RunTrak Trial Collection

Enter a unique Trial Name: we suggest to use the subject's ID, name, and date tested.

  • When the subject is ready, press the Record Button.
  • When the subject has completed the trial, press the Stop Button.

We recommend collecting several trials of the same type.

Once the trials are collected, go into Post Process mode and check that all markers are tracked and identified for the complete movement. You can optionally trim the trial (see Page 4-3 and 4-67 in the Cortex Reference Manual) as needed.
