What this Trial Is About
Researchers are evaluating a walking training program designed to improve walking skill and confidence in people who use lower limb prostheses. The study aims to overcome challenges related to falling and fear of falling that affect mobility, quality of life, and health in prosthesis users. This pilot research focuses on testing the feasibility and refining the training methods for future rehabilitation practices. Participants will be randomly assigned to one of two groups: one receiving training on a flat surface and the other on an uneven surface. Training involves walking practice on a treadmill or mat three times per week for four weeks. The program gradually increases difficulty by reducing handrail use, increasing walking speed, and making the surface more uneven for the uneven terrain group. Throughout the study, participants' adherence to the training sessions will be monitored. Various assessments will be conducted before and shortly after the intervention, including balance confidence, walking tests, and activity levels. Researchers will also evaluate protocol acceptability and recruitment feasibility. The total participation period covers the four weeks of training with monitoring of walking variability and performance outcomes.
