Spinal injury study maps brain pathways to restore hand movement
NCT ID NCT02451683
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed study looked at how the brain controls muscles after a spinal cord injury. Researchers tested 120 people with chronic neck-level injuries to measure nerve signals and motor function. The goal was to better understand how to improve hand and arm movement for daily tasks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this research could point toward new rehabilitation strategies to improve hand and arm function after spinal cord injury.
- What could go wrong
- This is an observational and early-stage study, not a treatment trial. Results may not directly lead to a therapy or benefit all patients.

Inclusion Criteria: * Inclusion criteria for individuals with SCI: 1. Male and females between 18-85 years, 2. Chronic SCI (≥ 6 months post injury), 3. Cervical injury at C8 or above, 4. Intact or impaired but not absent innervations in dermatomes C6, C7, and C8 using the American Spinal Injury Association sensory scores, and 5. Ability to reach and grasp a small object located at least 8 cm forward, above, and laterally without leaning forward with the trunk Inclusion criteria for healthy controls: 1. Male and females between 18-85 years, 2. Right handed, 3. Ability to reach and grasp a small object located at least 8 cm forward, above, and laterally without leaning forward with the trunk Exclusion Criteria: * Exclusion criteria for individuals with SCI and Healthy Controls: 1. Uncontrolled medical problems including pulmonary, cardiovascular or orthopedic disease 2. Any debilitating disease prior to the SCI that caused exercise intolerance 3.
