Diagnostic value of electrophysiology in neuromuscular disease in patients with hyperthyroidism

Objective: To investigate the diagnostic value of electrophysiology in neuromuscular disease in patients with hyperthyroidism.Methods: The nerve conduction and lesion condition in patients with hyperthyroidism were detected using electromyograph and needle electrode electromyography(NEMG).The muscle NEMG of different locations was analyzed.Results: The abnormal detection rate of sensory conduction(47.22%) was significantly higher than that of motor conduction(22.22%)(P<0.05).When the proximal muscle slightly contracted,the incidence rate of motor unit potential duration shortening in proximal muscle(58.33%) was higher than that in distal muscle(41.67%)(P<0.05),and the difference of the amplitude decreasing and polyphase wave increasing of muscle motor unit action potential between proximal and distal muscle was not statistically significant in hyperthyroidism patients(P>0.05).Conclusions: The neuromuscular damage in patients with hyperthyroidism can be found,the abnormal sensory conduction is main,and the nerve electrophysiology detection is helpful to clinical diagnosis.
