The new HED-CC provides for thorough assessment and documentation of postconcussion headache. Proactive, real-time measurement helps children remember the details of their headache pain and correlating events/circumstances. An appealing, age-appropriate measure increases the likelihood of children's symptom tracking and data accuracy. The HED-CC will improve clinicians' understanding of postconcussion headache and guide treatment. Additional testing with a larger sample is required to establish clinical application benefits and improve reliability/validity of the new measure.
