What is the plane of the scapula?
The angle of the scapula in its resting position, normally 30° to 45° forward from the frontal plane toward the sagittal plane. Movement of the humerus in this plane is less restricted than in the frontal or sagittal planes because the capsule is not twisted.
What plane does scapular retraction occur in?
In the sagittal plane, around a latero-lateral axis the scapula rotates posteriorly (posterior tilting) or anteriorly (anterior tilting). External and internal rotation occurs around a cephalo-caudal (longitudinal) axis.
What plane does Scaption occur in?
Movement occurs in the scapular plane, about 30 degrees anterior to the frontal plane. The patient maintains the arm at shoulder height for 2 seconds and the slowly lowers it to the starting position. Resistance may be added as strength increases.
What is Scaption movement?
Scaption refers to the movement of raising your arms from your sides and slightly forward. Shoulder or scapular strength exercises can promote healthy movement patterns and improve posture and muscle function.
How does the scapula work?
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.
Why is scapular plane important?
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 does the scapula do during shoulder internal rotation?
Upward rotation of the scapula on the thorax is the primary motion of the scapula observed during active elevation of the arm and plays a significant role in increasing the range of elevation of the arm overhead. This motion places the glenoid fossa in a position to support and stabilize the head of the raised humerus.
Why is the scapular plane important?
What is the function of the scapular?
What is the main function of the scapula?
How do you stabilize the scapula?
Due to the multiple attachment sites, the primary role of the serratus anterior is to stabilize the scapula during elevation and to pull the scapula forward and around on the thoracic cage. Advancement of the scapula to an anterior position on the thoracic cage is termed protraction or scapular abduction.
What’s the best way to do scapular plane elevation?
1.Secure the band to the same foot as your throwing arm. 2.Stand with your arm at your side and “thumb down”. 3.Keeping your elbow straight, bring your arm up to shoulder height but at 45 degree angle between the front and the side.
What do the X’s on a levator scapulae mean?
Levator Scapulae (Wikipedia) The X’s represent the Trigger Points. There is no difference between the black and white X’s. The red shaded area is the referred pain caused by the Trigger Point and the darker red means more people experienced pain in that area.
What are the muscles responsible for scapular elevation?
(a) Muscles responsible for producing scapular elevation. Dashed red line = upper trapezius; solid purple lines = levator scapulae; solid white lines = rhomboids. (b) Muscles responsible for producing scapular depression.
What kind of muscles are involved in scapular protraction?
Based on the relative amount of activity in each of these muscles, other scapular movements (upward/downward rotation, internal/external rotation, and anterior/posterior tilt) may occur simultaneously with scapular protraction.
