Brief Summary
Pain is a subjective feeling,and pain experts have been trying to assess it using objective methods. Pain index (PI) is extracted from electroencephalographic as an objective diagnostic tool for chronic pain. This study is a diagnostic test aims to explore the reliability and validity of PI, with numerical rating scale(NRS) as the gold standard.

Outcome Measures
Primary Outcomes (1)
Pain index
Pain index is extracted from EEG accessed by a multifunctional monitor HXD-1
30 mins after treatment
Secondary Outcomes (1)
Hamilton Anxiety and Depression Scale(HADS)
baseline
Study Arms (1)
Pain index
Pain index will be extracted from the EEG of chronic pain patients before and after pain treatments
Interventions
Record the patients' EEG and extract pain index before and after pain treatments
Eligibility Criteria
The sample capacity calculation is based on the sensitivity/specificity of the diagnostic test allowed a minimum sensitivity of 80%, a minimum specificity of 80%, a significance level α of 0.01, an allowable error of 0.1 strictly.The estimated sample is 107 patients. Considering a predicted shedding rate of 10%, 118 patients will be enrolled.
You may qualify if:
- chronic pain patients diagnosed lumbar disc herniation, osteoarthritis or other chronic pain diseases, who will received injection therapy or shockwave therapy at clinic.
- patients age 18-80 years-old
- patients with an NRS pain score ≥ 4,
- patients who voluntarily participate in the test and sign the informed consent forms.
You may not qualify if:
- patients with central nervous system disorders, such as epilepsy, cerebral infarction, or cerebral hemorrhage,
- patients with mental disorders,
- patients with a history of long-term use of psychotropic drugs.
- patients who can't understand NRS.
