Prevention of low back pain in office workers
Low back pain is the most common musculoskeletal complaint in sedentary office workers. One theory (ignoring psychosocial factors) is that tightening of the hip flexors and poor endurance of the trunk muscles, in particular the extensors, results in altered biomechanics of the pelvis and lumbar spine.
The current, prospective, randomised control trial study examined the effect of iliopsoas stretches and trunk endurance exercises on the incidence of low back pain in healthy office workers that were found to have reduced lumbar extension range of motion and reduced endurance of the major trunk muscles (erector spinae, transverse abdominis and quadratus lumborum).
The intervention group performed iliopsoas stretches twice daily in addition to trunk isometric contractions twice weekly. There was significantly lower incidence of low back pain in the intervention group. 9% of the intervention group and 20% of the control group complained of low back pain over a 1 year period.
