Background: Transcranial Magnetic Stimulation (TMS) is a non-invasive device that has the ability to stimulates the cerebral cortex, spinal cord, cranial nerves, and peripheral nerves electrically. The right stimulation intensity and time in using TMS will activate the motor cortex to produce motor evoked potentials (MEPs) that can be recorded from the contralateral limb muscles. The motor threshold is the lowest TMS stimulation needed to evoke the motor evoked potential (MEP) in the target muscle after the stimulation heading through the motor cortex and cortical motor tract. Because of the significant influence of body height on the conduction time needed for impulses along the corticospinal tract, the authors are interested in finding out whether there is an influence of body height on central motor conduction time throughout TMS stimulation. Method: This was an observational analytic study held on the Neurology-restoration clinic of Dr. Moewardi General Hospital using Transcranial Magnetic Stimulation (TMS) with neuro navigation from May - June 2019. Our study samples consist of 32 normal healthy people based on the general physical and neurological examination performed by the neurologist who agrees to participate in this study. The Central Motor Conduction Time obtained from TMS stimulation. The Central Motor Conduction Time was then statistically analyzed with the relationship with body height using a nonparametric Spearman’s Rho’s Analysis with confidence level of 95% and P<0.05. Results: There were n (32) respondents with mean central conduction time of 10,06ms. From the analysis and discussion, it can be seen that there was a statistical relationship between body height and central motor conduction time (CMCT) based on stimulation performed on the Abductor Pollicies Brevis (APB) muscle with a significance value of p = 0.03 (p<0.05). This study concluded that height affects central motor conduction time (CMCT) on stimulation of the Abductor Policis Brevis (APB) muscle
