ASPIRE trial: study protocol for a double-blind randomised controlled trial of aspirin for overheating during exercise in multiple sclerosis.
Summary
This study investigates the use of aspirin as an exercise pre-treatment to reduce overheating and exhaustion, which may potentially allow many more people with multiple sclerosis to participate in and benefit from exercise. The design is double-blind, within-subject, with three arms: participants will receive one of three treatments at three separate study visits: aspirin, acetaminophen, and placebo, followed by completion of a maximal exercise test.
