The shoulder joint has the greatest range of motion of any other joint in the body. Shoulder Horizontal The pectoralis major (from Latin pectus 'breast') is a thick, fan-shaped or triangular convergent muscle, situated at the chest of the human body.It makes up the bulk of the chest muscles and lies under the breast.Beneath the pectoralis major is the pectoralis minor, a thin, triangular muscle.The pectoralis major's primary functions are flexion, adduction, and internal rotation of the humerus. The latissimus dorsi muscle at the level of the shoulder, it is the most important internal rotator, as it is the most important for the adduction and flexion of the shoulder. External rotation Acromioclavicular 1. Shoulder horizontal abduction stretching effectively ...

With strong horizontal abduction and outward rotation of the humerus, you can generally find these muscles in relation to a triangle formed by the inferior line of the posterior deltoid, the lateral border of the trapezius, and a line formed by the superior aspects of the teres major and latissimus dorsi.

The latissimus dorsi has several different functions, all of which involve movements of the arm. The last two muscles, the teres major and coracobrachialis, cross the shoulder joint, but do not reinforce it. Flexes and adducts the shoulder joint. Background: Stretching maneuvers for the pectoralis minor muscle, which involve shoulder horizontal abduction or scapular retraction, are performed in clinical and sports settings because the tightness of this muscle may contribute to scapular dyskinesis. If you hug yourself, your shoulders are adducting. Shoulder Horizontal Abduction is a great exercise to increase strength in the Deltoids, Infraspinatus and Teres Minor. In addition, re- cent studies have reported differ- ences between muscle groups in the developmental patterns of absolute The muscles involved would include: teres minor, infraspinatus, and deltoid (posterior fibers). Horizontal Abduction Test and Air. Shoulder Horizontal Abduction axis. Due to the uniqueness of the joint design, a healthy individual should be able to freely move their shoulder in eleven planes — flexion, extension, neutral and horizontal abduction, neutral and horizontal adduction, neutral and horizontal internal rotation, neutral and … With the head of the humerus bone sitting in the shallow pocket of the shoulder blade, the shoulder is termed a ball-and-socket joint.

The supraspinatus muscle initiates the abduction movement of the arm by pulling the humeral head medially towards the glenoid cavity thereby creating a fulcrum for movement. The deltoid controls abduction from 15 to 90 degrees. Shoulder joint abduction, flexion (anterior fibers), extension (posterior fibers), and (depending on patient position) internal (patient supine) and external rotation (patient prone).

Glenohumeral joint (Articulatio glenohumeralis) The glenohumeral, or shoulder, joint is a synovial joint that attaches the upper limb to the axial skeleton. Like its antagonistic motion, horizontal abduction, horizontal ADDuction is a motion that occurs in the gravity-eliminated plane if performed in the anatomical position. Receiver operating characteristic curve for the shoulder horizontal abduction range, as a risk factor for developing tendinopathy in the shoulder pain. Adduction: downward movement of the humerus in the frontal plane (sagittal axis) returns the body from abduction. Lower Trapezius. It probably occurred more commonly on its own in the 60s and 70s as it is the movement made when entering a room, spreading beads hung in a doorway (as in entering the room saying, "Hey, groovy pad, man"). Abduction of scapula 3. Trapezius Horizontal extension of the shoulder refers to the ability of the shoulder to move the arm across the body and back with the arm parallel to the ground. The prone horizontal abduction in external rotation/full can (prone T) exercise is part of a series of exercises known as the T-Y-I-W series and is intended to improve scapulothoracic joint and glenohumeral joint muscle function and shoulder girdle stability. 1.) Which muscle is the strongest medial rotator of the arm? 9. Shoulder horizontal abduction Testing position [edit | edit source] Patient is supine to one side of the plinth with arm unsupported if possible Shoulder is abducted to 90 degrees and elbow is flexed to 90 degrees Goniometer Placement [edit | edit source] The opposite, or antagonistic, action of bringing your arm toward the side of your body is called adduction. posterior deltoid. The ideal amount of horizontal abduction is that which leads to the highest velocity of horizontal adduction and allows the glenohumeral joint to remain stable and healthy over the long term. Shoulder horizontal abduction: Drive thorax rotation while keeping the head forward, or drive active humeral external rotation. … If you were doing a backhand swing with your racket in tennis, you would be doing horizontal extension (also called horizontal abduction) and lateral rotation at the shoulder joint. It is important to practice specific exercises for horizontal extension. The infraspinatus is located on the posterior side of the body, inferior to the spine of the scapula. The effectiveness of stretching maneuvers for the pectoralis minor muscle is unclear in vivo. Each band has different resistance. This means when it is time for manual muscle testing, you will have to reposition the person to test for Fair strength and above. Several muscles can abduct the shoulder. Banded 90/90 Internal Rotation. These studies often observe the scapula during repeated movements (at least 3) and at a rate of 45 degrees per a second i.e it will take four seconds to get to the top of elevation and 4 seconds to come down. This action at the shoulder can occur when your arm is in different positions (flexion, abduction, etc.). An inability to horizontally abduct the arm beyond 30 degrees indicates a right brachial chain that needs inhibition. The deltoid (posterior).
