What Is Scrambler Therapy?
Scrambler Therapy — also marketed as Calmare® — is a non-invasive, drug-free treatment for chronic neuropathic pain that uses surface electrodes to send 'no-pain' signals along the same nerves carrying pain to the brain.
How Scrambler Therapy works
A trained provider places small electrodes on the skin near the painful area. The Scrambler / Calmare® device generates low-intensity electrical signals that mimic the body's own "non-pain" nerve impulses. Over a series of sessions, the brain learns to re-interpret signals from the affected nerves as normal sensation rather than pain.
Conditions it's used for
- Chemotherapy-induced peripheral neuropathy (CIPN)
- Diabetic peripheral neuropathy
- Post-herpetic neuralgia (shingles pain)
- Complex Regional Pain Syndrome (CRPS)
- Failed back surgery syndrome and chronic low back pain
- Post-surgical neuropathic pain
- Cancer-related pain
What a typical treatment looks like
A standard course is 10 consecutive weekday sessions, each lasting about 30–45 minutes. Many patients report meaningful pain reduction within the first few sessions. Booster sessions may be recommended if pain returns months later.
Is it safe?
Scrambler Therapy is non-invasive and drug-free. The most commonly reported sensation is a mild tingling at the electrode sites. It is FDA-cleared and has been studied at major cancer centers including Mayo Clinic and Johns Hopkins.
