Introduction: Dentistry is a high risk profession for developing MSDs (musculoskeletal disorders) because of the high visual demands, prolonged static posture, repetitive motion, inadequate lighting and mental stress that result in prolonged and affixed as well as uncomfortable postures. Aim of Work: To study the occurrence of MSDs among dentists in comparison to physician at Minia University Hospitals. Materials and methods: A cross-sectional study was conducted among 328 participants; 164 dental and 164 medical practitioners recruited, interviewed and examined during the period from February, 2015 to December, 2015. Every participant completed a questionnaire that included his socio-demographic data, full occupational history and lifestyle factors as well as information about any job-related MSDs. Describing and determining the site of pain was performed by using the Modified Standard Nordic Musculoskeletal Questionnaire (NMQ), while the severity of pain was assessed by using the Visual Analog Scale (VAS). Results: However, both the dentist and physician groups were matched regarding their age and sex, MSDs were significantly higher among dentists (88.4%) than physician (58.5%), (p=0.001), (OR=5.4). Neck (63.4%), low back (54.3%), shoulder (53%), wrist (49.4%) and upper back (44.5%) were the most common MSDs among dentists. The most common factors that lead to the occurrence of MSDs were prolonged static posture, long duration of employment and increased work load and working hours. Conclusion: MSDs are much higher among dentists than physicians. Neck and low back are the most common sites of MSDs among dental personnel. MSDs risk factors include prolonged static posture, long duration of employment and increased work load and working hours.

Introduction: Occupational use of computers has increased rapidly over recent decades, and has been linked with various musculoskeletal complaints.Repetitive hand movements lead to overload of the upper extremity and neck, and prolonged sitting posture leads to overload on the lower back. Pain in the upper extremities and the neckshoulder region will affect the workers' health and productivity and it accounts for most work-related time lost. Aim of work: To identify the prevalence of musculoskeletal symptoms and associated risk factors among computer office workers in Minia University. Materials and Methods: This is a descriptive cross-sectional study; a total of 182 computer office workers in Minia University were interviewed during the period from January to June 2016. Every participant completed a questionnaire that included his socio-demographic data, and information about any job-related musculoskeletal disorders. Describing and determining the site of pain was performed by using the Maastricht Upper Extremity Questionnaire (MUEQ). Results: The prevalence of musculoskeletal complaints was arranged in the following order: lower back pain (78%), neck complaints (68.1%) and upper musculoskeletal complaints (61.5%). There were significant associations between doing repetitive tasks, and not taking breaks on the one hand and lower back pain complaint on the other hand (p<0.001and 0.03, respectively). Conclusion: a high prevalence of musculoskeletal complaints was observed among computer office workers due to poor ergonomic practices in their workplace, being in the same position for long period, doing repetitive tasks and lack of regular breaks. The use of ergonomic principles will reduce these types of pain.
