There have been no studies reported on the difference in cortical activation during use of volar and dorsal hand *** attempted to investigate the difference in cortical activation in the somatosensory cortical area during use of volar and dorsal hand splints by functional magnetic resonance imaging（f MRI）.We recruited eight healthy volunteers.f MRI was performed while subjects who were fitted with volar or dorsal hand splints performed grasp-release *** of interest were placed on the primary motor cortex（M1）,primary somatosensory cortex（S1）,posterior parietal cortex（PPC）,and secondary somatosensory cortex（S2）.Results of group analysis of f MRI data showed that the total numbers of activated voxels in all ROIs were significantly higher during use of volar hand splint（3,376） compared with that（1,416） during use of dorsal hand *** each ROI,use of volar hand splint induced greater activation in all ROIs（M1：1,748,S1 ：1,455,PPC：23,and S2：150） compared with use of dorsal hand splint（M1：783,S1：625,PPC：0,and S2：8）.The peak activated value was also higher during use of volar hand splint（t-value：17.29） compared with that during use of dorsal hand splint（t-value：13.11）.Taken together,use of volar hand splint induced greater cortical activation relevant to somatosensory function than use of dorsal hand *** result would be important for the physiatrist and therapist to apply appropriate somatosensory input in patients with brain injury.

The corticospinal tract （CST） is a neural tract responsible for motor function in the human brain. It is mainly related to hand movements （Iang, 2014）. Therefore, recovery of an injured CST contributes to good recovery in stroke patients and a thorough knowledge of the recovery mechanism regarding an injured CST is required for successful brain rehabilitation.

The corticospinal tract （CST） is a major neural tract for mo- tor function in the human brain. In addition, CST is mainly concerned with execution of movement of the hand （jang, 2014）. However, few studies are reported on the mecha- nism underlying CST recovery after traumatic brain injury （Seo and jang, 2015）. In this study, we report on a case that showed recovery of an injured CST by traumatic axonal injury （TAI） at subcortical white matter, as detected on fol- low-up diffusion tensor tractography （DTT）.
