Evidence reviewed: October 2026
Shaking releases trauma stored in muscles and resets the nervous system.
Gentle movement may help some people feel calmer or more connected to their body. Evidence does not establish that shaking literally expels stored trauma or reliably treats PTSD. Subjective relief deserves respect without assuming a proven mechanism.
Why has this claim become popular?
Trauma can involve powerful physical sensations, and a body-focused practice can feel more accessible than talking. Somatic shaking includes informal exercises and structured approaches such as Trauma Releasing Exercises (TRE). These are not all the same intervention, and personal experiences need not be dismissed to question the explanation attached to them.
What does the scientific research show?
Body-focused treatments are a broader evidence category
Van de Kamp and colleagues’ 2023 meta-analysis included 29 comparative studies of body- and movement-oriented interventions for PTSD. The pooled symptom effect was moderate, but highly heterogeneous. The review combined diverse approaches, so it cannot isolate shaking or prove a ‘stored trauma release’ mechanism. Changes in arousal, movement, therapeutic support or attention to bodily sensations could contribute to relief. Evidence for a broad category cannot be assigned unchanged to a specific viral exercise.
The latest TRE review still finds major research gaps
Roos, van Niekerk and Tönsing’s September 2026 scoping review mapped 22 studies represented by 24 records. It reported promising signals in stress- and trauma-exposed populations, including mood and anxiety-related sleep difficulties. Designs were not consistently rigorous. A scoping review describes a literature; it is not proof from a set of high-quality blinded trials. It does not establish literal expulsion of trauma, nor equivalence to established PTSD treatment.
Limitations and uncertainty
Trauma affects memory, threat responses and bodily experience. ‘Stored in the body’ can be a meaningful metaphor, but it should not be treated as a measured substance that shaking removes. Small samples, diverse protocols, non-randomised work and expectation effects leave uncertainty about benefits and harms. Comparative research needs a suitable control, validated symptom measures, longer follow-up and reporting of worsening symptoms. Apparent calm after one session is not necessarily remission of a trauma disorder.
This judgement concerns an intervention claim, not whether someone’s distress or relief is real.
Do the hips store trauma?
The same distinction applies to hip-opening or stretching claims. Relief, emotion or a change in muscular tension can feel real without demonstrating that emotional memories were literally stored in hip muscles and released. This interpretation follows the evidence limits discussed above; a meaningful personal experience does not establish the proposed storage mechanism.
What does this mean for you?
If gentle movement feels helpful, you need not force shaking or chase a dramatic release. Stop when it causes dizziness, pain, panic, dissociation or distress. A trauma-informed practitioner can help adapt a practice and recognise when it is unsuitable. Persistent flashbacks, avoidance or hyperarousal deserve professional support. NICE recommends trauma-focused CBT and, in appropriate circumstances, EMDR delivered by trained practitioners; these are more established options.
Body-focused exercises may be an adjunct, chosen with consent and control, rather than a substitute or a test of whether you are healing correctly.
For another regulation claim, our investigation of vagus-nerve exercises distinguishes a plausible calming response from evidence of a complete nervous-system reset.
The Evidence vs Hype verdict
A compassionate distinction is possible: a practice may feel relieving while its literal trauma-release explanation remains unproven. More rigorous research is needed before shaking can be presented as a dependable trauma treatment.
