Therapy to restore functional movement of stroke patients is based on assumptions about the deficits that occur in motor control as a result of stroke. Success has been limited, perhaps as a result of insufficient information concerning the characteristics of movement after stroke. In this pilot study, the Waterloo Spatial Motion Analysis Recording Technique (WATSMART), an optoelectric motion analysis system, was used with surface electromyography to measure voluntary reaching in the impaired and unimpaired arms of 5 subjects with left hemiparesis. The ability to reach in a smooth coordinated way was significantly poorer in the impaired arms than in the unimpaired arms, for which scores were essentially normal. The patients were less able to activate the muscles of the impaired arm and, as a result, used a greater percentage of the maximum activity they could generate to complete the unresisted reaching task. The electromyographic differences between arms, however, did not reach significance. The results corroborate previous findings and show that movement deficits of particular patients can be diagnosed precisely with kinematic analysis and electromyography. If greater precision in diagnosis were available clinically, more effective therapy might be developed.
恢复中风患者功能运动的治疗基于对中风导致的运动控制缺陷的假设。治疗效果有限，可能是由于关于中风后运动特征的信息不足。在这项初步研究中，光电运动分析系统滑铁卢空间运动分析记录技术（WATSMART）与表面肌电图一起用于测量5名左半身轻瘫患者患侧和未患侧手臂的自主够物动作。患侧手臂以平稳协调方式够物的能力明显比未患侧手臂差，未患侧手臂的得分基本正常。患者激活患侧手臂肌肉的能力较弱，因此在完成无阻力够物任务时，使用了他们所能产生的最大活动量的更大百分比。然而，两侧手臂之间的肌电图差异并不显著。研究结果证实了先前的发现，并表明通过运动学分析和肌电图可以精确诊断特定患者的运动缺陷。如果临床上能有更高的诊断精度，或许就能开发出更有效的治疗方法。
