RULA/REBA
This study aims to propose the OpenPose-based system for computing joint angles and RULA/REBA scores and validate against the reference motion capture system, and compare its performance to the Kinect-based system
Ergonomic postural assessment using a new open-source human pose
estimation technology (OpenPose)
frontal/non-frontal views were analyzed. OpenPose showed good performance under all task conditions, whereas Kinect performed significantly worse than OpenPose especially at cases with body occlusions or non-frontal tracking. The findings suggested that OpenPose could be a promising technology to measure joint angles

The aims of this study were: to identify surface electromyography (sEMG)-based indices of trunk muscles acquired during the execution of lifting tasks designed using the revised NIOSH lifting equation and featuring

progressively increasing lifting index (LI); to study changes of these indices in relation to the LI; to evaluate the
relationship between the identified indices and forces ( ) FL S 5 1 − and moments ( ) ML S 5 1 − at the L5-S1 joint. sEMG,
kinematic and kinetic data of 20 male workers were recorded in three conditions
Findings suggest a promising use of wearable sEMG sensors in developing instrumental-based risk assessment
tools in either the laboratory or workplace. In fact, some indices discriminate the investigated risk levels and
correlate with the variables that generate the damage.

Researchers have sought to identify ergonomic risks of continuous motions in 3D visualizations to achieve proactive workplace designs
This paper proposes an automated 3D standard
motion time-based ergonomic risk analysis method that systematically determines motion times and accurately
quantifies ergonomic risks of continuous motions for workplace design. The ergonomic risk of continuous motion

is assessed using existing tools such as REBA and RULA by incorporating standard motion times determined by a
predetermined motion time system. The effectiveness of the proposed method is validated in a case study

Improving the risk assessment capability of the revised NIOSH lifting
equation by incorporating personal characteristics
This study explores the utility of adding personal characteristics such as the estimated L5/S1 Intervertebral Disc (IVD) cross-sectional area, age, gender and Body Mass Index to the Revised NIOSH Lifting Equation (RNLE) with the goal to improve risk assessment
RNLE risk assessment was improved by incorporation of personal characteristics. Adding gender and intervertebral disc size multipliers to the RNLE raised the odds ratio for a CLI of 3.0 from 6.71 (CI: 2.2–20.9) to 24.75 (CI: 2.8–215.4). Similarly, performance was either unchanged or improved when some existing multipliers were removed. The most promising RNLE change involved incorporation of a multiplier based on the estimated IVD cross-sectional area (CSA
