(A) Neurite growth of DRGs (L4-L6) isolated 1 day after ES is not enhanced (n=6, t-test p=0.68, mean ± SEM). DRGs (L4-L6) isolated (B) 7 days after a single 7h stimulation or (C) after daily 1h stimulations for 7 days show significantly increased neurite growth (n=5–8, t-test *p<0.05; mean ± SEM), but the effect size is similar to single 1h stimulation (compare to Fig.2). (D) For repeated stimulations (n=7, ANOVA p<0.01, Dunnett’s multi comparison test, *p<0.05), motor thresholds were determined on a daily basis, noticing a significant increase in the first 2 days post-surgery, with a return to baseline at later time points.
