Abstract Clinicians typically evaluate head posture and cervical range of motion in both standing and sitting positions. There are currently few quantitative data available regarding resting head posture (RHP) or total head excursion (THE), a retraction-protraction gliding range of head motion in the sagittal plane, and where the RHP lies within THE. The purposes of this study were to describe quick and simple methods to determine quantitative measurements of THE, RHP while sitting, and RHP while standing, to provide preliminary data on these postural measurements for men and women in four age categories; and to determine the effects of gender and age on these measurements. Subjects included 218 able-bodied adults. Measurements of THE, RHP while sitting, and RHP while standing were taken. A two-way multivariate analysis of variance followed by two-way analyses of variance showed only the main effect of gender to be significant (p less than .05) for each of the dependent measurements. Across the age groups, men had a greater excursion distance from retraction to protraction than women. Within THE, women held their heads more forward than men. Men held their heads farther from the vertical than women while standing. These results indicate that normal head and neck posture is different for men and women and should not be judged by the same standard. The methods used in this study are clinically advantageous in that they produce objective, quantitative measurements of THE and RHP that may be obtained quickly and with minimal equipment.
