Topical medications may be administered by a physical therapist through which method?

Topical medications can be effectively administered by a physical therapist using iontophoresis, which is a technique that utilizes a low electrical current to drive ionized medications through the skin and into deeper tissues. This method enhances the penetration of drugs, facilitating localized treatment for conditions like inflammation, pain, or muscle spasms. Iontophoresis allows for targeted delivery of medications directly to the site of discomfort, making it a commonly employed approach in physical therapy.

In contrast, the other methods listed are not appropriate for the administration of topical medications in a physical therapy setting. Acupuncture techniques primarily involve the insertion of needles into specific points of the body to relieve pain or treat various conditions, but do not involve the application of topical medications. Barometric Pressure therapy, often used to promote healing by altering air pressure, does not involve the delivery of medications through the skin. Finally, invasive surgical methods are unrelated to the therapeutic application of medications in non-invasive treatment modalities typically used by physical therapists.
