RESUMO

INTRODUCTION: Despite being the most used exam today, few studies have evaluated the accuracy of findings on non-contrast magnetic resonance imaging (MRI). The primary objective of the study was to evaluate the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of non-contrast MRI findings in frozen shoulder, isolated and in combination. The secondary objectives were to define the interobserver and intraobserver agreement of the assessments and the odds ratio for frozen shoulder because of the various findings of MRI. METHODS: A retrospective diagnostic accuracy study comparing non-contrast MRI findings between the frozen shoulder group and the control group. Sensitivity, specificity, positive and negative predictive value, accuracy, odds ratio, interobserver and intraobserver agreement were calculated for each finding and their possible associations. RESULTS: The hyperintensity on capsule in the axillary recess presented 84% sensitivity, 94% specificity, and 89% accuracy. The obliteration of the subcoracoid fat triangle in the rotator interval had sensitivity 34%, specificity 82% and accuracy 58%. For coracohumeral ligament thickness ≥ 2 mm had specificity 66%, 48% specificity and 57% accuracy. Capsule thickness in the axillary recess ≥ 4 mm resulted in 54% sensitivity, 82% specificity, and 68% accuracy. Regarding interobserver agreement, only the posteroinferior and posterosuperior quadrants showed moderate results, and all the others showed strong reliability. The odds ratio for hyperintensity in the axillary recess was 82.3 for frozen shoulder. The association of these findings increased specificity (95%). CONCLUSION: The accuracy of non-contrast magnetic resonance imaging is high for diagnosing frozen shoulder, especially when evaluating the hyperintensity of the axillary recess. The exam has high reliability and reproducibility. The presence of an association of signs increases the specificity of the test. LEVEL OF EVIDENCE: Level III, study of diagnostic test.

RESUMO

OBJECTIVE: To compare the efficacy of rotator interval (RI) vs posterior approach (PA) ultrasound (US) guided corticosteroid injections into the glenohumeral (GH) joint in primary frozen shoulder (PFS). DATA SOURCES: A systematic literature search for all relevant studies on Medline, Scopus, Embase, Web of Science, and Cochrane Central, up to January 2023 was conducted. STUDY SELECTION: Randomized controlled trials that directly compared the US-guided corticosteroid injection into the RI and GH joint using PA in patients clinically and radiographically diagnosed with PFS. DATA EXTRACTION: The primary outcome was pain, and the secondary outcomes were function, and range of motion (ROM). Two authors independently assessed the risk of bias using the Cochrane risk-of-bias tool version 2. A random-effects model and generic inverse variance method were performed. Effect sizes were estimated using mean difference (MD) and standardized mean difference (SMD). DATA SYNTHESIS: A total of 5 clinical trials involving 323 subjects were included for the meta-analysis. US-guided corticosteroid injections into the RI revealed significant pain relief (MD 1.33 [95% confidence interval (CI) 0.20 to 2.46]; P=.02) and significant functional improvement (SMD 1.31 [95% CI 0.11 to 2.51]; P=.03) compared with the PA after 12 weeks. CONCLUSION: The results suggest the injection of corticosteroid into RI space is more effective than PA after 12 weeks in improving both pain and functional scores in patients with PFS.

RESUMO

Abstract Objective The advent of the Internet has provided new, easily accessible resources for patients seeking additional health information. Many doctors and healthcare organizations post informative videos on this platform, and nearly all patients are looking for videos online for a second opinion. Methods The phrases "frozen shoulder," "frozen shoulder treatment," "adhesive" capsulitis, and "adhesive capsulitis treatment" were entered into YouTube's search bar for a normal inquiry. The informativeness and overall quality of the adhesive capsulitis videos were rated using three separate scales. Results The mean and standard deviation values of the scoring systems were JAMA 1.25 ± 0.51, DISCERN 39.4 ± 13.4, GQS 2.83 ± 0.96 and ACSS 7.43 ± 4.86, respectively. Number of views, rate of views, and likes all had a positive correlation with Global Quality Score (GQS), as did DISCERN and ACSS. There was no statistically significant difference between the median JAMA, GQS score and Discern Criteria values according to the video source/uploader (p > 0.05). Conclusion YouTube videos on adhesive capsulitis, thus, need to be of higher quality, reliability, and instructive quality. There is a need for reliable videos about adhesive capsulitis, with instructional and high-quality cited.

