Why do kids with autism stim? Links to anxiety and sensory processing

What is stimming?

Stimming is an everyday term for self-stimulatory behavior and usually involves repetitive motions or sounds that are done in a regulated manner but do not appear to fulfill any visible purpose.

We all stim occasionally. It’s normal. Maybe you twirl your hair, tap your feet or crack your knuckles. The term ‘stimming,’ however, generally refers to the more intense and more frequent repetitive behaviors displayed by individuals with developmental disabilities, including autism.

For example, a boy with autism may flap his hands, rock back and forth, spin objects, or pace around. He may also stim vocally (also called verbal or oral stims). These behaviors include mumbling to himself, spitting, groaning, screeching, and repeating the same phrase over and over. In some extreme situations, repetitive behaviors may lead to self-harm, such as when a person hits his or her head against a hard surface (referred to as head banging) or bites him or herself. People with autism may also perseverate or fixate on certain things like a light, a word, a texture or a video.

Stimming linked to anxiety

The familiar, repetitive motion of stimming can be soothing. Dr. Temple Grandin explains that she stimmed to calm herself.3 She notes,

“It may counteract an overwhelming sensory environment, or alleviate the high levels of internal anxiety these kids typically feel every day.”

Stimming can be a way of relieving pressure. Think of it like the steam valve of a pressure cooker that helps to maintain the optimum pressure inside by releasing some of the steam when necessary. If you hit your thumb with a hammer, do you shake it? The shaking motion helps distract you from the pain.

A 2012 study on the relationship between anxiety and repetitive behaviors in children with autism showed that those with higher levels of anxiety also displayed more stimming behaviors.2

Anxiety in autism linked to sensory processing

In many people with autism this anxiety is a result of their problems with sensory processing.4

Scientists have found that children with autism have low levels of brain Serotonin.1 Serotonin is a brain chemical (neurotransmitter) that is involved in the processing of sensory messages, so low Serotonin generally leads to sensory processing problems. When a person’s brain does not translate sensory information well, it results in anxiety.

It is not really surprising that individuals with autism live with a tremendous amount of anxiety when you consider that they may be experiencing an overload of sensory inputs at the same time as not having the communication skills to explain what they need or want. Stimming can help to relieve this anxiety.

For example, an autistic child may constantly jump up and down when he is watching a fun TV show. Even though the child likes the show, the images and sounds may still be causing sensory overload. Stimming is the child’s way to manage the sensory overload and
enjoy the show.

Sensory Enrichment Therapy™ helps with sensory processing

Sensory Processing and anxiety are two of the biggest areas of progress for people with developmental disabilities, including autism, who are doing Mendability’s Sensory Enrichment Therapy. In clinical trials, children doing Sensory Enrichment Therapy as well as their standard therapies saw their Short Sensory Profile score improve by an average of 12 points compared to 3 points for children who did standard care only.5

Mendability helps families to do Sensory Enrichment Therapy, a new brain autism therapy, wherever they live through an online portal and telehealth services. To learn more about Mendability therapy go to www.mendability.com/sensory-enrichment-therapy.

About Sensory Enrichment Therapy

Clinical Studies Validate Sensory Enrichment Therapy as an Effective Autism Treatment

Results showed that after 6 months of therapy 42% of the children in the sensory enrichment group achieved clinically significant improvement, compared to only 7% of the children in the standard care group.
