چکیده
[Purpose] This study investigated the changes in pressure pain threshold of the upper trapezius, levator scapular, and rhomboid muscles during continuous computer work. [Subjects] Fourteen males and females aged 26-32 years, were recruited. [Methods] A dolorimeter pressure algometer was used to measure the pressure pain threshold of the upper trapezius, levator scapular, and rhomboid muscles, respectively, before computer work and after 15 min, 30 min, and 60 min of computer work. [Results] The pressure pain threshold of the upper trapezius was significantly decreased after 15 min or more of computer work. The pressure pain threshold of the levator scapular was significantly decreased after computer work for 30 min and 60 min. The pressure pain threshold of the rhomboid muscle was significantly decreased after 60 min of computer work. [Conclusion] Continuous computer work could produce much more pain in the levator scapular and rhomboid muscle than the upper trapezius.

Background & Aims: Impingement syndrome is the most common injury and cause of movement limitations and pain in the shoulder area. The purpose of this study was to investigate the effect of eight weeks of focused scapular training on pain, electrical activity of shoulder muscles, and upper extremity performance in male volleyball players with shoulder impingement syndrome.

متن کاملTreatment of scapular winging with modified Eden-Lange procedure in patient with pre-existing glenohumeral instability.
Primary scapular winging typically results from palsies of the serratus anterior, trapezius, and rhomboid muscles, which are caused by injury to the long thoracic nerve, spinal accessory nerve, and dorsal scapular nerve, respectively. The Eden-Lange procedure has become the surgical treatment of choice for scapular winging from trapezius palsy because other surgical procedures have high failure...
متن کاملLevator scapulae and rhomboid transfer for paralysis of trapezius. The Eden-Lange procedure.
Spinal accessory nerve palsy leads to painful disability of the shoulder, carrying an uncertain prognosis. We reviewed the long-term outcome in 16 patients who were treated for pain, weakness of active elevation and asymmetry of the shoulder and the neck due to chronic paralysis of the trapezius muscle, as a result of nerve palsy. Of four patients who were treated conservatively, none regained ...
متن کاملThree-dimensional scapular orientation and muscle activity at selected positions of humeral elevation.
Abnormal scapular kinematics and associated muscle function presumably contribute to shoulder pain and pathology. An understanding of scapular kinematic and electromyographic profiles in asymptomatic individuals can provide a basis for evaluation of pathology. The purpose of this study was to describe normal three-dimensional scapular orientation and associated muscle activity during humeral el...
