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 anterior strength and the quantity of scapular upward rotation. DESIGN Descriptive study. SETTING…

Shoulder Adaptations Among Pitchers and Position Players Over the Course of a Competitive Baseball Season
TLDR
These results suggest that baseball position players develop more scapular upward rotation over the course of a competitive season than pitchers, which may increase the pitchers' risk of injury and may partially explain their higher incidence of shoulder injury compared with position players.
Assessment of scapulohumeral rhythm for scapular plane shoulder elevation using a modified digital inclinometer.
TLDR
Clinically, the usefulness of the inclinometer must be recognized in documenting the variable nature of scapulohumeral rhythm in healthy and injured shoulders.
The comparison of scapular upward rotation and scapulohumeral rhythm between dominant and non-dominant shoulder in male overhead athletes and non-athletes.

TLDR
Decreased dominant ER, higher deficit of dominant eccentric ER peak torques, and higher dominant rotator fatigability correlate with previous shoulder pain/injury, and individually adjusted shoulder training is recommended.
The effects of scapular kinematics, glenohumeral range-of-motion, and shoulder muscle strength on kinematics and kinetics of maximum effort baseball throwing
TLDR
Positive correlations were observed between scapular kinematics during scaption and throwing at the same arm elevation angle at stride foot contact and the occurrence of maximum shoulder compression force, indicating that kinematic patterns that appeared duringscaption also appeared during throwing.
Does scapula stabilizing t-shirt help over-head athletes in shoulder discomfort? A randomized control study.
TLDR
It is underlines that scapula-stabilizing t-shirt can have positive effects on shoulder discomfort in over-head athletes and shows a better clinical outcome at T1 which increased in T2 for pitchers in Group A, while in Group B athletes these positive results were not observed.
Analysis of recruitment of the superficial and deep scapular muscles in patients with chronic shoulder or neck pain, and implications for rehabilitation exercises
TLDR
A standard set of test positions for normalization of scapulothoracic electromyographic data that also incorporates the Levator Scapulae, Pectoralis Minor, and Rhomboid Major muscles is one step toward a more comprehensive understanding of normal and abnormal muscle function of these muscles.
Influence of a Single Swim Training on the Scapular Position and Isometric Muscle Strength in Young Swimmers
TLDR
Adolescent swimmers did employ higher values for the serratus anterior than for the upper trapezius, and the lateral displacement of the scapula increased significantly after the training, but none of the strength parameters changed significantly as a result of the single swim training.
Risk factors associated with subacromial pain in young athletes: A case control study.
TLDR
Logistic regression analysis showed that the variable representing the physiological functioning of the sternoclavicular joint and the grade of shortening of the clavicular portion of the pectoralis major were good predictors for presence of SAP.
Relationship between the observation of types of scapular dyskinesis and peak muscle activity of the scapular stabilizing muscles
TLDR
An observational descriptive study design investigating physically active, injury-free individuals to investigate the relationship between the peak activity of the three main scapular stabilizing muscles and identifying types ofScapular dyskinesis.

Recruitment patterns of the scapular rotator muscles in freestyle swimmers with subacromial impingement.
TLDR
A relationship does exist between shoulder injury and the temporal recruitment patterns of the scapular rotators, such that injury reduces the consistency of muscle recruitment, and the findings suggest that injured subjects have muscle function deficits on their unaffected side.
Scapular dysfunction in throwers with pathologic internal impingement.
TLDR
Based on the results of this study, throwing athletes diagnosed with pathologic internal impingement present with statistically significant increases in sternoclavicular elevation and scapular posterior tilt position during humeral elevation in theScapular plane.
Clinical Measures of Shoulder Mobility in the Professional Baseball Player.
TLDR
Evaluated clinical measures of shoulder mobility in professional baseball players in order to examine differences between the throwing and the nonthrowing shoulders and to describe chronic adaptations to throwing to determine the relation of these adaptive changes, if any, to shoulder injury and disability.
Scapular rotation in swimmers with and without impingement syndrome: practice effects.
TLDR
Abnormal scapular kinematics in swimmers with impingement syndrome may only be observed after an intense swim practice, and the examination of swimmers immediately after swimming may provide more information regarding impingements syndrome than a typical clinical exam.

TLDR
Known facts about the biomechanics of the scapula and surrounding muscles are presented and methods for evaluation of scapular muscle weakness are suggested and exercise techniques to maximally strengthen theScapular musculature are described.

TLDR
A biomechanical model of the shoulder girdle was proposed by correlating the results from the present study with the electrical activity of the scapular rotators, which is useful in demonstrating the true dynamic function of the muscles acting on theScapula as well as the mechanical efficiency of upward scapulohumeral rotation during arm abduction.
New method to assess scapular upward rotation in subjects with shoulder pathology.
TLDR
The "modified" digital inclinometer demonstratedGood to excellent intrarater reliability and good to excellent validity when measuring scapular upward rotation during static positions of humeral elevation in the scapULAR plane.
Shoulder function and 3-dimensional scapular kinematics in people with and without shoulder impingement syndrome.
TLDR
The kinematic differences found in subjects with impingement may represent scapulothoracic compensatory strategies for glenohumeral weakness or motion loss and support rehabilitation approaches that focus on strengthening and restoring flexibility.
Scapulothoracic motion in normal shoulders and shoulders with glenohumeral instability and impingement syndrome. A study using Moiré topographic analysis.
TLDR
Axioscapular muscle dysfunction is common with both instability and impingement syndrome of the shoulder, although it remains to be determined whether this represents a primary or secondary phenomenon.
