The estimation of the grip force and the 3D push-pull force (push and pull force in the three dimension space) from the electromyogram (EMG) signal is of great importance in the dexterous control of the EMG prosthetic hand. In this paper, an action force estimation method which is based on the eight channels of the surface EMG (sEMG) and the Generalized Regression Neural Network (GRNN) is propo...

Abnormal resting paraspinal muscle activity has been claimed to be responsible for changes in spinal tissue texture which are detectible by manual palpation. This pilot study investigated whether there was significant electrical activity in paraspinal musculature that was tender and that appeared to have altered tissue texture on palpation. Sixteen healthy volunteers between 18 and 35 years of ...

Biofeedback is a process in which biological information is measured and fed back to a patient and clinician for the purpose of gaining increased awareness and control over physiological domains. Surface electromyography (SEMG), a measure of muscle activity, allows both a patient and clinician to have direct and immediate access to muscle functioning that is not possible with manual palpation o...

This study explored the effects of 5 taste solutions (citric acid, sucrose, sodium chloride, caffeine, and sodium glutamate) versus water on the power frequency content of swallowing submental surface electromyography (sEMG). Healthy subjects were presented with 5 ml of each of 5 tastants and water. Data were collected in 3 trials of the 5 tastants and water by using submental sEMG, which was t...

Surface electromyography (sEMG) signals reflect muscle contraction and hence, can provide information regarding a user's movement intention. High-density sEMG systems have been proposed to measure muscle activity in small areas and to estimate complex motion using spatial patterns. However, conventional systems based on wet electrodes have several limitations. For example, the electrolyte enclo...

Recent research suggests that surface electromyography (SEMG) abnormalities during flexion are highly associated with low back pain, and specific treatments that target these abnormalities are beginning to emerge in the literature. This article describes one such treatment that uses a device called the MyoRackTM to decrease muscle tension in the low back and improve strength and flexibility in ...

–This paper is concerned with studying human ankle movement based on surface electromyographic(sEMG) signals. The sEMG signals were collected from muscles of normal subjects when they moved their ankle flexion-extension. Two types of movement were designed including bending and extending. Analysis of sEMG(surface electromyogram) centered on two features; magnitude of activation & the degree of ...

Surface electromyography (sEMG) is a popular research tool in sport and rehabilitation sciences. Common study designs include the comparison of sEMG amplitudes collected from different muscles as participants perform various exercises and techniques under different loads. Based on such comparisons, researchers attempt to draw conclusions concerning the neuro- and electrophysiological underpinni...

AIM The aim of this study is to prove that facial surface electromyography (sEMG) conveys sufficient information to predict 3D lip shapes. High sEMG predictive accuracy implies we could train a neural control model for activation of biomechanical models by simultaneously recording sEMG signals and their associated motions. MATERIALS AND METHODS With a stereo camera set-up, we recorded 3D lip ...

It is well known that Surface Electromyography is the activity that is being generated when voluntary contraction took place, so in this investigation, the study of Surface Electromyogram (SEMG) signals at different above-elbow muscles were carried out. These signals were easily acquired from surface of skin of the body using non-invasively house design of hardware system and various techniques...
