UPMC Responds to TCB Questions

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.

  1. Why would you neurocognitive test anyone with symptoms, while still recovering?
  2. Are the numbers based upon the ImPACT “norms” or a baseline calculation?
  3. Is this experiment repeatable with other measures?
  4. Where are the control groups?
  5. Is the accuracy of ImPACT that sensitive (is there even one accurate enough to make this assessment)?
  6. What did each individual do for management of the concussion in the two days?
