The objective of the present study was to examine time-related changes in motor performance of daily tasks of the upper extremity ipsilateral to the side of lesion in poststroke hemiparetic patients.
Nine patients after an acute uniliteral cerebrovascular accident and 10 age-matched healthy controls were studied. Functional motor abilities of the upper extremity ipsilateral to side of lesion were examined over a 4-month time course, using validated measurement tools (Jebsen test of hand function, nine-hole peg test, and three functional activities of daily living).
The results indicated a significant impairment in the motor function of the hand ipsilateral to the side of brain lesion in comparison with the matched extremity in control subjects. They also pointed to time-related improvement in performance speed, implying that the deterioration in the functional performance of the upper extremity on the uninvolved body side of poststroke hemiparetic patients is not static and may improve with time. The findings further suggested that the left hand of patients with an intact right cerebral hemisphere improves more than does the right hand of their peers whose left cerebral hemisphere is intact.
Due to the small sample size and methodologic considerations, further and more extensive work is required to determine difference in improvement in motor abilities of the ipsilateral left versus the ipsilateral right upper extremities in stroke survivors.
本研究的目的是检测中风后偏瘫患者患侧上肢日常任务运动表现随时间的变化。
对9例急性单侧脑血管意外患者和10例年龄匹配的健康对照者进行研究。使用经过验证的测量工具（杰布森手功能测试、九孔插板测试和三项日常生活功能活动），在4个月的时间内对患侧上肢的功能运动能力进行检测。
结果表明，与对照组匹配的肢体相比，脑损伤侧同侧手的运动功能存在显著损害。结果还表明运动速度随时间有所改善，这意味着中风后偏瘫患者未受累身体侧上肢功能表现的恶化并非一成不变，可能会随时间改善。研究结果进一步表明，右半球完整的患者左手的改善程度大于左半球完整的同龄人右手的改善程度。
由于样本量小和方法学方面的考虑，需要进一步开展更广泛的研究，以确定中风幸存者患侧左上肢与患侧右上肢运动能力改善的差异。
