The Science Behind NET

When people first hear about Neuro Emotional Technique, the most common question I get is a fair one: is there real evidence behind this?

After more than 30 years in practice, I think you deserve a straight answer. So here’s what the published research says, where it’s strong, and where it’s still early.

What NET is, in plain terms

Neuro Emotional Technique (NET) is a structured mind-body technique developed by chiropractor Dr. Scott Walker. It’s built on a simple observation: the body can keep reacting to an old stressful experience as if it’s still happening. Your heart rate jumps, your muscles tighten, your digestion shifts, even when the event is long over.

NET is designed to find those stuck stress patterns and help the body let go of them. Researchers at Thomas Jefferson University described it as a brief, targeted approach that “combines traditional desensitization principles with complementary modalities.” In practice, that means a session pairs the recall of a specific stressful memory or feeling with a gentle physical correction, so the nervous system can respond differently the next time.

The Thomas Jefferson University research

The most significant NET research comes from the Jefferson-Myrna Brind Center of Integrative Medicine at Thomas Jefferson University in Philadelphia. The work was led by Daniel A. Monti, M.D., a psychiatrist and integrative medicine researcher, and published in the peer-reviewed Journal of Cancer Survivorship.

The research focused on a specific, common problem: cancer survivors who keep experiencing traumatic stress symptoms, such as intrusive memories, anxiety and avoidance, long after their diagnosis or treatment.

The first pilot study (2007)

Seven women with cancer-related traumatic stress each received three NET sessions. The researchers measured how distressed they felt and how their bodies reacted (heart rate and skin conductance, two signs of the body’s stress response). All four measures improved significantly after treatment. The authors were clear that this was a small pilot without a comparison group, and called for more research. That’s exactly what came next.

The brain imaging study (2017)

This time, 23 cancer survivors were randomly assigned either to receive NET or to wait. Before and after, each person lay in an fMRI scanner and listened to a recording describing their own distressing memory.

Before treatment, brain regions linked to traumatic memory and distress lit up strongly. After NET, activity in several of those regions (the parahippocampus, brainstem, anterior cingulate and insula) was significantly reduced when participants heard their memory again. The NET group also showed significant drops in distress, anxiety and traumatic stress symptoms compared to the group that waited.

In public comments on the findings, Dr. Monti noted that after just four to five brief sessions, the way patients’ brains reacted to stress cues had normalized. The published paper describes the results as preliminary and an initial step toward understanding how NET works.

The follow-up analysis (2018)

A follow-up paper looked deeper at the same data and found changes in how the cerebellum communicated with the amygdala and prefrontal cortex, areas involved in emotional memory and regulation. Those changes were associated with a calmer autonomic (automatic stress) response to the distressing memory.

What this means for you

In plain language: when people revisited a painful memory after NET, both their brains and their bodies reacted less. The memory was still there. The alarm response attached to it was quieter.

Other published NET research

Chronic low back pain (2022). A randomized, double-blinded, placebo-controlled trial of 112 patients with chronic low back pain, published in the Journal of Integrative Medicine, compared eight NET sessions to a placebo treatment. The NET group showed significant reductions in pain, disability and several blood markers of inflammation, along with better quality-of-life scores, with results measured out to six months.

Hypothyroidism (2015). A randomized, placebo-controlled trial of 90 adults with hypothyroidism found that NET was safe but did not improve thyroid outcomes compared to placebo. I include this on purpose. Honest science includes the results that didn’t pan out, and it helps show where NET fits and where it doesn’t.

How NET might work (2026). A recent review in the journal Cureus proposed that NET may work through memory reconsolidation, the brain’s natural process of updating an emotional memory when it’s recalled under new conditions. This is a proposed explanation, not a proven one, but it connects NET to a well-studied area of neuroscience.

What the research doesn’t show (yet)

I’d rather you hear this from me than discover it later:

1. Most NET studies are small. The findings are promising, but they need to be repeated in larger groups by independent research teams.
2. Some NET research, including the first Jefferson study, was supported by the ONE Research Foundation, the nonprofit that supports NET research.
3. The Jefferson studies looked at stress symptoms in cancer survivors. They did not study NET as a treatment for cancer itself, and NET is not a cancer treatment.
4. NET is not a replacement for medical or psychological care. Many of my clients use NET alongside their physicians and therapists.
