Description
Inclusion Criteria:
INDIVIDUALS WHO HAVE HAD A STROKE:
- Diagnosis of first ever stroke
- At least 6 months after stroke onset
- Motor-evoked potentials in hand/arm muscles
Subjects must show an understanding of the study goals and have the ability to follow simple directions as judged by the investigators.
ALL INDIVIDUALS:
- Between the ages of 18 and 75 years old
Exclusion Criteria:
INDIVIDUALS WHO HAVE HAD A STROKE:
Hemispatial neglect, aphasia, or cognitive impairment that would impact testing and would interfere with the ability to follow simple instructions, as judged by the investigators
ALL INDIVIDUALS:
- Neurological disorder(s) influencing movement (besides stroke)
- History of seizure or epilepsy
- Metallic brain implants
- Bodily implants such as cardioverter defibrillators, insulin pumps, ventriculoperitoneal shunts, cochlear implants, or pacemakers
- Pregnant or expecting to become pregnant
- Difficulty maintaining alertness and/or remaining still
- Silicone or plastic allergy
- History of vestibular disorders (eg, Vertigo, Meniere's Disease, etc.)

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: PAS+VNS
Paired-associative stimulation (PAS) targeting primary motor cortex will be administered with VNS in individuals with hemiparesis secondary to stroke and neurologically-intact, age-matched controls.
|
Simultaneous activation of connections in motor cortex via stimulation to the nerves and brain.
Other Names:
Recruits the auricular branch of the vagus nerve which activates brain structures that release chemicals mediating cortical plasticity.
Other Names:
|
Sham Comparator: PAS+Sham
Paired-associative stimulation (PAS) targeting primary motor cortex will be administered with sham stimulation in individuals with hemiparesis secondary to stroke and neurologically-intact, age-matched controls.
|
Simultaneous activation of connections in motor cortex via stimulation to the nerves and brain.
Other Names:
Sub-threshold stimulation that does not activate neural structures.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in size of evoked potential
Time Frame: 1 week
|
The primary endpoint is the change from baseline (ie, before PAS) in the size of evoked potentials.
Differences in the change between conditions (ie, PAS+VNS vs PAS+Sham) will address whether VNS drives cortical plasticity.
