説明
This paper describes a novel method to measure spontaneous body sway in static upright stance by using a CCD video camera system. Three markers were put on subjects' back and legs, and three cameras were employed to record the motion of makers, respectively. Body sway in coronal direction is optimal for stability evaluation. During a period of 30 seconds of recording time, averaged angular velocity (TSSr) of the body sway is calculated, and was used as an index for the stability evaluation. To minimize ageing and physique influences on body sway, an empirical model was established to calculate the standard value (TSSeo) of body sway in different age, weight and height (all in eye-open). An investigation on a 51 elderly females group proved that the ratio of TSSeo/TSSr is quite correlated with falls happening frequency. Further more, a PID control model was as used for balance keeping study. The results suggest valuable of this model for stability evaluation.
