The Brazilian version of the High-Activity Arthroplasty Score: cross-cultural adaptation

ABSTRACT BACKGROUND: The High Activity Arthroplasty Score (HAAS) is a self-administered questionnaire, developed in British English, that reliably and validly measures the levels of sports activities in patients following hip and knee arthroplasty surgery. OBJECTIVE: To cross-culturally adapt the HAAS to Brazilian Portuguese language. DESIGN AND SETTING: A cross-sectional study was conducted at a public university hospital in Brazil. METHODS: The Brazilian version of the HAAS was created through a six-step process: translation, synthesis, committee review, pretesting, back-translation, and submission to developers. The translation step was conducted by two independent bilingual translators, both native speakers of Brazilian Portuguese. The back-translation was performed by an independent translator, a native speaker of British English. To ensure the questionnaire's comprehensibility, 46 volunteers (51% men; average age 34-63) participated in the pre-testing step. RESULTS: The cross-cultural adaptation process necessitated modifications to certain terms and expressions to achieve cultural equivalence with the original HAAS. CONCLUSION: The HAAS has been translated from English into Brazilian Portuguese and culturally adapted for Brazil. The validation process for HAAS-Brazil is currently underway.

Condutas cinesioterapêuticas no tratamento das tendinopatias do manguito rotador em atletas de voleibol de quadra / Kinesiotherapeutic conducts in the treatment of rotator cuff tendinopathies in indoor volleyball athletes

Introdução: o ombro do jogador de voleibol é suscetível a lesões resultantes de sobrecargas biomecânicas e movimentos repetitivos. As frequentes queixas de dor nessa articulação evidenciam o elevado volume de ações motoras unilaterais em alta velocidade acima da cabeça, atingindo o manguito rotador (MR) e gerando limitação funcional na prática desportiva. As tendinopatias do MR, formado pelos músculos subescapular, redondo menor, infraespinhal e supraespinhal, atingem comumente os tendões do supraespinhal e do infraespinhal. Objetivo: descrever as condutas cinesioterapêuticas utilizadas no tratamento das tendinopatias do MR em atletas de voleibol de quadra. Metodologia: pesquisaram-se as bases de dados MEDLINE, SciELO e BVS. Descritores: lesões do ombro, manguito rotador, atletas, voleibol e Terapia por Exercício (pesquisados em inglês), associados dois a dois ou três a três, dentre os quais o termo atletas ou voleibol sempre foi mantido. Foram incluídos artigos de revisão, artigos originais, ensaios clínicos e estudos de coorte publicados em português e inglês, entre os anos de 2009 e 2019. Resultados: inicialmente a busca resultou em 480 artigos. Após o processo de seleção, seis estudos foram revisados na íntegra e incluídos na síntese qualitativa. Conclusão: as principais condutas cinesioterapêuticas descritas foram: fortalecimento dos rotadores externos, dos músculos do tronco, da coluna e periescapulares, alongamento da região posterior do ombro e mobilizações articulares.

Introduction: the volleyball player's shoulder is susceptible to injuries resulting from biomechanical overloads and repetitive movements. The frequent complaints of pain in this joint highlight the high volume of unilateral motor actions at high speed above the head, reaching the rotator cuff (RC) and generating functional limitation in sports. RC tendinopathies, formed by the subscapularis, teres minor, infraspinatus and supraspinatus muscles, commonly affect the supraspinatus and infraspinatus tendons. Objective: to describe the kinesiotherapeutic conducts used in the treatment of RC tendinopathies in indoor volleyball athletes. Methodology: MEDLINE, SciELO and VHL databases were searched. Descriptors: shoulder injuries, rotator cuff, athletes, volleyball and Exercise Therapy (searched in English), associated two by two or three by three, among which the term athletes or volleyball was always maintained. Review articles, original articles, clinical trials and cohort studies published in Portuguese and English between 2009 and 2019 were included. Results: initially the search resulted in 480 articles. After the selection process, six studies were fully reviewed and included in the qualitative synthesis. Conclusion: the main kinesiotherapeutic procedures described were strengthening of the external rotators, trunk, spine and periscapular muscles, stretching of the posterior region of the shoulder and joint mobilizations.

