Within the bodily world, Tracy was about midway via a telehealth remedy session. Her eyes have been closed and her arms have been crossed over her chest, her fingers rhythmically tapping alternating shoulders: left-right-left-right. However in her thoughts, she was in her outdated basement, hiding from her ex as he screamed obscenities at her from the ground above. She stored tapping. After a few minute, the voice of her new therapist broke in from her laptop computer, asking, “What are you noticing?”
Worry, principally. Within the basement, she’d felt frozen with terror, satisfied that this time, her ex’s anger would flip violent. The reminiscence had recently been torturing Tracy, who’s in her early 40s and lives in Kansas Metropolis, Missouri, the place she is a licensed skilled counselor. (Therapists want remedy, too.) The reminiscence would pop into her mind at random, sending her into debilitating panic assaults on a weekly foundation. Now, together with her personal therapist, she was recalling the second on objective. Three extra occasions, for a few minute at a time, Tracy’s therapist directed her to carry the reminiscence in thoughts whereas tapping her shoulders. “ that factor the place you utilize one hand to faucet on the highest of your head and the opposite to rub your abdomen?” she requested me. “It appears like speaking and doing that on the identical time.” Two or three classes later, it was the strangest factor: The basement reminiscence — as soon as so emotionally charged — felt slightly bit duller. She began having fewer panic assaults, too.
EMDR, as Eye Motion Desensitization and Reprocessing is colloquially known as, has been round for 4 a long time however solely considerably not too long ago grow to be a mainstream therapy possibility. An evaluation from the web health-care platform Zocdoc discovered that its customers booked 79 p.c extra EMDR appointments in 2025 in comparison with the earlier 12 months. It has newfound cultural cache too: Within the newest season of The Secret Lives of Mormon Wives, Mikayla Matthews sees an EMDR therapist to cope with the sexual abuse she skilled as a baby. (The therapist holds up her pointer and center fingers and waves them left to proper as Matthews follows together with her eyes. The motion appears to unlock one thing in Matthews, and she or he begins to cry as she describes deep emotions of guilt.) In 2024’s Babygirl, EMDR makes a quick cameo — alongside Botox and cryotherapy — as one among many self-care therapies undertaken by Nicole Kidman’s character, Romy, a tech CEO. And final summer season, Miley Cyrus credited the remedy with altering her life. “It sounds so trippy, however that is medical,” Cyrus informed the New York Instances. “That is actual.”
Plenty of main medical associations are in settlement with Cyrus, not less than in the case of post-traumatic stress dysfunction. Within the 2010s, the World Well being Group acknowledged EMDR in its medical tips for the therapy of PTSD, and the U.S. Veterans Affairs Division and the American Psychological Affiliation additionally named the remedy as an efficient trauma-treatment technique. Greater than 30 randomized managed trials have proven it to be an efficient therapy, with about the identical success fee as different therapeutic methods, like cognitive behavioral remedy, in lowering PTSD signs. What’s stunning, although, is that many therapists don’t perceive why it really works — and amongst those that do perceive the scientific theories that underscore it, there’s critical doubt as as to if the theories really make sense.
EMDR’s origin story is considerably uncommon: On a sunny spring day in 1987, a psychology pupil named Francine Shapiro went exterior for a stroll, mulling a private drawback as she strolled round a lake. After some time, her worries quieted down. “The odd factor was that my nagging thought had disappeared. By itself,” she wrote in her 1995 e book, EMDR: The Breakthrough Remedy for Overcoming Anxiousness, Stress, and Trauma. “After I introduced it again to thoughts, I discovered that its unfavorable emotional cost was gone.” Contemporary air and train are likely to have that impact on folks. However throughout her stroll, Shapiro seen she was transferring her eyes backwards and forwards as she thought via her drawback. Might these eye actions clarify her lighter temper?
