ABSTRACT Myotherapy intervention in facial aesthetics aims to attenuate wrinkles and signs of aging. The relationship between accentuated muscle contraction during chewing, swallowing speaking the appearance has been suggested by speech-language pathology literature. This study aimed report effect electromyographic biofeedback associated with training swallowing, smiling patterns, speech therap...

Detection of nonlinearity should be the first step before any analysis of nonlinearity or nonlinear behavior in biological signal. The question is which method should be used in each case and which one can best respect the different characteristics of the signals under investigation. In this paper we compare three methods widely used in nonlinearity detection: approximate entropy, correntropy a...

BACKGROUND Conventional intraoperative nerve monitoring, predicated on intermittent stimulation, can predict recurrent laryngeal nerve (RLN) palsy only after the damage has been done. METHODS Fifty-two patients (52 nerves at risk) who underwent continuous intraoperative nerve monitoring (CIONM) for thyroid surgery via vagus nerve stimulation had their electromyographic (EMG) tracings recorded...

This paper reports on our recent research on surface electromyographic (EMG) speech synthesis: a direct conversion of the EMG signals of the articulatory muscle movements to the acoustic speech signal. In this work we introduce a unit selection approach which compares segments of the input EMG signal to a database of simultaneously recorded EMG/audio unit pairs and selects the best matching aud...

Electromyographic (EMG) signal directly represents muscle activity. When recording EMG signals of closely located muscles on skin surface the problem of source separation arises, each acquired channel records signals coming from different muscles [1]. Working on extrinsic finger extensors EI (index) and EDM (little finger) provides a system with muscles that are closely located and independentl...

The purpose of this study was to determine if integrated electromyographic activity recorded from an unexercised muscle during contralateral exercise was dependent upon the contralateral muscle (agonist or antagonist) being exercised and upon the position of the unexercised limb. Twenty normal subjects participated in the study. Electromyographic activity was recorded, using surface electrodes,...

[Purpose] The purpose of this study was to examine the effects of closed kinetic chain exercises (CKCEs) and open kinetic chain exercises (OKCEs) with elastic bands on the electromyographic activity of patients with degenerative gonarthritis. [Subjects] The study subjects were 30 degenerative gonarthritis patients who were divided into a CKCE group (CKCEG, n=10), an OKCE group (OKCEG, n=10), an...

Abstract Hydrogels are a widely used ionic conductor in on-skin electronic and iontronic devices. However, hydrogels dehydrate the open air freeze at low temperatures, limiting their real applications when they attached on skin or exposed to temperatures. Polymer-ionic liquid gels can overcome these two obstacles, but synthetic liquids expensive toxic. In this work, we present an based polyacry...

This paper describes a direct on-line electronic method for determination of the quadrupedal footfall patterns of animals during locomotion. This technique involves the application of a 30 kHz AC carrier signal to a conductive treadmill belt. The time of contact of each paw on the belt is determined by recording the increased conduction of these carrier signals from the treadmill surface throug...
