How do I determine an individual's baseline?

Baseline testing is a common topic and especially prevalent in athletics as the topic of preventing, reducing, and returning safely from concussions continues to be critical. It is relatively simple to just perform an initial single test at a given point (intake) and refer back to that data as the "baseline" or normal data, but that is unfortunately not the most accurate way to understand or determine an individual's baseline. A single point taken months in the past may not be a truly accurate representation of that individual's norm. A baseline isn't just one data point, but a range; and consistent, frequent, longitudinal assessment gives a better picture of that than any single point in time. Once enough data has been collected for a baseline to be established, it becomes possible to identify significant and meaningful changes from that baseline in an accurate way.

How does Sparta determine an individual's baseline?

Within the Sparta system, changes from baseline will be highlighted for each individual based on the amount of change. For this, Sparta defines an individual's "baseline" by taking the average of their last 90 days worth of data.  If there is no data within the last 90 days, Sparta will utilize an average of the last 3 scans.
