Exercise is beneficial for people with Multiple Sclerosis (pwMS). However, exercise options for those with moderate to high levels of disability are limited. Cycling, delivered with an Active Passive Trainer (APT) is one exercise option often offered within rehabilitation/exercise settings and many pwMS buy APTs for home use. Anecdotally, pwMS report they feel better and their spasticity reduces after APT cycling, however there is a lack of evidence to support this.
