Computerized Dynamic Posturography The Balance Quest Testing Platform is the only truly dynamic platform available. When the platform center support is released from a static position, the Balance Quest platform floats on a spring suspension, allowing
dynamic motion with 6 degrees of freedom of
movement. This dynamic freedom more accurately mimics natural conditions which disturb proprioceptive information.
The platform allows linear movement in X (forward/
backward), Y (side to side) and Z (up/down) planes.
There are also three axes of angular movement
allowed: Yaw (twist clockwise / counterclockwise), Pitch (tilt forward / backward) and Roll (tilt left / right).
Balance Quest software measures the center of pressure in the X, Y, and Z planes plus pitch and roll axes for unparalleled information about the direction and amplitude of sway. This information allows you to identify fall risk factors, work related dysequilibrium and malingering. The Balance Quest can also assist with assessing whether a patient's balance disorder is due to misinformation or misinterpretation of sensory and motor inputs and his/her ability to suppress information that is inaccurate.
Features
• Sensory Organization Test (SOT) with 6 conditions
• Three degrees of freedom with pneumatic control for unstable platform
• Rehabilitation protocols for vestibular and orthopedic patients
• Four-point safety harness to catch patients in the event of falling
• Limit of Stability Test (LOS) that analyzes the patient's ability to lean forward, backward, and to the sides in relation to standing stable in the center position

Options
The Balance Quest Platform Full Field Optokinetic Projector (OKN) is used for conditions C &
F of the SOT test protocol as well as during rehabilitation to strengthen equilibrium function. This option works best when a darkened room can be dedicated to Balance Quest posturography. The Optokinetic stimulation interferes with the VOR (vestibular - ocular reflex) by means of visual perturbation, which in turn may confound postural control.
Virtual Environment Glasses (VR Glasses) can present the patient with a variety of computer controlled stimuli within a virtual reality environment while on the Balance Quest Platform. Stimuli may appear sway referenced and/or optokinetic in nature. The VEG are ideal for conditions C & F of the sensory organization test and for use during rehabilitation when a darkened room is not available. Visual stimuli the size of a 52-inch television screen is produced in pitch or roll directions to give a sense of rotation.
The Subjective Visual Vertical (SVV) device permits an objective measurement of vertical as perceived by the subject; especially for patients with otolith loss.
The patient can orient the laser to his/ her perceived vertical while the readout gives the angle from true vertical. During rehabilitation, the Balance Quest platform is tilted and the laser stripe is aligned with the platform. As the platform is gradually returned to its stable position, the patient is retrained to compensate for the unilateral loss. |
