No
The description focuses on standard TENS technology with pre-set modes and does not mention any adaptive or learning capabilities.
Yes
The device is intended for the "relief of pain associated with sore or aching muscles," which is a therapeutic purpose. It also falls under the category of T.E.N.S. devices, which are commonly used for pain therapy.
No
Explanation: The device is intended for pain relief and described as a T.E.N.S. device, which are therapeutic devices, not diagnostic devices. Its intended use focuses on symptom relief rather than the identification or measurement of a condition.
No
The device description explicitly states it is a "portable, battery powered T.E.N.S. device" and mentions accessories like "electrode cable and electrodes pads," indicating it includes hardware components beyond just software.
Based on the provided information, the EasyStim TN28 OTC device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Function: The EasyStim TN28 OTC is a T.E.N.S. (Transcutaneous Electrical Nerve Stimulation) device. It applies electrical signals to the skin to relieve pain. This is a physical therapy method, not a diagnostic test performed on a biological sample.
- Intended Use: The intended use is for pain relief, not for diagnosing any condition.
- Device Description: The description clearly outlines the device's function as applying electrical signals through electrodes placed on the skin. There is no mention of analyzing biological samples.
Therefore, the EasyStim TN28 OTC falls under the category of a therapeutic device, not an in vitro diagnostic device.

DIFFERENCES BETWEEN NEW DEVICE AND PREDICATE DEVICES
The technical characteristics of EasyStim TN28 OTC are similar to those of the predicate devices in design, energy source, intended use and function. Like the predicate device Model PM3030 (K110068) and EasyMed TN-28C T.E.N.S. Unit (K040253), the EasyStim TN28 OTC is a device used to apply an electrical current to electrodes on a patient's skin to relieve pain.
The stimulation parameters of new device EasyStim TN28_OTC are all in the same range of those of predicate device TN-28C(K040253) and similar to those of Model PM3030 (K110068). Furthermore, the designed circuitry of new device EasyStim TN28 OTC is very similar to the marketed device TN-28C (K040253), they are of similar circuit diagrams, similar working principle, and same plastic housing.
Some output characteristics of EasyStim TN28 OTC are different from those of Model PM3030 (K110068). However, the maximum phase charge (the charge delivered per pulse) of EasyStim TN28 OTC is 20.02µC, which is less than 25µC. On the other hand, the maximum average power density of EasyStim TN28 OTC is 0.00752W/cm², which is also less than 0.25W/cm². Furthermore, the frequency range of EasyStim TN28 OTC is from 1Hz to 150Hz, which is same as TN-28C(K040253) but different from Model PM3030 (K110068). But it needs 20 steps to reach up to the maximum output frequency (150Hz). Therefore, the differences between EasyStim TN28 OTC and Model PM3030 (K110068) are insignificant in terms of safety.
The EasyStim TN28 OTC is viewed as substantially equivalent to the predicate devices because: the electrical stimulation provided by the EasyStim TN28_OTC is substantially equivalent to that commonly employed by TENS devices that have been cleared for marketing without prescription labeling, i.e. for OTC use. The waveform combinations are restricted in amplitude and duration to values consistent with other cleared devices.
Technological characteristics, features, specifications, materials and intended uses of the EasyStim TN28 OTC are substantially equivalent to the predicate devices. The differences that exist between EasyStim TN28_OTC and predicate devices are insignificant in the terms of safety or effectiveness.

USABILITY STUDY:
A usability study was conducted and showed that users were able to use the device correctly and safety.
CONCLUSION:
The new device EasyStim TN28 OTC has the same indications for use and similar technological characteristics as the predicate devices Model PM3030 (K110068) and TN-28C (K040253). The stimulation parameters of new device EasyStim TN28 OTC are all in the same range of those of predicate devices. Thus, the new device EasyStim TN28 OTC is substantially equivalent to the predicate devices and any differences between the devices do not pose any new questions of safety and effectiveness.
