An example of trapezius function is an overhead press. When activating together, the upper and lower fibers also assist the middle fibers (along with other muscles such as the rhomboids) with scapular retraction/adduction. The trapezius also assists in abduction of the shoulder above 90 degrees by rotating the glenoid upward.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
The narrower the grip the more the trapezius muscles are exercised, as opposed to the deltoids. Barbells , dumbbells , kettlebells or a cable machine can be used. Due to the amount of internal rotation of the humerus during this movement, this exercise may worsen shoulder impingement syndrome.
In weight training, the shoulder shrug (usually called simply the shrug) is an exercise used to develop the upper trapezius muscle. [ 1 ] [ 2 ] Form and execution
The accessory nerve is tested by evaluating the function of the trapezius and sternocleidomastoid muscles. [8] The trapezius muscle is tested by asking the patient to shrug their shoulders with and without resistance. The sternocleidomastoid muscle is tested by asking the patient to turn their head to the left or right against resistance. [8]
the trapezius squeeze - which involves gripping and twisting a portion of the trapezius muscle in the patient's shoulder [1] mandibular pressure - this is the manual stimulation of the mandibular nerve , located within the angle of the jaw
The original technique was first described by Eden [4] in 1924 and verified by Lange in the 1950s. [5] [6] The rhomboid major and rhomboid minor were transferred laterally from the medial border of the scapula to the infraspinatous fossa, and the levator scapulae was transferred laterally to the spine of the scapula, near the acromion.
