Activity of daily living and motor evoked potentials in the subacute stroke patients

Objective:
To investigate the effectiveness of the daily living activity and motor evoked potential (MEP) in the subacute stroke patients.
Methods:
Nineteen subjects with subacute ischaemic/hemorrhagic stroke developed in the last three months were enrolled, and MEP was measured with transcranial magnetic stimulation. Functional Independence Measure (FIM) score were evaluated in both groups before and 4 weeks after comprehensive rehabilitative management. According to the presence of MEP response in the affected hemisphere, subjects were divided into MEP positive and negative group.
Results:
There was no significant difference between the two groups in age, sex, and post-onset duration. Four weeks later, the change in total FIM and self-care score improved significantly in the MEP-positive group, when compared to the MEP-negative group (p<0.05). However, cognitive improvement had no relationship with MEP responsiveness.
Conclusion:
We concluded that initial measurement of MEP is a useful assessment tool in predicting functional outcome of subacute stroke patients.
