Twenty subjects were examined 4-6 weeks after stroke to establish whether a sensory-motor ipsilateral deficit occurs early after stroke. Each underwent a timed test of repetitive side-to-side movement of both the upper and lower limbs ipsilateral to the cerebral infarct, and an assessment of motor disability using the Motor Assessment Scale. Results were compared with a group studied almost a year after their stroke, and with 41 age-matched healthy volunteers. There was a significantly worse performance (p < 0.005) on the right ipsilateral side, but not the left ipsilateral side, compared with normal volunteers, a finding similar to that of a group previously studied about a year after the stroke. There was no relationship between the severity of the motor deficit and performance of the side, possibly owing to reduction in cerebral activation as a result of a right hemispheric lesion. These observations have importance in rehabilitation and education as well as practical skills, including driving a car and maintaining balance.
20名受试者在中风后4至6周接受检查，以确定中风后早期是否会出现感觉运动同侧缺陷。每位受试者都对脑梗死同侧的上肢和下肢进行了重复性左右运动的定时测试，并使用运动评估量表对运动功能障碍进行了评估。将结果与一组中风后近一年进行研究的受试者以及41名年龄匹配的健康志愿者进行了比较。与正常志愿者相比，右侧同侧的表现明显更差（p < 0.005），但左侧同侧则不然，这一发现与之前一组中风后约一年进行研究的结果相似。运动缺陷的严重程度与该侧的表现之间没有关系，这可能是由于右半球病变导致大脑激活减少所致。这些观察结果在康复、教育以及包括驾驶汽车在内的实践技能方面都具有重要意义。
