Prevalence, Cause, and Prevention of Muscle Strain and Fatigue among Physical Therapists in Al Zawiya City: A Cross-sectional Study

Abstract

 Physical therapists, by virtue of their clinical practical requirements, exhibit heightened vulnerability to occupational hazards, most notably musculoskeletal disorders (MSDs). While we previously established that muscle strain and fatigue are the most prevalent conditions among physical therapists, a comprehensive understanding of their incidence and specific occupational triggers remains essential. This paper addresses this gap by analyzing the underlying causes and establishing preventive measures to mitigate these risks. A cross-sectional study was designed with a self-administered questionnaire. 46 participants out of 62 total respondents who reported a muscle strain and fatigue were recruited from different physical-therapy clinics in Al Zawiya city 74.2%. Performing manual therapy for a long time was the most common activity associated with the injury (39.1%). Furthermore, stopping work when experiencing symptoms had the highest percentage (23.9%) to avoid future injury. Younger physical therapists (under 30 years) were more likely to take rest breaks and stop working when experiencing symptoms (19.6%), while older therapists (over 30 years) were more inclined to change work schedules (8.7%). More experienced physical therapists were more likely to take rest breaks and change work schedules (15.2%), while less experienced therapists were more likely to stop working when hurt or when symptoms occur (10.9%). Muscle strain and fatigue are prevalent occupational hazards among physical therapists; moreover, specific work-related factors, such as prolonged manual therapy, sudden patient movements, lifting, and prolonged static postures, contribute significantly to the risk of muscle strain and fatigue.
