Higher Diagnostic Yield With the Combined Sensory Index in Mild Carpal Tunnel Syndrome

Abstract

Our data suggest that the CSI algorithm is significantly more effective than the D2 to diagnose mild CTS. If mild CTS is diagnosed earlier, treatment can be initiated sooner and morbidity can likely prevented.

Effect of Carpal Tunnel Syndrome on the Ulnar Nerve at the Wrist

“…For electrodiagnosis, we used the American Association of Neuromuscular and Electrodiagnostic Medicine criteria for carpal tunnel syndrome diagnosis and the Padua scale for severity classification. Recently, a more effective diagnostic tool using a combined sensory index in mild carpal tunnel syndrome was reported 21 . Thus, some of the control hands may have been misclassified because there is a possibility that they had asymptomatic median neuropathy.…”

“…Recently, a more effective diagnostic tool using a combined sensory index in mild carpal tunnel syndrome was reported. 21 Thus, some of the control hands may have been misclassified because there is a possibility that they had asymptomatic median neuropathy. This factor could have affected the subsequent electrodiagnostic test results by falsely reducing the differences in both median and ulnar nerve results for the carpal tunnel syndrome group versus the control group.…”

Does electrodiagnostic evidence correlate with mood and function in patients with a pre-diagnosis of carpal tunnel syndrome?

“…In a similar study, the mean BDI score of the patients was 10.38 in nonneurological hand pain group and 5.38 in patients with CTS [19] but in our study it was above 15 for all groups. There is no data to show that BDI scores are higher in Turkish population, or there are no baseline data for depression of the population that are referred to our EMG laboratory.…”

Electrosonodiagnosis in Carpal Tunnel Syndrome: A Proposed Diagnostic Algorithm Based on an Analytic Literature Review

“…Evidence reviewed above indicates that measuring the CSI and using an upper limit of normal of 1.1 milliseconds yields a specificity and positive predictive value of 100% for the detection of FMMW, making EDx a suitable confirmatory test for CTS [2,8,59,60].…”

“…Abbreviations: CTS ¼ carpal tunnel syndrome; CSA ¼ cross-sectional area; WFR ¼ wrist-to-forearm ratio of median nerve CSA. of 100% for the detection of FMMW, making EDx a suitable confirmatory test for CTS [2,8,59,60].…”
