“…Results indicate that for a population of adolescent athletes with an amateur sports level, the dyskinesis prevalence is high; however, it is not associated with pain and does not seem to affect measures of upper limb function. Although some studies support the relationship between pain/ lesion and scapular dyskinesis 2,[7][8][9][10][11] , more than half of the current sample (56.7%) presented changes in scapular movement without, however, being associated with shoulder pain. The results of this study corroborate those of Oliveira et al 28 who analyzed amateur male athletes with shoulder injury syndrome and observed no association between dyskinesis and shoulder pain.…”

“…It has been well documented in the literature that movements at high speed, repetition, and load trigger joint adaptations such as disproportion between internal and external shoulder rotation amplitudes and changes in humeral and scapular positioning [1][2][3][4][5] . Specifically, the modification in the scapula positioning, called scapular dyskinesis, has been studied because it presents possible relations with the presence of pain and shoulder injuries in athletes 2,[6][7][8] . Most of the studies state the relation between shoulder pain/ injury and scapular dyskinesis 2,7,[9][10][11] .…”

BACKGROUND AND OBJECTIVES: Scapular dyskinesis has been associated to shoulder injuries and pain. However, this relationship with adolescent athletes is not well established. The objective of this study was to evaluate scapular dyskinesis in young athletes and its association with pain or shoulder function. METHODS: 178 male adolescent athletes (14.58±2.16 years) were evaluated. The subjects completed the Quick Disability Arm Shoulder Hand questionnaire. Body mass, height, shoulder internal rotation and Closed Kinetic Chain Upper Extremity Stability test were measured. A dynamic visual method was applied to assess dyskinesis. Binary logistic regression was applied to analyze the association between dyskinesis and other variables. The comparison between groups with and without dyskinesis was made by the Mann-Whitney and t-test, accepting a statistical significance of p<0.05. RESULTS: The dyskinesis prevalence was 56.7% and this condition was not associated with shoulder pain. Younger athletes are 159% more likely to have dyskinesis, while those who practice more than one hour a day for three times a week are 77% more likely to have the same outcome. No difference in shoulder function was found. CONCLUSION: Scapular dyskinesis is not associated with pain and does not affect shoulder function in adolescent athletes. Sports modality, age and training volume seem to induce changes in scapula movement. Keywords: Adolescents, Athletes, Athletic performance, Pain, Shoulder. Scapular dyskinesis was not associated with pain and function in male adolescent athletes RESUMO JUSTIFICATIVA E OBJETIVOS:A discinese escapular tem sido associada a lesões e dor no ombro, no entanto essa relação em adolescentes atletas ainda não é bem definida. O objetivo deste estudo foi avaliar a prevalência de discinese escapular em adolescentes atletas amadores e sua associação com a dor e medidas de função no ombro. MÉTODOS: 178 adolescentes do sexo masculino (14,58±2,16 anos) participaram do estudo. Os sujeitos responderam ao questionário Quick Disability Arm Shoulder Hand. Também foram avaliados massa corporal, estatura, rotação interna do ombro e Closed Kinetic Chain Upper Extremity Stability. Para avaliação da discinese escapular, utilizou-se o método visual dinâmico. A regressão logística binária foi utilizada para analisar a associação entre discinese e as demais variáveis. A comparação entre os grupos com e sem discinese foi feita pelo teste t e Mann-Whitney, sendo aceito significância estatística quando p<0,05. RESULTADOS: A prevalência de discinese foi de 56,7% e essa condição não teve associação com dor no ombro. Atletas mais jovens têm 159% mais chances de apresentar discinese, enquanto aqueles que treinam mais de uma hora por dia, durante três vezes por semana, têm 77% mais chances de ter o mesmo desfecho. Nenhuma diferença na função do ombro foi encontrada. CONCLUSÃO: A discinese escapular não está associada à dor e não altera medidas de função no ombro em adolescentes atletas.

“…observation during movement and maximal active humeral elevation, are relevant measures for therapists to use in clinical practice in IwS. Humeral motion can create early scapular motion by placing tension on a shortened glenohumeral capsule or stiff posterior-inferior glenohumeral muscles (Borich et al, 2006;Kibler et al, 2012;Laudner, Moline, & Meister, 2010). Hence, the increase in scapular lateral rotation and presence of anterior tilting and winging seen in IwS with moderate PAF compared to high PAF can be caused by restrictions in posterior glenohumeral structures.…”

“…Observation was done from a dorsal and lateral position. Presence of tilting or winging indicated a prominence of the inferior tip of the scapula dorsally or of the medial scapular border, respectively (Kibler, Sciascia, & Wilkes, 2012;Struyf et al, 2009). Palpation was used to verify anatomical landmarks.…”

Abstract. BACKGROUND:Clinical scapulohumeral tests are lacking post-stroke. OBJECTIVE: To test reliability and discriminant validity of clinical scapulohumeral assessments post-stroke. METHODS: Following tests were assessed in 57 individuals with stroke (IwS) (subdivided in a low, moderate, high proximal arm function (PAF) group) and 15 healthy controls: (1) Observation of tilting/winging; (2) shoulder girdle position tests (pectoralis minor index, acromial index, scapular distance test); (3) scapular lateral rotation measurement; (4) maximal humeral elevation and (5) medial rotation test were executed. 15 IwS were measured twice by the same assessor to determine test-retest reliability. Differences between controls and IwS and between IwS with different levels of PAF were assessed. RESULTS: ICCs were very high for all tests (>0.80), except the pectoralis minor index (0.66). Weighted Kappas were high for observation and the medial rotation test (>0.70). Group differences were found for observation, lateral rotation and humeral elevation. IwS compared to controls, and IwS with lower compared to higher PAF generally showed increased lateral rotation (p < .01); decreased maximal active humeral elevation (p < .001); and more often tilting and winging (p < .05). CONCLUSIONS: The use of these tests in clinical settings will allow for identification of altered scapular characteristics, which will enhance treatment planning for PAF post-stroke.

Scapular dyskinesis is detrimental to shoulder tendon properties and joint mechanics in a rat model

Shoulder tendon injuries are frequently seen in the presence of abnormal scapular motion, termed scapular dyskinesis. The cause and effect relationship between scapular dyskinesis and shoulder injury has not been directly defined. We developed and used an animal model to examine the initiation and progression of pathological changes in the rotator cuff and biceps tendon. Sixty male Sprague-Dawley rats were randomized into two groups: nerve transection (to induce scapular dyskinesis, SD) or sham nerve transection (control). The animals were euthanized 4 and 8 weeks after surgery. Shoulder function and passive joint mechanics were evaluated over time. Tendon mechanical, histological, organizational, and compositional properties were evaluated at both time points. Gross observation demonstrated alterations in scapular motion, consistent with scapular "winging." Shoulder function, passive internal range of motion, and tendon mechanical properties were significantly altered. Histology results, consistent with tendon pathology (rounded cell shape and increased cell density), were observed, and protein expression of collagen III and decorin was altered. This study presents a new model of scapular dyskinesis that can rigorously evaluate cause and effect relationships in a controlled manner. Our results identify scapular dyskinesis as a causative mechanical mechanism for shoulder tendon pathology. ß
