This paper focuses on evaluating the safety and health hazards on patients handling nurses. Manual patients handling, especially for bariatric (overweight patients) can be very risky. An experiment was conducted using digital human modeling; JACK software to measure and analyze the effect of repositioning and lifting procedures of patient handling on the lower back. Patient handling procedures was improved by showing the proper number of nurses required and the ideal anthropometries for nurses that will ensure no risk for the nurses.
