Gentle neck zap may help ALS patients swallow again
NCT ID NCT07606235
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tests a non-invasive device that stimulates a nerve in the neck to see if it can increase how often people with ALS swallow and their urge to swallow. Up to 5 participants will receive supervised treatment sessions and be monitored with swallowing tests. The goal is to check if the approach is safe and feasible for a larger future trial.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- transcutaneous electrical nerve stimulation of the superior laryngeal nerve (TENS-SLN)
- What this could lead to
- If it works, this could point toward a non-invasive way to help people with ALS swallow more easily and safely.
- What could go wrong
- This is a very early pilot study with only 5 participants, designed to test feasibility, not effectiveness. It may not show meaningful improvement or lead to a proven treatment.

Inclusion Criteria: * Confirmed diagnosis of ALS (El-Escorial Criteria) * ALS FRS Bulbar Subscore of ≤ 10 and ≥ 3. * Functional Oral Intake scale score ≥ 2 Exclusion Criteria: * A diagnosis of significant cognitive impairment or frontotemporal dementia per the treating neurologist or neuropsychologist, * Current nasogastric tube placement * Current head and neck carcinoma * Pacemaker or implanted defibrillator or history of diagnosed arrhythmia, bradycardia, or repeated attacks of hypotension, * Implanted vagal nerve stimulator * Current pregnancy * History of epilepsy * Infected, broken or inflamed skin on the neck, or impaired sensation at the site of sEMG or TENS placement * Living greater than 50 miles from the NSU clinic round trip * Any clinical reason that this stimulation may not be a suitable treatment according to the principal investigator.