RESUMO

The purpose of this study is to evaluate the effects of high-intensity laser therapy (HILT) in patients with frozen shoulder. PRISMA guidelines were adhered to, and a systematic search was conducted in the PubMed, Web of Science, Scopus, CINAHL, Science Direct, and PEDro databases (last update: September 4, 2023; search period: December 2022-September 2023). The inclusion criteria encompassed RCTs comparing HILT with other physical therapy interventions in frozen patients with frozen shoulders, with or without sham HILT, assessing pain intensity, shoulder ROM, and disability outcomes. The quality of the RCTs was assessed with the Cochrane Risk of Bias tool, and evidence was assessed using the GRADE approach. Five trials met the eligibility criteria and were included in the review and meta-analysis, which pooled results from the visual analog scale (VAS), goniometry, and the shoulder pain and disability index (SPADI). Mean differences (MDs) for pain intensity and disability show a pooled effect in favor of HILT both for VAS (MD = - 2.23 cm, 95% CI: - 3.25, - 1.22) and SPADI (MD = - 10.1% (95% CI = - 16.5, - 3.7), changes that are statistical (p < 0.01) and clinical. The MD for flexion (MD = 9.0°; 95% CI: - 2.36°, 20.3°; p = 0.12), abduction (MD = 3.4°; 95% CI: - 6.9°, 13.7°; p = 0.51), and external rotation (MD = - 0.95°; 95% CI: - 5.36°, 3.5°; p = 0.67) does not show statistical and clinical differences between groups after treatment. PI and disability changes were graded as important due to their clinical and statistical results. HILT into a physical therapy plan reduce pain and disability, but it does not outperform conventional physical therapy in improving shoulder ROM. It is suggested that future RCTs compare the effects of HILT and LLLT to assess their possible differences in their analgesic effects.

RESUMO

BACKGROUND: Contradictory evidence exists regarding the clinical course of frozen shoulder (FS). OBJECTIVES: To explore the clinical course of FS regarding disabilities, pain, range of motion (ROM), muscle strength, scapular upward rotation, and proprioception and to establish longitudinal correlations between these variables. METHODS: Patients with FS were prospectively followed for 9 months at 3-month intervals. Assessment included the Disabilities of the Arm, Shoulder and Hand questionnaire; visual analogue scale for pain; an inclinometer for shoulder external rotation (ER), internal rotation (IR), flexion, and abduction ROM, and scapular upward rotation and proprioception, as well as handheld dynamometry for muscle strength in shoulder abduction, ER, and IR. RESULTS: Initially, 149 patients (98 females; mean (SD) age 53 (9) years) were included, with 88 completing all follow-up assessments. Most variables showed early improvement in the clinical course of FS, particularly ER and IR at 90° abduction, which continued to improve from 6 to 9 months of follow-up. Associations were observed between disabilities and pain (r = 0.61), disabilities/pain and ROM (r=-0.62 to -0.59 and r=-0.47 to -0.39, respectively), disabilities/pain and muscle strength (r=-0.24 to -0.35 and r=-0.36 to -0.17, respectively), and between disabilities/pain and scapular upward rotation below shoulder level (r = 0.23 to 0.38 and r = 0.24 to 0.30, respectively). ROM correlated with muscle strength (r = 0.14 to 0.44), while both ROM and ER muscle strength correlated with scapular upward rotation below shoulder level (r=-0.37 to -0.23 and r=-0.17 to -0.12, respectively). Muscle strength correlated with scapular upward rotation above shoulder level (r = 0.28 to 0.38) and lift-off muscle strength correlated with joint repositioning (r=-0.17 to -0.15). CONCLUSION: Almost all factors improved in the early phase (3-6 months) after baseline assessment, while ER and IR ROM at shoulder level continued to improve long term.

RESUMO

Objective To evaluate the functionality in patients with adhesive capsulitis undergoing suprascapular nerve block (SSNB). Methods A before-and-after clinical prospective study in a single center was conducted with patients with secondary adhesive capsulitis treated with four nerve blocks based on anatomical limits. The sample was non-probabilistic, and it was obtained after a routine appointment at a specialized outpatient clinic. The instruments used for evaluation were the International Classification of Functioning, Disability and Health (ICF) and the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, which were applied at baseline (T 0 ), one week after the fourth SSNB (T 4 ), and three months after the first SSNB (T 12 ). The paired t -test was used to compare the means of the ICF checklist items and DASH in the different: T 0 xT 4 ; T 4 xT 12 ; and T 0 xT 12 ). The probability of rejecting the null hypothesis was 5%. Results The sample was composed of 25 individuals with a mean age of 58.16 years; 16 of them were female. The duration of the pain symptoms ranged from 2 to 16 months, with a mean of 5.92 months. The ICF checklist showed that all domains had already improved in T 4, except for the environmental factors, which only improved at 03 months ( p = 0.037). The patients reported improvements in shoulder function in T 4 , which increased more in T 12 , at the end of data collection ( p = 0.019). Conclusion The SSNB technique is effective in patients with adhesive capsulitis after 4 weeks of application, with improvements in individual's functionality lasting for 12 weeks.

