Investigation of the interaction between corticomuscular coherence, motor precision and perceived difficulty in wrist flexion and extension
… between the electroencephalogram (EEG) and electromyogram (EMG) recorded during isometric force production, reflects the functional connectivity between cortex and muscle. A single muscle (flexor digitorum superficialis) study suggests a positive correlation between 15-35 Hz (beta) CMC and …

Sensory modulation of muscle synergies for motor adaptation during natural behaviors
… synergies. Previous studies have shown that electromyogram (EMG) signals collected from many muscles during natural behaviors can be reconstructed by linearly combining a few synergies, identified by the non-negative matrix factorization algorithm. But to what extent synergies are neural …

Muscle guarding during Kt-1000 testing as measured by electromyography
… muscles which cross the injured knee by an electromyogram (EMG). The muscles being tested are the Semimembranosis (SM), the Rectus femoris (RF), the Biceps femoris (BF), the lateral head of the Gastrocnemius (LG), and the medial head of the Gastrocnemius. The resting test (Zero Newtons) …

The psychophysiology of risk processing and decision making at a regional stock exchange
… (ECG), electroencephalogram (EEG), electromyogram (EMG), and temperature (Temp)-of monetarily motivated professionals making high pressure decisions. From these signals I estimate underlying physiological features, such as heart rate, changes in body temperature, and amplitude of …

Investigation of Sleep Neural Dynamics in Intracranial EEG Patients
… without accompanying electrooculogram (EOG) and electromyogram (EMG) electrodes available across labs for use in studies pertaining to neural dynamics during sleep.

Deep Multimodal Physiological Learning of Cerebral Vasoregulation Dynamics on Stroke Patients Towards Precision Brain Medicine
… (ECG), Transcranial Doppler (TCD), Electromyogram (EMG), and Blood Pressure(BP) as stroke or non-stroke subjects. The effectiveness of these algorithms is demonstrated by a classification accuracy of 90% for the combination of ECG and EMG signals. Furthermore, this research explores …

Modules in the brainstem and spinal cord underlying motor behaviors
… to investigate this question was to analyze the electromyogram (EMG) data recorded from the leg muscles during frog motor behaviors before and after neuronal transection. In my two sets of experiments, EMGs were recorded before and after transection at the level of the caudal end of the third …

A statistical framework for the analysis of neural control of movement with aging and other clinical applications
… between electroencephalogram (EEG) and electromyogram (EMG) signals into senior age. In support of classifying aging and stroke populations, the methodology selected optimal features from the time, frequency, and information theory domains. Additionally, the use of cepstral analysis was …

The role of fish physiology, behaviour, and water discharge on the attraction and passage of adult sockeye salmon (Oncorhynchus nerka) at the Seton River dam fishway, British Columbia
… and biopsied, before being implanted with electromyogram (EMG) transmitters and released near the downstream entrance of the fishway. Very few differences existed between successful and unsuccessful fish in body size, initial plasma physiology and energy state, and mean swim speed and …

Construction and assessment of a computer graphics-based model for wheelchair propulsion
… to strong relationships with the experimental electromyogram (EMG). Results from mean absolute error calculations revealed that, overall, the muscle activations determined by the model were within reasonable ranges of the experimental EMG. This was the first wheelchair propulsion study to …

Investigating neural mechanisms of hand movements in virtual reality
… (ANT Neuro). Index finger kinematics and surface Electromyogram (EMG) of the right First Dorsal Interosseous (FDI) muscle were synchronized with the EEG signals to explore the timing of MVF effects on cortical activity. In all four conditions, pronounced decrease in power of beta-band activity …

Novel ECG analysis with application to atrial fibrillation detection
… wander (BW), powerline interference (PLI), electromyogram (EMG) and motion artifact (MA). For BW and MA noise reduction, a novel Sqtwolog Threshold and High/Low pass (STHL) wavelet based filter is used. An Improved Proportionate Normalised Least Mean Square (IPNLMS) adaptive filter is used …

Mechanisms affecting post-activation potentiation following voluntary isokinetic knee extension
… Voluntary and electrically-evoked torques and electromyogram (EMG) data were captured before and after five different dynamic (isokinetic) CAs, after the participants had completed an extensive warm-up including extensive task-specific practice to the point where maximal voluntary contractile …

Effects of Tool Weight on Fatigue and Performance During Short Cycle Overhead Work Operations
… ratings based on Borg's CR-10 RPE scale, electromyogram behavior (MdPF), and hand force performance measures. Experimental findings indicated that duty cycle (percentage of total task cycle time spent working) significantly affected task duration (p<0.0001), changes in maximum voluntary …
