Abstract Background: Despite the criteria already established for the classification of knee osteoarthritis (OA), a radiographic and/or clinical knee OA diagnosis usually occurs in cases of fully manifest or more advanced disease, which can make health promotion, prevention, and functional rehabilitation in more advanced stages of the disease less effective. In addition, radiographic knee OA can generate more financial costs for health services. Therefore, developing and validating screening instruments to assess the probability of development and progression of knee OA would be of great value for both clinical practice and science. Objective: To cross-culturally adapt and investigate the measurement properties of the Knee OA Pre-screening Questionnaire Brazilian version. Methods: A total of 250 individuals of both sexes aged between 35 and 92 years [(mean (standard deviation): 63 (11) years old; 74.1 (15.1) kg; 1.59 (0.09) m; 29.38 (5.44) kg/m2] participated in this study. The cross-cultural adaptation and analyses of the measurement properties of the KOPS Brazilian version included: (1) assessment of conceptual and item equivalence; (2) assessment of semantic equivalence; (3) assessment of operational equivalence; and (4) assessment of measurement equivalence, reliability, and validity. Results: Cronbach's alpha for the internal consistency among the six components of the KOPS Brazilian version was 0.71. The test-retest 72 h apart for each component resulted in a coefficient correlation intraclass ranging from 0.74 to 1.00. The probability of an individual randomly chosen from the population having KL ≥ 1 and KOPS Brazilian version ≥ 21 points was 0.74 (area under the curve of the Receiver Operating Characteristic – AUC of ROC); furthermore, the AUC for KL ≥ 2 and the KOPS Brazilian version ≥ 23 points was 0.77. Conclusion: The KOPS Brazilian version is a reliable and valid instrument for early screening of knee OA in individuals aged 35 years and over in the Brazilian context.

RESUMO JUSTIFICATIVA E OBJETIVOS: O ambiente hospitalar é considerado como insalubre, além disso, a atividade laboral desempenhada pelos profissionais de enfermagem apresenta diversos fatores de risco para o desenvolvimento de dor. Nesse sentido, o presente estudo teve por objetivo analisar os distúrbios musculoesqueléticos na equipe de enfermagem e correlacionar com o nível de atividade física, características antropométricas e o perfil profissional no Hospital Universitário em Petrolina, Pernambuco. MÉTODOS: Trata-se de um estudo transversal, com 143 profissionais de enfermagem, sendo 122 do sexo feminino (37±7 anos) e 21 do sexo masculino (33±6 anos). Os indivíduos responderam aos questionários Internacional de Atividade Física e ao Nórdico de Sintomas Osteomusculares. RESULTADOS: Foi constatada a presença de dor em 77 voluntários, o que equivale a 53,8% da amostra. Em 35 (24,4%) voluntários houve a presença de distúrbios musculoesqueléticos em mais de um segmento corporal. Quanto à distribuição de dor por segmento corporal, foram observadas maiores prevalências na região lombar e nos joelhos, ambas com 17,4%. Além disso, foram verificadas associações entre o sexo masculino e dor nos cotovelos (RP=5,5, IC 95%:1,1;25,5, p=0,028) e tornozelos (RP=5,1, IC 95%:1,3;19,2, p=0,016), e dor e inatividade física para os segmentos em cotovelos (RP=3,4, IC 95%:1,1;10,3, p=0,027) e joelhos (RP= 2,4, IC95%: 1,1; 5,0, p=0,021). CONCLUSÃO: Observou-se que a prevalência de dor na equipe de profissionais analisada foi elevada, e que fatores de risco como a inatividade física e o sexo masculino, foram associados com maior surgimento dos distúrbios musculoesqueléticos.

