Brief summary
By the method of multi-mode Magnetic Resonance Imaging, 5 patients with knee osteoarthritis are selected in this trial to observe the possible differences in the brain structure and function from the 5 healthy volunteers.
Detailed description
In this study, 5 patients with knee osteoarthritis and 5 healthy volunteers were selected. The degree of pain is evaluated via visual analogue pain scale (VAS). The emotional state is evaluated by Hamilton anxiety scale (HAMA) or Hamilton depression scale (HAMD). The patients and healthy volunteers who meet the include criteria are include in the research. Then the spontaneous brain electrical activity is collected by multimodal brain magnetic resonance imaging technology. The spontaneous brain electrical activity is analyzed to find the differences between knee osteoarthritis patients and healthy volunteers. Further analysis of resting brain functional connectivity and information exchange changes in multifunctional areas, in order to elaborate the central mechanism of pain and emotion modulation.

| Measure | Time frame | Description |
|---|---|---|
| blood-oxygen-level dependent (BOLD) signal | the data will be collected the second day when entering group | BOLD is used in functional magnetic resonance imaging (fMRI) to observe different areas of the brain or other organs, which are found to be active at any given time. The hemoglobin content, blood flow volume and oxygen consumption of special brain regions will be observed via BOLD. Oxyhemoglobin ratio is used in this measurement. |
