To determine whether hemiplegic patients can propel a leg-pedalling wheelchair and whether it is easier and faster for them to pedal the wheelchair using both legs alternately than to propel an ordinary wheelchair with their unaffected hand and leg.
Within-subject comparison.
Subjects comprised 10 hemiplegic in-patients (8 males, 2 females), aged 63.7 (SD 12.7) years with severe or moderate gait disturbance due to stroke.
Subjects were asked to practice propelling the leg-pedalling wheelchair and ordinary wheelchair on both slalom and rectangular courses for a period of 7-10 days. Once they had become skilled in this, the wheelchair speed and patient's heart rate were measured, and a physiological cost index was calculated.
Subjects could pedal the leg-pedalling wheelchair using both legs alternately. The speed of this wheelchair was faster than that of the ordinary wheelchair, and the physiological cost index for pedalling it was lower than that for propelling the ordinary wheelchair. However, subjects needed some help in transferring to the leg-pedalling wheelchair.
The hemiplegic patients could pedal the leg-pedalling wheelchair using both legs alternately faster and more effectively with regard to speed and physiological cost index.
确定偏瘫患者是否能够驱动腿蹬式轮椅，以及他们双腿交替蹬踏轮椅是否比用健侧手和腿推动普通轮椅更容易、更快。
自身对照比较。
10名偏瘫住院患者（8名男性，2名女性），年龄63.7（标准差12.7）岁，因中风导致严重或中度步态障碍。
要求受试者在7至10天的时间内在障碍滑雪道和矩形路线上练习驱动腿蹬式轮椅和普通轮椅。一旦他们熟练掌握，测量轮椅速度和患者心率，并计算生理成本指数。
受试者能够双腿交替蹬踏腿蹬式轮椅。这种轮椅的速度比普通轮椅快，蹬踏时的生理成本指数低于推动普通轮椅时的指数。然而，受试者在转移到腿蹬式轮椅时需要一些帮助。
就速度和生理成本指数而言，偏瘫患者能够双腿交替更快速、更有效地蹬踏腿蹬式轮椅。