It wasn’t essentially the most intuitive conclusion. However Shapiro took it and ran with it, designing research and refining the therapy till she and others ultimately developed a neurobiological concept across the side-to-side eye actions, which ultimately grew to become referred to as “bilateral stimulation” — sensory experiences that alternate between the left and proper sides of the physique, thus partaking either side of the mind. Bilateral stimulation can contain transferring the eyes backwards and forwards, however it could actually additionally incorporate auditory cues in alternating ears or bodily touches corresponding to shoulder tapping. One long-held concept proposes that bilateral stimulation might mimic REM sleep, which is believed to play an element in reminiscence storage. “Most individuals have had the expertise of entering into an argument together with your finest buddy, and also you went to sleep and also you awoke the subsequent day and it felt higher,” mentioned Wendy Byrd, board president for EMDRIA, a nonprofit that gives coaching and certification in EMDR for therapists. “The mind pruned and moved data round and saved it in a special place in order that it’s not so energetic. That’s what EMDR does.”
One other clarification for the way and why EMDR works — probably, a greater one, argue some researchers — is the working reminiscence mannequin, which is predicated in psychology, not neurobiology, mentioned Advert de Jongh, emeritus professor of hysteria and habits problems on the College of Amsterdam. This concept is pleasingly intuitive: It’s laborious to do two issues without delay, as anybody who’s ever tried to carry a considerate dialog with their companion whereas additionally answering work emails can attest. “In EMDR, we convey up a traumatic reminiscence to our working reminiscence — after which if we do one other activity on the identical time, these duties begin to compete with one another,” says Suzy Matthijssen, a researcher and medical psychologist within the Netherlands. With out your full deal with the reminiscence, its depth diminishes.
In accordance with this concept, the sensory duties related to bilateral stimulation, or BLS because it’s generally nicknamed, are efficient not as a result of they interact either side of the mind, however as a result of they tax the working reminiscence, says Matthijssen. In different phrases, she informed me: “BLS is b.s.” Matthijssen and de Jongh are presently creating a remedy known as EMDR 2.0, which de-emphasizes the usage of bilateral stimulation in favor of working-memory taxation. With EMDR 2.0, purchasers is likely to be requested to spell a phrase backward whereas holding their disturbing reminiscence in thoughts. Or Matthijssen would possibly make them do math issues or stroll across the room in a particular (and intentionally complicated) sample. “EMDR is a implausible remedy,” she informed me. “The one factor I’m actually attempting to unravel is that magical perception in bilateral stimulation.”
However many researchers I spoke to informed me that with BLS or not, EMDR is just not properly understood. Within the late Nineteen Nineties, Richard McNally, a professor of psychology at Harvard, in contrast the remedy to mesmerism, a Nineteenth-century therapeutic craze by which the practitioner would place magnets across the affected person’s physique in an effort to encourage the motion of an invisible therapeutic fluid. Likewise, College of Washington psychologist Gerald M. Rosen has been writing critically about EMDR because the Nineteen Nineties (one paper written with McNally and others argued that EMDR’s “theoretical clarification approaches the bounds of neurobabble”) and nonetheless refuses to let the difficulty drop, publishing his newest critique in 2024. He has one other within the works. “I appreciated what was creating and noticed via the claims from the beginning,” Rosen informed me of his decades-long campaign. McNally, although, modified his thoughts after listening to in regards to the working-memory taxation concept. He quoted the economist John Maynard Keynes: “‘When the details change, I alter my thoughts.’”
Delivering efficient remedy is tough, and for some, what is likely to be making it tougher is a niche between scientific understanding and medical observe. Many therapists informed me that the EMDR coaching they obtained emphasised the neuroscientific element of the remedy, one thing a lot of them weren’t skilled to completely grasp. “You see it on a regular basis,” de Jongh, the Dutch psychologist, informed me. “You go to conferences, and a presenter reveals you photos of the mind — everyone seems to be it going, Oh my gosh!” Measurable adjustments within the mind appear extra goal and convincing than sufferers’ personal reviews of their experiences, he defined. In 2024, de Jongh printed a paper outlining the “state of the science” of EMDR. In his opinion, the strongest scientific assist for EMDR is psychological, not neurobiological.
At first, Angela Nauss, a licensed marriage and household therapist in Colorado, was drawn to the neuroscience related to the remedy. In 2017, she was a brand-new therapist nonetheless working beneath supervision at a Southern California drug and alcohol rehab facility. She usually felt sick ready to deal with the enormity of her purchasers’ mental-health wants, and her supervisor was normally too busy to reply her questions. (She as soon as requested methods to finest deal with bipolar dysfunction. “Google it,” got here the reply.) EMDR’s detailed protocol, together with the invocation of neuroscience, was immediately interesting. “I used to be like, Lastly, I do know what I’m speculated to do in session,” she informed me. “All I needed was to really feel like remedy truly does one thing, as a result of I used to be working within the trenches.”
