What is normal adult gait velocity?

Normal comfortable walking speed: 1.2–1.4 m/s (adults). <0.8 m/s = community ambulatory only; <0.6 m/s = household ambulation; <0.4 m/s = limited community access.

How is gait velocity calculated?

Velocity (m/s) = distance (m) ÷ time (s). For 10-Meter Walk Test: divide 10 m by seconds taken to walk the middle 6 m (not including acceleration/deceleration zones).

How to use this calculator

1
Enter patient clinical data
Enter the patient's age, weight, lab values, vitals, or clinical findings into the Gait Analysis Calculator — Velocity, Cadence, Stride Length input fields.
2
Select the clinical scoring system
Select or confirm the appropriate clinical scoring system or reference range for the patient population.
3
Calculate the clinical score
Press Calculate to compute the clinical score, risk estimate, or diagnostic result.
4
Interpret the result
Review the output against the provided reference ranges, risk categories, or guideline thresholds. Consult a qualified clinician before acting on results.

Formula

Result = f(patient inputs, clinical reference)

patient inputs: Age, weight, height, lab values, vitals, or clinical findings entered into the Gait Analysis.
clinical reference: Reference range, scoring system, or population standard the result is compared against.
Result: Computed clinical score, risk estimate, or diagnostic value.

Clinical results are decision-support only and must be interpreted by a qualified clinician.

Glossary and Definitions

Clinical score: A numeric value derived from patient inputs that estimates risk, severity, or diagnostic likelihood for a given condition.
Reference range: The set of values considered normal for a healthy population, used to interpret a calculated result.
Sensitivity: The probability that a positive result correctly identifies a patient with the condition.
Specificity: The probability that a negative result correctly identifies a patient without the condition.
