“…18 The distance of posterior displacement of the ROS and IFA of the scapula from the thoracic wall was measured with a scapulometer to represent the degree of scapular dyskinesis. 9 The ICC values for intrarater reliability were in the range of 0.996 to 0.998 (SEM, 0.2-0.3 mm; MDC 95 , 0.6-0.7 mm) in this study, and those for interrater reliability were 0.95 to 0.99 (SEM, 0.7-0.8 mm) in previous research. 9 Detailed information of the conscious control program has been presented previously.…”

Background: Predictive variables associated with the effects of a scapular conscious control program should be identified and used to guide rehabilitation programs. Purpose: To determine whether potential factors are associated with the success of scapular muscle balance with an early control program in patients with subacromial pain and scapular dyskinesis. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 38 amateur overhead athletes with subacromial pain and medial border prominence were recruited. They performed progressive conscious control of scapular orientation during 45° and 90° of arm elevation. Stepwise logistic regression and receiver operating characteristic curve were used to determine the optimal cutoff point of related factors for success or failure of the program. Potential factors including pain level during activity, pain duration, anterior/posterior shoulder flexibility, forward shoulder posture, posterior displacement of root of spine and inferior angle, scapular kinematics, and muscle activation before conscious control program were recorded as independent variables. Successful control defined as decreases of the upper trapezius/serratus anterior ratio in 2 consecutive trials of the 90° program or failure in the program was used as a dependent variable. Results: Having a posterior displacement of the inferior angle of the scapula of ≤16.4 mm and scapular posterior tipping during arm elevation of ≤3.3° (collected before the control program) were associated with the success of the program ( R 2 = 0.286; P < .05). Additionally, participants with each or both variables present at baseline had probabilities of success of 78% and 95%, respectively. Conclusion: The value of scapular posterior displacement and posterior tilt should be considered before early scapular control program. Other factors related to the success of the program should be found due to the limited variance explained in the regression model.

“…1). This scapulometer-based screening method was designed to measure the distance from the inferior angle to the thorax wall, and has been estimated to have excellent reliability (intra-rater and inter-rater correlation coefficient) and fair validity (Du et al, 2017). Table 1 shows the demographic data of the participants.…”

“…However, a reliable clinical method to diagnose SD has not yet been developed because of (i) difficulties in observing scapular motions in multiple plans without other muscles and soft tissues and (ii) the absence of clinical assessment compared to a standard for quantifying SD [22]. Some clinical methods have been described with good reproducibility, even though their validity and reliability require further investigations [12,55,[90][91][92][93][94][95]. A simple field-based test measuring winging, a lack of control during shoulder motions, and scapula asymmetry, has shown high reliability in musculoskeletal pre-participation screening [96].…”

“…However, a clinical evaluation seems to be appropriate only in the diagnosis of dyskinesis type I because of a lack of evidence of the effectiveness for type II and III [64,105]. To quantify the features of SD types I and II, a novel scapulometer has been investigated, resulting in an excellent reliability and validity [95]. Furthermore, through plain-film radiography, the coracoid upward shift distance and length of the scapular spine line could be measured; differences in each parameter between the two sides can be correlated to type I and type II of SD, respectively [106].…”

Background: This study intends to summarize the causes, clinical examination, and treatments of scapular dyskinesis (SD) and to briefly investigate whether alteration can be managed by a precision rehabilitation protocol planned on the basis of features derived from clinical tests. Methods: We performed a comprehensive search of PubMed, Cochrane, CINAHL and EMBASE databases using various combinations of the keywords “Rotator cuff”, “Scapula”, “Scapular Dyskinesis”, “Shoulder”, “Biomechanics” and “Arthroscopy”. Results: SD incidence is growing in patients with shoulder pathologies, even if it is not a specific injury or directly related to a particular injury. SD can be caused by multiple factors or can be the trigger of shoulder-degenerative pathologies. In both cases, SD results in a protracted scapula with the arm at rest or in motion. Conclusions: A clinical evaluation of altered shoulder kinematics is still complicated. Limitations in observing scapular motion are mainly related to the anatomical position and function of the scapula itself and the absence of a tool for quantitative SD clinical assessment. High-quality clinical trials are needed to establish whether there is a possible correlation between SD patterns and the specific findings of shoulder pathologies with altered scapular kinematics.
