INTRODUCTION: Increased adiposity and cognitive impairments are both associated with gait changes in older adults; however, their combined impact on gait kinematics has not been specifically examined. The aim of this study was to investigate the combined contribution of adiposity and cognitive impairment to gait alterations in older adults.
METHODS: A total of 30 older adults with body mass index (BMI) values ranging from 18.5 kg/m2 (normal weight) to 40.0 kg/m2 (class 2 obesity) were recruited for this study. In session one, anthropometric data were collected. In session two, cognitive function was assessed using the Montreal Cognitive Assessment and a verbal N-back task. Gait kinematics were evaluated during over-ground walking.
RESULTS: Ankle kinematics were significantly affected by attention, abstraction, and adiposity measures. Hip kinematics were significantly associated with attention, whereas knee kinematics were primarily associated with working memory. No effects of adiposity were observed in hip or knee kinematics.
DISCUSSION: This study found that cognitive impairments were more consistently associated with gait kinematics in older adults. However, adiposity only was associated with ankle kinematics, suggesting that central adiposity may influence distal joint control. These findings underscore the regulatory role of executive function in gait and suggest that interventions targeting cognition may have a greater impact on mobility in aging populations than those focused solely on adiposity.
CONCLUSION: Cognitive impairments in key executive function domains (attention, abstraction, and working memory) have a stronger impact on gait in older adults than adiposity.
