Following a traumatic brain injury (TBI), individuals frequently report symptoms such as decreased balance and coordination. Research indicates that balance issues are reported by 30-65% of TBI patients.
Damage to the brain can disrupt communication between the inner ear and eyes, resulting in a sensory mismatch that impairs balance function and may cause dizziness or vertigo.
In some cases, these balance impairments become severe enough to pose a significant risk of falls for patients.
To assess balance and equilibrium in TBI patients, we employ a specialized computerized dynamic posturography test. This test measures the extent of sway and loss of equilibrium experienced by individuals with brain injuries.
By objectively quantifying these parameters, we obtain valuable data that provides evidence of balance-related problems associated with TBI. This information plays a crucial role in guiding the selection of appropriate rehabilitation options, aiming to enhance the patient’s functional improvement and minimize fall risks.
How does it work?
Our computerized balance test is a sophisticated assessment that utilizes specialized equipment and software to evaluate an individual’s balance and postural control. Here’s a general overview of how the computerized balance test works:
- Setup and Equipment: The individual undergoing the test is typically placed on a stable platform or force plate that is connected to a computer system. The force plate measures the person’s body sway and movements during the test. The individual may also wear a safety harness or use handrails for added stability and safety.
- Sensory Conditions: The test involves exposing the individual to various sensory conditions that challenge different aspects of balance control. These conditions can include changes in visual input, such as moving or tilting the surroundings or using virtual reality simulations, altering support surface conditions (e.g., foam or unstable surfaces), or manipulating the visual and vestibular cues.
- Postural Tasks: The individual is instructed to perform specific postural tasks while maintaining their balance on the force plate. These tasks may include standing with eyes open or closed, standing on foam with eyes open or closed, maintaining balance while the platform moves or tilts, or responding to visual or auditory cues. The tasks are designed to assess the person’s ability to integrate sensory information and adjust their posture accordingly.
- Data Collection and Analysis: Throughout the test, the computer system continuously records and analyzes data from the force plate, capturing parameters such as body sway, center of pressure, and postural adjustments. These measurements provide quantitative information about the individual’s balance control, stability, and postural responses under different sensory conditions.
- Interpretation and Results: The collected data is analyzed and interpreted by healthcare professionals, such as physical therapists or neurologists, who are trained in balance assessment. They evaluate the individual’s performance, compare it to normative data or established criteria, and provide a comprehensive assessment of their balance function. The results can indicate areas of balance deficits, strengths, or compensatory strategies used by the individual.
- Clinical Applications: The computerized balance test results guide treatment planning and rehabilitation strategies for individuals with balance impairments due to conditions like traumatic brain injury. The data helps identify specific areas of balance dysfunction and informs the selection of appropriate interventions, exercises, and therapies aimed at improving balance, stability, and postural control.
Overall, computerized balance tests provide objective and quantitative measurements of an individual’s balance abilities under controlled conditions. This information helps clinicians better understand the person’s balance impairments, tailor treatment plans, and track progress throughout rehabilitation.
