A Study Of Vagus Nerve Stimulation (VNS) With Mobility Training For Gait Recovery After Chronic Ischemic Stroke

Purpose

The purpose of this study is to evaluate the safety, feasibility, and efficacy of vagus nerve stimulation (VNS) paired with mobility training to improve lower extremity function and gait in individuals with chronic ischemic stroke.

Condition

  • Ischemic Stroke

Eligibility

Eligible Ages
Over 18 Years
Eligible Sex
All
Accepts Healthy Volunteers
No

Inclusion Criteria

  • Age ≥ 18 years - Ischemic stroke ≥6 months prior to enrollment. - Post-stroke lower extremity impairment defined as gait velocity of less than 0.8 m/s on a 10-meter walk test - Provision of informed consent

Exclusion Criteria

  • Intracerebral Hemorrhage - Active or prior psychosis or substance abuse within two years. - Pre-stroke modified Rankin Scale (mRS) 3-5. - Unable to participate in in-clinic rehabilitation. - Preexisting neurological disorders affecting gait and mobility, such as Parkinson's disease, Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), dementia, major head trauma.

Chronic ischemic stroke
Participants with chronic ischemic stroke will be treated with a combination of vagus nerve stimulation and mobility training.
  • Other: Vagus nerve stimulation (VNS) paired with mobility training
    Participants will complete a 6-week in-clinic therapy phase (3 sessions per week), where a physical therapist will lead mobility training with VNS delivered via a handheld magnet. This will be followed by a 6-week at-home phase where participants continue daily exercises and VNS use, supported by weekly video calls to review at home rehabilitation activity and wearable activity monitors for remote monitoring.
