When the way you walk and stand is less than perfect, every step you take places stress on every joint, muscle and nerve in the body. That may be just a little difficult to believe, but it is fully explained by the science of human biomechanics. In fact most every “over use syndrome” that results in chronic pain located in the foot, knee and spine is caused by excessive pronation (arch break down) and internal rotation (knocked knees) of the legs.
As both legs are rotated inward with improper gait, the pelvis is tilted forward. In the same way that a level foundation is important to the structural integrity of the house it supports, so is the tilt of the pelvis related to the curvatures of the spinal column. As the pelvic platform tilts forward both lumbar and thoracic curvatures increase. This forward tilt results in what is commonly referred to as “sway back” and “hump back” in the general population.
When a history of injury is present and weakness to the joints of the body occurs, the constant stress as you walk and stand results in chronic irritation, inflammation, and eventually pain with every step you take. Long before this chain reaction that starts at the foot and ends in the neck were expressed in scientific terms, everyone knew that the foot bone is connected to the leg bone, and the leg bone is connected to the hip bone, and the hip bone is connected to the back bones.
Hundreds of internet sites describe how postural breakdown is the cause of pain throughout the entire body. Many understand that problem begins with foot function, while others try to strengthen the muscles and manually realign the position of the joints with exercise and physical therapy.
