Iontophoresis, a treatment for inflamed joint and muscle problems, is regaining popularity as an alternative to injections and other treatments. The technique, first developed in the mid 1700’s, involves introduction of various medications (in the form of ions) through the skin by means of electricity. Using a low-volt direct electrical current, an ion, acting as an anti-inflammatory or pain-relieving medicine, penetrates the skin into the painful area.
Iontophoresis offers some advantages. It is cost-effective and portable, although the operator must be a licensed health professional. There is often less risk and discomfort than an injection. Unlike pills, it eliminates the absorption and loss of medication into the digestive tract. Also, less medication will have to be handled by the liver, and there is a much lower chance of overdose.
Although iontophoresis has many advantages, it may not be beneficial for everyone. It should not be used on people who have very sensitive skin or are sensitive to any ion that is proposed for treatment. Occasionally, skin irritation, even small blisters can occur on the area where the treatment is applied. In addition, the treatment often requires a series of applications, rather than just one appointment.
This type of treatment has been used successfully to treat tendinitis, bursitis, and arthritis, even gout. It has also been shown to help reduce calcium deposits in muscle,( a condition called myositis ossificans) that sometimes occurs following injury to a muscle. It works best for inflamed tissues that are not too deep below the skin’s surface, since most anti-inflammatory ions can penetrate only about ½ inch. The procedure is most often performed by licensed physical therapists, following referral from your physician. The therapist and physician determine which ion would be most beneficial for each condition. Some physicians also perform intophoresis treatments. If you suffer from one of the conditions mentioned in this article which have not responded adequately to injections or medication, you may want to ask your doctor about iontophoresis.
