This is a method of using medium or higher alternating current frequencies to affect nerve function and, therefore, be used to detect, diagnose and treat nerve pain.

This is a method for identifying and then heating specific nerves, causing pain in the spine or major joints.

These are usually carried out under some form of image guidance, either ultrasound or x-ray guided and occasionally under CT.

Facet joint pain is one of the most common causes of neck and back pain. This condition can be diagnosed and treated by injections in selective cases.

These joints are at the back part of the pelvis and are implicated in very low back pain. They respond well to steroid injections to facilitate rehabilitation but are also amenable to radio-frequency denervation.

These are used to detect and treat pain from nerves and joints outside the spine, often associated with headaches, pelvic and groin pain, or pain in the major joints.

This is carried out as an intravenous infusion for a minimum of one hour. The aim of the treatment is to desensitise nerves that cannot be treated locally by injection.

This is used to treat persistent pain from muscle spasm or for prevention and treatment of migraine and will usually often provide several months of relief.
