We studied cervical root stimulation technique in 10 patients with clinical symptoms and signs of unilateral cervical radiculopathy, stimulation of nerve root was done with monopolar needle in paraspinal muscle 1.5cm lateral from and level of spinous process of cervical verebra, Recording of CMAP was done by surface electrodes on biceps brachii, triceps brachii, abductor digiti minimi, We concluded as follow:

1) Cevical root stimulation technique is accurate, reproducible and safe electrodiagnostic method.

2) Cevical root stimulation technique helps to detect cervical radiculopathy especially when needle EMG does not show definite denervation evidence; as in acute stage of radiculopathy less than 4 weeks after symptom and in chronic stage with repeated denervation and reinnervation.

Key Words: Root stimulation, Cervical radiculopathy
