Myofascial pain is associated with muscle tenderness that arises from trigger points, focal points of tenderness, a few millimeters in diameter, found at multiple sites in a muscle and the fascia of muscle tissue. Biopsy tests found that trigger points were hyperirritable and electrically active muscle spindles in general muscle tissue.
The trapezius muscle (pl.: trapezii) is a surface muscle of back, shown in red above and below. Details. Origin. Medial one-third of superior nuchal line, external occipital protuberance, spinous processes of vertebrae C7-T12, Nuchal ligament [1] Insertion. Posterior border of the lateral one-third of the clavicle, acromion process, and spine ...
Accessory nerve disorder. Other names. Spinal accessory nerve palsy. Muscles innervated by the accessory nerve. Specialty. Neurology. Accessory nerve disorder is an injury to the spinal accessory nerve which results in diminished or absent function of the sternocleidomastoid muscle and upper portion of the trapezius muscle.
The cause is believed to be muscle tension or spasms within the affected musculature. [1] Diagnosis is based on the symptoms and possible sleep studies. [1] Treatment may include pain medication, physical therapy, mouth guards, and occasionally benzodiazepine. [1] It is a relatively common cause of temporomandibular pain. [1]
Tension myositis syndrome (TMS), also known as tension myoneural syndrome or mindbody syndrome, is a name given by John E. Sarno to what he claimed was a condition of psychogenic musculoskeletal and nerve symptoms, most notably back pain. [1][2][3] Sarno described TMS in four books, [4][5][6][7] and stated that the condition may be involved in ...
A self-limiting spontaneously occurring form of torticollis with one or more painful neck muscles is by far the most common ('stiff neck') and will pass spontaneously in 1–4 weeks. Usually the sternocleidomastoid muscle or the trapezius muscle is involved. Sometimes draughts, colds, or unusual postures are implicated; however, in many cases ...
v. t. e. The accessory nerve, also known as the eleventh cranial nerve, cranial nerve XI, or simply CN XI, is a cranial nerve that supplies the sternocleidomastoid and trapezius muscles. It is classified as the eleventh of twelve pairs of cranial nerves because part of it was formerly believed to originate in the brain.
A fasciculation, or muscle twitch, is a spontaneous, involuntary muscle contraction and relaxation, involving fine muscle fibers. [1] They are common, with as many as 70% of people experiencing them. [1] They can be benign, or associated with more serious conditions. [1] When no cause or pathology is identified, they are diagnosed as benign ...
