Automated Workers Ergonomic Risk Assessment in Manual Material Handling using sEMG Wearable Sensors and Machine Learning [PDF]
Electronics. 2021; 10(20):2558, 2021 Manual material handling tasks have the potential to be highly unsafe from an ergonomic viewpoint. Safety inspections to monitor body postures can help mitigate ergonomic risks of material handling. However, the real effect of awkward muscle movements, strains, and excessive forces that may result in an injury may not be identified by external cues ...

The energy of muscle contraction. II. Transverse compression and work [PDF]
, 2020 In this study we reproduced this compression-induced reduction in muscle force through the use of a three-dimensional finite element model of contracting muscle. The model used the principle of minimum total energy and allowed for the redistribution of energy through different strain energy-densities; this allowed us to determine the importance of the ...

A Sonomyography-based Muscle Computer Interface for Individuals with Spinal Cord Injury [PDF]
arXiv, 2023 Impairment of hand functions in individuals with spinal cord injury (SCI) severely disrupts activities of daily living. Recent advances have enabled rehabilitation assisted by robotic devices to augment the residual function of the muscles. Traditionally, non-invasive electromyography-based peripheral neural interfaces have been utilized to sense ...

Activation of a muscle as a mapping of stress-strain curves [PDF]
Extreme Mechanics Letters 28 (2019): 37-42, 2019 The mathematical modeling of the contraction of a muscle is a crucial problem in biomechanics. Several different models of muscle activation exist in literature. A possible approach to contractility is the so-called active strain: it is based on a multiplicative decomposition of the deformation gradient into an active contribution, accounting for the ...

Investigating the Correlation between Force Output, Strains, and Pressure for Active Skeletal Muscle Contractions [PDF]
arXiv, 2023 Experimental observations suggest that the force output of the skeletal muscle tissue can be correlated to the intra-muscular pressure generated by the muscle belly. However, pressure often proves difficult to measure through in-vivo tests. Simulations on the other hand, offer a tool to model muscle contractions and analyze the relationship between ...

The energy of muscle contraction. I. Tissue force and deformation during isometric contractions [PDF]
, 2020 During contraction the energy of muscle tissue increases due to energy from the hydrolysis of ATP. This energy is distributed across the tissue as strain-energy potentials in the contractile elements, strain-energy potential from the 3D deformation of the base-material tissue (containing cellular and ECM effects), energy related to changes in the ...

Personalized modeling for real-time pressure ulcer prevention in sitting posture [PDF]
Journal of Tissue Viability, Elsevier, 2018, 27 (1), pp.54 - 58, 2018 , Ischial pressure ulcer is an important risk for every paraplegic person and a major public health issue. Pressure ulcers appear following excessive compression of buttock's soft tissues by bony structures, and particularly in ischial and sacral bones.

Uncertainty quantification of a three-dimensional in-stent restenosis model with surrogate modelling [PDF]
arXiv, 2021 In-Stent Restenosis is a recurrence of coronary artery narrowing due to vascular injury caused by balloon dilation and stent placement. It may lead to the relapse of angina symptoms or to an acute coronary syndrome. An uncertainty quantification of a model for In-Stent Restenosis with four uncertain parameters (endothelium regeneration time, the ...

Predictive modelling of training loads and injury in Australian football [PDF]
, 2017 To investigate whether training load monitoring data could be used to predict injuries in elite Australian football players, data were collected from elite athletes over 3 seasons at an Australian football club. Loads were quantified using GPS devices, accelerometers and player perceived exertion ratings.

Development Of A Low Cost System For Lifting Related Injury Analysis [PDF]
arXiv, 2021 In the developing countries, most of the Manual Material Handling (MMH) related tasks are labor-intensive. It is not possible for these countries to assess injuries during lifting heavy weight, as multi-camera motion capture, force plate and electromyography (EMG) systems are very expensive.
