First wireless back pain devices approved in U.S.

The WiTouch and WiTouch Pro are the first wireless remote-controlled devices to use transcutaneous electrical nerve stimulation for back pain. No, they have nothing to do with the Wii.

The WiTouch retails for $149. Hollywog

If you're in need of a little back pain relief and have $149 to spare, keep an eye out for the newly approved WiTouch by medical device developer Hollywog.

Putting a fresh spin on old tech, the device employs electrical stimulation (called transcutaneous electrical nerve stimulation -- aka TENS) to ease back pain. But unlike its predecessors, this one is wirelessly remote controlled.

There are two devices. The WiTouch is cleared by the FDA for over-the-counter use, and its bigger brother the WiTouch Pro is cleared for prescription use and comes with intensity controls on the unit as well as a remote. (Neither has anything to do with the similarly spelled Wii.)

With the small remote control, users can increase or decrease the level of electrical stimulation to their lower backs throughout a typical 30-minute session. Hollywog, based in Chattanooga, Tenn., says that even though the devices are small, they boast a 20 percent higher intensity output than similar portable devices and treat 2.5 times more area.

Without wires, belts, or wraps of any kind (replaceable gel pads keep the device in place), not to mention drugs, the green-winged gadget is pretty dang cute, and the batteries are supposed to last for 150 30-minute treatment sessions.

While it may only provide symptom relief and not actually treat back problems, WiTouch could be an elegant solution for those looking for discreet relief without resorting to drugs. It's retailing for $149 on the company's distributor site, Core Products, with orders starting to ship on Thursday, September 20.
