On February 29th we posted about the “Cut-Off Indicator” for ImPACT(TM) and recovery periods; in that post I had some open-ended questions regarding this information/press release. Apparently these questions were noticed by UPMC and Chuck Finder, formerly of the Post-Gazette, now part of the media relations of UPMC sent me answers.
The answers were written by Brian Lau, co-investigator of the study/paper, here are my questions and below is the actual response sent to me.

- What did each individual do for management of the concussion in the two days?
