Sacroiliac Joint Mechanics, Assessment and Treatment: A Bicondylar Commentary and a Randomized Trial of Core Stability With Mulligan Mobilization

Physical therapists and physical therapist assistants who evaluate or treat patients with low back and posterior pelvic pain and want a plain-language account of the current thinking on sacroiliac joint mechanics alongside the trial evidence for core stability exercise and Mulligan mobilization with movement.

Physical therapists and physical therapist assistants. Athletic trainers, occupational therapists and chiropractors working with low back and pelvic pain may also find the material relevant.

Intended audience

After completing this course, you will be able to:

1. Describe the bicondylar paradigm proposed in the JOSPT Open clinical commentary, including the authors' argument that the two sacroiliac joints move together as one functional unit rather than independently.
2. State what the randomized controlled trial reported in Frontiers in Physiology found for pain, disability, lumbar range of motion, pressure pain threshold and pelvic tilt asymmetry after six weeks of core stability exercise alone and combined with Mulligan mobilization with movement.
3. Distinguish expert opinion from trial evidence when explaining what the two papers together support about sacroiliac joint examination and plan of care, and where they diverge.
