Gait Speed Formula:
| From: | To: |
Gait speed is a measure of walking velocity calculated as distance divided by time. It is a key functional assessment tool in physical therapy used to evaluate mobility, functional status, and overall health in various patient populations.
The calculator uses the gait speed formula:
Where:
Explanation: This simple calculation provides valuable information about a person's walking ability and functional mobility.
Details: Gait speed is considered the "sixth vital sign" in rehabilitation. It correlates with functional independence, fall risk, hospital readmission rates, and overall mortality. Regular assessment helps track rehabilitation progress and treatment effectiveness.
Tips: Enter distance in meters and time in seconds. Ensure measurements are accurate for reliable results. Common test distances include 4 meters, 10 meters, or 6-minute walk test distances.
Q1: What is a normal gait speed for adults?
A: Normal comfortable gait speed for healthy adults is typically 1.2-1.4 m/s. Speeds below 1.0 m/s may indicate mobility impairment.
Q2: Why is gait speed important in physical therapy?
A: It provides objective data on functional mobility, helps set treatment goals, monitors progress, and predicts functional outcomes.
Q3: What distance should be used for gait speed testing?
A: Common standardized distances include 4m, 10m, or 6-minute walk test. The distance should be consistent for comparison over time.
Q4: How does age affect gait speed?
A: Gait speed typically decreases with age. Expected values decline approximately 1-2% per year after age 60.
Q5: When should gait speed be reassessed?
A: Regular reassessment every 2-4 weeks during active rehabilitation, or as clinically indicated based on patient progress and condition changes.
