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]

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]

There are several types of posturography, each with its own specific applications and methodologies.

Static Posturography[edit]

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]

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]

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]

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]

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.

 ==Overview==
-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 reflects the body's sway and balance. The data collected can provide insights into the functioning of the [[vestibular system]], [[proprioception]], and [[visual system]], all of which contribute to maintaining balance.

 ===Static Posturography===
-Static posturography measures the body's sway while the subject stands still on a platform. It is useful for assessing the baseline balance and postural stability of an individual. The subject may be asked to stand with eyes open or closed, or on different surfaces to challenge the balance system.

 ===Dynamic Posturography===
-Dynamic posturography involves assessing balance while the platform or the environment is moving. This type of posturography can simulate real-life situations where balance is challenged, such as walking on uneven surfaces or during sudden movements. It is particularly useful for diagnosing balance disorders related to the [[vestibular system]].

-CDP is an advanced form of dynamic posturography that uses computer technology to control the platform and analyze the data. It provides a comprehensive assessment of the sensory and motor components of balance. CDP can help differentiate between sensory, motor, and central nervous system causes of balance disorders.

-==Limitations==
+==Sensory Analysis==
-While posturography provides valuable information about balance, it has limitations. It does not directly measure the function of the vestibular, visual, or proprioceptive systems, but rather the integration of these systems in maintaining balance. Additionally, the results can be influenced by the subject's attention, fatigue, and cooperation during the test.
