Neurophysiological characterization of spontaneous recovery. a 18 sEMG studies were conducted in the acute/sub-acute phase of SCI, while the majority of studies were conducted during the chronic phase of SCI (mean = 7.33 years). b Spontaneous recovery of sEMG activity from a representative participant. Left: elbow flexor muscles after SCI. Right: averaged response from three 3-s trials recorded from the left and right biceps brachii muscles at 7, 49, 175, and 279 days post-SCI [12] (adapted with permission). ya year, SCI spinal cord injury, AIS American Spinal Injury Association Impairment Scale, RMS root mean square
