What Is CET Therapy? A Complete Guide to Combined Electrochemical Treatment
If you or someone you love has been living with peripheral neuropathy — the burning, numbness, tingling, and weakness that makes everyday life a challenge — you may have come across the term CET therapy. But what exactly is it, and why are so many neuropathy patients finally finding lasting relief through this approach?
CET, or Combined Electrochemical Treatment, is an FDA-cleared, non-surgical treatment protocol designed specifically to address the root cause of peripheral neuropathy: damaged nerve fibers. Rather than simply masking symptoms with pain medications, CET works at the nerve level — stimulating regeneration, restoring circulation, and normalizing nerve signaling.
At New Promise Neuropathy, CET is the foundation of our entire treatment approach, and for good reason. In appropriate candidates, clinical results show an 80–85% success rate in achieving meaningful, lasting relief.
The Science Behind CET Therapy
To understand why combined electrochemical therapy works, it helps to understand what goes wrong with neuropathy in the first place.
Peripheral nerves are long, delicate structures responsible for transmitting signals between your brain and the rest of your body. When these nerves are damaged — by diabetes, chemotherapy, injury, autoimmune disease, or other causes — they either fire incorrectly (producing pain and hypersensitivity) or fail to fire at all (producing numbness and weakness). Traditional medications work downstream, attempting to suppress these faulty signals. CET works upstream, targeting the damaged nerve tissue directly.
Combined Electrochemical Treatment brings together two clinically proven components:
Component 1: Electronic Signal Treatment (EST)
The centerpiece of CET is Electronic Signal Treatment — a sophisticated technology that delivers precisely calibrated electronic signals through specialized electrode pads placed on the skin over affected areas. These are not generic TENS pulses. The device generates multi-frequency waveforms specifically tuned for peripheral nerve tissue.
When these signals penetrate the treatment area, they:
- Stimulate nerve cell repair — activating the natural regenerative processes within damaged axons (nerve fibers)
- Restore nerve-to-nerve communication — improving signal transmission across damaged synaptic junctions
- Boost microcirculation — increasing blood flow to deliver oxygen and nutrients to nerve tissue that has been starved of proper circulation
- Reduce abnormal pain signaling — normalizing the erratic electrical activity in damaged nerves that generates burning, shooting, and tingling pain
- Enhance cellular metabolism — increasing the energy available within nerve cells to support repair and maintenance
Unlike TENS units or basic electrical stimulation devices, the EST device used in CET delivers a complex, therapeutic signal that has been developed specifically for nerve regeneration — not just temporary pain interruption.
Component 2: Regional Nerve Blocks
The second component of combined electrochemical therapy involves targeted superficial nerve blocks administered to the treatment area. These serve several important functions:
- Reducing inflammation around compressed or irritated nerves
- Providing immediate pain relief by interrupting the pain signal loop
- Creating an optimal healing environment by decreasing swelling that physically impedes nerve recovery
- Priming nerve tissue to be more receptive to the electronic signal treatment that follows
Together, these two components make CET significantly more effective than either approach used in isolation. The nerve block clears the path; the EST drives the repair.
What to Expect During a CET Treatment Session
One of the most common questions patients have is: what does a CET session actually feel like?
A typical CET treatment session at New Promise Neuropathy follows a consistent, structured protocol:
- Pre-treatment assessment — Your provider evaluates your current symptom levels and tracks progress since your last session using objective measurements.
- Regional nerve block administration — Targeted superficial injections are delivered to affected areas to reduce inflammation and prepare the nerves.
- Electrode placement — Specialized electrodes from our EST device are positioned on the skin over the treatment area — typically the feet, lower legs, hands, or arms depending on where your neuropathy is located.
- EST delivery — Calibrated electronic signals are delivered at therapeutic frequencies. Most sessions last approximately 20 minutes for the EST component.
- Post-session review — Your provider discusses your response and adjusts your treatment plan as needed.
Is CET therapy painful? The vast majority of patients describe the EST portion as comfortable — even relaxing. Common sensations include a gentle tingling, a warm pulsing feeling, or mild muscle twitching as nerves respond to the signals. There is no cutting, no anesthesia, and no recovery time required. Patients drive themselves home and return to normal activities immediately after each session.
