Overview
What It Is The PoNS device delivers mild electrical stimulation to the tongue through a mouthpiece while the user performs physical-therapy exercises. The stimulation is intended to enhance neuroplasticity and improve gait and balance. A typical course lasts about 14 weeks with combined in-clinic and home use under therapist supervision.
How It Works Tongue stimulation activates cranial-nerve pathways that connect broadly into brainstem and brain networks involved in balance and motor control. When paired with gait and balance exercises, the stimulation is thought to amplify the plasticity induced by practice—similar in spirit to other paired neuromodulation approaches.
Conditions - FDA-cleared for: gait deficit in mild-to-moderate multiple sclerosis and chronic stroke-related gait impairment (with physical therapy). - Note: Possible tongue or mouth irritation; overall tolerability is good. Coverage is still limited; combined device-plus-therapy cost can be substantial.
How it is administered
Combined in-clinic and at-home use. A mouthpiece delivers mild electrical stimulation to the tongue while you perform physical-therapy exercises. A typical course lasts about 14 weeks under therapist supervision.

This section reproduces the current database's research summary and detail. Structured citation metadata has not been supplied, so it should not be read as an independently verified literature review.
Research summary
Evidence Level: Moderate
What the research shows: Clinical trials supported FDA clearance for improving gait in mild-to-moderate multiple sclerosis and in chronic stroke-related gait impairment when paired with physical therapy.
Key takeaway: A tongue-stimulation device used together with therapy to support balance and walking.
Research detail
Overview The PoNS device delivers mild electrical stimulation to the tongue through a mouthpiece while the user performs physical-therapy exercises. The stimulation is intended to enhance neuroplasticity and improve gait and balance. A typical course lasts approximately 14 weeks and combines in-clinic and home use under the supervision of a trained therapist. The device is FDA-cleared for gait deficit in mild-to-moderate multiple sclerosis and has also received clearance for chronic stroke-related gait impairment.
Evidence Base and Published Work • Clinical trials supported FDA clearance for improving gait in mild-to-moderate multiple sclerosis and in chronic stroke-related gait impairment when the device is paired with physical therapy. • Reviews of cranial-nerve non-invasive neuromodulation for gait provide additional context. • Key published work includes: – Clinical trials supporting FDA clearance for gait deficit in mild-to-moderate MS and chronic stroke-related gait impairment. – Reviews of cranial-nerve non-invasive neuromodulation for gait. – Possible tongue or mouth irritation; overall tolerability is good. Coverage is still limited; cost of device plus therapy is substantial.
Outcomes Outcomes most frequently described include improvements in gait and balance when the device is paired with therapy. Evidence is moderate for the cleared indications.
Questions to ask a provider
1. Do I meet criteria for the PoNS device for gait deficit (e.g., MS or chronic stroke)? 2. What does the 14-week protocol of in-clinic and home use look like? 3. What improvements in gait and balance have been shown when PoNS is paired with physical therapy? 4. What are the side effects (e.g., tongue irritation), and how are they managed? 5. Is the device and associated therapy covered by insurance, and what is the total cost?
