Aims: Although body posture in relation to the dental condition has been of great interest in the dental profession, rumination bias has been a substantial obstacle to achieving a reliable objective evaluation of the intrinsic body posture. The aim of this study was to establish a posture control protocol that would minimize the effect of bias.
Methodology: Fifteen healthy male volunteers (23-33 years of age) participated in this study. The posture movement was recorded for 10 seconds by a three-dimensional motion capture system. The experiment was performed on four different days.
Results: The posture was most stable at 4-5 seconds after the start of the front bulb gaze (the mean coefficient of variation ranged from 0.1 to 44.1). The intraclass correlation coefficients for four days were 0.871-0.975 (P <= 0.001).
Conclusions: It was concluded that the use of this measurement method helped in producing a reliable intrinsic standing posture where unbiased evaluation of the effect of any intervention on the body posture is researched.
