Intramuscular TA muscle coherence spectra (10–70 Hz). Session 1. Mean coherence spectra (as defined in the methods section) was calculated during maximal isometric dorsiflexion in the SCI group (n = 20) compared to the non-injured group (n = 15) during the first, and Session 2 last testing session 4 (see data analysis section in the methods). Data is presented as mean and standard error
