Abstract

Objective: To investigate the use of custom-made knee-ankle-foot-orthoses in daily life and differences in usability factors of knee-ankle-foot-orthoses between users and discontinued users.

Design: Cross-sectional survey study.

Subjects: A total of 163 polio survivors provided with a knee-ankle-foot-orthosis at an outpatient clinic of a university hospital.

Methods: Use and usability of knee-ankle-foot-
orthoses in daily life were assessed with a postal questionnaire. Usability factors were formulated using the International Organization for Standardization (ISO) 9241-11 standard.

Results: A total of 106 respondents (65%) returned the questionnaire. Of these, 98 were eligible for analysis. Seventy-four respondents (76%) reported using their knee-ankle-foot-orthosis. Compared with discontinued users (24%), users experienced more limitations when walking without an orthosis (p = 0.001), were more often experienced with wearing a previous orthosis (p < 0.001) and were more often prescribed with a locked rather than a stance-control knee-ankle-foot-orthosis (p = 0.015). Furthermore, users reported better effectiveness of their knee-ankle-foot-orthosis (p < 0.001), more satisfaction with goals of use and knee-ankle-foot-orthosis-related aspects (p < 0.001).

Conclusion: The majority of polio survivors used their custom-made knee-ankle-foot-orthoses in daily life. Factors related to continued use, such as walking ability without orthosis, expectations of the orthosis, previous orthosis experience and type of knee-ankle-foot-orthosis provided, should be considered and discussed when prescribing a knee-ankle-foot-orthosis in polio survivors.
