This quasi-experimental study investigated effects of Tai Chi Chuan training on stereotypic behavior of children with autism spectrum disorder. Twenty-three participants (mean age = 9.60 ± 1.40 years) were assigned to experimental (N = 12) and control (N = 11) groups.
The experimental group received 12 weeks of Tai Chi training and all participants had pre, post, and one-month follow-up assessments. Stereotypic behavior measured using Gilliam Autism Rating Scale 2 Scores, was significantly altered by ~ 25% in the Tai Chi Chuan group.
Behavioural change was maintained at follow up since there was no significant difference between that and the posttest.
In conclusion, Tai Chi Chuan training is a useful and appropriate intervention to modulate behavior in individuals with autism spectrum disorder.