ABSTRACT BACKGROUND AND OBJECTIVES: The hospital environment is considered to be unhealthy, and, moreover, the work performed by nursing professionals presents several risk factors for the development of pain. In this sense, the present study aims to analyze the musculoskeletal disorders in the nursing team and to correlate with the level of physical activity, anthropometric characteristics and the professional profile at the University Hospital in Petrolina, Pernambuco. METHODS: This was a cross-sectional study with 143 nursing professionals, of which 122 were female (37±7 years) and 21 were male (33±6 years). The individuals answered the International Physical Activity Questionnaire and the Nordic Musculoskeletal Questionnaire. RESULTS: Pain was reported in 77 volunteers, which corresponds to 53.8% of the sample. In 35 (24.4%) volunteers there was the presence of musculoskeletal disorders in more than one body segment. Regarding pain distribution by body segment, the higher prevalence's were observed in the lumbar region and the knees, both with 17.4%. In addition, there were associations between being male and pain in the elbows (PR=5.5, 95% CI: 1.1, 25.5, p=0.028) and ankles (PR=5.1, 95% CI: 1.3; 19.2, p=0.016), and pain and physical inactivity for the elbow segments (PR=3.4, 95% CI: 1.1, 10.3, p=0.027) and knees (PR=2.4, 95% CI: 1.1, 5.0, p=0.021). CONCLUSION: It can be noticed that the prevalence of pain in the team of professionals analyzed was high and that the risk factors, such as physical inactivity and being male were associated with a greater onset of musculoskeletal disorders.

RESUMO JUSTIFICATIVA E OBJETIVOS: Tanto os fatores biomecânicos quanto emocionais podem contribuir para o surgimento de distúrbios osteomusculares em fisioterapeutas que atuam dentro de um hospital; porém ainda não se sabe se esses profissionais apresentam dor e desconforto musculoesquelético relacionados ao setor e ao tempo de trabalho. Os objetivos deste estudo foram comparar o autorrelato de dor e o desconforto musculoesquelético dos fisioterapeutas da unidade de terapia intensiva e enfermarias e avaliar retrospectivamente, em 12 meses de trabalho, o autorrelato de dor e desconforto musculoesquelético dos fisioterapeutas desses setores. MÉTODOS: O autorrelato de dor e o desconforto musculoesquelético dos 18 fisioterapeutas que atuam nesse hospital foi avaliado pelo Questionário Nórdico de Sintomas Osteomusculares, no período atual (T1) e comparados retrospectivamente com os dados avaliados no período admissional (T0). RESULTADOS: Não houve associação entre o autorrelato de dor e o desconforto musculoesquelético e os setores de atuação desses profissionais, porém houve uma associação temporal entre o autorrelato de dor e o desconforto musculoesquelético na unidade de terapia intensiva, nas regiões de pescoço (p=0,043), ombros (p=0,009), parte superior das costas (p=0,043), parte inferior das costas (p=0,043) e região de quadril e coxas (p=0,027). A segunda jornada de trabalho desses fisioterapeutas não se mostrou associada com a dor e o desconforto musculoesquelético. CONCLUSÃO: O autorrelato de dor e desconforto musculoesquelético de fisioterapeutas desse hospital universitário, tanto no período admissional (T0) quanto após 12 meses de trabalho (T1) não se mostrou associado com o setor de atuação desses profissionais. Depois de 12 meses, os fisioterapeutas da unidade de terapia intensiva apresentaram aumento no autorrelato de dor e desconforto musculoesquelético.

ABSTRACT BACKGROUND AND OBJECTIVES: Both biomechanical and emotional factors may contribute to the development of work-related musculoskeletal disorders in physical therapists working at a hospital, but we still do not know if these professionals present musculoskeletal symptoms related to the sector and working time. The objective of this study was to compare the self-report of pain and musculoskeletal discomfort of the physical therapists working in the intensive care unit and ward of a university hospital and retrospectively evaluate, 12 months of work, self-report of pain and musculoskeletal discomfort of physiotherapists in these sectors. METHODS: The self-report of pain and the musculoskeletal discomfort of the 18 physical therapists working in this hospital were evaluated by the Nordic Musculoskeletal Questionnaire in the admission period (T0) and after 12 months (T1). RESULTS: No association was found between the self-report of pain and musculoskeletal discomfort and the working sector of these professionals. However, there was a temporal association between the self-report of pain and musculoskeletal complaints in the intensive care unit sector in the following regions: neck (p=0.043), shoulders (p=0.009), upper back (p=0.043), lower back (p=0.043) and hip and thigh region (p=0.027). The second shift of these professionals was not associated with pain and musculoskeletal discomfort. CONCLUSION: The self-report of pain and musculoskeletal discomfort of physical therapists of this university hospital, both in the admission period (T0) and after 12 months of work (T1) was not associated with the sector in which they work. However, after 12 months, the physical therapists working in the intensive care unit showed an increase in the amount of self-report of pain and musculoskeletal discomfort.

