Biomechanics of Upper Extremity function following Stroke.

描述(由申请人提供)： 卒中是美国成年人慢性残疾的最常见原因，65%的中风后患者无法将偏瘫的上肢纳入日常功能。即使中风后上肢功能轻微受损，也会导致日常功能严重受限，并已被证明对与健康相关的生活质量产生负面影响。这项研究的主要目的是确定预测家庭中手臂使用量的生物力学变量。在实验室中将测量上肢在完成和抓住任务时的运动学和动力学，并将使用便携式加速计、运动活动日志和经验采样方法来评估手臂在家庭环境中的使用量。我们将确定手臂和手部运动性能的特征，这些特征最能预测手臂在家庭中的重要使用情况。

DESCRIPTION (provided by applicant): Abstract Stroke is the most common cause of chronic disability for adults in the United States, with 65% of individuals after stroke unable to incorporate the hemiparetic upper extremity into daily function. Even mild impairment of upper extremity function after stroke results in significant limitations in daily function and has been demonstrated to negatively impact health-related quality of life. The major objective of this study is to identify the biomechanical variables that predict amount of use of the arm at home. The kinematics and kinetics of the upper extremity during reaching and grasping tasks will be measured in the laboratory and the amount of use of the arm in the home environment will be assessed with portable accelerometry, Motor Activity Log and experience sampling methods. We will identify the characteristics of arm and hand motor performance that best predict significant arm use at home.
