1. What is Gait Speed?

Gait speed is a measure of how fast a person walks, typically expressed in meters per second (m/s). It's a simple but important clinical measure that reflects overall mobility function and health status.

2. How Does the Calculator Work?

The calculator uses the basic physics formula for speed:

Where:

• \( Speed \) — Gait speed in meters per second (m/s)
• \( Distance \) — Distance walked in meters
• \( Time \) — Time taken to walk the distance in seconds

Explanation: This formula calculates the average speed over the measured distance, providing a quantitative measure of walking ability.

3. Importance of Gait Speed Measurement

Details: Gait speed is a vital sign in geriatric and rehabilitation medicine. It correlates with functional status, predicts falls risk, and is associated with overall mortality. Regular monitoring can track rehabilitation progress and detect functional decline.

4. Using the Calculator

Tips: Measure the distance walked accurately in meters and the time taken in seconds. For clinical purposes, standard distances like 4 meters or 10 meters are commonly used. Ensure the person walks at their usual comfortable pace.

5. Frequently Asked Questions (FAQ)

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, while speeds below 0.6 m/s are associated with significant functional limitations.

Q2: How should gait speed be measured clinically?
A: Use a measured walkway (typically 4-10 meters), allow acceleration and deceleration space, and time only the middle section. The person should walk at their usual comfortable pace.

Q3: Does gait speed change with age?
A: Yes, gait speed typically decreases with age. A decline of more than 0.1 m/s per year may indicate underlying health issues that need investigation.

Q4: Can this calculator be used for running speed?
A: While the same formula applies, running speed calculations typically use shorter time intervals and may require more precise timing methods for accurate results.

Q5: What factors can affect gait speed?
A: Age, musculoskeletal conditions, neurological disorders, cardiovascular health, pain, fatigue, and environmental factors can all influence gait speed measurements.
