Used in clinical settings by healthcare professionals to treat pain, muscle spasms, and joint contractures. Devices operate by delivering acoustic energy to tissues; heat generation facilitates therapeutic effects. Clinicians apply treatment based on patient condition; output affects clinical decision-making by providing non-invasive thermal therapy. Benefits include symptom relief and improved joint mobility. ## Clinical Evidence No clinical data provided; substantial equivalence based on technological characteristics and intended use. ## Technological Characteristics Therapeutic ultrasound device; generates deep heat via ultrasonic energy. Class II device (Product Code: IMI). ## Regulatory Identification An ultrasonic diathermy for use in applying therapeutic deep heat for selected medical conditions is a device that applies to specific areas of the body ultrasonic energy at a frequency beyond 20 kilohertz and that is intended to generate deep heat within body tissues for the treatment of selected medical conditions such as relief of pain, muscle spasms, and joint contractures, but not for the treatment of malignancies. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
