THE IMPACT OF VISUAL ACUITY ON POSTURAL BALANCE: A CROSS-SECTIONAL ANALYSIS
Keywords:
Visual acuity, balance, proprioception, vestibule, equilibrium, perceptionAbstract
Background of the study: Vision plays a significant role in keeping a body's balance steady by consistently giving information about the environment, body movement and body position to the higher centers. Disruption can cause problems with Balance.
Methodology: It was a cross-sectional study based on the convenience sampling method. 384 participants were recruited. Data was gathered from five different settings. All balance components were screened using various tests, i.e., Romberg's and a modified tandem walk, to screen for proprioception and vestibular abnormalities.
Results: Of 384 participants, 66.9% in Group A had normal vision (6/6 – 6/9), and 33.1% in Group 2 had slightly impaired vision (6/12 – 6/18). The frequency table of BBS shows that 356(92.7%) participants had average Balance, and 28(7.3%) participants had impaired balance. Cross-tabulation of the Snellen group with BBS shows that 257 participants of Group 1 had normal vision and Balance, and no one had impaired Balance. One hundred twenty-seven participants of Group 2 had slightly impaired vision; among them, 99 participants had average Balance, and 28 participants had impaired Balance with a p-value of 0.000 found to be significant.
Conclusion: This study concludes Participants with visual impairments had the most negligible impact on the balance system, whereas those with normal vision exhibited no impact.
