What is scapular protraction?

What is scapular protraction?

What Is Scapular Protraction? Also called abduction of the scapula, this is when the scapulae move laterally away from the spine. It is essentially the opposite of scapular retraction. The muscles involved in shoulder abduction are the serratus anterior, pectoralis major, and pectoralis minor.

Why is scapular protraction important?

[Conclusion] The adjustment of scapula into its ideal position through active scapular protraction increased the activations of the muscles surrounding the shoulder joint and improved the function of the upper extremity.

What happens to scapula during protraction?

Protraction of the scapula is sometimes called abduction of the scapula. The scapula is moved laterally and anteriorly along the chest wall. Muscles: serratus anterior is the prime mover. Pectoralis minor and major, the latter acting through the humerus, may assist (act as synergists).

What muscle causes scapular protraction?

Due to the multiple attachment sites, the primary role of the serratus anterior is to stabilize the scapula during elevation and to pull the scapula forward and around on the thoracic cage. Advancement of the scapula to an anterior position on the thoracic cage is termed protraction or scapular abduction.

What muscles do scapular protraction?

Protraction is accomplished by the actions of the serratus anterior, pectoralis major, and pectoralis minor muscles. Retraction is accomplished by the actions of the trapezius, rhomboids, and latissimus dorsi muscles. The elevation is accomplished by the trapezius, levator scapulae, and rhomboid muscles.

What may a winged scapula indicate?

The most common etiology of a winged scapula is usually due to damage or impaired innervation to the serratus anterior muscle. The nerve that innervates this muscle is the long thoracic nerve. Sometimes, this nerve can be damaged or impinged, leading to malfunction of the serratus anterior muscle.

What is protraction movement?

Protraction is movement of a body part in the anterior direction, i.e. being drawn forwards. The movement of protraction is the opposite of the movement of retraction.

What does scapular retraction help with?

This is a strengthening movement for the scapular (shoulder blade) and the back of the shoulder. If you have pain with the shoulder joint in the back or a restriction in the front of the shoulder, this is an excellent exercise for improved posture and upper back strength.

What is the main function of the scapula?

The scapula is an important bone in the function of the shoulder joint. It engages in 6 types of motion, which allow for full-functional upper extremity movement including protraction, retraction, elevation, depression, upward rotation, and downward rotation.

How to strengthen scapula muscle?

Upper Trapezium. People with weakness in the upper trapezium will often present with collarbones that are horizontal rather than the normal position of “slightly pitched.” View the “Shoulder Shrugs”

  • Serratus anterior. This muscle originates on the underside of the shoulder blade and attaches on to the ribcage.
  • Lower trapezium/middle trapezium.
  • What are the best exercises for the scapula?

    Start by standing in a doorway while keeping your one foot in front of the other. Ensure that your feet are pointing forward all the time.

  • Place your forearms on the doorway while making sure that your arms are making a 90-degree angle.
  • Slowly shift your weight forward,toward your front foot and let your shoulder blades pull together.
  • What muscles protract the scapula?

    Suprascapular artery – a branch of the thyrocervical trunk,which in turn arises from the subclavian artery.

  • Posterior circumflex humeral artery – a branch of the axillary artery supplying the glenohumeral joint
  • Circumflex scapular artery – originating from the subscapular artery,which in turn is a branch of the axillary artery
  • Which muscles upwardly rotate the scapula?

    The trapezius muscle adducts and upwardly (laterally) rotates the scapula.

  • The upper fibers are more suited for movement,and elevate the scapula.
  • The middle and lower fibers maintain the vertical and horizontal position of the scapula rather than generate torque.
