Résumé
Stroke is the leading cause of acquired motor deficiencies in adults. The restoration of prehension capabilities once in chronic stages of rehabilitation is particularly challenging due to the variability of the user’s needs and the lack of devices available for practical use in daily-life conditions. We investigated the 2-months-long use by 6 chronic stroke survivors in autonomy at home, of a wearable Grasp Neuro-Prosthesis (wGNP). This wGNP allows for user-triggered Functional Electrical Stimulation (FES) of the paretic finger extensors muscles to achieve hand opening. Users could switch at will between two types of grasp (key-pinch or palmar-grasp) and three control modalities (voice control, foot motion and button presses). The daily usage of the device was monitored (median daily usage of 188.4) and self-assessed (median accuracy 85.8%) as well as the preferred modality (Foot motion 4/6). Usage and satisfaction questionnaires were performed (QUEST median score 31/40 and CSQ-8 median score 25/32).
