Background Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, which can be diagnosed by history, physical examinations and electrodiagnosis. Electrodiagnosis is most valuable way in the diagnosis of CTS and the evaluation of its severity. In addition to neuropathic pain mechanisms which play a dominant role in CTS, musculoskeletal structures caused nociceptive stimulus may also contribute to pain formation. LANSS (Leeds Assessment of Neuropathic Symptoms and Signs) is a frequently used scale to determine which mechanism (neuropathic and/or nociceptive) is more dominant.
Objectives The purpose of this retrospective study was to investigate the relationship between the electrophysiologic severity and neuropathic complaints (LANSS scale scores).
Methods Fifty patients whom were admitted to our out patient clinic at January 2014 to July 2014, aged 22-68 years and diagnosed with carpal tunnel syndrome by nerve conduction studies were included in the study. All patients were suffering from neuropathic pain and evaluted with LANSS scale. Because of indication of surgery for severe CTS, only mild to modorate CTS patients were included.
Results When compared to moderate group, LANSS scale scores of mild CTS patients were significantly higher than those of moderate group (Table 1).
Conclusions We think, in addition to complex pathogenesis of neuropathic pain, higher LANSS scores in mild cases may be related with a low pain and discomfort threshold in the first phase of nerve entrapment, which becomes higher later in CTS. Additional studies are needed to explain this complex findings.
