Botulinum Toxin A in the Treatment of Chronic Tension‐Type Headache With Cervical Myofascial Trigger Points: A Randomized, Double‐Blind, Placebo‐Controlled Pilot Study

Abstract

The evidence for BT-A in headache is mixed, and even more so in CTTH. However, the putative technique of injecting BT-A directly into the ubiquitous MTPs in CTTH is partially supported in this pilot study. Definitive trials with larger samples are needed to test this hypothesis further.
