Abstract
From the standpoint of motor learning theory, to study the movement of a human somatosensory feedback and inverse model must be proper. This is the healthy subjects were trained from left to right tilt angle of the trunk in a sitting position. However, conduct the training by changing the angle of tilt in the right purpose, and angle for the target to be examined whether somatosensory and inverse model is rebuilt. This proposed training methods including, comparing the three different ways and investigate how effective the training. Consequently suggested that the proposed training method is most effective.
