1. What is a Gait Speed Calculator?

Definition: This calculator measures walking speed by dividing distance walked by time taken, expressed in meters per second (m/s).

Purpose: It helps physical therapists assess mobility, track rehabilitation progress, and identify fall risks 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 provides an objective measure of walking speed.

3. Importance of Gait Speed Measurement

Details: Gait speed is a vital sign of mobility that correlates with functional ability, fall risk, and overall health status.

4. Using the Calculator

Tips: Measure the exact distance walked (typically 4-10 meters) and the precise time taken. Both values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal gait speed?
A: Healthy older adults typically walk at 1.2-1.4 m/s. Speeds below 0.8 m/s indicate increased fall risk.

Q2: How is the distance measured?
A: Standard tests use 4-10 meter walkways, with timing starting after initial acceleration.

Q3: Why is gait speed important in therapy?
A: It's a reliable, objective measure of functional mobility and rehabilitation progress.

Q4: Should patients use assistive devices during testing?
A: Test conditions should match the patient's typical walking pattern, with or without devices.

Q5: How often should gait speed be measured?
A: Weekly or biweekly during rehabilitation to track progress and adjust treatment plans.
