SF-36 Physical Function Domain Calculator (Cardiac Rehab)
Physical functioning assessment
Select one response for each activity.
Scoring and clinical context
The Physical Functioning (PF) domain contains 10 activities spanning vigorous activity, mobility, stair climbing, bending, and self-care. Each response is recoded to a 0–100 scale, with higher values representing fewer limitations. The domain score is the mean of the ten recoded item scores.
Item recoding used here
| Response | Recoded score |
|---|---|
| Limited a lot | 0 |
| Limited a little | 50 |
| Not limited at all | 100 |
Important limitations
- This calculator uses the three response levels for the PF items and the simple 0–100 item-mean approach described in RAND-36 scoring instructions. Confirm the exact survey version and its authorized scoring manual before use in formal research or clinical reporting.
- The descriptive bands displayed with the result are explanatory text only, not validated SF-36 thresholds. No mortality prediction or treatment recommendation is generated.
- SF-36/SF-36v2 wording, administration, scoring, and licensing conditions may differ. This page is a scoring aid, not a substitute for the validated questionnaire or its manual.
