The story behind the invention of one of the most successful device in treating localized and chronic pain, IceOtherm from


Relief and Management of Chronic Pain – IceOtherm

Relief and Management of Chronic Pain – IceOtherm, which is being sold through in India, has been proven to be most successful in treating localized and chronic pain.

John Saringer, professional engineer developed the easy to use, easy to maintain, precision engineered IceOtherm. The IceOtherm is a hand held device which harnesses the Thermal Grill anomaly. By applying both mild heat and cooling to the areas of chronic pain, an intense stimulation is created (a paradoxical burning sensation), blocking and confusing the pain messages going to the brain. A ceramic core cools the center of the treatment surface to 25 degrees C cooler than the outside collar while the outer collar heats up to 42 to 48 degrees Celsius. The unit takes approximately 5 minutes before the collar warms up to reach peak therapeutic levels.


Relief and Management of Chronic Pain – IceOtherm

Canadian Engineer and successful inventor of medical devices, John Saringer, began to study the effects of heat and cold for the temporary treatment of pain, in the early 1990’s. He observed that there were many devices available on the market designed to provide some kind of sensory stimulation that will distract a person from their pain, or will interrupt the pain pattern. Noting that both heat and cold treatment products have been proven to be very effective sensory stimulators, he observed that “contrast therapy”, or the sequential application of heat and cold, proved to be more effective than heat or cold alone. John Saringer’s contribution to this field of investigation was the enhanced pain relief control that came from the “concurrent” application of heat and cold.

After developing over twenty prototypes John Saringer arrived at the optimum combination of heat (around the perimeter of the head of the device) and cold (on a small ceramic tile located at the centre of the head of the device). On May 13, 1997 John was awarded U.S. Patent # 5,628,769, Method And Devices For Producing Somatosensory Stimulation Using Temperature.
The innovation behind the IceOtherm.

The IceOtherm is a class II medical device designed to engage the body’s natural healing abilities using both hot and cold stimuli. The interlaced hot and cold stimuli, induces a paradoxical burning sensation known as the Thermal Grill Illusion. The Thermal Grill Illusion has been known to scientists for over a century, and was developed and first studied extensively by Thunberg in 1896. In scientific research applications, the thermal grill is used to create harmless sensations of pain.
