Gait Speed Formula:
| From: | To: |
Gait speed is a measure of walking speed, typically calculated as the time taken to walk a specific distance. It is a key indicator of mobility, functional status, and overall health in clinical and research settings.
The calculator uses the gait speed formula:
Where:
Explanation: The calculation divides the 4-meter distance by the time taken to complete the walk, providing gait speed in meters per second.
Details: Gait speed is a reliable predictor of functional decline, fall risk, hospitalization, and mortality. It serves as a simple yet powerful assessment tool in geriatric medicine, rehabilitation, and general health screening.
Tips: Enter the time taken to walk 4 meters in seconds. The time must be greater than 0. For accurate results, ensure the walking test is conducted on a straight, unobstructed path.
Q1: What is a normal gait speed for adults?
A: Normal gait speed varies by age, but generally 1.0-1.4 m/s is considered normal for healthy adults. Below 0.8 m/s may indicate mobility impairment.
Q2: Why use 4 meters for the test?
A: The 4-meter walk test is a standardized, practical distance that provides reliable results while being easy to administer in clinical settings.
Q3: How should the test be conducted?
A: The test should be performed on a straight, level surface. Participants walk at their usual pace from a standing start, and timing begins at the first foot movement.
Q4: What factors affect gait speed?
A: Age, gender, height, muscle strength, balance, neurological conditions, and overall health status can all influence gait speed.
Q5: Can this calculator be used for clinical diagnosis?
A: This calculator provides a quantitative measure, but clinical interpretation should be done by healthcare professionals in context with other assessments.
