In this paper an coupled Burgers' equation is considered and then a method entitled interval finite-difference method is introduced to find the approximate interval solution of interval model in level wise cases. Finally for more illustration, the convergence theorem is confirmed and a numerical example is solved.

BackgroundShort-interval intracortical inhibition (SICI), as measured by threshold-tracking a function of inter-stimulus interval (ISI), has been proposed useful biomarker for amyotrophic lateral sclerosis (ALS), but its relationship to conventional amplitude measurements not established.MethodsSerial tracking SICI at increasing ISIs from 1 7 ms (T-SICIs) was compared in 50 healthy control subj...
