cause of impingement syndrome - scapulao humeral rhythm

It probably accounts for the largest portion of the shoulder impingement syndrome disease would be.

Impingement Syndrome is a disease that caused the pain supraspinatus confrontation clause of the humerus and the acromion of the scapula passing between its parts dithyeo cases jjiphi said.

This occurs mainly limited to the operation and raising arms above your head and follow the severe pain.

So What mueot cause this disease ??

In order to understand the cause, you must know the scapular humeral rhythm.

 

 

 

 

180degree humerus during arm elevation, not even moving the scapula and humerus should have to move, as by certain rules.
The scapular humerus is rotated 60 degrees above 120 degrees abduction, creating a 180-degree movement.

 

 

If you are causing a lack of upward rotation of the humerus can only be rotated 40 degrees if the upper level of the humerus should be approximately 140 degrees abduction occurs, it creates a narrowed the subacromial space impingement occurs.

 

 

 

The shoulder blades should be rotated 60 degrees upward and hagak of The scapula will reach the centerline side of the chest.
In the figure above hagak this does not look a long time in the chest centerline and do not meet the 60 degrees angle as shown in Figure B is rotated upward.
The probability of impingement syndrome occurs if you have these movements can be very high.
 
So then provide an explanation upward rotation of the scapula muscles that make ??

 

 

 

 

Upward rotation of the scapula is upper trapezius (UT), the lower trapezius (LT), jeongeogeun (SA) is carried out by the cooperative action of three muscles.
We have a lot of weight if you give goego sits on the chin or elbows in everyday life sitting relaxed on the shoulders This creates a weak jeongeogeun.
Jeongeogeun is weak, and change the activity of the upper trapezius excessively to compensate for this movement will scapula when the arm is swept upward climb occur.
This is also a cause of chronic shoulder aggregation.
 
Haebomyeon Summary
- The cause of the crash syndrome birotdoem in the upper rotation of the scapula inadequate
- weakness being activated by the upper trapezius and the SA
- impingement syndrome
 
It could be summarized thus
 
If the conclusions are reported to better evaluate the functionality of the jeongeogeun yakjeung if to give regain the upward rotation of the scapula function is normalized will no longer crashes occur ^^
 
Muscle strengthening methods of inspection and jeongeogeun I will post later.
