Dynamic stabilization of the trunk.

The lumbopelvic region, because it is the hub of our antigravity weightbearing, is the most vulnerable area for spraining and straining tissues. It is also, however, the most difficult area to treat because of our inability to completely control the healing of these injured tissues. Properly identifying and accurately assessing the biomechanics of injury and understanding the basic science of the processes of soft tissue healing are critical in order to initiate proper goal-oriented treatment geared toward regaining normal function of the injured area. If normal function is not restored, frequent reinjury and chronic symptoms often occur. Because of the background and the knowledge in anatomy, biomechanics, and kinesiology the physical therapist is the most qualified to begin a program geared toward properly managing this region. Unfortunately, too often it is a decrease in overall fitness as well as asymmetrical skeletal forces that predispose the lumbopelvic region to injury. That is, it is almost as if these people are "accidents waiting to happen. " Attempting to undo that which has been progressing for years is a difficult problem for those who treat lumbopelvic pain. This paper sets forth one rational approach for effectively stabilizing and treating these conditions. J Orthop Sports Phys Ther 1985;6(5):271-277.
