Background: This study aims to investigate the relationship between electrophysiologic severity and several clinical severity scales in patients with carpal tunnel syndrome (CTS).
Methods: Two hundred patients with documented CTS were enrolled. The severity of electrophysiologic impairment was classified by Padua scale. The main outcome measures were assessed with several clinical scales which were categorized into two groups: Patient questionnaire consisted of Symptom Severity Scale (SSS), Functional Status Scale (FSS), and faces pain scale. Physician-based quantitative clinical scale was Historical-Objective (Hi-Ob) scale. The electrophysiologic severity was compared with clinical scales, respectively.
Results: Clinical severity assessments using SSS, FSS and pain scale showed weak correlation with electrophysiologic severity of CTS. However, Hi-Ob scale was moderately correlated with electrophysiologic severity of CTS.
Conclusions: Electrophysiologic severity of CTS was more correlated with physician-measured clinical scale than patient-oriented symptom scales
