande   kondition och muskelstyrka eventuellt försämras under yrkeslivet. Betydelsen   av att träna bör etableras tidigt hos studenterna för att de ska fortsätta   träna under yrkeslivet. Då män och kvinnor skiljer sig gällande kondition   samt ben- och handstyrka bör kanske antagningskraven ses över och eventuellt   anpassas utefter vilken tjänst inom polisen som den sökande vill ha.

    Strategies for exercise assessment and training in patients with chronic obstructive pulmonary disease2010Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Rationale: Chronic obstructive pulmonary disease (COPD) is not only a common lung disease but is a major cause of morbidity and mortality worldwide. Pulmonary rehabilitation (PR) helps optimize function and independence by increasing exercise capacity, reducing symptoms and improving health related quality of life (HRQL). Exercise training is certainly a key component of the PR programs; however, many of its aspects still need to be better defined such as optimal exercise assessment and training modality for these patients. The general purpose of this thesis was to generate new knowledge that could contribute to new strategies for exercise assessment and training in patients with COPD.

    Methods and results: This thesis is comprised of four independent studies. Thigh muscle strength, endurance and fatigue were compared between 42 patients with moderate to severe COPD and 53 healthy controls (Study I). Impaired thigh muscle strength and endurance in patients with COPD was found, except for muscle strength in knee extension in male patients. Female patients had higher fatigue index than female controls while no difference was found between male patients and controls. The six-minute walk test (6MWD) performed on a non-motorized treadmill (6MWD-T) was compared with the 6MWD performed in a corridor (6MWD-C) in 16 healthy elderly subjects (Study II). They performed twelve tests (six 6MWD-C and six 6MWD-T) on two different days in a randomized order. An average discrepancy was found between the two methods with the subjects walking a shorter distance on the non-motorized treadmill. However, the results showed good test-retest reliability between days and test repetitions. A systematic review (Study III) was done of studies that investigated the effects of an arm training program in patients with COPD. The findings of this review indicated that there is evidence that an arm training program improves arm exercise capacity, but its effects on dyspnea, arm fatigue and healthy-related quality of life is unclear. Finally, a two-armed randomized controlled trial examined the effects of an arm training program on arm function, arm exercise capacity, muscle strength, symptoms and HRQL in patients with COPD (Study IV). The groups were randomized to arm training or sham. Compared with the changes observed in the control group, the magnitude of change in the intervention group was greater for arm function, arm exercise capacity and muscle strength. There was no difference between groups in HRQL or symptoms.

    Conclusions: Upper extremity resistance training improves arm exercise capacity, arm function and muscle strength in patients with COPD. Training and assessment of upper and lower limb muscles should be included into PR programs. The 6MWD performed on a non-motorized treadmill may offer an alternative option to the standard 6MWD when a 30-meter corridor is not available.

    Relationship and responsiveness of three upper-limb tests in patients with chronic obstructive pulmonary disease2013In: Physiotherapy Canada, ISSN 0300-0508, E-ISSN 1708-8313, Vol. 65, no 1, p. 40-43Article in journal (Refereed)
    Abstract [en]

    Purpose: To determine (1) the relationship among three common upper-limb tests for patients with chronic obstructive pulmonary disease (COPD): unsupported upper limb exercise test (UULEX), 6-minute pegboard and ring test (6PBRT), and a muscle-strength test using a hand-held dynamometer; and (2) the responsiveness of these three tests to changes after pulmonary rehabilitation that included a resistance arm-training programme.

    Methods: The study was a secondary analysis of a randomized controlled trial (RCT). The UULEX and the 6PBRT were used to measure peak arm exercise capacity and arm function, respectively. A handheld dynamometer was used to measure elbow and shoulder flexion force. We analyzed baseline data for all participants in the ACT, as well as baseline and post-PR data for those who completed 6-week follow-up testing.

