Differences in the Glenohumeral Joint before and after Unilateral Breast Cancer Surgery: Motion Capture Analysis.

After mastectomy, women might lose mobility and develop kinematic changes in the shoulder. The objective of this research was to compare the kinematics of the glenohumeral joint in women, before and after unilateral breast cancer surgery. This was a longitudinal study with a pre- and post-evaluation design; in total, 15 Mexican women who had a mastectomy for breast cancer and who received a physical therapy program after surgery were evaluated. Flexion-extension and abduction-adduction movements of the glenohumeral joint were evaluated (15 days before and 60 days after mastectomy). For the kinematic analysis of the glenohumeral joint, an optoelectronic motion capture system was used to monitor 41 reflective markers located in anatomical landmarks. There was no significant difference in the range of motion of the glenohumeral joint when comparing pre- and post-mastectomy, flexion-extension (p = 0.138), and abduction-adduction (p = 0.058). Furthermore, patients who received chemotherapy (53%) before mastectomy were more affected (lower range of motion) than those who did not receive it. There were no significant differences in the kinematics of the glenohumeral joint after mastectomy in this group of patients who received a physical therapy program after surgery. Moreover, patients who received chemotherapy treatment before breast cancer surgery tended to have a lower range of motion than those who did not receive it. Therefore, it is necessary for the physical rehabilitation team to attend to these patients even before the mastectomy.

Comparison of specific and non-specific treatment approaches for individuals with posterior capsule tightness and shoulder impingement symptoms: A randomized controlled trial.

BACKGROUND: Posterior capsule tightness (PCT) is associated with shoulder pain and altered shoulder kinematics, range of motion (ROM), external rotation (ER) strength, and pain sensitization. OBJECTIVE: To assess the effects of two interventions on shoulder kinematics, Shoulder Pain and Disability Index (SPADI) scores, ROM, strength, and pressure pain threshold (PPT) in individuals with PCT and shoulder impingement symptoms. METHODS: In this prospectively registered randomized controlled trial 59 individuals were randomized to either an Experimental Intervention Group (EIG, n=31) or a Control Intervention Group (CIG, n=28). The low flexion (LF) test was used to determine the presence of PCT. Shoulder kinematics, SPADI scores, internal rotation (IR) and ER ROM, ER strength, and PPT were measured pre- and post-treatment. Those in the EIG received an intervention specific to pain and PCT and those in the CIG received a non-specific intervention, both 4 weeks in duration. RESULTS: Individuals in the EIG demonstrated more scapular upward rotation (P=.03; mean difference (MD)=3.3°; 95% Confidence Interval (CI)=1.3°, 4.9°) and improved value on the LF test (P=.02; MD=4.6°; 95%CI=0.7°, 8.6°) than those in the CIG after treatment. Both groups presented less anterior (P<.01; MD=-0.7mm; 95%CI=-1.3mm, -0.2mm) and superior (P<.01; MD=-0.5mm; 95%CI=-0.9mm, -0.2mm) humeral translations, decreased SPADI score (P<.01; MD=-23.6; 95%CI=-28.7, -18.4), increased IR ROM (P<.01; MD=4.6°; 95%CI=1.8°, 7.8°) and PPTs for upper trapezius (P<.01; MD=60.1kPa; 95%CI=29.3kPa, 90.9kPa), infraspinatus (P=.04; MD=47.3kPa; 95%CI=2.1kPa, 92.5kPa), supraspinatus (P<.01; MD=63.7kPa; 95%CI=29.6kPa, 97.9kPa), and deltoid (P<.01; MD=40.9kPa; 95%CI=12.3kPa, 69.4kPa) after treatment. CONCLUSION: The experimental intervention was more effective at improving PCT as measured through changes in the LF test. No benefit of the specific approach over the non-specific intervention was noted for the remaining variables.

Different Shoulder Exercises Affect the Activation of Deltoid Portions in Resistance-Trained Individuals.

