participant is laying on the left side, the practitioner stands in front of the participant's abdomen. The practitioner contacts the interspinous space of the L5-S1 level with the caudal; with the cephalic hand, the practitioner rotates the participant's upper body until a sense of tension is palpated at the L5-S1 segment. The practitioner places his cephalic hand at interspinous, brings participant's leg to a flexion and places the foot at the popliteal fossa, places the forearm at the participant's deltopectoral groove and the caudal forearm at the gluteal region. Following the participant's expiration, the practitioner brings the L5-S1 level to the restrictive barrier by rotating the trunk and hips to opposite directions.
