Effect of Nonsurgical Spinal Decompression on Intensity of Pain and Herniated Disc Volume in Subacute Lumbar Herniated Disc

Figure 4

Changes in visual analog scale (VAS) scores of lower back pain (a) and lower leg pain intensity (b) between group D and group N Both groups showed a decrease in lower back pain intensity from baseline to 3 months (). However, lower back pain intensity was not significantly different between the groups at any time. The lower leg pain intensity showed a significant decrease in VAS scores from baseline to 3 months (), and the lower leg pain intensity in group D showed a significantly lower VAS score than that in group N at 2 months (). The error bar indicates the standard deviation. Significant at when compared to the baseline VAS score. Significant at between D and N groups.
