SAGITTAL ALIGNMENT OF SPINE REGULATED BY PELVIC INCIDENCE: A REVIEW

The present paper is not only a review of the literature on pelvic incidence parameter, is also designed to reflect anew to the actions of preventive and compensatory physical activity, with particular reference to abdominal exercises. The incidence pelvic anatomy is a parameter whose value represents the angle between the perpendicular to the sacral plate at its midpoint and the line joining this point to the axis of the femoral head; it controls the spinal curves in accordance with the adaptability other parameters. The studies analyzed here suggest new considerations to be applied in the dynamic execution of preventive and compensatory physical activity. The training of the muscles lumbar and abdominal represents a key point for the maintenance of right posture and for the appropriate discharge of the forces on the spine. In both cases the changes of normal range, high or low incidence of pelvic exercises must be interpreted differently.
