Wireless Device Provides Drug-Free Pain Relief

An over-the-counter medical device based on transcutaneous electrical nerve stimulation (TENS) offers safe, effective, drug-free pain relief.

The Omron Healthcare (Kyoto, Japan) Avail device is designed is designed to provide symptomatic relief and management of chronic and acute pain, as well as relief from pain associated with arthritis or with sore or aching muscles due to strain from exercise or normal household work activities. Five pre-programmed body pain modes soothe lower back, shoulder, knee, elbow, and leg pain with recommended therapies, and users can also design their own therapies.


Five pulsation categories, including steady, acupuncture-like, knead, tap, and micro-current modes are available in 20 different intensity levels. The Omron Avail comes with two soft, contoured pads that fit comfortably and securely to treat pain at multiple sites simultaneously. To facilitate treatment delivery, the device is controlled by a mobile app called Omron TENS, which enables on-the-go personal control of pain relief using Bluetooth connectivity. The Omron TENS app for smartphones is available on the Apple App Store and Google Play.

“Pain sufferers are already inconvenienced by their condition. Avail is our new offering to bring accessible, convenient, portable drug-free pain relief to those who need it,” said Carol Lucarelli, director of marketing and product development for Omron Healthcare. “Omron created Avail with wireless capability to restore their freedom of movement while they get pain relief; and with two separately programmable TENS devices, the Omron Avail allows for customizable, multi-site treatment for individual aches and pains.”

TENS is one of the most commonly used forms of electroanalgesia for various types of conditions, such as low back pain, myofascial and arthritic pain, sympathetically mediated pain, bladder incontinence, neurogenic pain, visceral pain, and postsurgical pain. TENS produces neuromodulation by presynaptic inhibition in the dorsal horn of the spinal cord, endogenous pain control via endorphins, enkephalins, and dynorphins, direct inhibition of an abnormally excited nerve, and restoration of afferent input. The mechanism of the analgesia produced by TENS is explained by the gate-control theory.
