Evaluation of antigravitational support levels provided by a passive upper-limb occupational exoskeleton in repetitive arm movements
Upper-limb occupational exoskeletons to support the workers' upper arms are typically designed to provide antigravitational support. Although typical work activities require workers to perform static and dynamic actions, the majority of the studies in lite ...
London2024Understanding motor control and impairment: An upper-limb model for muscular assessment
The human upper limb is a complex musculoskeletal system that can still perform various tasks with impressive efficacy thanks to the ability of the central nervous system to control and modulate the activation of more than 40 muscles.Stroke is a leading ca ...
EPFL2023Modelisation of fiber reinforced DEAs
The aim of this "Face Reconstruction" project is to enable people with paralysis in one half of their face to recover facial expressions. To do this, we’ll replace the paralyzed muscle with an DEA which we’ll connect to the nerve on the other side of the f ...
2023Estimating muscle activation from EMG using deep learning-based dynamical systems models
Objective. To study the neural control of movement, it is often necessary to estimate how muscles are activated across a variety of behavioral conditions. One approach is to try extracting the underlying neural command signal to muscles by applying latent ...
2022Personal Mobility with Synchronous Trunk-Knee Passive Exoskeleton: Optimizing Human-Robot Energy Transfer
Diego Felipe Paez Granados, Yang Chen
We present a personal mobility device for lower- body impaired users through a light-weighted exoskeleton on wheels. On its core, a novel passive exoskeleton provides postural transition leveraging natural body postures with support to the trunk on sit-to- ...
2022Slim: Explicit Slot-Intent Mapping With Bert For Joint Multi-Intent Detection And Slot Filling
Boi Faltings, Fei Mi, Fengyu Cai, Wanhao Zhou
Utterance-level intent detection and token-level slot filling are two key tasks for spoken language understanding (SLU) in task-oriented systems. Most existing approaches assume that only a single intent exists in an utterance. However, there are often mul ...
IEEE2022Mechanotaxis directs Pseudomonas aeruginosa twitching motility
Alexandre Louis André Persat, Lorenzo Anton-Louis Talà, Xavier Jean-Yves Pierrat, Jose Negrete Jr, Joanne Netter Engel, Marco Julian Kühn
The opportunistic pathogen Pseudomonas aeruginosa explores surfaces using twitching motility powered by retractile extracellu-lar filaments called type IV pili (T4P). Single cells twitch by sequen-tial T4P extension, attachment, and retraction. How single ...
NATL ACAD SCIENCES2021The gut microbiota influences skeletal muscle mass and function in mice
Johan Auwerx, Hongbo Zhang, Walter Wahli
The functional interactions between the gut microbiota and the host are important for host physiology, homeostasis, and sustained health. We compared the skeletal muscle of germ-free mice that lacked a gut microbiota to the skeletal muscle of pathogen-free ...
AMER ASSOC ADVANCEMENT SCIENCE2019Muscle activities in similar arms performing identical tasks reveal the neural basis of muscle synergies
Are the muscle synergies extracted from multiple electromyographic signals an expression of neural information processing, or rather a by-product of mechanical and task constraints? To address this question, we asked 41 right-handed adults to perform a var ...
SPRINGER2019Myoelectric activity imaging and decoding with multichannel surface EMG for enhanced everyday life applicability
Silvestro Micera, Fiorenzo Artoni, Stefan Erich Hans-Jürgen Kreipe
Surface electromyography (sEMG) allows to evaluate neurophysiological aspects of movements. The traditional muscle-specific sEMG approach requires considerable expertise to correctly position bipolar derivations over each muscle of interest. This reduces t ...
