| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
The SFS measures disability caused by skin tightness in the upper limb and proximal muscle weakness. |
| Number of Items | 11 (9 items on upper limb function and 2 items on muscle weakness) |
| Range | 0-33 |
| Responses options/scale |
Yes Each item is scored under four categories ranging from 0 (able to perform in a normal manner) to 3 (impossible to achieve) |
| Developed for | Not specified |
| PRACTICAL APPLICATION | |
| Method of administration | Interviewer/assessor, Self-administered |
| Recommendations to score |
The total score is the sum of each item score. |
| Score Interpretation | Higher scores reflect higher functional impairment. |
| Cut-off points | --- |

| Smallest detectable change if described | --- |
| Smallest detectable change applied to | Not specified |
| Completion time by the patient | 0 minutes |
| Scoring time by the assessor | 0 minutes |
| Training to score | Not necessary |
| Strengths | Easy to use |
| Limitations | --- |
