Glenohumeral joint

The Glenohumeral Joint and its Function Within the Human Body The glenohumeral joint, or shoulder joint, is one of the human body’s appendicular joints and boasts the greatest ROM (range of motion) of any joint in the body. An appendicular joint is a joint that is part of the appendicular skeleton which includes the pectoral girdle, pelvic girdle, and limb bones. The appendicular joints typically have a larger range of motion, but due to this are often weaker than those found in the axial skeleton

The glenohumeral (shoulder) joint involves three bones: the scapula (shoulder blade), the clavicle (collar bone) and the humerus (upper arm bone). The humeral head rests in a shallow socket on the scapula called the glenoid. The humeral head is much larger than the glenoid, so a soft fibrous tissue called the labrum surrounds the glenoid to help deepen and stabilize the joint. The labrum deepens the glenoid by up to 50% so that the head of the humerus fits better.1 It also serves as an attachment

The glenohumeral joint has the most instability but most range of motion when compared to any other joint in the body. It requires the labrum, ligaments and capsule to maintain stability and function. A glenoid labrum tear disrupts this joint leading to pain and instability (Fitzcharles). Tears in the labrum are common in athletes who use repetitive motions of the shoulder, such as football quarterbacks, baseball pitchers and weightlifters. These tears can sometimes be mistaken as glenohumeral join

created automatically for each phase of the protocols based on the classification rules (Fig. 35d). For example, class CandExe2FlexGlenoJ represents the candidate exercises for phase 2 of the protocol for patients with limited flexion of the glenohumeral joint. Each of the Mov* classes in the definition refer to the movements that the exercise must have to be classified in CandExe2FlexGlenoJ.

Type II SLAP LESIONS Alia Scriven Coppin State University KNES 427- Therapeutic Athletic Exercise September 30, 2016 Introduction Russell Carrington is a 25 year old right handed relief pitcher for the MLB team the Baltimore Orioles. Carrington has been playing baseball since he was seven years old and this was his third season in the Major Leagues. Carrington was at the mound and in the motion of throwing a fastball, when he felt a “pop” in his overhand motion. He dropped to his knees and clinched

Evaluation The clinical evaluation of labrum pathology can be difficult to diagnose due to each type of SLAP lesion having different mechanisms of injury, pain, and area that is affected. Type 1 SLAP lesions can usually be associated with rotator cuff pathology with a partial thickness tear of the supraspinatus ligament due to micro-tears. ^1,5 This is quite common in baseball players and other overhead athletes. Type II lesions can vary based on age; younger patients have more instability than older

Cardiovascular Endurance I did the 1 mile walk and my time was 17 minutes and 26 seconds. My heart rate at the end of my walk was 100 bpm. My VO2 max was a 48.72 and for my people are around my age that just ranked in the category of just good. I was not able to perform the 3 minute step test because of medical reasons. The benefits of the step test would be that there is not a lot of energy being exerted by the participants. Unlike running, stepping comes natural making this test less challenging

movement with the antagonists being the triceps, latissimiss dorsi and the trapezius. This movement involves the use of the third class lever, with the load being the racquet, and effort being the triceps and the fulcrum being the elbow, which is a hinge joint. Also at this stage, the non-racquet arm is fully extended pointing at the shuttle using the trapezius and the interior deltoid to extend the

Introduction The most commonly dislocated diarthrodial joint in the human body is the glenohumeral joint in the shoulder (Cutts et al., 2009). Shoulder dislocations are most prevalent in contact and collision sports; such as football, rugby, soccer, and wrestling where the shoulder receives a brute external force from another player or object (Mora et al., 2017). Furthermore, shoulder dislocations highly dominate sporting activities involving overhead movements, and sports that put severe strain

the next few pages the joints and the muscular involvement of the shoulder, elbow, and wrist during bow shooting will be discussed in depth. As mentioned in the previous paragraph, the involvement of the upper extremity will be discussed in detail as it relates to its function in the action of shooting a bow. The shoulder plays a huge role in drawing the bow and keeping the string pulled back. The joints of the shoulder are vital when performing these actions. The joints involved include: the
