Muscles for hand functions and movements play a major role in basic daily activities such aswriting lifting objects. The main digit of the finger differentiating gesture is thumb its muscles are intrinsic muscles. However, transradial amputees, despite loss access to muscles, any information from extrinsic would be paramount non-negotiablein creating perfect prosthesis. As such, research dedica...

PURPOSE Developing a real time method for the localization of muscle activity regions from high density surface electromyogram (EMG). METHOD The inverse problem of source localization is solved by a regularized technique applied to an over-determined problem searching for the least mean squares approximation of the recorded signal with a linear combination of a set of basis waveforms (subject...

Muscle fatigue in the anterior temporal and masseter muscles of 13 normal subjects was induced by maximum clench in intercuspal position. Frequency analysis using a fast Fourier transform algorithm to obtain the power-spectral density function and the power spectrum of the electromyogram signal indicated that the power spectra obtained during fatigue were statistically significantly shifted to ...

Introduction Endurance of the back muscles is considered as an important contributing factor in the development of low back pain. Currently, researchers are looking at reliable methods for measuring the back muscle’s fatigue rate by surface electromyogram (EMG). Many of these studies are still at the experimental stage and the feasibility of using EMG as a clinical tool for such purpose remains...

The probability density function (PDF) of the surface electromyogram (EMG) signals has been modelled with Gaussian and Laplacian distribution functions. However, a general consensus upon the PDF of the EMG signals is yet to be reached, because not only are there several biological factors that can influence this distribution function, but also different analysis techniques can lead to contradic...

We provide a novel method to infer finger flexing motions using a four-channel surface electromyogram (EMG). Surface EMG signals can be recorded from the human body non-invasively and easily. Surface EMG signals in this study were obtained from four channel electrodes placed around the forearm. The motions consist of the flexion of five single fingers (thumb, index finger, middle finger, ring f...

Although various types of myoelectric prosthetic hands using surface electromyogram have been developed, the placement electrodes to acquire potential needs be adjusted by a specialist, and differs from individual individuals, so it user. Also, is not covered health insurance in Japan, there are technical fees for product price initial setup. We propose method electrode pretreatment that does r...