    Results: 36 patients with COPD (mean forced expiratory volume in 1 second [FEV1] = 35% [SD 15%] predicted; age 66 [9] y) participated, of whom 13 completed an arm-training programme. The correlations among the test results ranged from 0.41 to 0.81 (p < 0.0001). Standardized response means were 1.0 for muscle force of elbow flexion, 1.2 for shoulder flexion, and 1.8 for the 6PBRT and UULEX.

    Conclusions: Although the three tests (UULEX, 6PBRT, and muscle-strength test using a hand-held dynamometer) are intended to measure different constructs, they were moderately to highly correlated with one another. The 6PBRT, UULEX, and muscle-strength test were demonstrated to be responsive to the resistance arm-training programme.

    Comparison of the 6-minute walk distance test performed on a non-motorised treadmill and in a corridor in healthy elderly subjects2010In: Physiotherapy, ISSN 0031-9406, E-ISSN 1873-1465, Vol. 96, no 3, p. 234-239Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To compare the 6-minute walk distance (6MWD) test performed on a non-motorised treadmill (6MWD-T) with the 6MWD test performed in a corridor (6MWD-C) in healthy elderly subjects.

    PARTICIPANTS: Sixteen healthy elderly individuals.

    DESIGN: Participants performed three 6MWD-T tests and three 6MWD-C tests on two different days.

    OUTCOME MEASURES: Distance walked was recorded in metres. Perceived exertion and leg fatigue were rated on the modified Borg scale before and after each test.

    RESULTS: Using the Bland and Altman limits of agreement analysis method, the mean difference between the two methods was 153.3m (limits of agreement: 28 to 278). The mean difference between days 1 and 2 for the 6MWD-C test was -7.2m (limits of agreement: -45.4 to 30.8), and the mean difference between days 1 and 2 for the 6MWD-T test was -1.6m (limits of agreement: -64.0 to 60.7). The mean difference between the first and second repetitions of the 6MWD-C test was -5m (limits of agreement: -41 to 31), and the mean difference between the first and second repetitions of the 6MWD-T test was -17m (limits of agreement: -85 to 51).

    CONCLUSIONS: The 6MWD-C and 6MWD-T tests are not interchangeable. However, the results showed good test-retest reliability between days and between test repetitions for both tests. Therefore, the 6MWD-T test may offer an alternative option to the 6MWD-C test when a 30-m corridor is not available. These findings may have implications for execution of the 6MWT-T test within cardiac and pulmonary rehabilitation.

    Elite sprinters, ice hockey players, orienteers and marathon runners: isokinetic leg muscle performance in relation to muscle structure and training1987Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In male athletes from different sports, isokinetic knee extensor, and in orienteers also plantar flexor peak torque (PT), contractional work (CW) and integrated surface electromyograms (iEMG) were analysed.

    Single contraction PT, CW and iEMG in sprinters and marathon runners were signi­ficantly correlated to the cross-sectional area (CSA) of m. quadriceps, and to the Type II fibre area of m. vastus lateralis. When correcting PT, CW and iEMG for CSA of m. quadriceps, such correlations were found only for Type IIA fibre area at 180° s~1. Elec- tromyographically, m. vastus lateralis (biopsied muscle) was representative for m. quadriceps. Calculated optimal mean power (CW s~1) and electrical efficacy (CW/iEMG) approximated for sprinters 450° s-1 and for marathon runners 270° s~1, i.e. velocities at or above the upper limit of the dynamometers. In orienteers, plantar flexor PT increased during winter training, but decreased during competitive season. Knee extensor PT increased over the whole year. At 30 and 60° s~1 only knee extensor PT was negatively associated with the running velocity at onset of blood lactate accu­mulation (VOBLA)- Changes in VOBLA during winter period were negatively associated with changes in knee extensor PT at 180° s~1. During competitive season, changes in Vobla were negatively associated with the ratio quality : quantity running. In ice hockey players PT varied non-systematically with training and games.

    The biopsy specimens of marathon runners showed irregular fibre shapes, an in­creased amount of connective tissue and central fibre nuclei, indicating an early strain disease or functional adaptation to extreme demands.

