Post-stroke gait dysfunction is characterized by reduced gait velocity and stride length, along with gait asymmetry and instability. Gait asymmetry and instability are considered as indicators for gait quality, which affect independence and quality of life in individual with stroke. Previous studies have suggested that gait biofeedback is a promising strategy for enhancing the efficacy of post-stroke gait training. However, there is insufficient evidence on the effects of kinematic biofeedback gait training on gait asymmetry and instability in individuals with stroke. Therefore, the purpose of this study is to investigate the effects of real-time kinematic gait biofeedback training on gait quality in individuals with stroke.
