A 6-Month Follow-up Study on Adherence and Satisfaction with Lower Limb Prostheses and Orthoses Delivered to Community-Dwelling People in Japan.

Abstract: Introduction: We aimed to evaluate adherence and satisfaction with prostheses and orthoses (POs) of the lower extremities delivered to community-dwelling patients and to assess the relationship of adherence and satisfaction with patient background factors, including medical status, physical findings, and level of participation. Methods: : We conducted a descriptive cohort study. Consecutive patients with disability who applied for lower extremity POs were invited to enroll. The patients' background information was collected at enrolment, and they were asked at 6 months after PO delivery whether they were using their PO as expected prior to its delivery, and, on a numerical rating scale (NRS, 0 - 10), if they were satisfied with their POs. Furthermore, the relationship between usage/satisfaction and the participants' backgrounds was evaluated and the participants' comments regarding their POs were summarized. Results: : This study analyzed the data of 51 participants (mean age, 56.5 ± 19 years). At the 6-month follow-up, 45 participants used POs as much as they had expected before delivery; this group was younger than their counterparts (52.7 versus 69.2 years). The median satisfaction score using the NRS was 8.5. Older participants (r = - 0.33), participants who were able to attach and remove their POs, and those who were independent in locomotion scored lower on satisfaction. Other background factors were not different regarding adherence or satisfaction. Conclusions: : This study demonstrated the difficulty in predicting the usage and satisfaction with lower limb POs from users' backgrounds. Producer-user communication, particularly with patients of older age and/or a higher level of participation, may improve adherence and satisfaction.
