Abstract — This work explores the functional and psychosocial impact of the multigrip Michelangelo (M) prosthetic hand. Transradial myoelectric prosthesis users (6 men, median age: 47 y) participated in a crossover longitudinal study. A multifactorial assessment protocol was applied before the application of M and after 3 mo (functional assessment) and 6 mo (psychosocial assessment) of home use. Functional assessment included both practical tests (i.e., Southampton Hand Assessment Procedure [SHAP], Box and Blocks Test [BBT], and Minnesota Manual Dexterity Test [MMDT]) and self-report functional scales. Psychosocial assessment consisted of a clinical interview and a battery of self-report questionnaires concerning current anxious-depressive symptoms and health-related quality of life, body image concerns, adjustment and satisfaction with prosthesis, social support, coping style, and personality. Increased manual dexterity was observed after 3 mo based on improvements in the SHAP, BBT, and MMDT. Two important themes emerged from the clinical interviews at the 6 mo follow-up: (1) the enhanced functionality and (2) the "like a real hand" aspect of the M, which further increased prosthesis integration to the Self. A few patients expressed concerns about M dimension, noise, and weight. The M appeared to restore hand function and natural appearance. The present findings provide preliminary evidence, and additional studies are needed.

Key words: amputation, crossover study, functional assessment, longitudinal design, manual dexterity, multidisciplinary approach, prosthesis, psychosocial assessment, technology assessment, upper limb.
