Swim therapy for a teenager with cerebral palsy is categorized as tertiary prevention because it focuses on managing and improving the quality of life for individuals with chronic conditions. Tertiary prevention aims to reduce the impact of an ongoing illness or injury that has lasting effects. In this case, swim therapy is used to help improve physical function, mobility, and overall well-being in an individual with cerebral palsy, effectively minimizing secondary complications and enhancing quality of life.

While primary prevention refers to efforts to prevent the occurrence of a disease or condition before it starts, and secondary prevention involves early detection and management to limit the effects of a disease, swim therapy is specifically focused on aiding someone who already has a condition. Health education, while important in promoting awareness and knowledge, does not encapsulate the therapeutic intent and physical rehabilitation aspects of swim therapy. Thus, the correct classification of swim therapy in this context is tertiary prevention.
