Which is a contraindication for ultrasound therapy?

• A. Deep vein thrombosis
• B. Dermal ulcers
• C. Plantar warts
• D. Muscle spasm

Answer: (A)

Ultrasound therapy uses energy to heat and stimulate tissues, which can aid healing but also carries risks if there’s a clot present. A deep vein thrombosis means there’s a thrombus in a major vein, and applying ultrasound could potentially loosen or move that clot, increasing the chance of a pulmonary embolism. Because of this safety risk, a DVT is a contraindication to ultrasound therapy. Dermal ulcers can sometimes benefit from ultrasound as part of wound care, and muscle spasm can be helped by the heating effect of ultrasound. Plantar warts are skin lesions and do not inherently forbid ultrasound unless other contraindications exist. In short, the key safety signal is avoiding ultrasound over a suspected or known deep vein thrombosis.
