There is a very simple exercise you can do to illustrate the continuity in the Superficial Back Line myofascial chain between gastrocnemius and hamstrings.
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.
Pelvic musculature: 1. cross the LS joint onto the trunk 2. cross the hip joint onto the thigh/leg 3. pelvic floor muscles located wholly within the pelvis
An adductor strain, also known as a groin pull in lay terms, is a strain of the musculature that does adduction of the thigh at the hip joint.
