Pain localization and response to botulinum toxin in cervical dystonia.

ABSTRACT:

Introduction

Pain is a common symptom of cervical dystonia (CD). The mainstay of treatment of CD is botulinum toxin, which is known to have benefits in relieving pain. We aimed to characterize the locations of pain in patients with CD, and to assess what factors may predict pain reduction following botulinum toxin injection.

Methods

We conducted a single-center observational study of CD patients who reported pain and who received botulinum toxin treatment. On the day of their toxin injection (in the untreated state), they filled out a survey evaluating primary and secondary sites of pain as indicated on a diagram, as well as Pain Numeric Rating Scale assessing average pain over the past 24 h. Two weeks later, they filled out a follow-up survey (in the treated state) to evalu
