Gait Velocity is a marker of functional and cognitive status in older adults.  Slow gait speed has been associated with poor clinical outcomes such as cognitive decline, falls and hospitalization. This toolkit provides  instructions on how to perform a gait speed or gait velocity assessment.  It includes START and STOP labels, labels for the Timed Zone, and instructions on how to interprete and apply the results.  The examiner will need to measure and mark a walkway, and supply a stopwatch or watch with a second hand. By following these simple steps, gait velocity assessment can become a routine practice for clinicians who care for older adults.
