Brief Summary

Neuropathic pain, described as 'pain arising as a direct consequence of a lesion or disease on the somatosensory system', affects up to 3-9.8% of the investigators' population, but is often underdiagnosed and undertreated. As treatment is different for patients with neuropathic pain and nociceptive pain, it is important to screen for neuropathic pain. Commonly employed questionnaire-based diagnostic tools in English speaking countries include the Leeds Assessment of Neuropathic Symptoms and Signs pain scale (LANSS) and Neuropathic pain questionnaire (NPQ). Self-completed LANSS is particularly useful as it is not restricted to clinician's examination and can be applied in large-scale research. S-LANSS has been successfully translated, validated and used successfully in Arabic and Turkish, but it has not been utilised in the Chinese population. As verbal translations of the English questionnaires used at the bedside may be prone to errors in interpretation and requires medical practitioners to interpret the questions. Therefore a translation and validation study is essential.

Outcome Measures

Primary Outcomes (1)

  • Questionnaire can successfully identify subjects with neuropathic pain, or nociceptive pain

    One year from commencement of study

Study Arms (2)

Neuropathic pain subjects

The diagnosis of neuropathic pain will be made by pain specialists based on a detailed history, physical examination, investigation results and medical records.

Other: Questionnaire

Nociceptive pain subjects

The diagnosis of nociceptive pain will be made by pain specialists based on a detailed history, physical examination, investigation results and medical records.

Other: Questionnaire

Eligibility Criteria

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

A total of 200 pain patients will be recruited. One hundred of these patients will be patients suffering from neuropathic pain, and 100 will be patients with nociceptive pain. The diagnosis of neuropathic or nociceptive pain will be made by pain specialists based on a detailed history, physical examination, investigation results and medical records. The pain specialists' diagnosis will be used for distinguishing between nociceptive and neuropathic pain. Demographic information including age, sex, pain diagnosis and duration, education level, co-existing medical problems and employment status will be recorded. The Cantonese S-LANSS will then be administered to patients to be completed without the help of staff.

You may qualify if:

  • Native Chinese-Cantonese speaker
  • Aged 18 to 80
  • Presence of pain for more than 3 months
  • Able to understand, read and write Traditional Chinese
  • Able to give informed written consent
  • Ability to complete the questionnaire

You may not qualify if:

  • Patients who require active pain treatment and / or intervention within 1 week after the initial consultation
  • Voluntary withdrawal from study at any stage