The aims of this study were to compare muscle activity of the anterior deltoid, medial deltoid, and posterior deltoid in the bench press, dumbbell fly, shoulder press, and lateral raise exercises. Thirteen men experienced in strength training volunteered for the study. Muscle activation was recorded during maximum isometric voluntary contraction (MVIC) for data normalization, and during one set of 12 repetitions with the load of 60% 1RM in all exercises proposed. One-way repeated-measures ANOVA with Bonferroni's posthoc was applied using a 5% significance level. For anterior deltoid, the shoulder press (33.3% MVIC) presented a significantly higher level of activation when compared to other exercises. Also, no significant difference was found between the bench press (21.4% MVIC), lateral raise (21.2% MVIC), and dumbbell fly (18.8% MVIC). For the medial deltoid, the lateral raise (30.3% MVIC) and shoulder press (27.9% MVIC) presented a significantly higher level of activity than the bench press (5% MVIC) and dumbbell fly (3.4% MVIC). Besides, no significant difference was found between the bench press and the dumbbell fly. For the posterior deltoid, the lateral raise (24% MVIC) presented a significantly higher level of activation when compared to other exercises. For the posterior deltoid portion, the shoulder press (11.4% MVIC) was significantly more active than the bench press (3.5% MVIC) and dumbbell fly (2.5% MVIC). Moreover, no significant difference was found between the bench press and the dumbbell fly. In conclusion, the shoulder press and lateral raise exercises showed a higher level of muscle activation in the anterior deltoid and medial deltoid when compared to the bench press and dumbbell fly exercises.

Radiographic evaluation of the glenohumeral joint space in patients undergoing arthroscopic shoulder surgery in the beach-chair position.

BACKGROUND: Shoulder arthroscopy can be performed with the patient in the lateral decubitus or beach-chair position, but in both cases, glenohumeral (GH) joint spaces must be increased to improve visualization and allow access of the optical instrument. The aim of this study was to determine the effects of limb setup and longitudinal traction on the opening of the GH space with patients placed in the beach-chair (dorsal decubitus) position. METHODS: GH spaces at 3 test points corresponding to the anatomic locations of Bankart lesions were determined indirectly from radiographic images obtained from 67 patients presenting shoulder pathology with an indication for arthroscopic surgery. Measurements were made with the operative limb in neutral rotation and positioned in relation to the coronal plane in adduction, 45° of abduction, or adduction with an axillary spacer, in each case with and without longitudinal traction. RESULTS: GH spaces were optimized at 2 of 3 test points when the operative limb was positioned in adduction or neutral rotation and manual longitudinal traction was applied with or without a polystyrene spacer placed under the axilla, but use of the spacer was essential to maximize the GH space at all 3 locations. In contrast, 45° of abduction proved to be the least appropriate position because it afforded the smallest GH space values with or without traction. CONCLUSION: Appropriate positioning of the patient on the operating table is a critical aspect of shoulder arthroscopy. Radiographic images revealed that adducted upper-limb traction with the use of an axillary spacer in patients in the beach-chair position generates a significant increase in the GH space in the lower half of the glenoid cavity, thereby facilitating visualization and access of the optical equipment to the GH compartments.

Shoulder external rotation range of motion and pectoralis minor length in individuals with and without shoulder pain.

Background: There is evidence that pectoralis minor (PM) length influences scapula position and that scapula position relates to glenohumeral joint (GHJ) external rotation (ER) range of motion (ROM). Objectives: To explore the association between PM resting length and GHJ ER ROM in individuals with and without shoulder pain. The influence of GHJ ER ROM measurement position on this association was also evaluated. Design: Cross-Sectional. Methods: Fifty individuals (25 asymptomatic and 25 with shoulder pain) participated. PM resting length was measured using a tape measure with subjects standing, while GHJ ER ROM was quantified using a digital inclinometer with participants in both supine and seated positions. The same blinded investigator took all measurements. Results/Findings: A significant negative correlation between PM resting length and GHJ ER ROM in the seated position was noted in the asymptomatic group (r = -0.41; p = 0.04), but not in the symptomatic group (r = -0.33; p = 0.11). A nonsignificant negative correlation was also demonstrated in the supine position for both groups (r ranged from -0.35 to -0.17; p > 0.05). There was a significant group x position interaction (F = 4.06; p = 0.04) with more GHJ ER ROM (6.80°) for asymptomatic group in the seated position. Conclusions: PM length is not strongly correlated with GHJ ER ROM in individuals with or without shoulder pain. However, the position in which GHJ ER ROM is measured influenced the motion in asymptomatic individuals.

