Does somatic therapy work?

People talk about somatic therapy in two registers. In one, it’s the thing that finally worked after everything else failed. In the other, it’s unevidenced and slightly embarrassing. Neither is right, and getting to the accurate version means first dealing with the phrase that keeps getting used to end the argument.

What “evidence-based” actually means

It sounds like it means proven. It doesn’t. It means a treatment has been manualised, run through randomised controlled trials, and shown to beat whatever it was compared against. Those are useful facts. They’re narrower than the phrase implies, and the psychologist Jonathan Shedler has spent years laying out exactly how much narrower.

Start with who’s in the trials. To get a clean signal, studies screen out complexity — active substance use, suicidality, dissociation, more than one diagnosis at a time. What’s left is a patient who barely exists in a real waiting room. If you’ve PTSD and also drink too much, which is extremely common, you were probably ineligible for the studies now being used to tell you what to do.

Then there’s who leaves. Trauma-focused protocols ask people to go toward the worst thing that ever happened to them, on a schedule. A lot of people can’t, and dropout in exposure trials runs high. When results get reported for the people who finished, the ones who found it intolerable quietly vanish from the arithmetic. They didn’t fail the treatment. The number just stopped counting them.

And then there’s what it beat. Shedler’s sharpest point is about comparison conditions — he describes some of them bluntly as shams, treatments designed to lose. Graduate students delivering the rival therapy against seasoned clinicians delivering the favoured one. Psychodynamic therapists instructed not to discuss the trauma. Beating that isn’t the same as being better.

Add publication bias, fixed session counts nobody uses in practice, and outcomes measured as symptom-scale movement rather than a life that changed, and “hundreds of trials” turns out to describe a literature, not a verdict.

So what about the somatic research

Somatic Experiencing has the most trial evidence of the body-based approaches, and it is worth being exact about how much. The main randomised controlled trial, Brom and colleagues in 2017, had 63 people with PTSD: 33 got fifteen weekly SE sessions, 30 waited. The SE group improved. A second trial looked at brief SE for chronic low back pain with PTSD symptoms alongside it. That is real evidence and it is two studies, not a field. Waitlist is also a low bar — the same low bar much of the CBT literature cleared.

Sensorimotor psychotherapy and Hakomi have less, and a good deal of what exists is uncontrolled, small, or run by people with a stake in the result. That doesn’t make them worthless. It makes them preliminary, which is a different claim, and one you should hold against them honestly.

The science next door is sturdier than the therapy science. That trauma has physical correlates, that interoception varies and can change, that your autonomic state shapes what you’re able to think about — that holds up. The shaky leap is from there to any particular protocol being the answer.

What that means for you

Not “so it’s all equally unproven, pick whatever.” That would be its own kind of dishonesty. Trauma-focused CBT and EMDR have helped an enormous number of people, and if you haven’t tried a structured trauma treatment, one of them is a completely reasonable place to start.

What it does mean is that being told to do exposure first because it’s evidence-based, when you already tried it and couldn’t stay in the room, is bad advice dressed as science. You’re not a treatment failure. You may be the kind of person the studies excluded.

And if your trouble is the between-the-cracks kind — chronic bracing, feeling absent from your own life, a body that reacts to things you made peace with a decade ago — the manualised protocols weren’t built for that. The somatic literature is thinner, and it’s at least aiming at the right target.

Claims worth doubting, on this side of the fence

That trauma is stored in specific tissues in a literal way. That one session can release what you’ve carried for decades. That the body can’t lie. That any of this replaces psychiatric care for a serious condition. These get said with great confidence, and confidence isn’t evidence — which is the whole point of this page, and it cuts both ways.

Be especially wary of anyone who explains why their approach can’t be studied. Plenty of hard-to-measure things have been measured. It’s a convenient argument, and it should raise your eyebrows rather than your hopes.

A fair summary

Somatic therapy is promising, partly evidenced, and oversold by some of its advocates. The treatments it gets unfavourably compared to are better evidenced than it is, and also less conclusively so than the phrase “evidence-based” suggests. Try what fits your situation with a properly trained practitioner, give it six to eight sessions, and judge it on whether anything outside the room has moved.
