尽管多功能假手的可用性不断增加，但用户对这些手的控制和整体功能能力仍然有限。模式识别控制和靶向肌肉神经支配（TMR）手术相结合，这是一种创新技术，将截肢的神经转移到残肢中的新肌肉目标上进行神经支配，已被用于改善上肢近端截肢（即肩关节离断和经肱骨截肢）个体的假肢控制。本研究的目的是确定经桡动脉 TMR 手术后假肢手的抓握控制是否有所改善。八名参与者接受了在肌电模式识别控制下使用多关节假手的培训。所有人都参加了 TMR 手术前后的家庭使用试验。每次家庭试验后都会收集上肢结果测量结果。与术前测量相比，TMR 手术后 9-12 个月，三项结果测量（南安普顿手评估程序、捷成泰勒手功能测试和盒子和块测试）有所改善。上肢截肢者的肌电控制能力评估和活动测量结果测量在手术前后没有差异。离线肌电图分析显示，与 TMR 手术前相比，TMR 手术后握力分类误差有所减少。此外，大多数受试者注意到 TMR 后残肢和幻肢感觉有了质的改善。 TMR 手术可能会导致更多可重复的肌肉收缩，这可能是由于疼痛水平的降低和/或幻肢感觉的变化，可能会增加许多临床上可用的灵巧假手的功能使用。
Despite the growing availability of multifunctional prosthetic hands, users’ control and overall functional abilities with these hands remain limited. The combination of pattern recognition control and targeted muscle reinnervation (TMR) surgery, an innovative technique where amputated nerves are transferred to reinnervate new muscle targets in the residual limb, has been used to improve prosthesis control of individuals with more proximal upper limb amputations (i.e., shoulder disarticulation and transhumeral amputation). The goal of this study was to determine if prosthesis hand grasp control improves following transradial TMR surgery. Eight participants were trained to use a multi-articulating hand prosthesis under myoelectric pattern recognition control. All participated in home usage trials pre- and post-TMR surgery. Upper limb outcome measures were collected following each home trial. Three outcome measures (Southampton Hand Assessment Procedure, Jebsen-Taylor Hand Function Test, and Box and Blocks Test) improved 9–12 months post-TMR surgery compared with pre-surgery measures. The Assessment of Capacity for Myoelectric Control and Activities Measure for Upper Limb Amputees outcome measures had no difference pre- and post-surgery. An offline electromyography analysis showed a decrease in grip classification error post-TMR surgery compared to pre-TMR surgery. Additionally, a majority of subjects noted qualitative improvements in their residual limb and phantom limb sensations post-TMR. The potential for TMR surgery to result in more repeatable muscle contractions, possibly due to the reduction in pain levels and/or changes to phantom limb sensations, may increase functional use of many of the clinically available dexterous prosthetic hands.
