Impingement and Instability - (Indianapolis IN). Enjoyed a great weekend in Indianapolis with Bill Hartman and the IFAST crew exploring the secondary level PRI course Impingement and Instability. A big thank you to Bill and his entire staff for making me feel so welcome and for taking such good care of me throughout the weekend.
We started the course with an explanation of lateralization and the physiological and neurological reasons behind the lateralized tendencies seen with the Left AIC/Right BC pattern. We introduced a strong frontal plane approach to calcaneal performance and also to the gait cycle, emphasizing frontal plane ankle and hip strategies to help manage human lateralization.
We moved into a discussion of femoral orientation and compensation patterns that can destabilize the lower kinematic chain and cause problems with the tibial - femoral relationship. We talked about how these patterns can directly cause knee pain and knee dysfunction, and also talked about patterns that don't necessarily cause knee pain, but still need to be properly managed because they often contribute to problems in other areas. Thank you Bill for both your questions and your comments in this regard.
The second day included discussions about ilial instability and scapular instability. The relationship between the iliacus and the glute medius as functional performers for the pelvic inlet to stabilize the ilium in the frontal plane was discussed. As it relates to scapular instabilities, we looked at the frontal plane function of the low trap and compared it to sagittal plane function on both sides. We also evaluated the frontal plane function of the serratus anterior and compared it to the sagittal plane function on both sides. We finished our scapular Instability discussion with demos and overview of subscapularis as a true internal rotator of the shoulder joint once position and proper lateralization was established.