RESUMO

Objective The present study aimed to assess the association between anxiety and depression symptoms in patients with adhesive capsulitis. Methods This was a cross-sectional study carried out in a single center from a tertiary hospital with patients presenting with secondary adhesive capsulitis. The control group did not have shoulder disease, thyroid disease, anxiety, and/or depression. The instrument used was the Hospital Anxiety and Depression Scale (HADS). An analysis of covariance compared HADS scores between groups. The significance level was 5%. Results The final sample consisted of 17 patients (case group) and 27 (control group). The Shapiro-Wilk test revealed normal distribution ( p > 0.05). A HADS score > 0.70 (Cronbach alpha) was reliable and presented good internal consistency. Patients with adhesive capsulitis reported "doubtful" (average/standard deviation = 8.88/4.50) "anxious symptoms" ( p = 0.019) but no "depressive symptoms" (average/standard deviation = 6.41/3.69), despite p = 0.015. Conclusion There is a "doubtful" positive association between anxiety symptoms and adhesive capsulitis but a negative association with depressive symptoms.

RESUMO

Abstract Objective Adhesive capsulitis is a condition characterized by shoulder pain and stiffness. Breast cancer treatment has been linked to the development of this condition, but its mechanisms are still little known. This study's objective was to identify predictors factors associated with the development of adhesive capsulitis in breast cancer patients. Methods A case control study was performed with women undergoing treatment for breast cancer in a single center. The sampling was nonprobabilistic and consecutive. Adhesive capsulitis was defined as constant pain associated with decreased active and passive shoulder movement in anterior elevation, external rotation at 0°/90° abduction, and internal rotation at 90° abduction. The study group consisted of patients with shoulder pain and range of motion limitations, while the control group consisted of women without any shoulder abnormalities. Sociodemographic and clinical variables were collected. A univariate logistic regression was used to assess the influence of variables on the studied outcome. For p< 0.20, a multivariate logistic regression was used. The probability of null hypothesis rejection was 5%. Results A total of 145 women were assessed, with 39 (26.9%) on the study group and 106 (73.1%) on the control group. The majority was under 60 years old. In the multivariate analysis, variables correlated to the outcome under study were shoulder immobilization (OR = 3.09; 95% CI: 1.33-7.18; p= 0.009), lymphedema (OR = 5.09; 95% CI: 1.81-14.35; p= 0.002), and obesity (OR = 3.91; 95% CI: 1.27-12.01; p= 0.017). Conclusion Lymphedema, postsurgery immobilization, and obesity are predictive factors for the development of adhesive capsulitis in breast cancer patients.

RESUMO

INTRODUCTION: the management of adhesive capsulitis (AC) remains a topic of debate among orthopedic surgeons, with a wide variation in the literature. Conservative treatment relies as the first-line option as clinical studies report positive outcomes. However, there is variability in the effectiveness of different treatment modalities. MATERIAL AND METHODS: this study aimed to analyzed functional and clinical outcomes of patients with AC who underwent the arthrodilation protocol, including three ultrasound-guided injections administered on a weekly basis: two corticosteroid injections and one injection of hyaluronic acid combined with corticosteroids. Additionally, patients received a specific rehabilitation therapy. Visual analogue scale (VAS), the university of California-Los Angeles shoulder score (UCLA) and Constant-Murley score were assessed before treatment and after 3-month follow-up period. RESULTS: 23 patients were included, receiving the same treatment protocol with a mean onset of symptoms of 4.9 ± 1.7 months. Among these patients, there was a clear predominance of females (65.2%). Age distribution ranged from 39 to 74 years (mean = 56) indicating that individuals in their mid-50s were more susceptible to developing this condition. Furthermore, a slight majority (52.2%) exhibited AC in their right shoulder. VAS significantly decreased (-6.09 ± 1.9 [p 0.05]). Similarly, UCLA score (10.9 ± 2.9 to 31.7 ± 2.2) and Constant-Murley score (22.3 ± 6.1 to 62.0 ± 6.2) improved significantly. Pre-to-post treatment evaluation showed improvement in both UCLA (mean = 20.8 ± 2.9 [p 0.05]) and Constant-Murley (mean = 39.7 ± 9 [p 0.05]). CONCLUSION: arthrodilation protocol demonstrated promising results, with patients achieving good to excellent outcomes and safely resuming their regular daily activities within a short-term follow-up period. These findings provide support for arthrodilation as a viable conservative management option and contribute valuable insights to the ongoing research aimed at identifying optimal treatment approaches for adhesive capsulitis.

