Abstract:
ObjectiveTo identify the finding of functional MRI(fMRI) during active and passive fingers moving in hemipegic patients after stroke.Methods23 stroke patients with hemipegia were asked to actively moving their fingers and then passively moving with others' help.MSEPI technique was performed with planar parallel AC-PC.During each scan series,they were asked to perform repetitive finger-thumb opposition movement in the same period of active and rest.All the scanning data was transferred to a workstation and dealt with statistical method.Some patients examined fMRI again after rehabilitation.ResultsfMRI showed normal in the healthy side,with the decrease or displacement in the affected side of motor cortex area.Motor cortex area in the affected side would be recovered after rehabilitation.ConclusionfMRI can be used to evaluate the difference between active and passive moving motor cortex,and help to judge the prognosis of the patients with motor functional disorder.
