Figure 13. Percentage reduction (≥30% responder rate) in overall VAS score at week 24 from
baseline
Data for paresthesia coverage at both 12 and 24 weeks were available for 73 subjects. More than
half of the subjects (45 out of 73 [61.6%]) were paresthesia-free using burst stimulation, while
only 2 subjects (2.7%) were paresthesia-free using tonic stimulation. In addition, 89.0% of
subjects (65/73) experienced a reduction in paresthesia or no paresthesia with burst stimulation
compared to tonic stimulation. The following table summarizes these results.
