| Brief Description |
he scale showed strong correlation when compared to the results of other validated measurements including: (1) the Boston Carpal Tunnel Questionnaire, (2) the clinical assessment, (3) the neurophysiological study (NCS), and (4) ultrasound (US) evaluation for both carpal tunnel and tendonitis. Cross cultural assessment/ translated into Arabic |
| C. Criterion validity | Tested |
| Comparison with a 'gold standard' Continuous scores: correlations, ROC curves Dichotomus: Sensitivity & Specificity (Describe) |
There was a statistically significant difference between the CTS-PROMs scores before and after carpal tunnel injection. |
