Standing work and low back pain: An experimental analysis of risk factors

Time had a significant effect on increases in low back pain relative to baseline (T0 = 1.71, SE = 0.34). The estimated increases in low back pain from baseline were 1.41 at (T1), 2.38 at (T2), 3.07 at (T3), and 3.66 at (T4), all of which were statistically significant (p < 0.001).ConclusionsLow back pain intensity increased significantly and similarly across all experimental scenarios, regardless of the combination of factors evaluated (posture, surface, or insole use). The results indicate that low back pain, as the starting point of clinical pain perception (≥ 9 mm VAS), manifests itself after 60 min of standing, regardless of the combined study factors.
