1. What is Gait Speed?

Gait speed is a measure of how quickly an individual can walk a specified distance. It's a simple but powerful indicator of mobility, functional status, and overall health, particularly in older adults and rehabilitation settings.

2. How Does the Calculator Work?

The calculator uses the basic physics formula:

Where:

• \( Distance \) — The distance walked in meters
• \( Time \) — The time taken to cover the distance in seconds

Explanation: The formula calculates the average speed over the measured distance, providing a result in meters per second (m/s).

3. Importance of Gait Speed Measurement

Details: Gait speed is a vital sign in geriatric medicine and rehabilitation. It correlates with functional ability, fall risk, and overall mortality. Changes in gait speed can indicate improvement or decline in mobility status.

4. Using the Calculator

Tips: Enter the distance walked in meters and the time taken in seconds. Ensure both values are positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal gait speed for adults?
A: For healthy adults, normal comfortable gait speed typically ranges from 1.2 to 1.4 m/s. Speeds below 1.0 m/s may indicate mobility impairment.

Q2: How is gait speed measured clinically?
A: Typically measured over a set distance (often 4 or 10 meters) with timing starting after the first step and stopping before the last step to account for acceleration and deceleration.

Q3: Why is gait speed important in older adults?
A: Gait speed is a strong predictor of survival, hospitalizations, and functional decline in older populations. It's often called the "sixth vital sign" in geriatrics.

Q4: Can gait speed be improved?
A: Yes, through exercise interventions, strength training, balance exercises, and mobility practice, gait speed can often be improved.

Q5: What factors affect gait speed?
A: Age, muscle strength, balance, joint health, neurological conditions, pain, and overall fitness level all influence gait speed.
