Abstract [en]

Background: Patients with Parkinson’s disease (PD) and Essential tremor (ET) who havebeen treated with Deep Brain Stimulation (DBS) generally experience a positive effect,particularly regarding the motor symptoms. However, the patients’ communication skillsare often negatively affected and the assessment instrument currently used withinneurological clinical care is not sufficiently sensitive to assess these patients’ speechclarity, voice and intelligibility satisfactorily.Aim: This study’s purpose was to develop a prototype assessment tool for speech clarity,intelligibility and voice, with speech and language pathology (SLP) validity, that isadaptable to a neurological clinical care setting.Method: The assessment tool was designed using general design methodology. Aprototype was constructed and tested on speech samples of read text for reliability. ThreeSLP’s, three DBS nurses and three naive listeners (NL) were represented in the test group.Levels of agreement were calculated using Percent Close Agreement, PCA.Results: The results indicate a relatively high level of agreement between the groups, inparticular the SLP group and the DBS group (μ: 0.82, 0.79, and 0.74).Conclusion: The results demonstrate the need for an assessment tool with SLPcompetence to assess speech clarity, intelligibility and voice within neurological clinicalcare. The assessment tool was shown to be a useful and adequate prototype that can easilyevolve into a truly useful and versatile perceptual speech assessment tool. The results ofthis study should be treated cautiously, considering the test groups’ modest size.

Abstract [sv]

Bakgrund: Patienter med Parkinsons sjukdom (PD) och patienter med Essentiell tremor(ET) som behandlats med Deep Brain Stimulation (DBS) upplever i allmänhet en positiveffekt, framför allt gällande de motoriska symtomen. Emellertid påverkas oftapatienternas kommunikativa färdigheter negativt. De bedömingsmaterial som användsinom den kliniska nerurologiska vården; UPDRS/ETRS är alltför trubbiga för att kunna geen tillfredsställande bild av patientens tal, röst och förståelighet.Mål: Skapa ett bedömningsverktyg för tal, förståelighet och röst med logopedisk validitet,och som kan användas inom den kliniska neurologiska verksamheten i samband medDBS-behandling.Metod: Bedömningsverktyget designades enligt generell designmetodik. En prototypskapades och testades för reliabilitet på röstexempel av en läst text. Tre logopeder, treDBS-sköterskor och tre naiva lyssnare deltog i testningen. Grad av samstämmighetberäknades med Percent Close Agreement, PCA.Resultat: Resultaten indikerar en relativt hög grad av samstämmighet mellan grupperna(μ: 0.82, 0.79, respektive 0.74). Logopederna bedömde nästan alla röstexempel sompatienter i behov av logopedhjälp. DBS-gruppen och gruppen med naiva lyssnarebedömde ett mindre antal ha behov av logoped.Slutsats: Resultaten belyser behovet av ett bedömningsverktyg med logopedisk validitetför bedöming av tal, förståelighet och röst inom den kliniska neurologiska verksamheten.Bedömingsverktyget som framtagits i denna studie är en användbar och adekvat prototypsom enkelt skulle kunna utvecklas till ett verkligt användbart och mångsidigt perceptuelltbedömningsmaterial. Dock ska resultaten i denna studie tolkas en smula försiktigt medtanke på de låga antalet deltagare.
