  2. Obligatory synergies - Wikipedia

    en.wikipedia.org/wiki/Obligatory_synergies

    The extension synergy for the upper extremity includes scapular protraction, shoulder adduction and internal rotation, elbow extension, forearm pronation, and wrist and finger flexion. [ 1 ] The flexion synergy for the lower extremity includes hip flexion, abduction and external rotation, knee flexion, ankle dorsiflexion and inversion and toe ...

  3. Pull-down (exercise) - Wikipedia

    en.wikipedia.org/wiki/Pull-down_(exercise)

    The standard pull-down motion is a compound movement that requires dynamic work by muscles surrounding the three joints which move during the exercise. These are the elbow in conjunction with the glenohumeral and scapulothoracic joints in the shoulder girdle.

  4. Rear delt raise - Wikipedia

    en.wikipedia.org/wiki/Rear_delt_raise

    The movement is primarily limited to the two shoulder joints: the glenohumeral joint and the scapulothoracic joint. Scapular movement will also cause movement in the sternoclavicular joint and acromioclavicular joint. If the elbow bends during the extension exercises, it gravitates into a rowing motion.

  5. Deltoid muscle - Wikipedia

    en.wikipedia.org/wiki/Deltoid_muscle

    The intermediate fibers perform basic shoulder abduction when the shoulder is internally rotated, and perform shoulder transverse abduction when the shoulder is externally rotated. They are not utilized significantly during strict transverse extension (shoulder internally rotated) such as in rowing movements, which use the posterior fibers.

  6. Rhomboid major muscle - Wikipedia

    en.wikipedia.org/wiki/Rhomboid_major_muscle

    The implications of scapular instability caused by the rhomboid major include scapular winging during scapular protraction, excessive lateral rotation and depression of the scapula, as the antagonistic action by the rhomboid major is absent. With scapular instability, movement in the upper extremity is limited as the scapula cannot guide the ...

  7. Shoulder - Wikipedia

    en.wikipedia.org/wiki/Shoulder

    Shoulder anatomy, front view Shoulder anatomy, back view. The rotator cuff is an anatomical term given to the group of four muscles and their tendons that act to stabilize the shoulder. [3] These muscles are the supraspinatus, infraspinatus, teres minor and subscapularis and that hold the head of the humerus in the glenoid cavity during ...

  8. Face pull (exercise) - Wikipedia

    en.wikipedia.org/wiki/Face_pull_(exercise)

    At the glenohumeral joint, movement of the humerus is performed by a combination of transverse abduction, by the posterior and lateral deltoids, [3] and external rotation, by the infraspinatus and teres minor. [4] At the scapulothoracic joint, the middle and lower fibers of the trapezius and the rhomboids contract to perform retraction of the ...

  9. Rotator cuff - Wikipedia

    en.wikipedia.org/wiki/Rotator_cuff

    Avoiding movement of the shoulder joint allows the torn tendon to fully heal. [24] Once the tendon is entirely recovered, passive exercises can be implemented. Passive exercises of the shoulder are movements in which a physical therapist maintains the arm in a particular position, manipulating the rotator cuff without any effort by the patient ...
