Introduction
also see gait evaluation
Clinical significance
- normal gait speed is > ~0.9 meters/second (see gait evaluation)
- gait speed < 0.56 meters/second is associated with increased risk of falls[3]
- gait speed is a predictor of survival in the elderly[1]
- also predicts disability, long-term nursing home placement
- better predictor than grip strength
- characteristic of prefrailty
- gait speed better predictor of frailty than step length or chair rise time[7]
- slower gait speed at age 45 is associated with:[3]
- self-reported physical limitations
- faster aging, assessed by biomarkers (BMI & cardiorespiratory fitness)
- accelerated facial aging (assessment of facial photographs)
- smaller total brain volume, thinner meaner cortex, smaller total brain surface area[3]
- orthostatic hypotension[5]
Management
- individualized, supervised, exercise program
