CONTEXT Deficiencies in scapular upward rotation and periscapular strength have been associated with various shoulder pathologies and decreased athletic performance. Therefore, proper periscapular strength and concomitant scapular upward rotation are important factors among overhead athletes, such as baseball players. OBJECTIVE To assess the relationships between lower trapezius and serratus ...

[Purpose] The purpose of this study was to determine the effectiveness of strength and stretching exercises on upper crossed syndrome. [Subjects and Methods] After measuring cervical alignment using the Global Posture System, 30 students with forward head posture were selected and divided into two groups. The experimental group (n=15) participated in strength and stretching exercises, three tim...

[Purpose] In this study, we compared upper cervical flexion and cervical flexion angle of computer workers with upper trapezius and levator scapular pain. [Subject] Eight male computer workers with upper trapezius muscle pain and eight others with levator scapular muscle pain participated. [Methods] Each subject was assessed in terms of upper cervical flexion angle and total cervical flexion an...

[Purpose] This study investigated upper-extremity muscle activities in natural, ideal, and corrected head positions. [Subjects and Methods] Forty subjects with a forward head posture and rounded shoulder were recruited and randomly assigned to the natural head position group (n = 13), ideal head position group (n = 14), or corrected head position group (n = 13). Muscle activities were measured ...

parapharyngeal abscess is a life-threatening disease. upper respiratory tract infection is the main cause in children. we present a 15-month-old boy admitted to the emergency ward with the chief complaint of difficulty in breathing caused by parapharyngealabscess. his condition deteriorated gradually, and he transferred to the operation theater quickly for abscess drainage and because of the di...

The habitual activity patterns of trapezius and postural back muscles (multifidus, iliocostalis, longissimus) of 23 female subjects with moderate physical activity were studied. Bilateral surface electromyographic (sEMG) recordings from start of work until bedtime were analyzed. The activity level was calibrated as percentage of root mean square-detected muscle activity at maximal voluntary con...

Introduction: laptop bag may be a contributing factor for musculoskeletal complaints in schoolchildren. Several studies have reported an association between carrying heavily loaded schoolbags and musculoskeletal pain or discomfort. Methods: 105 collegiate students were conveniently recruited in this study. Electromyography (EMG) signals were recorded during the treadmill walking at a speed of 4...

[Purpose] The present study was performed to investigate whether forward head posture (FHP) affects muscle activity. [Subjects and Methods] Twenty subjects attending Y university in Gyeongsangnam-do, Republic of Korea. They were divided into two groups according to craniovertebral angle: a control group (n=10) and a FHP group (n=10). Electromyography electrodes were attached to the upper fibers...

[Purpose] The purpose of this study was to compare the upper, middle, and lower trapezius muscles' activity in the different planes of shoulder elevation. [Subjects] Twenty male subjects volunteered for this study. [Methods] Surface electromyographic (EMG) activity for each of the three regions of the trapezius muscles in the three different planes of elevation were collected while the particip...

ABSTRACT The management of post-radiation wound breakdown over the posterior cervico thoracic region can be a challenging task for a surgeon. The aim of the treatment is to produce a well vascularized and a low tensile flap which will close a large defect. We describe the use of the lower trapezius flap to reconstruct the wound breakdown and to obtain stable tissue coverage in a patient with po...