Modified Bristow-Latarjet procedure for treatment of recurrent traumatic anterior glenohumeral dislocation.

OBJECTIVE: Retrospective case-control study of authors experience in the modified Bristow-Latarjet procedure for treatment of recurrent traumatic anterior glenohumeral dislocation with glenoid bone injury. METHODS: Sample with 102 recurrent glenohumeral dislocation cases submitted to modified Bristow-Latarjet procedure. Indications included situations of recurrent traumatic anterior glenohumeral instability with more than two dislocation episodes and with glenoid bone attritional or fragmentary injuries, without possibility of reconstruction. Mean follow-up time was 5.33 ± 2.74 years (minimum 1; range 1-13). RESULTS: The mean Walch-Duplay Score at the last evaluation was 91.23 ± 11.46 (range 15-100). The functional score of patients with glenoid bone loss greater than 20% did not show a significant difference in comparison with patients with glenoid bone loss lower than 20% (90 vs. 92, respectively). The functional score also did not show a significant difference between sports practice categories and between recreational and competitive practice, being excellent (greater than 90) in every category. There were no dislocation recurrences and the only complications were a case of persistent instability and a screw revision. Mild glenohumeral osteoarthrosis imaging signs were identified in 7.84% of the patients; however, their functional scores were not significantly different in comparison to other patients. CONCLUSION: The modified Bristow-Latarjet procedure is a very effective procedure with few complications in the medium-term, showing very satisfactory functional outcomes in the treatment of recurrent traumatic anterior glenohumeral dislocation associated with glenoid bone injury.

Change in the Distance From the Axillary Nerve to the Glenohumeral Joint With Shoulder External Rotation or Abduction Position.

BACKGROUND: This study investigated whether axillary nerve (AN) distance to the inferior border of the humeral head and inferior glenoid would change while placing the glenohumeral joint in different degrees of external rotation and abduction. METHODS: A standard deltopectoral approach was performed on 10 fresh-frozen cadaveric specimens. The distance between AN and the inferior border of the humeral head and inferior glenoid while placing the shoulder in 0°, 45°, and 90° of external rotation or abduction was measured. Continuous variables for changes in AN position were compared with paired 2-tailed Student t test. RESULTS: The mean distance between the AN and the humeral head with the shoulder in 0°, 45°, and 90° of external rotation and 0° of abduction was 13.77 mm (SD 4.31), 13.99 mm (SD 4.12), and 16.28 mm (SD 5.40), respectively. The mean distance between the AN and glenoid with the shoulder in 0°, 45°, and 90° of external rotation was 16.33 mm (SD 3.60), 15.60 mm (SD 4.19), and 16.43 (SD 5.35), respectively. The mean distance between the AN and the humeral head with the shoulder in 0°, 45°, and 90° of abduction and 0° of external rotation was 13.76 mm (SD 4.31), 10.68 mm (SD 4.19), and 3.81 mm (SD 3.08), respectively. The mean distance between the AN and glenoid with the shoulder in 0°, 45°, and 90° of abduction was 16.33 mm (SD 3.60), 17.66 mm (SD 5.80), and 12.44 mm (SD 5.57), respectively. CONCLUSIONS: The AN position relative to the inferior aspect of the glenohumeral joint does not significantly change despite position of external rotation. Increasing shoulder abduction over 45° decreases the distance from the glenohumeral joint to the AN and should be avoided.