Validation of the Brazilian version of the Hip Sports Activity Scale (HSAS) for patients with femoroacetabular impingement: a cross-sectional study

ABSTRACT BACKGROUND: The Hip Sports Activity Scale (HSAS) is a hip-specific instrument for assessing the present levels of physical activity among patients with femoroacetabular impingement (FAI) syndrome. When evaluating treatment outcomes in patients with FAI syndrome, it is necessary to use joint-specific instruments and ones that can evaluate the levels of physical activity in these patients, such as the HSAS-Brazil. OBJECTIVE: To validate the HSAS-Brazil among a group of physically active patients after arthroscopic treatment of FAI syndrome. DESIGN AND SETTING: Cross-sectional research of quantitative and qualitative types using data obtained from July 2018 to October 2019. METHODS: A total of 58 patients of both genders diagnosed with FAI syndrome and who had undergone hip arthroscopy participated in this research. To establish reliability and validity, patients first answered the Brazilian versions of the 12-Item Short-Form Health Survey (SF-12), Nonarthritic Hip Score (NAHS), and HSAS; after a 48-hour interval, they answered the HSAS-Brazil again. RESULTS: For test-retest reliability, the interclass correlation was 0.908 (P < 0.001). The HSAS-Brazil correlated to the NAHS-Brazil (r = 0.63, P < 0.001), as well as the SF-12 (Physical Health) (r = 0.42, P = 0.001). CONCLUSION: The HSAS-Brazil was validated and proved to be a reliable and valid scale to assess sports activity levels in physically active patients with FAI syndrome after arthroscopic treatment.

Acromial type in Brazilian young adults: a radiological study / Tipo acromial em adultos jovens brasileiros: um estudo radiológico

Introduction: curved and hooked acromia play a key role in shoulder impingement syndrome. Little is known about acromial type in the Brazilian population. Aim: To describe the acromial profile of Brazilian young adults; to evaluate its correlation with gender and handedness and the occurrence of symmetry between the genders. Methodology: forty acromia in 20 Brazilian adults of both genders, aged 21-25 years, were studied. The acromial type was classified through the Bigliani/Epstein method using radiographs in supraspinatus outlet view. Results: as there was no gender difference in occurrences of acromial type, we considered the male and female groups together. Thus, among the 20 right acromia, we found 5 type I (25%), 8 type II (40%) and 7 type III (35%). Among the 20 left acromia, we found 4 type I (20%), 11 type II (55%) and 5 type III (25%). The only left-handed volunteer (100%) presented acromial type III in both the right and the left shoulder. Among the 19 right-handed volunteers, 5 (26.3%) presented right acromion type I, 8 (42.1%) had type II and 6 (31.6%) had type III; for the left acromion, 4 (21.1%) presented type I, 11 (57.9%) had type II and 4 (21.1%) had type III. Acromial symmetry occurred in 60% of females and 70% of males. Conclusion: type II acromion was predominant, in both the right and the left shoulder in Brazilian young adults. There was no correlation between acromial type and gender. It was not possible to analyze the correlation between acromial type and handedness. Acromial type tended to be symmetrical in our sample.

Introdução: o acrômio curvo e gancho desempenham um papel fundamental na Síndrome do impacto do ombro. Pouco se sabe sobre o tipo acromial na população brasileira. Objetivo: descrever o perfil do tipo acromial em adultos jovens brasileiros e avaliar sua correlação com o gênero e a lateralidade e a ocorrência de simetria entre os sexos. Metodologia: foram estudados 40 acrômios de 20 adultos brasileiros, de ambos os sexos, com idade entre 21 e 25 anos. O tipo acromial foi classificado pelo método de Bigliani/ Epstein nas radiografias de perfil de escápula. Resultados: como não houve diferença na ocorrência do tipo acromial quanto ao gênero, consideramos os grupos masculino e feminino juntos. Assim, dos 20 acrômios direitos, foram encontrados 5 (25%) do tipo I, 8 (40%) do tipo II e 7 (35%) do tipo III, enquanto que dos 20 acrômios esquerdos, foram encontrados 4 (20%) tipo I, 11 (55%) tipo II e 5 (25%) tipo III. O único voluntário canhoto (100%) apresentou para o ombro direito e esquerdo o tipo acromial III. Dos 19 voluntários destros, 5 (26,3%) apresentavam acrômio direito tipo I, 8 (42,1%) tipo II e 6 (31,6%) tipo III; para o acrômio esquerdo, 4 (21,1%) apresentavam tipo I, 11 (57,9%) tipo II e 4 (21,1%) tipo III. A simetria acromial ocorreu nos grupos feminino (60%) e masculino (70%). Conclusão: o acrômio tipo II foi o mais predominante para os ombros direito e esquerdo em adultos jovens brasileiros. Não houve correlação entre o tipo de acromial e o gênero. Não foi possível analisar a correlação entre o tipo acromial e a lateralidade. O tipo acromial tende a ser simétrico em na amostra estudada.

