Ergonomic risks, driven by strenuous physical demands in complex work settings, are
prevalent across industries. Addressing these challenges through detailed assessment and …

Physical fatigue is not only an indication of the user's physical condition and/or need for
sleep or rest, but can also be a significant symptom of various diseases. This fatigue affects …

Wearable inertial measurement units (IMUs) are used increasingly to estimate
biomechanical exposures in lifting-lowering tasks. The objective of the study was to develop …

Repetitive occupational lifting has been shown to create an increased risk for incidence of
back pain. Ergonomic workstations that promote proper lifting technique can reduce risk, but …

Although several studies have used wearable sensors to analyze human lifting, this has
generally only been done in a limited manner. In this proof-of-concept study, we investigate …

Overexertion in lifting tasks is one of the leading causes of occupational injuries. The load
weight is the key information required to evaluate the risk of a lifting task. However, weight …

Safety practitioners widely use the lifting index (LI) to determine workers' lifting risk but are
hampered by the difficulties of estimating the lifting load without intervention or intrusive …

Objective A computer vision method was developed for estimating the trunk flexion angle,
angular speed, and angular acceleration by extracting simple features from the moving …

We used an armband with embedded surface electromyography (sEMG) electrodes,
together with machine-learning (ML) models, to automatically detect lifting-lowering activities …

Occupationally-induced back pain is a leading cause of reduced productivity in industry.
Detecting when a worker is lifting incorrectly and at increased risk of back injury presents …
