Analysis of postural balancing movements in case of gait cycle in people with visual dysfunctions

Abstract

In the literature, it is often mentioned that uncorrected visual dysfunctions can influence the behaviour and motor activities of individuals, thus causing a limitation or diminution in the amplitude or frequency of their actions. The effects of visual dysfunctions of any kind may be amplified and can vary in time and in varying degrees both the posture, balance, stability and the type of gait of the patients. In this paper are presented the general aspects related to the identification of the parameters that affect the posture and the stability through the visual system dysfunctions and also the ways of compensating some of the causes that determine the postural imbalances. In the second part of the paper the experimental system and the recording methodology that emphasizes the effect of limitations in the functioning of the visual system, on the stability and the cycle of gait is presented. In this regard, a sample of 5 subjects with an average age of 25.1 years, with a visual emmetropic system, were induced a visual dysfunction related to the erroneous perception of the ambient colours and the postural equilibrium during gait cycle time. In the third part of the paper are presented the results and the conclusions obtained by applying the experimental methodology developed in this research.
