Characteristics of muscle synergy and anticipatory synergy adjustments strategy when cutting in different angles.

Gait & Posture, 2023
BACKGROUND Cutting is a quick change of direction that challenges body balance and stability. As the cut-angle increases, the elite athlete can achieve higher performance by pre-adjusting the posture of the lower limb joints.

Quantitative Assessment via Multi-Domain Fusion of Muscle Synergy Associated With Upper-Limb Motor Function for Stroke Rehabilitation

IEEE Transactions on Biomedical Engineering, 2023
Quantitative assessment of upper limb motor function aids therapists in providing appropriate rehabilitation strategies, which plays an essential role in post-stroke rehabilitation. Traditional assessments, relying on clinical scales or kinematic metrics,

A Muscle Synergy-Driven ANFIS Approach to Predict Continuous Knee Joint Movement

IEEE transactions on fuzzy systems, 2022
Continuous motion prediction plays a significant role in realizing seamless control of robotic exoskeletons and orthoses. Explicitly modeling the relationship between coordinated muscle activations from surface electromyography (sEMG) and human limb ...

Synchronous Muscle Synergy Evaluation of Jaw Muscle Activities during Chewing at Different Speeds, a Preliminary Study

Brain Sciences, 2023
Human mastication is a complex and rhythmic biomechanical process regulated by the central nervous system (CNS). Muscle synergies are a group of motor primitives that the CNS may combine to simplify motor control in human movement.

Upper Limb Motor Function Quantification in Post-Stroke Rehabilitation Using Muscle Synergy Space Model

IEEE Transactions on Biomedical Engineering, 2022
The muscle synergy hypothesis assumes that the nervous system controls muscles in groups to simplify behavioral tasks, which makes it possible for modularizing motor function assessment. This paper presents a new assessment method based on muscle synergy

Evaluation of Muscle Synergy During Exoskeleton-Assisted Walking in Persons With Multiple Sclerosis

IEEE Transactions on Biomedical Engineering, 2022
Objective: Gait deficit after multiple sclerosis (MS) can be characterized by altered muscle activation patterns. There is preliminary evidence of improved walking with a lower limb exoskeleton in persons with MS.

Running-induced fatigue influences lower extremity muscle synergy and related biomechanics.

Gait & Posture
BACKGROUND Fatigue changes muscle activation patterns as an adaptation strategy in multi-joint movements. However, due to groups of muscles involved in running, the across-muscle neurological regulation before and after fatigue is unclear.

Correlation Evaluation of Functional Corticomuscular Coupling With Abnormal Muscle Synergy After Stroke

IEEE Transactions on Biomedical Engineering, 2021
Objective: While neuroplasticity and functional reorganization during motor recovery can be indirectly reflected and evaluated by functional corticomuscular coupling (fCMC), little work has been published regarding the cortical origin of abnormal muscle ...
