One-person trial tests breathing workouts for rare nerve disease
NCT ID NCT06539598
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether 12 weeks of respiratory strength training could improve breathing and swallowing in a person with Friedreich's ataxia. The participant did breathing exercises against resistance and had tests before and after the training. Because only one person took part, the results are very limited and cannot be generalized.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Respiratory strength training (breathing exercises against resistance)
- What this could lead to
- If it works, this could point toward a simple exercise program to help people with Friedreich's ataxia breathe and swallow better.
- What could go wrong
- This was a very small study with only one participant, so results may not apply to others. It also only looked at short-term effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * confirmed genetic testing of Friedreich's Ataxia * have an overall DIGEST score of 1 or higher based on FEES screening * are able to perform pulmonary function testing Exclusion Criteria: * have been on antibiotics within 15 days prior to baseline screening. * have been prescribed systemic corticosteroids or neuromuscular blocking agents within 15 days of the baseline screening * have an allergy or contraindication to topical lidocaine or oxymetazoline * have any other concurrent medical condition which, in the opinion of the investigators, would make the subject inappropriate to participate in testing or respiratory exercise
