The objective of this study was to measure how, why, and where the power adjustable seat height (PASH) system of Quantum's iLevel® wheelchairs were used. We instrumented iLevel® power wheelchairs for 24 adults to measure wheelchair occupancy, seat height, in-seat activity level, and bouts of mobility. Participants elevated their wheelchair 3.9 (4.4) (mean (SD)) times per day, including 1.0 (1.6) times per day past 9". Twenty-nine percent of elevation events were transient, lasting < 1 min, while 42% of elevate events lasted >5 minutes. Sixty-seven percent of participants transferred while elevated at least once, typically from heights <5" or >9", and 14 people changed their seat height between the transfer to and from the wheelchair. Twenty-three of 24 participants wheeled while elevated. Finally, in-seat activity level was greater while elevated. For many participants, the PASH system provided a functional benefit on a daily basis. Individuals elevated 4 times per day for activities including transfers, reach, gaze, or mobility. However, 14 participants did not elevate on at least 1 day. Further study is needed to identify the characteristics of people who will benefit most from a PASH system as well as to document the value associated with PASH system use.
本研究的目的是测量昆腾iLevel®轮椅的电动可调节座椅高度（PASH）系统的使用方式、原因和地点。我们为24名成年人的iLevel®电动轮椅安装了仪器，以测量轮椅的占用情况、座椅高度、座位内活动水平和移动次数。参与者每天将轮椅升高3.9（4.4）次（均值（标准差）），其中超过9英寸的升高次数为每天1.0（1.6）次。29%的升高事件是短暂的，持续时间<1分钟，而42%的升高事件持续时间>5分钟。67%的参与者在至少一次升高状态下进行了转移，通常是在高度<5英寸或>9英寸时，并且有14人在进出轮椅的转移过程中改变了座椅高度。24名参与者中有23人在升高状态下进行了轮椅推进。最后，升高状态下的座位内活动水平更高。对于许多参与者来说，PASH系统每天都提供了功能上的益处。个体每天为了包括转移、够取、注视或移动等活动而升高4次。然而，有14名参与者至少有1天没有升高座椅。需要进一步研究以确定最能从PASH系统中受益的人群特征，并记录与使用PASH系统相关的价值。