Confiabilidade interavaliador do método de Bigliani para classificação do tipo acromial / Inter-rater reliability of the method of Bigliani for classifying acromial type

Introdução: em 1875, Hamilton identificou o formato do acrômio como uma etiologia de dor no ombro. Neer, em 1972, descreveu a síndrome do impacto no ombro como uma relação de causa e efeito entre a morfologia do acrômio e o impacto subacromial. Em 1986, Bigliani et al. apresentaram um esquema de classificação do acrômio de acordo com o formato de sua superfície inferior: plano (tipo I), curvo (tipo II) e gancho (tipo III). Em 1993, Epstein et al. proporam que o acrômio tipo II apresentaria um declive em seu terço médio e o tipo III no seu terço anterior. Objetivo: avaliar a reprodutibilidade/confiabilidade interavaliador do método de Bigliani et al. (1986) refinado por Espstein et al. (1993) para a classificação do tipo acromial. Metodologia: casuística composta por 20 voluntários brasileiros, de ambos os gêneros, entre 21-25 anos. A incidência radiográfica utilizada para visualizar o formato do acrômio foi perfil de escápula. O tipo acromial foi classificado por três avaliadores. A reprodutibilidade e confiabilidade foram avaliadas pelo teste McNemar e pelo índice Kappa. Resultados: teste de McNemar com p > 0,05; índice Kappa entre 0,61 e 0,8; e probabilidade de significância p de Kappa < 0,05 confirmam a muito boa reprodutibilidade e confiabilidade do método para classificação do tipo acromial entre os três avaliadores. Conclusão: o método de Bigliani et al. (1986) refinado por Epstein et al. (1993) para classificação do tipo acromial mostrou concordância entre todos os avaliadores confirmando a muito boa reprodutibilidade e confiabilidade entre os avaliadores do estudo.

Introduction: in 1875, Hamilton identified that acromion shape was an etiology for shoulder pain. In 1972, Neer described shoulder impact syndrome as a cause and effect relationship between acromion morphology and subacromial impact. In 1986, Bigliani et al. presented an acromion classification scheme according to the shape of its lower surface: flat (type I), curved (type II) and hook (type III). In 1993, Epstein et al. proposed that the type II acromion would have a slope in its middle third and type III in its anterior third. Objective: to evaluate the inter-rater reproducibility and reliability of the method of Bigliani et al. (1986) for classifying acromial type, as refined by Epstein et al. (1993). Methodology: this was a case series composed of 20 Brazilian volunteers of both genders, aged 21-25 years. The shape of the acromion was visualized radiographically using the supraspinatus outlet view. Acromial type was classified by three evaluators. Reproducibility and reliability were assessed using the McNemar test and kappa index. Results: the McNemar test showed probability p > 0.05 and the kappa index was between 0.61 and 0.8 significant result: p < 0.05. These confirmed that this method had very good reproducibility and reliability for classifying acromial type among the three evaluators. Conclusion: the method of Bigliani et al. (1986) for classifying acromial type, as refined by Epstein et al. (1993) showed agreement among all the evaluators. This confirmed that there was very good reproducibility and reliability among the evaluators of this study.

Validation of the Brazilian version of the Hip Outcome Score (HOS) questionnaire.

