Head impact analysis and comparison system

A computer system configured to analyze head impact events, comprising:

• a sensor configured to be worn on the head of a user, the sensor configured to detect a head impact parameter;
• a processor;
• and
• a memory, the memory in communication with the sensor, the memory further having stored programming instructions operable by the processor to:
• receive the impact parameter data related to an impact parameter for an impact event experienced by the head of a user;
• compare the impact parameter data to previously stored impact parameter data in a data store, wherein the previously stored impact parameter data is associated with prior impact events and is organized into a plurality of categories in accordance with a plurality of outcomes associated with the prior impact events;
• and
• generate an association between the impact event and one or more of the prior impact events including by associating the impact event with one of the plurality of categories.
