| Popis: | A shift from subjective scales to objective measures of facial paralysis requires physical models against which to validate and calibrate the new objective techniques. The purpose of this report was to demonstrate such a model and to test the capacity of an objective computer system to accurately measure physical change. The physical model consisted of an advancing edge of a spreading gelatin film. The model was measured in submillimeter increments. Concurrent measurements were made using the computed system. Ten trials were conducted. The objective system proved to be exquisitely sensitive (0.03 mm) and highly correlated with the physical criterion model (Pearson's product moment correlation coefficient [r]=0.9849). Sensitive and calibrated objective methods of analysis of facial motion are crucial to the design of clinical trials, clinical studies of nerve regeneration, and comparisons of reanimation techniques. |
