For this purpose, training programs and corrective exercises were employed in four one-hour sessions in one week and 16 one-hour sessions in eight weeks.</span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:150%"><b><span style="font-size:10.0pt"><span style="line-height:150%"><span style="color:black">Results:</span></span></span></b><span style="font-size:10.0pt"><span style="line-height:150%"><span style="color:black"> Musculoskeletal disorder prevalence, postures, and workplace layouts were assessed using the Nordic Questionnaire and a researcher-made checklist. Accordingly, the highest prevalence was observed in the lower back (63.2%), neck (52.6%), and knees (42.1%). Differences in the rates of proper postures and workplace layouts were statistically significant before and after the ergonomic training so that 81.25% of postures and 47.8% of workplace layouts were improved. The results showed that training programs on ergonomics principles and corrective movements reduced musculoskeletal disorders among office computer users within the range of 10.5 to 52.6%. </span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:150%"><b><span style="font-size:10.0pt"><span style="line-height:150%"><span style="color:black">Conclusions:</span></span></span></b><span style="font-size:10.0pt"><span style="line-height:150%"><span style="color:black"> Increasing employee awareness of appropriate postures, workplace layouts, and corrective movements effectively reduced musculoskeletal disorders in computer users.</span></span></span></span></span></span></div> Training,Ergonomics,Exercise,Posture,Computer,Musculoskeletal, 246 255 http://johe.rums.ac.ir/browse.php?a_code=A-10-496-2&slc_lang=en&sid=1 Seyedeh Farimah Navidi farimah.navidi@gmail.com 22400319475328460011417 22400319475328460011417 No M.Sc in Occupational Health Engineering, Faculty of Health, Student Research Committee, Qazvin University of Medical Sciences, Qazvin, Iran.
