User experience of lower-limb orthosis

Abstract

If an assistive device is not acceptable to the user, it will not achieve efficacy and would be resource-wasting. This study employed in-depth interviews to understand what users' individual activities of daily living, problems of using orthoses, and considerations for selecting orthoses are. We conducted qualitative interviews with 35 lower-limb orthosis users, and semi-structured interviews were applied in this study. We analyzed the interview data from transcripts, through coding and concepts, to theories based on grounded theory. The results showed that problems of using orthoses are mostly related to activities of daily living of the user and user's expectation. Therefore, in order to enhance its efficacy and use intention, the design and prescribing process of orthoses need to address the problems in the light of activities of daily living and user education.
