This technique can be used to determine the approximate number of motor neurons in a muscle or group of muscles.Objective:To test the MUNE values according to subject’s gender and hand dominancy in the normal population.Methods:Healthy volunteers who had neither neuromuscular nor systemic/ metabolic disease, with normal neurological examination were studied. Ninety hands of 56 healthy volunteers (11 males and 45 females) with ages ranging from (24-58) years were included in the study. All had normal median nerve conduction studies. Manual incremental (INC) method and adapted multiple points stimulation (AMPS) method were performed for MUNE.Results:Gender did not have an effect on the scores according to the two studied methods (p=0.054 by INC method and p= 0.700 by AMPS method). Hand dominancy also show no statistically significant difference of the scores of MUNE according to both studied methods (p=0.091) by INC method and (p=0.051) by AMPS method.Conclusion:Incremental stimulation and adapted multiple point stimulation are reliable and easily applicable methods with same reproducibility in estimating motor units with no significant effect for subject gender or hand dominancy.Keywords:Motor unit, motor unit number estimation (MUNE), incremental stimulation (INC) method, adapted multiple point stimulation (AMPS) methodCitation:Abdul Muneem SD, Kaddori HG.
