What are the following muscles would be most appropriate to activate for impairment of scapular winging during push up assessment?

Serratus anterior

The serratus anterior is a thin, fan-shaped muscle that originates from the first eight or nine ribs and inserts onto the medial border of the scapula. It is innervated by the long thoracic nerve.

The serratus anterior is responsible for protracting (pulling forward) the scapula and stabilizing it against the chest wall. It also assists in upward rotation of the scapula.

Pectoralis minor

The pectoralis minor is a small, triangular muscle that originates from the costal cartilage of the third, fourth, and fifth ribs and inserts onto the coracoid process of the scapula. It is innervated by the medial pectoral nerve.

The pectoralis minor is responsible for protracting and depressing the scapula. It also assists in downward rotation of the scapula.

Trapezius (middle and lower fibers)

The trapezius is a large, triangular muscle that originates from the occipital bone, the ligamentum nuchae, and the spinous processes of the seventh cervical and all thoracic vertebrae. It inserts onto the lateral third of the clavicle, the acromion process of the scapula, and the spine of the scapula. The trapezius is innervated by the accessory nerve and the cervical spinal nerves.

The middle and lower fibers of the trapezius are responsible for elevating and depressing the scapula, respectively. The upper fibers of the trapezius are responsible for shrugging the shoulders.

Rhomboids

The rhomboids are two small, diamond-shaped muscles that originate from the spinous processes of the second to fifth thoracic vertebrae and insert onto the medial border of the scapula. They are innervated by the dorsal scapular nerve.

The rhomboids are responsible for retracting (pulling backward) the scapula. They also assist in downward rotation of the scapula.

Levator scapulae

The levator scapulae is a long, thin muscle that originates from the transverse processes of the first four cervical vertebrae and inserts onto the superior angle of the scapula. It is innervated by the ventral branches of the third and fourth cervical spinal nerves.

The levator scapulae is responsible for elevating the scapula. It also assists in protracting and rotating the scapula.

These muscles would be most appropriate to activate for impairment of scapular winging during push up assessment because they are all involved in stabilizing the scapula against the chest wall and preventing it from winging out.
