| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
The SFI is a is a single page 25-item questionnaire that aims to assess the spine from cervical to lumbar as a single kinetic chain, in reference to the patient’s functional status ‘over the last few days’. The SFI was developed as part of suite of 3 PROMs that include the upper (ULFI) and lower limb functional index (LLFI) would cover the entire musculoskeletal system with a common singular scoring PROM. |
| Number of Items | 25 |
| Range | --- |
| Responses options/scale |
Yes ‘Partly’(1/2) or ‘No (0) |
| Developed for | --- |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
The scores from the 25 items are added, this score is then multiplied by four and subtracted from 100 to generate a 0-100% score. Up to two missing responses are permitted. |
| Score Interpretation | 0% = maximum limitation or functional loss and 100% = no disability, normal or pre-injury status |
| Cut-off points | --- |
| Cut-off points applied to | --- |
| Smallest detectable change if described | Minimal detectable change=6.5% or 1.6 SFI points |
| Smallest detectable change applied to | --- |
| Completion time by the patient | 2.5 (range 1.5min to 2min 40sec) minutes |
| Scoring time by the assessor | 0.5 minutes |
| Training to score | Not necessary |
| Strengths | Easy to use |
| Limitations | Lengthy |
