| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Scale |
| Brief Description |
Lower-extremity self-administered activity scale validated for the assessment of patients' actual activity levels. The scores were spread over the range of the eighteen possible activity levels (range, 2 to 16 for the baseline scores and 3 to 17 for the six-month scores) |
| Number of Items | 18 |
| Range | 1-18 |
| Responses options/scale |
No |
| Developed for | Both |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
Patients have to choose among 18 options the one that describe best their regular daily activity, |
| Score Interpretation | Lower scores indicate worse physical activity |
| Cut-off points | --- |
| Cut-off points applied to | Both |
| Smallest detectable change if described | --- |
| Smallest detectable change applied to | --- |
| Completion time by the patient | - minutes |
| Scoring time by the assessor | - minutes |
| Training to score | Not necessary |
| Strengths | Easy to use, Useful in clinical practice & research |
| Limitations | --- |
