Exploring Human-Exoskeleton Interaction Dynamics: An In-Depth Analysis of Knee Flexion-Extension Performance across Varied Robot Assistance-Resistance Configurations.
Sensors (Basel, Switzerland)
Apr 21, 2024
Knee rehabilitation therapy after trauma or neuromotor diseases is fundamental to restore the joint functions as best as possible, exoskeleton robots being an important resource in this context, since they optimize therapy by applying tailored forces...
Machine learning reveals the control mechanics of an insect wing hinge.
Nature
Apr 17, 2024
Insects constitute the most species-rich radiation of metazoa, a success that is due to the evolution of active flight. Unlike pterosaurs, birds and bats, the wings of insects did not evolve from legs, but are novel structures that are attached to th...
Cooperative transport in sea star locomotion.
Current biology : CB
Apr 16, 2024
It is unclear how animals with radial symmetry control locomotion without a brain. Using a combination of experiments, mathematical modeling, and robotics, we tested the extent to which this control emerges in sea stars (Protoreaster nodosus) from th...
Deep Learning-Derived Myocardial Strain.
JACC. Cardiovascular imaging
Mar 27, 2024
BACKGROUND: Echocardiographic strain measurements require extensive operator experience and have significant intervendor variability. Creating an automated, open-source, vendor-agnostic method to retrospectively measure global longitudinal strain (GL...
Robot motor learning shows emergence of frequency-modulated, robust swimming with an invariant Strouhal number.
Journal of the Royal Society, Interface
Mar 27, 2024
Fish locomotion emerges from diverse interactions among deformable structures, surrounding fluids and neuromuscular activations, i.e. fluid-structure interactions (FSI) controlled by fish's motor systems. Previous studies suggested that such motor-co...
Multiple forces facilitate the aquatic acrobatics of grasshopper and bioinspired robot.
Proceedings of the National Academy of Sciences of the United States of America
Mar 25, 2024
Aquatic locomotion is challenging for land-dwelling creatures because of the high degree of fluidity with which the water yields to loads. We surprisingly found that the Chinese rice grasshopper , known for its terrestrial acrobatics, could swiftly l...
Role of compliant mechanics and motor control in hopping - from human to robot.
Scientific reports
Mar 21, 2024
Compliant leg function found during bouncy gaits in humans and animals can be considered a role model for designing and controlling bioinspired robots and assistive devices. The human musculoskeletal design and control differ from distal to proximal ...
Contributing Components of Metabolic Energy Models to Metabolic Cost Estimations in Gait.
IEEE transactions on bio-medical engineering
Mar 20, 2024
OBJECTIVE: As metabolic cost is a primary factor influencing humans' gait, we want to deepen our understanding of metabolic energy expenditure models. Therefore, this paper identifies the parameters and input variables, such as muscle or joint states...
Estimating human joint moments unifies exoskeleton control, reducing user effort.
Science robotics
Mar 20, 2024
Robotic lower-limb exoskeletons can augment human mobility, but current systems require extensive, context-specific considerations, limiting their real-world viability. Here, we present a unified exoskeleton control framework that autonomously adapts...
Machine learning models for classifying non-specific neck pain using craniocervical posture and movement.
Musculoskeletal science & practice
Mar 19, 2024
OBJECTIVE: Physical therapists and clinicians commonly confirm craniocervical posture (CCP), cervical retraction, and craniocervical flexion as screening tests because they contribute to non-specific neck pain (NSNP). We compared the predictive perfo...
