Experimentally induced stress validated by EMG activity. [PDF]

PLoS ONE, 2014
Experience of stress may lead to increased electromyography (EMG) activity in specific muscles compared to a non-stressful situation. The main aim of this study was to develop and validate a stress-EMG paradigm in which a single uncontrollable and ...

Semi-automated Detection of the Timing of Respiratory Muscle Activity: Validation and First Application

Frontiers in Physiology, 2022
Background: Respiratory muscle electromyography (EMG) can identify whether a muscle is activated, its activation amplitude, and timing. Most studies have focused on the activation amplitude, while differences in timing and duration of activity have been ...

The effect of a six-week core stability exercise training on the EMG activity, static and dynamic balance in mentally retarded teenage girls [PDF]

Sport Sciences and Health Research, 2019
Mental retardation is one of the most common mental disabilities that accounts for about 3% of the world population. The aim of the present study was to investigate the effects of a core stability exercise program on the electromyography activity, static

Brachialis Muscle Activity Can Be Measured With Surface Electromyography: A Comparative Study Using Surface and Fine-Wire Electrodes

Frontiers in Physiology, 2021
Muscle activities of the elbow flexors, especially the brachialis muscle (BR), have been measured with intramuscular electromyography (EMG) using the fine-wire electrodes. It remains unclear whether BR activity can be assessed using surface EMG.

Variation in EMG activity: a hierarchical approach [PDF]

Integrative and Comparative Biology, 2008
Recordings of naturally occurring Electromyographic (EMG) signals are variable. One of the first formal and successful attempts to quantify variation in EMG signals was Shaffer and Lauder's (1985) study examining several levels of variation but not within muscle.

Hamstring Activity Before and After Break-Point Angle Calculated By Smartphone Application During the Nordic Hamstring Exercise

International Journal of Sports Physical Therapy, 2023
# INTRODUCTION Previous studies have reported a gradual decrease in biceps femoris (BF) electromyography (EMG) activity after the break-point angle (BPA) during the Nordic hamstring exercise (NHE).

Higher Leg and Trunk Muscle Activation during Balance Control in Copers versus People with Chronic Ankle Instability and Healthy Female Athletes

Sports, 2022
More than 70% of people with ankle sprain experience chronic ankle instability. However, some people are well adapted to this damage (copers) and do not suffer from chronic ankle instability (CAI).

Neuromuscular activity of the lower‐extremities during running, landing and changing‐of‐direction movements in individuals with anterior cruciate ligament reconstruction: a review of electromyographic studies

Journal of Experimental Orthopaedics, 2023
Purpose Running, jumping/landing and cutting/change of direction (CoD) are critical components of return to sport (RTS) following anterior cruciate ligament reconstruction (ACLR), however the electromyographic (EMG) activity patterns of the operated leg ...

Processing of EMG Signals with High Impact of Power Line and Cardiac Interferences

Applied Sciences, 2021
This work deals with electromyography (EMG) signal processing for the diagnosis and therapy of different muscles. Because the correct muscle activity measurement of strongly noised EMG signals is the major hurdle in medical applications, a raw measured ...
