The frequency of neuropathic pain in a multi-ethnic population is lower than other populations

The occurence of neuropathic pain greatly varies among various ethnic groups. Kew Y et al conducted a study to find out the frequency and associations of neuropathic pain in a multi-ethnic cohort of Asian low back pain (LBP) patients. This was a cross-sectional study of LBP patients observed at the University of Malaya Medical Centre, Kuala Lumpur, Malaysia.

Neuropathic low back pain patients were recognized via the painDETECT questionnaire and compared with non-neuropathic (unclear or nociceptive) LBP patients, in terms of socio-demographic and clinical factors, pain severity (numerical pain rating scale, NPRS), disability (Roland Morris Disability Questionnaire, RMDQ), plus anxiety and depression (Hospital Anxiety and Depression Scale, HADS).

Out of 210 patients, 26 (12.4%) were reported to have neuropathic LBP. Neuropathic pain was found to be linked with non-Chinese ethnicity, higher body mass index and pain radiation below the knee. The patients with neuropathic pain had remarkably higher NPRS and RMDQ scores and there were more patietnts with anxiety on HADS. Nonetheless, no differences between the groups in age, gender, pain duration or underlying diagnosis of LBP were reported.

The frequency of neuropathic low back pain in a multi-ethnic Malaysian cohort is lower than previously delineated in other populations with possible differences between ethnic groups. It also has an association with greater pain severity, disability and anxiety.