Nauss got here to understand EMDR a lot that she determined she needed to current about its transformative energy at a psychotherapy convention. However because the convention deadline approached, she discovered that a few of her purchasers — those that had initially improved with the remedy — had regressed. Finally, she paid $4,000 for a second spherical of EMDR coaching. In the meantime, she stored researching EMDR for her proposed presentation. The extra she regarded into it, the extra her sense of certainty across the therapy diminished. Finally, her analysis developed right into a essential article printed in The Therapist in 2022. Within the article, she asserts that the neuroscientific proof explaining EMDR’s efficacy is weak — and that almost all therapists don’t realistically grasp the science, anyway. “When you ask three completely different EMDR counselors to clarify how EMDR works, they may possible provide you with three completely different solutions,” she wrote, “probably as a result of EMDR analysis is dense and obscure with out ample coaching in neuroscience.”
Whereas researching her article, Nauss found that a lot of her colleagues had altered the EMDR protocol to go well with their very own preferences, generally incorporating the remedy with different modalities. Freestyling isn’t one thing Byrd, the EMDRIA board president, encourages, nor would most EMDR researchers. “I don’t know what would occur,” Byrd informed me, “however you couldn’t say that you simply have been doing EMDR, as a result of that’s not what EMDR is.” However a number of EMDR-trained therapists informed me they’ve custom-made the therapy anyway.
Tracy, the Kansas Metropolis therapist whose traumatic recollections of her ex-boyfriend misplaced most of their energy after 5 EMDR classes, is one among them. (She nonetheless has panic assaults generally, however she’s in a position to calm herself down earlier than they spiral uncontrolled.) She delivers her personal model of EMDR to her sufferers: “I type of slice EMDR up into items,” she informed me. She doesn’t at all times observe the steps so as, for instance. However utilizing EMDR “buzzers” (handheld paddles that vibrate to provide a tactile model of bilateral stimulation) actually does appear to assist regular her purchasers, particularly those that are likely to really feel their feelings bodily. “It seems to be just a bit little bit of set dressing,” she mentioned, “and if some favor that, nice.”
She has a concept as to why EMDR labored so properly on her, and it has little to do with neuroscience. Tracy doesn’t like to sit down nonetheless when she’s upset. On a nasty day, she informed me, she’d reasonably get out her stitching machine and begin an elaborate new crafting undertaking than lie on the sofa and watch TV. She thinks the shoulder tapping might have appeased the same impulse. “I don’t assume lots of fancy shit’s occurring in my mind,” she mentioned. “I feel it simply gave me one thing to do.” That’s how she explains EMDR to her purchasers, too. “So long as the therapist is purchased in and the purchasers are purchased in, does it matter if you happen to say, ‘I would like you to put on purple sneakers with jingle bells on them?’” Tracy went on. “If that finally ends up having some optimistic impact, and nobody was harmed — does it matter?”
McNally identified that scientists don’t agree on why SSRIs work, both. “However they can assist folks,” he mentioned. And so can EMDR, he added. On the identical time, there’s no query that understanding why a therapeutic approach works is preferable. “If we all know why it really works, we are able to additionally make our therapies higher, as a result of then we all know the place and when to tweak,” Matthijssen defined.
However does a consumer have to know that? Does a therapist? Is it the therapy technique that makes the distinction, or is the catalyst extra ineffable, like the connection between the therapist and the consumer and their mutual perception within the therapy, that predicts whether or not remedy can be efficient? In 2019, one psychologist argued that this debate is inappropriate: Each are essential. A long time’ price of analysis stresses the significance of the “therapeutic alliance,” or the concept that the therapist and consumer will need to have a very good relationship and agree on each the objectives of their work collectively and the strategies they’ll use to fulfill them. “You need to discover any person whose way of living matches the identical form of ethos that you’ve got,” Tracy mentioned. “That’s a part of the therapeutic magic.”
