Since 1995, Blue Valley Physical Therapy has been diagnosing and treating musculoskeletal pathology, working to get the best healing for our patients in the shortest amount of time possible. Now we are excited to add the WAVi EEG brain scan to our medical toolkit, an accurate and proven way to measure brain health and performance.
WAVi is much more than just a brain scan. Wavi is a multifaceted platform that offers practitioners a panoramic perspective of the brain.
“Diagnosing a brain disorder by looking only at symptoms, is analogous to diagnosing a heart condition without looking at an ECG (electrocardiogram) or the heart itself. To diagnose and treat a brain accurately, it is necessary to look at the brain directly. We are now in a new era of neuroscience, one where we can look directly at brain function in real time, with no risks and no side effects, non-invasively and find the true source of so many disabilities.”
-Aditi Shankardass, Head of Clinical Neurophysiology, Harvard University
Blue Valley Physical Therapy’s 30 minute, EEG Brain Scan is a highly reliable way to test for brain health and performance. Our Brain Scans provide objective information that can be used to aid in the diagnosis of:
“Concussions cause measurable changes in the electrophysiological markers of brain activity. Concussed participants often pass clinical tests while still displaying electrophysiological deficits. EEGs may constitute a useful adjunct in determining when to return to play for injured athletes, thereby preventing early return that may be a cause for prolonged post-concussive symptomology.”
(Clayton, et al., In-Clinic Event Related Potentials for Sports Concussion: A 4-Year Study, Children’s Hospital Colorado; University of Colorado School of Medicine; University of Colorado Dept. of Athletics; WAVi Co.)
EEG Brain Scans can visually demonstrate changes in brain health following concussion. Here is a heat-map visual representation of three players, before and after a concussion, as well as at the end of the season.
Colors towards the red spectrum reflect higher brain voltages, whereas the blue colors reflect lower brain voltages. Notice the significant shift from reds to blues from the left row (baseline) to the second row, after the player suffered a concussion.
Note that player 7 had not yet recovered at the end of the season.
(Base = baseline, CN = after concussion, RTP = return to play, END = end of season)
Depression and Anxiety
“According to studies, moderately large effect sizes are seen in EEG evaluation of F3/F4 brain waves suggesting that both depression and anxiety are meaningfully related to relative right-sided resting frontal EEG asymmetry.”
(Journal of Abnormal Psychology, 2006, Vol 115)
“General changes in theta and beta power coincide with previous studies finding about 90% sensitivity for the presence of a raised theta/beta ratio in ADHD patients versus normal children, adolescents, and adults.”
(S. Snyder & J. Hall, Journal of Clinical Neurophysiology, Oct. 2006; Brain Electrical Activity and ADHD)
What is an EEG?
An electroencephalogram (EEG) is a medical test used to measure the electrical activity of neurons. An EEG tracks and records brainwave patterns as well as measures speed, voltage and reaction time.
Brainwaves: (click here)
Our brain is made up of a complex cellular network of around 86 billion neurons, surrounded by even more neuroglia cells (cells that support the neurons). Each neuron is connected to around 10,000 neighboring neurons, with multiple connection points between each pair. These connection points are called synapses. It is estimated that a signal neuron will have around 1 trillion synaptic connections with its 10 thousand neighbors.
Messages from neuron to neuron are sent via an electrochemical signals. The signal from one neuron to another is too small to detect, but when there are synchronized electrical pulses from groups of neurons, a detectable brainwave is produced. Brainwaves are used to communicate our thoughts, emotions and behaviors throughout the brain.
“An EEG can detect brainwaves through sensors placed on the scalp, giving us the ability to see brain function and health in real time.”
Our EEG is performed in 30 minutes, and involves several different challenges to brain function while wearing a helmet that precisely records electrical activity emitted by the brain.
Preparing for the test:
- Do not braid your hair as this may interfere with the contact of the electrodes.
- Do not wear earrings.
- Get a good night's sleep.
- Avoid alcohol the night before or caffeine the day of the test.
- If you are on any medications, then take them as you normally do.
Does the test hurt?
No, there is no pain involved with EEG scans.
Will you be able to diagnose me as having a concussion, depression, ADHD, or anxiety?
No. The data provided by the EEG provides your physician with a tool that is highly sensitive and specific for the diagnoses that we are currently using it to test for. However, EEG measurements are one of many tools a physician will use in determining a final diagnosis.
Are there any side effects to this testing?
No, this device is only measuring your brain activity, and there are no side effects.
Cost of the EEG Brain Scan:
Special pricing is available for groups of 10 or more. Contact Ryan Klusman at firstname.lastname@example.org for more information about group rates.
What other testing goes along with the Brain Scan?
Based on the results of the brain scan, we may ask you to take other tests or questionnaires that will further aid the medical team in making a diagnosis and providing the best possible treatment.
Do I or my physician get the results?
- Yes, we can provide you with the results and/or fax them to your doctor.
- Based on the results from the scan, we may recommend that you follow up with a physician.
- If you need a physician recommendation, then we can help with that too.
