| Brief Description |
patients diagnosed as having CTS by either the questionnaire, nerve conduction testing, or both, underwent decompression surgery. Symptom improvement was considered as the "gold standard" for true CTS. The results revealed a sensitivity of 85% for the scored questionnaire and 92% for nerve conduction testing with a positive predictive value of 90% for the scored questionnaire and 92% for neurophysiological assessment. Therefore, it was concluded that a scored questionnaire can replace nerve conduction studies in the initial assessment of whether patients presenting with dysesthesia in the fingers should undergo surgery. |
| C. Criterion validity | Not Tested |
| Comparison with a 'gold standard' Continuous scores: correlations, ROC curves Dichotomus: Sensitivity & Specificity (Describe) |
