An appraisal was made on a validity study by Vanti et al, regarding the upper limb neurodynamic test 1 (ULTT1) for diagnosing carpal tunnel syndrome (CTS). The selected paper included current patients at an occupational medicine clinic with suspected CTS and referral for nerve conduction study (NCS).
Using Wainner’s Criteria to indicate a positive ULTT1, calculated sensitivity was 0.9167 and specificity was 0.150. In limiting criteria for a positive test by requiring provocation of 1st-3rd digits only, the sensitivity decreased to 0.5417, however specificity increased to 0.70.
This study was effective in defining the inclusion criteria for denoting a positive versus negative score when using the ULTT1.
