APP-based Precise Management System of Chronic Intractable Pain

The goal of this clinical trial is to learn about a new management system in chronic and stubborn pain patients who accept therapy of spinal cord stimulation (SCS). Usually, these patients are required to take long-term follow-ups to ensure that the stimulator works well. The main questions it aims to answer are:Is it better to improve the patient's quality of life than the current conventional follow-up?Is it better to relieve pain in the long term than the current conventional follow-up?Is it possible to be applied to a large population of chronic pain patients? Participants will be randomly assigned to either a control group or an interventional group.Participants in the control group will be given the standard SCS implantation surgery and asked to complete the conventional follow-up (at least 1-, 3-, and 6-month post-operative).Participants in the interventional group will be given the standard SCS implantation surgery and asked to do the following things:Take the daily pain self-assessment questions on a mobile phone APP.Take the monthly healthy status self-assessment questionnaires on a mobile phone APP.Take the conventional follow-up (at least 1-, 3-, and 6-month post-operative). Researchers will compare the two groups to see if the life quality of the interventional group is improved.
