Abstract

Background: The primary objective of this study was to determine the association between preoperative electrodiagnostic study (EDS) parameters and Patient-Reported Outcomes Measurement Information System (PROMIS) instruments in patients with EDS-confirmed carpal tunnel syndrome (CTS).

Methods: A retrospective study of 45 patients with EDS-confirmed CTS was conducted. Patients completed the PROMIS Upper Extremity, PROMIS Pain Interference and PROMIS Pain Intensity. Explanatory variables included EDS disease severity (mild, moderate and severe), sensory peak latency, sensory amplitude, motor latency, motor amplitude, the presence of nonrecordable sensory latency and the presence of nonrecordable sensory amplitude. Explanatory variables also included patient-related factors, such as age, sex and diabetes mellitus. Associations between variables were assessed using simple linear regression, analysis of variance (ANOVA) and Student’s t-test.

Results: In our cohort, the EDS severity was mild in 38%, moderate in 42% and severe in 20% of patients. The mean PROMIS Upper Extremity score was 44.4, the mean PROMIS Pain Interference score was 53.5 and the mean PROMIS Pain Intensity score was 49.9. Bivariate analysis demonstrated no association between EDS severity overall or any EDS parameter individually and PROMIS Upper Extremity, PROMIS Pain Interference and PROMIS Pain Intensity. Diabetes mellitus was associated with poorer PROMIS Upper Extremity scores.

Conclusions: EDS severity is not associated with PROMIS Upper Extremity, PROMIS Pain Interference and PROMIS Pain Intensity. Carpal tunnel release is commonly indicated for pain and dysfunction, but validated measures of pain and dysfunction do not correlate with EDS severity.

Level of Evidence: Level III (Diagnostic)
