Background and Purpose: Vision has primary role in governing spatial orientation and balance. Monitoring body position to external world by vision enables an individual to detect and to react to very slight shifts in body position. The aim of the study was to find out effect of eye movements on dynamic equilibrium

Method: In Phase 1: Dynamic stability platform was innovated which is an unstable horizontal platform that is movable in frontal plane. In Phase 2: We placed a visual chart at a distance of 20 feet from the stability platform and then the effect of three different eye movements on dynamic equilibrium was analyzed. These three eye movements were Fixed Visual Fixation (FVF), Smooth Pursuit Eye Movement (SPEM) and Random Eye Movement.

Results: Inter-rater reliability of dynamic stability platform was found to be 0.822. Majority of the individuals were within the tilt angle ranges of 00-50 and 50-100 irrespective of the eye movement used. Very few individuals (n=3) were within the tilt angle ranges of 200-250 and 300-350. Among the eye movements, smooth pursuit eye movement showed more deviation compared to other movements.

Conclusion: Inter-rater reliability of dynamic stability platform was found to be good. We did not find any significant effect of eye movements on dynamic equilibrium.

Abstract


Background and Purpose: Vision has primary role in governing spatial orientation and balance. Monitoring body position to external world by vision enables an individual to detect and to react to very slight shifts in body position. The aim of the study was to find out effect of eye movements on dynamic equilibrium

Method: In Phase 1: Dynamic stability platform was innovated which is an unstable horizontal platform that is movable in frontal plane. In Phase 2: We placed a visual chart at a distance of 20 feet from the stability platform and then the effect of three different eye movements on dynamic equilibrium was analyzed. These three eye movements were Fixed Visual Fixation (FVF), Smooth Pursuit Eye Movement (SPEM) and Random Eye Movement.

Results: Inter-rater reliability of dynamic stability platform was found to be 0.822. Majority of the individuals were within the tilt angle ranges of 00-50 and 50-100 irrespective of the eye movement used. Very few individuals (n=3) were within the tilt angle ranges of 200-250 and 300-350. Among the eye movements, smooth pursuit eye movement showed more deviation compared to other movements.

Conclusion: Inter-rater reliability of dynamic stability platform was found to be good. We did not find any significant effect of eye movements on dynamic equilibrium.
