## 7. Device Description

The subject device is a self-adhesive TENS device with 15 adjustable intensity levels for pain relief. Moreover, it also provides a heat function which can be used alone, or in conjunction with the TENS function simultaneously. TENS, Transcutaneous Electrical Nerve Stimulation, refers to the electrical stimulation of nerves through the skin which is an effective method of pain relief. It can be used for self-treatment. Any symptoms that could be relieved using TENS must be checked by your general practitioner who will also give you instruction on how to carry out a TENS selftreatment regime.

TENS device works by passing electrical currents over the skin via a set of gel pads. As a transfer medium, the gel pads are subject to natural wear and tear, and must be replaced when they stop providing sufficient contact or the main unit no longer sticks to the skin completely. Failure to replace the gel pad may lead to skin irritation as a result of heightened current density in particular areas.

This device is only compatible with the 50 mm x 56 mm gel pads which are the OTC medical device cleared by FDA under K132588, and come with the device.

### 8. Intended Use / Indications for Use of the Device

The subject device is designed for symptomatic relief and management of chronic pain, and for temporary relief of pain associated with sore and aching muscles in the shoulder, waist, back, neck, upper extremities and lower extremities due to strain from exercise or normal household work activities. It is also indicated for temporary relief of pain associated with dysmenorrhea (menstrual cramps) when used with over-thecounter pain medication. In addition, it also provides a heat function intended to temporarily relieve minor aches and pains.
