First of all, big shoutout to Jacob Grams and Jeff Wolf. These guys helped me understand the gait mechanics behind things I had been observing for years. Without their contribution, I would have never been able to help myself and countless others resolve their limitations. Second of all, PRI is a useful point of inquiry for movement pros. Despite my disagreement with their description of the left AIC pattern and pelvis, their approach helps you look at movement in 3 planes. This is helpful and I encourage you to look at their upcoming courses on their website. With all this said, I believe PRI has the pelvis backwards. And the reason is because of a flawed understanding and description of gait. PRI describes the left AIC pelvis as oriented to the right and stuck in "right stance." The pelvis appears hiked on the right relative to the left. This is the justification for activities that turn the pelvis to the left to achieve left AF IR, a "left stance" position. But shifting the pelvis in the frontal plane and turning the pelvis in the transverse plane do NOT happen during the same phase of gait. And so, the logic of left transverse plane activities to resolve a right frontal plane pelvic orientation falls apart. In early right stance/loading response, the pelvis hikes up on the right int the frontal plane and turns (is turned) back to the left in the transverse plane. In true right mid stance, the left leg swings, the left hip hikes in the frontal plane and the pelvis turns towards the right in the transverse plane. Achieving true right mid stance "resolves" the right hip hike and frontal plane shift. Turning the pelvis to the left, as in left AF IR activities, reinforces a tendency to avoid achieving true right mid-stance. In this way, PRI has their description and interventions of the pelvis backwards. The goals should not be to push away from the right and towards the left. In fact, they should be the opposite. These are the correct goals: 1. Push away from the left in the transverse plane (left pronation) 2. Allow a left hip hike in the frontal plane (left pronation) 3. Shift over the right hip in the transverse plane (right supination) 4. Allow a right (relative) hip drop in the frontal plane (right supination) To get these changes to stick, implement specific cues into your lifting activities. If I have enough interest, I'll make a group program. Comment FLIPPED below.