BACKGROUND: The Hip Outcome Score (HOS) was developed to evaluate physically active patients with hip disease but without severe degenerative change. A translation and cultural adaptation into Brazilian Portuguese was previously conducted. The aim of this study was to validate the Brazilian version of the HOS (HOS-Brazil) among a group of physically active patients with a diagnosis of femoroacetabular impingement (FAI) or greater trochanteric pain syndrome (GTPS). METHODS: The following questionnaires were applied: the HOS-Brazil; the validated Brazilian versions of the Nonarthritic Hip Score (NAHS) and the 12-Item Short-Form Health Survey (SF-12). The psychometric properties analyzed with regard to the validation process were reliability and validity. Internal consistency and intra-rater test-retest reliabilities were analyzed using Cronbach's alpha and the intraclass correlation coefficient (ICC) statistical tests based on test-retest agreement. Construct and content validities were examined using Pearson's correlation coefficient. Content validity was also analyzed based on evidence of floor, ceiling, or both types of effects from the questionnaires. RESULTS: A total of 70 male and female patients were selected, aged between 19 and 70 years old. The internal consistency and intra-rater test-retest reliability values were high (Cronbach's α > 0.9; ICC > 0.9). The questionnaire showed acceptable convergent (r > 0.7) and divergent (r < 0.4) validities. No floor or ceiling effects were observed. CONCLUSION: The HOS-Brazil was validated. Additional studies are underway to evaluate its responsiveness.

Efeito do treinamento físico aeróbico na prevenção e terapêutica da doença aterosclerótica em modelo experimental de aterosclerose / Role of aerobic physical training in atherosclerotic disease prevention and treatment in an experimental model of atherosclerosis

O conhecimento de que o exercício é benéfico na doença aterosclerótica é baseado principalmente em estudos epidemiológicos. O objetivo deste trabalho foi investigar se o treinamento físico preventivo ou terapêutico altera a evolução da placa aterosclerótica. Camundongos LDLr-/- com 16 semanas de vida foram separados em dois programas: preventivo e terapêutico. Animais do programa preventivo receberam dieta normal ou aterogênica por 14 semanas. O treinamento físico foi iniciado concomitantemente ao início da dieta. Animais do programa terapêutico receberam dieta normal ou aterogênica por 28 semanas. O treinamento físico foi iniciado após 14 semanas do início da dieta, com placas bem estabelecidas. O treinamento físico aeróbico moderado foi realizado em esteira rolante, por 60 min, 5 dias/sem, durante 14 semanas. Massa corporal, pressão arterial caudal e freqüência cardíaca foram registradas. Lipoproteínas plasmáticas foram separadas por FPLC e colesterol total foi dosado por métodos enzimáticos. Foram quantificados tamanho, conteúdo de gordura e de colágeno da placa por coloração de oil-red O e picro-sirius. Citocinas TNF-, IL-6 foram medidas por Elisa. MMP-9 plasmática foi medida por zimografia. Marcadores inflamatórios teciduais, MMP-9, CD40/CD40L e nitrotirosina, foram medidos na placa por imunohistoquímica. O treinamento físico não modificou o tamanho da placa, mas tornou a placa mais estável por aumentar o conteúdo de colágeno. O treinamento físico diminuiu o conteúdo de gordura da placa, os fatores de risco e o CD40 somente no programa preventivo. Nenhuma alteração foi notada nos marcadores inflamatórios circulantes e na expressão de MMP-9 e formação de nitrotirosina na placa aterosclerótica.

The knowledge that exercise exerts beneficial effects on atherosclerotic disease is mainly based on epidemiological studies. Our aim was to investigate the effect of preventive and therapeutic exercise programs on atherosclerotic plaque formation and development. Sixteen-week-old LDLr-/- mice were randomly divided into preventive and therapeutic programs. Preventive programs mice received normal or atherogenic diet for 14 weeks. Exercise training started at the same time of dieting. Therapeutic programs mice received normal or atherogenic diet for 28 weeks. Exercise training started after 14 weeks of dieting when atherosclerosis plaques were already established. Moderate intensity aerobic exercise training was performed on a motor treadmill for 60 min, 5 days/wk, during 14 weeks. Body mass, caudal blood pressure and heart rate were registered. Plasma lipoproteins were separated by FPLC and total cholesterol was determined by enzymatic methods. Cross sections of aortic root were stained with oil-red O for plaque size and fat content. Aorta longitudinal sections were stained with picro-sirius for collagen content. TNF- and IL-6 cytokines were measured by Elisa. Plasmatic MMP-9 was determined by zimography. Inflammatory tissue markers, MMP-9, CD40/CD40L and nitrotirosine, were measured by immunohistochemistry. We concluded that exercise training did not modify plaque size, but turned it into a more stable one by increasing its collagen content. Exercise training reduced plaque fat content, risk factors and plaque CD40 expression only in the preventive program. No difference in systemic inflammatory markers, and in plaque MMP-9 expression and nitrotirosine formation was noted.
