The user lies on his back, totally relaxed, with knees bent over the device in a position known as the �Semi-Fowler� position. The device moves the lower back vertebrae in a regular circular motion (a motion known as �Anterior-Posterior Pelvic Tilt�). This forward movement, posterior pelvic tilt, performs a circular motion which levels the hip arch, gently releases the vertebrae, increases metabolism in that area, enhances blood flow, and enables the passage of oxygen and nutritional material while speeding up the disposal of waste products. This motion, first described by Dr Maitland, the father of modern physiotherapy, helps restore mobility to the patient and to their damaged tissues. At the same time, the repeated motion soothes pain sensors and facilitates the release of endorphins, which assist in providing relief. Click here for a full demo
