Computerized Dynamic Posturography
Computerized Dynamic Posturography (CDP) is a supplemental test used in conjunction with other balance tests. CDP can reveal whether an individual’s balance disorder is a result of sensory inputs, motor control or central adaptive impairments. CDP is commonly used to assess the risk of fall and impairment to the balance system following an impact to the head, such as a concussion.
Balance control relies on three sensory inputs: vestibular (inner ear), somatosensory (feet, ankles, joints), and vision. These sensory inputs send signals to the brain to drive and control our motor system. The signals provide cues that indicate factors, such as the direction of head turn, or the texture and slope of the walking surface (e.g., uphill on concrete).
During CDP testing, a series of tests are administered to evaluate a patient’s ability to maintain balance under varying conditions. Some tests are designed to simulate different conditions (e.g., walking on an incline) that patients encounter in every day life, while others are designed to determine the source of the patient’s balance problem. The patient wears a harness during this test to avoid injury from falling.
CDP testing is provided at DENT Neurologic Institute in the Dizziness & Balance Center. Once we have a clearer picture of your vestibular system, Hearing Evaluation Services (HES) can make a proper diagnosis, and make recommendations to correct or rehabilitate your imbalance.
