Practical assistive device for sit-to-stand tasks

Physically weak people require support for standing up and sitting down. The purpose of this study is to develop an assistive device for sit-to-stand task in daily life. The device can support not only for standing-sitting motion but also for setting some places easy in house. And users can use the device by oneself or with caregivers. The muscle activity has been observed by using surface myoelectric potential sensor for verifying performance of the proposed assistive device.
