Which of the following best describes Physical Therapy?

Physical therapy is centered around rehabilitation and enhancing physical function through various techniques and interventions. This includes exercises, manual therapy, and modalities such as massage, which are used to promote healing, improve mobility, and reduce pain. The focus on rehabilitation reflects a core aspect of physical therapy, which aims to restore individuals to their optimal physical performance after injuries or surgeries.

The other choices do not encapsulate the essence of physical therapy. Medications (first option) are not a primary method used in physical therapy; rather, they are often part of a broader medical management plan. Sound therapy (second option) is associated more closely with therapeutic practices in music therapy or holistic approaches rather than the scientific, rehabilitative approach of physical therapy. The surgical correction mentioned in the last option, while related to physical health, is a distinct medical intervention rather than a rehabilitative treatment approach.
