Body Balance Analysis in the Visually Impaired Individuals Aged 18–24 Years

Abstract

Background: Proper body balance is maintained by both sensory, i.e., vision, hearing, vestibular, and proprioception, and motor nervous systems. Visual control facilitates balance both in a static position, as well as during movement. Visual dysfunctions can adversely affect balance and stability control. Methods: The study comprised a group of 30 individuals visually impaired from birth aged 18–24 years. The control group consisted of 50 persons in the same age range as the study group. The trial was performed as four separate tests: two on a stable surface platform, and two on an unstable surface platform. Results: No statistically significant differences were found in the posturography test on the stable platform between the study groups. When tested on an unstable ground surface, the visually impaired subjects obtained showed worse performance than the sighted persons. Statistically significant differences were observed in the majority of the analyzed results. Conclusions: Visually impaired individuals present a poorer ability to maintain balance under dynamic conditions. Tests conducted on the unstable surface platform seem to be more relevant and applicable in the diagnosis of the subjects with visual impairment, as they differentiate the subjects to a greater extent.

Impacts of visual impairment on pragmatic impairment: A systematic review and meta-analysis

“…First of all, we conducted quality risk assessment on the included articles [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46] by Review Manager 5.4 software to avoid the impact of high-risk dimensions on the study results [47].…”

Physical activity and sport practice to improve balance control of visually impaired individuals: a narrative review with future perspectives

“…Postural stability is referred to the body skill of maintaining balance and it is often assessed through postural sway analysis and quantification ( 86 , 87 ). According to research findings, visual disability-affected individuals generally show increased postural sways hence experiencing higher fear of falling ( 88 , 89 ).…”

The Barrier to Accessing Dental Healthcare Services Among the Institutionalized Visually Impaired Adults: A Qualitative Study

“…It is a visual issue that can cause reduced eyesight or even total blindness [ 2 ]. Almost 2.2 billion people worldwide suffer from some form of visual impairment; of those, at least 1 billion have an illness that could have been avoided or is still untreated [ 3 ]. The most important factors contributing to vision impairment and blindness are cataracts and uncorrected refractive errors.…”
