活動情境中目標物距離對腦中風病患伸手及物動作之影響
Effects of Target Distance in Task Context on Reaching Performance in Patients with Stroke
摘要
探討視覺目標物距離對中風後伸手及物動作（軀幹與手臂的運動學表現，以及兩者在時間及空間上的協調情形）的影響。25名初次且單側中風病人在三種距離下使用非患側手執行按鈴任務：手長範圍內、近乎手長、及手長範圍外。以隨機採樣重覆施測設計，藉由運動學分析來探討軀幹及手臂的動作表現，包括時間、空間的變化及軀幹－手臂的協調情形。當距離增加時，軀幹及手臂的速度、動作時間、位移量及角度變化量都會增加。軀幹及手臂協調的控制模式為：以時間論，軀幹比手臂先開始動作；以空間論，不論目標物的距離遠近，動作後段的位移主要由軀幹貢獻。目標物距離影響非患側手和軀幹的動作，特別在時間及空間的協調上；軀幹除了維持姿勢穩定之外，還涉及在動作結束前將手引導到目標物上。

To examine the effect of target distance on movement performance in persons after stroke by studying the voluntary movement of trunk and arm and the coordination between trunk and arm during reaching for the visual target. Twenty-five persons with first-ever and unilateral stroke used their less-affected arm to perform a reaching task. Participants were tested under three conditions: targets placed within arm length, at arm length, and beyond arm length. This study used a randomized, repeated measures design. Kinematic variables of reaching movements were analyzed, including spatio-temporal characteristics and coordination between the trunk and arm. As reaching distance increased, the speed, movement time, displacement and angular changes of the joints increased. Whenever the trunk was involved, there was a stereotyped sequential recruitment of the arm and trunk in that the trunk began moving before the hand. The trunk played an important role in positioning the hand close to the target during the terminal stage of the reaching movement. Reaching distance affected the spatial and temporal coordination between the trunk and arm. The trunk not only acts as a postural stabilizer during reaching, but also becomes an integral component in positioning the hand close to the target.
