Fig. 2 — a The average abdominal pain scores (± SEM) from visual analog scale (VAS) with 0 indicting no pain and 10 indicating severe pain are shown at baseline, 6 months, and at the last patient visit after SCS implantation (last visit). Abdominal pain scores decreased significantly at 6 months and at the last patient visit compared with baseline (p < 0.001) (n = 23). b Bar graph showing average abdominal pain scores in the high frequency spinal cord stimulators (10 kHz-SCS) group (n = 12) and the traditional low frequency spinal cord stimulators (Trad-SCS) group (n = 11). Abdominal pain decreased more in the 10 kHz-SCS group, but not statistically significant when compared with Trad-SCS group at 6 months and most recent visit (last visit) (p > 0.2)
