目的：以往的研究表明，急性脑卒中患者可记录的握力恢复是早期上肢恢复最敏感的评估之一，也是后期恢复的良好预后因素。本研究的目的是检验最大自主握力（MVGF）测量的可靠性，并评估双亲握力缺陷与双亲上肢功能之间的关系。设计：在三周的时间内，对15名慢性卒中患者和10名对照患者的双侧MVGF进行了三次改良应变计测力计评估。父母的MVGF缺陷与未受影响的手的MVGF有关。结果测量：采用Fugl-Meyer、老年人上肢功能测试（TEMPA）、Box和Block以及指鼻测试来测量卒中受试者的上肢功能。结果：两组受试者的MVGF测量具有良好的信度（类内相关性，ICC >0.86）和低标准误差测量（SEM）。与对照组相比，中风患者的双亲MVGF明显受损。线性和二次回归分析的结果表明，这种损害显著相关(p
Objectives: Previous studies have shown that recovery of recordable grip strength in acute stroke subjects is one of the most sensitive assessments of initial upper limb recovery and a good prognostic factor for latter recovery. The objectives of this study were to test the reliability of maximal voluntary grip force (MVGF) measures and evaluate the relationship between paretic grip strength deficit and paretic upper extremity function in chronic stroke subjects.Design: Over a three-week period, bilateral MVGF was assessed three times with a modified strain gauge dynamometer in 15 chronic stroke subjects and 10 control subjects. The paretic MVGF deficit was expressed in relation to the MVGF of the nonaffected hand.Outcome measures: Upper extremity function in stroke subjects was measured using the Fugl-Meyer, the upper extremity performance test for the elderly (TEMPA), Box and Block and finger-to-nose tests.Results: MVGF measures in both groups of subjects demonstrated good reliability (intraclass correlation, ICC >0.86) and low standard error measurements (SEM). The paretic MVGF of the stroke subjects was greatly impaired in comparison to the control subjects. Results of linear and quadratic regressions analyses show that this impairment was significantly correlated (p
