Percutaneous Needle Electrolysis on Metatarsalgia

Study Overview
=================
Brief Summary
-----------------
Percutaneous electrolysis is a minimally invasive method that involves the application of a galvanic current through an acupuncture needle. The needle is placed directly into the soft tissue structures, essential with ultrasound guidance. This technique involves the combination of mechanical stimulation produced by the needle and electrical/biochemical stimulation provided by the electrical current. Endogenous pain modulation shows clinical relevance of this technique and plays an important role in the experience of pain. Plantar plate injury is a pathology that frequently occurs in the forefoot, especially in middle-aged women, causing metatarsalgia that is sometimes very intense. In most cases it is secondary to a mechanical imbalance of the forefoot, related to an insufficiency of the first radius. For this reason, the researchers hypothesize that the application of ultrasound-guided percutaneous electrolysis on the plantar plate, combined with the conservative treatment consisting of the development of a personalized plantar orthosis, can cause positive effects in the patient's clinic as well as improve their quality of life.
