Abstract
Residual limb wounds or ulcers are one of the most frequent skin problems reported by lower extremity prosthesis users. Healing often requires prosthesis disuse, which can logically impair physical functioning. However, there are limited data available to support this idea. We report the impact of prosthesis disuse by presenting assessments of balance, gait, physical activity, and balance confidence obtained on a case subject before experiencing a wound and following reintroduction to a well-fit prosthesis after wound-related prosthesis disuse. The case subject was a 76-year-old male who suffered a unilateral, transtibial amputation due to synovial sarcoma 13 years before. After presenting with a history of pain in the area of a chronic skin plaque, he received a punch biopsy, which resulted in 4 weeks of prosthesis disuse followed by 12 weeks of limited use before a final well-fitting socket was received. The following data were collected 24 weeks before the biopsy and 4 weeks after receiving the final well-fitting socket: Berg Balance Scale, L-test of walking, quantitative gait analysis, Activity-specific Balance Confidence Scale, and 1 week of community-based activity. Balance confidence decreased nearly 19%, walking speed decreased by 12%, and steps/day decreased by 19% following ∼4 months of prosthesis disuse/limited use; functional measures were not impacted. Lower balance confidence is not trivial as it can lead to activity avoidance and increased fall risk. Interventions to target balance confidence changes following prosthesis disuses may be important to minimize the impact of disuse on physical and mental well-being.This publication has 31 references indexed in Scilit:
