Hi, thank you for the great execises. I wanted to ask about one thing, I am a Mckenzie practicioner and the directional preference for shoulder is mostly extension and internal rotation (around 70 percent) for shoulder derangements. Many painful conditions in the shoulder would fall into this derangment category. Shoulder abduction and wall slides can be considered flexion exercises. That means opposite direction against directional preference (which acording to MDT should be avoided). Can you somehow comment/reconcile on this issue ?
It's simple really. The rotatorcuff musculature is a group of local stabilizers with the main purpose to stabilize the shoulder joint in every movement. It's not the rotatorcuffs responsibility to make the movements, that is the job of the global movers like the latissimus or pectoralis major. So if you make a closed chain exercise, like the push-up, then you are greatly activating the rotatorcuff to stabilize the shoulder joint so that the pectoralis major can do the movement safely.
your videos are great! So much value and things to learn + you give us the research papers! I would only suggest working a little on the audio production so that there aren't so many changes in the volume from speaking to music. Love all you are doing!
Great video guys! I really like your relation to ADLs. But would you even start with lateral raises in early stage? Most times the patients aren't really able to do these without a lot of pain. Or would you say, as long as the pain, isnt there anymore in the next morning they are good to go?
We basically always use lateral raises. Even half a kg and having patients move up to the range where they have pain is fine. You can also do them in side lying and start at 90 degrees and have patients move up and down within a tolerable range. If it's still too much, go with isometrica
Fantastic. This is another example of theory vs reality. While we might expect forsake cuff muscles to activate best via isolated movements, the body doesn't totally behave that way
I see something in a paper which they sated that doing excersise with same velocity through all the reps can improve joint stability. Can we do these exercises same velocity and low weight which work by proprioception to increase shoulder stability?
Problem is EMG does not correlate with hypertrophy nor strength. Vigotzky papers talks about this in detail pretty well. We should probably ditch emg to predict hypertrophy or strength
This is interesting stuff. I found the 2022 paper on hypertrophy I will look into. My first thought is: ofcourse EMG does not correlate with hypertrophy as muscle activation is only one part of the puzzel for hyperthrophy. You also need enough training volume, nutrients, sleep etc. I can't find the study on strength though, please share.
The selection made is not solely made based on EMG results. Matter of fact is that a lateral raise or similar activate the RC to a similar degree as ERO exercises but are more likely to transfer into a patients ADLs And who doesn’t like to do push-ups ?!
