FUNCAP-27 · Functional capacity 0–6
FUNCAP-27
Questionnaire.
Validated FUNCAP-27 questionnaire for functional capacity in ME/CFS. It scores eight everyday-function domains from 0 to 6 and reports the total as the mean of those domain scores.

FUNCAP-27 Questionnaire & Functional Capacity Score
1
What this questionnaire measures
FUNCAP-27 measures functional capacity across eight domains: personal hygiene/basic functions, walking, being upright, activities at home, communication, activities outside the home, reactions to light and sound, and concentration.
2
When this questionnaire is useful
It is useful when everyday functional capacity or change over time should be documented in a structured and repeatable way.
3
What the result does not do
FUNCAP-27 is not a diagnostic tool and its validated total score does not define universal mild, moderate, or severe ME/CFS cut-offs.
What does it check?
Domain A
Personal hygiene & basic functions
Everyday self-care and basic personal activities.
Domain B
Walking
Functional capacity for walking-related activities.
Domain C
Being upright
Capacity for activities that require sitting or standing upright.
Domain D
Activities at home
Capacity for household and other activities at home.
Domain E
Communication
Capacity for conversations and other communication demands.
Domain F
Activities outside the home
Capacity for errands, appointments, and activities away from home.
Domain G
Light & sound
Functional impact of light and sound exposure.
Domain H
Concentration
Capacity for sustained cognitive and concentration tasks.
When it helps, its limits & next steps
Important limits
not a diagnostic check for ME/CFS
not a replacement for medical functional assessment
not a recommendation to increase activity when PEM is present
After the result
connect the result with symptom course and exertion response
if PEM is present, interpret the score with recovery time and crash patterns
repeat the questionnaire when daily life or treatment changes
Common questions
Everything about the check
Before you start – the most important answers at a glance.
What does FUNCAP-27 measure?
FUNCAP-27 measures functional capacity across eight everyday-life domains on a 0–6 scale. Higher scores indicate greater functional capacity.
How is the FUNCAP-27 total score calculated?
Each of the eight domains receives a mean score. The published total score is the arithmetic mean of those eight domain scores; the domains are not given custom weights.
Does FUNCAP-27 define mild, moderate, and severe ME/CFS?
No universal cut-offs for mild, moderate, or severe ME/CFS are defined by the validated total score. FUNCAP-27 describes functional capacity and does not replace clinical severity assessment.
What do scores from 0 to 6 mean?
A score of 0 means the activity cannot be performed; 6 means it is unproblematic and does not affect other activities. Values in between represent graded functional capacity.
Can FUNCAP-27 diagnose ME/CFS?
No. FUNCAP-27 is a functional-capacity questionnaire, not a diagnostic test.
Why repeat FUNCAP-27?
Repeated measurements can document changes in functional capacity over time. Interpretation should still consider the broader clinical and PEM context.
