What Researchers Did
Researchers conducted an open-label randomised controlled trial involving 146 Egyptian children with autism spectrum disorder to evaluate hyperbaric oxygen therapy, Tomatis sound therapy, or a combination of both.
What They Found
The combination of Tomatis sound therapy and hyperbaric oxygen therapy significantly improved autism symptoms more than either therapy alone. The CARS score for the combination group decreased from 49.34 ± 17.54 before intervention to 35.04 ± 13.38 after therapy (p < 0.001).
Canadian Relevance
This study was conducted in an Egyptian cohort and has no direct Canadian connection.
Study Limitations
The study acknowledges that evidence for combination therapy in ASD remains controversial and suggests future research needs more sophisticated designs and consistent baseline measures.
