Dor musculoesquelética relacionada com o trabalho e características dos trabalhadores de cervejaria no sudoeste da Nigéria - Um estudo-piloto / Work-related musculoskeletal pain and characteristics of brewery workers in southwest Nigeria- a pilot study

A dor osteoarticular relacionada ao trabalho (DORT) é um sintoma comum associado a perturbações musculoesqueléticas relacionadas com o trabalho. É agravada por más técnicas de elevação, ergonomia inadequada, movimentos repetitivos e postura incômoda durante o exercício das suas funções. Variáveis como a idade, o estado civil, a experiência profissional, o álcool, o tabagismo e os hábitos de exercício têm desempenhado um papel importante na prevalência das DORT entre as diferentes categorias de trabalhadores. OBJETIVOS: este estudo centrou-se na prevalência ao longo da vida, de 12 meses e pontos das WMSP em associação com as características sociodemográficas, de estilo de vida e de trabalho dos trabalhadores da indústria cervejeira no Estado de Osun, sudoeste, Nigéria. MÉTODO: um design de pesquisa descritiva foi utilizado, e um total de oitenta e nove (89) participantes foram recrutados com estrita adesão aos critérios de inclusão. Foi desenvolvido um questionário de 28 itens para obter informações específicas sobre a prevalência e o padrão de DORT, enquanto medições antropométricas (peso e altura) de cada participante foram medidas. Os dados coletados foram organizados e analisados usando estatísticas descritivas e teste de Qui quadrado. RESULTADOS: A prevalência de DORT ao longo da vida, 12 meses e pontos entre os participantes foi de 96,6%, 93,3% e 57,3%, respectivamente. As costas baixas eram a região corporal mais afetada. Existem associações significativas entre cada uma das idades, a prevalência de 12 meses e pontos das DORT e o estado civil dos participantes. Além disso, existe uma associação significativa entre a prevalência pontual de DORT e a idade dos participantes. CONCLUSÃO: concluiu-se que havia uma elevada prevalência de DORT entre os trabalhadores da cervejaria no Estado de Osun, sudoeste, Nigéria.

Work-related musculoskeletal pain (WMSP) is a common symptom associated with workrelated musculoskeletal disorders. It is aggravated by poor lifting techniques, inappropriate ergonomics, repetitive movements and awkward posture during the course of performing one's duties. Variables such as age, marital status, work experience, alcohol, smoking and exercise habits have been found to play major roles in WMSP prevalence among different categories of workers. OBJECTIVES: This study focused on the lifetime, 12-month and point prevalence of WMSP in association with the socio-demographics, lifestyle and work-related characteristics of brewery workers in Osun state, Southwest, Nigeria. METHOD: A descriptive research design was utilized, and a total of eightynine (89) participants were recruited with strict adherence to the inclusion criteria. A 28-item questionnaire was developed to obtain specific information on the prevalence and pattern of WMSP, while anthropometric measurements (weight and height) of each participant were measured. Collected data were organized and analyzed using descriptive statistics and Chi square test. RESULTS: The lifetime, 12-month and point prevalence of WMSP among the participants were 96.6%, 93.3%, and 57.3% respectively. The low back was the mostly affected body region. Significant associations exist between each of the lifetime, 12-month and point prevalence of WMSP and participants' marital status. Furthermore, a significant association exists between the point prevalence of WMSP and participants' age. CONCLUSION: It was concluded that there was a high prevalence of WMSP among brewery workers in Osun state, Southwest, Nigeria.

Study of Work-Related Musculoskeletal Pain and Health-related Quality of Life among Hospital Workers

PURPOSE: This study examined the work-related musculoskeletal pain and quality of life of hospital workers.METHODS: Self-reported questionnaires were sent to 350 hospital workers at Seoul and Gyeonggi-do, of which 341 were returned. The questionnaire had four items that covered the demographic information, areas of musculoskeletal problems, pain rating scale, and quality of life. The analysis was completed using descriptive statistic, and the differences between pain and demographic variables were identified using a chi-square test. The differences between the type of occupation and quality of life were analyzed by one-way analysis of variance and a Kruskal-Wallis test.RESULTS: The 12-month prevalence of work-related musculoskeletal pain was 86.1% of physical therapists, 86.5% of occupational therapists, 77.1% of dental hygienists, and 75.8% of nurses. A significant difference in the general and work related variables was observed between the subject with a physical burden and type of occupation. The most affected pain sites of the physical therapist included low back, hand and wrist, shoulder, and neck. The occupational therapists included the hand and wrist, shoulder, neck, but the nurses and dental hygienists reported the shoulder, back, hand and wrist. A significant difference in the quality of life was noted between the subjects in physical therapists and dental hygienists and the subjects in the nurses and occupational therapists (p=0.00).CONCLUSION: These findings show that hospital workers appear to be high risk for work-related musculoskeletal pain, and the quality of life of physical therapists and nurses was higher than that of dental hygienists and occupational therapists.

Change in Musculoskeletal Pain in Patients With Work-Related Musculoskeletal Disorder After Tailored Rehabilitation Education: A One-Year Follow-Up Survey

OBJECTIVE: To apply tailored rehabilitation education to video display terminal (VDT) workers with musculoskeletal pain and to assess changes in musculoskeletal pain after rehabilitation education. METHODS: A total of 8,828 VDT workers were screened for musculoskeletal disorders using a self-report questionnaire. Six hundred twenty-six VDT workers selected based on their questionnaires were enrolled in musculoskeletal rehabilitation education, which consisted of education on VDT syndrome and confirmed diseases, exercise therapy including self-stretching and strengthening, and posture correction. One year later, a follow-up screening survey was performed on 316 VDT workers, and the results were compared with the previous data. RESULTS: Compared with the initial survey, pain intensity was significantly decreased in the neck area; pain duration and frequency were significantly decreased in the low back area; and pain duration, intensity, and frequency were significantly decreased in the shoulder and wrist after tailored rehabilitation education. In addition, pain duration, intensity, and frequency showed a greater significant decrease after tailored rehabilitation education in the mild pain group than in the severe pain group. CONCLUSIONS: This study found that work-related musculoskeletal pain was reduced after tailored rehabilitation education, especially in the shoulder, wrist, and low back.
