Elbow movement during voluntary positioning of the hand (with the arm supported against gravity) is described in a longitudinal study of five patients recovering from hemiplegia due to stroke. Over a twelve month period, four of the patients improved their speed of movement, three exhibiting slightly better recovery of elbow extension, one of flexion. In some instances co-contraction of the elbow agonist and antagonist (measured just before the onset of movement) decreased with time after stroke. The effects of contrasting movements at the shoulder on elbow movement were also studied. Estimates of recovery were generally similar whether patients kept the shoulder still or made movements that were synergic or counter-synergic to those of the elbow.
在一项对五名因中风导致偏瘫正在恢复的患者的纵向研究中，描述了手部自愿定位（手臂支撑以对抗重力）过程中的肘部运动。在十二个月的时间里，四名患者提高了运动速度，三名患者的肘部伸展恢复稍好，一名患者的肘部屈曲恢复稍好。在某些情况下，中风后随着时间的推移，肘部主动肌和拮抗肌的共同收缩（在运动开始前测量）有所减少。还研究了肩部相反运动对肘部运动的影响。无论患者是保持肩部静止，还是进行与肘部协同或反协同的运动，恢复情况的评估总体上相似。
