An Early Phase 1 interventional study of Transcutaneous Electrical Stimulation in Healthy Volunteers, Spinal Cord Injury and Stroke, sponsored by Northwell Health. Recruiting at 1 site in United States. Open to participants aged 18 Years to 75 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-03-11.
Sponsored by Northwell Health · Early Phase 1, Interventional, and Device feasibility
This is an early feasibility trial to determine whether transcutaneous neuromuscular electrical stimulation, with or without transcutaneous spinal cord stimulation, using an investigational neurostimulation device improves functional arm/hand movements in individuals with paralysis or paresis due to a spinal cord injury or stroke and improves functional arm/hand or leg/foot movements in individuals with paralysis or paresis due to other brain or nerve injuries.
In this study, eligible individuals that agree to participate will be asked to attend up to 5 study sessions a week for 1 year (depending on participant availability), with each session lasting up to 4 hours. At the first study session, participants will have their demographic information collected, vital signs assessed, and have measurements performed of their limbs and torso, as appropriate. They will also undergo clinical evaluations and tests to assess their current functional movement and sensation capabilities.
During subsequent study sessions, participants will undergo many tasks designed to improve functional movements in paralyzed limbs. Specifically, participants will receive neuromuscular electrical stimulation to the limb(s) and/or electrical stimulation to the spinal cord to evoke specified movements. The stimulation parameters and locations on the spinal column and/or limb(s) that evoke specific movements will be noted. The movements will be assessed with visual inspection, electromyography, and/or sensors.
The clinical evaluations and tests to assess functional movement and sensation capabilities will be repeated throughout the study and at the last study session to assess for functional improvements compared to the first study session. Upon completion of these study sessions, the individual's participation in the study is considered complete.
During study sessions, both neuromuscular and spinal cord stimulation will first be manually administered to properly map the area in relation to intended movements. Once mapping for placement is completed, the study team will proceed with administering electrical stimulation with the investigational stimulator to evoke specific movements. In order to facilitate the connectivity of these electrodes with the skin, electroconductive gels, lotions, creams, and sold hydrogels may be used.
The improvement of the precision, specificity, and extent of functional movements over the course of focused electrical stimulation sessions for various electrical stimulation amplitudes at key locations will be assessed visually and through electromyography. The grip strength and evoked pressures at the limbs will also be measured using sensors placed at those locations. The specificity and quantification of the various movements will be assessed with a motion tracking device as well.
The study will use the following clinical tests and graded tasks, as needed, to assess changes in functional movement over time: Range of Movement Evaluation; Spasticity Reduction Evaluation; Sensory Perception Evaluation; Graded Redefined Assessment of Strength, Sensibility, and Prehension; Jebsen-Taylor Test; Action Research Arm Test; Chedoke Arm and Hand Activity Inventory; Chedoke-McMaster Stroke Scale; Wolf Motor Function Test; Just Noticeable Weight Test; Grip Strength / Finger Strength Assessments; Fugl-Meyer Assessment; Stroke Rehabilitation Assessment of Movement; and Object Transfer Tests (including 9-Hole Peg \& Cup/Cone/Ball Transfer). All of these tests and exams have been validated, and involve participants performing simple movement tasks or identifying a physical sensation.

This arm consists of healthy volunteers receiving transcutaneous electrical stimulation to the arms, legs, and/or spinal column to evoke various arm/hand and leg/foot movements.
Device: Transcutaneous Electrical Stimulation
This arm consists of individuals with a spinal cord injury receiving transcutaneous electrical stimulation to the arms/hand and/or spinal column to evoke various arm/hand movements.
Device: Transcutaneous Electrical Stimulation
This arm consists of individuals with a stroke receiving transcutaneous electrical stimulation to the arms/hand and/or spinal column to evoke various arm/hand movements.
Device: Transcutaneous Electrical Stimulation
This arm consists of individuals with a other brain and nerve injuries receiving transcutaneous electrical stimulation to the arms/hand, legs/foot, and/or spinal column to evoke various arm/hand or leg/foot movements.
Device: Transcutaneous Electrical Stimulation
The study involves the administration of various electrical pulses being delivered to muscles and/or the spinal column with an investigational neurostimulator to evoke various limb movements in order to improve functional movement.
Device Feasibility for Changing Muscle Activation of the Arm and Hand
The primary outcome will be measured as the ability for the neurostimulation device to elicit changes in muscle activation (measured by electromyography) of the arm and hand of individuals with a spinal cord injury or stroke from baseline (prior to study intervention) until study completion (after initiation of study intervention).
Time frame: 12 months
Change in Muscle Activation of the Targeted Limbs
The exploratory outcome will be measured as the change in muscle activation (measured by electromyography) of the targeted limbs of individuals with other brain or neurological injuries from baseline (prior to study intervention) until study completion (after initiation of study intervention).
Time frame: 12 months
Plan to share: Yes — The identifiable information collected on this study will only be shared with other researchers that have obtained approval from the institutional review board (IRB). After a request for study information is received, the principal investigator (Chad Bouton, MS) will determine whether the requested information can be shared given the authorization status of the study participants. After approval by the principal investigator, the researcher will be required to present a letter indicating IRB approval of their study and a copy of the approved protocol indicating that approval includes the receipt of information from this study. If this information is obtained, the principal investigator will provide the requested information (taking into account the authorization status of participants) to the researchers in a HIPAA-compliant manner.
Supporting information: Statistical analysis plan, Informed consent form
Time frame: The study will only provide identifiable information pertaining to participants as long as there is active and valid IRB approval of the study. After the study is completed and the study has been closed with the IRB, information will no longer be shared.
Access criteria: The study will only share information with other researchers that have been approved by the principal investigator (Chad Bouton, MS), have showed evidence that their study has valid IRB approval that includes the ability to receive the requested information, and has provided a copy of the approved protocol to verify they can receive the requested information and that the information will be stored in a HIPAA-compliant manner.