Clinical Evidence and Success Rates
CET therapy has a strong track record in clinical practice for peripheral neuropathy patients who meet the appropriate candidacy criteria. At New Promise Neuropathy, our outcomes show an 80–85% success rate among qualifying patients — meaning the large majority experience clinically meaningful reductions in pain, improvements in sensation, and gains in quality of life.
Outcomes that patients commonly experience include:
- Significant reduction in burning, tingling, and stabbing pain
- Return of sensation in previously numb areas (feet, toes, hands)
- Documented improvements in nerve function on objective testing
- Better balance, coordination, and lower fall risk
- Improved sleep quality due to reduced nighttime pain
- Greater ability to perform daily activities without limitations
Results are typically progressive — many patients notice improvement beginning within the first few sessions, with continued gains building over the full course of treatment.
Who Is a Good Candidate for CET Therapy?
Combined electrochemical therapy is effective across a wide range of neuropathy types and causes. Patients who commonly benefit include those with:
- Diabetic peripheral neuropathy — one of the most common causes of nerve damage in the U.S.
- Chemotherapy-induced peripheral neuropathy (CIPN) — nerve damage resulting from cancer treatment
- Idiopathic peripheral neuropathy — nerve damage without a clearly identified cause
- Neuropathy from injury or nerve compression
- Autoimmune-related peripheral neuropathy
- Post-surgical neuropathy
The best way to determine whether CET neuropathy treatment is right for your specific situation is a thorough evaluation with one of our specialists. During your initial consultation, we assess your symptom profile, nerve function, medical history, and overall health to determine candidacy and develop a personalized treatment plan.
How CET Differs from Other Neuropathy Treatments
Many patients come to New Promise Neuropathy after spending years cycling through treatments that provided little lasting relief. Understanding how CET compares helps explain why it produces different outcomes.
| Treatment | Approach | Limitations | |---|---|---| | Medications (gabapentin, Lyrica, etc.) | Suppress pain signals in the brain | Mask symptoms only; do not repair nerves; significant side effects | | TENS units | Basic electrical stimulation for temporary pain relief | Not calibrated for nerve repair; effects are temporary | | Surgery | Nerve decompression for specific conditions | Invasive; not appropriate for most neuropathy types; significant recovery | | CET therapy | Stimulates nerve repair and regeneration at the source | Non-invasive, no downtime, targets root cause |
CET is fundamentally different because it is designed for nerve repair — not symptom management. The goal is to restore nerve function, not indefinitely suppress the signals that damaged nerves produce.
New Promise Neuropathy's Approach to CET
At New Promise Neuropathy, every CET treatment plan begins with a comprehensive evaluation by a board-certified physician or licensed nurse practitioner. We do not take a one-size-fits-all approach. Treatment protocols — including the number of sessions, frequency, and specific parameters — are personalized based on the type and severity of your neuropathy, your overall health profile, and how you respond to treatment.
Our clinics are located throughout DFW and South Texas, including Arlington, Frisco, Fort Worth, Denton, Las Colinas, Tyler, Weatherford, Sherman, Colleyville, and Burleson — with locations open or opening soon in Spring, TX and Missouri City, TX.
We believe patients deserve more than a prescription and a follow-up appointment. CET therapy gives us a tool to actually address what is happening to your nerves — and give you a real path toward recovery.
Frequently Asked Questions About CET Therapy
How does combined electrochemical therapy work? CET combines two components: Electronic Signal Treatment (EST), which delivers precisely calibrated electrical signals to stimulate nerve repair and improve circulation, and regional nerve blocks that reduce inflammation and prepare the nerve tissue. Together, they work at the root cause of neuropathy rather than masking symptoms.
What is the success rate of CET therapy for neuropathy? In appropriate candidates, New Promise Neuropathy achieves an 80–85% success rate — meaning the large majority of qualifying patients experience meaningful improvements in pain, sensation, and function.
How many CET sessions are needed? The number of sessions varies based on the type and severity of your neuropathy. Your provider will develop a personalized treatment plan during your initial consultation. Most patients complete a series of sessions over several weeks, with progress assessed throughout.
Is CET therapy painful? The EST component of CET is non-invasive and most patients describe it as comfortable — a gentle tingling or warm pulsing sensation. There is no surgery, no general anesthesia, and no recovery downtime.
What types of neuropathy does CET treat? CET is used for diabetic neuropathy, chemotherapy-induced peripheral neuropathy, idiopathic neuropathy, neuropathy from injury or compression, autoimmune neuropathy, and other forms of peripheral neuropathy.
