Posturography is a test that measures and assesses a patient's balance function using a computerised platform. It can be carried out in-clinic and usually takes around 20 minutes.
Posturography involves placing the patient on a platform and measuring their movements. The platform may be static, or it may be dynamic, able to move in response to the patient or carry out a set of standard movements to test the patient’s balance in different situations.
The data obtained produces detailed images and reports, comparing the patient’s responses with what is normally expected for a patient of their age and body shape. Two of the key measurements made are the patient’s centre of gravity (COG) and their centre of pressure (COP).
A posturography is carried out for two types of patients:
The patient stands in an upright position on the platform, with the heels together and the tips slightly apart, forming an angle of about 30 degrees, and with the arms extended. It is important that the patient is relaxed and remains completely silent, since there should be no stimulus that can alter the balance. The specialist will ask the patient to make different movements to register them.
This test diagnoses balance problems, whether of nervous, visual or sensory origin. The main diseases associated with imbalance are:
