There are several methods of inversion therapy, but each one entails moving the body into an upside-down position. One form involves lying on a padded inversion table that slowly guides you into a head-down position while your body is securely strapped to the apparatus. Some back pain inversion tables used padded bars that you place your feet under rather than straps to keep your body fastened. Inversions tables are designed to stretch out the spinal cord via gravity that places force on the spinal cord. There are a number of pros and cons to consider before using an inversion table.
Pros
According to the Mayo Clinic, inversion therapy in general is intended to relieve gravity-induced pressure that is chronically placed on the nerve roots and disks in your spine and enlarges the space between vertebrae. Some people find temporary relief of back pain through the use of an inversion table and may be able to avoid or prolong the use pain medication. Inversion tables may also help to improve poor posture. They don't require assembly and are relatively simple to use.
Cons
Inversion tables don't appear to provide any long-lasting effects. The upside-down position may pose a risk for people who have a heart condition, high blood pressure or glaucoma. Back pain inversion tables are cumbersome and can be difficult to store, especially when space is limited.
Some people may dislike the feeling of hanging upside down and the sensation of blood rushing to the head. The safety straps may rub against the skin and cause some discomfort.
Precautions
When your body remains in an upside-down position for more than a few minutes, your heartbeat slows as your blood pressure rises. Therefore, you should not use an inversion table if you suffer from cardiovascular disease or elevated eye pressure. Inversion tables are also not recommended for people who have weak ankles. Talk to your doctor about your specific concerns before using an inversion table.
