Online Continuous Detection of Time-Varying Muscle Synergies

Muscle synergies have been widely used as a compact description of the neuromuscular motor control strategies. The online detection of synergistic activations might therefore improve the feasibility of sEMG-based control algorithms. In this study, a simple online detector of time-varying muscle synergies activation timings is proposed, and its performance is evaluated in a simulated online scenario on a small sample of experimental signals.
