The sternocleidomastoid muscle is located in the neck and is both a neck rotator and flexor. Cervical dystonia, a focal dystonia disorder, is characterized by forceful involuntary contraction of a group of neck muscles, usually including the sternocleidomastoid. Little is known about the fiber type composition, fiber type compartmentalization and innervation patterns in this muscle in rabbit an...

The purpose of this study is to reveal the relationship between the head position, and the neck and head muscles. At 4 head positions, the activities of masseter, anterior temporal, anterior digastric, sternocleidomastoid and trapezius muscle of ten normal subjects standing straight were investigated electromyographically with surface electrodes during voluntary maximal clenching in centric occ...

Background: In prior studies, there has been no report of clinical observation postoperative reconnection the sternocleidomastoid muscle (SCM) in children with congenital muscular torticollis (CMT). Therefore, objective this study is to investigate factors associated SCM CMT, and provide evidence.

The sternocleidomastoid, a prominent landmark of neck, offers protection to the major blood vessels and the nerves of this region. In recent era, this muscle has received a great attention of oncologists, general surgeons and plastic surgeons as it can be used as an excellent myocutaneous flap in reconstructive surgeries of head and neck region. The sternocleidomastoid is the key muscle of the ...

OBJECTIVE Cervical vestibular evoked myogenic potentials (cVEMPs) are short-latency electromyogram (EMG) evoked by high-level acoustic stimuli recorded from the activated sternocleidomastoid muscle and used to evaluate otolith organ function. The purpose of this study was to investigate the effects of aging on the cVEMP and on the sternocleidomastoid muscle EMG level. DESIGN A cross-sectional...

Introduction Most patients after either superficial or total parotidectomy develop facial deformity and Frey syndrome, which leads to a significant degree of patient dissatisfaction. Objective Assess the functional outcome and esthetic results of the superiorly based sternocleidomastoid muscle (SCM) flap after superficial or total parotidectomy. Methods A prospective cohort study for 11 patient...

background: workstation design has shift from using single monitor screen to dual monitor screens, which may impose some impacts towards the muscles activity. this study aimed to determine the effect of using dual monitor screen computer to the neck-shoulder muscle activity among computer user. method: this experimental study was conducted in 2015 among 28 healthy students in university malaysi...

diabetes mellitus type ι is a metabolic disorder that affects multiple systems including the inner ear. patients with diabetes mellitus commonly complain about dizziness, floating sensation, tinnitus and sweating. the aim of this study was to compare vestibular evoked myogenic potentials (vemps) between diabetic patients with or without neuropathy. subjects included 14 patients with diabetes me...
