Neuro-Muscular Coordination Dynamics in Gait
Objective: Investigate muscle co-activation and firing properties at the motor unit level during different phases of gait.
Results
The toe-off, swing, and heel strike phases of gait marked (pink, blue, yellow, respectively) were identified based on IMU data. The varying patterns of motor unit firing activation across lower limb muscles revealed the modulation in muscle control during different phases of gait.
