Laser Acupuncture Effects on Speech and Social Interaction in Patients with Autism Spectrum Disorder

Objective: Disorders of speech ability and social interaction are the most-common symptoms in children with autism spectrum disorder (ASD). Acupuncture, as an adjunctive therapy, is known to help improve speech ability and social interaction in children with this condition. One of the acupuncture modalities with minimal side-effects, and that is safe for children, is laser acupuncture or laserpuncture. This study's aim was to determine laserpuncture's effects on speech ability and social interactions in patients with ASD. Materials and Methods: This randomized, double-blinded clinical trial involved 46 patients in 2 groups. All respondents qualified, and none dropped out. The treatment group (n = 23) received sensory-occupational integrative therapy and verum laserpuncture therapy and the control group (n = 23) received sensory-occupational integrative therapy and placebo laserpuncture. The groups' speech ability and social interaction were evaluated with a WeeFIM® questionnaire; parental reports were collected, using sensory profiles before and after treatment. Results: There were improvements in speech ability and social interaction in the verum laserpuncture group more than in the placebo group after treatment. Perception score was P < 0.001; odds ratio (OR): 18.8; 95% confidence interval (CI): 4.09-87.17. Expression score was P < 0.001; OR: 50.2; 95% CI: 5.61-450.2. Social interaction score was P = 0.005; OR:7.2; 95% CI: 1.68-31.42. Parental report score was P = 0.765. Conclusions: Verum laserpuncture in this clinical trial improved speech ability and social interaction scores more effectively than placebo laserpuncture did in patients with ASD.
