The TFL and VL are listed as part of the AIC pattern, but the rectus femoris and sartorius are not. In the Pelvis Restoration course, it is the rectus femoris and sartorius that are mentioned as the ones to inhibit on the left side, and activate on the right to pull the right inlet forward. I don’t see much mention of the TFL/VL in the exercises, though it is mentioned heavily as one needing inhibited. Any explanation there?
The TFL and VL are part of the polyarticular AIC chain. The Myokinematics course goes more in depth into FAIR/FAER relationships to inhibit the VL and TFL. The Pelvis course focuses more the iliacus muscle portion of the polyarticular AIC chain and goes more in depth into AFIR (IPIR/IsPER) and AFER (IPER/IsPIR) position to facilitate and inhibit the proximal fibers of the iliacus muscle. The Sartorius/Rectus Femoris muscles on the left and right side proximally influence the AFIR/AFER position, but are not part of the AIC polyarticular chain of muscle. As you know, many PRI exercises are integrating all of the concepts and science from the primary courses (Myokin/Pelvis/and Postural Resp.) and this is discussed more thoroughly in the Advanced Integration Course. For example, if your patient is doing the Right Sidelying Supported Hemi 90-90 taught in the pelvis course the left iliacus muscle is being facilitated on the left side for AFIR positon thru the pelvis and the femur for FAIR. So I am facilitating the left iliacus proximally while inhibiting both the VL and TFL thru FAIR facilitation of the anterior glute medius. Again, the concepts have to be broken down into the primary courses due to time constraints and introducing PRI, but are discussed further in the Advanced Integration course.
It seems, when one has a patient that needs the Pelvis Restoration sequence, because the adduction drop is negative now, but they still have a + PADT or PART, one could take them to a very good place using the pelvic sequence detailed by Lori Thomsen, without ever having to go back and do the Myokinematic Restoration algorithm. They have many points in common of course, but it seems that I may never use the myokin sequence put out, since so many patients seem to have a pelvic issue as well. Any thoughts on that?
The Myokin sequence is important if your patient is having difficulty facilitating or inhibiting FAIR/FAER and the Pelvis Course sequence is important if your patient is having difficulty achieving AFIR/AFER. Truly, integrating concepts taught in both courses with PRI objective tests will enable you to pick the best PRI activities for your patient. I feel patients advance quicker thru integration of all of the Primary Courses.
