The Relationship between Headache Severity and Convergence Insufficiency in a Post-Concussive Population

Abstract

Conclusions The results ofthis study suggest that headache and NPC measurements following concussion are very weakly associated. Given the episodic nature of headaches, it may be that statistically significant correlations are not evident unless there is a certain headache severity at time ofNPC measurement. Future studies are needed in order to determine whether and to what extent injury severity or patient demographic characteristics mediate this relationship.
