We have developed a system that greatly improves balance by removing visual information of the external world during gait training and further by visual feedback of somatic sensation information. The somatic sensation information used for feedback was foot pressure distribution and joint angle information, which is somatic sensation information used during gait. In the verification experiment, we compared training with the feedback system and the training in the visual sense cutoff state without the feedback system. The performance index of the balance ability was the standard deviation σ of right-and-left directions of the CoP traces. The result revealed that σ increased by 0.61 times by the FB training, and balance ability was improved. Further, the effect of the FB training was more significant than that of visual interception training. This suggests that the visual interception system improves balance, and that visual feedback increases its effects.
