Fig. 5. Efficacy of GTB and GTO after 6 and 12 weeks of therapy.
A: The total episodes in GTB declined dramatically from the beginning to the end of 6 and 12 weeks after biofeedback therapy (P = 0.001), while there are no significant differences in GTO (6 weeks, P = 0.998. 12 weeks, P = 0.970). B: The duration in GTB has significant difference between 6 and 12 weeks after biofeedback therapy compared to baseline (6 weeks, P = 0.026, 12wks, P = 0.012), while similar results cannot be found in GTO (P = 0.999).
