Lack of variability over time of the percent alpha trend (PAV) is associated with poor clinical outcomes. The daily PAV scores are graphed for those brain injured patients who eventually had a good outcome (top panel) and those that had a poor outcome (bottom panel). The PAV scores tend to remain good or improve day by day in those patients with a good outcome, whereas they remain poor or worsen day by day in those patients with a bad outcome.
