Introduction: The Covid-19 pandemic has forced people to increase the amount of work done at home. Working at home has presented with numerous advantages and disadvantages, among which environmental factors play an important role. When designing a home office, it is crucial to follow the principles of ergonomics as it is the only way to reduce the risks of musculoskeletal disorders. Occupational therapists advise and help people in designing an ergonomic environment and using ergonomic aids. Purpose: The purpose of this thesis was to demonstrate the appropriate orderliness of the workplace when working behind a computer screen at home. We tried to determine the loads and biomechanical body postures, and whether muscle discomfort appeared. Methods: A qualitative approach was chosen for this study. By means of purposive sampling, we chose 25 participants who were working for home during the Covid-19 pandemic and were using a computer. The RULA method was used to assess the physical load, the Nordic Body Map for assessing muscle discomfort, and a Questionnaire on Factors of the Working Environment to assess the orderliness of the work environment. One month after the occupational therapy intervention, which included education, analysis, and counselling for adjustment, we repeated the assessment with all assessment forms that were mentioned. Results: The statistical analysis with a paired t-test showed a statistically significant difference between the initial and the final assessment as all participants either improved or maintained the same order of the workplace. When looking for links between muscular discomfort and incorrect posture, no statistically significant associations emerged. Discussion and conclusion: Education and health promotion as key factors in raising awareness of the importance of environmental factors proved to be important in our study as well as in foreign studies. Alongside education, workplace ergonomics, interventions to reduce sedentary behaviour, and future use of mobile applications have an important role as well. Occupational therapy intervention has proven to be helpful in designing an ergonomically appropriate arrangement and in maintaining muscle comfort while working on a computer. It would make sense to transfer this into the existing occupational therapy practice. Similar studies should be repeated on a larger sample in the future.
