Abstract

The purpose of this study was to determine whether subjects with abnormal EMG were more likely to have abnormal MRI findings of cervical spine than those with normal EMG. Between January 2011 and May 2014. Eighty five patients referred to the  department of Hilla teaching hospital  with  shoulder pain  underwent  EMG and MRI of cervical spine. Two groups were chosen for the MRI study: the first group (n=35) consisted of the normal EMG while the second group (n=50) comprised those with abnormal. The degrees of disc degeneration, anular tear, disc herniation and protrusion were assessed by two radiologists. The differences between the two study groups were evaluated. Eighty five patients do EMG of upper limb, finding 35 patient with normal EMG(NEMG) and 50 patient with abnormal EMG (AEMG). Altogether, 510 discs were analyzed on the MR images (210 discs for patients with NEMG  and 300 discs for patients with AEMG ). No MR image was excluded due to inadequate visibility or artifacts. The study found that abnormal MRI findings were common in both study groups. Disc herniation was the only MRI finding that was significantly associated with abnormal EMG.
