Diagnostic utility of ultrasonography versus nerve conduction studies in mild carpal tunnel syndrome
Abstract Objective To prospectively compare high‐resolution ultrasonography (US) and nerve conduction velocity (NCV) in clinically diagnosed mild carpal tunnel syndrome (CTS). Methods Eighty‐five patients (70 women and 15 men, mean age 46.8 years) reported symptoms compatible with classic/probable C...

Methods Eighty‐five patients (70 women and 15 men, mean age 46.8 years) reported symptoms compatible with classic/probable CTS. The protocol included NCV of the median and ulnar nerves (distal motor latency [DML], sensory conduction velocity [SCV] from the third [M3 SCV] and fourth fingers [M4 SCV] to the wrist for the median nerve); electrophysiologic severity scale; self‐administered Levine/Boston questionnaire (BQ); and cross‐sectional area (CSA) measurement of the nerve at the tunnel inlet (CSA‐I), at the middle (CSA‐M), and at the outlet (CSA‐O). Relationship between age, body mass index, duration of symptoms, CSAs, NCV, electrophysiologic severity scale, and BQ scores was calculated.

Relationships were found between CSA‐I and M3 SCV (r = −0.45), M4 SCV (r = −0.56), and median nerve DML (r = 0.29).

The sensitivity increased to 76.5% if US and NCV were considered together. The highest concordance to detect absence/presence of abnormalities was between CSA‐I and NCV (77.6%; κ = 0.52).
