What is scapular plane position?

What is scapular plane position?

The normal resting position of scapular as it lies on the posterior rib cage is at an angle of 30 to 45 degrees. Raising the arm 30 to 45 degrees from the coronal plane is called the scapular plane.

What is the ratio of the shoulder joint in relation to the scapula?

Scapulohumeral rhythm is the rhythm in which our scapula moves, in relation with the humerus in the glenohumeral joint as a means for shoulder mobility. The standard ratio is often recognized as 2:1. This means for every 2 degrees the humerus moves, the scapula moves 1 degree.

What plane of motion is scapular Elevation?

Four movements of the scapula occur in the frontal plane: elevation – associated with reaching when glenohumeral abduction and flexion are limited in range. depression – associated as a closed-chain motion with crutch walking, transfers, and use of a walker.

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.

Why do exercises in scapular plane?

Sometimes it’s referred to as scapular plane elevation. During scaption, you draw your shoulder blades toward the center of your spine, which helps to open your chest. The movement builds strength in the shoulders and back. Paying attention to your form during scaption can help develop body awareness.

What is shoulder flexion?

A shoulder flexion is when you move your arms anywhere from a resting position by your sides to straight above your head. An extension is when you move your arms and stick them out behind you. The muscles involved in the flexion movement include the anterior deltoid, pectoralis major and coracobrachialis.

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.

When performing 30 90 degrees of humeral abduction what is the Scapulohumeral ratio?

Scapulohumeral rhythm ratios between 30o and 90o ranged from 1.64:1 to 3.76:1; but none were equal to the clinically accepted 2:1 ratio. We then observed a decline in scapulohumeral rhythm (0.90:1) as subjects elevated their shoulders from 90o to 120o of elevation.

What plane does elevation occur in?

Elevation refers to lifting, and depression refers to lowering. These movements only occur in several regions of the body and are a result of movement along the coronal plane.

How is the scapula related to shoulder function?

Normal Scapular Function. The scapula is anatomically and bio- mechanically intimately involved with shoulder function. During the process of shoulder and arm move- ment to achieve a change in gleno- humeral position as well as during motions required for athletic and daily activities, the two are linked.

What are the different types of scapula movements?

Scapular Abduction – also called scapular flexion or protraction. A movement where the scapula moves laterally away from the spinal column. 4. Scapular Adduction – also called scapular extension or retraction.

Is there bony articulation between scapula and thorax?

No actual bony articulation exists between the scapula and thorax, which allows tremendous mobility in many directions including protraction, retraction, elevation, depression, anterior/posterior tilt, and internal/external and upward/downward rotation. When describing scapular positions, the point of reference is the glenoid.

What are the effects of weakness in the scapular stabilizers?

Weakness of the scapular stabilizers and resultant altered biomechanics could result in: 1) abnormal stresses to the anterior capsular structures of the shoulder, 2) increased possibility of rotator cuff compression, and 3) decreased shoulder complex neuromuscular performance.