ABSTRACT BACKGROUND AND OBJECTIVES: Work-related musculoskeletal disorders have shown a high prevalence among workers, among these, law enforcement officers have been greatly affected. The aim of this study was to analyze the occurrence of musculoskeletal disorders symptoms in the Ostensive Motorcycle Patrol Group of the Military Police of Pernambuco, PE. METHODS: This was a cross-sectional study developed from February to June 2016. The subjects were 28 police officers from the Ostensive Motorcycle Patrol Group, of the 5th Battalion of the Military Police. Data was collected through a self-administered questionnaire with sociodemographic variables and professional characteristics. The Nordic Musculoskeletal Questionnaire and the visual analog scale were used. RESULTS: In the study sample, most of the individuals were male with an average of 62±8 working hours per week. Regarding the presence of musculoskeletal symptoms, the most affected anatomical region was the back, followed by the knees and then the chest. As for the pain perception of the subjects, the spine and lower limbs showed higher pain intensity when compared to other regions. Most of the sample believe that musculoskeletal symptoms are related to work. CONCLUSION: The findings in this study demonstrate the presence of musculoskeletal symptoms in the studied population. The analysis of the musculoskeletal disorders of these police officers will serve as an input for the planning of intervention actions to improve the general conditions of the service provided by the Ostensive Motorcycle Patrol Group.

OBJECTIVE: To evaluate and compare rearfoot alignment and medial longitudinal arch index during static postures in runners, with and without symptoms and histories of plantar fasciitis (PF). INTRODUCTION: PF is the third most common injury in runners but, so far, its etiology remains unclear. In the literature, rearfoot misalignment and conformations of the longitudinal plantar arch have been described as risk factors for the development of PF. However, in most of the investigated literature, the results are still controversial, mainly regarding athletic individuals and the effects of pain associated with these injuries. METHODS: Forty-five runners with plantar fasciitis (30 symptomatic and 15 with previous histories of injuries) and 60 controls were evaluated. Pain was assessed by a visual analogue scale. The assessment of rearfoot alignment and the calculations of the arch index were performed by digital photographic images. RESULTS: There were observed similarities between the three groups regarding the misalignments of the rearfoot valgus. The medial longitudinal arches were more elevated in the group with symptoms and histories of PF, compared to the control runners. CONCLUSIONS: Runners with symptoms or histories of PF did not differ in rearfoot valgus misalignments, but showed increases in the longitudinal plantar arch during bipedal static stance, regardless of the presence of pain symptoms.

A literatura sugere que mudanças no ângulo Q podem alterar o arco plantar longitudinal e que um mau alinhamento do retropé poderia também modificar a postura do antepé. Contudo, não foram encontrados estudos que correlacionem quantitativamente, na postura ortostática bipodal, todos esses segmentos. Assim, o propósito deste estudo foi avaliar quantitativamente e verificar eventuais correlações entre o ângulo Q, arco plantar longitudinal, alinhamento frontal do tendão do calcâneo e antepé, na postura ortostática bipodal, por meio de fotogrametria. Foram avaliados 30 indivíduos jovens (60 membros inferiores) de ambos os sexos, com idade entre 18 e 24 anos. Foi feita captura fotográfica digital no plano frontal anterior de joelho e antepé; no plano frontal posterior, do tendão do calcâneo; e da impressão plantar exposta no podoscópio. Os dados foram analisados estatisticamente e o nível de signficância fixado em 5%. Foram obtidas as seguintes correlações entre: ângulo Q X arco plantar, r=0,29 (p=0,021); ângulo Q X antepé, r=0,23 (p=0,092); ângulo Q X tendão do calcâneo, r=0,06 (p=0,627); arco plantar X antepé, r=0,09 (p=0,464); arco plantar X tendão do calcâneo, r=-0,05 (p=0,680); e antepé X tendão do calcâneo, r=-0,02 (p=0,857). A única correlação significativa encontrada, embora fraca, foi entre o ângulo Q e o arco plantar longitudinal medial, o que sugere cautela ao se inferirem correlações entre estruturas dos membros inferiores.

