In a study by UC Irvine
neurobiologists, children with autism showed significant improvement
after six months of simple sensory exercises at home using everyday
items such as scents, spoons and sponges.
They found that a
treatment known as environmental enrichment led to notable gains in male
subjects between the ages of 3 and 12.
Study co-authors Cynthia Woo and Michael Leon randomly assigned 28 boys to one of two groups, balanced for age and autism severity. For half a year, all subjects participated in standard autism therapies, but those in one group also had daily sensory enrichment exercises.
Parents of these children were given a kit containing household products to increase environmental stimulation, including essential-oil fragrances such as apple, lavender, lemon and vanilla. The boys smelled four of these scents a day and listened to classical music each evening.

Parents of these children were given a kit containing household products to increase environmental stimulation, including essential-oil fragrances such as apple, lavender, lemon and vanilla. The boys smelled four of these scents a day and listened to classical music each evening.
In addition, the parents
conducted twice-daily sessions of four to seven exercises with their
children involving different combinations of sensory stimuli - touch,
temperature, sight and movement among them. Each session took 15 to 30
minutes to complete.
After six months of therapy, 42 percent of the children in the enrichment group showed significant improvement in behaviors commonly affected by autism - such as relating to people, having typical emotional responses and listening - compared with 7 percent in the standard-care group.
They also scored higher in cognitive function, whereas average scores for the boys in the standard-care group decreased. Moreover, 69 percent of parents in the enrichment group reported improvement, compared with 31 percent of parents in the standard-care group.
"Because parents can give their child sensory enrichment using items typically available in their home, this therapy provides a low-cost option for enhancing their child`s progress," said Woo, an assistant project scientist in neurobiology and behavior.
The researchers noted that most current therapies for autism must be started at a very young age to be successful, while the average age in this study was 6.6.
"We believe that sensory enrichment can be an effective therapy for the treatment of autism, particularly among children past the toddler stage," said Leon, a professor of neurobiology and behavior affiliated with UC Irvine `s Center for Autism Research and Treatment.
"At the same time, we need to know whether we can optimize the treatment, whether there are subgroups of children for whom it`s more effective, whether the therapy works for older or younger children, and whether it can be effective on its own," he added.
He and Woo are now conducting a second, larger randomized clinical trial that includes girls.
Results of the study appeared online in Behavioral Neuroscience.
