First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a type of spinal cord stimulation that uses low-level electrical pulses (below the sensation threshold) against the best available medical treatments for people with ongoing back and leg pain after back surgery. About 114 participants will be randomly assigned to one of the two approaches. The goal is to see if this stimulation method leads to better overall well-being, pain relief, and function after six months.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: subthreshold spinal cord stimulation
What this could lead to: If successful, this could provide a non-drug option for managing chronic back and leg pain after failed back surgery, potentially reducing pain and improving quality of life.
What could go wrong: This is a relatively small, early-stage trial with no phase designation. The treatment may not prove more effective than standard medical care, and spinal cord stimulation carries risks like infection or device malfunction.
