Functional evaluations of rat sciatic nerve after bridging defect with TENG. a Curve graph showing the SFI value, the motor function scores of rat hind limb, in 3 grafted groups and the non-grafted group at indicated time points within 12 weeks, and the non-grafted group was set as the control group. b Histogram showing the sensory function scores, the withdrawal response time of rat paw in the autograft, TENG, conduit, and non-grafted groups was all delayed at the 4th week and was reduced to different degree at the 12th week. c Representative CMAP recording image at 12th week after grafting by autograft, TENG, or conduit, and the contralateral uninjured side was set as the control group. Histograms showing CMAP amplitude and MCV evaluation at 12th week after grafting. n = 8; ***p < 0.001 compared with the uninjured group; ^#p < 0.05, ^##p < 0.01, ^###p < 0.001 compared with the autograft group; ^△p < 0.05 compared with the conduit group; ^§p < 0.05, ^§§p < 0.01 compared with the non-grafted group
