Zapping the spine: a Non-Invasive device aims to loosen stiff muscles and improve walking in cerebral palsy
NCT ID NCT07826494
First seen Sep 17, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
Researchers at the University of Washington are testing whether non-invasive spinal stimulation can temporarily reduce muscle stiffness and improve walking in people with cerebral palsy. The study includes 20 participants aged 4 to 65 who can walk for at least 10 minutes. Participants walk on a treadmill both with and without the stimulation, and researchers measure changes in muscle stiffness, step length, and overall gait quality.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- non-invasive transcutaneous spinal stimulation using a device called SpineX or xStep
- What this could lead to
- If it works, this could offer a drug-free way to ease muscle stiffness and improve walking for people with cerebral palsy.
- What could go wrong
- This is a small, early study of 20 people looking only at short-term effects during a single walking session. Any improvements may not last, and the approach may not help everyone with cerebral palsy.

Inclusion Criteria: Individuals who: * have a diagnosis of spastic cerebral palsy or high likelihood of CP diagnosis * are 4-65 years of age * have spasticity in lower-extremity muscles * are at a functional Gross Motor Function Classification System (GMFCS) Level I-III * can walk for at least 10 minutes with/without support * can understand and follow simple directions * have a stable medical condition, as reported by the caregiver/parent Exclusion Criteria: Individuals who: * who have had lower-extremity surgery or injury in the prior 12 months * have had botulinum toxin injections in the prior 3 months * have had selective dorsal rhizotomy (SDR) in the past * have uncontrolled seizures * have significant cardiovascular or musculoskeletal disease that would prevent full participation * are dependent on ventilation support * have implanted stimulator (e.g. epidural stimulator, vagus nerve stimulator, pacemaker, cochlear implant, etc) or drug delivery device (e.g. baclofen pump) * have established osteoporosis and taking medication for osteoporosis treatment. * have rheumatic diseases (rheumatoid arthritis, systemic lupus erythematosus, etc.) * have active cancer * have received stem cell injections into the spinal cord
