How Your Feet Affect Your Spine and Back Pain
Sometimes the cause is obvious, such as sports injuries or bending methods. However, at other times, the cause may be surprising, such as when the culprit proves to be your feet and inappropriate shoes. When you walk, you apply five times the weight of each foot. If the foot does not absorb the shock or is properly redistributed, you may have problems elsewhere. This usually happens on people who have "flat feet" because the arches appear to be flat and closer to the ground.
Rotation refers to the inward movement of the foot, which causes the folded arch and flat feet as you stand, walk or run.
There should be a slight internal rotation for walking and running. This is a necessary exercise that allows the dynamic movement of the feet and ankles to reduce the impact of walking and running on the body. Excessive inward movement of the foot with super-inner rotation also causes the legs to rotate inward, affecting the knee, hip and lower back postures. This may be exacerbated when the foot varus occurs on only one foot, because it shortens the effective length of the leg (the distance between the hip and the floor) when the foot is rotated internally.
Another foot problem is the over-the-air cushion, in which the foot rolls outwards and looks like a high arch. Excessive rotation also causes the legs to rotate outward and put extra stress on the muscles outside the legs. High internal rotation or super external rotation can also cause problems in the buttocks and waist.
When you feel pain and you are diagnosed with foot or ankle dysfunction, you can reduce knee and hip pain by improving foot function and using appropriate footwear and orthopedic insoles.