INTRODUCCIÓN: el tratamiento de la capsulitis adhesiva (CA) sigue siendo un tema de debate entre los cirujanos ortopedistas, con una variación amplia en la literatura. El tratamiento conservador se considera la opción de primera línea, ya que los estudios clínicos muestran resultados positivos. Sin embargo, existe variabilidad en la efectividad de las diferentes modalidades de tratamiento. MATERIAL Y MÉTODOS: este estudio tuvo como objetivo analizar los resultados funcionales y clínicos de pacientes con CA que se sometieron al protocolo de artrodilatación, incluyendo tres inyecciones guiadas por ultrasonido administradas semanalmente: dos inyecciones de corticosteroides y una inyección de ácido hialurónico combinado con corticosteroides. Además, los pacientes recibieron una terapia de rehabilitación específica. La escala analógica visual (EVA), la puntuación del hombro de la Universidad de California-Los Ángeles (UCLA) y la puntuación de Constant-Murley se evaluaron antes del tratamiento y después de un período de seguimiento de tres meses. RESULTADOS: se incluyeron 23 pacientes que recibieron el mismo protocolo de tratamiento con un inicio medio de síntomas de 4.9 ± 1.7 meses. Entre estos pacientes hubo un claro predominio del sexo femenino (65.2%). La distribución por edades osciló entre 39 y 74 años (media = 56), lo que indica que las personas de alrededor de 55 años eran más susceptibles a desarrollar esta afección. Además, una ligera mayoría (52.2%) presentaba CA en el hombro derecho. La EVA disminuyó significativamente (-6.09 ± 1.9 [p 0.05]). De manera similar, la puntuación de UCLA (10.9 ± 2.9 a 31.7 ± 2.2) y la puntuación de Constant-Murley (22.3 ± 6.1 a 62.0 ± 6.2) mejoraron significativamente. La evaluación previa y posterior al tratamiento mostró una mejoría tanto en UCLA (media = 20.8 ± 2.9 [p 0.05]) como en Constant-Murley (media = 39.7 ± 9 [p 0.05]). CONCLUSIÓN: el protocolo de artrodilatación demostró resultados prometedores, los pacientes lograron resultados de buenos a excelentes y reanudaron de manera segura sus actividades diarias regulares dentro de un período de seguimiento a corto plazo. Estos hallazgos respaldan la artrodilatación como una opción de tratamiento conservador viable y aportan conocimientos valiosos a la continua investigación destinada a identificar tratamientos óptimos para la capsulitis adhesiva.

RESUMO

RESUMEN El hombro se considera la articulación más móvil e inestable del cuerpo humano. La capsulitis adhesiva es una patología frecuente en el hombro, es de causa desconocida, curso variable, y de tratamiento controversial, frecuentemente asociada a diabetes mellitus. La rehabilitación de la misma, tradicionalmente ha correspondido a ejercicios con peso y movimientos pendulares. La kinesioterapia propioceptiva es pilar fundamental durante la rehabilitación de esta patología. El objetivo de la investigación es demostrar la influencia de los ejercicios físico-propioceptivos en el alivio del dolor y la recuperación de la fuerza muscular, en pacientes con capsulitis adhesiva. Se realizó un estudio experimental de corte explicativo, longitudinal, cualitativo-cuantitativo con grupo control, en una población de 30 pacientes que recibieron tratamiento rehabilitador de hombro, en el Instituto de Medicina Deportiva de La Habana, Cuba, durante tres meses consecutivos, en el período comprendido entre enero y diciembre de 2017. A ambos grupos, se les realizó evaluación clínica, historia clínica y aplicación de la Escala de Constant antes y después del tratamiento. Los pacientes del Grupo Experimental realizaron un sistema de ejercicios propioceptivos y los pacientes del Grupo Control realizaron ejercicios pendulares. El alivio del dolor se alcanzó durante el primer mes de tratamiento en el grupo experimental, pues presentó mejores resultados en la recuperación de la fuerza muscular que el Grupo Control entre el segundo y tercer mes de tratamiento (p=1,000). En conclusión, los ejercicios propioceptivos permiten, en poco tiempo, aliviar el dolor de hombro, así como recuperar la fuerza muscular en pacientes con capsulitis adhesiva.

