INTRODUCTION - Low back pain is an epidemic of modern times, and leads among the health problems of the musculoskeletal system. Pain in a large number of cases prevents people from performing daily life activities. Sick leave represents a financial burden for the patient and for the employer, but also burdens the health system with increased costs of treatment and rehabilitation. RESPONDENTS AND METHODS - The study included 130 subjects, of which 76 physiotherapists and 54 nurses/ technicians of all levels of education. Respondents completed an online survey questionnaire asking general sociodemographic questions, and if they suffered from low back pain, they completed two standardized questionnaires Oswestry Disabillity Index (ODI) and Roland-Morris Disabillity Questionnarie (RMDQ). The survey was conducted during April, May and June 2023. RESULTS - Statistical analysis showed that among the examined groups there is a high rate of reported low back pain in more than 70% of cases. There is no significant difference in the incidence of low back pain between physiotherapists and Nurses/Technicians. The majority of respondents are female, nurses/technicians are statistically older and have longer working experience than the physiotherapist population, while physiotherapists statistically completed a higher level of education. Neither the ODI questionnaire nor the RMDQ have a statistically significant difference in disability between nurses/technicians and physiotherapists. DISCUSSION - Other studies also show a high prevalence of low back pain in both groups of medical professionals, the similarity of data related to age, gender and length of service gives us the opportunity to compare data with those obtained in the study conducted on nurses / technicians and physiotherapists in the Republic of Croatia. CONCLUSION - The study found that a large number of examined medical workers encounter low back pain, but there are no large statistically significant differences between the groups. In future studies, it is necessary to work on the homogeneity of the subjects, and on the concretization of certain aspects of the research.
