Quantifying the Participatory Ergonomic Effects of Training and a Work Analysis Tool on Operator Performance and Well-Being
… in which participants analyzed and redesigned a manual material handling job. The effects of this PE approach were quantified by measuring a reduction of risk factors associated with the job and by measuring a lift index of the lifting task that indicates a risk for injury. Many authors state or …

Evaluation of Markerless Motion Capture to Assess Physical Exposures During Material Handling Tasks
Manual material handling (MMH) tasks are associated with the development of work-related musculoskeletal disorders (WMSDs). Minimizing the frequency and intensity of handling objects is an ideal solution, yet MMH remains an integral part of many industry sectors, including manufacturing, …

Effects of Localized Muscle Fatigue on Postural Control: Interactive Effects with Inclined Surfaces and Unexpected Loads, and Intervention Efficacy
… to muscle fatigue, inclined surfaces, and manual material handling tasks.

Development and Evaluation of Methods to Assess Physical Exposures in the Workplace
… of an IMC system was evaluated during several manual material handling (MMH) tasks, in terms of estimated body kinematics and kinetics at selected body parts. A practical issue, regarding calibrating the IPM system in the field, was addressed by defining an ad hoc global coordinate system using …

Biomechanical Analysis and Modeling of Back-Support Exoskeletons for Use in Repetitive Lifting Tasks
… with "physical" risk factors prevalent in manual material handling (MMH) tasks. Back-support exoskeletons (BSEs) are a promising ergonomic intervention to mitigate LBP risk, by reducing muscular exertion and spine loading. The purpose of this work was to help better understand both the …

Traditional Posterior Load Carriage: Ergonomic Assessment and Intervention Efficacy
… of musculoskeletal symptoms (MSS) among manual material handling (MMH) workers. However, limited investigations have been undertaken among one large group of workers using a particular MMH method called traditional posterior load carriage (PLC). Such load carriage is typically done …

Trunk Biomechanical Responses during Sudden Loading
… is a significant risk among workers who perform manual material handling tasks (MMH). Therefore, it is critical to understand the effects of influential factors on back injury risks during sudden loading, and to develop load handling strategies that can reduce the biomechanical impacts to the …

Identification and Modification of Risk Factors Contributing to Slip- and Trip-Induced Falls
… risk. Healthy young adults performed a simulated manual material handling (MMH) task, using either heavy or light boxes, for two hours. Gait measures related to risk of tripping and slipping were assessed before and after the task. Reactive balance during one laboratory-induced trip was also …

Assessing the Effects of Exoskeleton Use on Balance and Postural Stability
… risk of overexertion injuries associated with manual material handling. However, it is important to understand whether BSEs also introduce any unintended safety challenges. One potential risk associated with BSE use is increased risk of falls, since their extra weight, rigid structure, and …

Cyber-physical systems to monitor the efficiency and sustainability of human-centric manufacturing systems
… configurations and the related efficiency in manual material handling activities. This twofold level of analysis enables to eventually increase in-plant productivity while optimizing workers’ efforts in replenishment routes. The logistic investigation offers similar takes by monitoring the …

Development and Assessment of Smart Textile Systems for Human Activity Classification
Wearable sensors and systems have become increasingly popular for diverse applications. An emerging technology for physical activity assessment is Smart Textile Systems (STSs), comprised of sensitive/actuating fiber, yarn, or fabric that can sense an external stimulus. All required components of an …
