Comparison of different optimal control formulations for generating dynamically consistent crutch walking simulations using a torque-driven model
Febrer Nafría, Miriam; Pallarès López, Roger; Fregly, Benjamin Jon; Font Llagunes, Josep Maria (2020-12)
Article
Accés obertWalking impairment due to spinal cord injury can be improved using active orthoses, together with some type of external support such as crutches for balance. This study explores how optimal control problem formulation ... -
Computational evaluation of psoas muscle influence on walking function following internal hemipelvectomy with reconstruction
Vega, Marleny; Li, Geng; Shourijeh, Mohammad; Ao, Di; Weinschenk, Robert; Patten, Carolynn; Font Llagunes, Josep Maria; Lewis, Valerae; Fregly, Benjamin Jon (Frontiers Media SA, 2022-09-28)
Article
Accés obertAn emerging option for internal hemipelvectomy surgery is custom prosthesis reconstruction. This option typically recapitulates the resected pelvic bony anatomy with the goal of maximizing post-surgery walking function ... -
Evaluation of Optimal Control Approaches for Predicting Active Knee-Ankle-Foot-Orthosis Motion for Individuals With Spinal Cord Injury
Febrer Nafría, Miriam; Fregly, Benjamin Jon; Font Llagunes, Josep Maria (Frontiers Media SA, 2022-01-24)
Article
Accés obertGait restoration of individuals with spinal cord injury can be partially achieved using active orthoses or exoskeletons. To improve the walking ability of each patient as much as possible, it is important to personalize ... -
Evaluation of optimal control formulations for obtaining dynamically consistent walking motions
Pallarès López, Roger; Febrer Nafría, Miriam; Fregly, Benjamin Jon; Font Llagunes, Josep Maria (2018)
Text en actes de congrés
Accés obertn recent years, interest has grown in predicting human motion, for example, to study cause-effect relations for a specific task [1]. To predict human motion, researchers typically use optimization-based methods that minimize ... -
Exoskeleton design using subject-specific synergy-driven neuromusculoskeletal models
Arones, Marleny; Font Llagunes, Josep Maria; Fregly, Benjamin Jon (2020)
Text en actes de congrés
Accés restringit per política de l'editorialMost assistive devices available today are unable to improve gait asymmetries due to the lack of knowledge on how to directly enforce kinematic symmetry in the formulation of cost functions. We designed a cost function to ... -

Influence of musculoskeletal model parameter values on prediction of accurate knee contact forces during walking
Serrancolí, Gil; Kinney, Allison; Fregly, Benjamin Jon (2020-11-18)
Article
Accés obertTreatment design for musculoskeletal disorders using in silico patient-specific dynamic simulations is becoming a clinical possibility. However, these simulations are sensitive to model parameter values that are difficult ... -
Personalised active orthoses for SCI subjects based on optimal control prediction
Febrer Nafría, Miriam; Pallarès López, Roger; Fregly, Benjamin Jon; Font Llagunes, Josep Maria (2018)
Text en actes de congrés
Accés obertThe authors are working on the personalisation of an innovative low-cost, lightweight, and easy-to-use active orthosis to facilitate over-ground walking with crutches by individuals with spinal cord injury (SCI) who possess ... -
Personalised high tibial osteotomy has mechanical safety equivalent to generic device in a case–control in silico clinical trial