RESUMO O ombro é considerado a articulação mais móvel e instável do corpo humano. A capsulite adesiva é uma patologia comum do ombro, de causa desconhecida, curso variável e tratamento controverso, frequentemente associada ao diabetes mellitus. A reabilitação tem envolvido tradicionalmente exercícios de peso e movimentos pendulares. A Kinesioterapia proprioceptiva é um pilar fundamental durante a reabilitação desta patologia. O objetivo da pesquisa é demonstrar a influência dos exercícios físicos-proprioceptivos no alívio da dor e na recuperação da força muscular em pacientes com capsulite adesiva. Foi realizado um estudo experimental explicativo, longitudinal, qualitativo-quantitativo com um grupo de controle em uma população de 30 pacientes que receberam tratamento de reabilitação do ombro no Instituto de Medicina Esportiva em Havana, Cuba, durante três meses consecutivos, no período de janeiro a dezembro de 2017. Ambos os grupos foram submetidos a avaliação clínica, histórico clínico e aplicação da Escala Constante antes e depois do tratamento. Os pacientes do Grupo Experimental realizaram um sistema de exercícios proprioceptivos e os pacientes do Grupo de Controle realizaram exercícios de pêndulo. O alívio da dor foi alcançado durante o primeiro mês de tratamento no Grupo Experimental, que mostrou melhores resultados na recuperação da força muscular do que no Grupo de Controle entre o segundo e terceiro mês de tratamento (p=1.000). Em conclusão, os exercícios proprioceptivos permitem, em pouco tempo, aliviar a dor no ombro, assim como recuperar a força muscular em pacientes com capsulite adesiva.

ABSTRACT The shoulder is considered the most mobile and unstable joint of the human body. Adhesive capsulitis is a common pathology in the shoulder, with unknown cause, variable course, and controversial treatment, often associated with diabetes mellitus. The rehabilitation of the same traditionally has corresponded to weight-bearing exercises and pendulum movements. Proprioceptive kinesiotherapy is a fundamental pillar during the rehabilitation of this pathology. The objective of this research is to demonstrate the influence of physical proprioceptive exercises in pain relief and muscle strength recovery in patients with adhesive capsulitis. An experimental study of explanatory cut, longitudinal, qualitative-quantitative with control group, in a population of 30 patients who received rehabilitative treatment of shoulder, in the Institute of Sports Medicine of Havana, Cuba, during three consecutive months, in the period between January and December 2017 was carried out. Both groups underwent clinical evaluation, clinical history and application of the Constant Scale before and after treatment. Patients in the Experimental Group performed a proprioceptive exercise system and patients in the Control Group performed pendulum exercises. Pain relief was achieved during the first month of treatment in the experimental group, since it presented better results in the recovery of muscle strength than the Control Group between the second and third month of treatment (p=1.000). In conclusion, proprioceptive exercises allow, in a short time, to relieve shoulder pain, as well as to recover muscle strength in patients with adhesive capsulitis.

RESUMO

A capsulite adesiva é uma condição dolorosa comum e debilitante da articulação glenohumeral que afeta cerca de 2 a 5% da população. Os órgãos internos e o sistema musculoesquelético são interligados por meio das membranas de sustentação. A tensão nessas membranas pode causar ainda mais restrições mecânicas, dor nas estruturas musculoesqueléticas e também restringir a mobilidade de órgãos viscerais. OBJETIVO: Explorar o efeito da manipulação visceral específica de órgãos na capsulite adesiva em pessoas afetadas no ombro direito. METODOLOGIA: Vinte indivíduos com capsulite adesiva foram avaliados para elegibilidade, dos quais 14 foram recrutados usando o método de amostragem por conveniência. Duas sessões de manipulação visceral comparada com manipulação placebo foram administradas nas primeiras duas semanas, seguidas de duas sessões de manipulação visceral do fígado nas duas semanas seguintes. O goniômetro digital, o nível de dor, a incapacidade no ombro e o esfigmomanômetro modificado foram usados para medir os resultados pré e pós intervenção. RESULTADOS: A comparação dos resultados entre os grupos mostrou uma diferença estatisticamente significativa nos escores de amplitude de movimentos [flexão (p = 0,001), rotação externa (p = 0,001), rotação interna (p = 0,001)], dor no ombro e escore do índice de incapacidade (0,004). Nenhuma mudança significativa foi observada no resultado de força. CONCLUSÃO: Duas sessões de manipulação visceral para o fígado podem ser benéficas na melhora da mobilidade do ombro direito, dor e incapacidade.

