EMG and MEPs to the Paraspinal Muscles i In Cervical Sportdylosis

Abstract

Cervical spondylosis is a degenerative disease of the ce1vical spine that affects all levels of cervical spines, commonly after middle 'age. Neurophysiological assessment of paraspinal muscles aid in the early detection of pathological abnormalities. The aim of this work is to assess the EMG and MEPs findings in PM in cervical spondylotic radiculopathy with or without myelopathy and to assess the sensitivity of examination of these muscles in relation to limb :muscles EMG and MEPs. 25 patients with cervical spondylotic radiculopathy with and without myelopathy with age ranging from 27 years to 55 years with a mean of 43.5 years and they were compared to ten normal control subjects age and sex matched. The results showed that EMG sensitivity test was higher in PM muscles and the most prominent abnormalities were signs of denervation. The percentage of abnormalities of cortical absolute latency to PMs was highly significant than of limb muscles and for PMC7 than to PMC5. We concluded that abnormalities in PM

EMG and MEPs examinations are sensitive in localizing that the lesion whether I I • after or proximal to the roots. i
