Work-related Musculoskeletal Disorders Among Physiotherapists and Physiotherapy Students in Croatia and their Association with Physical Fitness

INTRODUCTION: Among physiotherapists, work-related musculoskeletal disorders (WMSDs) are the most common health problem. This study aimed to provide evidence for planning evidence-based health promotion programmes for ensuring and maintaining adequate physical fitness (PF) to decrease WMSDs among physiotherapists which would have started already during the study. METHODS: A cross-sectional study involved the participation of a total of 100 physiotherapy students and 62 physiotherapists. Observed variables were prevalence of WMSDs in the last 12 months, lasting >3 days during physiotherapeutic activities and five PF components: body composition, cardiorespiratory and muscle endurance, muscle strength, and flexibility. A chi-square test and binary logistic regression were used as the main analytical methods. RESULTS: Prevalence of WMSDs in physiotherapists was 63.9% (the most common locations: lower back, shoulders, neck), while in physiotherapy students it was 46.5% (the most common locations: lower back, neck, upper back) (p=0.031). Among the PF components, the results showed statistically significantly worse flexibility among students compared to physiotherapists (about two thirds of students had poor or very poor results of flexibility testing) (p=0.002) in comparison to physiotherapists. A statistically significant positive association between WMSDs and PF was observed only between knee pain and poor cardiorespiratory endurance (OR=4.03 with 95% CI 1.12-14.58; p=0.033). CONCLUSION: The study showed poor flexibility among students indicating that it is necessary to direct them to perform activities that will increase the extensibility of muscles. The awareness of this problem should be increased. A specific role should be played by staff involved in clinical practice.
