Gait Speed Measurement for Assessing Mobility

Gait speed was extracted from the SPPB testing. Gait speed was measured twice over a 4-meter distance, with the better of the two gait speeds used for analyses. Gait speed can usually be completed in two minutes with the use of a stopwatch and a four-meter tape. Test-retest reliability for gait speed in older adults is given by Pearson r=0.93 and ICC=0.78,26 (link) and among frail, older adults, ICC=0.79.27 (link) Gait speed alone has been reported to be nearly as good a predictor of ADL and mobility disability as the total SPPB summary score.9 (link)

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
