OPTIMAL EMG PLACEMENT FOR A ROBOTIC PROSTHESIS CONTROLLER WITH SEQUENTIAL, ADAPTIVE FUNCTIONAL ESTIMATION (SAFE)

ANNALS OF APPLIED STATISTICS, 14(3), 1164–1181.

By: J. Stallrich n, M. Islam, A. Staicu n , D. Crouch n, L. Pan* & H. Huang n 

Contributors: J. Stallrich n, N. Islam, A. Staicu n , D. Crouch n, L. Pan* & H. Huang n 

author keywords: Electromyography signal; varying functional regression; functional variable selection; adaptive group LASSO; correlated functional predictors; sequential adaptive functional estimation
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)

2019 journal article

Comparing EMG-Based Human-Machine Interfaces for Estimating Continuous, Coordinated Movements

IEEE TRANSACTIONS ON NEURAL SYSTEMS AND REHABILITATION ENGINEERING, 27(10), 2145–2154.

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
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.

2017 journal article

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

JOURNAL OF NEURAL ENGINEERING, 14(3).

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
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.

2016 journal article

Lumped-parameter electromyogram-driven musculoskeletal hand model: A potential platform for real-time prosthesis control

JOURNAL OF BIOMECHANICS, 49(16), 3901–3907.

By: D. Crouch n & H. Huang n 

Contributors: D. Crouch n & H. Huang n 

author keywords: Wrist; Simulation; Amputation; Parameter; Optimization
MeSH headings : Adult; Artificial Limbs; Biomechanical Phenomena; Brain-Computer Interfaces; Electromyography / methods; Female; Forearm / physiology; Hand / physiology; Humans; Male; Metacarpophalangeal Joint / physiology; Models, Anatomic; Movement / physiology; Range of Motion, Articular / physiology; Robotics; Wrist Joint / physiology; Young Adult
TL;DR: The results showed the promise of a lumped-parameter, EMG-driven musculoskeletal model for hand/wrist kinematic estimation, and might be useful for EMG control of powered upper limb prostheses, but more work is needed to demonstrate its online performance. (via Semantic Scholar)

A cyber expert system for auto-tuning powered prosthesis impedance control parameters

Annals of Biomedical Engineering, 44(5), 1613–1624.

By: H. Huang n , D. Crouch n, M. Liu n, G. Sawicki n & D. Wang  n

Contributors: H. Huang n , D. Crouch n, M. Liu n, G. Sawicki n & D. Wang  n

MeSH headings : Ankle Joint; Electric Impedance; Female; Gait; Humans; Knee Joint; Knee Prosthesis; Male; Walking
TL;DR: A novel cyber expert system that encoded HME tuning decisions as computer rules to auto-tune control parameters for a powered knee (passive ankle) prosthesis and observed normative prosthetic knee kinematics and improved or slightly improved gait symmetry and step width within each subject.

TL;DR: Subjects had less reserve strength available for performing upper extremity tasks and, therefore, may be less adaptive to strength declines due to injury progression and normal aging. (via Semantic Scholar)
