Table 2 Time course changes of detailed LBP VAS scores

From: Characteristics of relief and residual low back pain after discectomy in patients with lumbar disc herniation: analysis using a detailed visual analog scale

LBP Before surgery 3 months after surgery 6 months after surgery 1 year after surgery
in motion 62.8 (29.9)* 15.5 (20.1) 12.5 (18.2) 13.2 (19.5)
while standing 61.6 (31.6) 12.7 (16.7) 11.9 (16.5) 13.8 (18.9)
while sitting 56.6 (32.9) 14.8 (19.2) 13.8 (18.5) 17.3 (22.0)†
  1. Reported as mean (SD)
  2. * Significantly higher than LBP in sitting (paired t-test, t(64) = 1.997, p = 0.025)
  3. † Significantly higher than LBP in in motion (paired t-test, t(64) = 2.200, p = 0.015)
