How Foot Orthotics Help Low Back Pain
For many, if not most, patients with low back pain, finding a treatment or combination therapy that provides effective pain relief is a trial and error process. Although the situation is similar between patients, most of the available treatments for low back pain do not always bring beneficial results to all patients. The same is true for the use of a foot orthosis.
Foot orthoses can theoretically help patients with back pain because they help to reorient the expression of the foot on the ground, affecting the overall posture and gait of the body. This process can be illustrated in the following manner. In a person with a normal arch, if an imaginary line is drawn down the tibia (tibia) to the foot, the imaginary line should pass between the person's big toe and second toe. However, if the same imaginary line is drawn on a person with a flat or too high arch, causing the foot and ankle to rotate inward, or to roll inward, the line will pass through the inside of the big toe. In people who have their feet and ankles turned, the change in weight will move to the outside of the foot, which can cause painful bunions and other problems.
Turning your feet and ankles can also cause your knees to turn inward, a condition commonly referred to as a knee. This abnormal placement of the knee then changes the angle at which the thigh bone meets the pelvis, resulting in an unstable hip posture, which also makes the spine unstable. The result is a domino effect from the foot that enters the pelvis and spine along the legs. Continuous alignment of the feet, legs, buttocks and spine while walking and standing can cause back pain.
Using a foot orthosis to re-adjust the back of the foot to prevent foot varus may help prevent this domino effect.
