Improving Dynamic Balance in Adults with Unilateral Below-Knee Amputation Using Virtual Reality Compared to Standard Rehabilitation

What this Trial Is About

Researchers are evaluating dynamic balance improvements for adults with unilateral transtibial amputations undergoing initial rehabilitation. The study compares a virtual reality-based rehabilitation program with a standard treadmill walking protocol to see which better improves dynamic balance. The goal is to enhance gait patterns and prosthesis use, which can improve overall autonomy for amputees. Virtual reality combined with movement analysis allows personalized treatment and objective progress assessment. Participants are randomly assigned to one of two groups. The experimental group receives a progressive virtual reality rehabilitation protocol involving various exercises with mechanical perturbations, virtual and augmented reality interactions, and visual or audio biofeedback to modify gait patterns. The control group participates in a treadmill walking protocol with virtual reality immersion but without disturbances or prompts to change walking patterns. The rehabilitation lasts 45 days with sessions spread over this period. During the study, participants gait and balance are assessed before and after the rehabilitation period using measurements like mediolateral instability, step variability, cadence variability, center of mass variability, mobility, balance, aerobic endurance, functional capacity, and fall risk. These assessments help track improvements in dynamic balance and overall mobility. Participants are monitored throughout to evaluate the impact of each rehabilitation approach, with the study expected to complete in December 2026.
