Cervical dystonia (spasmodic torticollis) is a focal dystonia of the cervical region. Various treatment modalities have been performed with variable success rates. We present a 42-year-old woman complaining of involuntary head rotation for the last 3 years. Different medical treatments had been used for 3 years. Botulinum toxin injections resulted in temporary and moderate improvement for periods of 3–4 months. Pallidal stimulation was performed using a quadripolar electrode and a battery-operated programmable pulse generator. We conclude that a unilateral pallidal lesion or stimulation is an effective method of treatment in focal dystonia. The target must be the pallidum contralateral to the contracted sternocloidomastoid muscle. Deep brain stimulation is superior to lesioning because of the capability of manipulating the stimulation parameters which can modify the pallidotomy effect.

Electrical root stimulation revealed more abnormalities in patients with LSS in comparison with needle EMG. However, both methods seemed to complement each other to show additional pathology in a given patient.

If there was no significant difference in all the electrophysiological parameters, the increase in turn-amplitude analysis in the group of subvastus approach would be considered as an indicator of a faster functional improvement of knee extensor mechanism in these cases.
