Preliminary Study: Effects of Visual Distortion on Standing Balance Motion Amplitude and Visual Dependency on an Unstable Surface

Visual feedback is a common method to enhance motor learning and is widely used in rehabilitation institutes. Although balance training with visual feedback has shown positive results, the most effective way to provide the feedback is still open to research. We investigated the effect of visual distortion during end-point excursion training on an unstable surface with healthy participants. We demonstrated that visually reduced amplitude of motion during a training period can challenge participants to increase their maximal end-point excursion and has the potential to decrease the visual feedback dependency.
