functional mobility scale
A 6-point ordinal scale rating a child's or adult's mode of mobility over specific walking distances, commonly used to track ambulation status during rehabilitation.
Full Definition
The Functional Mobility Scale (FMS) classifies mobility across three distances—5 metres (home), 50 metres (school/work), and 500 metres (community)—using a 6-point rating from 1 (uses wheelchair) to 6 (independent on all surfaces). Although originally validated in pediatric populations with cerebral palsy, the FMS is increasingly applied in adult neurorehabilitation and geriatric rehabilitation to document functional ambulation status and goal trajectories. Editors should note that the FMS is recorded as three separate scores corresponding to the three distances (e.g., FMS: 4, 5, 6) and that collapsing these into a single score misrepresents the tool. 'Functional Mobility Scale' should be capitalised and expanded as FMS after first reference; it must not be conflated with generic phrases such as 'functional mobility assessment'.
Usage
Usage note: Always record all three distance scores separately. Capitalise as a proper instrument name. Do not conflate with the Functional Ambulation Category (FAC), which is a different tool using a different scale.
In Context
- "The physiotherapist documented Functional Mobility Scale (FMS) scores of 3, 4, and 5 at admission, indicating the patient required a walking frame at home and in the community." — Physiotherapy inpatient assessment
- "At discharge, the patient's FMS had improved to 5, 5, 6, reflecting her ability to walk independently in the community without a mobility aid." — Geriatric rehabilitation discharge summary
