Electromyography is the measurement and analysis of the electrical activity in skeletal muscles. This technique is useful for diagnosing the health of the muscle tissue and the nerves that control them. [8] EMG measures action potentials, called Motor Unit Action Potentials (MUAPs), created during muscle contraction.
Surface EMG is a non-medical procedure used to assess muscle activation by several professionals, including physiotherapists, kinesiologists and biomedical engineers. In computer science, EMG is also used as middleware in gesture recognition towards allowing the input of physical action to a computer as a form of human-computer interaction .
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
In an electromyoneurography procedure, recording of the muscle is done by insertion of a needle. The recordings are taken when the muscle is at rest and when the muscle is contracting; the muscle will contract based on the directions of the one performing the test (instructing the patient to move certain body parts in certain directions forming ...
Several alternative procedures exist for testing facial nerve integrity. Electromyography, Acoustic reflex testing (formerly the gold standard), MRI, CT scanning, transcranial magnetic stimulation, blink reflex tests, and maximal/minimal stimulation tests may also be used to assess the viability of the nerves. Currently, however ...
This procedure may be performed either under general anesthesia or under local anesthesia if patient interaction is required for functional cortical mapping. Electrodes are then surgically implanted on the surface of the cortex, with placement guided by the results of preoperative EEG and magnetic resonance imaging (MRI). Electrodes may either ...
Nerve conduction studies along with needle electromyography measure nerve and muscle function, and may be indicated when there is pain and/or weakness in any extremity which could indicate spinal nerve compression or some other neurologic injury or disorder.
Structural magnetic resonance imaging (structural MRI) of a head, from top to base of the skull. The first chapter of the history of neuroimaging traces back to the Italian neuroscientist Angelo Mosso who invented the 'human circulation balance', which could non-invasively measure the redistribution of blood during emotional and intellectual activity.
