,By approximating the patient's knees to the abdomen in a knee-chest fashion (ankles crossed), the lumbo-pelvic musculature was stretched in the sagittal plane, by both the primary and first assist, contacting the base of the sacrum and raising the lower torso cephalad, resulting in passive flexion of the entire lumbar spine and its holding elements beyond the elastic barrier of resistance
