This study was undertaken to determine whether the direction of trunk rotation would have any effect on trunk muscle performance of post-stroke hemiplegic patients. The design consisted of a nonrandomized control trial in a setting of secondary care (rehabilitation unit at hospital facility). The subjects included 65 hemiplegic patients (50 males) and age-matched 80 healthy controls (38 females). Isokinetic trunk rotatory muscle performance at angular velocities of 60, 120, and 150 degrees per second was measured by using an isokinetic dynamometer (Cybex Torso Rotation Unit). There were no significant differences in the peak torque and best work between the right and left directions of the trunk rotation in the hemiplegic patients or in healthy controls, regardless of the gender of the subjects (paired t test, P > 0.05). The muscle performance of the hemiplegic patients was significantly lower than that of the controls for both genders (t test, P < 0.05). In the hemiplegic patients, the direction of trunk rotation does not affect the trunk rotatory muscle performance, although the performance itself was slightly decreased.
本研究旨在确定躯干旋转方向是否会对中风后偏瘫患者的躯干肌肉表现产生任何影响。该设计为二级护理环境（医院设施中的康复单元）下的非随机对照试验。研究对象包括65名偏瘫患者（50名男性）和80名年龄匹配的健康对照者（38名女性）。使用等速测力计（Cybex躯干旋转单元）测量在每秒60度、120度和150度角速度下的等速躯干旋转肌肉表现。无论受试者性别如何，偏瘫患者或健康对照者在躯干旋转的左右方向之间，其峰值扭矩和最佳功均无显著差异（配对t检验，P>0.05）。无论男女，偏瘫患者的肌肉表现均显著低于对照组（t检验，P<0.05）。在偏瘫患者中，躯干旋转方向不会影响躯干旋转肌肉表现，尽管其表现本身略有下降。
