Prevention or retardation of disuse atrophy. Increasing local blood circulation. Muscle re-education. Immediate post-surgical simulation of calf muscles to prevent venous thrombosis. Maintaining or increasing range of motion. ## Device Story CLASSIC NMS™ is a powered muscle stimulator used for therapeutic muscle stimulation. Device delivers electrical output to muscles to achieve clinical goals including spasm relaxation, atrophy prevention, circulation improvement, muscle re-education, and post-surgical thrombosis prevention. Operated by clinicians or patients in clinical or home settings. Output characteristics are electrically equivalent to predicate device. Device utilizes jacks and cables compliant with FDA performance standards for electrode lead wires and patient cables. Benefits include improved muscle function and prevention of post-surgical complications. ## Clinical Evidence No clinical data. Substantial equivalence determined via bench testing of electrical output characteristics. ## Technological Characteristics Powered muscle stimulator (21 CFR 890.5850). Electrical stimulation via electrodes. Features jacks and cables compliant with FDA performance standards for electrode lead wires and patient cables. Standalone device. ## Regulatory Identification A powered muscle stimulator is an electrically powered device intended for medical purposes that repeatedly contracts muscles by passing electrical currents through electrodes contacting the affected body area. ## Predicate Devices - Ortho Dx ([K971542](/device/K971542.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

McLean, VA 22102 June 7, 2002 Date of preparation: CLASSIC NMS™ Proprietary Name: Neuromuscular Stimulator Common Name: Powered Muscular Stimulator Classification Name: 21 CFR 890.5850. Device Classification: Class II Ortho Dx (K971542) Predicate Device: A portable NMS device for pain control. Description of Device: Intended Use: Relaxation of muscle spasms ﺘﻌ Prevention or retardation or disuse atrophy -Increasing local blood circulation -Muscle re-education -Immediate post-surgical simulation of calf muscles to prevent venous thrombosis Maintaining or increasing range of motion -The CLASSIC NMS™ has technological characteristics that are Technological Comparison: substantially equivalent to those of the predicate device, as determined by bench testing. It differs technologically only by the use of jacks and cables which comply with FDA's Fnal Rule "Medical Devices; Establishment of a Performance Standard for Electrode Lead Wires and Patient Cables." The labeling of the CLASSIC NMS™ is substantially equivalent to that Labeling Comparison: of the predicate device. Bench testing demonstrated that the output characteristics or CLASSIC Nonclinical Testing: NMS™ are substantially equivalent to that of the predicate device. Clinical Testing: Not applicable. The CLASSIC NMS™ is substantially equivalent in electrical output to Conclusions from Testing: the predicate device and any differences between the devices do not pose new questions of safety and effectiveness. # 510(k) Summary {1}------------------------------------------------ Image /page/1/Picture/1 description: The image shows the seal of the Department of Health & Human Services - USA.

Hunt President Care Rehab® 1124 Dominion Court McLean, Virginia 22102 Re: K021905 Trade/Device Name: Classic NMSTM Regulation Number: 21 CFR 890.5850 Regulation Name: Powered Muscle Stimulator Regulatory Class: Class II Product Code: IPF Dated: June 7, 2002 Received: June 10, 2002 Dear Mr. Hunt: We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
