What movements occur at the shoulder girdle?
The movements of the shoulder girdle include depression and elevation, upward rotation and downward rotation, as well as abduction and adduction. The clavicles rotate around their own axes when the scapula moves.
What are the 4 movements of the shoulder?
Adduction: downward movement of humerus medially toward the body from abduction, in the plane of the scapula. Flexion: the movement of humerus straight anteriorly. Extension: the movement of humerus straight posteriorly. External rotation: the movement of humerus laterally around its long axis away from the midline.
Where does most of the movement in the shoulder girdle occur?
scapulothoracic joint
All of these movements occur within the scapulothoracic joint. The acromioclavicular joint is made up of the flattened distal head of the clavicle, which fits into the medial aspect of the acromion process of the scapula.
What is shoulder girdle abduction?
Glenohumeral Abduction- A movement of the arm away from the midsagittal. plane of the trunk. This movement involves both glenohumeral joint motion. and movement of the shoulder girdle. The first 30° of abduction of the gleno-
What is the normal ROM for shoulder horizontal adduction?
Horizontal adduction may fall between 3 and 50° and shoulder flexion ranges from 165° to greater than 180°. These measures provide general ranges to guide clinical examination.
What is shoulder flexion and extension?
A shoulder flexion is when you move your arms anywhere from a resting position by your sides to straight above your head. An extension is when you move your arms and stick them out behind you. The muscles involved in the flexion movement include the anterior deltoid, pectoralis major and coracobrachialis.
How many planes of movement are possible at the shoulder?
three planes
Multiplanar or triaxial joints rotate in all three axes allowing movement in all three planes. The shoulder joint is an example of a multiplanar/triaxial joint.
What is normal shoulder abduction?
A normal range for abduction, starting with your palms at your sides, is around 150 degrees in a healthy shoulder. This places your hands above your head with your arms straight.
What movements are available for the pectoral girdle?
The movements available for the pectoral girdle or the scapula in particular includes: Protraction: moving the shoulder blade (scapula) forwards, away from the rib cage and spine. Retraction: this movement pulls the scapula back towards the rib cage. Elevation: movement that allows the shoulder girdle to move upwards as in shrugging the shoulders.
What is the range of motion for shoulder extension and abduction?
A normal range of motion for shoulder extension to the highest point you can lift your arm behind your back — starting with your palms next to your body — is between 45 and 60 degrees. Abduction occurs when you have arm movement away from the middle of your body.
What is the girdle of the shoulder?
The shoulder girdle is also called the pectoral girdle, and it is a bone ring, incomplete posteriorly. The shoulder girdle is formed by two sets of bones : the scapulae, posteriorly, the clavicles anteriorly and completed anteriorly by the manubrium of the sternum (part of the axial skeleton).
What is medial rotation of the shoulder?
Medial rotation. Imagine your body is a cabinet, your arms are the cabinet doors and you’re shutting the doors. This is medial rotation — also referred to as internal rotation — and the normal range of motion for a healthy shoulder is 70 to 90 degrees.
