Gait Speed Formula:
| From: | To: |
Gait speed is a measure of walking speed calculated from the time taken to walk a specific distance, typically 4 meters. It is an important clinical indicator of mobility, functional status, and overall health in various populations.
The calculator uses the gait speed formula:
Where:
Explanation: This formula calculates walking speed by dividing the fixed distance of 4 meters by the time taken to walk that distance.
Details: Gait speed is a reliable predictor of functional decline, frailty, and mortality in older adults. It is widely used in geriatric assessment, rehabilitation settings, and clinical trials to monitor mobility changes over time.
Tips: Enter the time taken to complete a 4-meter walk 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 1.2-1.4 m/s is considered normal for healthy adults. Values below 1.0 m/s may indicate mobility impairment.
Q2: Why use a 4-meter walk test?
A: The 4-meter walk test is standardized, easy to administer, and requires minimal space, making it practical for clinical settings while providing reliable gait speed measurements.
Q3: How should the walking test be conducted?
A: Participants should walk at their usual pace on a straight, level surface. Timing typically starts when the first foot crosses the start line and ends when the first foot crosses the finish line.
Q4: What factors can affect gait speed?
A: Age, gender, height, muscle strength, balance, neurological conditions, joint problems, and overall health status can all influence gait speed measurements.
Q5: When is gait speed assessment particularly important?
A: Gait speed assessment is crucial in geriatric evaluations, pre-operative assessments, monitoring rehabilitation progress, and screening for sarcopenia or frailty syndrome.
