The Neurophysiology Laboratory

Neurophysiologic diagnostic examinations provide useful information in assessing involvement of the nervous system secondary to systemic diseases, like Diabetes Mellitus and Chronic Renal Failure. This procedure is done in the Neurophysiology Laboratory. Chong Hua Hospital houses a state of the art electrodiagnostic equipment which has the capability to test evoked potentials, nerve conduction studies and electromyographic (EMG) examinations.

The special preparation needed for the following procedures:

Electroencephalogram (EEG)
  • A day before your scheduled procedure, you are advised to:
    1. Sleep late (12mn) and wake up early (3am).