The effect of intra-articular levobupivacaine on shoulder cartilage at different doses - experimental study / O efeito de levobupivacaína intra-articular na cartilagem do ombro em doses diferentes-estudo experimental

Abstract Background and objectives: In this study it was aimed to examine the histological and morphometric effects on cartilage structure of intra-articular application of levobupivacaine to the shoulder joint. Methods: In twenty New Zealand adult male rabbits, 35 shoulders were used for the study and prepared in 5 groups of 7. These groups were defined as Groups L1, L2, L3 and L4 which were right shoulders administered with 0.25% and 0.5% levobupivacaine, Group C which were left shoulders as the control group and Groups S1 and S2 which were left shoulders administered with 0.9% saline. On the 2nd and 15th days the animals were killed, the glenohumeral joints were evaluated macroscopically then cartilage samples were taken. These samples were evaluated with Mankin score, and histomorphometrically by measuring the thickness of the cartilage between the superficial cartilage layer and the tidemark and the thickness of calcified cartilage between the tidemark and the subchondral bone. Results: Macroscopically, on the 15th day the joint fluid was seen to have reduced in all the groups. After microscopic evaluation, the highest Mankin score (mean: 3.14 ± 2.1/14) was in the L4 group (15th day 0.5% levobupivacaine) and was found to be statistically significant (p < 0.05). No statistically significant difference was determined between the other groups. Conclusions: Histologically, as the highest Mankin score was in the L4 group, this indicates that in a single intra-articular injection of levobupivacaine a low concentration should be selected. Level of evidence: Level 5, animal study.

Resumo Justificativa e objetivo: Neste estudo o objetivo foi examinar os efeitos histológicos e morfométricos sobre a estrutura da cartilagem da aplicação intra-articular de levobupivacaína em articulação do ombro. Métodos: Trinta e cinco ombros de 20 coelhos New Zealand, machos e adultos, foram usados para o estudo e divididos em cinco grupos de sete. Os grupos foram definidos como L1, L2, L3 e L4, consistiram em ombros direitos nos quais levobupivacaína a 0,25% e 0,5% foi administrada; o Grupo C, que consistiu em ombros esquerdos, foi o grupo controle; os grupos S1 e S2, que consistiram em ombros esquerdos, receberam solução salina a 0,9%. Os animais foram sacrificados no segundo e no 15º dia; as articulações glenoumerais foram avaliadas macroscopicamente e, em seguida, amostras de cartilagem foram coletadas. As amostras foram avaliadas com o escore de Mankin e histomorfometricamente. Mediu-se a espessura da cartilagem entre a camada superficial e a "linha de maré" (tidemark) e a espessura da cartilagem calcificada entre a tidemark e o osso subcondral. Resultados: Macroscopicamente, observou-se no 15º dia que o líquido articular havia reduzido em todos os grupos. Após a avaliação microscópica, o maior escore de Mankin (média: 3,14 ± 2,1/14) foi observado no grupo L4 (15º dia levobupivacaína a 0,5%), considerado estatisticamente significativo (p < 0,05). Nenhuma diferença estatisticamente significativa foi determinada entre os outros grupos. Conclusões: Histologicamente, como o maior escore de Mankin foi observado no Grupo L4, isso indica que em uma única injeção intra-articular de levobupivacaína uma concentração baixa deve ser selecionada. Nível de evidência: Nível 5, estudo em animais.

Glenohumeral posterior mobilization versus conventional physiotherapy for primary adhesive capsulitis: a randomized clinical trial.

