The purpose of this project is to quantitatively assess the physiological responses expressed by a patient while receiving a simulated mammogram using Hologic’s 3Dimensions Mammography System. This project is a continuation of last year’s efforts to determine if differences in paddle designs have a significant effect on the comfort experienced by the subject. This is an IRB-approved study collecting data from 25 participants to analyze the stress differences between the standard of care (a flat paddle) and the SmartCurve™ paddle supplied by Hologic Inc. Our group focused on the electromyography (EMG) and balance control data measured during the study as indicators of physiological stress.
