“…The exclusion criteria for participation were CTS patients, diabetic patients, history of wrist surgery or wrist fracture. All participants were free of signs and symptoms of CTS, as indicated by screening tests including the Boston Carpal Tunnel Questionnaire, Phalen Test, and CTS Tinel Test [ 14 – 16 ]. The physical anthropology characteristic of participants such as height, weight and wrist circumference were presented in Table 1 .…”

This study investigated the effects of wrist angle, sex, and handedness on the changes in the median nerve cross-sectional area (MNCSA) and median nerve diameters, namely longitudinal diameter (D1) and vertical diameter (D2). Ultrasound examination was conducted to examine the median nerve at the proximal carpal tunnel in both dominant and nondominant hands of men (n = 27) and women (n = 26). A total of seven wrist angles were examined: neutral; 15°, 30°, and 45° extension; and 15°, 30°, and 45° flexion. Our results indicated sexual dimorphism and bilateral asymmetry of MNCSA, D1 and D2 measurements. MNCSA was significantly reduced when the wrist angle changed from neutral to flexion or extension positions. At flexion positions, D1 was significantly smaller than that at neutral. In contrast, at extension positions, D2 was significantly smaller than that at neutral. In conclusion, this study showed that MNCSA decreased as the wrist angle changed from neutral to flexion or extension positions in both dominant and nondominant hands of both sexes, whereas deformation of the median nerve differed between wrist flexion and extension.

“…Electrodiagnostic findings have also been compared with scores on the DASH. Bakhsh et al, 22 in a 2012 study, found no correlation between DASH scores and individual electrodiagnostic parameters. The authors did not provide any electromyographic data, and as such the correlation of DASH score with nerve conduction parameters is of limited value relative to the categorization of CTS severity.…”

Background:Electrophysiologic studies including electromyography and nerve conduction studies play a role in the evaluation of carpal tunnel syndrome (CTS), despite evidence that these studies do not correlate with CTS-specific symptom scores. There is a lack of evidence comparing electrophysiologic data with general measures of function.Methods:Fifty patients presenting for CTS treatment over an 8-month period were analyzed retrospectively. All patients completed surveys including the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH) and the Medical Outcomes Study 12-Item Short-Form Survey [(physical component summary 12, mental component summary (MCS-12)]. Electromyography and nerve conduction studies were performed on all patients and compared with outcome scores.Results:Analysis demonstrated no relationship between DASH or MCS-12 and electrodiagnostic severity. No significant correlations were noted between DASH or MCS-12 and median motor or sensory latency. There was a moderate–weak correlation (rho = 0.34) between more severe electrophysiologic grade and better function based on physical component summary 12.Conclusions:Electrodiagnostic severity grades do not correlate with patient-reported disability, including the DASH and MCS–12 surveys. There is a counterintuitive correlation between more-severe electrodiagnostic findings and decreased physical disability. These findings indicate that disability may not correlate with electrodiagnostic severity of median neuropathy in CTS.
