The clinical and electrophysiological features of non-inflammatory myopathy with neurogenic lesions / 中国神经精神疾病杂志

ABSTRACT

Objective To investigate the clinical and electrophysiological features of patients with non-inflammatory myopathy with neurogenic lesions. Method The clinical and electromyography data was retrospectively collected from 110 patients who were diagnosed with myopathy and completed routine electromyography examination from 2015 to 2017. A retrospective analysis of clinical and electrophysiological features was conducted on 4 patients with non-inflammatory myopathy with neurogenic lesions. Result Of the 110 patients, 10 patients with neurogenic lesions and 4 of them were diagnosed to have non-inflammatory myopathy. These 4 patients had limb and trunk weakness with muscle atrophy and the electromyography showed neurogenic lesion with or without peripheral nerve lesion. Conclusion This study has revealed neurogenic lesions in a small number of non-inflammatory myopathy on the electromyography, suggesting that the electromyography alone may not be sufficient for diagnosis of myopathy.
