Jeffrey Balzer




Jeffrey Balzer, PhD, is director of clinical operations and staff clinical neurophysiologist at the Center for Clinical Neurophysiology and director of the Cerebral Blood Flow Laboratory at the University of Pittsburgh Medical Center.

His current research interests range from the utilization of genetic biomarkers for the prediction of delayed cerebral ischemia in subarachnoid hemorrhage to the use of blood flow measures in mild head injury and concussion to vagal nerve stimulation to control cardiac arythmias. Dr. Balzer received his undergraduate education at the University of Pittsburgh, where he also pursued a graduate education and a PhD in behavioral neuroscience.

He is also the secretary/treasurer of the American Board of Neurophysiological Monitoring and is on the board of directors of the American Society of Neurophysiological Monitoring. He has published 71 refereed articles and 14 book chapters

Research Activities

In collaboration with colleagues from the Physical Activity and Weight Management Research Center, Dr. Balzer has been investigating and developing feasible strategies to decrease the burden of cardiovascular disease. He is currently investigating the novel health benefits of using a sit-stand desk. Dr. Balzer is quantifying the effects of using a sit-stand desk on blood pressure (the most common modifiable risk factor for heart disease), arterial stiffness measured by pulse-wave velocity (a global measure of cardiovascular health), and cerebrovascular blood flow velocity (blood flow in the brain that is related to cognitive function and brain health). This research will greatly contribute to the understanding of potential health benefits of sit-stand desks.

The clinical implications of these acute health benefits, if confirmed, are significant. Firstly, patients with cardiovascular disease risk factors (hypertension, arterial stiffness, high risk for stroke or cognitive decline) could have therapeutic benefit from being ‘prescribed’ a sit-stand desk with a transitioning routine. Moreover from a public health perspective and among healthy working adults, decreasing the daily exposure to high blood pressure, arterial stiffness, and reduced cerebrovascular blood flow caused by prolonged sitting at work, could reduce the development of cardiovascular disease in the working population.
