Objective: The aim of this study is to clarify the effect of suppressing the significant enhancement of the sense of insecurity and sympathetic function that occurs with the operation carried out under non-visual. Subjects and Methods Subjects: Ten subjects healthy young (age 21±2 years). They wear an eye mask. Design: experimental study Setting: Motion analysis laboratory in Institute Main outcome measurements Motion stability: to measure the duration of body position in five of the motion, was the mean and variance value. A sense of insecurity Visual Analog Scale (VAS) and heart rate variability frequency measurement of the measured RR wave (LF/HF) Results: Motion stability is duration of body position as a result of motor learning is the first time as a baseline, at the start of the operation of the last time 8 weeks and operation stability after the end of five minutes, the mean and the variance value Conclusion: In simulated visually impaired subjects who had an eye mask, the system gave a self-body image. Position on the support base surface of the subject, position on the sagittal plane, and before using the position information on face value, a sense of insecurity Visual Analog Scale, VAS of suppression is expected.
