The infraspinatus and its role in subacromial impingement: Mechanism and treatment
Вставка

- A seemingly common but, at least to the best of my knowledge, unknown musculoskeletal injury mechanism, is infraspinatus impingement at the subacromial passage. The superior portion of the infraspinatus passes partially under acromial roof (the acromial bone), and in internal rotation of the humerus, an even greater amount of the infraspinatus tendon will be exposed to potential impingement at this passage during excessive scapular downwards rotation during elevation of the arms.
The most vulnerable part of the infraspinatus is the superior portion due to aforementioned reasons. Unfortunately, it is also the most difficult part of the infraspinatus to target with rehabilitative exercises, and it is especially important to understand that standard external rotations will not tend to effectively target these tissues. The reason for this, is that its superior attachment on the humeral head makes it an angled abductor to a greater degree than an external rotator. I have some preliminary suggestions for treatment in this video. Some refinements may be posted at a later time.
thank you for alle the videos, all the knowledge. People please give this men a thumbs up!
I would love to see a video on the role of the neck, spine, and head on visual snow.
Was happy to see a see a new MSK neurology video. Excellent detailed explanation and demonstration as always Kjetil. Thank you for sharing your knowledge and expertise with us.
Btw you are looking extremely healthy and fit!
My favourite UA-cam channel finally posted again!!
The legend! Thank you, regards from Split
Much gratitude for this ❤❤❤❤❤
Thank you for alle vídeos
Informative video! If I were to make a video suggestion - a video on proper mechanics of the standard squat would be epic, and perhaps how mechanics/cues might change whether it is high/low bar, front, etc.
Thank you
Thank you 🔥
Big man just did a video with Bryan Johnson, well done lad!
Any videos on cervical stenosis? C4 to c7. It feels like tos or impingement. 5 years of this pain. My shoulder is forward a bit
I discovered a similar excercise with a cable helps, thanks for the tip about not doing it to failure
also noticed that doing lateral raises makes it worse, or is that ''good'' pain, not sure
I did a consultation with you for TMD. Fast forward half a year I now have this exact thing😅
Thanks for the video!
did he advise you to keep your mouth shut when sleeping?
@@reet-ard1527 no, to get a mandibular advancement splint
Just today what I thought was my supraspinatus started acting up, pain at the tip of what seemed to be my trap, I figured it was my supraspinatus, started using a lacrosse ball near the insertion point of the infraspinatus and felt quite tender in that area, did some self tissue massage with the ball and after the pain was gone and I was able to continue my workout pain free
hi! can you please do a video about knots between shoulder blades.it's been buggin me for years, and your videos about posture has helped alot
Dorsal scapular nerve
i've had a weird lingering feeling, sort of like a constant pressure around the infraspinatus area for almost 5 years now. Seems to disappear if i raise my elbow above 90 degrees, also disappears when lying down/sleeping. No pain when lifting or doing any movements/exercises (and heavy too). Not sure if it's an impingement or what.
I want to say MSK neurology is the real deal, from constant pain in my right shoulder, non stop clicking and popping, bad nerve pain all over my right torso, neck and shoulder, felt like I was carrying dead weight on my right arm. I am not 100% now but I am now achieving skills I had given up on, pike push-ups, back bridges, my traps feel strong but most importantly they feel awake and controlled. Can’t forget to train the rotator cuff, I didn’t even know what that was before I Skyped msk
I have similar symptoms. Was the rotator work what helped? Or was there more to your rehab?
@@thepurelegend its alot more than the rotator cuff man, but its an important piece to the puzzle, personally i first had to be constantly aware of my posture, spending too much time on my phone was making me develop a cervical hinge that msk neurology has a video on. Lots of foam rolling to open up the thoracic spine and pulling my neck up tall and long. Retraining the scapula to move better especially in upwards rotation and posterior tilt, this took a lot of work since i had nerve pain all over my scapula region and neck due to bad scapular posture that gave me TOS. Lastly i trained my rotator cuff like crazy but i actually had internal impingement which was causing me alot of pain and tightness in my posterior shoulder, so instead of training the external rotators i had to train my subscapularis so i had to do alot more of internal rotation than external rotation, in my experience internal rotation also helped my scapula stick to my ribcage better.
Progress has been slow for me. When I started self treatment I couldnt lift my shoulders up even for a second. Some days its still very hard but some days its almost easy to do. Im not sure what causes such drastic swings but I do notice a ton of tension in this area. It is very hard to troubleshoot because any massage or trying to work the tissue quickly becomes overwhelming.
High stress or making mistakes
Is it good to train this muscle even if you do not have any issues?@@MSKNeurology
What specific brand of exercise band did you use?
No specific brand
Is it good to train the superior head even if you are not hurt? @@MSKNeurology
Dr.Larsen, Did you see the video Dr.Centeno made about you? He was trying to discredit your work
Couldn't care less about them
@@MSKNeurology With the superior head of infraspinatus should it be trained if it is not hurting? Also how can I help flat feet? I am responding to this comment because it is recent.
