Which modality would be most appropriate for heating deep tissues?

• A. Diathermy
• B. Cryotherapy
• C. Cryostretch
• D. Conduction

Answer: (A)

Deep tissue heating relies on delivering energy that can penetrate beyond the skin and superficial layers to reach muscles and joint structures. Diathermy uses high-frequency electromagnetic energy that heats tissue from within, allowing meaningful warming of deeper tissues with controlled intensity. That makes it the best choice when the goal is to heat deeper structures. Cryotherapy and cryostretch focus on cooling, not heating, so they don’t achieve the desired warming effect. Conduction heats mainly through direct contact with a hot surface, which tends to warm only surface tissues and becomes less effective for deeper layers.
