The multi-grip and standard myoelectric hand prosthesis compared: Does the multi-grip hand live up to its promise?

Multi-grip myoelectric hand prostheses (MHPs) have five movable and jointed fingers and aim to increase functionality. However, literature comparing the MHP with the standard myoelectric hand prosthesis (SHP) is limited and inconclusive. Therefore, the MHP and SHP were compared with each other on the different domains of the International Classification of Functioning, Disability, and Health-model (ICF-model). A total of 14 MHP users performed the refined clothespin relocation test, tray-test, Box and Blocks Test and the Southampton Hand Assessment Procedure with their MHP and an SHP (i.e., within-group comparison). Additionally, the 14 MHP and an additional group of 19 SHP users completed the following questionnaires: Orthotics and Prosthetics Users' Survey - The Upper Extremity Functional Status Survey, Trinity Amputation and Prosthesis Experience Scales for upper extremity, Research and Development-36, EQ-5D-5L, visual analogue scale, Dutch version of the Quebec User Evaluation of Satisfaction with assistive technology and the patient-reported outcome measure to assess the preferred usage features of upper limb prostheses (i.e., between-group comparison). All 14 MHP users and 16 out of 19 SHP users provided an informed consent for reuse of their data in future research. This data can be requested for research purposes.
