author keywords: Electromyography signal; varying functional regression; functional variable selection; adaptive group LASSO; correlated functional predictors; sequential adaptive functional estimation
topics (OpenAlex): Muscle activation and electromyography studies; EEG and Brain-Computer Interfaces; Neuroscience and Neural Engineering
TL;DR: A novel decoder based on a dynamic, functional linear model with velocity or acceleration as its response and the recent past EMG signals as functional covariates is proposed, increasing the predictive capability of a single EMG signal compared to existing decoders. (via Semantic Scholar)

By: L. Pan n, D. Crouch n & H. Huang n 

Contributors: L. Pan n, D. Crouch n & H. Huang n 

author keywords: Electromyography (EMG); musculoskeletal model; linear regression; artificial neural network; comparison
MeSH headings : Adult; Algorithms; Amputees; Biomechanical Phenomena; Electromyography / methods; Healthy Volunteers; Humans; Male; Models, Theoretical; Movement / physiology; Musculoskeletal Physiological Phenomena; Nerve Net; Psychomotor Performance; Radius; User-Computer Interface; Wrist / anatomy & histology; Wrist / physiology; Wrist Joint / anatomy & histology; Wrist Joint / physiology; Young Adult
topics (OpenAlex): Muscle activation and electromyography studies; Motor Control and Adaptation; EEG and Brain-Computer Interfaces
TL;DR: Comparing a musculoskeletal model (MM) with two data-driven approaches, linear regression (LR) and artificial neural network (ANN), for predicting continuous wrist and hand motions for EMG-based interfaces suggests that incorporating musculOSkeletal knowledge into EMg-based human-machine interfaces could improve the estimation of continuous, coordinated motion.

Musculoskeletal model-based control interface mimics physiologic hand dynamics during path tracing task

Crouch, D. L., & Huang, H. (2017, February 21). Journal of Neural Engineering, Vol. 14.

By: D. Crouch n & H. Huang n 

Contributors: D. Crouch n & H. Huang n 

author keywords: electromyogram; prosthesis control; musculoskeletal model; dynamic simulation; amputation
MeSH headings : Adult; Amputees; Biomimetics / methods; Computer Simulation; Feasibility Studies; Female; Hand / physiology; Humans; Joints / innervation; Joints / physiology; Male; Middle Aged; Models, Neurological; Movement / physiology; Muscle, Skeletal / innervation; Muscle, Skeletal / physiology; Psychomotor Performance / physiology; Reproducibility of Results; Sensitivity and Specificity
topics (OpenAlex): Muscle activation and electromyography studies; EEG and Brain-Computer Interfaces; Motor Control and Adaptation
TL;DR: The result suggests that the amputee’s motor control patterns were not accustomed to the multi-joint dynamics of the wrist and hand, possibly as a result of post-amputation cortical plasticity, disuse, or sensory deficits, and is potentially a practical and effective control platform for multifunctional myoelectric prostheses that could restore more life-like hand function for individuals with upper limb amputation.
