Summary
Novice users can reliably use the Sunnybrook Facial Grading System (SFGS) for assessing facial dysfunction. The SFGS demonstrates high intrarater and inter-rater reliability, comparable to expert performance.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Medical Imaging
Background:
- Facial dysfunction assessment requires reliable tools.
- The Sunnybrook Facial Grading System (SFGS) is a key instrument.
- Evaluating SFGS reliability with novice users is crucial for widespread clinical application.
Purpose of the Study:
- To determine the intrarater and inter-rater reliability of the Sunnybrook Facial Grading System (SFGS).
- To assess the performance of novice observers using the SFGS.
Main Methods:
- A prospective interval study was conducted at a tertiary teaching hospital.
- Eight novice observers independently rated 22 patients with facial dysfunction using the SFGS over two sittings.
- Intraclass correlation coefficients were calculated for component and total scores.
Main Results:
- Intrarater reliability coefficients ranged from .838 to .929, comparable to expert raters.
- Inter-rater reliability was high (.982 at time 1, .970 at time 2), exceeding previous expert rater findings.
- The SFGS demonstrated strong reliability among novice users.
Conclusions:
- The Sunnybrook Facial Grading System (SFGS) is a reliable tool for both novice and expert users.
- Novice users achieve reliability levels with the SFGS similar to those of expert users.
- This supports the broader adoption of the SFGS in clinical practice by a wider range of practitioners.
