Overview
This randomized controlled study aims to investigate the effects of virtual reality (VR)-assisted gait training, in addition to Complex Decongestive Therapy (CDT), on gait parameters, physical function, quality of life, and edema levels in patients with lower extremity lymphedema. Lymphedema is a progressive condition characterized by the accumulation of protein-rich fluid due to lymphatic drainage insufficiency, leading to chronic inflammation and fibrosis. It impairs gait patterns and reduces functional mobility. VR technologies, such as the RehaWalk system, provide interactive, personalized rehabilitation environments that enhance motor learning, motivation, and adherence to treatment. The study evaluates spatiotemporal gait parameters, three-zone foot analysis (heel, midfoot, forefoot), limb circumferences, ultrasound measurements (dermis, epidermis, subcutaneous fat thickness), and patient-reported outcomes. VR-based training offers a novel, engaging approach to improve physical rehabilitation outcomes in patients with lower limb lymphedema. No significant risks are expected in this study.
