Changes in Lumbar Disk Morphology Associated With Prolonged Sitting Assessed by Magnetic Resonance Imaging

Analysis of the data shows that the greatest change in disk height is at the L4-5 level after prolonged sitting without intermittent breaks. The other levels did not show a significant change in their height. The findings also showed that the L4-5 height changes were not significant with brief positional changes every 15 minutes. Fewer changes in disk height may correlate with an improvement in low back pain and disability.
