Gait Speed Formula:
| From: | To: |
Gait speed calculation measures walking speed over a specified distance, typically 4 meters. It's a simple but powerful functional assessment tool used in physical therapy and geriatric care to evaluate mobility, functional status, and overall health.
The calculator uses the gait speed formula:
Where:
Explanation: The formula calculates walking speed by dividing the fixed distance of 4 meters by the time taken to complete the walk.
Details: Gait speed is a vital sign in rehabilitation and geriatric medicine. It correlates with functional independence, fall risk, hospital readmission rates, and overall mortality. Regular assessment helps track rehabilitation progress and functional decline.
Tips: Enter the time taken to walk 4 meters in seconds. The time must be greater than 0. For accurate results, use a stopwatch to measure the time precisely from start to finish of the 4-meter walk test.
Q1: What is a normal gait speed for older adults?
A: Normal gait speed for community-dwelling older adults is typically 1.0-1.3 m/s. Speeds below 0.8 m/s may indicate mobility impairment and increased fall risk.
Q2: How is the 4-meter walk test administered?
A: Mark a 4-meter course with additional 1-meter acceleration and deceleration zones. Time the middle 4 meters to eliminate acceleration/deceleration effects.
Q3: What factors can affect gait speed?
A: Age, muscle strength, balance, joint mobility, neurological conditions, pain, fatigue, and environmental factors can all influence gait speed measurements.
Q4: How often should gait speed be measured?
A: In rehabilitation settings, gait speed is typically measured at initial assessment, periodically during treatment, and at discharge to track progress.
Q5: Can this calculator be used for clinical decision making?
A: While this calculator provides accurate calculations, clinical decisions should be made by qualified healthcare professionals considering the full clinical context.
