The therapist places his knees (as close as possible) over one side and the other of the lumbar spine and then he closes, as much as possible, the angle between the calves and the thighs. The knees are rolled from the interior to the exterior for about 10 times. The weight of the therapist is distributed symmetrically on the knees. The patient’s constitution and health must be taken into account, as well as the ratio between the therapist’s and the patient’s weight. The patient’s thorax is properly secured by providing a rigid support surface.
