Inversion table therapy can relieve back pain by stretching the spine and surrounding area by going against gravity, which pulls everything down. It might also benefit general health by stretching the muscles and ligaments and improving circulation, according to SpineUniverse.com, a website that compiles information from spine experts. This treatment, however, might not be appropriate in certain instances. You should check with your doctor before using an inversion table.
Eye Damage
Inversion table therapy can increase the pressure in your eyes, and the steeper the angle of recline, the more intense the pressure. This can cause serious problems if you have conditions that affect your eye, such as glaucoma, retinal detachment or diabetic retinopathy. Teeter Hang Ups, a company that manufactures inversion tables for both personal and clinical use, cautions against using these tables if you have these types of conditions. The increased pressure can lead to burst blood vessels and other complications.
Changes in Blood Flow
This therapy produces changes in blood flow. SpineUniverse advises against using inversion therapy if you have heart or circulatory conditions. The altered blood flow could also prove dangerous if you have high blood pressure or take drugs to thin your blood, such as warfarin. These changes also preclude the use of this machine if you are pregnant, as it can reduce blood flow to the fetus.
Dangers to the Bones
Do not use inversion therapy if you have conditions like osteoporosis, skeletal implants, spinal injury or recently suffered a fracture. This therapy could put undue pressure on the bones, leading to breakage and other types of injury.
Other Problematic Health Conditions
Using an inversion table if you have inner ear problems can cause dizziness and other discomfort. You should also refrain from using this therapy if you have a hernia, eye infection or have suffered a stroke. Teeter Hang Ups also advises against use if you suffer from obesity, as you might suffer from undetected health problems that could make inversion therapy dangerous. As in any other instance, check with your doctor before using this technique.
