Official Title: Direction Modulation of Muscle Synergies After a Stroke
Brief Summary: The aim of the study is to investigate the capacity of post-stroke individual (study group) to modulate their EMG muscle activation pattern (MAP) compared to healthy individuals (control group), and to correlate these capacities with their motor impairments. Twenty post-stroke individuals and 12 healthy individuals will participate in this study. each participant will carry out hand-reaching movements in multiple directions, monitored by an EMG device. The modulation of the EMG signal will be compared between groups in terms of EMG-MAP and in terms of muscle-synergies. Additionally the MAPs and synergies of the study group will be correlated with their Fugl-Meyer (FM) assessment scores. Analysis of the muscle synergies underlying the EMG signal will be carried out by the Non-negative Matrix Factorization (NMF) algorithm.
