Published in 2018 at "Journal of biomechanics"

DOI: 10.1016/j.jbiomech.2017.12.001

Abstract: Low back mechanics are important to quantify to study injury, pain and disability. As in vivo forces are difficult to measure directly, modeling approaches are commonly used to estimate these forces. Validation of model estimates… read more here.

Published in 2020 at "Journal of the mechanical behavior of biomedical materials"

DOI: 10.1016/j.jmbbm.2020.104136

Abstract: Musculoskeletal models provide non-invasive and subject-specific biomechanical investigations of the musculoskeletal system. In a musculoskeletal model, muscle forces contribute to the deformation and kinematics of the joint which in turn would alter moment arms of… read more here.

Published in 2017 at "Advanced Robotics"

DOI: 10.1080/01691864.2016.1266095

Abstract: Graphical Abstract Maintenance of the upright stance is one of the basic requirements in human daily life. Stance postural control is achieved through muscle coordination based on the integration of multisensory inputs such as visual,… read more here.

Published in 2018 at "IEEE Transactions on Neural Systems and Rehabilitation Engineering"

DOI: 10.1109/tnsre.2018.2838448

Abstract: This paper aimed to develop a novel electromyography (EMG)-based neural-machine interface (NMI) that is user-generic for continuously predicting coordinated motion betweenmuscle contractionmetacarpophalangeal (MCP) and wrist flexion/extension. The NMI requires a minimum calibration procedure that only… read more here.

Published in 2021 at "IEEE Transactions on Neural Systems and Rehabilitation Engineering"

DOI: 10.1109/tnsre.2021.3081056

Abstract: High-level spinal cord injuries often result in paralysis of all four limbs, leading to decreased patient independence and quality of life. Coordinated functional electrical stimulation (FES) of paralyzed muscles can be used to restore some… read more here.

Published in 2017 at "Applied Sciences"

DOI: 10.3390/app7101067

Abstract: Weight gain and stretched abdominal muscles from an enlarged gravid uterus are remarkable features during pregnancy. These changes elicit postural instability and place strain on body segments, contributing to lower back pain. In general, the… read more here.
