Identification of neural and non-neural origins of joint hyper-resistance based on a novel neuromechanical model.

This paper develops a neuromechanical model to distinguish neural and non-neural causes of joint hyper-resistance in children with cerebral palsy using pendulum test data.

A dynamic foot model for predictive simulations of gait reveals causal relations between foot structure and whole body mechanics

This paper develops a dynamic foot model to simulate gait and identifies key foot properties that influence walking mechanics and energy efficiency.

Assisting walking balance using a bio-inspired exoskeleton controller

This paper presents a bio-inspired exoskeleton controller that improves walking balance and reduces muscle activity by mimicking human neural control mechanisms.

Modeling toes contributes to realistic stance knee mechanics in three-dimensional predictive simulations of walking

This study shows that modeling toes and metatarsophalangeal joints improves stance knee mechanics in predictive walking simulations, but not ankle plantarflexion.

Validation of a smartphone embedded inertial measurement unit for measuring postural stability in older adults

This study compares postural stability measurements from a smartphone IMU and a force plate in older adults, finding moderate correlation but lower reliability for the smartphone.

Achilles tendon stiffness minimizes the energy cost in simulations of walking in older but not in young adults

This study simulates walking in young and older adults to show that Achilles tendon stiffness and walking patterns both independently affect energy cost, but stiffness has a smaller impact.

Habitual foot strike pattern does not affect simulated Triceps Surae muscle metabolic energy consumption during running

Ultrasound-based optimal parameter estimation improves assessment of calf muscle-tendon interaction during walking

This study introduces an optimal estimation algorithm to estimate calf muscle-tendon parameters during walking, showing improved accuracy and reduced metabolic energy cost compared to generic parameters.

Physics-based predictive simulations to explore the differential effects of motor control and musculoskeletal deficits on gait dysfunction in cerebral palsy: a retrospective case study

This study uses physics-based simulations to identify that altered muscle-tendon properties, rather than neuromuscular control or spasticity, are the main cause of crouch gait in a child with cerebral palsy.

Algorithmic differentiation improves the computational efficiency of OpenSim-based optimal control simulations of movement

This study shows that algorithmic differentiation (AD) significantly improves computational efficiency in OpenSim-based optimal control simulations compared to finite differences (FD) and other AD tools.
