EMG activated robotic arm for amputees

2018 2nd International Conference on Inventive Systems and Control (ICISC), 2018
Amputation is the removal of limb by trauma, medical illness, or surgery. A transplant or prosthesis is the only option for recovering the loss. This issue can be solved by, measuring muscle activation via electric potential, referred to as electromyography (EMG), has traditionally been used for medical research and diagnosis of neuromuscular disorders.

Corticomotoneuronal postspike effects in averages of unrectified EMG activity

Journal of Neurophysiology, 1989
1. Spike-triggered averaging (SpTA) of rectified electromyograms (EMGs) in awake monkeys is recognized as an effective means of establishing causal relations between cortical/cell discharge and muscle activity. The appearance of postspike facilitation (PSF) in averages of rectified EMG activity is interpreted as evidence of an underlying excitatory ...

Quadriceps Concentric EMG Activity Is Greater than Eccentric EMG Activity during the Lateral Step-Up Exercise

Journal of Sport Rehabilitation, 2000
Purpose:To analyze vastus medialis obliquus (VMO) and vastus lateralis (VL) muscle activity during the concentric and eccentric phases of a lateral step-up exercise.Design:Repeated-measures. Dependent variable: the integrated electromyogram measured as a percentage of the maximal voluntary isometric contraction of the VMO and VL muscles.

Neuromuscular organization and regional EMG activity of the pectoralis in the pigeon

Journal of Morphology, 1993
AbstractIn order to improve our understanding of the neuromuscular control of the most massive avian flight muscle, we studied the innervation pattern of the pigeon pectoralis. Nine primary branches from the rostral trunk and nine to ten branches from the caudal trunk of the pectoral nerve were identified by microdissection in ten pigeons.

Active surface EMG probe and contour follower

Electroencephalography and Clinical Neurophysiology, 1981
Simple and reliable electronic equipment to detect and process EMG surface signals is described. A first stage of differential amplification built upon the electrodes is connected by a multiple cable to a second unit for further amplification, full wave rectification and integration.

EMG activity during positive-pressure treadmill running

Journal of Electromyography and Kinesiology, 2014
Success has been demonstrated in rehabilitation from certain injuries while using positive-pressure treadmills. However, certain injuries progress even with the lighter vertical loads. Our purpose was to investigate changes in muscle activation for various lower limb muscles while running on a positive-pressure treadmill at different amounts of body ...

EMG activity as a marker for intraoperative awakening

2019
Objective: Intraoperative awakening is a rare event with considerable risks for the patient due to sudden movements. A number of methods have been proposed to monitor depth of anesthesia, such as the Bispectral Index (BIS) and the Analgesia Nociception Index (ANI). In a pilot study, we had shown, that[for full text, please go to the a.m. URL]

Changes in Diaphragmatic EMG Activity during Sleep in Space

American Review of Respiratory Disease, 1993
Abstract It remains unknown how increased upper airway resistance (UAR) during sleep could be a function of gravity. We therefore conducted quantitative evaluation of the gravitational influence on diaphragmatic EMG activity (EMGdi) in an astronaut to estimate the effect of UAR in space. EMGdi was recorded by paired surface electrodes

EMG Activity within the Pharynx during Speech Production

Journal of Speech and Hearing Research, 1974
Electromyography (EMG) of the superior and middle constrictor muscles was recorded during phonated and whispered productions of the vowels /i/ and /a/ and the stop consonants /p/ and /b/ in VCVCV trisyllables. Lower levels of EMG activity were consistently associated with production of the voiced consonant /b/ than with comparable productions of the ...

Response of genioglossus EMG activity to passive tilt in men

Journal of Applied Physiology, 1993
Increased blood pressure (BP) leads to inhibition of respiratory activity of hypoglossal nerve in anesthetized cats, implying that arterial baroreceptor activity may inhibit upper airway motor outputs. We examined the effect of passive tilt on upper airway muscle activity in men under the assumption that changes in degree of tilt would change local ...
