1. What is Preferred Gait Velocity?

Definition: Preferred gait velocity (PGV) is the natural walking speed a person chooses when asked to walk at a comfortable pace.

Purpose: It's a key measure in rehabilitation, geriatrics, and sports medicine to assess mobility and functional status.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( PGV \) — Preferred gait velocity (meters/second)
• \( D \) — Distance walked (meters)
• \( T \) — Time taken (seconds)

Explanation: The distance covered is divided by the time taken to complete that distance.

3. Importance of Gait Velocity Measurement

Details: Gait speed is a powerful predictor of health outcomes, functional status, and survival in older adults.

4. Using the Calculator

Tips: Enter the distance walked in meters and the time taken in seconds. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal gait velocity for adults?
A: Healthy adults typically walk at 1.2-1.4 m/s. Below 1.0 m/s may indicate mobility impairment.

Q2: How is the distance typically measured?
A: Standard tests use 4-10 meter walkways, with timing of the middle section to avoid acceleration/deceleration.

Q3: Why measure in m/s?
A: Meters per second is the standard unit in clinical research and allows comparison across studies.

Q4: How does age affect gait velocity?
A: Velocity typically declines about 1-2% per year after age 60.

Q5: When should I be concerned about gait speed?
A: Speeds below 0.6 m/s indicate high risk for adverse outcomes; below 0.8 m/s suggests need for further assessment.
