What risk is associated with not moving the sound head during treatment?

• A. Potential tissue damage
• B. Improved comfort
• C. Faster recovery
• D. Reduced heating

Answer: (A)

Not moving the sound head during therapeutic ultrasound increases the risk of localized overheating and tissue damage. When the transducer stays in one spot, the energy concentrates in a small area, raising the tissue temperature and potentially causing skin burns or deeper tissue injury. Standing waves can also form, creating unpredictable peaks in energy at certain depths. Moving the head distributes the energy more evenly, promoting uniform heating and reducing the chance of a dangerous temperature rise. Always maintain good gel coupling, use appropriate settings, and monitor the patient. The other options don’t reflect the real hazard: stationary use does not improve comfort or speed recovery, and it does not reduce heating; it actually raises the risk of heat-related injury.
