Which condition is an indication for thermal ultrasound?

• A. Soft tissue shortening
• B. Acute infection
• C. Fracture
• D. Edema

Answer: (B)

Thermal ultrasound is used to heat tissues to increase their elasticity and extensibility. When soft tissue shortening is present, warming the area helps the collagen fibers become more pliable, reducing stiffness and allowing a greater range of motion. That’s why soft tissue shortening is the appropriate indication for thermal ultrasound. Acute infection is not an indication; heat can worsen inflammation and infection, so heating is avoided in the acute phase. Fracture is also a contraindication because heating near a fracture can interfere with healing and stability. Edema is not an indication for thermal heating; reducing swelling is generally addressed with cold or nonthermal approaches, while ultrasound might be used nonthermally in some cases if appropriate.
