Computerized Dynamic Posturography

 

Overview

Computerized Dynamic Posturography (CDP)can help individuals with poor balance or a high risk of falling, such as the elderly, patients with vestibular dysfunction, dizziness caused by inner ear disease, lower limb orthopedic diseases, stroke, Parkinson's disease, and others. The system simulates daily life environments in a immersive virtual environments(IVR) and customizes the training difficulty level, helping patients with vestibular dysfunction to undergo more advanced training.

 

Features Summary

When vertigo occurs, the feeling of spinning can be very frightening for patients. One of the symptoms of vertigo is dysfunction of the vestibular system, which is composed of the inner ear and brain, and is responsible for maintaining balance. When these parts of the body are damaged or inflamed, it can result in dizziness, vertigo, blurred vision, and balance problems leading to falls, among other issues. Therefore, Computerized Dynamic Posturography combines immersive virtual environments system can be used to identify the cause of vertigo and balance dysfunction.

 

Procedure

Sensory Organization Test can objectively evaluate balance function performance using six different scenarios, which involve changing visual environments and standing support. The test explores the three sensory systems related to human body posture and balance: visual, vestibular, and somatosensory, as well as the balance strategies used (ankle and hip joint strategies) and the range of center of gravity movement. Subjects wear shoe covers and stand on a force plate, with their eyes fixed on a screen in front of them, and their hands resting on their thighs. During the experiment, they cannot lift their feet completely off the force plate, and they follow instructions to complete six static balance tests sequentially. These tests include: (1) eyes open with no movement of the ground and virtual screen, (2) eyes closed with no movement of the ground, (3) eyes open with no movement of the ground and movement of the virtual screen, (4) eyes open with movement of the ground and no movement of the virtual screen, (5) eyes closed with movement of the ground, and (6) eyes open with movement of both the ground and virtual screen.

 

Notification

potential risk and complications include:

1.Dizziness, nausea, and in rare cases, seizures or epileptic episodes may occur.

2.Although there are suspension devices available to prevent falls, there is still a risk of the patient leaning forward

   or backward, which is why medical staff may stand behind the patient to provide protection.
