Can We Just Forget Posture Then?
While energy draining, rigid postures are unlikely to be useful for prolonged standing. The effect of gravity on our bodies in standing should still be considered. We are all slaves to gravity and how we position our body segments relative to gravitational forces, has an inescapable influence on distribution of loads across our bones, joints, muscles and tendons.
Holding postures or repetitively moving the hip joint to the very extremes of its available range of motion will result in disproportionately high loading around the outer edge of the joint (edge-loading), and increased loads on the ligaments, muscles and tendons that support the joint. It’s simple physics really.
Whether this disproportionate or excessive load ever results in structural damage, pain or the ability to participate in normal daily or sporting tasks is another matter. In the development of pathology (structural damage or deterioration), multiple factors are usually implicated, and often different combinations of factors are at play for each individual. For some people, postural habits may play a key role in their hip and back pain; for others, it is irrelevant.
A thorough assessment by a skilled Hip Pain Professional will provide some insights as to whether posture is a contributor to your particular problem, and if so, what to do about it. They will help guide you to as to what is good posture for hip pain relief in your individual situation.