    During repetitive contractions in sprinters and marathon runners, fatigue, i.e. slope of decline in CW, was significantly associated with the Type II fibre area of m. vastus lateralis. For knee extensors of sprinters, ice hockey players and orienteers, a steep de­crease in CW/iEMG was observed. In contrast, knee extensors of marathon runners and plantar flexors of orienteers showed an almost unaltered CW/iEMG throughout the test. The knee extensor endurance level (CW/iEMG) was significantly correlated to the maximal oxygen uptake. In orienteers, an increase in endurance level of both tested muscle groups during winter training parallelled an increase in VOBLA and V02obla- In hockey players, fatigue and endurance pattern (CW and CW/iEMG) changed non-systematically with training and games.

    In conclusion, isokinetic measurements and iEMG reflect the structural properties of the knee extensor muscles in sprinters and marathon runners. The demonstrated characteristics and changes in leg muscle function in different groups of athletes apparently reflect varying demands from different sports activities.

    Measurement properties of the motor evaluation scale for upper extremity in stroke patients (MESUPES)2012In: Disability and Rehabilitation, ISSN 0963-8288, E-ISSN 1464-5165, Vol. 34, no 4, p. 288-294Article in journal (Refereed)
    Abstract [en]

    Purpose: To investigate inter-rater reliability of the Motor Evaluation Scale for Upper Extremity in Stroke patients (MESUPES), to provide estimates of the minimal detectable change (MDC) of the MESUPES and to investigate concurrent validity in relation to the arm scores of the Modified Motor Assessment Scale (M MAS). Methods: Forty-two stroke patients (mean age 56 +/- 12 years) were independently assessed within a 48-hours window by two raters in different pairs (total available raters = 4). Results: Weighted. analysis indicated good to very good agreement at item level (range 0.63-0.96). The relative and absolute reliability of the total score of MESUPES (maximum 58) was high according to the intraclass correlation coefficients (ICC = 0.98) and the standard error of measurement (SEM = 2.68). The MDC for three levels of confidence was calculated: A score change of 8, 7 and 5 is necessary for a MDC to have confidence of 95%, 90% and 80%, respectively, of a genuine change. Correlation between the MESUPES and M MAS was high (r(s) = 0.87). Conclusions: The MESUPES shows high inter-rater reliability, and our study provides useful estimates of MDC for different levels of certainty. Additional research to confirm concurrent validity and to examine other psychometric properties of the MESUPES such as sensitivity is needed.

    Omedelbara effekter på välmående av ett högintensivt funktionellt träningsprogram för personer med demenssjukdom2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte: Utvärdera om ett högintensivt funktionellt träningsprogram ger omedelbara effekter på välmående för personer med demenssjukdom. Bakgrund: Omedelbara effekter av fysisk aktivitet vad gäller exempelvis blodtryck, kolesterol, immunförsvar samt hormonsystem har påvisats. Dock saknas forskning inom området omedelbara effekter på välmående hos personer med demens. Metod: Uppsatsen är en del av The UMDEX Study, en randomiserad kontrollerad studie. 186 personer med demenssjukdom som bodde på särskilt boende deltog. Deltagarna lottades till en högintensiv funktionell träningsgrupp (n=84) och en social aktivitetsgrupp (n=86). 40 möljliga träffar à 45 minuter hölls i små grupper (3-9 personer). Direkt innan och efter varje interventionstillfälle fick en deltagare från varje klustergrupp frågan ”hur känner du dig just nu?”, som besvarades enligt en femgradig skala. Resultat: En signifikant skillnad framkom i skattning av välmående vid en jämförelse före och efter, där ett ökat välmående sågs hos både träningsgruppen (p<0,01) och sociala aktivitetsgruppen (p<0,01). Bland deltagarna i träningsgruppen var det en signifikant större andel av tillfällen med ökat (p=0,03), men även minskat (p=0,01) välmående, jämfört med deltagarna i sociala aktivitetsgruppen. Slutsats: Ett högintensivt funktionellt träningsprogram gav omedelbara effekter på ökat välmående, men även minskat välmående var vanligare förekommande, jämfört med en social aktivitet bland personer med demenssjukdom.

