The lifter stands erect, hands about shoulder width apart, and slowly raises the shoulders as high as possible, and then slowly lowers them, while not bending the elbows, or moving the body at all. [2] The lifter may not have as large a range of motion as in a normal shrug done for active flexibility. It is usually considered good form if the ...
The glenohumeral joint has been analogously described as a golf ball (head of the humerus) sitting on a golf tee (glenoid fossa). [5] The rotator cuff compresses the glenohumeral joint during abduction of the arm, an action known as concavity compression, in order to allow the large deltoid muscle to further elevate the arm. In other words ...
The shoulder joint is a ball-and-socket joint between the scapula and the humerus. The socket of the glenoid fossa of the scapula is itself quite shallow, but it is made deeper by the addition of the glenoid labrum. The glenoid labrum is a ring of cartilaginous fibre attached to the circumference of the cavity.
The shoulder girdle is a complex of 5 joints that can be divided into two groups. 3 of these joints are true anatomical joints, while 2 are physiological ("false") joints. [explain 1] Within each group, the joints are mechanically linked so that both groups simultaneously contribute to the different movements of the shoulder to variable degrees.
One possible long-term consequence result of a rotator cuff tear is called proximal humeral head migration, this is where the "ball" of the shoulder joint rests higher in the shoulder joint "socket" disrupting normal shoulder mechanics. [89] Only tear size is an independent predictor of humeral migration.
Palpation of sternoclavicular joint, clavicle, acromioclavicular joint, subacromial bursa, bicipital tendon. Evaluation of passive and active range of motion: Neck range of motion should be assessed that may reveal a neck source of shoulder pain. The Apley scratch test specifically tests range of motion and in a normal exam, an individual ...
Front raise. The front raise exercise is used in weight training. It primarily works the anterior deltoid and the clavicular head of the pectoralis major through the use of arm abduction and flexion through the frontal plane. [1] The training volume, or number of sets and repetitions performed, depends on the lifter's training program and goals.
Rear delt raise. The rear delt raise, also known as the rear deltoid raise, or rear shoulder raise is an exercise in weight training. This exercise is an isolation exercise that heavily works the posterior deltoid muscle. The movement is primarily limited to the two shoulder joints: the glenohumeral joint and the scapulothoracic joint.
