Design outcomes

Primary

Measure	Time frame
The changes in resting-state brain functional networks of chronic pain patients	—

Secondary

Measure	Time frame
1) Correlation between the changes in functional connectivity of brain networks and the intensity of pain 2) Correlation between the changes in functional connectivity of brain networks and psychological indicators (i.e. anxiety, depression, pain catastrophising, consistency, insomnia, impulsivity). 3) Correlation between the DMN and other brain networks in chronic pain patients	—
