Abstract:
Objective To investigate the electrophysiological of characteristic in patients with sciatic nerve injury induced by intramuscular injection.Methods Needle electromyography(EMG) were performed on the illed lower limb muscles in 104 patients with sciatic nerve injury induced by intramuscular injection. Motor conduction velocity(MCV), distal motor latency(dML), and sensory conduction velocity(SCV) were tested on the common peroneal nerve, tibial nerve and posterior tibial nerve while recording distal compound muscle action potential amplitude(dCMAPA) and sensory nerve action potential amplitude(SNAPA) at the same time.H reflex of the low limb were examed in 21 cases.Results Multiple abnormalities of EMG and NCV were seen 2～7 days after intramuscular injection. The positive rate of NCV tests were higher in common peroneal nerve(68.0%) than in tibial nerve(43.5%)( P
