BACKGROUND Central and peripheral mechanisms may be involved in migraine and tension-type headache pathogenesis, however the role of muscle disorders in their pathophysiological mechanisms remains unclear. OBJECTIVES To assess the association between the presence of migraine or tension-type headache and changes in longus colli muscle dimensions and sternocleidomastoid muscle activity. METHO...

Abstract Background Sarcopenia is increasingly recognised to impact the quality of life and patient outcomes. The relationship with brain frailty unknown. Objectives Assess if muscle mass at C3 correlates L3 on routine trauma imaging. for associations between muscle-mass, brain-frailty, Clinical Frailty Scale (CFS) Method Routine trauma-series CT scans were retrospectively analysed patients age...

OBJECTIVE This study evaluated the effect of a natural mediotrusive contact on the electromyographic (EMG) activity of the anterior temporalis and sternocleidomastoid muscles during chewing in healthy subjects. MATERIALS AND METHODS The study sample included two groups of 15 subjects each (Group 1: with natural mediotrusive contact; Group 2: without natural mediotrusive contact). Bilateral su...

Sternocleidomastoid muscle fibrosis has been recognized for centuries, but its pathogenesis and treatment remains controversial. Pseudotumor of infancy is a firm fibrous mass in the sternocleidomastoid muscle appearing at 2 to 3 weeks of age. Congenital muscular torticollis is less common and appears later in life. Pseudotumor and congenital muscular torticollis probably represent different man...

There are only few reports on the trigemino-cervical reflex in humans and there is debate over the best method of reflex examination. The aim of this study was, comparing different methods, to provide a reproducible method for evaluating the trigemino-cervical reflex. The trigemino-cervical reflex was studied in 32 healthy volunteers. The stimulation was applied to the supraorbital, infraorbita...

Intramuscular lipoma is rare benign tumour rarely located in the head and neck region. It arises between muscle fibres passes through intermuscular septa. Due to infiltrative nature of tumour, recurrence rate higher than other subcutaneous lipomas. Complete surgical excision often regarded as a definitive treatment modality longterm follow-up mandatory. Here we report case 49-year-old male pres...

Mechanical neck disorder is a widespread and non-neurological musculoskeletal condition resulting from modern lifestyles. Presently, the fundamental electrophysiological properties of the motor units of the sternocleidomastoid muscles and the characteristics of the short-term synchronization of the motor unit in patients with neck pain are ambiguous. This study therefore aims to clarify the fun...

The arterial baroreflex is crucial for short-term blood pressure control - abnormal baroreflex function predisposes to syncope and falling. Hypersensitive responses to carotid baroreflex stimulation using carotid sinus massage (CSM) are common in older adults and may be associated with syncope. The pathophysiology of this hypersensitivity is unknown, but chronic denervation of the sternocleidom...
