Abstract [en]

This paper has evaluated a new type of prosthetic foot, X-Balance, which aim was to facilitate the performance on uneven ground for the user. This study have performed gait analyzes with three prosthetic feet, the X-Balance, Flex-Foot and assure Ottobock9192 on flat and uneven surfaces using 3D analysis system QTM (Qualisys Track Manager) and associated force plates. During the project a prototype of a design that can perform a mechanical gait were manufactured. The prototype has then been used to fulfill the purpose and objective of this study which is to make different final sets that demonstrate differences between prosthetic feet. Gait analyses of individuals have also been performed to get an idea of what normal gait is. The reliability of the prototype was measured and compared to the study with individuals. By comparison, it could be established that the structure had a higher reliability than the individuals, thus making it easier to compare prosthetic feet against each other. There are no measurements to show that proves that the mechanical gait with the prototype has a high validity. The evaluation findings shows that Ottobock9192 reduce the forces in the Z- and Y-direction most and thus contributes to a gentler heel strike than the other two prosthetics. The results also shows that X-Balance allows greater flexibility in sideway direction (supination) and contributing to a more gentle and easier gait for the user once operate the prosthetic foot over an object with the medial part of the forefoot.
