A novel technique for managing symptomatic spinal cysts using epiduroscopic neural laser decompression: technical note and preliminary results

Table 2 Clinical outcomes of the study group

	Pre-operative scores	Post-operative scores	p value
Visual analog scale back pain	4.7 ± 0.7	1.8 ± 0.8	0.001
Visual analog scale leg pain	5.8 ± 1.2	1.6 ± 0.7	0.001
Oswentry Disability Index (%)	27.2 ± 10.7	14.6 ± 7.7	0.001

Differences between pre- and post-operative visual analog scale pain scores and Oswentry Disability Index scores (%) were compared non-parametrically using Wilcoxon ranked-sum tests (α = 0.05)
