In brief
Stimming (from "self-stimulation") means repeated, often rhythmic movements or sounds, for example hand flapping, rocking, finger snapping or humming. In assessment, "stereotyped or repetitive movements" count as a possible feature of autism; many adults on the autism spectrum call them "stimming". [2] In a British interview study, adults described stimming as a help with self-regulation in sensory overload, distressing thoughts and strong feelings, and many rejected treatments meant to remove it. [2] The 2021 guideline did not apply its recommendations to every repetitive behaviour but to disruptive behaviour. [4, Rec. 23] Methods involving punishment or coercion should never be used. [4, Rec. 30]

Status of the guideline: This article uses the S3 guideline on therapy (2021). It expired on 23.03.2026. [1] The statements are not automatically wrong, but they are not backed by a valid guideline.
What stimming is
In the interview study, participants described stimming as repeated, mostly rhythmic behaviour expressed through body movements (hand flapping, finger snapping, hair pulling, rocking, spinning) and also through sounds (murmuring, humming, singing). Many experienced it as involuntary, at least at first; some could also use it deliberately to prevent being overwhelmed. [2] As a feature of autism, it is listed among the repetitive patterns of behaviour: Routines, repetitive behaviour and special interests.
What stimming can be for
The study (31 to 32 adults on the autism spectrum in England, depending on the figure in the text) found two main themes. The first theme: stimming as self-regulation. Participants attributed it to overwhelming environments, sensory overload, distressing thoughts (“noisy thoughts”) and overwhelming feelings; most described it as pleasant or calming. It could regulate positive as well as negative feelings (excitement, anxiety), and certain movements could also signal feelings. Nobody described too little stimulation as a trigger. [2] More on stimuli: Recognising and preventing sensory overload.
Stigma and hiding
The second theme: stimming is often devalued. Participants experienced anger, shame and confusion when others asked them to stop, and suppressed stimming in public, turned it into more socially accepted forms or only stimmed alone or with people they trust. Many reported that it became less accepted with increasing age. Acceptance grew through understanding, for example when family or colleagues knew the reason. [2] A small interview study with four young adults who as children received therapies to “fix” repeated behaviours described doubt, stigma and the feeling of being “repaired” by other people’s standards, and later an acceptance of their own authenticity. [3] More: Masking: when adapting is exhausting.
When stimming causes harm
Participants also described forms of stimming that physically harmed them (for example rubbing fingers sore when anxious) and that they did not find helpful, or that disturbed or hurt others without their noticing. The study did not describe deliberate self-injury. [2] In the case of injuries, or if stimming is very distressing, a medical or therapeutic assessment makes sense; note: this is an assessment by the editorial team.

What the 2021 guideline said
The guideline treated repetitive behaviour, particular interests and special reactions to stimuli as a target symptom of its own. Its recommendations related to disruptive repetitive behaviour that burdens everyday life. For preschool children, it named, among other things, guidance of parents by behavioural therapists on structuring daily life, “extinction by ignoring” and building alternative behaviours. [4, Rec. 23] At the same time, it stated that methods involving direct punishment or coercive measures should never be used, [4, Rec. 30] and reported the view of a self-advocacy association that exposure sometimes only leads to an exhausting habituation to enduring. [4, Rec. 27] The guideline has expired. [1]
What do we know – what is still open?
Finding (qualitative studies, personal accounts): Adults on the spectrum mostly experience stimming as helpful for self-regulation and experience stigma. [2]
Expert consensus/guideline: Treatment only for disruptive behaviour; no punishment or coercion. [4, Rec. 23, 30]
Open:
- How often stimming is experienced as helpful or harmful is not shown by the studies (small, non-representative samples; no systematic data on level of functioning and diagnosis). [2]
- Experiences of people with high support needs or without spoken language are hardly represented in the studies read; the participants spoke in interviews or focus groups.
- How different ways of responding (accepting, redirecting, treating) have effects in the long term has not been studied, as far as we could read.
What else you should know
- If you observe yourself: Stimming is not “wrong”. Whether and how you show it is your decision; in your surroundings, education helps, as the interview participants reported. [2]
- If it concerns your child: First ask what it is for and what happens beforehand (behavioural analysis), rather than stopping it straight away. This is a suggestion by the editorial team and follows the guideline’s idea of clarifying causes first. [4, Rec. 61]
