This study evaluates the effectiveness of stochastic resonance electric stimulation on neuromuscular control and proprioception in healthy and individuals with stroke.
Stroke is one of the leading causes of motor disability. The main intervention strategy in stroke rehabilitation is to induce cortical plasticity for motor re-learning. It has been demonstrated that electrical stimulation applied to the periphery can elicit abundant sensory afferent inputs to enhance excitability and activation area in the sensorimotor cortex. Recent evidence suggested that a new type of electrical stimulation pattern, stochastic resonance stimulation, is capable of efficiently enhancing the activation of peripheral and central nervous system. Therefore, the purpose of this study are to identify the effects of stochastic resonance electrical stimulation on neuromuscular control and proprioception, and to investigate the effectiveness of combining stochastic resonance electrical stimulation with rehabilitation program on post stroke motor function recovery.

stochastic resonance electrical stimulation is applied in the upper extremity during motor functional training. Sham comparator group uses sham stimulation - same electrode location, but no electrical current is applied during motor functional training

RECRUITINGEEG
we will calculate power spectral and see whether change in the alpha, beta, theta band
Time frame: baseline and one minute after stimulation
Fugl-Meyer Assessment for Upper Extremity
changes in upper extremity function of the stroke subjects
Time frame: baseline and one minute after stimulation
force deviation
we first calculated the absolute value of the difference between force output and the value of 50%MVC for each data point and then calculated the average force deviation value by dividing the sum of all values by the number of data points
Time frame: baseline and one minute after stimulation
joint angle
ABS(the subject perform degree - target degree )
Time frame: baseline and one minute after stimulation
muscle activation
EMG changes in stimulation
Time frame: baseline and one minute after stimulation
