<>MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet. >
<>Dr. Richard Deyo, one of the great myth busters of low back pain research, believes that “low back pain is second to upper respiratory problems as a symptom-related reason for visits to a physician” — only the common cold causes more complaints. Hart et al puts low back pain in fifth place (lower because Hart oddly excludes chronic low back pain). Chronic low back pain is usually the kind that this book will examine. Andersson writes: “Although the literature is filled with information about the prevalence and incidence of back pain in general, there is less information about chronic back pain … .” Indeed, it is almost impossible to measure how much chronic low back pain there is: for every time that acute low back pain is the main reason for a visit to a physician, how many times does a patient mention low back pain as a secondary problem? Or sees an alternative health care professional about it instead? (Answer: pretty danged often.) So it’s actually possible that low back pain is the single most common reason that people seek help.

<>2016 — Science update: There is now a good scientific concensus on the subject of spinal fusion, thanks to papers like Mannion 2013 and Hedlund 2016. Putting a spotlight on this called for some serious revision and editing. The whole section is greatly improved.

<>2010 — Updated: Added a very beefy footnote about some new research showing that muscle imbalance does not result in higher rates of injury. This almost should have been a new section, but I decided to just make it a ginormous footnote — footnotes are there for delving if you want to, that’s the idea! You can read a summary of the research in the bibliography (see Hides et al), but the relevance to back pain is spelled out in detail here. And it’s interesting.

<>There are two kinds of over-the-counter pain relievers that frequently help with back pain: nonsteroidal anti-inflammatory drugs (NSAIDs) and acetaminophen. Both have some side effects, and some people may not be able to take them. Talk to your doctor before taking pain relievers. And don't expect medication alone to solve your pain problem. Studies show you'll probably need more than one type of treatment. >
