Analgesic Effect of a Prototype Device of Virtual Reality in a Population of Patients With Chronic Low Back Pain

Chronic low back pain and sciatica in adults represent a major medical and economic problem. During the chronic back pain (persisting continuously over 3 months), therapeutic responses to conventional pharmacologic type are often ineffective and the impact of pain is often heavy in terms of disability, social and professional avulsion and loss of quality of life. This failure has led in recent years to propose innovative strategies such as application of relaxation therapy techniques. An example is a virtual reality which is a technology to immerse someone in a 3D virtual environment. Our hypothesis is that the hypnotic suggestion combined with virtual reality can be effective on chronic pain. The main purpose is to measure the impact on the intensity of pain at 4 months after using of a new method for virtual environment, mimicking the colors from low to high frequencies (World Patent Filed, WO2007/057601) in patients with chronic disabling low back pain and sciatica resistant to therapeutic drugs.
