Electromyogram or EMG signal is a very small signal; it requires a system to enhance for display purpose or for further analysis process. This paper presents the development of low cost physiotherapy EMG signal acquisition system with two channel input. In the acquisition system, both input signals are amplified with a differential amplifier and undergo signal pre-processing to obtain the linear envelope...
The surface electrohysterographic (EHG) signal represents the bioelectrical activity that triggers the mechanical contraction of the uterine muscle. Previous work demonstrated the relevance of the EHG signal analysis for fetal and maternal monitoring as well as for prognosis of preterm labor. However, for the introduction in the clinical practice of diagnostic and prognostic EHG techniques, further...
This paper presents the results of a series of experiments aiming at the optimisation of vital sign monitoring using textile electrodes to be used in a swimsuit. The swimsuit will integrate sensors for the measurement of several physiological and biomechanical signals; this paper will focus on ECG and respiratory movement analysis. The data obtained is mainly intended to provide tools for evaluation...
Functional electrical stimulation (FES) can restore volitional motion of patients with neurological injuries or diseases using electrical stimulation of nerves innervating the muscles to be controlled independently. The flat interface nerve electrode (FINE) enables the selective control of different muscles at the same time. In addition, multiple contact electrode designs allow selective recording...
Six subjects with profound facial paralysis were tested to determine the feasibility of restoring functional blink via electrical stimulation of the orbicularis oculi muscle (OOM) without also evoking painful sensations. Stimulation of the paretic eyelid was triggered by EMG detection of blink in contralateral healthy OOM to deliver charge during inhibition of the levator palpebrae antagonist. Transcutaneous...
