Computerized Dynamic Posturography (CDP)

Vestibular Disorders

The purpose of the CDP test is to measure your overall postural stability. It consists of three short tests that assess the ability of the body’s sensory systems (touch, vision, and vestibular) to accurately receive information about the environment, the ability of the brain to use the information, and the ability of the motor system to perform the necessary actions to maintain balance. During the test, the patient will stand inside the CDP machine while wearing a safety harness to prevent falling. The therapist will instruct the patient to stand quietly and follow the instructions as best as possible. During the course of the three tests, the patient will be asked to maintain balance during various conditions, such as with eyes closed and with eyes open while the walls move.
