Low back pain (LBP) is a major public health issue. There is lack of research on this disorder affecting urban cleaning workers. A cross-sectional study was conducted to describe the prevalence of LBP, occupational and extra-occupational characteristics, as well as associated factors in these workers. A census was performed with 624 workers in Salvador, Brazil, using a questionnaire administered by an interviewer in 2010. Cases of LBP were defined by reported symptoms of pain in the previous 12 months, lasting more than a week or with monthly minimum frequency, which led to restrictions at work or to seeking medical attention, or in cases when respondents had a severity score > 3 on a numerical scale from 0 to 5. Physical demands at work were measured on a numerical 6-point scale with 14 variables. Psychosocial demands were measured using the Job Content Questionnaire. Sociodemographic factors, lifestyle habits and domestic work were evaluated. Multiple logistic regression (LR) was used to identify factors associated with LBP, for which the prevalence was 37.0%. Among them, 62.8% of workers felt pain in the last 7 days. LBP was associated with longer working hours, flexion and trunk rotation, psychosocial demands, working directly in collection and low schooling. Dynamic work (walking, running) served as a protective factor. It was concluded that many workers develop their activity at the presence of pain. The results emphasize the need for preventive measures through multifactorial approach encompassing adaptations in physical environment and changes in work organization.

The increased generation of garbage has become a problem in large cities, with greater demand for collection services. The collector is subjected to high workload. This study describes the work in garbage collection service, highlighting the requirements of time, resulting in physical and psychosocial demands to collectors. Ergonomic Work Analysis (EWA) -a method focused on the study of work in real situations was used. Initially, technical visits, global observations and unstructured interviews with different subjects of a garbage collection company were conducted. The following step of the systematic observations was accompanied by interviews conducted during the execution of tasks, inquiring about the actions taken, and also interviews about the actions, but conducted after the development of the tasks, photographic records and audiovisual recordings, of workers from two garbage collection teams. Contradictions between the prescribed work and activities (actual work) were identified, as well as the variability present in this process, and strategies adopted by these workers to regulate the workload. It was concluded that the insufficiency of means and the organizational structure of management ensue a situation where the collection process is maintained at the expense of hyper-requesting these workers, both physically and psychosocially.

INTRODUÇÃO: Disfunção temporomandibular (DTM) é caracterizada por um conjunto de alterações funcionais, que envolvem fatores predisponentes, iniciantes e perpetuantes. Considerando que os desvios posturais desorganizam a harmonia corporal entre a postura da mandíbula e todo o sistema esquelético, várias modalidades fisioterapêuticas foram propostas no tratamento da DTM, incluindo a Reeducação Postura Global (RPG). OBJETIVO: Avaliar sistematicamente as evidências sobre a eficácia da RPG no tratamento da dor em indivíduos com DTM. MÉTODOS: Revisão sistemática realizada pesquisa nas bases de dados, maio a setembro 2017, Pubmed, Biblioteca Virtual em Saúde (Lilacs, Scielo e Medline), PEDro e Cochrane Library. Os critérios de inclusão: Ensaios clínicos randomizados (ECR) e Ensaios clínicos controlados (ECC); artigos publicados em língua inglesa, portuguesa e espanhola; que abordavam sobre o tratamento com RPG; com indivíduos adultos > 18 e ≤60 anos; diagnosticados com DTM; que continham avaliação da dor. Excluídos: estudos duplicados; que utilizaram exercícios para pacientes pós-cirúrgico e que apresentassem doenças sistêmicas ou qualquer afecção que afetasse o sistema osteomioarticular; que avaliaram pacientes com histórico de trauma facial ou cervical e em uso de medicamentos. RESULTADOS: Um total de 349 artigos foram encontrados, que após a eliminação de duplicatas, filtragem de títulos, resumos e leitura de texto completo foram incluídos na pesquisa três estudos, o que evidenciou a eficácia da RPG na redução da dor. CONCLUSÃO: Considerando os resultados obtidos neste estudo, foi possível concluir que a RPG demonstra ser eficaz na redução da dor presente na DTM. Porém, faz-se necessários mais ensaios clínicos randomizados com maior rigor metodológico, protocolos mais bem definidos, que possam auxiliar na tomada de decisão clínica e que contemplem também a comparação do tratamento entre homens e mulheres.

O objetivo deste estudo é investigar a frequência de cervicalgia e a associação com dependência do uso de smartphone e incapacidade cervical em graduandos de fisioterapia. Trata-se de um estudo observacional de corte transversal realizado com estudantes de fisioterapia de uma universidade pública do estado da Bahia, entre novembro de 2019 e fevereiro de 2020. Foram utilizados uma ficha de avaliação com dados sociodemográficos, o questionário Neck Disability Index (NDI) para avaliação da incapacidade cervical e o questionário Smartphone Addiction Inventory (SPAI-BR) para rastreio de comportamento dependente de smartphone. As análises foram conduzidas no pacote estatístico Epi-Info (V.3.5.2), sendo estabelecido nível de significância com valor de p < 0,05. A amostra foi composta por 150 estudantes de fisioterapia, sendo a maioria mulheres, com idade média de 22,0 ± 3,0 anos. A frequência de dor cervical no último ano ocorreu em 66% dos entrevistados, com associação estatisticamente significativa apenas para a variável de dor no último ano, em 97% dos estudantes, com o posicionamento cervical em flexão durante o uso de smartphone (p = 0,003). A frequência de cervicalgia nos últimos 12 meses foi elevada nessa população. Este estudo não encontrou associação entre essas variáveis com dependência do uso smartphone e incapacidade cervical em estudantes universitários, entretanto, revelou uma associação entre a frequência de cervicalgia no último ano e o posicionamento em flexão da coluna cervical durante o uso de smartphone.