Adhesive capsulitis is a common, painful and debilitating condition of the glenohumeral joint affecting about 2-5% of the population. Internal organs and musculoskeletal system are inter-connected through the support membranes. Tension in these support membranes may further cause mechanical restrictions and pain in musculoskeletal structures and also restrict the mobility of the visceral organ. OBJECTIVE: To explore the effect of organ specific visceral manipulation on adhesive capsulitis in subjects with right shoulder adhesive capsulitis. METHODOLOGY: Twenty subjects with adhesive capsulitis were assessed for eligibility, out of which fourteen subjects were recruited using convenience sampling method. Two sessions of Placebo Visceral Manipulation was administered for the first two weeks, followed by a two sessions of visceral manipulation of liver for next two weeks. Digital goniometer, Shoulder pain and disability index and Modified sphygmomanometer were used to measure the pre and post outcomes. RESULTS: Between group comparison of the outcomes showed a statistically significant difference in the shoulder range of motions scores [flexion (p=0.001), external rotation (p=0.001) and internal rotation (p=0.001)] and Shoulder pain and disability index score (0.004). No significant changes were observed in the strength outcome. CONCLUSION: Two sessions of visceral manipulation for the liver may be beneficial in improving the right shoulder mobility, pain and disability

RESUMO

Objective To clarify the association of thyroid disorders and primary frozen shoulder by comparing this group with controls without shoulder disease and with patients with rotator cuff tears. Methods We evaluated 166 patients who presented frozen shoulder with treatment in progress or already treated, which were compared with 129 patients with diagnosis of rotator cuff tears and 251 control subjects. All of the participants answered the questionnaire on the following variables: age, gender, body mass index (BMI), occupation, physical activity, presence of thyroid disorders and other comorbidities, smoking and use of alcohol. Results When comparing the frozen shoulder group with the control and rotator cuff groups, there is a specific association between the presence of thyroid disorders and frozen shoulder. By calculating relative risk, it is possible to state that an individual with thyropathy has 2.69 more chance of developing frozen shoulder. Also, there was an association with gender, since women with frozen shoulder exceeded significantly the risk. Conclusions Thyroid disorders, especially hypothyroidism and the presence of benign thyroid nodules, are risk factors significantly associated with frozen shoulder, rising the chances to 2.69 times of developing frozen shoulder. This is the first study that uses, in addition to the control group, a second group with rotator cuff tears, so it was shown that there is a specific association of thyroid disorders and frozen shoulder, but not with shoulder disorders in general.

Resumo Objetivo Verificar a asssociação entre tireopatias e ombro congelado primário, comparando com grupo controle e com grupo de pacientes com lesão no manguito rotador. Métodos Foram avaliados 166 pacientes com diagnóstico de ombro congelado primário com tratamento em andamento ou já tratados. Este grupo foi comparado com 129 pacientes com diagnóstico de lesão de manguito rotador e com um terceiro grupo controle formado por 251 indivíduos sem acometimento dos ombros. Todos os participantes responderam questionário sobre as seguintes variáveis: idade, gênero, índice de massa corpórea (IMC), profissão, atividade física, presença de tireopatia e de outras comorbidades, hábito tabagista e etilismo. Resultados Quando comparamos o grupo de ombro congelado com os grupos controle e lesão de manguito rotador, percebemos que existe uma associação específica entre presença de doenças da tireoide (tireoidite, hipotireoidismo, hipertireoidismo, nódulos e câncer) e ombro congelado. Através do cálculo do risco relativo, é possível afirmar que um indivíduo com tireopatia tem probabilidade 2.69 maior de desenvolver ombro congelado. Também houve associação com gênero, já que as mulheres com ombro congelado elevam significativamente esse risco. Conclusão Os distúrbios da tireoide, especialmente o hipotireoidismo e a presença de nódulos tireoidianos benignos, são fatores de risco significativamente associados ao ombro congelado, aumentando as chances em 2,69 vezes de desenvolver a doença. Este é o primeiro estudo que utiliza, além do grupo controle, um segundo grupo com lesões do manguito rotador, de modo que foi demonstrada uma associação específica de distúrbios da tireoide e ombro congelado.

