What technique does phonophoresis utilize for medication delivery?

• A. Electromagnetic waves
• B. Cold therapy
• C. Ultrasound waves
• D. Infrared light

Answer: (C)

Phonophoresis is a technique that utilizes ultrasound waves for the delivery of medications through the skin. This method enhances the absorption of topical drugs by using mechanical vibrations caused by high-frequency ultrasound. The ultrasound waves create microscopic bubbles in the tissue fluids, which help drive the medication deeper into the tissues, increasing its effectiveness and providing targeted therapy. The use of ultrasound in phonophoresis is particularly effective because it can increase the permeability of the skin, allowing for improved transdermal absorption of certain medications, such as anti-inflammatory agents or analgesics. This is why ultrasound waves are the correct choice for this method. Other options, such as electromagnetic waves or infrared light, are associated with different therapeutic modalities, such as diathermy or heat therapy, but do not involve the mechanism of phonophoresis. Cold therapy also does not play a role in enhancing drug delivery through the skin in the way that ultrasound does.
