A Multi-center Clinical Longitudinal Study of Neuropathic Pain by Collecting Data

Condition(s) studied

Investigational drug(s) / intervention(s)

A multi-center clinical longitudinal study of neuropathic pain by collecting data on patients' brain physiology and cognitive function: Using the use of pain visual analog scale (VAS), digital pain grading method (NRS), neuropathic pain assessment scale (DN4), sleep quality (Pittsburgh sleep quality index, Ascens insomnia scale), social support assessment scale (SSQ), Montreal cognitive assessment scale (MoCA), Barrett impulse scale (BIS), anxiety and depression score (GAD-7, PHQ-9), emotional tasks, cognitive function (N-back, time perception, delay-discount), electroencephalogram (EEG), near-infrared brain function imaging (fNIRS) and other indicators to study the dynamic changes of various factors in the process of acute pain.

Eligibility

Primary outcome measure(s)

• Visual Analogue Scale/Score（VAS） — 1 month
  VAS pain score criteria ((0-10 points) 0 Points: painless; 3 points below: have a slight pain, can tolerate; 4 points- -6 points: patients with pain and affect sleep, and can still tolerate; 7 points-10 points: the patient has gradually intense pain, the pain is unbearable, affect appetite, affect sleep.
• digital pain grading method (NRS) — 1 month
  Score ranged from 1 to 5, and the higher the score, the more it suggested the possibility of neuropathic pain. Clinically, when patients score ID Pain 3, neuropathic pain-related treatment options will be considered.
• neuropathic pain assessment scale (DN4) — 1 month
  Each assessment item was assigned 1 point for "yes" and 0 point for "no". The total score of DN4 is 0 to 10, and neuropathic pain when the total score is greater than or equal to 4.
• sleep quality (Pittsburgh sleep quality index, Ascens insomnia scale) — 1 month
  The PSQI was used to assess the sleep quality of the participants in the last 1 month. It consists of 19 self-assessment entries and 5 items, among which the 19th self-assessment entry and 5 items do not participate in the scoring. Only the 18 self-assessment entries participating in the scoring are introduced here (see the attached questionnaire for details). The 18 items formed 7 components, and each component was scored according to 0-3 levels. The cumulative score of PSQI total score ranged from 0 to 2 l. The higher the score, the worse the sleep quality.
• EEG — 1 month
  To study the dynamic change of EEG wavelength during the progression from acute pain to chronic pain，four basic waveforms, α, β, θ, δ wave, were collected。
• Barrett impulse scale (BIS) — 1 month
  The subject's feeling, reaction and degree of recognition are regarded as evaluation indicators, and the five-point scale classification method is adopted. Action impulse is scored positively, and unplanned impulse and cognitive impulse are scored in reverse. The standard is: "1" means never or almost never; "2" means occasional; "3" means often; "4" means always or almost always.
• (Generalized Anxiety Disorder,GAD-7) — 1 month
  Each entry is 0 to 3 points, the total score is the score of the 7 items, the total score ranges from 0 to 21 points A 0-4 score is found without a GAD And 5-9 points for mild GAD And 10 - 14 points for moderate GAD 15 - 21 for severe GAD
• (Patient Health Questionnaire-9 — 1 month
  Calculate the total score 0-4 points: no depression (take care of yourself) 5-9: possible mild depression (consult a psychologist or medical worker recommended) 10-14 points: There may be moderate depression (preferably consult a psychologist or psychological medicine worker) 15-19: possible moderate to severe depression (consult a psychiatrist or psychiatrist) 20-27: possible severe depression (be sure to see a psychologist or psychiatrist) Core project points Item 1, item 4, item 9, any question score\> 1 (select 2,3), need attention; item 1, item 4, representing the core symptoms of depression; Item 9 represents a self-injury mind.