OBJECTIVE: To compare the short-term efficacy of a glenohumeral posterior mobilization technique versus conventional physiotherapy for the improvement of the range of external rotation in patients with primary adhesive capsulitis of the shoulder. METHODS: This is a randomized clinical trial conducted at Hospital Clinico San Borja Arriaran in Chile. Fifty-seven patients with an age range of 50 to 58 years old were enrolled in two groups. Both groups were randomized to receive a treatment of 10 sessions: the experimental group (n=29) received a glenohumeral posterior mobilization technique after training with a cycle ergometer, and the control group (n=28) received conventional physiotherapy. The primary outcome measure was range of passive movement in external rotation; secondary outcomes were forward flexion and shoulder abduction, pain perception using the visual analogue scale and functionality test using the Constant-Murley Score. RESULTS: The study had the statistical power to detect a difference of four degrees between the groups in the improvement of the range of external rotation at the end of the treatment period. The experimental group showed a significant improvement with a mean difference of 46.3 degrees (SD=8.7) compared to 18.1 (SD=7.2) in the control group (p<0.0001). There was also a decrease in the perception of pain (p= 0.0002) and improved function (p< 0.0001) in the group treated with glenohumeral posterior mobilization technique. CONCLUSIONS: The glenohumeral posterior mobilization technique applied after training with cycle ergometer is an effective short-term technique to treat primary adhesive capsulitis decreasing the severity of pain and improving joint function compared with conventional physiotherapy treatment. The degree of increase in shoulder external rotation is more than 20 degrees beyond the increase achieved with conventional treatment.

OBJETIVO: Demostrar la efectividad a corto plazo de la técnica de movilización posterior glenohumeral, en la mejoría del rango de rotación externa en pacientes con capsulitis adhesiva primaria de hombro. MÉTODOS: El presente estudio clínico aleatorizado, fue realizado en el Hospital Clínico San Borja Arriarán, donde 57 participantes en un rango de edad entre 50 y 58 años, fueron asignados de forma aleatoria a uno de dos grupos de tatamiento. A ambos grupos se les dio un tratamiento de 10 sesiones. El grupo experimental (n=29) recibió la técnica de movilización posterior glenohumeral luego de un entrenamiento con cicloergómetro. El grupo control (n=28) participó de un programa de tratamiento kinésico convencional. La medida de resultado primaria fue el rango de movimiento pasivo de rotación externa, las mediciones secundarias fueron el rango de flexión anterior y abducción, la percepción del dolor se midió con la escala visual analógica y la funcionalidad usando el puntaje de Constant-Murley. RESULTADOS: El estudio fue diseñado con potencia estadística para detectar una diferencia de cuatro grados en el rango de rotación externa entre los grupos al finalizar el tratamiento. El grupo experimental mostró una mejoría significativa con un promedio de la diferencia de 46,3 grados y desviación estándar 8,7 grados en comparación con el grupo control con 18,1 grados y desviación estándar 7,2 grados (p<0,0001). También hubo una disminución en la percepción del dolor (p=0,0002) y mejoró la funcionalidad (p<0,0001) en el grupo tratado con movilización posterior glenohumeral. CONCLUSIONES: La movilización posterior glenohumeral aplicada luego de un entrenamiento con cicloergómetro es una técnica efectiva a corto plazo en el manejo terapéutico de la capsulitis adhesiva primaria. Este tratamiento disminuye el dolor y mejora la función comparado con un tratamiento kinésico convencional. El grado de incremento en la rotación externa de hombro supera en más de 20 grados al tratamiento convencional.

Arthroscopic capsular release for refractory shoulder stiffness / Liberação capsular artroscópica para a rigidez refratária do ombro

OBJECTIVE: To evaluate the results of the arthroscopic treatment of refractory adhesive capsulitis of the shoulder with two to nine years of follow-up, comparing the pre-and postoperative range of motion. METHODS: This was an observational study (case series) of 18 patients who underwent arthroscopic capsular release for refractory shoulder stiffness. The mean age was of 53.6 years (range: 39 to 68), with female predominance (77.77%) and nine cases left shoulders. There were 6 primary (33.33%) and 12 secondary cases (66.67%). Arthroscopic capsular release was performed in all patients after a mean of 9.33 months of physical therapy (range: 6 to 20 months) with a minimum follow-up of two years (range: 26 to 110 months). RESULTS: The mean active and passive forward flexion, external rotation and internal rotation increased from 94.4º/103.3º, 11.9º/21.9º, and S1/L5 vertebral level, respectively, to 151.1º/153.8º, 57.2º/64.4º, and T12/T10 vertebral level, respectively. There was a significant difference between the pre-and postoperative range of motion (p < 0.001). according to the constant-murley functional score (rom), the value increased from 14 (preoperative mean) to 30 points (postoperative mean). postoperatively, all patients showed diminished shoulder pain (none or mild/15 or 10 points in the constant-murley score). CONCLUSION: arthroscopic treatment is an effective treatment for refractory shoulder stiffness.

