本研究探讨电动座椅功能的使用，包括倾斜空间，靠背斜倚，座椅升降，在一组轮椅使用者在他们的典型的日常活动。12名使用具有座椅功能的电动轮椅的人参加了这项研究。他们驾驶自己的轮椅，并在社区环境中根据需要使用座椅功能约2周，同时使用便携式设备记录座椅功能的使用情况。我们发现受试者每天占用轮椅11.8 +/- 3.4小时（所有数据均显示为平均值+/-标准差）。当他们坐在轮椅上时，他们每天分别获得空间倾斜、靠背倾斜和座椅提升19 +/- 14次（64.1% +/-36.8%）、12 +/- 8次（76.0% +/-29.8%）和4 +/- 4次（22.5% +/-34.9%）。受试者每天有39.3% +/- 36.5%的时间选择在轮椅上保持倾斜和斜倚姿势。他们花了很少的时间在完全直立的位置。受试者每53.6 +/- 47.0分钟改变一次坐姿。在不同的座位压力的位置上花费的时间在受试者之间存在差异。所收集的数据可加强提供轮椅的临床实践，使轮椅使用者更好地遵守临床指示和适当使用座椅功能。
This study examined the usage of powered seating functions, including tilt-in-space, backrest recline, and seat elevation, among a group of wheelchair users during their typical daily activities. Twelve individuals who used a power wheelchair with seating functions participated in the study. They drove their own wheelchair and used the seating functions as needed in their community environment for about 2 weeks while the seating function usage was recorded with a portable device. We found that Subjects occupied their wheelchair for 11.8 +/- 3.4 hours a day (all data shown as mean +/- standard deviation). While occupying their wheelchairs, they accessed tilt-in-space, backrest recline, and seat elevation 19 +/- 14 times a day for 64.1% +/- 36.8%, 12 +/- 8 times for 76.0% +/- 29.8%, and 4 +/- 4 times for 22.5% +/- 34.9%, respectively. Subjects chose to stay in tilted and reclined positions in their wheelchair for 39.3% +/- 36.5% of their time each day. They spent little time in a fully upright position. Subjects changed their seating positions every 53.6 +/- 47.0 minutes. Time spent in positions of different seating pressures varied among subjects. The information collected could enhance clinical practice of wheelchair provision, resulting in better compliance with clinical instructions and appropriate use of seating functions among wheelchair users.
