Iontophoresis and phonophoresis

Iontophoresis and phonophoresis

It is the use of direct electrical current to induce topically applied medications to migrate into soft tissues and nerves up to 3 to 5 mm deep. Common topical medications applied include lidocaine gel, corticosteroid (usually dexamethasone) gel, and analgesics. This therapy has been used in tendonitis (especially Achilles tendonitis), bursitis, and neuritis. Phonophoresis is similar to iontophoresis except it uses ultrasound to “drive” medication more deeply.
