Answers
Answer:
3. Inflammation
Explanation:
In rehabilitation medicine, including physical therapy, iontophoresis is used to reduce inflammation that might be seen in musculoskeletal conditions such as lateral epicondylitis, medial epicondylitis, plantar fasciitis, tendo-nitis/bursitis, rheumatoid arthritis, and enthesopathic conditions of various origins. The most popular and well researched iontophoresis application is the use of dexamethasone, a corticosteroid in a sodium phosphate solution. In this form, the drug is composed of negatively charged ions of dexamethasone phosphate and, when loaded into a negatively charged reservoir or electrode pad, the electrical force of the like charges pushes the medication molecules into the desired area. There are two commonly used ways of applying iontophoresis; the first is the traditional method of using a current generator with lead wires connected to an active pad and a dispersive pad (see Figure 1). The medication is loaded in the active pad usually by syringe. The dispersive pad is the polar opposite pad and located away from the treatment site. The treatment is administered clinically for 15-20 minutes per session. In a physical therapy setting, iontophoresis is typically one of several treatment interventions applied, so the addition of another 15-20 minutes to a pre-existing 60 minute program is a time burden for some patients. One ionto-phoresis manufacturer has responded to this situation by introducing a more mobile solution to iontophoresis treatment—sold under the brand name of IontoPatch®—that may be worn by the patient for a 24-hour period. In this way, the clinical time component of this treatment is eliminated altogether and the patient gets a more sustained 24 hour effect. These mobile IontoPatches contain a small flat battery that provides a tiny electrical “push” of the target medication
