a special recording technique that detects electric activity in muscle Patients are sometimes offered a type of biofeedback called EMG training, in which they learn to control muscle tension in the face, neck, and shoulders
An insertion of needle electrodes into muscles to study the electrical activity of muscle and nerve fibers It may be somewhat painful to the patient Helps diagnose damage to nerves or muscles
Electromyography is the recording of electrical currents generated in an active muscle using an instrument called an electromyogram (EMG) EMG recordings can be used to ascertain causes of muscular weakness, paralysis, involuntary twitching, and abnormal levels of muscle enzymes; EMGs can also be used as part of biofeedback studies
A special recording technique that detects electric activity in the muscle Migraine patiets are sometimes offered a type of biofeedback called EMG training, in which they learn to control muscle tension in the fact, neck and shoulders
Process of graphically recording the electrical activity of muscle, which normally generates an electric current only when contracting or when its nerve is stimulated. Electrical impulses are shown as wavelike tracings on an oscilloscope and recorded as an electromyogram (EMG), usually along with audible signals. The EMG can show whether muscle weakness or wasting is due to nerve impairment (as in amyotrophic lateral sclerosis and poliomyelitis) or muscle impairment or disease (myopathy)
