SCS Therapy: The Complete Guide
Part 5: Frequently Asked Questions (Detailed Answers)
About Stimulation
Q. What does the stimulation feel like?
A. It varies from person to person, but many patients describe it as:
- "A gentle buzzing or humming sensation"
- "A tingling feeling"
- "A warm sensation"
- "Something like a massage"
With today's mainstream paresthesia-free programs, some people feel no sensation at all while their pain is relieved.
Q. Can the stimulation be too strong or too weak?
A. You can adjust it yourself using the remote control. Additionally, models with automatic adjustment will optimize the stimulation automatically as you change positions or activities.
Q. Is the stimulation on 24 hours a day?
A. Most people keep it on during the day and turn it off at bedtime. However, if you have significant nighttime pain, you may leave it on while you sleep. You will find the pattern that works best for you.
About Daily Life
Q. Can I use my phone or computer?
A. Absolutely. Everyday electronic devices do not interfere with the system.
Q. Can I use an induction cooktop (IH stove)?
A. Yes. However, avoid leaning over the cooktop directly above the implant for extended periods.
Q. Will I set off airport security gates?
A. You may trigger airport security gates. Show your patient identification card and explain the situation to the security staff. A hand-held metal detector check is not a problem.
Q. Can I use hot springs or public baths?
A. Yes, once the wound has healed. However, avoid electric baths (low-frequency therapy pools).
Q. Can I drive?
A. Yes. However, wait until you are comfortable with the stimulation and have your doctor's permission. If the stimulation is distracting while driving, adjust it or turn it off temporarily.
About the Device
Q. How long does the battery last?
A.
- Rechargeable: More than 10 years (the battery itself)
- Non-rechargeable: Approximately 3 to 5 years
When the battery runs out, a replacement surgery (a relatively minor procedure) is required.
Q. Is charging a hassle?
A. It depends greatly on the type and intensity of stimulation. For paresthesia-free programs (which use higher output), charging is needed daily to every other day. For conventional programs with paresthesia (which use lower output), it is about once a week. Each session takes approximately 30 minutes to 1 hour using a dedicated external charger placed on the skin. See the charging frequency table in Part 1 for more details.
Q. Can the device malfunction?
A. A large-scale study in 2004 (Cameron, 2,700 cases) reported the following complications:
- Lead migration: 13.2%
- Lead fracture: 9.1%
- Infection: 3.4%
- Hardware failure: 1.3%
However, this data is from 2004. Since then, improvements in both devices and surgical techniques have led to a downward trend in these complication rates. All of these complications can be addressed with reoperation or programming adjustments.
About Effectiveness
Q. Can the effect weaken over time?
A. The effect may diminish over time (a phenomenon called habituation). In that case, the following options are available:
- Adjusting the stimulation settings
- Changing the stimulation mode
- Adding or replacing leads
These measures are often effective in restoring relief.
Q. Can I stop SCS treatment?
A. Yes, you can. If the treatment is not effective or you wish to stop for any reason, the device can be removed. There is no significant lasting impact on your body.
