Posturography
A method to assess balance and postural control
Posturography is a technique used to quantify postural control in upright stance in either static or dynamic conditions. It is commonly used in clinical settings to assess balance disorders and to evaluate the effectiveness of treatments for such conditions.
Overview[edit | edit source]
Posturography involves the use of a force platform to measure the forces exerted by the feet on the ground. These measurements are used to calculate the center of pressure (COP), which provides information about the body's sway and balance.
Types of Posturography[edit | edit source]
There are several types of posturography, each with its own specific applications and methodologies.
Static Posturography[edit | edit source]
Static posturography measures the body's sway while the subject stands still on a platform. It is used to assess the ability to maintain balance without any external perturbations.
Dynamic Posturography[edit | edit source]
Dynamic posturography involves assessing balance while the subject is subjected to controlled movements or perturbations. This can include moving the platform or providing visual or auditory stimuli.
Computerized Dynamic Posturography (CDP)[edit | edit source]
CDP is a sophisticated form of dynamic posturography that uses a computerized system to control the platform and stimuli. The Equitest system is a common example of CDP equipment.
Applications[edit | edit source]
Posturography is used in various clinical and research settings to assess balance and postural control. It is particularly useful in diagnosing and managing conditions such as:
Sensory Analysis[edit | edit source]
Posturography can also be used to perform sensory analysis, which evaluates how different sensory inputs (visual, vestibular, and somatosensory) contribute to balance. This is often done using the Equitest system, which can isolate and test each sensory component.
