Effects of sitting posture and duration on lumbosacral nerve root function: A case-control study

).ConclusionVarious sitting postures and durations exert different effects on the lumbosacral spine and nerve roots. Slouched sitting reduces spinal stress and lower nerve root compression compared to erect and slumped seated positions. Extended sitting duration may partially compress the lumbosacral nerve root, thereby potentially contributing to postural low back pain over time.
