The Shear Truth
As if all this wasn't enough other forces come into play to create a low back that is less stable and more prone to create chronic pain and discomfort. Shear forces to be exact.
In a person with normal posture, downward Gravitational and directional shear forces work with the body to "lock" joints into position under load, thereby providing strength and stability to the spine. In a pregnancy posture, the Gravitational forces remain essentially the same, but the shear forces change direction in such a way as to open the low back joints, providing less stability in the spine. The body's exquisite feedback system senses this and the muscles in the low back become tighter in an effort to take up the slack.
Treatment Options
Because the pelvic and spinal changes are so predictable, it is possible to map which muscles will undergo "Stretch Weakness" and which will exhibit "Short Weakness". With that knowledge, a health care professional can create an exercise program to strengthen the muscles that have become stretched, and a stretching program for the muscles that have become shortened.
However, all exercise programs suffer from the same problem; long term compliance. A pregnancy exercise program is at least a nine month process, and let's faces it, we are a Country that is easily bored. Especially with things that are good for us. Recently the author discovered a new therapeutic cushion that duplicates the effects of the most commonly prescribed exercises for pregnancy related back pain. It's called Posture Pal®.
Gravity Works Against You All Day Long.
Now, Make It Work For You!
The special contours and foam density of the Posture Pal cushion causes the person's body weight, along with the pull of Gravity to stretch muscles that need to be stretched and relax muscles that need to be relaxed. Imagine an exercise program that works by you doing nothing except lie on the floor!
