Sleeve that reads muscle signals may restore hand grasp in paralysis
NCT ID NCT06087445
First seen Jun 27, 2026 ยท Last updated Jun 27, 2026
Summary
This pilot study tested a sleeve worn on the forearm that uses muscle signals to stimulate hand muscles, helping people with tetraplegia from spinal cord injury grasp and manipulate objects. Twelve adults with chronic cervical SCI completed a 12-week training program using the device. Researchers measured safety, feasibility, and early improvements in hand function.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- NeuroLife EMG-FES Sleeve System (a non-invasive device with surface electrodes that records muscle activity and stimulates muscles to help hand function)
- What this could lead to
- If it works, this could provide a non-implant way for people with tetraplegia to regain some hand control, improving daily tasks like gripping and pinching.
- What could go wrong
- This was a small pilot study with only 12 participants, so results may not apply to everyone. The device is still experimental, and long-term benefits or risks are not yet known.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. age 22 years or older 2. sustained a chronic (\>12 months) cervical SCI (AIS A, B, C, or D) and is currently medically stable 3. unable to grasp and manipulate objects to allow independent performance of activities of daily living (e.g., Tetraplegia) 4. retain voluntary ability to enact unilateral shoulder and elbow movements either independently or with a mobile arm support 5. Willing and able to attend study sessions in Columbus, Ohio for 12 weeks, 3x/week and all assessment sessions (4 weeks prior to and 4 weeks following 12-week intervention protocol) 6. able to provide informed consent. Exclusion Criteria: 1. medical contraindications to FES (e.g., pacemaker or other implanted devices, uncontrolled seizure disorder, cancer or open wounds on hands) 2. severe, uncontrolled autonomic dysreflexia 3. comorbid medical condition that, in the opinion of the PI, that may impact participant safety or study results 4. severe upper extremity spasticity or contractures that prevent FES-evoked wrist and finger movements 5. ventilator dependent 6. pregnant or plan to become pregnant (females only) 7. actively participating in upper extremity rehabilitation.
