This blog discuss two types of leg length discrepancies: fixed leg length discrepancy and flexible leg length discrepancy. What are the different symptoms for each of these leg length discrepancy? Should you worry about having a leg length discrepancy?

The first type of leg length discrepancies you can have is a fix or anatomical difference. This means that one leg physically measures at a different length then the other leg. The trick to diagnosing this is having someone measure from the same fixed points on your legs and comparing the measurement.

The bodies way of adjusting of long term leg length difference is people find themselves standing on one leg more often or keeping one leg bent while the other might be fully or hyper extended. Or you might find that one foot may be flat and the other may have a normal arch.

The way to “fix” this would be to add a lift to the shoe of the shorter leg depending on the length difference.

But before you go buy some fancy new lifts for your shoes it is far more common for the length discrepancy to be from a rotation in your pelvis which begins us to the 2nd type of leg length discrepancy.

I was told in high school that one of my legs was 3 inches shorter then the other leg when I was assessed by a local practitioner. When I left their office miraculously my legs were the same length. I remember being so confused by how she could spontaneously make my leg grow. Well her fix was not permanent I was suppose to come back a several time then at some point the fix would just stay. Well I dont know if I finished the treatment but I stopped going and I still had to deal with the severe lower back spasms, not being able to lay flat and randomly limping.

Is that a similar story for you or someone you know? Please tell me about their story in the comments below!

Common symptoms for someone dealing with your pelvis being rotated are:

• Point pain in your lower back when you walk. Occasionally this pain can change sides from day to day.
• You might not have pain but have you notice that you have a dramatic difference in leg strength or form from one side to the other when you lunge.
• Your hips could wiggle side to side when you squat verses being able to make a smooth transition up and down.

How do you fix this? With a full physical and movement assessment of your legs, hip and stomach muscle strength and flexibility to ensure all these area are balanced.
