The purpose of this study was to investigate the influence of anteroposterior postural change on electromyography (EMG) activity in the lateral pterygoid muscle. Subjects consisted of 7 patients attending this hospital for close examination. The inferior heads of the lateral pterygoid and masseter muscles were chosen as evaluation sites. For the EMG recordings, the test movement was opening and...

The study purpose was to analyse the peak EMG at five upper-body muscles during four different jab techniques in youth boxers.
 Materials and methods. Male national-level boxers (n=7) were assessed for electromyography (EMG) of anterior deltoid (AD), biceps brachii (BB), triceps (TB), flexor carpi radialis (FCR), upper trapezius (UT) while performing techniques: long-range targeting head (...

BACKGROUND We have previously shown that nasal pressure support ventilation (nPSV) can lead to an active inspiratory laryngeal narrowing in lambs. This, in turn, can limit lung ventilation and divert air into the digestive system, with potentially deleterious consequences. On the other hand, nasal high-frequency oscillatory ventilation (nHFOV) is particularly attractive in newborns, especially ...

Torque and electromyographic (EMG) responses to sinusoidal rotations of the foot were measured. The frequency range of the movements was 0.5 Hz to 15 Hz at amplitudes ranging between 1 and 10 degrees. At frequencies above 7 Hz, the EMG activity did not follow individual foot rotation cycles. The EMG activity was inhibited whenever the peak torque was large with respect to the first cycle peak ...

This article gives an overview of the EMG-UKA corpus, a corpus of electromyographic (EMG) recordings of articulatory activity enabling speech processing (in particular speech recognition and synthesis) based on EMG signals, with the purpose of building Silent Speech interfaces. Data is available in multiple speaking modes, namely audibly spoken, whispered, and silently articulated speech. Besid...

An accurate and computationally efficient means of classifying electromyographic (EMG) signal patterns has been the subject of considerable research effort in recent years. Quantitative analysis of EMG signals provides an important source of information for the diagnosis of neuromuscular disorders. Following the recent development of computer-aided EMG equipment, different methodologies in the ...

BACKGROUND There is currently no consensus on the best way to localize muscles in the forearm for botulinum toxin (BTX) injection. We devised a study to compare electromyography (EMG) with local stimulation through a cannula for localizing forearm muscles for botulinum toxin (BTX) injection, and for predicting the risk of unwanted weakness in non-target muscles. METHODS In 12 patients with fo...
