Figure 2: The changes in various parameters across pre- and posttest time points for null and active experiments in the spinal cord injury + neuropathic pain study group (n = 10). Parameters displayed include (a) VAS: Visual analog scale, (b) SDNN: Standard deviation in N–N intervals, (c) NN50: Pairs of successive R–R beat lengths varying by >50 m s, and (d) pNN50: Proportion of NN50 for total number of pNN50. Standard error bars are shown; asterisks denote statistically significant differences
