A nerve conduction study is a medical diagnostic test commonly used to evaluate the function, especially the ability of electrical conduction, of the motor and sensory nerves of the human body.
Electromyography is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram.
Electroencephalography is an electrophysiological monitoring method to record the electrical activity of the brain. It is a noninvasive investigation, with the electrode surface placed along the scalp, although invasive electrodes are sometimes used, as in electrocorticography.
A visual evoked potential is an evoked potential caused by a visual stimulus, such as an alternating checkerboard pattern on a computer screen. Responses are recorded on evoked potential machine that are placed on the back of your head and are observed as a reading on an electroencephalogram (EEG).
Brain stem evoked response audiometry in clinical practice. … It is a valid method of dealing with suspected malingerers and those who cannot respond to standard audiometric techniques. BERA has been helpful in determining the threshold of hearing in these patients.
Somatosensory Evoked Potential test (SEP) An somatosensory evoked potential test (SEP) studies the relay of body sensations to your brain and how the brain receives those sensations. A stimulating electrode is placed on your arm or leg, and it generates an electrical signal.
Pulmonary function test is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment.
Electrocardiography is the process of producing an electrocardiogram, a recording – a graph of voltage versus time – of the electrical activity of the heart using electrodes placed on the skin.
