E.P. Zehr, KOMIYAMA, T. and R.B. Stein. A Method for Functional Quantification of the Reflex Effect of Human Peripheral Nerve Stimulation. Adv. Exerc. Sports Physiol., Vol.6, No.1 pp25-32, 2000. We have developed simple method that accounts for the overrall function of reflex effects occurring in the surface electrimyogran (EMG) after human nerve stimulation. This method involves the subtraction of pre-stimulus EMG levels from EMG modulation curves obtained after human peripheral nerve stimulation. This subtraction yields a residual of purely reflex EMG which is cumulatively summerd from the end of the stimulus artifact until 150 ms post-stimulation. The sum is then divided by the duration of intergration to yield an index of the overall effect of stimulation: the Average Cumulative Reflex EMG at 150 ms post-stimulation (ACRE150). We tested the ACRW150 parameter in a variety of ways in order to verify the reflex origin of the value, its trial-to-trial reproducibility, and applicability to the study of functional reflex modulation in human subjects. The main application is in the quantification of the functional (ocerall) reflex effect of nerve stimulation.
