SCS Therapy: The Complete Guide
Part 2: Understanding the Different Stimulation Modes
The Current Trend: Paresthesia-Free Programs Are Now Mainstream
SCS stimulation methods have evolved significantly. Previously, the main approach was conventional stimulation, which "covers pain with a tingling sensation." Today, newer programs that produce no noticeable sensation are used preferentially.
Conventional Stimulation (With Paresthesia)
This is the longest-established method and remains an effective option.
| Feature | Details |
|---|---|
| Sensation | A tingling, buzzing, or vibrating feeling (paresthesia) |
| How it works | Covers the painful area with stimulation sensations |
| Advantage | Long track record; the effect is easy to feel |
| Power consumption | Relatively low (less frequent charging) |
Paresthesia-Free Programs
These are now the mainstream approach. They include high-frequency stimulation and several other technologies.
| Feature | Details |
|---|---|
| Sensation | Little to no stimulation felt |
| How it works | Acts on the pain signal processing itself |
| Advantage | Feels natural because there is no tingling; less interference with daily life |
| Power consumption | Higher than conventional (charging is somewhat more frequent) |
Automatic Adjustment Based on Body Movement
This feature automatically adjusts the stimulation intensity according to your posture and activity.
| Feature | Details |
|---|---|
| How it works | Detects spinal cord electrical activity or body movement and adjusts automatically |
| Advantage | Optimal stimulation is maintained whether you are standing, sitting, or moving around |
| Availability | Available on certain Medtronic models |
Which Stimulation Mode Should You Choose?
| Your situation | Recommendation |
|---|---|
| Receiving SCS for the first time | A paresthesia-free program is often tried first |
| Paresthesia-free program is not effective enough | Conventional stimulation is also tried |
| You are very active (bothered by stimulation changes) | A model with automatic adjustment |
In practice:
During the trial period, you will often try multiple modes and find the one that works best for you. We recommend experiencing both "programs with paresthesia" and "programs without paresthesia" before making your decision.
