BACKGROUND The trapezius muscle is a neck muscle that is susceptible to chronic pain conditions associated with repetitive tasks, commonly referred to as chronic work-related myalgia, hence making the trapezius a muscle of clinical interest. To provide a basis for further investigations of the proteomic traits of the trapezius muscle in disease, two-dimensional difference gel electrophoresis (2...

Introduction: An otogenic brain abscess is a common ENT problem but an otogenic trapezius abscess can also be experienced in otolaryngological practice, particularly in patients with chronic suppurative otitis media.   Case Report: We report a rare case of a trapezius abscess in an eight-year-old girl who presented at the ENT, Head and Neck Surgery Postgraduate Medical Institute, Lady Readi...

The trapezius muscle is one of the largest muscles in the body. It is one of the most superficial muscles in the posterior aspect of the neck and thorax. The trapezius flap had been used frequently, but has been used less often in recent years. Still, a trapezius flap can be used in a number of ways in the reconstruction of the upper back or head and neck. The authors noted that the flap could ...

Descending necrotizing mediastinitis (DNM) is a rare form of mediastinal infection. Most cases are associated with esophageal rupture. DNM after a trigger point injection in the upper trapezius has not been described previously. We present a case of DNM after a trigger point injection in the upper trapezius. A 70-year-old man visited the emergency department with chest discomfort and fever afte...

background: most dentists complain of musculoskeletal disorders which can be caused by prolonged static posture, lack of suitable rest and other physical and psychological problems. objective: we evaluated a chair with a new ergonomic design which incorporated forward leaning chest and arm supports. methods: the chair was evaluated in the laboratory during task simulation and emg analysis on 12...

BACKGROUND Different research techniques indicate alterations in muscle tissue and in neuromuscular control of aching muscles in patients with chronic localized pain. Ultrasound can be used for analysis of muscle tissue dynamics in clinical practice. AIM This study introduces a new muscle tissue sensitive ultrasound technique in order to provide a new methodology for providing a description o...

BACKGROUND Archery related injuries, such as shoulder impingement syndrome are caused by repeated motion of the shoulder. The aim of this study was to analyze differences in the shoulder kinematics and the associated muscle activity between archers with shoulder impingement and uninjured archery players. METHODS Thirty male archers, who were divided into an impingement group and an uninjured ...

Work-related chronic neck pain is a growing disorder in the United States that accounts for approximately 60% of all occupational disabling injuries [1]. Neck pain is linked to continuous and excessive activation in the upper trapezius (UT) muscle [2]. An effective treatment for chronic neck pain may be to reduce activation in the UT through an inferior shift in the muscle activity to the middl...
