What is the action of the upper trapezius muscle?
The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade.
What is the action of the lower trapezius?
The lower trapezius works as a feedforward muscle prior to abduction to contract, and ‘hold’ the scapula steady to counteract the downward rotation ‘drag’ effect. It therefore neutralizes the scapula at the start of abduction.
Where is the trapezius action?
Trapezius Muscle Actions The trapezius is present in the neck, shoulders, back, and thorax regions. Most of its actions are in the shoulders, where the muscle inserts onto the scapula. When you shrug your shoulder, for example, you’re elevating the scapula.
How many actions does the trapezius have?
| Trapezius | |
|---|---|
| Nerve | accessory nerve (motor) cervical spinal nerves C3 and C4 (motor and sensation) |
| Actions | Rotation, retraction, elevation, and depression of scapula |
| Antagonist | serratus anterior muscle, Latissimus dorsi, Pectoralis Major |

What is the function of trapezius?
The trapezius muscle is mainly postural but is also used for active movements such as side bending and turning the head, elevating and depressing the shoulders, and internally rotating the arm. The trapezius elevates, depresses, and retracts the scapula.
What is the function of the trapezius?
Cranial nerve XI innervates the motor function of the trapezius. The function of the trapezius is to stabilize and move the scapula. The upper fibers can elevate and upwardly rotate the scapula and extend the neck. The middle fibers adduct (retract) the scapula.
What muscles are in the trapezius?
The trapezius muscle is a large muscle bundle that extends from the back of your head and neck to your shoulder….It is composed of three parts:
- Upper trapezius.
- Middle trapezius.
- Lower trapezius.
What is the function of the trapezius muscle?
The trapezius muscle is a postural and active movement muscle, used to tilt and turn the head and neck, shrug, steady the shoulders, and twist the arms. The trapezius elevates, depresses, rotates, and retracts the scapula, or shoulder blade. Innervation of the trapezius is derived from the spinal accessory nerve.
How can I reduce the pain in my trapezius muscle?
Pain in the shoulder and neck can be prevented or reduced with massage.It is possible to reduce trapezius muscle pain through self-massage. Reach back with one hand and find your trapezius muscle.
What causes pain in upper back Trapezius muscle?
A violent twist or collision that places excessive force on the upper back can lead to a trapezius muscle tear and pain. The muscle can get injured during contact sports, weightlifting, car collisions, and hard falls. The symptoms are usually felt immediately. The severity of the pain depends on the severity of the injury. 7
How is the right hand used in trapezius therapy?
The right hand stabilizes the lateral one third of the patient’s right clavicle and acromion palpating the muscle. The therapist then gently and slowly flexes, left side flexes and right rotates the mid and lower cervical spine with the left hand. The hand stabilizing and the hand moving the body part senses the tension in the muscle and barrier.
