The aim of the study was to investigate the possibility of using infrared (IR) thermography for assessing muscle fatigue during low effort. Three tests at constant levels of load 5, 15 and 30% of maximum voluntary contraction (MVC) lasting 5 min each were performed on a group of 10 men. Temperature and electromyographic (EMG) signal were registered from biceps brachii (BB). Analysis focused on ...

Eighty untreated patients suspected to have leprosy were submitted to neurophysiological examination and later compared with the clinical diagnosis. Among the patients who had leprosy confirmed, 98% had EMG abnormalities. Motor and sensory amplitude reduction was the earliest and the most frequent abnormality. Low conduction velocity of the ulnar nerve across the elbow was present in over 55% o...

OBJECTIVE To document electromyographic (EMG) changes in thyrotoxic patients, and to categorize the type of myopathic process in thyrotoxicosis. METHODS This case control study was designed to show the EMG changes in thyrotoxic patients and to compare these findings with that of normal aged matched controls to show the significance of these changes in thyrotoxic patients. Student`s test was a...

The objective of the study was to assess the effectiveness of using electromyographic biofeedback in the early stages of rehabilitation after meniscal repair. In this randomised, controlled, parallel group study, the evolution of patients with meniscal lesions treated by meniscal suture who received (study group, n = 33) or did not receive (control group, n = 31) electromyographic biofeedback a...

We investigated the electromyographic activity (EMG) of flexor and extensor muscles with different hand positions in patients with essential (ET) and parkinsonian (PD) tremor. Using a previously developed bootstrap method and standard cross-spectral analysis, we performed statistical tests to assess the effect of hand position on: (1) the frequency of the EMG; and (2) the phase between the EMGs...

Electronic apppliances are increasingly a part of our everyday lives. In particular, mobile devices, with their reduced dimensions with power rivaling desktop computers, have substantially augmented our communication abilities offering instant availability, anywhere, to everyone. These devices have become essential for human communication but also include a more comprehensive tool set to suppor...

Abstract The reconstruction of the structure biological tissue using electromyographic (EMG) data is a non-invasive imaging method with diverse medical applications. Mathematically, this process an inverse problem. Furthermore, EMG are highly sensitive to changes in electrical conductivity that describes tissue. Modeling inevitable measurement error as stochastic quantity leads Bayesian approac...

Purpose The purpose of this study was to investigate the effects prosthetic interventions in patients with Kennedy Class ? (unilateral missing posterior teeth) on mastication predominance.Methods subjects comprised II and healthy dentate volunteers (HD group). were asked freely chew test foods (chewing gum, beef jerky, peanuts). Electromyographic activity bilateral masseter muscles recorded twi...

Twenty two patients with obstructive defecation were recruited for relaxation training by domiciliary self regulatory biofeedback. Each patient served as his or her own control for anorectal and proctographic assessments. Biofeedback training improved the obstructive symptoms of the patients and showed significant change in various parameters related to the obstructive defecation syndrome. As e...
