From: Effect of dance on multi-muscle synergies in older adults: a cross-sectional study
Onsets of EMG activity averaged across subjects, plotted for the normal stepping (NS) and perturbation stepping (PS) conditions in the dance and control groups. Onset of muscle activation is plotted in ms and the mean ± SD is shown (TA tibialis anterior, SOL soleus, GL lateral head of gastrocnemius, GM medial head of gastrocnemius, RF rectus femoris, VL vastus lateralis, VM vastus medialis, BF biceps femoris, ST semitendinosus, RA rectus abdominis, ES erector spinae). The asterisks ‘*’ indicate statistical significance
