Changes of Gait Patterns after Correction of Refractive Error in the Elderly with Cataracts

초록

The aim of this study was to verify whether providing older adults with actual corrected glasses for refractive errors would have a positive impact on their gait patterns. This study included 30 subjects with an average age of 78.77 +/- 7.27 years. The measurement of gait patterns was performed using the Optogait analysis system, and a comparative analysis was performed to compare the patients before and after they wore correction glasses. Step length, stride length, and width showed significant increases after the patients wore correction glasses, and cadence showed a decrease compared to before they wore correction glasses (p < 0.05). A strong positive correlation was observed between step length and stride length (r = 0.779, p < 0.001), and a decrease in cadence (r = 0.686, p < 0.001) was observed with increasing step length. In addition, a proportional increase in speed with increasing step length was observed after the patients wore correction glasses (r = 0.416, p < 0.05). The correction of residual refractive errors in order to provide optimal visual information can have a positive effect on gait patterns. Therefore, efforts by optometry professionals to provide the accurate correction of refractive errors in elderly patients can contribute to the prevention of falls, and collaboration with other experts is needed.
