7 Σεπ 2024 · Protraction & Retraction. Protraction describes the anterolateral movement of the scapula on the thoracic wall that allows the shoulder to move anteriorly. In practice, this is the movement of ‘reaching out’ to something.
An alternative testing position for internal and external glenohumeral joint rotation is prone with the shoulder at 90 degrees of abduction and the elbow at 90 degrees of flexion. The forearm hangs over the edge of the table.
30 Οκτ 2023 · Acting in conjunction with the pectoral girdle, the shoulder joint allows for a wide range of motion at the upper limb; flexion, extension, abduction, adduction, external/lateral rotation, internal/medial rotation and circumduction.
30 Οκτ 2023 · The shoulder girdle functions as the anchor that attaches the upper limbs to the axial skeleton. Additionally, the shoulder girdle allows for a large range of motion, mainly in the highly mobile scapulothoracic joint. This article will discuss the anatomy and functions of the shoulder girdle.
20 Ιουλ 2023 · Flexion and extension of the shoulder occur like this: Anatomical structures: The humerus of the arm moves relative to the scapula of the shoulder blade. Reference axes: The movement is in the sagittal plane. The fulcrum is provided by the shoulder, or glenohumeral joint, around a frontal axis.
7 Ιουν 2016 · INDICATIONS OF A POSITIVE TEST. Horizontal adduction, or cross flexion, normally is 130°. Failure to attain this position and/or pain during testing indicates a positive test result, most commonly a pathological condition of or localized pain in the acromioclavicular joint or sternoclavicular joint.
During right arm flexion: The upper thoracic vertebrae right side flexes, right rotates and extends. The first and second ribs descend, while the 4-6th ascend and the 3rd acts as an axis. Limitation of motion in any of these structures will adversely affect the biomechanics of the shoulder girdle and may produce or predispose the shoulder ...
