Spinal stimulation + cycling: new hope for leg function after injury?
NCT ID NCT07445685
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a gentle electrical current applied to the spinal cord (transcutaneous spinal cord stimulation) during assisted cycling can improve leg movement, reduce muscle spasms, and help bladder/bowel control in adults with incomplete spinal cord injury. Forty participants who have been injured for less than a year will receive either real stimulation or a sham (fake) stimulation during cycling sessions. Researchers will measure muscle strength, walking ability, and safety.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age at least 18. * Diagnosis of spinal cord injury at levels C2-T11, classified as ASIA Impairment Scale grades B, C, or D. * Less than 1 year since the injury. * Ability to follow instructions and tolerate the intervention. .-Spasticity grade less than 3 on the Modified Ashworth Scale. * Signed informed consent. Exclusion Criteria: * Comorbidities that limit active participation (severe heart disease, serious active infections, pressure ulcers in the area). * Use of devices incompatible with electrical stimulation. * Metallic implant in the T11-T12 area. * History of epilepsy. * Fixed joint contractures limiting range of motion. * Significantly reduced bone density (osteoporosis). * Unhealed fractures. * Pregnancy. * Active tumor process.
