The present study was performed to determine the pathways of peripheral afferentnerve inputs that influence the aetivities of the motor cortex by the examining the effeet of vibration on the motor cortex excitability in the patients with stroke and normal healthy control. We examined eight healthy control and eight patients with stroke. Excluding capsular infaretion (in whom there was a higher threshold), a signifıcant lower threshold was found cortical stroke patients. in the involved hemisphere, mean onset latency was shorter during 30 Hz vibration whereas latency was not changed by the 130 Hz vibration. in the second examination, onset latency were not changed both 30 Hz and 130 Hz vibrations. in the intaet hemisphere any change was not observed by low frequency vibration but signifıcant shorted by high frequency vibration. There were a clear augmentation on the amplitude in patients and healthy control during low and highvibrations. But, in the healthy control group was found to influence profoundly the amplitude of elicited by vibration. Appreciate of the sensorial inputs that any future therapies aimed atreorganized within motor cortex after stroke, and give new insight both into mechanisms of funetional recovery and potential therapies for neuro-rehabilitation.

Keywords: Stroke, motor cortex, transcranial magnetic stimulation, vibration, plasticity.
