Functional capacity assessment: what it is and when to order one
Objective testing for contested capacity questions — and how to brief it so the result means something.
A functional capacity assessment (also called a functional capacity evaluation or FCE) is a structured, objective assessment of what a person can physically and functionally do — lifting, carrying, postural tolerance, task-specific capability — usually performed by an occupational therapist or physiotherapist. On a claim, it turns a contested capacity question into tested evidence.
Key Takeaways
- What it measures: tested physical and functional capability against the demands of real or proposed duties
- Who performs it: occupational therapists and physiotherapists using standardised protocols
- When to order one: contested capacity, certificates repeating unchanged, capacity implausible against the medication load, or a RTW plan needing objective grounding
- Its limit: a snapshot under test conditions — it does not capture medication variability across a day or week
- Get more from it: brief the assessor with the reconciled medication history so tested function is interpreted against the pharmacological reality
What the assessment covers
Standard functional capacity protocols test:
- Material handling: lifting, carrying, pushing and pulling — floor-to-waist, waist-to-shoulder, sustained vs occasional
- Positional tolerance: sitting, standing, walking, kneeling, reaching — duration and frequency
- Task simulation: job-specific demands where the referral identifies them
- Consistency of effort: built-in validity checks on whether tested performance reflects true capability
The report maps results against the demands of identified duties — which means the referral matters: an FCE briefed with actual duty demands and the worker's clinical context returns a usable capability map; a generic referral returns generic numbers.
The medication blind spot — and how to close it
An FCE tests the worker as they present on the day. Medication state on the day is rarely recorded and never standardised: morning-dose sedation, end-of-dose withdrawal, and week-to-week regimen changes all move tested capability. On heavily medicated claims this is the difference between an FCE that resolves the capacity question and one that adds a third conflicting data point.
The fix is in the referral: attach the reconciled medication history (how reconciliation works), flag the sedating agents and their dosing times, and ask the assessor to record medications taken on the day of testing. Tested function interpreted against pharmacological reality is evidence; tested function alone is a snapshot.
