Figure 5: Electromyographic assessment demonstrating reinnervation of the denervated muscles. (A1) At 9 weeks after transfer, many positive sharp waves were observed (P > 0.05). (A2) Muscular action potentials began to appear and positive sharp waves disappeared. (A3) Numerous muscular action potentials were detected (P > 0.05). (B) The reinnervated potentials were prominently detected in the QF, moderately detected in the SM and QC, and slightly detected in the TA (P > 0.05). (C) H-reflex was evoked in a naïve rat as a control. At 9, 13, and 17 weeks after transfer, the H-reflex was markedly elicited in the gastrocnemius of the affected hindlimb, the latency of which shortened over time and reached an approximately normal latency. GC: gastrocnemius; QF: quadriceps femoris; SM: semimembranosus; TA: tibialis anterior.
