Three-dimensional analysis of the difference in asymmetry between the feet of patients with cerebrovascular events and healthy individuals

Abstract

Objective: This study aimed to conduct a three-dimensional analysis of foot asymmetry in patients who have suffered cerebrovascular events (stroke) compared to healthy individuals. Methods: A total of fourteen patients experiencing right-sided paralysis and twenty healthy individuals participated in this study. All subjects enrolled in this study were scanned using a three-dimensional scanner to examine their feet. Scanning was conducted with the subject supinely, capturing slightly above the ankle level. The digital image of the left foot was mirrored and superimposed with the right foot to measure asymmetry. Asymmetry was quantified through the root mean square (RMS) difference values, with a higher RMS value indicating increased asymmetry. The study findings illustrate the occurrence of foot asymmetry. Results: The mean RMS values of healthy participants were markedly lower than those of participants with cardiovascular events (p<0.05). Additionally, upon comparing the asymmetry between the right and left feet of healthy participants with identical values in the cardiovascular event group, it was discovered that the right foot of the cardiovascular event group was significantly smaller than the left foot (p<0.05). Conclusion: Patients with cardiovascular events necessitate rehabilitation programs addressing balance and walking difficulties. Furthermore, certain patients with stroke may require orthotic devices. Our study’s results will aid in creating rehabilitation programs and orthotic device designs for stroke patients.
