Upward rotation is accomplished by the trapezius and serratus anterior muscles. Downward rotation is accomplished by the force of gravity as well as the latissimus dorsi, levator scapulae, rhomboids, and the pectoralis major and minor muscles.

What muscle raises and rotates scapula?
The levator scapulae functions to elevate the scapula and tilt the glenoid cavity inferiorly by rotating the scapula downward.
What happens during upward rotation of the scapula?
The scapula upwardly rotates when you reach your arm up overhead. During this motion, the inferior angle of the scapula (see photo above) rotates up (superiorly) and to the side (laterally). At the top of your overhead motion, your scapula should be upwardly rotated about 55 degrees.
What muscles elevate the scapula?
The trapezius is a large flat muscle that covers much of the upper back. Its fibers extend in several directions, and it elevates, retracts, and rotates the scapula freely. The rhomboideus and the levator scapulae muscles also retract and elevate the scapula.
What is the upward movement of the scapula?
Then when we look at lateral rotation or upward rotation. It's like this opening up or raising the glenohumeral joint. And medial rotation bringing it back down.
What muscle is responsible for retracting the scapula?
Retraction of the scapula is sometimes called adduction of the scapula. The scapula is moved posteriorly and medially along the chest wall. Muscles: rhomboideus major, minor, and trapezius are the prime movers.
How does the scapula rotate?
The movement of the scapula can be described by rotations in relation to the thorax. The scapula moves around a dorso-ventral axis, resulting in a rotation in the frontal plane. In this movement the glenoid cavity is turned cranially (upward rotation) or caudally (downward rotation).
What is upward and downward rotation of scapula?
Quote from video:
For upward rotation the patient's arm is brought into flexion or abduction. With one hand while the other hand grabs onto the medial border and the inferior angle of the scapula.
How do you increase scapular upward rotation?
Exercises that have been shown to increase the activation of the Upper Trapezius and effectively help us fix our upward scapular rotation are the following:
- Overhead shrugs.
- Monkey Shrugs.
What causes anterior tilt of scapula?
The muscles that contribute to anterior scapular tilt are the: Pectoralis minor. Levator scapulae. Rhomboid (vaguely)
What causes posterior tilt of scapula?
Scapular adduction and depression are produced by the LT, as well as other scapular muscles (e.g., MT, rhomboid, levator scapulae, and latissimus dorsi) , whereas scapular posterior tilt is primarily caused by the LT and serratus anterior [1,22,23].
What does posterior tilt of scapula mean?
This is a good thing and called posterior tilting of the scapula. We need to get the shoulder blade into this position in order to achieve a full overhead position. This posterior tilt of the shoulder blade is primarily allowed by our upper back’s ability to extend or flatten out.
Why is my shoulder rotated forward?
The forward shoulder posture is a common posture created by an imbalance of the muscles that upwardly rotate and posterior tilt and the muscles that downwardly rotate and anterior tilt the scapula.
How do you fix shoulder forward rotation?
Stand tall, open your chest and move your hands back and towards the ceiling. Stop when you feel a stretch in the shoulders and biceps muscles. Hold in this position for 20–30 seconds. Release the stretch and return hands to the starting position.
How do you fix a rotating shoulder forward?
Quote from video:
So that through the combination of releasing the tight muscles pulling your shoulders forward and strengthening the muscles that pull your shoulders backwards. You're not going to have to think about
What does scapular winging indicate?
Scapular winging is almost always caused by damage to one of three nerves that control muscles in your arms, back, and neck: the long thoracic nerve, which controls the serratus anterior muscle. the dorsal scapular nerve, which controls the rhomboid muscles. the spinal accessory nerve, which controls the trapezius …
What nerve causes winged scapula?
The most common etiology of a winged scapula is usually due to damage or impaired innervation to the serratus anterior muscle. The nerve that innervates this muscle is the long thoracic nerve. Sometimes, this nerve can be damaged or impinged, leading to malfunction of the serratus anterior muscle.
What muscle prevents scapular winging?
Serratus Anterior Palsy
In the supine position, the weight of the body prevents winging by compressing the scapula against the thorax and allows for full shoulder range of motion.
What is serratus anterior palsy?
Introduction. Isolated serratus anterior (SA) paralysis is a rare condition that is secondary to direct trauma or overuse. Patients complain of neuropathic pain and/or muscle pain secondary to overexertion of the other shoulder stabilizing muscles.
What is trapezius palsy?
Trapezius palsy is an uncommon nerve condition in the shoulder that causes pain and weakness. It involves injury to the spinal accessory nerve at the neck or shoul- der. The spinal accessory nerve runs from the neck to the trapezius muscle.
What is scapular dyskinesis?
Scapular dyskinesis (which may also be referred to as SICK scapula syndrome) is an alteration or deviation in the normal resting or active position of the scapula during shoulder movement. For most people, the scapula moves in abnormal ways due to the repetitive use of the shoulder.
What is Suprascapular nerve palsy?
What is suprascapular nerve palsy? Suprascapular nerve palsy occurs when the suprascapula nerve is damaged. This can cause pain and weakness in the muscles that the suprascapula nerve innervates (controls). The suprascapula nerve innervates the supraspinatus and infraspinatus which are both muscles of the shoulder.
What are symptoms of suprascapular nerve impingement?
The signs and symptoms of suprascapular neuropathy include:
- Shoulder/arm weakness or heaviness.
- Radiating/burning pain to the neck, back or arm.
- Pain that worsens with shoulder movement.
- Loss of shoulder function.
- Discomfort in shoulder and upper back.
- Atrophy, wasting or shrinkage of upper shoulder muscles.
How do you test for suprascapular nerve entrapment?
Magnetic resonance imaging (MRI) scans can assess soft tissue causes of entrapment as well as associated pathology. Clinical suspicion from the history and physical examination should help establish a diagnosis of suprascapular neuropathy, and nerve conduction studies are used to confirm the diagnosis.
