Abstract Background: Pan American Health Organization cited low back pain as one of three occupational problems that should be under surveillance, despite a high prevalence of low back pain (LBP) development during prolonged standing. Objectives: to investigate the effect of seated break time on prolonged standing low back pain developers. Methods: 60 subjects participated in this study. They were randomly distributed into two equal groups; group I involved 30 subjects where stand for 15 min. and sit for 5 min. group II involved 30 subjects where stand for 30min and sit 10 min throughout the workday for 8 hours. The study is one shot study. The VAS to measure (pain) & BROM to measure (flexion and extension of thoracic and lumbar ROM).Results: There was no significant improvement in stand to sit ratio of 3:1 which did not allow for complete and lasting recovery of LBP developed in response to prolonged standing. low back pain developers (LBPD) utilized a limited range of their lumbar spine angle and demonstrated increased lumbar spine extension and thoracic flexion. Conclusions: Prolonged standing in the workplace has the potential to result in LBP for workers |