Literature often reports that changes in the Q angle may alter the longitudinal plantar arch and that a misalignment of the rearfoot might also modify forefoot position. However, no studies could be found that quantitatively establish correlations between those lower limb segments in orthostatic bipedal posture. The goal of this study was to quantitatively assess possible correlations between the Q angle, longitudinal plantar arch, frontal forefoot and rearfoot alignment in bipedal orthostatic position, by means of photogrammetry. Thirty individuals (60 lower limbs) of both sexes, aged 18 to 24 years old, were photographed at knee and forefoot anterior frontal plane, rearfoot posterior frontal plane (calcanean tendon), and footprint (by electronic high-resolution podoscopy). Data were statistically analysed and the significance level set at 5%. The following correlations were found: Q angle X plantar arch, r=0.29 (p=0.021); Q angle X forefoot, r=0.23 (p=0.092); Q angle X calcanean tendon, r=0,06 (p=0.627); plantar arch X forefoot, r=0.09 (p=0.464); plantar arch X calcanean tendon, r=-0.05 (v=0.680); and forefoot X calcanean tendon, r=-0,02 (p=0,857). The only significant correlation found, although weak, was between the Q angle and longitudinal medial plantar arch, which suggests cautiousness when inferring correlations between lower limb structures.

Na prática fisioterapêutica, pressupõe-se que alterações posturais do membro inferior influenciem a biomecânica e função dos demais complexos durante o movimento. No entanto, a literatura sobre a relação entre desalinhamentos estáticos do joelho e possíveis alterações dinâmicas ainda é escassa e inconclusiva. Assim, buscou-se avaliar o efeito do alinhamento frontal estático do joelho sobre a distribuição da pressão plantar durante a marcha. Foram avaliados inicialmente 44 adultos jovens assintomáticos. Por fotogrametria digital, mediu-se o ângulo frontal do joelho, classificado como normal (170° a 175°), valgo <170º e varo >175°. Dado o baixo número de valgos, foram analisados dois grupos: de joelhos normais (n=18) e de joelhos varos (n=23). A distribuição da pressão plantar foi avaliada durante a marcha em cinco áreas. Os grupos mostraram-se estatistica-mente semelhantes em todas as variáveis cinéticas avaliadas em todas as áreas plantares. Joelhos normais apresentaram significativa correlação com o tempo de contato no antepé lateral e médio-pé; e os varos, correlação com a área e tempo de contato em duas e três áreas plantares, e com a pressão integral no antepé lateral. Os resultados mostraram que o desalinhamento frontal de 3° do joelho, embora com moderada correlação, não influencia a distribuição de cargas na superfície plantar durante a marcha. Sugere-se pois que a avaliação clínica não se limite à avaliação articular estática do joelho, mas inclua atividades dinâmicas.

In physical therapy practice, it is assumed that lower-limb posture changes may influence other complexes' biomechanics or function during movement. However, literature on the relationship between static knee alignment and possible dynamic changes is still scarce and inconclusive. This study assessed the effect of static frontal knee alignment on plantar pressure distribution during gait. At first 44 young asymptomatic adults were evaluated. Front knee angles were measured by digital photogrammetry and classified as normal (170° to 175°), valgus <170°, or varus >175°. Given the low number of valgus found, two groups were analysed: normal knees (n=18) and varus knees (n=23). Plantar pressure distribution was measured during gait in five plantar surface areas. Groups were found to be statistically similar in all kinetic variables assessed in all plantar surface areas. Normal knees showed significant correlation with the contact time at lateral forefoot and midfoot. Varus knees showed correlation with contact area and time at respectively two and three plantar areas, and with full pressure at lateral forefoot. Results thus show that a 3° frontal knee malalignment, though with moderate correlation, does not influence pressure distribution on plantar surface during gait. It is hence suggested that clinical evaluation should not be limited to static knee assessment, but rather include dynamic activities.
