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:
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:
Chronic intractable pain is a disorder with complicated causes. The patient's quality of life is significantly reduced as a result of the patient's ongoing discomfort and the necessity for lengthy therapies. When patients don't respond well to medicine or other non-surgical treatments, spinal cord stimulation (SCS) is one of the surgical methods employed. The safety and effectiveness of SCS have previously been confirmed in numerous trials as a well-researched and clinically used therapy. However, the adjustment of SCS is complicated and its optimal effect relies on long-term regular follow-up. With the development of the internet, the investigators put forward a new system with remote and wireless SCS devices. Together with an exclusively developed mobile phone application, patients will be able to record their daily pain state and monthly health condition and make customized stimulation settings accordingly. This study is aimed to test the feasibility of this new precise management system. All participants will be randomly assigned to either interventional or control group. Participants in control group will be asked to take the conventional follow-up. Participants in interventional group will be additionally asked to take self-assessment on daily pain state and monthly health condition. The investigators hypothesized that this self-involved, closely monitored, and precisely adjusted system can significantly improve patients' quality of life in the long term and cut down both the financial expenses and time cost.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Precise management | Experimental | 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. |
|
| Conventional management | No Intervention | 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. |
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Precise management | Other | 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. |

EQ-5D-5L utility value has a minimum of 0 and a maximum of 1. Higher values mean a better health condition. | Baseline and Month 6 |
| Measure | Description | Time Frame |
|---|---|---|
| Pain Intensity: Change From Baseline in Visual Analogue Scale (VAS) at Month 1 | Pain intensity is assessed by VAS and compared with baseline VAS score. VAS has a minimum of 0 and a maximum of 10. Higher values mean a stronger pain. | Baseline and Month 1 |

After taking the stimulator implantation surgery, participants in the interventional group are asked to take conventional follow-up including 1-, 3-, 6-month post-operative. Other than that, participants will be asked to take additional self-assessments, including daily pain state and monthly health conditions.