OBJETIVO: Avaliar os resultados do tratamento artroscópico da capsulite adesiva refratária do ombro com dois a nove anos de seguimento, comparando o arco de movimentos pré e pós-operatório.

OBJECTIVE: To evaluate the results of the arthroscopic treatment of refractory adhesive capsulitis of the shoulder with two to nine years of follow-up, comparing the pre- and postoperative range of motion. METHODS: This was an observational study (case series) of 18 patients who underwent arthroscopic capsular release for refractory shoulder stiffness. The mean age was of 53.6 years (range: 39 to 68), with female predominance (77.77%) and nine cases left shoulders. There were 6 primary (33.33%) and 12 secondary cases (66.67%). Arthroscopic capsular release was performed in all patients after a mean of 9.33 months of physical therapy (range: 6 to 20 months) with a minimum follow-up of two years (range: 26 to 110 months). RESULTS: The mean active and passive forward flexion, external rotation and internal rotation increased from 94.4°/103.3°, 11.9°/21.9°, and S1/L5 vertebral level, respectively, to 151.1°/153.8°, 57.2°/64.4°, and T12/T10 vertebral level, respectively. There was a significant difference between the pre- and postoperative range of motion (p < 0.001). According to the Constant-Murley functional score (ROM), the value increased from 14 (preoperative mean) to 30 points (postoperative mean). Postoperatively, all patients showed diminished shoulder pain (none or mild/15 or 10 points in the Constant-Murley score). CONCLUSION: Arthroscopic treatment is an effective treatment for refractory shoulder stiffness.

Artroplastia do ombro na osteoartrose: correlação entre função e parâmetros radiográficos / Shoulder arthroplasty in osteoarthritis: correlation between function and radiographic parameters

Objetivos: Avaliar a correlação entre os parâmetros radiográficos e as avaliações funcionais de pacientes com osteoartrose do ombro submetidos à artroplastia do ombro e descrever os resultados funcionais deste procedimento em nosso serviço. Métodos: Foram avaliados 21 pacientes (22 ombros) que realizaram artroplastias do ombro entre 1998 e 2010 e que apresentassem tempo mínimo de seguimento de 12 meses. A avaliação clínica foi realizada através das escalas de Constant-Murley, UCLA, EVA e da medida do arco de movimento ativo. Aferimos parâmetros radiográficos pré-operatórios (distância entre o topo da cabeça e o úmero e o acrômio, migração superior, inclinação do colo,“offset” medial, subluxação do úmero, erosão da glenóide) e pós-operatórios (inclinação da haste, migração dos componentes e sinais de soltura). Resultados: Os pacientes apresentaram melhora significativa em todos os parâmetros avaliados: flexão (p=0,0083), abdução (p=0,0266), rotação externa (p=0,0062), Constant-Murley (p=0,0001), UCLA (p<0,0001) e EVA (p=0,0002). A migração superior do úmero e as escalas de UCLA e de Constant-Murley apresentaram uma correlação significativa (p=0,0480 e p=0,0110, respectivamente). Os demais parâmetros radiográficos não demonstraram correlação com os resultados clínicos. Conclusão: a migração superior do úmero está relacionada a uma piora dos indicadores funcionais. Nível de Evidência IV, Série de Casos.

