本案例研究报告演示了运动分析与盒子和块测试的修改的使用。目的是量化观察到的代偿运动和同时控制的改善，在使用不同的假肢的受试者在靶向肌肉再神经支配（TMR）手术前后。这是一个单独的案例研究，使用TMR手术前的身体动力假体和6个月后的TMR肌电假体进行数据收集。盒子和块测试被修改为在一个动作捕捉实验室的循环运动。使用TMR肌电假体，受试者能够同时激活手和肘部。任务表现较慢，但肘关节屈曲改善，躯干代偿运动较少。由于没有TMR手术前后肌电性能的直接比较，本病例研究存在一些局限性；然而，目前的报告提出了一种潜在的方法来量化假肢使用者的运动质量和代偿运动。随着进一步的研究，该测试程序有可能成为未来上肢假肢功能标准化评估的有用结果测量方法。
This case study report demonstrates the use of motion analysis with a modification of the Box and Blocks test. The goal was to quantify observed improvements in compensatory movements and simultaneous control in a subject using different prostheses before and after targeted muscle reinnervation (TMR) surgery. This is a single case study with data collection using a body-powered prosthesis pre-TMR surgery and 6 mo postfitting with a TMR myoelectric prosthesis. The Box and Blocks test was modified for cyclical motion within a motion capture laboratory. With the TMR myoelectric prosthesis, the subject was able to simultaneously activate the hand and elbow. Task performance was slower, but there was improved elbow flexion and less trunk compensatory motion than with the body-powered prosthesis. There are several limitations to the case study because there is no direct comparison of myoelectric performance before and after TMR surgery; however, the current report presents a potential method to quantify quality of motion and compensatory movements of prosthetic users. With further study, this test procedure has the potential to be a useful outcome measure for future standardized assessments of upper-limb prosthetic function.
