Overview
High-frequency spinal cord stimulation is a form of SCS that delivers electrical pulses at a much higher frequency (commonly 10 kHz) than traditional systems. Many patients do not feel the tingling (paresthesia) associated with traditional stimulation.
Like other SCS systems, it is used for certain chronic back and leg pain conditions and painful diabetic neuropathy, and it begins with a temporary trial.

How it works
Leads are placed in the epidural space and connected to a generator that delivers high-frequency pulses. These pulses are thought to modulate pain signaling in the spinal cord without producing a tingling sensation.
Who it may be for
- Chronic back and/or leg pain
- Persistent pain after spine surgery
- Painful diabetic neuropathy
- Patients who prefer a therapy without tingling
Your exam and imaging decide whether this treatment is appropriate for you.
What to expect
- Trial: temporary leads for several days.
- Decision: review of pain and function changes.
- Implant: permanent system if the trial is successful.
Recovery
Activity restrictions are typical for several weeks after an implant to allow the leads to settle. Your instructions may differ.
Risks and side effects
Every procedure has risks. Your physician will review them with you, including:
- Infection
- Lead movement
- Bleeding
- Pain at the generator site
- Device malfunction
Insurance and cost
Many plans, including Medicare, may cover this treatment when criteria are met. We verify benefits before scheduling. See accepted insurance.
Frequently asked questions
How is high-frequency SCS different?
It uses a higher frequency and usually does not cause tingling. Whether it is the best option for you depends on your condition.
Will I feel the stimulation?
Most people do not feel high-frequency stimulation.
Is there a trial first?
Yes. A temporary trial is standard before a permanent implant.
