本研究的目的是描述全职轮椅使用者在座位上的运动和体重转移行为。我们测量了28名使用手动轮椅作为主要移动设备的人192 d的日常坐姿行为。为了获得测量结果，我们使用了八个薄的力传感器放置在参与者的轮椅坐垫下。在一个典型的日子里，参与者平均在轮椅上花费10.6 +/- 3.0小时，从轮椅上转移8.4 +/- 4.3次。参与者坐在椅子上每小时只进行0.4 +/- 0.5次减压（整个臀部90%的卸载至少15秒），但他们进行重量转移（WS）（至少一侧臀部30%-90%的卸载15秒），频率为每小时2.4 +/- 2.2次。尽管WS的频率较高，但并未以常规方式进行。研究的一半天数包括一段持续至少2小时的直立坐姿，没有WS。鉴于这些观察结果，我们得出结论，座椅评估应强调个人的定位方式，以方便以安全的方式达到、倾斜和转移，不仅是为了改善功能，而且还影响臀部负荷。
The objective of this study was to describe the in-seat movement and weight-shifting behavior of full-time wheelchair users. We measured everyday sitting behavior for 192 d across 28 individuals who used manual wheelchairs as their primary mobility device. To obtain the measurements, we used eight thin force sensors placed under participants' wheel-chair cushions. On a typical day, participants spent an average of 10.6 +/- 3.0 h in their wheelchair and transferred out of the wheelchair 8.4 +/- 4.3 times. Participants only performed pressure reliefs (90% off-loading of the entire buttocks for at least 15 s) 0.4 +/- 0.5 times per hour they were seated in the chair, but they performed weight shifts (WSs) (30%-90% off-loading of at least one side of the buttocks for 15 s) with a frequency of 2.4 +/- 2.2 times per hour. Despite the higher frequency of WSs, they were not performed in a routine manner. Half of the days studied included one segment of upright sitting lasting at least 2 h without a WS. Given these observations, we conclude that seating evaluations should emphasize positioning individuals in a way that facilitates reaching, leaning, and transferring in a safe manner, not only to improve function but also to affect buttocks loading.
