An intensity of 1.5-2.0 W/cm2 is typically what?

• A. Ideal for deep heating
• B. Usually too hot
• C. Insufficient energy
• D. No heating at all

Answer: (B)

The main idea here is how ultrasound intensity relates to heating depth. An intensity of 1.5–2.0 W/cm2, when applied continuously, delivers enough energy to raise the temperature of deeper tissues. That makes it ideal for deep heating, such as warming muscle and connective tissue to improve extensibility and reduce stiffness. When used with proper coupling, treatment time, and patient feedback, this range provides meaningful thermal effects without being uncomfortably hot. If the energy were much higher, or used for too long without monitoring, overheating could occur; if it were much lower or used with pulsing, the heating would be insufficient. So this level is a standard deep-heating setting in therapeutic ultrasound.
