The Study of Diagnostic Efficacy of Nerve Conduction Study Parameters in Cervical Radiculopathy Keywords: Conduction velocity, Sensitivity, Specificity

IntrOductIOn Cervical Radiculopathy (CR) is a neurologic condition characterised by dysfunction of a cervical spinal nerve, the roots of the nerve, or both [1]. It is a clinical diagnosis based on a sclerotomal distribution of motor and/or sensory changes or complaints. Any process that causes impingement of exiting cervical nerve roots can lead to a radicular disorder. Impingement may be brought about by acute pathologic changes or by degenerative changes consistent with cervical spondylosis. Retropulsed disk material, zygoapophyseal joint hypertrophy, neurocentral joint hypertrophy, and other softtissue abnormalities all may cause compression of an exiting nerve root. The reported annual incidence rate of CR is 107.3 per 100,000 for men and 63.5 per 100,000 for women, with a peak at 50 to 54 years of age [2]. Cervical spondylosis is considered as the most common cause of cervical radiculopathy (in 70 to 75 percent of cases).
