Fig. 1: EMG activity of leg muscles during stepping.

From: Complexity of modular neuromuscular control increases and variability decreases during human locomotor development

Fig. 1

a Raw EMG data from eight bilateral leg muscles (gray) in one representative neonate. Black lines represent the rectified EMG data, red lines represent the reconstructed EMG data using spatial decomposition with two modules. b Raw EMG data in one representative adult (same format as a). Red lines represent the reconstructed EMG data using spatial decomposition with four modules. Red areas highlight an example of the different inter-muscular coordination (synchronous in the neonate vs. asynchronous in the adult) of some groups of muscles.
