Abstract
Introduction: Diagnosis of carpal tunnel syndrome (CTS)is based on clinical symptoms, examination findings, andelectrodiagnostic studies. Recent studies have shown theefficacy of median sensory-ulnar motor latency differencewas devised as another way to improve diagnostic accuracyfor mild carpal tunnel syndrome. Current research aimed tostudy diagnostic value of Median sensory ulnar motor latencydifference (MSUMLD) in mild carpal tunnel syndromeand compare it with median-ulnar (MU) sensory and motorlatency differences.Material and methods: 100 hands of CTS were studied andafter a detailed history and physical examination, routine testsand nerve conduction study was done .In mild CTS cases notdetected by routine NCS, MSUMLD was calculated and itssensitivity was compared with MU sensory and motor latencydifference.Results: It was found that Median Ulnar sensory latencydifference had the highest sensitivity.Conclusion: MSUMLD can be added as a new diagnosticparameter in detecting mild CTS with no additional testingalthough it’s sensitivity is less than Median-Ulnar sensorylatency difference
