| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | VAS |
| Brief Description |
The Western Ontario Instability Index (WOSI) was specifically developed for use in shoulder instability and is a validated PRO measure. It is a valid, reliable, and responsive disease-specific quality of life measurement tool for patients with shoulder instability. The first domain, which is physical symptoms, contains 10 items. The remaining domains are sports, recreation, and work (4 items); lifestyle (4 items); and emotions (3 items) |
| Number of Items | 21 |
| Range | 0 - 2100 |
| Responses options/scale |
Yes 0-100 |
| Developed for | --- |
| PRACTICAL APPLICATION | |
| Method of administration | Physician |
| Recommendations to score |
Each item has a possible score from 0 to 100 (100-mm visual analog scale) and these scores are added to give a total score from 0 to 2100. |
| Score Interpretation | The best score possible is 0, which signifies that the patient has no decrease in shoulder-related quality of life. The worst score possible is 2100. This signifies that the patient has an extreme decrease in shoulder-related quality of life |
