Decline in Gait Performance Detected by an Electronic Walkway System in 907 Older Adults of the Population-Based KORA-Age Study.
In: Gerontology, No. 2: pp. 165-173
Background: Gait changes at older ages are a strong predictor of adecline in lower extremity functions. However, large population-basedstudies assessing gait parameters in various gait tasks are lacking.Objective: We investigated the relationship of age, the use of mobilityaids and being fitted with an endoprosthesis with selected gaitparameters, assessed in different walking tasks. Methods: In thepopulation-based KORA-Age study, data from 907 men and women aged 65-91years were obtained using the validated electronic walkway systemGAITRite, which quantifies spatiotemporal gait parameters in themeasurement range of a 488 x 61 cm walkway mat. Participants completedthree walking tasks at different speeds (normal, slow and fast) and afourth walking task at normal speed with the additional task of countingbackwards (dual-task walking). Additionally, the impact ofendoprostheses (hip or knee) and mobility aids was assessed.
