Effect of Dominant Versus Non-dominant Vision in Postural Control
OBJECTIVE: To assess the effect of dominant and non-dominant vision in controlling posture in quiet stance. METHOD: Twenty-five healthy elderly subjects aged over 60 years old and twenty-five young subjects aged under 30 years old were assessed by computerized dynamic posturography. Postural stabili...

description | OBJECTIVE: To assess the effect of dominant and non-dominant vision in controlling posture in quiet stance. METHOD: Twenty-five healthy elderly subjects aged over 60 years old and twenty-five young subjects aged under 30 years old were assessed by computerized dynamic posturography. Postural stability was measured in two conditions; dominant eye open and non-dominant eye open. We used the sensory organization test (SOT) for evaluating sensory impairment. A SOT assessed the subject's ability to use and integrate somatosensory input, vision, and vestibular cues effectively to maintain balance. The SOT was conducted 3 times, and the average value of the 3 trials was used for data analysis. Equilibrium scores reflected the subject's anteroposterior sway. The highest possible score was 100, which indicated that the subject did not sway at all, and a score of 0 indicated a fall from the footplate. Determination of ocular dominance was performed by a hole-in-the card test. RESULTS: For the twenty-five young subjects in this study, equilibrium score in two conditions did not differ. However, for elderly subjects over 60 years, the equilibrium score in dominant vision was higher than in nondominant vision (p<0.05). CONCLUSION: In young subjects, there were no significant differences in postural control between dominant vision and non-dominant vision. However, in elderly subjects, postural control in non-dominant vision was significantly impaired. Therefore, the evaluation of a dominant eye should be considered in rehabilitation programs for elderly people. |
