Introduction: The ability to control of body various positions in space is due to the complex interaction of nervous, sensory and musculoskeletal systems , which is generally defined as a postural control system. Researchers have defined postural control including body position control in space for two purposes: body stability and body orientation. Thus, the purpose of this study was to investigation the effect of visual system manipulation on postural control among elderly.
Methodology: This research is a semi-experimental study. 20 elderly people and 20 adults selected with available sampling method and participated in this research. To evaluate the postural control of subjects, the first (all sensory available) and second (visual sensory not-available) stages of sensory organization test (SOT) in computerized dynamic posturogeraphy system was used. Each stage was repeated three times, and each repetition was 20 seconds.
Results: Results of independent t test showed that there are significant differences in groups (P<0.05). Based on independent t test results in first and second stages of SOT test the postural control in adults were better than elderly people.
Discussion: Based on these results, reducing the sensory information (such as visual, proprioception, vestibular, and musculoskeletal) needed to control body posture occurs with aging, thus with improving visual system by using eye-wear or glasses and strengthening the muscular system in elderly people can improve postural control. Also, by improving postural control can be reduced falling in elderly people.
