This paper reports some of the research activities conducted at the Motor Control and Physical Therapy Laboratory aimed to understand the control of the coordination between posture and voluntary actions as reflected in the performance of everyday motor tasks in subject with normal and impaired motor control. Through multi-factorial analysis regarding the kinematics, ground reaction forces and muscle activity patterns (EMG), motor control variables critical for specific task performance are identified. Target-reaching in subjects after stroke and in children with cerebral palsy are discussed in some detail. Further, transfer skills in subjects with spinal cord injury as well as weight shift during gait initiation in young and elderly adults and during clinical balance testing are presented. The research findings are illuminated with respect to clinical implications in neurological rehabilitation, based on the motor control hypothesis.
本文报告了在运动控制与物理治疗实验室开展的一些研究活动，旨在了解姿势与自主动作之间的协调控制，这在运动控制正常和受损的受试者日常运动任务表现中有所体现。通过对运动学、地面反作用力和肌肉活动模式（肌电图）的多因素分析，确定了特定任务表现的关键运动控制变量。详细讨论了中风后受试者和脑瘫儿童的目标达成情况。此外，还介绍了脊髓损伤受试者的转移技能，以及年轻人、老年人在步态起始阶段和临床平衡测试期间的体重转移情况。基于运动控制假说，阐述了这些研究结果对神经康复临床意义的启示。
