Can motor coordination by dynamically controlled? real-time analysis of muscle synergy modulation during walking

Motor control complexity, calculated from muscle synergies, offers a convenient metric to evaluate impairment level in individuals with neuromuscular disorders; however, the role of such measures in rehabilitation remains unclear due, in part, to a limited understanding of the modulability of motor control patterns. In this study, a custom motor control biofeedback system was used to promote user gait pattern exploration to achieve targeted motor control responses. In a three-person pilot population, individuals were able to dynamically alter their motor control complexity away from baseline measures. These results indicate that motor control strategies may be modifiable through rehabilitation and supports the integration of such metrics into clinical practice.
