Abstract
Objective: The purpose of this study was to investigate the effect of different age groups and gender on facial move-ments by using Moiré Topography.
Design: Observational study.
Setting: The Faculty of Physical Therapy, Cairo University.
Material and Methods: One hundred and fifty healthy subjects, both genders (75 males, 75 females), age range from 20-50 years. It was classified into three groups (20-30), (30- 40) and (40-50 years old) five facial angles were measured at both sides of the face for each subject three times during static position and during contraction ,this angles were raising, closing, smiling, kissing and blowing angles and the Auto-CAD program used to calculate and analyze this angles.
Results: There were a significant effect of age groups on the five facial movements including right and left raising, closing, smiling, kissing and blowing, as F=270, p=0.0001 also there was a significant effect of sex on the five facial an-gles as F=135, p=0.0001 and finally there was a significant interaction effect of age groups and sex difference on the same five facial movements by two way ANOVA as F=270, p=0.0001. The regression analysis indicated that the correla-tions between age groups and facial movement were moderate negative significant correlation for all the five angles at right and left side ranging from (r=–0.52 to –0.61) and also there was a moderate negative significant correlation between sex and five facial angles.
Conclusions: There were a significant effect of age and sex different on the facial movements including the five angles of the face at right and left side and that with increasing the age, the decreased angles of the female are more than the decreased angles of the male in the range of the five facial angles.
