What type of joint is Scapulohumeral?

What type of joint is Scapulohumeral?

Abduction requires coordinated movement of the glenohumeral joint and the scapulothoracic articulation and this is called the scapulohumeral (or scapulothoracic) rhythm. The purpose of the scapulohumeral rhythm is two-fold.

Where is Scapulohumeral joint located?

The sternoclavicular joint is located where the clavicle meets the sternum at the top of the chest. The scapulothoracic joint is sometimes considered a joint. It is located where the scapula glides against the thoracic rib cage at the back of the body. No ligaments connect the bones at this joint.

What is the function of Scapulohumeral rhythm?

Scapulohumeral rhythm serves two purposes: It preserves the length-tension relationships of the glenohumeral muscles. Muscles do not shorten as much as they would without the scapula’s upward rotation, and so can sustain their force production through a larger portion of the range of motion.

Is glenohumeral joint Same as Scapulohumeral joint?

[1] The glenohumeral articulation involves the humeral head with the glenoid cavity of the scapula, and it represents the major articulation of the shoulder girdle. [2] The latter also includes minor articulations of the sternoclavicular (SC), acromioclavicular (AC), and scapulothoracic joints.

What is Scapulohumeral rhythm?

Scapulohumeral rhythm: the coordinated motion of the scapula and humerus experienced during shoulder movement and motion that has been traditionally viewed as occurring at a ratio of 2:1 (2 degrees of humeral flexion/abduction to 1 degree of scapular upward rotation).

What muscles are involved in Scapulohumeral rhythm?

Latissimus Dorsi and m. Levator Scapulae, shortening of the posterior joint capsule and/or lack of coordination between essential muscles like the m. Serratus Anterior, m. Trapezius and Rotator cuff muscles.

What is the supraspinatus tendon?

The supraspinatus tendon is located on the back of your shoulder and helps your arm to move throughout its full range of motion – and helps with power and strength.

How can I improve my Scapulohumeral rhythm?

Hold a barbell with the hand placed as far away as comfortably possible. This will place the arm in some abduction and the scapula in upward rotation. Slowly elevate the scapula towards the ear. Perform three sets of 20 slow repetitions with a hold.

What is glenohumeral joint arthritis?

Glenohumeral joint arthritis is caused by the destruction of the cartilage layer covering the bones in the glenohumeral joint. This creates a bone-on-bone environment, which encourages the body to produce osteophytes (bone spurs).

What does supraspinatus mean?

The supraspinatus is a muscle located at the top of the shoulder. It is one of the four muscles of the rotator cuff and helps with arm abduction (raising the arms up and away from the body).

How do you fix supraspinatus?

Toward the back of the shoulder is the supraspinatus tendon and muscle….Common Treatments for Shoulder and Supraspinatus Muscle Injuries include:

1. Rest.
2. Ice.
3. Anti-Inflammatory Medication.
4. EPAT Therapy Treatment.
5. Kinesiology Tape (KT Tape) or Shoulder Sling.
6. Physical Therapy.
7. Corticosteroid Injection.
8. Rotator Cuff Surgery.
