Respiratory Training in Friedreich's Ataxia

Not Applicable

Recruiting

• Conditions: Friedreich Ataxia

• Registration Number: NCT06539598
• Lead Sponsor: University of Florida

Brief Summary

This is a prospective interventional study of patients with Friedreich's Ataxia that receive respiratory strength training for a period of 12 weeks with two research visits at the beginning and at the end of the study period. Visits include swallowing evaluation with fiberoptic endoscopic evaluation of swallowing, pulmonary function testing, surface electromyography and patient surveys.
