The PainKARE is indicatied for Temporary relief of pain of sore and aching muscles, joints, and tissues due to strain from exercise or normal household and work activities.
Device Story
PainKARE is an OTC transcutaneous electrical nerve stimulator (TENS) for temporary pain relief. The device consists of two stimulator pads connected by a USB cable. It operates via a microprocessor-controlled system that delivers biphasic electrical waveforms to the body. The device is powered by a rechargeable battery. Users operate the device to provide electrotherapy, with adjustable treatment times ranging from 30 minutes to 4 hours. The device includes safety features such as automatic overload protection, automatic no-load alarm, and automatic shut-off. It is intended for use by individuals to manage pain from muscle or joint strain. The healthcare provider or user monitors the device status via an operational indicator. The device provides a non-pharmacological method for pain management.
Clinical Evidence
Bench testing only. The device was tested for electrical safety and electromagnetic compatibility per AAMI ES 60601-1, IEC 60601-1-2, IEC 60601-1-6, AAMI HA60601-1-11, and IEC 60601-2-10. No clinical data was provided.

Dear Ms. Chansoria:
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.
