Twenty patients who had almost completely recovered from hemiparesis following unilateral cerebrovascular accident and 16 control subjects had to perform motor learning tasks including a three-dimensional motor problem and two standard precision tests. The ability of hemiparetic patients to solve simple spatial-motor problems and to gain by training was preserved with limitations concerning high precision control. However, hemiparetic patients had a higher demand for time and corrections, as well as a reduced consistency of performance. Thus recovery from hemiparesis was accompanied by reduced skillfulness and automaticity of motor control.
20例单侧脑血管意外后几乎完全从偏瘫中恢复的患者和16名对照受试者必须执行运动学习任务，包括一个三维运动问题和两项标准精度测试。偏瘫患者解决简单空间运动问题并通过训练获得提高的能力得以保留，但在高精度控制方面存在局限性。然而，偏瘫患者对时间和纠正的需求更高，并且表现的一致性降低。因此，偏瘫恢复伴随着运动控制的熟练程度和自动性降低。