    Ventilated patients' experiences of body awareness at an intensive care unit2005In: Advances in Physiotherapy, ISSN 1403-8196, E-ISSN 1651-1948, Vol. 7, p. 154-161Article in journal (Refereed)
    Abstract [en]

    Treatment with mechanical ventilation (MV) in an intensive care unit (ICU) can cause extensive problems for patients.There is, however, a dearth of research investigation into how ICU treatment affects a person’s body image. The aim of thisstudy was to enhance the knowledge and understanding of body awareness and body image in persons treated with MV in anICU. In order to capture the informants’ own perceptions and experiences, a qualitative method of Grounded Theory waschosen. Seven thematic in-depth interviews were carried out with former ICU patients. To increase credibility, triangulationof researchers and reference group checking was used. The analysis resulted in the core category Limited possibilitiesto act, which relates to the informants’ experiences of not being able to act as they normally would. The core category wasderived from the experiences of feeling like another person, the perceptions of not being in contact with their body andreality and the feeling of being restrained. This study adds a perspective of body awareness to the interpretations of ICUpatients’ experiences. It emphasizes the experience and movement aspects of the body and that physiotherapists have animportant role in the rehabilitation of ICU patients.

    Samband mellan psykologiska och fysiska faktorer hos patienter med utmattningssyndrom2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Långvarig stressbelastning utan möjlighet till adekvat återhämtning kanleda till ett antal sjukdomar som exempelvis utmattningssyndrom (UMS). Goda kunskaper finns idag om patienter med utmattningssyndrom och deras mentala hälsa, men fortfarande saknas kunskap om sambandet med deras fysiska status.Syfte: Syftet med denna studie var att studera samband mellan psykologiska och fysiska variabler hos patienter med utmattningssyndrom.Metod: Utgångsvärden samlades in från en randomiserad kontrollerad studie (ForRest). Studiepopulationen bestod av 99 patienter (85 kvinnor och 14 män) med en medelålder på 44,6 ± 8,6 år, samtliga med diagnosen utmattningssyndrom.Resultat: Signifikant samband påvisades mellan trötthet och konditionsvärde, VO2max, samt dynamisk balans. De patienter som skattade en högre grad av trötthet hade ett lägre VO2-max, ett lägre konditionsvärde samt lägre dynamisk balans.Konklusion: Patienter med UMS har olika utgångslägen vad gäller mental och fysisktstatus och det gäller att möta dessa varierade behov för att hitta en balans mellan vila och regelbunden motion. Därmed kan sjukgymnasten vara en viktig yrkesgrupp i både prevention samt rehabilitering av patienter med utmattningssyndrom.

    Utvärdering av vattenträning inom habiliteringsverksamheten i Västerbotten: En enkätundersökning2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Introduktion: Västerbottens läns landsting (VLL) habilitering bedriver idag vattenträning på 3 orter i Västerbotten. Vårdpersonal ser idag positiva effekter av träningen men har ingen fast metod att utvärdera träningsdeltagarnas individuella upplevelser av träningen.

    Syfte: Att utvärdera hur barn och föräldrar upplever vattenträningen som erbjuds inom Västerbottens läns landstings (VLL) habiliteringsverksamhet.

    Metod: En enkätundersökning skickades per post till föräldrar med barn inskrivna inom VLLs habilitering. Enkäten skickades ut till 43 familjer och 34 av dessa besvarade enkäten

    Resultat: En majoritet upplever att de är nöjda med träningen som bedrivs av VLL.

    Slutsats: Simförmågan förbättrades hos en majoritet av barnen enligt deltagarna. Att denna förbättras ökar barnets möjlighet till delaktighet i många vardagliga sociala sammanhang. Vattenträningen är en uppskattad träningsform hos både det deltagande barnet och de vuxna som finns omkring barnen.
