Formula
Gait Speed = Distance ÷ Time (Distance in meters, Time in seconds)
Interpretation
- < 0.8 m/s – Potential mobility risk
- 0.8–1.0 m/s – Community ambulator
- > 1.0 m/s – Healthy gait speed
Assess mobility by calculating walking speed and comparing to average norms
Gait Speed = Distance ÷ Time (Distance in meters, Time in seconds)
Gait speed is the rate at which a person walks, typically measured in meters per second (m/s). It reflects overall mobility and is a key predictor of health outcomes in older adults.
It’s calculated using the formula: Gait Speed = Distance ÷ Time. You walk a set distance (e.g., 10 meters) and divide by the time it takes to cover that distance.
Slow gait speed (typically < 0.8 m/s) may indicate mobility limitations, increased fall risk, or underlying health issues, especially in elderly populations.
It's ideal for physical therapists, geriatric care providers, rehabilitation specialists, and individuals monitoring mobility at home.
Generally, 1.0 to 1.4 m/s is considered normal for healthy adults. Speeds above 1.0 m/s are associated with better survival and functional independence.
Pupil size 2–4 mm in bright light and 4–8 mm in the dark is normal.
