Spinal zaps may help people with standing tremor stay upright longer
NCT ID NCT02978924
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This small study tested whether a mild electrical current applied to the spinal cord (tsDCS) could help people with primary orthostatic tremor, a rare condition that causes leg shaking when standing. 18 participants received either real or sham stimulation. The main goal was to see if they could stand longer without support. Researchers also measured tremor and brain activity.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- trans-spinal direct current stimulation (tsDCS) device
- What this could lead to
- If it works, this could point toward a non-drug way to help people with primary orthostatic tremor stand more steadily.
- What could go wrong
- This is a very small, early study with only 18 people. The effect may be small or not last, and it may not work for everyone.
