I read in a article of your and I just read "Bilateral obturator internus" and saw the muscle image on Google Images I immediately felt a deep discomfort, almost a panicky feeling, like a traumatic and painful memory that I wanted to get rid of immediately. Perhaps some childhood episode, perhaps a fall from a bicycle, perhaps an excessive stretch of this region. I feel like my brain doesn't want to use this left side region. So bad that brains learn bad things so easily and unlearn so hard.
Hey Regis, I'm sorry to hear that you experienced that. It's interesting how trauma can impact the things we feel, or even those who have been in pain for longer periods can actually feel different sensations without actually moving the area. Our bodies are wonderful at protecting in various ways, even if it's a counterproductive strategy now. The key point you mentioned is learn. Although we learn undesriable things, we can be adaptable to the point where we can learn more desirable things as well. The beauty of us!
Hello ZAc! Love the knowledge you'e dropping brother. Had a question: If the RIGHT side of the pelvis is in a anterior tilt, then the SI joint on the same RIGHT side would be higher or lower then the opposite SI joint? Cheers D
Hello Zac , at 11:25 you talk about the swing leg IR being restored , would this be because you are pushing with the inside arch to the left and this helps restore the IR on the swing leg? Thanks
Hey Zac! You said that we reach maximum IR @ the femur during Toe-Off. That makes intuitive sense to me because the pelvis keeps rotating on the femur (pelvis rotating to the left in your example) until we´ve reached Toe-Off...right? In Human Locomotion it says that we reach maximum ER @ Toe-Off. Also Bill´s propulsion arch states that we go from ER to IR and back to ER. So yeah...I´m confused. Pls send help.
@@ZacCupplesPT Sorry, I´m still struggling. What are you defining as initial toe-off? And are the graphs from Human Locomotion wrong or is maximum AR @Toe-off just not defined as rotation relative to the pelvis? The fact that we reach maximum IR @mid-stance is still not making too much sense to me...
@@mtmtgym Initial toe off - earliest phase of propulsion/late stance. Femur will still have some relative IR. As the big toe begins extending, thats when the calcaneus will re-invert, which is what drives ER/transition to swing. So hip is IR position, beginning to ER. Would be the same as if I extend my elbow from a flexed position. Does that clarify?
good one Zac, just wondering when the leg is in swing phase the knee is in flexion (kept straight) but are the toes in plantar flexion, along with the ankle, in addition to being supinated and inverted? also when the foot hits the ground with the heel does the ankle dorsiflex with the toes also dorsiflexing, and the knee bends forward so as to open up slightly into knee extension?
hi zac, i have a left rotated pelvis that wont turn back to neutrally facing straight forward and hence i have a terrible compensating walking gait when i walk sometimes i feel something click and my gait goes back to normal as if my pelvis was totally straight. then, the next day. or couple hours later i go back to terrible walking mechanics again. just wondering if you can do a video on why this happens. and maybe on how my brain can "maintain" this neuromuscular pattern of walking properly instead of going back to bad walking mechanics
You mentioned pri, the common compensation pattern and the other one was called the dunnington stress pattern? Not sure if I heard that correctly. By the way are you generally moving away from pri?
@@ZacCupplesPT At around 6:00 you are saying if someone is limited in extension,adduction,IR they might not need to work on early stance mechanics and then you are suggesting bottom up split squat with left leg in front , which is early stance biased .
@@ashwanidagar8660 You are right, it is early stance biased with the shift. It also is at about 90 degrees of hip flexion, which has slightly more internal rotation-bias based on line of pull of posterior rotators. It's basically like a 2-for-1 in that regard, at least what i've seen results-wise.
