Movement of the body is an essential way to characterise autism, according to diagnostic criteria. However, qualifying descriptions of what autistic movements are, their functions and personal value, are missing from academic literature and clinical guidance. We systematically searched for autistic adults’ descriptions of their body and its movement within autobiographical narratives in blog data. Descriptions from 23 autistic authors formed a qualitative data set. The search strategy identified descriptions of movements and meanings without a priori definitions, such as being stereotyped or ritualistic, which were submitted to a thematic analysis. Authors described stigmatisation of some of their movements, causing censorship. However, movement provided personal benefits, including enhanced thinking and focus, routine, sensory regulation, release of energy, increased body connection and awareness, regulated emotion, and time without self-restraint. Examples included stimming or self-stimulating behaviour, dancing, and physical exercise. Movement was accompanied by qualifying descriptions of being natural and harmless. Moving freely, expressively, and sometimes repetitively, strengthened self-identity. In conclusion, body movements have both stigmatised and non-stigmatised appearances for autistic adults, but these cannot be distinguished by the function of the movement. Expressive, regulating and repetitive movements can be a well-being resource for autistic people. Implications for practice are discussed. Lay abstract What is already known? Moving the body in ‘stereotyped’, ‘repetitive’, ‘ritualised’ or ‘unusual’ ways is part of the criteria for receiving a diagnosis of autism. However, the reasons for these movements and their personal value are not well understood. Certain ways of moving have become part of a disorder, and have received negative judgements, whereas other movements have not. What this paper adds? We searched online blogs for descriptions of movement written by autistic adults, using their preferred language and definitions. The blog authors said that many types of movement attracted negative judgement, including mis-coordination shown during sports, dancing in unusual places or moving repetitively, such as when stimming. However, movement provided personal benefits, and could enhance thinking and focus, provide meaningful routine, contribute to sensory regulation, release energy, increase body awareness, emotion regulation and strengthen self-identity. Implications for practice and policy Movement could be a well-being resource, used to reduce distraction, overwhelm, confusion and distress for autistic people. This should be considered within personal coping strategies and psychological therapies. The examples provided in this study could inform autism assessments, to ensure that the meanings of movements are considered alongside the appearances of movement. Some movements such as stimming have the same functions as many other ways of moving, including dancing and exercising, which could help to reduce stigma around being autistic if reflected in policy and practice. Improving understanding is important for informing how autism is assessed, and how personal experiences of being autistic are heard.
