Human Electro-Muscular Incapacitation (HEMI) Mechanisms Study 4: An Examination of the Deleterious Physiological Effects of Variations in the Duty Cycle Parameters

Abstract

This study is the fourth in a series of studies, the collective objective of which is to elucidate further the mechanisms of action of HEMI devices, their relationship to alternate duty cycles, and the deleterious effects caused by various duty cycles. Understanding how the mechanisms of action and work lead to the deleterious effects is critical to better quantifying and qualifying the actual safety risks, identifying vulnerable populations, as well as attempting to improve the efficacy and safety of this family of devices. From previous studies, it was clear that HEMI stimuli produced responses that overwhelm physiological compensatory mechanisms and produced biochemical abnormalities well above the measurement capabilities of laboratory equipment. We therefore endeavored to measure work as a method to differentiate the deleterious effects of a wide range of duty cycles. We used accelerometers that measured movements in three (3) directions (i.e., the X, Y and Z directions). The movements were used to calculate power and reported as work.
