  2. Electrochemical skin conductance - Wikipedia

    en.wikipedia.org/wiki/Electrochemical_skin...

    The resulting Electrochemical Skin Conductances (ESC) for each hand and foot are expressed in μS (micro-Siemens). The test also evaluates the percentage of asymmetry between the left and right side, for both hands and feet ESC, providing an assessment of whether one side is more affected than the other. [11]

  3. Nerve conduction study - Wikipedia

    en.wikipedia.org/wiki/Nerve_conduction_study

    Patient should be advised to avoid applying lotions or creams to the skin, as these substances can interfere with electrode conductivity. [6] [7] [8] The test is non-invasive and can be performed in an outpatient clinic or hospital setting. The nerve conduction study is often combined with needle electromyography. The Department of Health and ...

  4. Electroneuronography - Wikipedia

    en.wikipedia.org/wiki/Electroneuronography

    Electroneuronography or electroneurography (ENoG) is a neurological non-invasive test used to study the facial nerve in cases of muscle weakness in one side of the face (Bell's palsy). The technique of electroneuronography was first used by Esslen and Fisch in 1979 to describe a technique that examines the integrity and conductivity of ...

  5. Electromyoneurography - Wikipedia

    en.wikipedia.org/wiki/Electromyoneurography

    Electromyoneurography (EMNG) is the combined use of electromyography and electroneurography [1] This technique allows for the measurement of a peripheral nerve's conduction velocity upon stimulation (electroneurography) alongside electrical recording of muscular activity (electromyography). Their combined use proves to be clinically relevant by ...

  6. Small fiber peripheral neuropathy - Wikipedia

    en.wikipedia.org/wiki/Small_fiber_peripheral...

    A skin biopsy for the measurement of epidermal nerve fiber density is an increasingly common technique for the diagnosis of small fiber peripheral neuropathy. [13] Physicians can biopsy the skin with a 3-mm circular punch tool and immediately fix the specimen in 2% paraformaldehyde lysine-periodate or Zamboni's fixative. [ 20 ]

  7. Electrodiagnostic medicine - Wikipedia

    en.wikipedia.org/wiki/Electrodiagnostic_medicine

    Using their broader training, physicians in electrodiagnostic medicine, often perform more detailed evaluations which may include laboratory tests, CT or MRI scans, genetic evaluation, biopsy of nerve, skin, or muscle, or perform neuromuscular ultrasound. A more complete listing of disorders and testing can be found under neuromuscular medicine.

  8. Electrodermal activity - Wikipedia

    en.wikipedia.org/wiki/Electrodermal_activity

    Galvanic skin resistance (GSR) is an older term that refers to the recorded electrical resistance between two electrodes when a very weak current is steadily passed between them. The electrodes are normally placed about an inch apart, and the resistance recorded varies according to the emotional state of the subject.

  9. Action potential - Wikipedia

    en.wikipedia.org/wiki/Action_potential

    Several types of channels capable of producing the positive feedback necessary to generate an action potential do exist. Voltage-gated sodium channels are responsible for the fast action potentials involved in nerve conduction. Slower action potentials in muscle cells and some types of neurons are generated by voltage-gated calcium channels.
