Could a zapping device help MS patients swallow safely?
NCT ID NCT05063708
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether adding a mild electrical stimulation device to standard swallowing therapy helps people with multiple sclerosis who have trouble swallowing. 136 participants were randomly assigned to receive either real electrical stimulation or a sham device alongside their therapy. The goal was to see if the electrical stimulation improves swallowing function and reduces the risk of pneumonia.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- neuromuscular electrical stimulation (NMES) device
- What this could lead to
- If it works, this could offer a better way to improve swallowing safety and reduce pneumonia risk in people with multiple sclerosis.
- What could go wrong
- This is a completed trial, but results are not yet widely confirmed. Previous studies on NMES for swallowing have shown mixed results, so the added benefit may be small or absent.
