Even though you do not realize, most likely, you are limping too. Because most people’s both tarsal joints fall in different degrees and angles, which makes one leg shorter than the other. With one leg shorter than the other, a person cannot avoid limping.
Limping means that your whole body is moving without the alignment; this means that your major weight-bearing joints are being damaged much faster.
In order to walk correctly without limping, first, both anklebones should be aligned at the same height with the proper orthotics. In most cases, with the proper orthotics, both leg lengths become the same immediately, and systematically, align the hip bones as well. With the same leg length, you cannot limp; though, you can pretend to be limping.
Treatment
The orthotics that align the ankle bones make the leg length the same. And walk correctly by transferring the body weight through the centerline of the foot; this can be done by bending the knee toward the second toe. When you walk correctly, the body weight spread evenly at the bottom of the foot evenly.
If you are over 60 years old, your leg length may not become the same due to thinned cartilage between the different joints and rigid ligaments/muscles around the misaligned joints; yet the leg length discrepancy reduces. While wearing orthotics, stretching the whole body in all different directions as often as possible can help the ligaments/muscles flexibility, and improve your posture little by little.
The majority of people who are obviously limping do not know they are limping unless someone tells them so; because they have been limping since they were toddlers. If you are limping, you might think that you are limping because your knees, back, hip, or wherever hurts. But if you use the orthotics that align the anklebones, you would not limp anymore and the pain that caused the limping might disappear.
Very few people are literally born with one leg shorter than the other for some reason. If you are one of them, after you find the right orthotics to align the anklebones, you should use a heel lift under the orthotic for the shorter leg to make both leg lengths the same. The height of the heel lift or the whole foot lift can be precisely measured by the two-feet anklebone alignment test. If the lift makes the leg length the same, you will pass the test.
Also, I have witnessed in my practice that people with cerebral palsy sway much less with the proper orthotics.
We measure the leg length from the bottom of the foot to the top of the hip bone. Therefore, the total leg length = the arch height + the leg length + the hip height. But when the arch falls, the whole leg length becomes a lot shorter than the height the arch that fell. Because on tilted anklebones, the leg, the thigh, and the hip stand in a zigzag pattern, this reduces the leg length much more than the height of the arch that fell.
