The Diathermy or Radiofrequency is a non-invasive therapy that uses high-frequency electromagnetic waves to generate therapeutic heat deep into the tissues of the body. This heat is produced by the natural resistance of the tissue to the passage of these waves, which induces an increase in blood circulation, muscle relaxation and pain reduction.

It is used to treat a variety of conditions, musculoskeletal, joint and soft-tissue, promoting healing and symptomatic relief through the internal heating.
