Abstract
Background: The aim of this study was to investigate the effect of a botulinum toxin type A (BTX-A) injection in the masseter muscle using electromyography (EMG) in an animal model.
Methods: Ten male adult (>3 months of age) New Zealand white rabbits were used. Muscle activity was continuously recorded from 8 hours before to 8 hours after BTX-A injection. The rabbits received unilateral BTX-A injections of either 5 units (group 1, n?=?5) or 20 units (group 2, n?=?5).
Results: The masseter muscle activity of the rabbits was significantly reduced immediately after BTX-A injection (P?
Conclusion: Masseter muscle activity measured by EMG was immediately decreased after a BTX-A injection.
