Evaluation of occupational and non-occupational risk factors associated with carpal tunnel syndrome-related symptoms in office workers

Abstract

Background : While the main occupational and non-occupational risk factors associated with carpal tunnel syndrome are known, we still need to understand which of these factors has a stronger correlation with carpal tunnel-related symptoms in office workers and to improve future work-space recommendations accordingly. Objective : This study aimed to investigate the relationship between occupational and non-occupational risk factors and carpal tunnel syndrome-related symptoms among office workers who use a computer in their dayto-day activities. Methods : The data used in this study were collected from May to September 2022 through an online questionnaire from one respondent to another through different forms of social media, using the snowball method. The recorded data were further analysed using an SPSS program. In this way, we analysed quantitative variables by calculating the means, the medians, the standard deviation and the normal distribution and qualitative variables by reporting them as absolute values and percentages of the total. We compared different subgroups of samples using the chi-square test and the binary regression method. A p-value of less than 0.05 was the threshold of statistical significance. Results : This study evaluated 130 office workers and identified and analysed the complex relationships between occupational and non-occupational risk factors of CTS and CTS symptoms grouped as pain, sensory function impairment and motor function impairment. Through data analysis and further logistic regression analysis, we concluded that while sensory function impairment is mostly associated with occupational factors such as computer typing with one hand, pain and motor function impairment are associated with both non-occupational, well-known risk factors (female sex, high BMI) and number of hours on the computer outside of work, and occupational risk factors like using both a mouse and an external keyboard, having a chair with adequate arm support and typing with one hand. Conclusion : Both occupational and non-occupational risk factors contribute to the development of CTS-related symptoms. Our dataset highlights the complex relationship between CTS occupational and non-occupational risk factors in office workers, thus providing insights for future workplace recommendations and preventive strategies.
