Physical therapy after a stroke is an example of which level of disease prevention?

• A. Primary
• B. Secondary
• C. Tertiary
• D. Quaternary

Answer: (C)

Physical therapy after a stroke focuses on reducing the disability and preventing complications once a disease has occurred. This aim matches tertiary prevention, which is about minimizing damage and restoring function after the illness. By helping regain movement, retraining motor skills, and preventing issues from immobility like contractures or pneumonia, PT reduces long-term impairment and supports independence. Primary prevention would be about stopping the stroke from happening in the first place, while secondary prevention centers on early detection or preventing progression right after onset. Quaternary prevention isn’t the goal here, as the focus is on recovery and reducing disability.
