Gait velocity as a single predictor of adverse events in healthy seniors aged 75 years and older
Abstract
PURPOSE: Although gait velocity (GV) measurement could predict poor outcomes, few studies regarding its usefulness as a single test in well functioning elderly persons have been pursued. The aim of this study was to asses whether GV could be sufficient to predict adverse events such as hospitalization for any cause, requirement for a caregiver, nursing home placement, falls, fractures, or death in healthy elderly persons. METHODS: Ours was a cohort study comprising 102 well functioning participants aged 75 and older. Demographic features, health status, and functional capacity were assessed at baseline and followed for adverse outcomes. Measurements included evaluation of cognition, activities of daily living, and mobility. The time required to walk the middle 8 meters of 10 meters was defined as GV. Three GV groups were distinguished: high GV (>1.1 m/s), median GV (1-0.7 m/s), and low GV (<0.7 m/s). RESULTS: At baseline, the three groups were comparable in their health status with an average age of 79.6 +/- 4 years. At 24 months, the low GV group had a significantly higher incidence of adverse events than did the other groups. Low GV was a predictor of hospitalization (relative risk [RR] = 5.9, 95% confidence interval [CI], 1.9-8.5), requirement of a caregiver (RR = 9.5, 95% CI, 1.3-2.5), and new falls (RR = 5.4, 95% CI, 2.0-4.3). These associations remained significant after a multiple logistic regression analysis. CONCLUSIONS: GV measurement in the ambulatory setting may allow the detection of healthy elderly people at risk for adverse events. These data may suggest that simple assessment of GV is enough to predict adverse events in well functioning older persons.

Other cohorts with similar follow-ups and populations have shown results in line with the EPIDOS cohort.
“Other cohorts with similar follow-ups and population have shown results in the line with the EPIDOS cohort ( 43., 44., 45.).”
In the EFA study, gait speed was an independent predictor of falls with a relative risk of 5.4 (2-14.3).
“Gait speed was an independent predictor of falls with a RR of 5.4 (2-14.3)”
In the Estudio de Evaluación Funcional del Anciano (EFA) study (N=102, community dwelling, well functioning, 2-year follow-up, 10-meter walk), gait speed was an independent predictor of hospitalisation with a relative risk of 5.9 (1.9-18.5) for the lowest versus highest group (<0.7 m/s versus 1.1 m/s).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
