Do you have any information on inversion boots? Are they safe, effective or none of the above?
Although early research indicated inversion therapy increased blood pressure and internal eye pressure, later research shows you are at no more of a stroke risk hanging upside down than if you are exercising right side up, and inversion therapy is not a risk to normotensive healthy subjects. In fact, there has never been a documented stroke or cardiovascular incident resulting from inversion. Even the Army Rangers at the US Army Physical Fitness School at Fort Benning use inversion as part of their training. Numerous studies have shown inversion to be effective stretching paraspinal vertebral muscles, reducing disc protrusions and relieving pain related to spondylolisthesis, herniated discs and lumbar osteoarthritis.
In short, the evidence indicates inversion therapy to be both safe and effective.
