Neuromodulation and Dynamic Balance in Stroke

The PoNS group will receive electrical stimulation. Net direct current to the tongue electrode less than 1 µA (micro ampere) will be administered three times a week for four weeks in-lab setting, followed by three times a week for eight weeks at-home setting. Participants will continue to be enrolled in the study for additional 12 weeks without any intervention to evaluate long term effects.

The Sham group will not receive electrical stimulation.

During each session participants will receive gait training exercises for 20 minutes, 20 minutes of balance training exercises, and 20 minutes of breathing exercise three times a week for four weeks in-lab setting. This will be followed by 20 minutes of gait training exercises, 20 minutes of balance training exercises, and 20 minutes of breathing exercise three times a week for eight weeks at-home setting. Participants will continue to be enrolled in the study for additional 12 weeks without any intervention to evaluate long term effects.
