Correlation of Foot Posture, Dynamic Balance and Gait Speed in Community-dwelling Older Individuals

Abstract

Introduction: Foot posture is crucial in maintaining stability and balance during movement. It encompasses the position and alignment of the feet and ankles, significantly impacting overall body stability and reducing the risk of falls. Dynamic balance refers to maintaining balance while in motion, encompassing walking, running, and jumping. Aim: To find a correlation between foot posture, dynamic balance and gait speed in community-dwelling older individuals. Materials and Methods: The correlational study included 100 community-dwelling older individuals who met the specified inclusion and exclusion criteria. The Foot Posture Index was utilised as the outcome measure for foot posture, the Modified Four-Square Step Test (MFSST) for dynamic balance, and the Gait Speed Test for gait speed assessment. Results: The results revealed a weak positive correlation between gait speed and foot posture, with a statistically significant weak positive correlation observed in individuals with normal foot posture. In contrast, a statistically significant moderate positive correlation was found between gait speed, dynamic balance, and pronated foot posture (r= 0.63, P < 0.05). Furthermore, a weak negative correlation was observed between gait speed and supinated foot posture, with a statistically significant moderate negative correlation between dynamic balance and supinated foot posture. Conclusion: Pronated foot posture demonstrated a stronger association with gait speed and dynamic balance than supinated and normal foot posture. These findings suggest that older adults with pronated foot posture experience greater effects on gait speed and dynamic balance. Keywords: Foot posture, Gait, Balance, Elderly
