  Trapezius Trigger Points
The Trapezius is a major source of headache pain, typically the type of pain experienced as a “tension headache.” It can also be a cause of dizziness, jaw, and toothache pain.
If neck massage does not relieve the sensation of tightness in the neck, Trigger Points in the Trapezius are the most likely culprit.
Referred pain from the Trapezius can be found in such a wide variety of locations, that it commonly leads to misdiagnosis, including shoulder bursitis, headaches, disc compression, or a “pinched nerve.” Using the Pressure Pointer may help alleviate your symptoms.

  Trapezius muscle - Encyclopedia, History, Geography and Biography
Trapezius gets its name from its trapezium-like shape; the corners being the neck, the two shoulders, and the thoracic vertebra, T12.
It arises from the external occipital protuberance and the medial third of the superior nuchal line of the occipital bone, from the ligamentum nuchæ, the spinous process of the seventh cervical, and the spinous processes of all the thoracic vertebræ, and from the corresponding portion of the supraspinal ligament.
The two Trapezius muscles together resemble a trapezium, or diamond-shaped quadrangle: two angles corresponding to the shoulders; a third to the occipital protuberance; and the fourth to the spinous process of the twelfth thoracic vertebra.

The remaining insertions of the trapezius are elevated from the clavicle and the scapular spine to 2 cm from the vertebral border of the scapula.
Trapezius, levator scapulae and rhomboid muscles remain healthy or recover in 96% of cases, therefore are available for transposition.
Trapezius transfer to treat flail shoulder after a brachial plexus injury will allow the patient to position the arm much better, even when functional recovery is not adequately strong to keep the shoulder stable.

A person can feel the muscles of the trapezius become active by holding a weight in front of them in one hand, and with the other, touching the area between the shoulder and the neck.
It is common for non-experienced gym users to focus mostly to the upper portion of the muscle, and thus forgotting important middle part and creating muscle imbalances which can heavily affect posture and for example shoulder health.

Like the sternocleidomastoid, the trapezius is a compound muscle consisting of three distinct parts, as indicated by a more or less clear separation of the clavicular portion of the muscle from the rest and, less frequently, by the separation of the lower from the middle portion.
Variations likewise occur in the extent of the spinal attachments of trapezius, owing to the the reduction of one or another of its parts; this attachment usually extends lower in the muscle on the right side than in that on the left.

 The Upper Trapezius DOES NOT Elevate the Shoulder
The authors state that because of this mechanism, "the weight of the upper limb and any weight it carries are not borne by the cervical trapezius." The transverse UT fibers balance the movement caused by the vertical load on the shoulder, which is transferred to the sternoclavicular joint.
So, the trapezius resists lateral, instead of downward load, which is why the trapezius (C2-C6) only has to be anchored to the ligamentum nuchae, instead of the cervical spine.
The upper trapezius, therefore, is not an elevator of the scapula, but uses the sternoclavicular joint to sustain downward loads applied to the upper limb.

 CHAPTER 4: MATERIAL AND METHODS
Figure 4.3.c shows the RMS trend of upper trapezius in position B. The RMS behavior of middle trapezius for position B was variable between the subjects, probably due to the fact that it was hard for individuals to control the amount of shoulder retraction.
The RMS value of upper trapezius increased significantly in all healthy subjects while the muscle was acting as a stabilizing synergist; however, its behavior in patients was variable.
However, the finding of a significant difference in the RMS behavior of trapezius between the patients and healthy subjects while the muscle was acting as a stabilizing synergist and, during the same experiment finding that the endurance time between the two groups was not significantly different, may indicate a physiological change in the myalgic muscle.

The large muscles involved in shoulder movement are trapezius, deltoid, serratus anterior, pectoralis major and minor, assisted by the smaller muscles teres major, the rhomboids and levator scapulae..
Purpose: To evaluate the timing of trapezius muscle activity in response to an unexpected arm movement in athletes with impingement and in normal control subjects.

 Rhytmic activity associated with respiration in both trapezius muscles
Examination of both trapezius muscles and the right sternocleidomastoid muscle by means of concentric needle electrodes revealed normal activity with normal motor unit action potentials and without any spontaneous activity apart from the rhythmic activity obtained from trapezius muscles at rest.
The rhythmic pattern of activity observed in trapezius muscles was harmonic, continuous and associated with the rhythm of respiration (Figure 1).
In normal subjects, the role of the trapezius muscle in respiration seemed to be minimal in spite of the cervical plexus contribution and rhythmic respiration in resting condition is entirely diaphragmatic(15).

It is concluded that normal MVEP recorded on the trapezius muscles are bilateral and consist of four waves, the amplitude of which could depend on the simultaneous stimulation of both cochlear and vestibular afferents.
MEVP recorded on trapezius muscles were absent in the case of total cochleovestibular damage.

 Trapezius Exercises To Build Trapezius Muscle & Trapezius Exercises For Strength
Your trapezius muscles are more than likely relatively strong already even if you've never exercised before, and because of this you must use trapezius exercises with heavy weights in order to properly develop them.
Trapezius exercises using heavy weights must be handled with care and proper form otherwise the trapezius exercises you're using can easily injure your traps, shoulders or neck.
Overhead shrug trapezius exercises should be one of the first trap exercises you perform in your trapezius exercises program.

 Interstitial changes in trapezius muscle during repetitive low-force work
The aim of the present thesis was to determine the interstitial trapezius muscle responses to repetitive low-force work in healthy subjects and in patients with work-related trapezius myalgia - with respect to metabolism, inflammatory mediators and potential algesic substances.
It was demonstrated that metabolites accumulate in the trapezius muscle during 20 min of repetitive low-force work.
Finally, and perhaps most important of all, work-related trapezius myalgia was shown to be associated with increased anaerobic metabolism as well as increased levels of potential algesic substances (serotonin, glutamate) that correlated with pain intensity - indicating that peripheral nociceptive processes could be activated.
