Abstract

Background Carpal tunnel syndrome (CTS) is an entrapment neuropathy of the median nerve and can cause neuropathic pain and functional decrease in hand functions.

Objectives The aim of this study was to compare the effectivity of Leeds assessment of neuropathic symptoms and signs scale (LANSS) with pain detect questionnaire (PDQ) in CTS and their relations with hand functions.

Methods The patients were selected among the patients who admitted to physical medicine and rehabilitation outpatient clinics and the selection criteria was to have positive Tinel or Phalen sign and paresthesia in hand. 157 hands of 90 patients were evaluated by electromyography and grouped as mild, moderate or severe involvement. Neuropathic pain was analysed by LANNS and PDQ; hand functions by Duruöz hand index (DHI); sensory evaluations by Semmes Weinstein monofilaments (SWM) and grip strength by Jamar dynamometer.

Results EMG findings revealed 30.4% of hands had mild, 66.5% had moderate and 2.5% had severe CTS. In statistical evaluations in order to have a homogenous group, we have chosen the moderate CTS group. LANSS scores correlated with DHI, Jamar scores (p and r values were 0.032, 0.209; 0.010, -0.250 respectively. PDQ scores correlated with VAS score, DHI, Jamar, SWM (p and r values were 0.001, 0.314; 0.000, 0.346; 0.005, -0.270; 0.000, 0.391). The correlation coefficient between LANSS and PDQ was p: 0.000; r: 0.324.

Conclusions Though there is a significant correlation between LANSS and PDQ scores, PDQ scores revealed better correlation coefficients in DHI and Jamar scores and additional correlations were determined in VAS scores and SWM values.In conclusion we think PDQ presents finer results then LANNS.
