One of the new exercises she has me doing is the Romanian deadlift (straight leg deadlift). This is an exercise I was also told to do by my previous physiotherapist but my current physiotherapist said I wasnt ready for it until now since ive improved my posture. Focus on hip hinging and sitting back with your glutes, My lumbar spine is pretty straight when doing it. There is no “butt wink” (lumbar spine flexion), which is good form. I feel my glutes and hamstrings working. The hamstrings also get a good functional stretch. She said Im more ready to perform the movement than I was before because my posture has improved. My anterior pelvic tilt is minimal now, so proper muscle recruitment is occuring. The exercise also helps reinforce the good posture I have gotten from rolfing and helps reinforce good motor patterning during daily movements. I feel like im engaging my glutes and hamstrings more especially when I bend over.I perform the bend similarly to how I would perform the romanian deadlift and feel my glutes and hamstrings working. I have only done the exercises twice tho since beginning physio with my new physiotherapist. 

One concern I had with performing the excersise is the assymetry in my pelvic alignment. Left side being different than the right. As I perform the movement there is assymetry from left and right side because of the misaligned pelvis. The physiotherapist said my pelvic assymetry is much improved since the rolfing and the previous physio exercises and that any differences between the 2 sides is subtle. She still recommends performing the romanian deadlift. 

Perhaps you should try taking a similar approach by correcting overall posture first. Then performing physio exercises to facilitate permanent change in the new posture and good motor patterns and proper functional movements. The new posture will allow you to perform the exercises properly. The exercises will re-wire your muscles and brain to proper muscle balance and movement. 

Thanks for the video.Very interesting. So according to the video a lack of transverse plane movement causes excessive frontal plane (swaying of the hips from side to side) and excessive sagittal plane movement (lordosis and kyphosis, anterior pelvic tilt) leading to IT band tightness and then knee pain. He brings up the point of doing SMR on IT band (without causing pain and discomforrt because this would trigger your kinetic chain to tense up and you wouldnt get effective release but also suggests that foam roller isnt enough) to help resolve the issue which I have been doing, and so far it hasnt resolved my issue. I have been rolling with foam rolling lately perhaps i switch to PVC pipe and lacrosse ball again.

Would exercise that activate and strengthen transverse plan movements address the cause? He makes it sound like that in the video.

There called pelvic clocks. Here is a good video:

Since glute strengthening has only helped somewhat previous physiotherapist thinks weak, inactive deep core muscles is leading to poor stabilization of the lumbo-pelvic-femoral complex and leading to poor motor control and inappropriate movement of legs during functional activity leading to associated IT band tightness and knee pain

1) Diaphragmatic breathing – deep breathing using diaphragm rather than chest. Breath in as stomach expands. Breath out as stomach gets drawn back in.

2) Pelvic Floor activation – activate pelvic floor during deep breathing by imagining as if you are holding in your piss or lifting your testicles up. Should be completed when breathing out (stomach getting drawn in). When breathing in (stomach expanding) eccentrically activate pelvic floor by imagining as if you are pissing and forcing a piss out.

3) Transverse abdominis (TVA) activation – when breathing out (stomach getting drawn in) imagine drawing in your navel and belly button closer to your spine.

Note: When breathing in activate diaphragm. When breathing out activate pelvic floor and TVA.

Release the deep gluteal muscles on the right side that might be causing my right femur to be more externally rotated relative the left. My right thigh muscle is normally more externally rotated during rest and functional activity when compared to left. This is a noticeable asymmetry that my new physiotherapist thinks might be leading to the tight IT band and knee pain. GUNS IMS will be completed to relax my deep gluteal muscles (piriformis, gemellus, obturator internus, quadratus femoris). Also, advised to perform stretches and smash this area with lacrosse ball.

Physiotherapist brought up rolfing as a possibility to re-establish body alignment. She said we need to get the body algined properly prior to physiotherapy exercises because without the proper alignment any exercises we do will reinforce the misalignment. She wants me to discontinue any exercises prescribed by my previous physiotherapist and focus re-aligning the body first. She said we will slowly start adding exercises in as the body becomes properly aligned
