Scientists test spinal zaps on healthy volunteers to fine-tune settings
NCT ID NCT06116838
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests how changing the type, speed, and location of mild electrical stimulation on the spine affects leg muscle twitches and comfort in 50 healthy adults aged 18-75. Participants receive stimulation while resting or walking on a treadmill and report what feels tolerable. The goal is to gather basic knowledge to guide future therapies, not to treat any disease.
