Abstract

Background: Clinical evidence substantiating the advantages multi-grip myoelectric hand prosthesis over conventional myoelectric hand prosthesis in daily life remains inconclusive.

Objectives: The study aimed to assess the efficacy of using a multi-grip myoelectric hand prosthesis after utilizing a conventional myoelectric hand prosthesis.

Study design: A before-and-after, multi-center, observational study included adults with complete hand amputation using a standard myoelectric hand prosthesis for more than 4 weeks.

Methods: Patients were assessed at T0 with their standard myoelectric hand prosthesis, after a 4 to 6 weeks training and trial period with a multi-grip myoelectric hand prosthesis (T1) and then after an 8 to 10 weeks period of wearing (T2). The primary outcome measure was the change of upper limb function via the Orthotics and Prosthetics Users' Survey (OPUS). Results: twenty-two participants were prescribed a definitive multi-grip hand myoelectric prosthesis. On average, the duration since amputation was 6.5 ± 11.4 years. Traumatic causes accounted for 77.3% (17/22) of the cases. The upper limb function component score of the OPUS exhibited a mean increase of 6.2 ± 10.8 points (95% CI 1.5 to 11.0) from T0 to T2. Statistically significant improvements were also noted in the quality-of-life component of OPUS, the Quick DASH score, and overall satisfaction with prosthesis.

Conclusions: In this study, the transition from using daily living standard myoelectric hand prosthesis to using a multi-grip myoelectric hand prosthesis yielded improvements in functionality, quality of life, and overall satisfaction (self-drafted) among individuals with complete hand amputation.

全手截肢患者在使用标准肌电义肢后使用多握力肌电义肢的观察性研究。

背景：在日常生活中，多握点肌电手假体优于常规肌电手假体的临床证据尚不明确。目的：本研究旨在评估在使用常规肌电假肢后使用多握点肌电假肢的效果。研究设计：一项前后、多中心、观察性研究，包括使用标准肌电假肢进行全手截肢4周以上的成年人。方法：患者在T0时使用标准肌电手假体进行评估，经过4 ~ 6周的多握柄肌电手假体训练和试用期（T1），再经过8 ~ 10周的佩戴期（T2）。主要结局指标是通过矫形和假肢使用者调查（OPUS）测量上肢功能的变化。结果：22名参与者被规定了明确的多握力手肌电假体。截肢后的平均时间为6.5±11.4年。创伤原因占77.3%（17/22）。从T0到T2， OPUS上肢功能成分评分平均增加6.2±10.8分（95% CI 1.5 ~ 11.0）。在OPUS的生活质量组成部分、快速DASH评分和对假体的总体满意度方面也有统计学上显著的改善。结论：在本研究中，从使用日常生活标准的肌电假肢过渡到使用多握点的肌电假肢，可以改善完全截肢患者的功能、生活质量和总体满意度（自评）。
