APP-based Precise Management System of Chronic Intractable Pain (PreMaSy)
Precise Management System (PreMaSy) of Chronic Intractable Pain Based on a Remote and Wireless Spinal Cord Stimulation System
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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Precise management
Participants will be asked to take daily pain state and monthly health condition assessments. A warning for the physicians will be given when participants reach daily assessment threshold. Remote interventional meeting will be scheduled and stimulation parameters will be adjusted accordingly. Participants will also be asked to take conventional follow-up at 1-, 3-, and 6-month post-operative. |
The daily pain state assessments contain three components, the visual analogue scale (VAS) based on pain intensity, time-intensity curve throughout the day, and pain locations.
The VAS scores from the first seven post-operative days will be collected as the baseline data.
The interventional threshold will be determined by adding 30 mm (if the scale length were 100 mm) to the baseline mean.
If participants score above the threshold three times in a row, a warning will be sent to their physicians.
A remote meeting will be scheduled and stimulation settings will be adjusted accordingly.
|
No Intervention: Conventional management
Participants will be only asked to take conventional follow-ups at 1-, 3-, and 6-month post-operative.
During these follow-ups, they will be asked to score VAS based on general pain state, and take questionnaires including EQ-5D-5L, PSQI, PGIC, CGI-I.
