Ultrasound for use in applying deep heat can be used for treatment of selected medical conditions such as the relief of pain, muscle spasms and joint contractures. These conditions may be associated with adhesive capsulitis, bursitis with slight calcification, myositis and soft tissue injuries. The CPS Ultrasound, while using any of the applicators available for this device, can provide therapeutic deep heating between 40° and 45°C in all of its operating modes.

The provided document is a 510(k) clearance letter from the FDA for several devices manufactured by Chattanooga Group, Inc., specifically the Forte CPS 400 Stim, Forte CPS 200 Stim, Forte CPS Ultrasound, Forte CPS 400 Combo, and Forte CPS 200 Combo. These are physical therapy devices, and the letter confirms that they are substantially equivalent to devices marketed prior to May 28, 1976.
The document does not contain any information regarding acceptance criteria, device performance studies, sample sizes, expert qualifications, or ground truth establishment. The letter is a regulatory approval document, not a scientific study report. It states that the FDA has reviewed the submission and found the devices substantially equivalent based on the indications for use provided.
Therefore, I cannot fulfill your request for information on acceptance criteria and a study proving device performance from the provided text.
§ 890.5300 Ultrasonic diathermy.
(a)
Ultrasonic diathermy for use in applying therapeutic deep heat for selected medical conditions —(1)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.(2)
Classification. Class II (performance standards).(b)
Ultrasonic diathermy for all other uses —(1)Identification. An ultrasonic diathermy for all other uses except for the treatment of malignancies is a device that applies to the body ultrasonic energy at a frequency beyond 20 kilohertz and that is intended for the treatment of medical conditions by means other than the generation of deep heat within body tissues as described in paragraph (a) of this section.(2)
Classification. Class III (premarket approval).(c)
Date PMA or notice of completion of PDP is required. A PMA or notice of completion of a PDP for a device described in paragraph (b) of this section is required to be filed with the Food and Drug Administration on or before July 13, 1999, for any ultrasonic diathermy described in paragraph (b) of this section that was in commercial distribution before May 28, 1976, or that has, on or before July 13, 1999, been found to be substantially equivalent to an ultrasonic diathermy described in paragraph (b) of this section that was in commercial distribution before May 28, 1976. Any other ultrasonic diathermy described in paragraph (b) of this section shall have an approved PMA or declared completed PDP in effect before being placed in commercial distribution.
