This is not medical advice. The content is intended as educational content for health care professionals and students. If you are a patient, seek care of a health care professional. Correct scapular alignment is necessary for proper shoulder girdle function. The scapula plays an integral role in this construct. Many muscles attach onto it from different sides and dysfunction in any of those muscles can lead to a misalignment and possible shoulder pathology e.g. dyskinesia

I genuinely appreciate how you guys keep all of your content online to show how you progress with the evidence and how you are willing to challenge previous narratives. It shows true humility and modesty and it makes you guys all that much easier to stand behind! Thank you for making wonderful content so accessible to the general public
PERFECT. I study for my Pilates course and this is the best information. With all examples af ways of movements and all. Thanks a lot!!! I will follow with interest.
Incredible simple and clear explanation. Thank you!!
Thank you! It is very good! Learn a lot in this video!
You are amazing, thank you!
Scapular Alignment
Depression/elevation
- T1= Shoulder + acromial height
- T2= Superior angle
- T7= Inferior angle
(Depression= more horizontal alignment)
Abduction/adduction
- Medial border= 4 fingers from spine
Rotation:
- 30 degrees (or around thorax)
Movements of scapular:
- Downward/upward rotation
- Anterior/posterior tilting
- External/internal rotation
Muscles responsible for abnormal position:
Upward rotation:
Short/actions:
- Descending trapezius and inferior serratus
- Pectoral minor
Downward rotation:
Inferior angle more medial
Short/actions
- Levator scapular
- Rhomboid
Long/weak
- Descending trapezius
- Serratus Anterior
Posterior tilting:
- Ascending trapezius
Anterior Tilted Scapula:
Inferior angle tilting off the thorax
Short (muscles attaching to coracoid):
- Pectoralis minor
- Biceps Branchii (short head)
- Coracobranchialis
Adduction:
Short/action
- Transverse part of trapezius
- Superior trapezius
- Rhomboids
Long/weak:
- Serratus anterior
Abduction:
Distance between medial border and spine >7.5 cm. Glenoid anterior
Short/action
- Serratus anterior
- Pectoral major
Depression:
Action/short
- Pectoralis major
- Latissimus Dorsi
Weak
- Descending/superior Trapezius
Elevator:
Just ACJ elevation- (i.e) with rotation
Short
- Levator scapulae
Superior angle + ACJ elevation
Short
- Levator scapulae
- Descending trapezius
Entire scapular spine
Short
- Levator scapulae
- Descending trapezius
- Rhomboids
Winging Scapula:
Short/actions:
- Subscapularis
Long/weak:
- Serratus anterior
Other:
- Hyperkyphosis
- Scoliosis
This is the best for anatomy education thx for sharing
Sensacional! Muito obrigado!
Thx Bruno, appreciate it!
Thanks bro
Amazing! Thanks a ton
You’re welcome 😊
can u talk about scapular dislocation thank u
Thank you so much
Many thanks
Gracias por subtitular el video en español, saludos desde Chile, Santiago.
De nada, saludos desde Amsterdam
do some videos how to engage lower traps and serratus stabilizer for exercises to glide scapula around thorax and during pushup chin up military press etc how to engage them please
It seems like motor control exercises for the scapular most probably don't alter kinematics:
www.ncbi.nlm.nih.gov/pubmed/26847012. So we'd rather focus on general strengthening of the scapular muscles:

thank youuuu. este video es oroooo :) congrats for made this excelent video
Thanks a lot .
Ur welcome!
Thanks 👍👍
Ur welcome!
Thanks amazing
Thank you Moritz
Can I ask how to tell the difference between 4:32 Superior Angle+ACT elevated and 4:38 Entire Scapular spine elevated ? I really appreciate if someone can answer for me.
For those who've never heard of this before:
Upper Trapezuis - trapezius pars descendans
Middle Trapezius - trapezius pars transversa
Lower Trapezius - trapezius pars ascendens
Btw wonderful video, really helpful!
True, maybe that should have been clarified. We used the latin nomenclature.
4:04 Short Pec major or Pec minor ?
Thanks for the video, I have a right downward rotated scapula and i'm trying to reinforce my right upper trap. Why do you say that this could be caused by a short levator scapulae? Shouldn't be the opposite? A short levator shouldn't pull my scapula up?
If you look at the axis of rotation of the scapula you can see that it is a downward rotator of the scapula.
It does pull the scapula up though, that's correct and is another function of this muscle.
@@Physiotutors Hello ! It is ok to abuse levator muscles for downward rotation to get more range of motion etc ?
(With inferior angle dyskinesia in mind) would it be fair to reason that static dyskinesia is more likely due to hypertonicity while dynamic dyskinesia might be due to muscle weakness (especially in the eccentric phase)?
don't know what you mean with inferior angle dyskinesia but for example winging (static) can be apparent with a lesion of the long thoracic nerve which results in the complete opposite of hypertonicity. I could agree with your second statement that impaired strength could alter kinematics though we know that (despite maybe in overhead athletes) scapula dyskinesia is not evident in the general population
Do u have any videos of gait analysis???
Our Gait Analysis video is the second most viewed video on the Channel. Simply check the videos tab 👍🏼
weak lower traps can be the reason for dyskinesia ? and overactive upper trap
+ANKIT TIVREKAR yes as stated in the video
Sir PL make color musle pictures to understand it better.
Is scapular dyskinesia and sick scapula same terms?
My scapula inferior angle is not really angled outwards but inwards. Been searching for some self rehab but cant seem to find any.
Can be a normal variation. No need to worry about it as no research up to date shows that scapular dyskinesis is linked to the development of shoulder pain except in elite rugby and elite handball players.
hi. what about when the medial border of the scapula is prominant? scapula will rotate in the vertical plane. so will the scapula will be abducted or adducted ? nd which muscles will appear to be weak or tight ?
Hi Mahila, what do you mean by vertical plane? With a prominent medial border there is often weakness of the serratus anterior.
@@Physiotutors thanks alot. I checked ur other videos and made my self clear. :)
is there any excercise to reset scapula position abd shape thank u
Think the video gives certain example of why a scapula might be "discplaced" in the first place.
Strengthen the weaker muscles and stretch the short/stiff muscles. There is no single exercise.
It depends. There are X amount of exercises for what you said. You have to be very specific along with knowing what to do with those exercises and performing them without any compensations.
hey, in minute 3 you was saying/showing, that the Serratus is also adducting the Scapula? This is really true? I dont find any literature witch says this.
Might be referring to serratus posterior superior, in case you were thinking of serratus anterior that is!
@@sydisemma yes of course i was thinking the serratus anterior. They only talking about the Anterior and even the Serratus Posterior have not really direct impact on the shoulderblade (in my knowledge).
My scapula misalignment has caused TOS
Shoutout idubbbz content cop theme haha
informative video but couldnt follow it completely due to the poor understanding of the terminologies and scapular tipping movement
+Sweety Rajan Thanks! If you can let us know what was unclear, we can maybe clarify it here in the comments. Any concrete questions about the terminology and scapular tipping?
Physiotutors I would like to know the scapular movements especially the anterior and posterior tipping and rotations with the muscle work..
But that's explained in the video. We mention which muscles are primarily concerned with the motions you describe or are we missing something?
Physiotutors I mean the biomecanics of movement with the muscles and insted of ascending desecending ..upper and lower fibers will give more clariry
I think the initial musical theme is a bit too loud comparet to the level of the voice
Hello! I am Lars... lets play de' game where we learn eachothaz namez!
