IEMT and EMDR — what is the difference?

The question

Both use eye movements — but they are not the same

It is one of the first questions I get: “You work with eye movements? Isn’t that just EMDR?” It is a logical question — both methods do indeed use eye movements, and that stands out. But that is largely where the similarity ends.

EMDR and IEMT emerged in different places, in different worlds and for different questions. They resemble each other on the surface in the way that two doors can look alike while leading to very different rooms. Below I explain what distinguishes them — honestly, and without placing one above the other.

‘Two methods that look similar on the surface but are built for different questions.’

What EMDR is

A clinical trauma treatment

EMDR stands for Eye Movement Desensitization and Reprocessing and was developed in the 1980s by American psychologist Francine Shapiro. It emerged from mental health care and is used primarily as a treatment for trauma — think of significant events that still carry a deep charge.

EMDR is usually delivered by psychologists, psychotherapists and other healthcare practitioners within clinical settings, often following a fixed protocol. It has been thoroughly researched and holds an established place in the treatment of conditions such as post-traumatic stress. With EMDR, it is typically necessary to focus on the memory itself and what it does to you.

In short: EMDR is a serious, clinical treatment for complaints that require treatment. That is exactly where it belongs.

What IEMT is

A short coaching intervention

IEMT — Integral Eye Movement Technique — emerged later, around 2005, developed by Andrew T. Austin from a background in coaching, hypnosis and NLP. It is not a clinical treatment but a coaching intervention: a calm, focused way of working within coaching with a recurring response or a pattern that thinking alone cannot shift.

Two things make it different from EMDR. First: you don’t need to share your story. We work on how a response or feeling arises now, not on the details of what happened then. Second: it is designed as a short course — usually a handful of sessions of sixty to ninety minutes, not a lengthy treatment.

You don’t need to tell or relive the content of a memory to work with IEMT.

Those who want to know what such a session feels like from the inside can read about it on how a session feels.

Side by side

Not better — different

It is tempting to say that one is ‘better’ than the other, but that is not correct and I deliberately do not make that claim. They are two different instruments for two different kinds of questions.

If you are dealing with a trauma or complaints that require treatment, EMDR — or another recognised treatment within healthcare — takes precedence. That is what it is designed for, and that is where it belongs. If a pattern or response keeps recurring, often precisely when you have already understood it, and you are looking for a calm, short way in? Then IEMT may be a good fit.

IEMT does not replace therapy or medical treatment. For clinical or acute complaints I refer you to the appropriate care — more on this at what IEMT is not.

What the research found

The first time they were compared directly

In 2026, Maastricht University published the first independent research to compare IEMT and EMDR directly. The brief finding: on reducing emotional charge, both methods performed comparably, with the effect retained at a follow-up measurement one week later. No winner — an equal result on the primary measure.

Something else stood out. When participants — still blinded — were asked which experience they had found most comfortable, a majority chose the IEMT condition. The two most commonly cited reasons: you don’t need to share the content of the memory, and there were fewer physical after-effects such as headaches or tired eyes.

Those last two reasons are not minor details. For many people who have been carrying a theme for a long time, they are precisely the thresholds that kept them from addressing it sooner: no desire to explain it yet again, and the wish to be able to simply carry on afterwards.

To be honest about what this means: it was a first, small-scale and non-clinical study. Not miracle-cure evidence — but a serious first signal. The full picture of what it does and doesn’t show is on what the science says.
