Spinal stimulation without surgery shows promise for spasticity relief
NCT ID NCT03815721
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a device that sends electrical stimulation through the skin to the spinal cord, aiming to reduce muscle spasticity and improve movement in people with incomplete spinal cord injury. Twelve participants received repeated sessions of the stimulation. The goal was to see if the benefits could last beyond the treatment period. The trial was terminated early, so the full results are not available.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcutaneous spinal cord stimulation device
- What this could lead to
- If it works, this could offer a non-invasive, home-based way to reduce muscle spasticity and improve movement for people with spinal cord injury.
- What could go wrong
- The trial was terminated early with only 12 participants, so results are limited. The effects may not last or work for everyone.

Inclusion Criteria: * motor and sensory incomplete spinal cord injury classified as grade C or D on the American Spinal Injury Association Impairment Scale * neurological level of spinal cord injury: third cervical to tenth thoracic segment * chronic condition (≥ 12 months post-spinal cord injury) * preserved segmental and cutaneo-muscular reflexes in the lower limbs * able to be verticalized for 6 minutes (with walking aids) * preserved joint mobility, no musculoskeletal diseases * spasticity (with/without antispasticity medication) * stable antispasmodic medication one month prior to as well as during study participation Exclusion Criteria: * neuromuscular diseases, e.g., amyotrophic lateral sclerosis (ALS), Parkinson's disease, Guillain-Barré syndrome, muscular dystrophy * dermatological issues at the stimulation site * acute urinary tract infection at study entry * active implants (e.g., cardiac pacemaker, drug pump) * passive implants between the ninth thoracic level and the first lumbal level (e.g. metal screws/plates for surgical stabilization of spinal fractures) * malignant diseases * heart insufficiency * potential pregnancy (pregnancy test to be conducted as part of the first evaluation)
