Test-Retest Reliability and Agreement Between In-Person and Video Assessment of Facial Mimetic Function Using the eFACE Facial Grading System

What Is This Study About?

This study validated the reliability of the eFACE facial grading system by testing whether clinicians produce consistent scores across different times and assessment methods. The results confirmed eFACE as a reliable outcome measure.

Key Findings

• eFACE demonstrates strong test-retest reliability for facial palsy assessment
• In-person and video-based assessments produce consistent scores
• Validates eFACE as a reliable tool for tracking treatment outcomes over time

What This Means for Patients

Reliable outcome measures mean patients’ progress can be accurately tracked over time, and treatment outcomes can be meaningfully compared across different clinics and surgeons.
