We present a device for recording and analyzing upper limb movements and muscle activities in a single unit. The device's outputs are related to aspects of clinical assessment such as joint coordination, fatigue and muscle synergies. A comparison with an optoelectronic motion capture system was also carried out during a hand to mouth and a hand to contralateral shoulder task. High correlation was found for the elbow angles, while analysis of the root mean square errors indicated that the angular outputs of the device were overestimated compared to the angles calculated using the optoelectronic system. Biceps and triceps co-contraction patterns were also observed during the hand to mouth task. Applications to the clinical assessment and monitoring of neurological disorders are discussed.
我们展示了一种用于在单个单元中记录和分析上肢运动及肌肉活动的设备。该设备的输出与临床评估的各个方面相关，如关节协调性、疲劳和肌肉协同作用。在一项手到嘴和手到对侧肩部任务期间，还与光电运动捕捉系统进行了比较。发现肘部角度具有高度相关性，而均方根误差分析表明，与使用光电系统计算出的角度相比，该设备的角度输出被高估了。在手到嘴任务期间还观察到肱二头肌和肱三头肌的共同收缩模式。讨论了该设备在神经系统疾病临床评估和监测中的应用。
