Clinical neurophysiology is a branch of medicine that analyses the central and peripheral nervous systems using bioelectrical activity recordings. Electromyography and nerve conduction tests, Electroencephalography, Evoked potentials, and Polysomnography are among the most common diagnostic modalities used. Clinical neurophysiology is a new subspecialty of neurology and physiology in Iraq. Clinical neurophysiology is still underrepresented in medicine, and there is a paucity of useful understanding and education in this discipline. A survey structure by using google form is created and 330 participants were involved in the study from different cities in Iraq and different grades. The data shows that the majority of participants (70%) enrolled in the study are partially aware of the clinical neurophysiology, and Approximately (90%) of participants answer the basic knowledge question about the EMG uses truly, and the higher true answer rate was among the specialist doctor, in contrast to the medical students who get the lower right answers rate. Nevertheless, the basic question about the NCS gets only (37%) right responses and the lowest rate of true response was among the rotator residents. On the other hand, the question about the EEG principle was truly answered in (78%) of participants, and same as EMG response, the higher rate was for specialist doctors and the lowest rate was for medical students. Furthermore, the question of VEP uses was solved correctly in (55%) of persons only with the lowest response rate among medical students. In addition to this, (71%) of participants answered the question of MND diagnosis correctly with the same pattern of response which is higher for the specialists and lower for the medical students. Finally, as it was expected the best response was for those of neurological related specialties that include neurology, neurosurgery, and neurophysiology.
