Brief Summary:

The specific aim of this study is to evoke functional movement in the hand of both healthy individuals and individuals diagnosed with a complete (AIS "A") C5 level spinal cord injury. The primary purpose of this study is to determine the feasibility of achieving refined hand movements through electrical stimulation of the muscles within the forearm. It is believed that this study will be able to identify specific stimulation parameters and electrode spatial configurations responsible for various refined hand movements.

After an eligible individual agrees to participate in this study, s/he will receive transcutaneous electrical stimulation on the forearm in order to evoke different hand and finger movements. The precision, specificity, and extent of these movements will be visually assessed. In order to better evaluate these movements, participants may also be asked to perform various functional tasks with their hand. The grip strength and evoked forces at the fingertips will also be measured using sensors. There will be up to 4 study sessions each week for up to 8 weeks, with each session lasting up to 4 hours. Upon completion of these study sessions, the individual's participation in the study is considered complete.

Healthy Volunteers Spinal Cord Injury Cervical Spinal Cord Injury at C5 Level Spinal Cord Injury at C5-C7 Level Physical and Rehabilitation Medicine Device: Participants will receive neuromuscular electrical stimulation via an investigational (not FDA approved) neuromuscular stimulator. Early Phase 1

Detailed Description:

In order to evaluate whether electrical stimulation applied to the muscles within the forearm can evoke functional movement in the hand, participants will receive transcutaneous electrical stimulation via an investigational (not FDA approved) neuromuscular stimulator.

Participants will be asked to attend up to 4 study sessions a week for up to 8 weeks, with each session lasting up to 4 hours. At these sessions, electrical pulses will be sent to the forearm muscles through electrodes placed on the skin. These electrodes may also be accompanied with a gel or lotion to allow for a better connection of the electrodes to the skin. The precision, specificity, and extent of hand and finger movements will be visually assessed in real time and later reassessed on video recordings of the session. The study will also involve the placement of sensors on the hand and finger to measure the amount of grip strength and evoked forces. In order to monitor the health of participants, the study will assess blood pressure and heart rate before, during, and after the electrical stimulation. Upon completion of these study sessions, the individual's participation in the study is considered complete.


Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 15 participants
Allocation: Non-Randomized
Intervention Model: Sequential Assignment
Intervention Model Description: The study will involve 3-10 eligible healthy volunteers and 2-5 eligible individuals with a traumatic spinal cord injury. The study will first enroll healthy volunteers into the study in order to determine the feasibility of evoking refined hand movements through electrical stimulation, and determine the electrical stimulation parameters and electrode spatial configurations responsible for various hand movements. After this is done, the study will proceed with the enrollment of individuals with spinal cord injuries. This enrollment process is being done to reduce the participation time required for spinal cord injury participants, and thus lower the likelihood of risks that are more prevalent among spinal cord injury participants.

Arm Intervention/treatment
Active Comparator: Healthy Volunteers
This arm consists of healthy volunteers receiving electrical stimulation of the muscles within the forearm via an investigational (not FDA approved) neuromuscular stimulator.
Device: Participants will receive neuromuscular electrical stimulation via an investigational (not FDA approved) neuromuscular stimulator.
The study involves the administration of various electrical pulses being delivered to muscles of the forearm from a neuromuscular stimulator in order to evoke different hand and finger movements. The grip strength and evoked forces at the fingertips will also be measured using sensors.

Primary Outcome Measures :
  1. The primary outcome of the study is to determine the feasibility of achieving refined hand movements through electrical stimulation of the muscles within the forearm, as assessed by visual inspection. [ Time Frame: This outcome measure will be assessed at each study session throughout the 8-week duration of the study. ]
    The primary outcome measure will be achievable wrist and finger movements that will be visually assessed for the type and extent of motion in relation to the stimulation parameters and electrode spatial configurations. The extent of wrist, forearm, and individual finger movements will be categorized as either flexion, extension, adduction, abduction, pronation, or supination and graded as no movement, slight movement, moderate movement, or substantial movement.

  2. The primary outcome of the study is to determine the feasibility of achieving refined hand movements through electrical stimulation of the muscles within the forearm, as assessed by force sensors. [ Time Frame: This outcome measure will be assessed at each study session throughout the 8-week duration of the study. ]
    The primary outcome measure will be achievable wrist and finger movements that will be assessed by the exerted force (measured in Newtons by force sensors on the fingers and palm) in each of the flexion, extension, adduction, abduction, pronation, or supination movements. This will provide the magnitude of the movement in relation to the stimulation parameters and electrode spatial configurations.
