Summary of Various Neuropathic Pain Questionnaires

NPQ [38] DN4 [39] LANSS [40] ID pain [41] painDETECT [42]
1. Burning × 0.006 Question 1a Pain questionnaires 1. Pins and needles (Yes: 1, No: 0) 1. Grading of pain (0: never, 1: hardly, 2: slightly, 3: moderately, 4: strongly, or 5: very strongly noticed)
2. Overly sensitive to touch × 0.005 1. Burning 1. Dysesthesia (Yes: 5, No: 0) 2. Hot/burning sensation (Yes: 1, No: 0) 2. The pain course pattern (0: persistent pain with slight fluctuations, –1: persistent pain with pain attacks, +1: persistent pain without pain between attacks, or +1: persistent pain with pain between attacks)
3. Shooting pain × 0.005 2. Painful cold 2. Color change of the skin in the painful area (Yes: 5, No: 0) 3. Numbness (Yes: 1, No: 0) 3. Radiating pain (+2: yes, or 0: no)
4. Numbness × 0.020 3. Electric shocks 3. Abnormal sensitivity to touch in the affected skin (Yes: 3, No: 0) Electric shocks (Yes: 1, No: 0) The total score varies from 0 to 8.
5. Electric pain × –0.008 Question 2a 4. Abnormal skin temperature change in the painful area (Yes: 2, No: 0) Worsening with touch (Yes: 1, No: 0)
6. Tingling × 0.010 4. Tingling 5. Abnormal skin temperature change (Yes: 1, No: 0) Limited to the joints (Yes: –1, No: 0)
7. Squeezing × –0.004 5. Pins and needles The sensory testing The total score varies from –1 to 5.
8. Freezing × 0.004 6. Numbness 1. Allodynia (Yes: 5, No: 0)
9. Unpleasant × 0.006 7. Itching 2. An altered pin-prick threshold (Yes: 3, No: 0)
10. Overwhelming × –0.003 The total score varies from 0 to 24.
11. Tactile hyperalgesia × 0.006 Question 3b If the score < 12, neuropathic mechanisms are unlikely to be contributing to the patient’s pain.
12. Increased pain due to weather changes × –0.005 8. Hypoesthesia to touch If the score ≥ 12, neuropathic mechanisms are likely to be contributing to the patient’s pain.
If the total score minus 1.408 is below 0, it predicts non-neuropathic pain. 9. Hypoesthesia to pinprick
On the contrary, if the total score minus 1.408 is at or above 0, it predicts neuropathic pain. Question 4b
10. Pain caused by or increased by brushing
Yes = 1, No = 0
Patient’s score = □/10
