This particular situation originates usually at the top of the sacrum then, begins gradually traveling up the spine. Of course this isn't the only reason for the diagnosis, but this is when the Sacro Wedgy® may be of some help.
The muscle called the psoas begins to become tighter and shorter on one side and since it is attached to the spine, the tight muscle begins to torque or pull on one side of the spine. This in turn creates a slight curve. The reason the Sacro Wedgy® has helped people with this is because the psoas muscle now has a chance to start relaxing. The psoas muscle is a long muscle that starts at the twelfth thoracic vertebrae, travels down the back then crosses the front of the pelvic bone and inserts deep into the front of the thigh.
We also have a series of isometrics to strengthen the weaker psoas muscle. If one side is tight and short, the other side will be weak and long. "Make the longer stronger." It's very important that you always address both sides of the body and when relaxing on the Sacro Wedgy® and neck support, that is exactly what you are doing.
