A common rehabilitation goal of superficial heat is to facilitate greater ADL performance by achieving which combination?

• A. Pain reduction and ROM improvement enable greater ADL performance
• B. Increased muscle size
• C. Increased bone density
• D. Decreased skin temperature

Answer: (A)

When superficial heat is used, the main outcome is reducing pain and improving range of motion, which together enable greater performance of activities of daily living. Warming tissues increases local blood flow and tissue elasticity, helping joints move more freely and reducing muscle guarding. With less pain and greater ROM, individuals can perform tasks like dressing, grooming, and cooking more comfortably and effectively.

Heat does not directly increase muscle size or bone density; those changes come from long-term strength training and mechanical loading or bone remodeling, not from superficial heating. Also, superficial heat tends to raise, not decrease, skin temperature, so decreased skin temperature wouldn’t be a goal or expected effect.
