You often don’t give a second thought to biting into an ice cream sandwich, riding a bicycle, or watching a movie. For children who have difficulty with sensory processing these activities, become insurmountable hurdles that result in what most people see as inexplicable and out of control response from their child, including tantrums, anxiety, excessive clumsiness, carelessness, and academic failure.
The child could very likely be having difficulty integrating information that comes in from their senses, primarily sound, touch, and sight. Commonly known as Sensory Processing Disorder (SPD), the condition affects approximately 1 in 6 children in ways that are significant enough to detrimentally affect daily activities and healthy functioning. For these children, the brain and nervous system encounter a glitch in receiving messages from the senses, interpreting them, and converting them into appropriate motor and behavioral responses. Children can be affected in one sense or across multiple senses. One child may over-respond while another may under-respond to the same sensory stimuli.
There are many theories about the causes of SPD, but no single factor is responsible. While more research is needed, studies to date indicate that a complex interaction of genetics and environment determine how symptoms of SPD develop for any particular child.
An innovative system for addressing SPD is the Integrative Listening System (iLs), a multi-sensory system that integrates music, movement, and language exercises to help improve brain function. The premise behind iLs is that stimulation of movement, balance, vision, and auditory pathways are vital to the ability to pay attention, process information, coordinate movement, learn and respond. The key components of iLs are air and bone conduction, conveyed through headphones, along with visual and motor input.
Bone conduction and air conduction are the two ways we hear sound. If you’ve ever heard your voice on an audio recording and said, “that doesn’t sound like me” it’s because you’re only hearing the air conduction of your voice. When you speak, your voice is projected over both air and bone conduction, which happens over the mastoid bone just behind your ear. That’s also why, when you have your hearing checked, a vibrator is place on that mastoid bone—it is a test of bone conduction responsiveness and it is crucial in the processing of sensory stimuli.
Integrative Listening Systems uses different frequencies and different levels of sound filtration to selectively train parts of a child’s auditory spectrum. This helps improve learning-related abilities such as sound decoding and auditory memory. The muscles of the inner ear are also trained through a process that triggers patterns of relaxation and response. As the muscle patterns become stronger, the child’s ability for focused listening and attention to tasks can improve.
As lower-level processing tasks strengthen, higher-level processing activities are introduced. These higher-level tasks, such as expressive language training and complex cognitive activities influence the neurological pathways that relay and process sensory information, helping to release the “glitch” that had kept the child entangled in a snare of sensorimotor stimuli.
The results of a successful iLs program for a child with sensory processing challenges can include:
Using the iLs program usually begins with intense sessions with a child’s occupational therapist. The program is also easy to use at home and is often recommended to maintain progress.
