中风后，许多人“不能也不”使用他们的瘫痪上肢。随着恢复，有些人“可以，但不”使用他们的瘫痪上肢，这种不使用应抵消具体rehabilitation.The研究的目的是量化的一个方面的不使用：近端臂不使用时达到一个人的手臂长度在45中风后和45年龄匹配的控制。手臂使用是指肩部和肘部运动对朝向目标的手部运动的贡献。近端手臂不使用的计算方法为自发手臂使用与最大手臂使用之间的比值。我们发现近端手臂不使用具有非常好的重测信度，不依赖于卒中后的时间，随着损伤的增加而增加（Fugl-Meyer）和功能丧失（Box & Block），最重要的是，61%的轻度损伤患者（Fugl-Meyer >28/42）显示近端臂不使用。中风个体提供了补充常规临床测量的新信息。近端手臂不使用可能量化了运动储备的一个方面，治疗师可以在患者特定的康复计划中针对该方面。(C)2017爱思唯尔B.

After a stroke, many people "cannot and do not" use their paretic upper limb. With recovery, some people "can but do not" use their paretic upper limb and this non-use should be counteracted with specific rehabilitation.The aim of the study was to quantify one aspect of the non-use: proximal arm non-use when reaching within one's arm length in 45 post-stroke and 45 age matched controls. Arm use refers to the contribution of the shoulder and elbow motion to the hand movement towards the target. Proximal arm non-use is calculated as the ratio of the difference between spontaneous arm use and maximal arm use.We found that proximal arm non-use has very good test-retest reliability, does not depend on time since stroke, increases with impairment (Fugl-Meyer) and loss of function (Box & Block), and most importantly, that 61% of patients with lower impairment (Fugl-Meyer >28/42) exhibit proximal arm non-use.We conclude that quantifying proximal arm non-use in post-stroke individuals provides novel information that complements routine clinical measures. It is likely that proximal arm non-use quantifies one aspect of the motor reserve that therapists can target in patient specific rehabilitation programs. (C) 2017 Elsevier B.V. All rights reserved.
