Study Arms (1)

4-week TTNS home based protocol

EXPERIMENTAL

Transcutaneous Tibial Nerve Stimulation (TTNS) applied to subjects for 4-week protocol.

Device: 4-week TTNS home-based protocol

Interventions

4-week TTNS home-based protocol. Electrodes 2 inch by 2 inch will be placed according to anatomic landmarks, with the negative electrode behind the internal malleolus and the positive electrode 10cm superior to the negative electrode, verified with rhythmic flexion of the toes secondary to stimulation of the flexor digitorum and hallicus brevis. The intensity level will be set to the amperage immediately under the threshold for motor contraction. If there is not contraction seen, maximal tolerable intensity will be used. In addition, if the patient perceives pain, the intensity will be lowered until comfortable. Stimulation frequency of 10 Hz and pulse width of 200ms in continuous mode will be used.

4-week TTNS home based protocol
