Does inversion table work ?

Back pain can cause you a lot of discomforts, and when it gets worse, it can halt your normal functioning. One of the ways that are increasingly being used to treat back pain is Inversion Therapy.
The use of inversion tables, for instance, involves the patient adopting an upside-down posture aimed at reversing gravitational effects on the spine. Usually, the head will be tilted downwards on a table in a bid to relieve pressure on both the discs and nerve roots found in the spine.
The proponents of this therapy suggest that besides relieving back pain, inversion tables come with other benefits including an increase in flexibility, improved blood supply to the scalp and brain, relieving the varicose veins, etc.
When giving results from a study done by the New Castle University, The Energy Center reported that up to 75 percent of patients that frequently used inversion tables avoided invasive treatments like surgery. Back pains can be caused by fluids building up in the discs in your spine. Using inversion table can help to milk the fluid out thus reducing pressure in the spine. This is pain relieving.
Researchers have regarded the use of inversion tables as a form of Traction therapy. This kind of traction therapy (that uses inversion tables) has been proven to relieve muscle spasms by stretching the ligaments and muscles around the spine. While it also reduces the negative effects of gravity on the spine, traction also aids in the treatment of ailments like scoliosis (a condition involving the spine becoming abnormally curved), and sciatica (a condition that causes pain in the legs and hips as a result of pinched nerves in the spine).
A 1978 research suggested that using inversion tables regularly results in a lengthened spine and reduced muscle activities. This, the researchers said, relieves painful muscle spasms and stops painful forces on the spine.
However, using inversion tables has some contraindications. The use of inversion tables lowers the heart rate, increases blood pressure and raises the pressure in the head and eyes. Besides causing bleeding into the retina in some users, it can also result in blurred vision and headaches. For this reason, experts have advised that people with heart diseases, high blood pressure, glaucoma, and people with retinal detachments should not use inversion tables. Pregnant women should also avoid using them.
To sum this, it is important to note that, as a result of the stretching effect that inversion tables come with, you should not use them if you have fractures, spinal injuries or unhealed hernias.
