Background: Stroke has always been a complicated disease which affects not only the patient quality of life but also the patient family. In ischemic stroke patients, one of the most complicated outcomes was the disruption of motor function. Increased motor function is a visible positive outcome of stroke patients.

Aim: This study aims to measure the motor evoked potentials values which the results might give us more insights into how this disease affects the motor neuron pathway.

Methods: This study was an experimental pre-posttest study involved 75 patients diagnosed with chronic ischemic stroke (onset of more than 30 days). The MEPs value was measured by adjusting the IAHF procedure in 2015.

Results: There was no significant difference between motor evoked potential value (amplitude, latency, central motor conduction time) pre and post intraarterial heparin procedure (IAHF) (p>0.05). Occasionally, there was a significant difference in latency value in lacunar, subcortical, and cortical-subcortical area after IAHF (p<0.05).

Conclusion: This study shows that the size and localization of the affected area might determine the results of IAHF.
