From: Effect of dance on multi-muscle synergies in older adults: a cross-sectional study
Typical EMG patterns averaged across trials for representative dance and control subjects for the normal stepping (NS; dark line) and perturbation stepping (PS; gray line) conditions, respectively. Time zero (t0) corresponds to the alignment time, which is the time of toe-off. The EMGs were recorded in muscles on the right side of the body. The EMG scales are in arbitrary units and time is in ms (TA tibialis anterior, GM medial head of gastrocnemius, RF rectus femoris, BF biceps femoris)
