A small literature has examined electrophysi-ological activity in the context of rheumatoid arthritis and low back pain. Regarding rheumatoid arthritis, research suggests that patients, in comparison to healthy control participants, show larger amplitude N1 and P2 responses following repetitive, painful stimulation (Hummel et al, 2000). While patients' neural responses to stimuli were significantly different from controls, patients and control participants showed similar responses as measured by a peripheral index of pain sensitivity. This was taken to indicate that central influences may play a primary role in the experience of pain in rheumatoid arthritis patients. Finally, continuous EEG recordings measured in patients with low back pain who received heat therapy showed decreased power in the beta-1 and beta-2 frequency bands in comparison to low back pain patients who received analgesic treatment (Kettenmann et al, 2007).

Thank you for deciding to learn more about the disorder, Osteoarthritis. Inside these pages, you will learn what it is, who is most at risk for developing it, what causes it, and some treatment plans to help those that do have it feel better. While there is no definitive “cure” for Osteoarthritis, there are ways in which individuals can improve their quality of life and change the discomfort level to one that can be tolerated on a daily basis.