RESUMO

OBJECTIVE: To correlate the thickness of the axillary recess capsule measured by ultrasound with magnetic resonance imaging signs of adhesive capsulitis in patients with shoulder pain. MATERIALS AND METHODS: We prospectively evaluated 193 consecutive patients (141 women and 52 men, aged 40-69 years) with shoulder pain lasting 1-9 months from January 2015 to December 2016 who underwent shoulder ultrasound. All participants had routine shoulder ultrasound with additional measurement of axillary recess capsule thickness. After examinations, two groups were formed: negative ultrasound group, composed of patients with a capsule thickness of 2.0 mm or less, and positive ultrasound group, composed of individuals with a capsule thickness greater than 2.0 mm. All patients from the positive ultrasound group and 27 randomly chosen patients from the negative ultrasound group underwent shoulder magnetic resonance imaging. RESULTS: In all, 169/193 patients (88%) had an axillary recess capsule thickness of 2.0 mm or less (negative ultrasound group) and 24/193 patients (12%) had a capsule thickness greater than 2.0 mm (positive ultrasound group). Twenty-seven patients from negative ultrasound group (27/169) were randomly selected to undergo shoulder magnetic resonance imaging. None of them had magnetic resonance imaging criteria for adhesive capsulitis. All patients from positive ultrasound group (24/24) underwent shoulder magnetic resonance imaging and 23 of them (23/24) had magnetic resonance imaging signs of adhesive capsulitis, with a sensitivity of 100% and a specificity of 96%. CONCLUSION: In patients with shoulder pain, a thickness greater than 2.0 mm of the axillary recess capsule measured by ultrasound correlates to magnetic resonance imaging signs of adhesive capsulitis with good sensitivity and specificity.

RESUMO

OBJECTIVE: To determine the effectiveness of joint mobilization techniques in the range of motion in adult patients with primary adhesive shoulder capsulitis. METHODS: Systematic review with meta-analysis. The search was performed in the MEDLINE/PubMed, PEDro, CENTRAL, LILACS, EMBASE, CINAHL, Scopus and Web of Science databases. The eligibility criteria were studies that used an oscillatory and/or maintained joint mobilization technique applied alone or added-on to a treatment program in patients with primary adhesive capsulitis at any stage. Two authors carried out the selection of studies and the extraction of data, independently. Risk of bias was evaluated according to the tool proposed by Cochrane. RESULTS: We included 14 studies with variable risk of bias. Posterior mobilization compared to any other technique was not significantly different (0.95 degrees; 95% CI: - 5.93 to 4.02), whereas compared to a control group, the difference is 26.80 degrees (CI 95%: 22.71 to 30.89). When applying a set of joint techniques versus a control group, for abduction the difference is 20.14 degrees (95% CI: 10.22 to 30.05). In both cases, the results are statistically significant, and the effect size is moderate. CONCLUSIONS: The evidence is not conclusive about the effectiveness of joint mobilization. When compared with treatments that do not include manual therapy, joint mobilization seems to have a favorable effect on the range of motion and pain reduction in patients with primary adhesive shoulder capsulitis.

OBJETIVO: Determinar la efectividad de las técnicas de movilización articular en el rango de movimiento en pacientes adultos con capsulitis adhesiva primaria de hombro. MÉTODO: Revisión sistemática con metanálisis. La búsqueda fue realizada en las bases de datos MEDLINE/PubMed, PEDro, CENTRAL, LILACS, EMBASE, CINAHL, Scopus y Web of Science. Los criterios de elegibilidad fueron estudios que utilizaran una técnica de movilización articular oscilatoria y/o mantenida aplicada, sola o adicionada, a un programa de tratamiento en pacientes con capsulitis adhesiva primaria, en cualquier estadio. La selección de estudios y la extracción de datos fueron realizadas por dos autores de forma independiente. El riesgo de sesgo se evaluó según la herramienta propuesta por Cochrane. RESULTADOS: Se incluyeron 14 estudios con variados riesgos de sesgo. La movilización posterior versus otra técnica articular no presenta diferencia de media significativa (- 0,95 grados; intervalo de confianza de 95%; - 5,93 a 4,02), mientras que comparada con un grupo control la diferencia es de 26,80 grados (intervalo de confianza 95%; 22,71 a 30,89), además cuando se aplica un conjunto de técnicas articulares versus un grupo control, para la abducción la diferencia es de 20,14 grados (intervalo de confianza 95%; 10,22 a 30,05). En ambos casos, los resultados son estadísticamente significativos y se aprecia un tamaño de efecto moderado. CONCLUSIONES: La evidencia científica no es concluyente acerca de la efectividad de la movilización articular, dada la heterogeneidad en la metodología y sesgo de los artículos incluidos en esta revisión. Al compararla con tratamientos que no incluyen terapia manual, parecieran favorecer la mejoría del rango de movimiento y reducción del dolor, en pacientes con capsulitis adhesiva primaria de hombro.

