Vertigo being a very common disease is also a particularly confusing one because of the words used by the patient to describe it. It is also confusing because of the battery of tests that has to be used to establish its cause and it is all the more confusing because this one symptom can be due to a wide range of different underlying pathologies. The clinical tests like Electronystagmography and Cranio corpography test are very helpful in the diagnosis of vertigo.
Electronystagmography provides a permanent recording of a nystagmus and it can detect nystagmus which is not readily visible on examination otherwise. It helps to differentiate between the peripheral or central origin of vertigo and to support diagnosis and to calculate canal paresis. Cranio-corpography is cheap and easily performed the outpatient procedure when compared to the more expensive computerized dynamic posturography which is unimaginable for some patients due to the costs associated with it.
Cranio-corpography is highly efficient in detecting defects in the vestibule-spinal pathway and peripheral vestibular disorder if properly performed. CranioCorpoGaphy or CCG is a medical analysis and measurement procedure. It was developed in 1968 by German neurootologist Claus-Frenz Claussen. Cranio corpography tests give a photographic representation of the patient's movement patterns as he performs the standing and stepping tests known as the Unterberger and Romberg’s test respectively.
Sensations of rotation or dizziness and nausea are the subjective symptoms characteristic of vertiginous syndromes; nystagmus and oscillations of the head and body are the objective signs. Craniocorpography is a method for recording and measuring these oscillations rapidly and inexpensively it provides easier diagnosis, follow-up, and measurement of therapeutic effectiveness.
