Recovery of electromyographic (EMG) activity following TRF ablation, CRF ablation or transection of the sciatic nerve. (A) Average gastrocnemius muscle EMG activity for 10–12 rats (per group per timepoint) during a 12-week period after ablation of the sciatic nerve using TRF (dark gray line), CRF (black line), or transection (light gray line). EMG activity is significantly reduced from pretreatment baseline (dotted line) at 1-week post-treatment in all groups. However, the CRF ablation group has significantly lower EMG activity compared with the TRF group, for up to 6 weeks postablation. Each point represents the mean±SEM, *p<0.05. (B) Average tibialis anterior (TA) muscle EMG activity for 10–12 rats (per group per timepoint) during a 12-week period after ablation of the sciatic nerve using TRF (dark gray line), CRF (black line) or transection (light gray line). EMG activity is significantly reduced from pretreatment baseline (dotted line) at 1-week post-treatment in all groups, however, even in the TA the CRF ablation group has significantly lower EMG activity compared with the TRF group for up to 6 weeks postablation. Each point represents the mean±SEM, *p<0.05. RF, radiofrequency; SEM, SE of mean.
