Phonophoresis

Phonophoresis is the use of ultrasound to enhance the delivery of topically applied drugs. Phonophoresis has been used in an effort to enhance the absorption of topically applied analgesics and anti-inflammatory agents through the therapeutic application of ultrasound.

Phonophoresis has been shown to be ineffective for some treatments, where it did not increase the efficacy of absorption of drugs, or did not improve the outcome more than the use of ultrasound alone.
