تجزیه و تحلیل ارگونومیک برای مطالعه شدت اختلالات اسکلتی عضلانی در میان دندانپزشکان هند

Throughout the world background literature reviews have shown a high prevalence of musculoskeletal disorders (MSDs) among dental practitioners. Prevalence of MSDs among dental practitioners in India is not well documented. Aim of this study is to determine the prevalence and distribution of MSDs among dental practitioners in Pune city in the state of Maharashtra, India. A cross sectional descriptive study in which a self-administered questionnaire (Body part discomfort survey) was used to assess the musculoskeletal symptoms among dental practitioners. In this study (n=57) in total, 47% of the respondents were males and 52% were females. The recorded data was analyzed. This questionnaire results (for all body parts), showed neck trouble to be the most predominant MSDs (69%), followed by shoulder (51%), upper back (51%), and lower back problem (39%).This results suggest that there is a need for change of body posture. This mean can be achieved by using a proper body support or change in work area. A prototype design is suggested to overcome this problem. The deployment of the prototype has reduced the RULA scoring and proved by t-test calculation. Results were verified by using the p-chart. The fraction of defects for all 12 areas and each respondent were calculated for further study.
