The authors suggested that experienced dancers demonstrate safer landing strategies compared to recreational athletes. Dance training experience may provide protection against high-risk movement patterns. And thus, dance training may be modeled to prevent ACL injuries.
So, if hip abductor group on one side is tighter at baseline tone than the hip adductor group on that side, the pelvis will be pulled into depression on that side, resulting in a lumbar scoliosis that is convex on that side. Similarly, tight opposite-side hip adductor musculature can cause the same scoliotic curve.
