Brief Summary:
The goal of this observational study is to quantify ergonomic risk associated with traditional protective equipment in operators working in the cardiac catheterization laboratory as compared with a mobile protection system The main questions it aims to answer is
What is the mean time spent by operators in positions of high ergonomic postural risk during cases
Participants will wear IMU EMG and radiation sensors as well as complete baseline and discomfort surveys for several catheterization procedures

Detailed Description:
Study subjects will wear the following equipment on their head and back including four IMU sensors eight EMG sensors and one radiation sensor Before the catheterization procedure members of the study team will affix the IMUs on the subject and ensure that the devices are properly calibrated using a calibration procedure as per manufacturer protocol standing upright with arms and fingers pointing downward and the thumb pointing forward leaning forward hinging at the hips and a final pose returning to upright standing position Participants will periodically be asked to return to upright position to avoid IMU drift Video of the procedure will also be used for IMU data quality assurance EMG sensors will also be affixed to the subject and calibrated using the MVC function as per manufacturer protocol the subject will complete exercises to elicit the maximum muscle activation from each muscle an EMG is placed on Measures will be taken to reduce EMG impedance including cleaning the skin with alcohol wipes prior to application One radiation sensor will be clipped to the outside of the participants clothing and another will be placed near the left shoulder of the patient as the control
The IMU sensors will measure body posture angles by the fusion of data from the accelerometer magnetometer and gyroscope contained within each sensor The EMG sensors will measure the muscle activity using non-invasive electrodes on the surface of the skin The radiation dosimeter will capture radiation received by the participant during each case The acquired data will be stored locally on the device and upon completion of the procedure will be removed and the data downloaded by investigator team to the study laptop offline utilizing the Ultimum software provided by Noraxon and analyzed with Microsoft Excel and STATA statistical analytic software Neither the study sponsor RAMPART nor the supplier Noraxon will be permitted to access this data Specific datasheets will be tabulated per subject and aggregated for time spent in procedures utilizing lead vs procedures in which the RAMPART M1128 device was utilized and lead protective equipment was obviated Objective EPR will be determined and based on the amount of time the individual body segments were exposed to various postures Body angles will be assessed and stratified into risk categories defined as minimal mild moderate and high risk and will be assigned modified rapid upper limb risk assessment scores of 10 20 30 and 40 respectively and based on the measured body angles in accordance with the modified rapid upper limb assessment During each procedure the percent time spent in a prespecified range of risk categories for each body part will be calculated Study staff will mark on a datasheet the procedure type and duration for record Mean reported discomfort scores will also be calculated at the designated body regions of interest and compared between procedures as well as with and without the RAMPART device and across procedure type and duration Given that the study will be conducted with a single IMU and EMG sensor set we plan to allow for each subject to utilize the sensor system for up to six cases at a time before rotating to the subsequent subject This methodology will allow for uninterrupted and less fragmented data acquisition per study subject
Participants will be asked to complete a baseline survey consisting of questions on demographics history of orthopedic injury as well as their years of experiencein practice
The post procedure surveys will consist of body segment musculoskeletal discomfort ratings
