However, postural distortions can result throughout the body if the Righting Reflex is obstructed.
Common causes of obstruction are:
In order to maintain postural homeostasis, the body is continuously compensating, keeping itself balanced over the feet and its head over the cervical spine with the eyes level to the horizon. The following simple experiment demonstrates this automatic, subconscious postural reflex:
Move your hip to one side
This automatic reflex (tilt in posture) maintains your head over your cervical spine, your eyes level to the horizon and your weight over your feet.
Lovett (1905) described a coupling of motion between the Pelvis and Cranium (Levett Reactor), and between the vertebrae (Spìnal Coupling):
Pelvic-Cranial Coupling (Lovett Reactor)
In essence, the Lovett Reactor is a description of what occurs in the pelvis, vertebrae and cranial bones when the Righting Reflex is working correctly.
