Outline of Final Research Achievements	This study investigated EMG and motion during standing and stepping motions in submerged and non-submerged conditions. In the standing motion, the submerged condition showed lower EMG and similar motion between two conditions. In addition, EMG pattern in the submerged condition became close to the non-submerged condition in according to the immersed level was decreased. The mean EMG was lower but integrated EMG was similar or higher in the submerged condition than the non-submerged condition when stepping motion was conducted with larger knee and hip joint range of motion. Therefore, the standing and stepping motions in the submerged condition seemed to be a effective exercise for preventing and regaining these motion's ability in real world condition. The development of application software for data feedback has also been conducted in the last year.
