Abstract
As the later-stage elderly population will continue to grow more,“ locomotive syndrome”is focused. Locomotive syndrome is a condition that reduces mobility due to musculoskeletal ambulation disorder, and it needs long-term care. As gait disorder is increasing, Activities of Daily Living (ADL) of the later-stage elderly is decreasing. In such situation, it is important that senior’s walking movement are recorded and collected to take measures. But now, it is difficult to collect data of senior’s walking movement because of motion capture is located on studio in Laboratory. Therefore, I try to design portable senior ‘s walking movement trace system.
