This prospective study was done to assess a technique of comparing Median-Ulnar sensory latency differences across the wrist (Sensory Palm [M-U]) to diagnose carpal tunnel syndrome (CTS) and to compare the relative sensitivities of other previously reported techniques: Median-Radial sensory difference (Sensory Thumb [M-R]), Median-Ulnar mixed palm difference (Mix Palm [M-U]) and Median-Ulnar sensory digit difference (Sensory Digits [M-U]). 90 Hands met the electrodiagnostic (EDX) criteria for mild CTS. The Sensory Thumb (M-R) was abnormal in 90% of the hands followed in order by Mix Palm (M-U) 61%, Sensory Digits (M-U) 42% and Sensory Palm (M-U) 33%. All differences were statistically significant (p < .01). Sensory Palm (M-U) did not significantly add to the diagnosis of CTS. The Sensory Thumb (M-R) was relatively the most sensitive followed by Mix Palm (M-R) was relatively the most sensitive followed by Mix Palm (M-U), Sensory Digits (M-U) and Sensory Palm (M-U).
本前瞻性研究旨在评估一种通过比较腕部正中神经-尺神经感觉潜伏期差异（掌心感觉[M-U]）来诊断腕管综合征（CTS）的技术，并比较其他先前报道技术的相对敏感性：正中神经-桡神经感觉差异（拇指感觉[M-R]）、正中神经-尺神经混合掌心差异（混合掌心[M-U]）和正中神经-尺神经感觉指差异（感觉手指[M-U]）。90只手符合轻度CTS的电诊断（EDX）标准。90%的手拇指感觉（M-R）异常，其次是混合掌心（M-U）61%、感觉手指（M-U）42%和掌心感觉（M-U）33%。所有差异均具有统计学意义（p<0.01）。掌心感觉（M-U）对CTS的诊断没有显著帮助。拇指感觉（M-R）相对最敏感，其次是混合掌心（M-R）相对最敏感，其次是混合掌心（M-U）、感觉手指（M-U）和掌心感觉（M-U）。
