1. What is a Gait Speed Calculator?

Definition: This calculator measures walking speed by dividing distance walked by time taken.

Purpose: It helps healthcare professionals and researchers assess mobility, functional status, and fall risk in patients.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( GS \) — Gait speed (meters/second)
• \( D \) — Distance walked (meters)
• \( T \) — Time taken (seconds)

Explanation: The simple division of distance by time gives the average walking speed.

3. Importance of Gait Speed Measurement

Details: Gait speed is a vital sign of mobility and overall health. Slower speeds may indicate increased fall risk, functional decline, or underlying health issues.

4. Using the Calculator

Tips: Enter the distance walked in meters and time taken in seconds. Both values must be > 0. Typical walking tests use 4-10 meter distances.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal gait speed?
A: Healthy older adults typically walk 1.2-1.4 m/s. Speeds below 1.0 m/s may indicate mobility impairment.

Q2: How is the distance measured?
A: Measure the exact straight-line walking distance, typically using a marked walkway.

Q3: What timing method should I use?
A: Use a stopwatch to time from first movement to when the first foot completely crosses the finish line.

Q4: Why measure in meters/second?
A: m/s is the standard scientific unit for gait speed and allows comparison across studies.

Q5: Should patients use assistive devices?
A: Test with whatever devices they normally use, as this reflects their typical mobility.
