Radiculopathy is a mechanical compression of a nerve root usually at the exit foramen or lateral recess. Cervical radiculopathies (CR) was conditions involving a pathological process affecting at or near the root of the nerve, shortly after its exit from the upper back spine. The pain or other symptoms often radiate to the part of the body served by that nerve, if a nerve root impingement involved in the neck can produce pain and weakness in the forearm. Aim of present study to evaluate diagnostic utility of nerve conduction studies in cervical radiculitis/radiculopathy. Thirty five patients with unilateral cervical radiculopathy, confirmed by clinical and magnetic resonance imaging (MRI) evidences were studied. Selected patients were divided in two groups GROUP A- Asymptomatic side in subject clinically diagnosed with radiculitis/radiculopathy is used as control group. GROUP B- Symptomatic side in same subjects clinically diagnosed with radiculitis/radiculopathy used as case group. A high-voltage electrical stimulator was used to elicit nerve response bilaterally at various stimulation sites for the diagnosis of cervical nerve-root radiculopathy. The reduced CMAP of median had shown significant variation on symptomatic side as compare to asymptomatic side. These variations in side to side nerve conduction parameters by non-invasive technique brings awareness to clinicians about the radiculopathy and this report may also be useful to clinician for early diagnosis of cervical radiculopathy.
