Brain training may strengthen movement after spinal cord injury
NCT ID NCT04286191
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a brain-spinal cord-muscle training program can strengthen connections that control movement in people with spinal cord injury. Twenty-one participants completed four months of training using brain stimulation and muscle monitoring. The goal was to see if this training could improve walking and reduce muscle spasticity.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Operant conditioning training with transcranial magnetic stimulation (TMS)
- What this could lead to
- If successful, this training approach could point toward a non-invasive way to improve walking and movement control after spinal cord injury.
- What could go wrong
- This is a small, early-stage study (21 participants) focused on measuring changes in the nervous system, not on proving a treatment works. Results may not apply to everyone with spinal cord injury.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Neurologically stable (\>1 year post SCI) * Medical clearance to participate * Ability to ambulate at least 10 m with or without an assistive device (except for parallel bars) * Signs of weak ankle dorsiflexion at least unilaterally * Expectation that current medication will be maintained without change for at least 3 months; stable use of anti-spasticity medication is accepted Exclusion Criteria: * motoneuron injury * known cardiac condition (e.g., history of myocardial infarction, congestive heart failure, pacemaker use) * medically unstable condition * cognitive impairment * history of epileptic seizures * metal implants in the cranium * implanted biomedical device in or above the ches (e.g., a cardiac pacemaker, cochlear implant) * no measurable MEP elicited * unable to produce any voluntary TA EMG activity * extensive use of functional electrical stimulation to the leg on a daily basis * pregnancy (due to changes in weight and posture and potential medical instability)
