Why the Right Psoas is Listed Under Frontal Plane Movement…I have been reviewing the anatomy families from the Advanced Integration course. The right psoas major and minor are listed under the frontal plane with adduction. I know that we want to recruit the right psoas muscle to assist with lumbar rotation to the left, but that would be in the transverse plane. It is also an external rotator of the femur, but that would also be in the transverse plane. I am having some trouble with what it would be doing in the frontal plane with adduction in a Right AIC pattern? Is this to assist with better positioning of the femur for FA ER in conjunction with the right glute max? You are correct in looking at the psoas musculature as a rotator (transverse plane). We engage this muscle group for that reason, especially in patients who have difficulty finding, feeling or experiencing complete left AF IR. But this muscle is listed in the Advanced course because we’re using it in the frontal plane to assist with right hip AF adduction and left thoracic abduction. If you refer to the Impingement and Instability course, you’ll see the left IC adductor, right serratus anterior and left IO/TA’s under frontal plane adduction and not the right psoas group. In the Advanced Integration course the psoas group is to remind us that as a transverse muscle group it has frontal plane influences on the Right AIC pattern when considering integrated right rib cage raise with right serratus anterior, left hip raise with left adductor and lumbar movement to the right for left thoracic abduction. |
