The task of iontophoresis is to introduce active (therapeutic) substances into the deep layers of the skin. This is done using direct current. Iontophoresis is used for neuralgia, post-traumatic pain, as well as bone fusion disorders.
The physiotherapist applies an appropriately selected medication to the treated area, and then places an active electrode on it, and a passive electrode on the opposite side. The current flowing between the electrodes speeds up the process of absorption of the drug. During the procedure, the patient may feel a tingling or pricking sensation from the needles on the skin.
