What is a scapular plane?
Raising the arm 30 to 45 degrees from the coronal plane is called the scapular plane. Since the rotator cuff muscles originate off the scapular, the position of the humerus in the scapular plane increases the length-tension of the deltoid and cuff muscles, helping to facilitate optimal muscle force.
What happens to the scapula during shoulder flexion?
When we perform flexion, the glenohumeral (GH) joint contributes 100°-120°. The scapula on the thorax contributes to elevation (flexion and abduction) of the humerus by upwardly rotating the glenoid fossa 50° to 60° from its resting position.
What is scapular plane position?
Continue all exercises listed above • Begin sub-maximal pain-free deltoid isometrics in the scapular plane (avoid shoulder extension when isolating posterior deltoid) • The scapular plane is defined as the shoulder positioned in 30 degrees of abduction and forward flexion with neutral rotation.
What is scapular plane abduction?
Background: Abduction is a movement commonly used in the assessment of shoulder dysfunction and prescription of exercises to improve shoulder function. Conclusions: Abduction can be performed within a 30° arc of the scapular plane with no change in shoulder muscle activation patterns.
What causes a winged scapula?
Most lesions associated with winged scapula are the result of blunt trauma due to repetitive movements, as seen in athletics. The most common cause of scapular winging is paralysis of the serratus anterior muscle due to the injury of the long thoracic nerve.
Why is scapular plane important?
It was a contraction of Scapular Plane Elevation. The shoulder blade is an extremely important part of shoulder rehab. In normal movement it rotates and elevates to change the position of the shoulder joint, providing a combination of strength and stability.
What are the scapular movements?
The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.
How serious is a winged scapula?
Scapular winging is a rare, but potentially debilitating condition that can affect the ability to lift, pull, and push heavy objects, as well as to perform daily activities of living, such as brushing one’s hair and teeth and carrying grocery bags [1].
What does shoulder flexion tell us?
Flexion of the shoulder is an anatomical term of motion that refers to the rotation of the shoulder so that the arm is moved forward or up. During flexion, the bones of the arm remain straight, and motion takes place at the shoulder joint. This movement is sometimes called forward flexion of the shoulder or just shoulder flexion.
What is the normal shoulder flexion?
A normal range of motion for shoulder flexion is 180 degrees. This involves moving your arms from palms against the side of your body to the highest point you can raise your arms over your head.
Is the scapula and shoulder the same?
As nouns the difference between shoulder and scapula is that shoulder is (lb) the part of an animal’s body between the base of the neck and forearm socket while scapula is (anatomy) either of the two large, flat, bones forming the back of the shoulder. is to push (a person or thing) using one’s shoulder.
What is shoulder forward flexion?
Flexion is also referred to as forward flexion. In the case of the shoulder, forward flexion is the motion of the shoulder when lifting the arm in front of the body, such as to point at something in front of you.
