All individuals have a pelvic floor, no matter the sex. Despite this fact, the pelvic floor has largely been left out of orthopedic, fitness, and sports education and assessment. Therefore, the pelvic floor is frequently thought of as a “taboo” region of concern that is discussed only during and after pregnancy.
ABOUT THE PELVIC FLOOR
Why is the pelvic floor important? The transversus abdominis (TrA) (Figure 1), diaphragm, pelvic floor muscles (PFM), and multifidus function together to provide spinal support by managing IAP (16). This system has been described by a variety of visual models including a cylinder, a soda can, and a piston (17). As described by Richardson et al. (18), the TrA serves as the wall of the system, with the pelvic floor as the base and the diaphragm as the top. The pelvic floor is the missing link in previous core discussions that ignore the bottom of the soda can. One study even concluded that the pelvic floor has a greater influence on low back pain compared with abdominal muscles (19).
