Abstract:
Objective To study the effects of constraint-induced movement train (CIMT) on the neurological medullary sheath in the rats after middle cerebral artery occlusion (MCAO). Methods 55 SD rats were randomly divided into CIMT group and nature recovery (NR) group after MCAO. The CIMT group were trained with balance beam and rolling cage everyday, with restrictting the movement of the intact upper limbs. The NR group lived in the same condition. The rats in CIMT group were assessed with ethology 5 d, 10 d, 15 d, 30 d and 60 d after operation respectively. At last, 5 rats of each group were checked with MRI, then they were immolated for myelin staining. Results The balance and muscle strength of CIMT group improved better compared with the NR ones (P<0.05), as well as the diameter and the demyelination of neurofibril in the infarcted area. Conclusion CIMT can collect more functional neurofibra and decrease myelinolysis.
