目的：肌电手训练对截肢者操作假肢能力的影响尚未得到充分验证。本研究旨在探讨单手和双手任务对截肢者在训练中使用肌电假手能力的影响。方法：受试者为单侧经桡动脉截肢者（n = 12）。通过将肌电手假肢使用者分为两组并进行交叉研究来测量每项任务的训练效果：一组先执行单手任务，然后执行双手任务，另一组则执行相反的操作。采用南安普顿手评估程序（SHAP）评分来评估受试者控制肌电假手的能力。结果：单手任务SHAP评分：6.3（5.8-8.5）分和双手任务SHAP评分：10.3（8.8-14.2）分之间训练效果存在显着差异；然而，效果还不够（p=0.008，r=0.20）。结论：双手任务比单手任务更有效地提高了受试者准确操作肌电手的能力。这表明双手任务在开发肌电手对打开/关闭运动和物体处理的控制方面比单手任务更有效。
Objective: The influence of myoelectric hand training on the ability of amputees to operate a prosthetic hand has not been fully verified. This study aimed to investigate the effects of single-handed and dual-handed tasks on the ability of amputees to use a myoelectric prosthetic hand in training.Method: The subjects were unilateral transradial amputees (n= 12). The training effects of each task were measured by assigning the myoelectric hand prosthesis users to two groups and conducting a crossover study: one group performed the single-handed task first followed by the dual-handed task, and the other group did the opposite. The Southampton Hand Assessment Procedure (SHAP) score was used to assess the subjects' ability to control the myoelectric prosthetic hand.Results: The training effect differed significantly between the single-handed task, SHAP score: 6.3 (5.8-8.5) points, and the dual-handed task, SHAP score: 10.3 (8.8-14.2) points; however, the effect was insufficient (p= 0.008, r= 0.20).Conclusion: The dual-handed task improved the subjects' ability to accurately operate a myoelectric hand more effectively than the single-handed task. This suggests that the dual-handed task is more effective at developing control of opening/closing movements and object handling with a myoelectric hand than the single-handed task.
