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 ...

Medial scapular winging is often due to dysfunction of the serratus anterior muscle as a result of injury to the long thoracic nerve. Impairment of the serratus anterior muscle may cause uncoordinated scapulohumeral rhythm during shoulder elevation and subsequent subscapular or shoulder pain, subacromial impingement, and glenohumeral joint instability. Although long thoracic nerve injury typica...

[Purpose] To measure the activities of the upper, middle, and lower trapezius and serratus anterior muscles during shoulder abduction at two angles and compare their relative isolation. [Subjects and Methods] Ten men were enrolled. The tester measured the isolation ratios of upper, middle, and lower trapezius and serratus anterior muscles during shoulder abduction exercises at 60° and 120°. [Re...

Results and Discussion: On the basis of analysis of 45 articles we propose an anatomical classification of muscle-sparing thoracotomies considering the way in which the muscles are spared. Classification distinguishes five types of muscle-sparing thoracotomies which are represented originally using cylindrical projection of thorax. Type I is realized by enlarging auscultatory triangle, Type II ...

QUESTION Can real-time visual feedback facilitate the activity of serratus anterior in individuals with scapular winging during shoulder flexion? DESIGN Comparative, repeated-measures experimental study. PARTICIPANTS Nineteen subjects with scapular winging. INTERVENTION Participants performed isometric shoulder flexion at 60° and 90° with and without real-time visual feedback using a vide...

INTRODUCTION Isolated long thoracic nerve injury causes paralysis of the serratus anterior muscle. Patients with serratus anterior palsy may present with periscapular pain, weakness, limitation of shoulder elevation and scapular winging. CASE PRESENTATION We present the case of a 23-year-old woman who sustained isolated long thoracic nerve palsy during anterior spinal surgery which caused ext...

OBJECTIVE The aim of this study is to analyse the possibilities and the results of using the serratus anterior muscle flap during reoperations in patients with a complicated course after major general thoracic procedures. MATERIAL AND METHODS We performed a retrospective study on 25 consecutive patients operated in a single center between 01.01.2002-01.01.2012, in whom we used the serratus an...

Currently, notalgia paresthetica (NP) is a poorly-understood condition diagnosed on the basis of pruritus, pain, or both, in the area medial to the scapula and lateral to the thoracic spine. It has been proposed that NP is caused by degenerative changes to the T2-T6 vertebrae, genetic disposition, or nerve entrapment of the posterior rami of spinal nerves arising at T2-T6. Despite considerable ...

OBJECTIVES To determine the activity of the upper trapezius, serratus anterior, anterior deltoid, biceps brachii. and lower trapezius muscles in healthy adults during below-the-knee assembly work. METHODS Fifteen right-handed male subjects participated in this study. The electrical activities, measured by EMG, of the right upper trapezius, serratus anterior, anterior deltoid, biceps brachii. ...
