Ergonomics Assessment and Work-Related Musculoskeletal Disorders in Construction Workers

BACKGROUND Millions of worker are being affected by work related musculoskeletal disorders (WRMSDs) every year. (1) WRMSDs occur due to repetitive motions, heavy lifting and awkward working position like bending, twisting and kneeling. The purpose of this study is to determine significant association between posture risk level and prevelance of work related MSDs. METHODS It is a associational study was conduct in raiwand road and Multan road. We collect data through VAS, Nordic questioner and RULA assessment sheet. We collect data from 195-construction worker, participants chi square test was used to check significant of the study, and p value of 0.021 was considered. RESULTS Mean value of VAS to be found was 1.39.489 SD, mean value of BMI to be found was 1.98.436 SD, mean value of age to be found was 2.64.927 SD and mean value of final score of RULA to be found 6.62.488 SD. There was significant association between posture risk level and prevelance of low backache in construction workers as p value was 0.021. Low backache was found most prevalent in construction workers with frequency of 181 (92.8 %). CONCLUSION There was significant association between posture risk level and prevelance of low backache in construction workers. Low backache was found most prevalent in construction workers. Score of RULA indicated that further investigation and changes immediately were required ergonomically
