Traumatic Brain Injury and Its Effects on Balance

Traumatic brain injuries (TBI) can have a serious impact on many aspects of the human body's ability to function normally, including a person's ability to maintain balance. A TBI is defined as brain damage caused by a severe trauma to the head and can cause a large number of problems. Balance impairments (also sometimes called balance dysfunctions or balance disorders) are common for some following a TBI. One unexpected aspect of this problem is that compared to other medical conditions that can cause balance impairments (such as strokes or seizures), there has been relatively little study into the effects of brain injury on balance. Fortunately however, this is changing.

Symptoms of Balance Disorders

Balance disorders occur, at least temporarily, in nearly all people who have suffered a TBI. This instability can exist even when neurological tests do not detect any problems.

Symptoms common to balance impairments can include:

* Feeling dizzy, lightheaded, woozy or a sensation of spinning (vertigo)

* Burred vision

* Falling or unsteady gait (feeling of falling)

Diagnosing Balance Disorders

Maintaining balance is a complex multifunctional process that involves interplay between three systems:

* Vestibular system (the inner ear balance organs)

* Visual system (eyes)

* Somatosenory system (joint and muscle receptors or sensors)

Normally, the brain receives and processes information about the environment and these systems work together to control balance. The primary test that is used to assess balance impairment is the Sensory Organization Test (SOT), which is conducted by evaluating each of the the three balance systems. Balance Impairment and Severity of Traumatic Brain Injury

The severity of TBI is determined using several measures such as:

* Glasgow Coma Test

* Length of unconsciousness (time in a coma)

* Length of post-traumatic amnesia (PTA)

For TBI patients beginning rehabilitation, there is a significant relationship between TBI severity and degree of sitting and standing balance impairment. Patients with more severe TBI ratings also have more impaired balance ratings.

Recovery from Balance Disorders Caused by Traumatic Brain Injury

A study at Wayne State University found that the degree of balance impairment for brain-damaged patients (specifically sitting balance impairment), measured at time of admission to rehabilitation can predict the Functional Independence Measure (FIM) at discharge. FIM illustrates how well patients recovering from a TBI can live independently after they are discharged. The relationship between balance impairment, brain injury severity, the prognosis for recovery from a TBI is underscored by this study.

For cases of mild traumatic brain injury in which there was no loss of consciousness and no clinically detectable problems, balance impairments (as measured by performance on the Sensory Organization Test), usually last from 3 to 10 days. However, subtle balance impairments that are harder to detect, such as abnormally high reliance on vision for maintaining balance, can persist for months or years.

Individual treatment plans for balance disorders may include balance retraining exercises, general exercise, and certain drugs. Recovery takes time and recovery times vary. Some brain-injured people require assistance for years. If you have suffered from a traumatic brain injury, you may wish to contact an experienced TBI attorney to help you assess your claim and gain compensation for your medical expenses, future medical care, and the pain and suffering that brain damage and brain injury can cause.
