Abstract

Sit-to-stand (STS) activity from a chair is an important motion in daily life. Some commercial products assist with STS activity in toilet use. These products control seat orientation by changing three parameters, i.e., seat height, tilt, and shift in a forward-backward direction. The reason for selection of these three parameters for seat orientation control has not been reported. Moreover, there are no reports on the best combination of these parameters. Therefore, in this study, we investigated the relationship between ease of STS activity and seat orientation during STS activity. We found that seat tilting provided good support for STS activity when the seat was in a high position (0.55 m), and shifting the seat forward provided good support for STS activity when the seat was higher than 0.45–0.55 m.
