Iontophoresis and Phonophoresis
Iontophoresis facilitates delivery of medications into the tissues beneath the skin by electronic transport of ionized drugs in solution. Acetic acid iontophoresis is effective in the treatment of heel pain. Iontophoresis of dexamethasone for plantar fasciitis should be considered when more immediate results are needed. Iontophoresis has also been used to successfully treat plantar hyperhidrosis.
Phonophoresis is a technique that combines topical drug therapy with ultrasound to achieve therapeutic drug concentrations in muscle and other tissues beneath the skin. Ultrasound gels can be formulated to contain medications such as anti-inflammatories and/or anesthetics.
