U.S., Nov. 13 -- ClinicalTrials.gov registry received information related to the study (NCT07931157) titled 'Electromyography-Guidance for Chemodenervation in Facial Synkinesis' on Nov. 01.
Brief Summary: Injection of botulinum toxin (BT) is standard of care at Vanderbilt University Medical Center (VUMC) for management of facial synkinesis. Current practices at VUMC involve use of electromyography (EMG) guidance for precise targeting of selective muscles, but the utility of this practice has never been objectively measured. Patients underwent standardized BT injection with use of EMG guidance as well as a BT injection without use of EMG-guidance, separated by 3 months. Patients were allocated such that half underwent EMG-guidance during th...
