Summary

This is a pilot, single blind, randomized, sham-controlled trial to assess the benefit of Percutaneous Tibial Nerve Stimulation (PTNS) in treating bladder overactivity (OAB) symptoms in multiple sclerosis (MS) patients. The data generated by this study would provide support for a future multi-institutional, randomized prospective trial.

Conditions

Interventions

DEVICE

PTNS Treatment

Patients will be placed in a comfortable position, sitting or supine. The treatment leg will be propped up comfortably on a footrest but draped and out of view from the patient. A 34-gauge needle electrode will be inserted at a 60-degree angle 5 cm cephalad to the medial malleolus and slightly posterior to the tibia. A PTNS surface electrode will be placed on the ipsilateral calcaneus as well as 2 inactive sham surface electrodes, 1 under the little toe and 1 on the top of the foot. When the PTNS lead set is connected to the Urgent PC stimulator, a current level of 0.5 to 9 mA at 20 Hz is selected based on each patient's foot and plantar motor and sensory responses. Treatment lasts 30 minutes and given once weekly for 12 consecutive weeks.

DEVICE

Sham PTNS Treatment

Patients will be positioned similarly as PTNS patients. A Streitberger needle will be used at the tibial nerve insertion site as described above to simulate needle placement. Three electrodes will be placed on the patient's foot, two active TENS electrodes and one inactive TENS electrode. The TENS "grounding pad" will be a gel electrode pad from a TENS unit device that is placed on the bottom of the foot just below the smallest toe. Another gel electrode will be placed on the top of the foot just above the small toe for conduction. These two electrodes will be connected to the TENS unit lead wires for sham stimulation. A third, inactive, gel electrode, will be placed near the medial aspect of the calcaneus to mimic the PTNS treatment. The TENS electrode will be connected by lead wires to the TENS unit set at 20 HZ. The TENS unit will be turned on and stimulation slowly increased to the patient's first sensory level and then turned off.
