What is the Association with Several Physical, Mental, & Cognitive Health Outcomes with Gait Speed in Older Adults?

Research Paper Title

Clinical and Ambulatory Gait Speed in Older Adults: Associations With Several Physical, Mental, and Cognitive Health Outcomes.


Although clinical gait speed may indicate health and wellbeing in older adults, there is a lack of studies comparing clinical tests with ambulatory gait speed with regard to several health outcomes.

The objective of this study was to examine the associations of clinical gait speed, measured by the 2.44 meter walk test and the ambulatory gait speed with several physical, mental, and cognitive health outcomes in older adults.

A cross-sectional design was used.


The study population comprised 432 high-functioning community-dwelling older adults (287 women) aged between 65 and 92.

Clinical and ambulatory gait speeds were measured using the 2.44 m walk test and a portable gait analysis device, respectively.

Multiple linear regressions were used to examine the association of clinical and ambulatory gait speeds with several health outcomes (BMI, waist circumference, systolic and diastolic blood pressure, chronic conditions, self-rated health, exhaustion, upper and lower body strength, physical and mental health status, cognitive status and self-rated cognitive status).


The results showed that the average gait speed for clinical and ambulatory measures cannot be directly compared.

Clinical gait speed was associated with 7 health outcomes, while the ambulatory gait speed was associated with 6 health outcomes.

The significant associations between measures of gait speed and the health outcomes converged in 5 of the 13 health outcomes studied, however, the strength of associations were singly different between measures.

The short monitoring time, the inability to distinguish between the ambulatory gait speed inside the home and outdoor gait speed, and the under-representative sample are limitations of the study.


The results indicated differences in the number and strength of associations between clinical and ambulatory gait speed.

Both measures have construct validity because they have been associated with physical and health outcomes, however, they may have different predictive validity.

Further research should be done to compare their predictive validity in longitudinal designs.
