ABSTRACT
Objective To evaluate the effect of the transcranial magnetic stimulation on upper-extremity function rehabilitation and changes in the excitability of cerebral cortex,and to evaluate from the viewpoint of electro-physiology the prognosis so as to guide the rehabilitation treatment of patients after stroke.Methods Forty-six patients in the early stage after a stroke were given TMS examinations of the ipsilateral brain region.Those with the motor evoked potentials (MEPs) amplitudes lower than 50 μV were classified into a motion-induced experimental negative group (the negative group),whiie those whose MEP amplitude reached 50 μV or more were classified as movement-induced positive (the positive group).Both groups were given the same treatment.Before and after 2,4 and 8 weeks of treatment the Fugl-Meyer movement function rating scale was used to assess their bilateral upper limb movement function.TMS technology was used to detect any change in the resting motor threshold (RMT) and the amplitude (Amp) of MEPs in the motor cortex.The incubation period of the cortex (CL) and the central motor conduction time (CMCT) in the contralateral motor cerebral cortex were also observed.Results After 4 weeks of treatment,the average score of the positive group on Fugl-Meyer upper movement function rating scale reached (54.99±2.76),significantly higher than before treatment and significantly higher than the negative group's average (P＜0.05).After 8 weeks of treatment,the average score in the positive group had increased further to 73.11±2.98,still significantly higher than that of the negative group (P＜0.01).After treatment,RMT decreased progressively in both groups,but that of the negative group dropped from (98.35±10.12) to (30.35±7.31) (9＜0.01),with significantly greater decline in amplitude and rate than that of the positive group (P＜0.05).After treatment,the Amp of both groups showed a gradual increasing trend.Amp increased earlier in the positive group,but there was no significant difference in the extent of the increase between the two groups (P＞0.05).After the treatment the CL and CMCT had shortened significantly in the negative group compared to before the treatment (P＜0.05),while there was no significant change in CL and CMCT after the treatment (P＞0.05).Conclusions The excitability of the contralateral motor cortex changes after a stroke.TMS can be used to characterize the MEP to monitor and predict recovery.This should help clinicians prepare more scientific rehabilitation plans.
ABSTRACT
@#ObjectiveTo observe occupational therapy combing with physical therapy on the upper limb movement function and the activities of daily living for the old stroke patient.Methods62 stroke patients with hemiplegia were divided into the observation group (occupational therapy with physical therapy) and control group (physical therapy). All patients were evaluated with Bathel Index (BI) and Fugl-Meyer Assessment (FMA) before and 3 months after treatment.ResultsThe scores of BI and FMA increased significantly in the observation group compared with the control group after the treatment (P<0.01).ConclusionOccupational therapy combing with physical therapy can obviously improve the upper limb movement function and the activities of daily living for the old stroke patient.
