Summary

This study aimed to see if adding a mild electrical current to the brain (transcranial stimulation) during shoulder strengthening exercises helps people with subacromial pain syndrome more than exercise alone. Participants would have done 8 weeks of shoulder exercises while wearing a helmet that delivered either real or fake stimulation. However, the trial was withdrawn before any participants were enrolled, so no data was collected.

What this could mean

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

Active substance: transcranial electrical stimulation (a-TES)
What this could lead to: If it worked, this could point toward a way to boost the effects of physical therapy for shoulder pain using mild brain stimulation.
What could go wrong: The trial was withdrawn before enrolling anyone, so no results exist. Even if run, it was a small early study and the added benefit of brain stimulation may be minimal or none.
