Home breathing exercises to help preserve lung function in ALS

This study is testing a medical device called the LIC Trainer that helps people with ALS perform breathing exercises at home. The device uses a one-way valve to gently inflate the lungs without requiring you to consciously hold your breath — something that becomes difficult as ALS progresses. The goal is to see whether using this device twice daily can help maintain your lung strength, reduce breathing problems, and possibly extend survival.

ALS weakens the muscles you use to breathe, which is one of the most serious complications of the disease. While a traditional breathing therapy exists, it doesn't work well for people with advanced ALS, especially those who have lost the ability to control their throat muscles or have had a tracheostomy. This trial exists to test whether the new device can overcome these limitations and help more people with ALS benefit from breathing therapy.
