Outcome measures

Functional Ambulation Categories

Draft — clinical review required

A category scale of how much physical help or supervision a person needs to walk.

Assistance scaleSchematic setup — not to scale

Version shown: Category descriptions per published scale.

Lower scoreHigher scoreExaminer-rated ordinal scale — use the published form
Before / after comparison

Change: 0.00

Compare the change with measurement error and meaningful-change values for the same population and protocol, citing the source. Same protocol, aid and conditions on both occasions.

What it measures
  • Level of assistance needed for walking.
Populations and purposes
  • Stroke and other neurological populations; inpatient settings.
Equipment and space
  • Safe walking area.
Administration overview
  • Observe walking and assign the category that matches the support needed.
  • Use the full validated protocol (linked below) when testing patients.
Scoring and units
  • Six categories from 0 (cannot walk or needs help of two) to 5 (independent on all surfaces).
Meaning of a higher or lower score
  • Higher category = more independent walking.
Interpretation example
  • A person needing standby supervision but no physical help sits in a middle category.
Limitations
  • Coarse; does not measure speed or quality.
  • Norms, fall-risk thresholds, MDC and MCID differ by population and protocol; they are not universal. Measurement error is not the same as clinically meaningful change.

Draft — clinical review required

Starting points for verification. Validated protocols are linked where available; clinical content has not yet been reviewed.

Learning objectives
  • Explain what the Functional Ambulation Categories measures and for whom.
  • Describe the set-up and administration overview.
  • Interpret a result with its units, population and limitations.
