Eleven patients with static or slowly progressive multiple sclerosis were treated with continuous spinal cord stimulation via epidural electrodes for a minimum of two weeks. An extensive battery of objective tests was used to assess results. Significant improvement in urinary bladder function was seen in 2 of the patients with a lesser degree of improvement in 4 others and reduction of lower limb spasticity in 6 patients. Five additional patients selected for these disabilities were then treated with further evidence of improvement in bladder function in 4 and in lower limb spasticity in 2. It is suggested that benefit results from inhibition of excessive spinal reflex activity.
