The first aim of this investigation was to quantify the distribution of trapezius muscle activity with different scapular postures while seated. The second aim of this investigation was to examine the association between changes in cervical and scapular posture when attempting to recruit different subdivisions of the trapezius muscle. Cervical posture, scapular posture, and trapezius muscle act...

Context: Glenohumeral and scapular upward rotation are important factors in functional upper extremity motion. Objectives: To determine how different amounts of glenohumeral rotation (internal, external, and neutral) affect scapular upward rotation. Design: Controlled laboratory study. Independent variables were the amounts of internal, external, and neutral glenohumeral rotation. The dependent...

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 ...

BACKGROUND It is unclear whether the presence of scapular dyskinesis increases the risk of developing shoulder pain in asymptomatic athletes. OBJECTIVES To determine whether the presence of scapular dyskinesis in asymptomatic athletes increases the risk of developing shoulder pain by systematic review and meta-analysis. METHODS A systematic search was conducted in the Cochrane Library, Emba...

INTRODUCTION Scapular motion during arm elevation is frequently evaluated in patients with shoulder disorders because it provides clinically useful information. With the development of measurement devices and improvement in accuracy, comparisons under various conditions have recently been reported. However, in most of these reports, the subjects examined were limited to males, or a mixed popula...

The purpose of this study was to investigate the effects of a 6-week scapular upward rotation exercise (SURE) on scapular and clavicular alignment and scapular upward rotators strength in subjects with scapular downward rotation syndrome (SDRS). Seventeen volunteer subjects with SDRS were recruited from university populations. The alignment of the scapula and clavicle was measured using radiogr...

[Purpose] This study was performed to evaluate the clinical effect of the dual-wall pushup plus exercise in patients with scapular dyskinesis with a winged or tipped scapula. [Subject] A 32-year-old man with scapular dyskinesis participated in this study. [Methods] The subject performed the dual-wall pushup plus for 2 months, 4 days a week, for an average of 2 hours each day. The scapular dyski...
