However, many studies which are used the implantation device use this model for observing the axon regeneration. The opening of dura is the necessary for this model and a sharp penetrating force penetrates into the spinal cord for cutting some or all spinal cord \cite{rosenzweig2004}. Normally, the lateral hemisection or dorsal hemisection is preferred than full transection. Because the function of bladder and bowel are sufficiently preserved. Then, the post-operative care is easier than full transection model and the survival rate is increased. In dorsal hemisection procedure, the major components of the corticospinal tract, the dorsal column, and rubrospinal tract are damaged leading to the impairment of the paw placement during walking and overground locomotion. Therefore, the accuracy, strength, and velocity in left and right hindlimbs are affected
