        abstract = {Background: Musculoskeletal disorders that occur because of work have been identified as a serious health risk in the workplace. Musculoskeletal disorders were strongly linked to working long hours.  Prevalence of low back pain in industrial workers is 62%. Logistic regression revealed that low back discomfort was statistically significantly associated with age, the type of occupation, the number of hours worked, improper body mechanics, frequent bending or twisting, and extended sitting. Patients with low back pain may have weaker lower limb muscles compared to healthy controls.
Materials and Methods: 91 young adults (age: 30-45yrs, male: 91) with low back pain and long-standing occupation (hours: 9±5) were assessed. Isometric muscle strength was measured using Baseline Hydraulic Hand-Held Dynamometer. Statistical analysis of reliability and validity comprised intraclass correlation coefficients (ICC) and Pearson correlations using GraphPad Prism software.
Results: In the study it was found that the Correlational graph between Hours of standing and MODQ score shows that as Hours of standing increases, MODQ score increases which means the data points have a positive association [r value (CI): 0.7850, P value: <0.0001]. Correlational graph between Hours of standing and individual lower limb muscle strength shows that the data do not have any association.
Conclusion: This study shows that as hours of standing increases, the MODQ score also increases. This proves that there is a correlation between hours of standing and low back pain. 
This study also shows that there is no correlation between Hours of standing and lower limb muscle strength of both the lower limbs of the following muscles- Hip flexor, Hip extensor, Hip abductor, Hip adductor, Hip MR, Hip LR, Knee flexor, Knee extensor, Ankle PF, Ankle DF.},
