I was looking at material for the NASM certification, and under the section about postural distortions it describes a tight ITB as one cause of the “knock-kneed” appearance, along with tight adductors and weak glutes.
The adductors and glutes I understand, but I have trouble understanding why a tight ITB(and TFL) would cause the knees to be adducted? From what I can find, the ITB connects to the outside of the hip, and outside of the tibia. So, I would think that if it were tight, it would pull the knee out. Can some one please explain why a tight ITB/TFL causes knee adduction?
The only other guess I can make is that the knee adduction is the cause of the ITB tightness, and not the other way around. Is this correct?
