High-Frequency Cervical Spinal Cord Stimulation in Spasticity and Motor Disorders

摘要: High frequency stimulation of the cervical spinal cord was used in an attempt to moderate motor disorders 10 patients, 5 spastics, 3 dystonics and 2 with spasmodic torticollis. Through a C4 flavectomy quadripolar flat electrode introduced into epidural space, placing first terminal at C2. Electrical parameters for were established 0.05-0.10 msec pulse width, rate 200–1,400 Hz amplitude paresthesia threshold. Stimulation delivered 1 hour on off during daytime. Subjective, clinical and/or neurophysiological initial improvement initially observed 9 cases, which system permanently implanted. After mean follow-up 41.4 months all patients but one had condition almost similar prestimulation one.
