Normal sagittal balance – The side view of the spine will demonstrate 4 normal curves. These curves are important to keep the head directly over the pelvis and to absorb shock with jumping and impact. This balance means that with standing, you can “rest on your ligaments”. There is minimal energy used to hold yourself up while standing. If your head is in front or in back of the pelvis with standing, the body needs to use muscle contraction to keep you upright. This causes back and neck pain from muscle overuse and fatigue.
