Results from intercostal electromyography examination of five sensorimotor complete thoracic SCI patients. Sensory levels are indicated. Some segments showed a mixed pattern (^*). Same letters assigned as in Figure 4. Patient (a) showed two full segments of denervation activity before spastically activated normal motor unit potential (MUP) reappeared below the lesion. Patient (b) had voluntarily activated large-amplitude MUP just adjacent to the lesion interpreted as a reinnervated root injury, and an asymmetrical reappearance of spastically activated normal MUP, totaling 2.25 denervated segments. Patient (c) showed no denervated segment. Patient (d) had an asymmetrical injury translated to 0.75 denervated segments, in one segment below the lesion spastically activated large amplitude MUP were found interpreted as an earlier root injury. Patient (e) presented with one unilateral segment showing a mixed pattern of voluntarily activated MUP and denervation activity, 0.25 denervated segments in total.
