The so-called ultrashort wave therapy is a method of treating diseases by applying ultrashort wave current with a wavelength of 1~10m. Ultrashort wave therapy has the following effects: eliminating inflammation, accelerating tissue regeneration, improving blood circulation in local tissues, relieving spasms, relieving pain, and regulating the functions of nerves, endocrine organs and internal organs. It is currently used in the treatment of inflammatory diseases such as lymphadenitis, pharyngitis, boils, mastitis, bronchitis, osteomyelitis and appendicitis. It also has a therapeutic effect on thrombophlebitis, vasculitis and other diseases. Contraindications to ultrashort wave therapy include the presence of bleeding tendencies, severe heart disease or active tuberculosis. This treatment must be performed by a medical professional after a comprehensive assessment of the condition, and must not be used blindly.
