Who this trial is looking for
This trial is looking for adults with multiple sclerosis to explore a breathing treatment that involves short periods of low oxygen. Participants will have their brain activity and ankle strength measured before and after the treatment.
Are You a Good Fit for This Trial?
Must be takingDalfampridine
You may be able to join if
I have been diagnosed with relapsing form of multiple sclerosis.
My disability score is between 3 and 6.5.
I have a motor function score between 2 and 4.
I have not had a relapse in the last year.
I am between 18 and 75 years old.
I can safely undergo an MRI scan.
I take dalfampridine at the same dose for at least 2 months.
You may not be able to join if
I have active or recent lesions on my MRI scan.
I have uncontrolled high blood pressure.
I have a history of epilepsy.

This study aims to understand the mechanisms of a novel intervention involving breathing short durations of low levels of oxygen for persons with multiple sclerosis (MS). This intervention with low levels of oxygen is called Acute Intermittent Hypoxia (AIH), the levels of oxygen experienced are similar to breathing the air on a tall mountain, for less than 1 minute at a time. Previous studies have…
This study aims to understand the mechanisms of a novel intervention involving breathing short durations of low levels of oxygen for persons with multiple sclerosis (MS). This intervention with low levels of oxygen is called Acute Intermittent Hypoxia (AIH), the levels of oxygen experienced are similar to breathing the air on a tall mountain, for less than 1 minute at a time. Previous studies have shown that AIH is a safe and effective way to increase strength in persons with MS. Here the investigators aim to look at brain activation and ankle strength before and after AIH to gain a better understanding of how the AIH may improve strength in those persons with MS.
