Background: Surface Electromyography (SEMG) signal has used in monitoring muscle activities. It has been widely applied in many areas, such as body member prosthesis, noise cancellation for braincomputer interface, and robotics. The SEMG acquisition method for collecting the signal with low-noise has extensively investigated in the last decade. The objective of this study is to review the recen...

19 Cortex–muscle coherence (CMC) reflects coupling between magnetoencephalography (MEG) 20 and surface electromyography (sEMG), being strongest during isometric contraction, but absent, 21 for unknown reasons, in some individuals. 22 We used a novel non-magnetic high-density sEMG (HD-sEMG) electrode grid (36 mm x 12 23 mm; 60 electrodes separated by 3 mm) to study effects of sEMG recording site...

Lumbar spine accessory movements, used by therapists in the treatment of patients with low back pain, is thought to decrease paravertebral muscular activity; however there is little research to support this suggestion. This study investigated the effects of lumbar spine accessory movements on surface electromyography (sEMG) activity of erector spinae. A condition randomised, placebo controlled,...

The purpose of this study was to determine whether electromyography (EMG) muscle activities around the knee differ during sit-to-stand (STS) and returning task for females wearing shoes with different heel heights. Sixteen healthy young women (age = 25.2 ± 3.9 years, body mass index = 20.8 ± 2.7 kg/m2) participated in this study. Electromyography signals were recorded from the two muscles, vast...

An electrophysiological phenomenon running up and down the spine, elicited by light pressure contact at very precise points and thereafter taking the external appearance of an undulatory motion of the spine, is analyzed from its standing wave, coherence, and synchronization-at-a-distance properties. This standing spinal wave can be elicited in both normal and quadriplegic subjects, which demons...

Head orientation prediction is one of the solutions to reduce end-to-end latency on Virtual Reality (VR) systems and important since it can alleviate negative effects like motion sickness. This study compared head models from two different electromyography (EMG) systems: surface EMG (sEMG) High-Density (HD-EMG). The deep learning method was used train model, results showed that model with input...

In this paper, a novel closed-loop model based on surface electromyography (sEMG) comprised long short term memory (LSTM) network and discrete-time zeroing neural algorithm called (ZNN), which is developed to estimate joint angles angular velocities of human upper limb with damping. The dynamic damping set up as the initial equation. Then, LSTM proposed an open-loop described input-output relat...

Electromyography is the technique of recording electrical potentials associated with muscular activity. Needle electrodes may be inserted in the muscle being monitored, or surface electrodes may be placed on the skin overlying the muscles being studied. Both techniques have been used for the examination of paraspinal and peripheral muscle function. However, surface EMG and needle EMG are not in...

Musculoskeletal neck discomfort is prevalent in many occupations and has been the focus of much research employing surface electromyography (sEMG). Significant differences in experimental methods among researchers make comparisons across studies difficult. The goal of the current research was to use empirical methods to answer specific methodological questions concerning use of sEMG in evaluati...
