Gait Speed Calculator
Calculate walking speed (gait speed) to evaluate physical function, frailty status, and fall risk in older adults.
Input Parameters
Enter details for calculation.
Gait Speed
Expert Tip
Gait speed < 0.8 m/s is a widely accepted clinical threshold for sarcopenia, frailty, and high risk of falls.
Calculation Methodology & Details
Formula
Calculates the walking speed over a short flat course (e.g. 4-meter gait speed test).

How Gait Speed is Evaluated
Follow these steps to use this calculator:
Mark Distance
Usually a 4-meter or 10-meter straight course.
Time the Walk
Measure walking time at a comfortable, normal pace.

ℹ️ About this Calculation
This orthopaedics and musculoskeletal clinical calculator evaluates joint replacement outcomes, osteoporotic fracture risk, spinal deformity severity, and physical mobility benchmarks based on AAOS clinical protocols.
Variable Glossary
Biomechanical Data
DXA T-score, Cobb angle degrees, gait velocity (m/s), dynamometer grip strength (kg), or functional survey items.
Functional Index
10-year major osteoporotic fracture probability (FRAX %), Oxford joint score (0-48), or spinal curvature classification.
How to Calculate Step-by-Step
Step 1
Input patient bone density BMD values, spinal radiograph degrees, or physical test performance numbers.
Step 2
Select patient age, gender, and secondary clinical risk factors (prior fracture history, steroid use).
Step 3
Review calculated joint function impairment tiers, sarcopenia risk categories, or fracture intervention thresholds.