RESUMO

ABSTRACT Objective: The aim of this study was to evaluate whether Asian ethnicity is a risk factor for the development of adhesive capsulitis. The secondary aim was to describe the distribution of cases of capsulitis by age group. Methods: A cross-sectional study comparing the rate of adhesive capsulitis in individuals of Asian ethnicity with that of other ethnicities. We excluded patients with fractures and those with symptoms not involving the shoulder. The odds ratio was adjusted for confounding factors by binary logistic regression. Results: A total of 1331 patient records were evaluated and after applying the selection criteria, 814 patients remained. We found 134 cases of adhesive capsulitis (15.6%). The peak of incidence was at 60-64 years in the patients of Asian ethnicity and at 55-59 years in the other patients. The unadjusted odds ratio was 4.2 (CI 95%, 2.4-7.4), while the odds ratio adjusted for sex and diabetes mellitus was 3.6 (CI 95%, 2.0-6.5). Conclusion: Patients of Asian ethnicity showed an independent risk factor for the development of adhesive capsulitis, with an adjusted odds ratio of 3.6. Adhesive capsulitis was more common between 55 and 64 years.

RESUMO Objetivo: Avaliar se a etnia asiática é um fator de risco no desenvolvimento da capsulite adesiva. Os objetivos secundários foram descrever a prevalência da capsulite adesiva no ambulatório especializado em ombro e a dispersão dos casos de capsulite por faixa etária. Métodos: Estudo transversal que comparou a taxa de capsulite adesiva na etnia asiática (casos) com outras etnias (controles). Excluímos pacientes com fraturas e sintomatologia que não envolviam o ombro. O risco relativo foi exposto em razão de chance, ajustado para fatores confundidores por uma regressão logística binária. Resultados: Foram avaliados os prontuários de 1.331 pacientes. Após aplicação dos critérios de seleção, restaram 814. Observamos 134 casos de capsulite adesiva (15,6%). O pico de incidência foi aos 60-64 anos na etnia asiática e 55-59 anos nas demais. A razão de chance não ajustada foi de 4,2 (IC 95%, 2,4 a 7,4), enquanto a ajustada para sexo e diabetes mellitus foi de 3,6 (IC 95%, 2,0 a 6,5). Conclusão: A etnia asiática se mostrou um fator de risco independente para o desenvolvimento da capsulite adesiva, com uma razão de chance ajustada de 3,6. O diagnóstico de capsulite adesiva esteve presente em 15,6% da amostra, com pico entre 55 e 64 anos.

RESUMO

La restricción de movilidad de la articulación glenohumeral genera una disfunción importante en todos los ámbitos del desempeño personal. Diversas patologías del hombro convergen en este cuadro sindromático caracterizado por dolor severo asociado a una restricción de movilidad variable, activa y pasiva, que generalmente es autolimitado y con una resolución espontánea, satisfactoria para la mayoría de los pacientes. Se realiza una revisión narrativa de la etiología, historia natural, presentación clínica, diagnóstico diferencial, los tratamientos más comunes del cuadro sindromático de hombro rígido idiopático y su pronóstico.?La revisión de la literatura, describe una multitud de tratamientos, con resultados variables, lo cual refleja la dificultad encontrada por los clínicos para establecer un tratamiento, teniendo en cuenta que la etiología no esta esclarecida. Una mayor precisión en el diagnóstico nos permitirá establecer un tratamiento efectivo y una reincorporación más predecible a las actividades cotidianas de cada paciente. La elección del tratamiento continua con baja evidencia sujeta a la experiencia del ortopedista tratante.

Restriction of mobility of the glenohumeral joint is associated with a significant dysfunction in all areas of personal performance. Several shoulder conditions merge in this syndrome-type disorder characterised by: severe shoulder pain and reduced active and passive range of motion. It is generally self-limited and resolves spontaneously, which is satisfactory for most patients. A narrative review is presented that describes the aetiology, natural history, clinical presentation, differential diagnosis, the most common treatments, and prognosis of the idiopathic stiff shoulder.The review of the literature describes a multitude of treatments, with variable results, which reflects the difficulties encountered by clinicians to establish a treatment, considering that the aetiology is not clear. ?A greater precision in the diagnosis would enable an effective treatment to be established, and a more predictable return to the patient's daily tasks.
