Which of the following is a deep thermotherapy modality?

• A. Ultrasound
• B. Infrared lamp
• C. Paraffin
• D. Fluidotherapy

Answer: (A)

Deep heating aims to raise tissue temperature in deeper structures to help with pain, stiffness, and tissue extensibility. Ultrasound does this by delivering high-frequency sound waves that convert to heat within tissues, with depth adjustable by frequency—1 MHz can reach several centimeters, making it a true deep thermotherapy modality. The infrared lamp primarily heats surface tissues through radiant energy, with limited depth. Paraffin provides superficial heat to the skin and joints, while fluidotherapy uses heated air and particulates to warm mainly superficial tissues and permit movement. So, ultrasound uniquely provides deep heating, fitting the goal of deep thermotherapy.
