Inversion tables are downright magical if you believe some of their write-ups and ads. The tables reportedly do everything from clearing out your lymph system to killing off your motion sickness with improving your cellular heath in between. As with many forms of alternative therapies, the supposed benefits of inversion tables outweigh the scientific evidence that proves such benefits. That does not mean, however, that some basic facts don't hold up.
The Undisputed
One fact that cannot be disputed is that inversion tables make use of the force of gravity on your body. You hang upside down at your chosen angle while gravity goes to work. This work includes stretching you in the opposite direction to which you are accustomed and temporarily lengthening your spine, Mayo Clinic and Spine Universe report. All the pressure that normally pushes down on your spine, muscles, ligaments and other body parts when you are in an upright position is reduced if not altogether removed while you're hanging around on your inversion table.
The Table
Modern inversion tables generally come on a triangular metal frame that supports the rotating table top. You lie flat on your back, secure your feet beneath a cushioned bar and voila -- you can turn yourself upside down with a built-in control, usually handles you adjust while lying on the table. While you can buy cushioning pads, or even vibrating cushioning pads, most tables offer the same amount of padding as your average weight bench. Some offer additional neck support. Prices in late 2010 ranged from about $240 to $800 or more, depending on the features, and they are available at some medical and health equipment retailers.
The Risks
While inversion tables might provide relief from back pain, that relief is not going to last, Mayo Clinic warns. Because they increase your blood pressure and lower your heart rate, they can also be detrimental for certain conditions, specifically high blood pressure, heart disease or glaucoma. Other eye conditions can make inverting a risk, as can obesity, pregnancy, hernias, osteoporosis, spinal injuries and middle ear infections, Spine Universe adds. Always consult with your doctor before starting any form of therapy, including inversion.
The Kickoff
If you do decide to go for inversion therapy, don't hop on a table and immediately hang upside for hours on end, Spine Universe warns. Start slowly and test the table with a very slight angle of about 15 degrees for your first session. Most people don't go for a fully upside-down position, but rather hang at an angle of no more than 60 degrees. You don't need to hang fully upside-down to feel the effects of the table or use it as therapy. Inversion is best as a supplement to an overall back treatment plan, Mayo Clinic notes, and not as a sole remedy for your ailments.
