Which area is listed as a contraindication for ultrasound therapy?

• A. Eyes
• B. Elbow
• C. Knee
• D. Back

Answer: (A)

Ultrasound therapy delivers energy that can raise tissue temperature and produce mechanical effects. Some areas are especially sensitive to this energy, so they’re avoided to prevent injury. The eyes are highly vulnerable to heating and energy-related damage to delicate ocular structures, which can lead to problems like cataracts or retinal injury. For that reason, the eyes are a contraindicated area for ultrasound treatment. Elbow, knee, and back are common treatment sites when there are no contraindications, because they can safely respond to the thermal and non-thermal effects of ultrasound. The decision to use ultrasound there depends on the absence of conditions that would preclude therapy (such as open wounds, acute injuries, or infections) rather than an innate contraindication of those areas.
