Which scenario is a contraindication to exercise in multiple sclerosis?

• A. Stable remission for years.
• B. Acute relapse with severe symptoms or infection.
• C. No fatigue.
• D. Regular gentle activity.

Answer: (B)

During an acute relapse with severe symptoms or an active infection, exercise is contraindicated in multiple sclerosis because this is a time of heightened neurological instability and systemic stress. Relapses reflect new inflammatory damage, and increasing physical demand can worsen symptoms, prolong recovery, and raise the risk of complications. An infection adds fever and immune activation, and overheating can transiently worsen MS symptoms (Uhthoff’s phenomenon), making exercise unsafe and potentially delaying healing. The safest approach is rest and medical treatment during the relapse or infection, with careful, gradual reintroduction to activity once recovered and cleared by a clinician. By contrast, stable remission, absence of fatigue, and regular gentle activity are compatible with, and typically beneficial for, MS management.
