EMG-based lumbosacral joint compression force prediction using a support vector machine.
Medical engineering & physics
Sep 17, 2019
Electromyography-assisted optimization (EMGAO) approach is widely used to predict lumbar joint loads under various dynamic and static conditions. However, such approach uses numerous anthropometric, kinematic, kinetic, and electromyographic data in t...
Coupled artificial neural networks to estimate 3D whole-body posture, lumbosacral moments, and spinal loads during load-handling activities.
Journal of biomechanics
Sep 12, 2019
Biomechanical modeling approaches require body posture to evaluate the risk of spine injury during manual material handling. The procedure to measure body posture via motion-analysis techniques as well as the subsequent calculations of lumbosacral mo...
Femoral Contact Forces in the Anterior Cruciate Ligament Deficient Knee: A Robotic Study.
Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association
Nov 2, 2018
PURPOSE: To measure contact forces (CFs) at standardized locations representative of clinical articular cartilage defects on the medial and lateral femoral condyles during robotic tests with simulated weightbearing knee flexion.
Design and Computational Modeling of a Modular, Compliant Robotic Assembly for Human Lumbar Unit and Spinal Cord Assistance.
Scientific reports
Oct 31, 2017
Wearable soft robotic systems are enabling safer human-robot interaction and are proving to be instrumental for biomedical rehabilitation. In this manuscript, we propose a novel, modular, wearable robotic device for human (lumbar) spine assistance th...

Machine learning techniques for the optimization of joint replacements: Application to a short-stem hip implant.
PloS one
Sep 5, 2017
Today, different implant designs exist in the market; however, there is not a clear understanding of which are the best implant design parameters to achieve mechanical optimal conditions. Therefore, the aim of this project was to investigate if the g...
Artificial neural networks to predict 3D spinal posture in reaching and lifting activities; Applications in biomechanical models.
Journal of biomechanics
Jul 15, 2016
Spinal posture is a crucial input in biomechanical models and an essential factor in ergonomics investigations to evaluate risk of low back injury. In vivo measurement of spinal posture through the common motion capture techniques is limited to equip...
Sex-based differences in knee ligament biomechanics during robotically simulated athletic tasks.
Journal of biomechanics
Mar 8, 2016
ACL injury rates are greater in female athletes than their male counterparts. As female athletes are at increased risk, it is important to understand the underlying mechanics that contribute to this sex bias. The purpose of this investigation was to ...
Predicting ground contact events for a continuum of gait types: An application of targeted machine learning using principal component analysis.
Gait & posture
Mar 4, 2016
An ongoing challenge in the application of gait analysis to clinical settings is the standardized detection of temporal events, with unobtrusive and cost-effective equipment, for a wide range of gait types. The purpose of the current study was to inv...
Robot-aided in vitro measurement of patellar stability with consideration to the influence of muscle loading.
Biomedical engineering online
Jul 23, 2015
BACKGROUND: Anterior knee pain is often associated with patellar maltracking and instability. However, objective measurement of patellar stability under clinical and experimental conditions is difficult, and muscular activity influences the results. ...
Quantification of loading in biomechanical testing: the influence of dissection sequence.
Journal of biomechanics
Jun 26, 2015
Sequential dissection is a technique used to investigate loads experienced by articular tissues. When the joint of interest is tested in an unconstrained manner, its kinematics change with each tissue removal. To address this limitation, sufficiently...
