Comparison of Stabilization Exercises Versus Thrust Manipulation Technique on Pelvic Girdle Pain.

The program was based on specific training of the transversely oriented abdominal muscles with coactivation of the lumbar multifidus at the lumbosacral region, training of the gluteus maximus, the latissimus dorsi, the oblique abdominal muscles, the erector spinae, the quadratus lumborum, and the hip adductors and abductors. Initially, we focused on the specific contraction of the transversely oriented abdominal muscles. After approximately 2 weeks, loading was progressively increased throughout the intervention period. The women were required to exercise for 30 to 60 minutes, 3 days a week, for 3-4 weeks.

: For high-velocity thrust technique, a modified Chicago technique was used. For this procedure, the lumbopelvic region was targeted. The side to be treated was chosen, based on the subject's report of her most symptomatic side. The physical therapist, performed passively side bend the subject toward the painful side, rotate the upper body in the direction opposite to the side bending, and then deliver a quick posterior and inferior thrust at a grade V including a small-amplitude/high-velocity therapeutic movement. A maximum of 2 attempts per side was permitted if no pop was heard following the first attempt. If the subject showed improvement of 50% or less after the first treatment, the intervention was categorized as a failure, the examination and intervention were repeated, and the subjects were asked to return 2 to 4 days later. If the subject showed greater than 50% improvement, the intervention was categorized as a success, and study participation was concluded.
