Innovative Device for Pain Management by Millimeter Band Radiation : Electronic-Pain Killer.

Innovative Device for Pain Management by Millimeter Band Radiation : Electronic-Pain Killer. Evaluation in Patients With Peripheral Osteoarthritis: A Single Center, Prospective, Randomized in Cross-over, Comparative and Open-label Study

In this study, in addition of conventional treatment, the efficacy of the medical device, Remedee One, in medical care of patients with peripheral osteoarthritis pain is evaluated.

Osteoarthritis affects 10 millions people in France (17% of the population). It's the second cause of disability and consultation after the cardiovascular diseases in France. For the moment, there is no curative treatment for osteoarthritis The main clinical sign of this disease is pain and care is based on the treatment of pain and on the improvement of functionnal disability. The proposed treatments are mainly based on the use of oral analgesics treatments .

At present, patients report to be insufficiently relieved. New strategies need to be developed. The hypothesis is that the use of an innovative medical device, Remedee One, can reduce the pain felt by patients, improve their quality of life and reduce the analgesics consumption.

The choice is oriented on the peripheral osteoarthritis and excludes spinal osteoarthritis because it's an osteoarthritis always asymptomatic and painless.
