ABSTRACT

Objective To investigate the electromyographic(EMG)characteristics of sternocleidomastoid muscle in patients with motor neuron disease.Methods The clinical and EMG data of 461 patients of MND group and 349 of non-MND group were analyzed retrospectively.Results The abnormality rate of sternocleidomastoid EMG in MND group was 60.3%,much higher than that in non-MND group(4.6%)(P
