Detailed kinematic analyses of hindlimb motor performance on a treadmill before and after re-transection. Detailed kinematic analyses of hindlimb motor performance on a treadmill before and after re-transection were performed and analyzed using a robotic device (Rodent Robot 3000; Robomedica Inc.). BT represents before re-transection; AT represents after re-transection. Although none of the step parameters in the control group showed significant changes, the step cycle area parameters were attenuated in the SM-345431 group after re-transection. Further attenuation of the step ability parameters was observed in the combined treatment group after re-transection. *P < 0.05 **P < 0.01. Statistical analyses were performed using t-test analyses. Data are presented as the mean ± S.E.M.
