Background: Despite the association of masticatory function with head posture and mandible movement, impact on masseter muscle electrical activity remains unclear. This study aimed to investigate anterior temporal, masseter, superior trapezius, sternocleidomastoid muscles in temporomandibular disorder (TMD) patients three different positions compare findings those for healthy subjects.

The silent period induced by transcranial magnetic stimulation of the sensorimotor cortex (Magstim 200, figure of eight coil, loop diameter 7 cm) in active muscles supplied by cranial nerves (mentalis, sternocleidomastoid, and genioglossus) was studied in 14 control subjects and nine patients with localised lesions of the sensorimotor cortex. In the patients, measurements of the silent period w...

[Purpose] This study aimed to simultaneously investigate the activities of the sternocleidomastoid muscle and scalenus anterior muscle, which are agonists of neck and breathing accessory muscles, by implementing breathing exercises. [Subjects and Methods] Thirteen subjects were selected for the experimental group, which performed feedback respiratory exercises with McKenzie exercises, and 12 su...

Fibromatosis colli or sternocleidomastoid tumor of infancy is a condition of benign proliferation of fibrous tissue within the sternocleidomastoid muscle leading to focal or diffuse enlargement of the sternocleidomastoid muscle and is often clinically associated with torticollis. Radiological imaging especially ultrasound, if performed by an expert radiologist plays an important role in differe...

Direct intramuscular injection of doxorubicin results in permanent myofiber loss. A previous phase I trial demonstrated that such injections could successfully treat blepharospasm and hemifacial spasm. Our previous in vitro study demonstrated that doxorubicin resulted in a dose-dependent reduction in isometric force generation in sternocleidomastoid muscle in rabbits. This present study examine...

[Purpose] The purpose of this study is to determine the effect that secondary postural deformities and chronic postural abnormalities have on lung capacity, as well as correlate the activity of the respiratory muscles. The results provide basic objective data about the forward head posture and respiratory muscle activity that can be used in clinical situations. [Subjects and Methods] The subjec...
