Measurement and Analysis of Surface EMG during Dynamic Movement.

Important Factors in surface EMG measurement

Denoising and Analysis of Surface EMG Signals

In this research, surface electromyography (SEMG) signal analysis from the right rectus femoris muscle is performed during walk. Wavelet transform (WT) has been applied for removing noise from the surface SEMG. Gaussianity tests are conducted to understand changes in muscle contraction and to quantify the effectiveness of the noise removal process. Results show that the proposed method can effe...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...

Emg-informed Computed Muscle Control for Dynamic Simulations of Movement

INTRODUCTION Computed Muscle Control (CMC) is an efficient method for estimating muscle activations and forces from kinematic and ground reaction force data [1]. However, it can fail to replicate some muscle activation characteristics found in electromographic (EMG) recordings. For instance, muscles often activate in anticipation of events such as heel strike, and these anticiptory responses ar...

Effects of muscle kinematics on surface EMG amplitude and frequency during fatiguing dynamic contractions.

Fifteen male subjects performed a repetitive elbow flexion/extension task with a 7-kg mass until exhaustion. Average joint angle, angular velocity, and biceps brachii surface electromyographic (EMG) amplitude (aEMG) and mean power frequency (MPF) were calculated with each consecutive 250-ms segment of data during the entire trial. Data were separated into concentric or eccentric phases and into...
