Electrodiagnosis


Prof. Dr. Kamuran Yücel Electrophysiology Laboratory

Purpose of Establishment

Electromyography (EMG) examination

  • Guiding the type of treatment to be chosen by determining the degree of damage in the affected nerve and level in nerve injuries and compressions
  • To determine the level of lumbar and cervical disc herniation
  • Takes important part in physical therapy and rehabilitation since it serves as an adjunctive method for the diagnosis of muscle and spine disorders by determining the diseases causing nerve dysfunction (i.e. metabolic diseases: diabetes, renal disease).

Working Days
EMG laboratory works on an appointment calendar and serves in weekday between 08:30-12:30.

What We Do
EMG examination is composed of two separate steps. At the first step, electrical transmission function of the nerves is examined by applying direct current at low intensity so as not to cause excessive inconvenience for the patient. For this purpose, low intensity electric current is applied to the finger tips and skin above the nerves and the current is measured with computerized devices from another part of the skin or the nerve. This reveals whether or not the nerve functions well. At the second step, disposable needle-shaped sterile fine wire electrodes are inserted into the muscle tissue and the analysis of the electrical activity observed on the EMG screen suggests whether the examined muscle or the nerve supplying the muscle is diseased or not.





Routine Examinations:

  1. Upper and lower extremity nerve conduction velocity
  2. Needle EMG examination
  3. H-Reflex examination
  4. F-Response examination
  5. Botulinum injections guided by EMG

Special Examinations:
  1. Somatosensorial evoked potentials (SEP)
  2. Sympathetic skin response

While coming for the examination:
  • The patient is recommended to have a full stomach before examination.
  • Because the test is generally performed on arms and legs, loose-fitting comfortable clothing must be preferred. Women patients are recommended not to wear tights.
  • Hands and the feet must be cleaned before the test and creams or other cosmetic products must not be used.
  • Jewelries on the hands and arms (such as rings, bracelet or watch) must be removed before the test as these materials may affect the procedure.
  • There is no objection for taking regular medicines, if any.
  • However, patients taking blood thinning medicines (aspirin, coumadin) must inform their doctor beforehand.
  • Patients with pacemaker implants should inform their doctor before the test.
  • The duration of EMG examination may vary; however, it generally takes between half an hour and 1 hour.

How to Apply?
Among patients admitted to our general or specialized outpatient clinic, those who are recommended by the attending doctor to undergo the procedure as an adjunctive tool in diagnosis are directed to EMG laboratory.
