Device Story
E-Fit EF-1280 is a powered muscle stimulator using EMS technology; designed for healthy individuals as an adjunct to sports and muscle training. Device delivers electrical impulses to trigger action potentials on motor nerves; impulses transmitted to motor endplates to generate mechanical muscle fiber responses. Parameters (pulse frequency, contraction/rest duration) are adjustable to impose different types of muscle work. Operated by certified professionals in a clinical or training setting; user wears hygroscopic cotton underwear soaked in tap water to serve as conductive media for fixed electrodes. Output is controlled via rotary encoder and push buttons; system includes safety monitoring (short-circuit, watchdog, battery, current). Benefits include improved muscle performance through targeted training. Not for rehabilitation or medical treatment.
Clinical Evidence
Bench testing only. No clinical data provided. Device performance verified through compliance with IEC 60601-1, IEC 60601-1-2, IEC 60601-1-11, and IEC 60601-2-10 standards, alongside software verification per FDA guidance.
Technological Characteristics
Powered muscle stimulator; stainless steel enclosure. Symmetric biphasic waveform; 5-120Hz frequency; 100-500usec pulse width. 12V lead-acid battery power. Conductive interface via water-soaked cotton underwear. Safety features: short-circuit, watchdog, no-load/on-load, battery, and output current monitoring. Standards: EN ISO 14971:2012, EN ISO 13485:2003, IEC 60601-1:2005, IEC 60601-1-2:2007, IEC 60601-1-11:2010, IEC 60601-2-10:2012.
Indications for Use
Indicated for healthy muscles and clients to improve or facilitate muscle performance. Contraindicated for use on injured or ailing muscles, or in conjunction with therapy or treatment of medical diseases or conditions.
Regulatory Classification
Identification

Dear Ms. Alexander:
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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act

## Indications for Use
510/k) Number (if known) K133225
Device Name E-Fit EF-1280
#### Indications for Use (Describe)
E-Fit EP-1280 is a machine with electronic muscle stimulation based on EMS technology. Regarding is use, the device is specifically designed as an addition to other sports and for training muscles. It must be used for only healthy museles and clients, not for rehabilitation purposes.
The E-Fit EF-1280 intended to stimulate healthy muscles in order to improve or facilitate muscle performance. The E-Fit EF-1280 is not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind. None of the E-Fit EF-1280 training programs is designed for injured or alling muscles and its use on such muscles is contraindicated.
The E-Fit EF-1280 electrical impulses allow the triggering of action potentials on motoneurones of motor nerves (excitations). These excitations of motoneurones are transmitted to the motor endplate where they generate mechanical muscle fiber responses that correspond to muscle work. Depending on the parameters of the electrical impulses (pulse frequency, duration of contraction, duration of rest, and fotal session duration), different types of muscle work can be imposed on the stimulated muscles.
The various types of muscle work that the E-Fit E-Fit E-1280 can impose on the stimulated muscles are able to improve or facilitate muscle performance. The E-Fit EF-1280 may therefore be considered a technique of muscle training.
