CONTEXT Mandibular movements (MM) are considered as reliable reporters of respiratory effort (RE) during sleep and sleep disordered breathing (SDB), but MM accuracy has never been validated against the gold standard diaphragmatic electromyography (EMG-d). OBJECTIVES To assess the degree of agreement between MM and EMG-d signals during different sleep stages and abnormal respiratory events. ...

This study investigated whether the modular control of changes in direction while running is influenced by perturbations to balance. Twenty-two healthy men performed 90° side-step unperturbed cutting manoeuvres while running (UPT) as well as manoeuvres perturbed at initial contact (PTB, 10 cm translation of a moveable force platform). Surface EMG activity from 16 muscles of the supporting limb ...

Abstract Mice are excellent model organisms to study human diseases as a handful of genetic tools available manipulate their genome simulate most diseases. Since the mice is similar that humans (only less than 10 among approximately 4,000 genes studied different), can be used tool molecular pathogenesis and develop novel therapeutic interventions. Although mouse models have been in developing b...

background: the time and frequency features of motor unit action potentials (muaps) extracted from electromyographic (emg) signal provide discriminative information for diagnosis and treatment of neuromuscular disorders. however, the results of conventional automatic diagnosis methods using muap features is not convincing yet. objective: the main goal in designing a muap characterization system...

Upper limb movement classification, which maps input signals to the target activities, is a key building block in control of rehabilitative robotics. Classifiers are trained for system comprehend desires patient whose upper limbs do not function properly. Electromyography (EMG) and Electroencephalography (EEG) used widely classification. By analysing classification results real-time EEG EMG sig...

In the development of robot-assisted rehabilitation systems for upper limb rehabilitation therapy, human electromyogram (EMG) is widely used due to its ability to detect the user intended motion. EMG is one kind of biological signal that can be recorded to evaluate the performance of skeletal muscles by means of a sensor electrode. Based on recorded EMG signals, user intended motion could be ex...

During running, psychologic and physiologic changes are manifested in the perception of effort, muscle properties and movement strategies. The latter two aspects are expressed as changes in electromyographic (EMG) activity. This paper tests the hypothesis that the EMG signals change in a systematic way during a run and that these changes are related to the effort level of the runner. Fifteen fe...
