Cervical electrical stimulation evokes a potential in the muscle innervated by the cervical and brachial plexuses. We present 2 cases of herniated cervical intervertebral disc which illustrate the usefulness of motor stimulation to localize a motor radicular lesion. The simultaneous recording of several muscles innervated by different radicular levels has enabled us to demonstrate the exact level and side of the lesion. Cervical motor tract stimulation is a good means of diagnosing a radicular lesion when peripheral nerve conduction velocities are normal.
