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.
