It should never be assumed that hip shifting ability is symmetrical on the left and right hips. Athletes positioned in a Left AIC pattern are remaining in a shifted state on the right hip. They never shift into the left hip despite transferring weight to the left lower extremity. How do athletes accomplish this? They are compensating with excessive ball (femur) rotation which often results in extreme overuse of the hip flexors and lateral quadriceps. The left glutes and left inner thighs, the primary hip shifting muscles, adaptively become very weak because they are used less and less as the athlete continues to compensate around their right leg dominance. As left hip shifting (AF IR) ability is lost, the compensating muscles can pull the ball away from the socket until they are no longer congruently aligned. With hip stability compromised, the athlete is predisposed to abnormal joint forces and pain through the feet, knees, hips, and back.
That pretty much could be the best summary of my past 25+ years trying to run out of pain and imbalances and the frustrations often expressed on this blog because I could never find a therapy that would help me recover my stride.
Postural Restoration seems to be doing it for me and I just keep hoping things will get better and better. I feel I have gone from about 30% efficieny to about 80% efficiency since I found Postural Restoration and I keep adding a bit of efficiency each week as I tweak and manage things on my own.
