PPC/OMM Block 6 Practice Exam

When movement below the diaphragm is reduced after pelvic or abdominal trauma, the body tends to guard and limit motion in that region. The abdominal wall shows little excursion during breathing, and the pelvic floor muscles often become inhibited or fail to move effectively, leading to minimal abdominal motion and an absence of pelvic floor motion. This reflects decreased motor activity and fascial glide in the lower trunk, as well as reduced muscular support for core function. Because trauma and immobilization blunt movement and the muscle pump that aids circulation, options suggesting increased motion, rapid lymphatic flow, or improved respiratory efficiency don’t fit the expected response.