Objectives: To evaluate the correlation between radiographic parameters and functional assessments of patients with osteoarthritis of the shoulder who underwent shoulder arthroplasty and describe the functional outcomes of this procedure in our institution. Methods: we evaluated 21 patients (22 shoulders) who underwent shoulder arthroplasty between 1998 and 2010 with a minimum follow-up of 12 months. Clinical evaluation was performed using the Constant-Murley scale, UCLA, VAS and measuring the arc of active motion. We analysed preoperative radiographic parameters (distance from the top of the head and the humerus and the acromion, superior migration, neck angulation, medial “offset”, subluxation, glenoid cavity erosion) and postoperatively we evaluated rod inclination, migration of components and loosening. Results: patients showed significant improvement in all parameters: flexion (p = 0.0083), abduction (p = 0.0266), external rotation (p = 0.0062), Constant-Murley (p = 0.0001 ), UCLA (p < 0.0001) and VAS (p = 0.0002). The superior migration of the humerus showed a significant correlation with UCLA and Constant-Murley scores (p = 0.0480 and p = 0.0110, respectively). The other radiographic parameters had no correlation with the clinical outcomes. Conclusion: the superior migration of the humerus is related to a worsening of clinical scores. Level of Evidence IV, Case Series.

Associação entre discinesia escapular e dor no ombro de praticantes de natação / Association between scapular dyskinesia and shoulder pain in swimmers

A escápula possui funções essenciais no ombro do atleta de arremesso. Qualquer desequilíbrio presente entre as estruturas responsáveis pela sua estabilidade originará uma condição denominada discinesia escapular, a qual é comumente acompanhada de dor no ombro. Este estudo tem o objetivo de verificar se há associação entre a discinesia escapular e a dor no ombro de praticantes de natação. Foi realizado um estudo analítico observacional de corte transversal, incluindo 36 praticantes de natação do sexo masculino, com idade de 18 a 36 anos. Como métodos diagnósticos sugestivos de discinesia escapular foram utilizados o Slide Lateral Scapular Test e a filmagem proposta por Kibler. A existência de proporções significativas entre as variáveis nominais foi comprovada pelo teste do qui-quadrado ou pelo teste exato de Fisher. Para identificar associações entre as variáveis contínuas e os grupos de estudo foi utilizado o teste t de Student. Um p < 0,05 foi considerado estatisticamente significante. O grau de concordância interexaminador (Kappa; p < 0,0001) foi considerado substancial, correspondendo a 86,1 por cento (0,7656) no ombro direito e 83,3 por cento (0,6412) no esquerdo. Constatou-se que a grande maioria (80 por cento) dos indivíduos que apresentaram positividade no Slide Lateral Scapular Test relatou dor no ombro. Dentre os nadadores que apresentaram discinesia escapular durante a filmagem, em 70,8 por cento também foi constatada a presença dessa condição no teste estático. Este é um estudo original no que diz respeito à abordagem da discinesia escapular em nadadores e em relacioná-la com a presença de dor no ombro. Porém, a hipótese inicial de que haveria uma associação significante não foi correspondida.

The scapula plays an essential role in the throwing motion performed by athletes. Scapular dyskinesia is a condition characterized by imbalance in the structures responsible for the joint stability, which is often accompanied by shoulder pain. The main objective of this study is to assess the relationship between scapular dyskinesia and shoulder pain in swimmers. A total of 36 male swimmers aged between 18 and 36 years were diagnosed for scapular dyskinesia utilizing two different methods: the Lateral Slide Scapular Test and the video recording method suggested by Kibler. Statistical analysis was performed using the Chi-square test or Fisher's exact test. Comparisons between groups were performed using the t-test. The degree of p< 0.05 was considered statistically significant. Significance was set at á=0.05. There was a high inter-rate reliability concerning the video analysis (Kappa; p<0.0001), corresponding to 86.1 percent (0.7656) on the right shoulder and 83.3 percent (0.6412) on the left shoulder. The majority of the individuals that had positive diagnosis assessed by the Lateral Slide Scapular Test (80 percent) reported pain on the shoulder. Furthermore, 70.8 percent of the subjects who had positive diagnosis by the video recording also had positive diagnosis in the static test. Although a significant association between scapular dyskinesia and shoulder pain was not found, this is an important study to approach these conditions in swimmers.
