Evidence[edit | edit source]
Research was done on 2016 to find more suitable diagnostic test for carpal tunnel syndrome among carpal compression test (CCST, Tinel’s test (TT) and Phalen’s test (PT) test. Study shows sensitivity and specificity of Carpal compression test were higher than the both Tinel's and Phalen's test.also study suggest both CCT and TT were positive, the diagnosis is more likely to be CTS[2].
| [2] | Carpal compression test | Tinel's test | Phalen's test |
|---|---|---|---|
| sensitivity | 80.6% | 65.3% | 59.7% |
| specificity | 52.9% | 47.1% | 35.3% |
