Paula Dadson, Occupational Therapist  First: What is Sensory Processing?Sensory processing is when the body takes in sensory input, such as a bright light or a noisy classroom, and has the ability to process and interpret that information and react in an appropriate way. Sensory processing difficulties occur when this information does not get organised into an appropriate response leaving the person to feel the sensory input more or less than others would. A person may be seeking or avoiding environmental stimuli, or they may be constantly distracted by some input. Where some may not register the amount of stimuli around them. This can make it very hard for people to complete daily activities when they are constantly under or over stimulated by their environment. It often leads to trouble engaging in a task and being able to concentrate. An example of this is when a child has sensory seeking preferences and is given a task that requires concentration while they sit still at a desk. This child will find it very difficult to focus and complete this task while they are not receiving this sensory input for a long period of time.  Why Deep Pressure?One technique that is proved to increase attention and help organise a response to sensory stimuli is deep pressure. It is hard to understand how deep pressure would help people who are seeking sensory input as well as those who are avoiding this input. Deep pressure provides proprioceptive input which calms and regulates the Central Nervous System. The Central Nervous System includes both a parasympathetic and sympathetic systems which work together to regulate our body. Deep pressure decreases the sympathetic activity that causes your “fight or flight” reaction to stressful situations. It also increases parasympathetic activity which will slow down high energy functions like heart rate, and blood pressure. This will help regulate the body to interpret sensory input and increase attention and concentration. Deep pressure also helps release serotonin and dopamine hormones which increase mood, and stimulates melatonin release to help with sleep. Therefore Deep pressure should help people with sensory processing difficulties to complete those activities they were having trouble with. Some Examples of Deep Pressure
 When might these occur?Children with Autism are most commonly thought of when there is mention of sensory sensitivities or sensory behaviours. One of the criteria that a child with Autism may meet is experiencing hyper (high) or hypo (low) reactivity to sensory input or unusual interests in sensory aspects of the environment. There are also children who may not have a diagnosis who may present with sensitivities to some extent. How do I know what to look for?There are many categories of senses: sight, sound, touch, taste, smell, balance and we can even extend to include proprioceptive and vestibular input. There are two common presentations of sensory sensitivities. Hypersensitivity occurs when sensory input exceeds a person’s ability to cope. This is a low sensory threshold and the child is explained as a sensory avoider. Hyposensitivity occurs when greater than normal levels of input are required for registration. This is a high sensory threshold and the child may be seen as a sensory seeker. Why might a child engage in sensory seeking or sensory avoiding?Whether a child is seeking or avoiding sensory input, there are reasons behind the behaviours we can see. These may include the following, but can include many more:
What can I do to help?As with any behaviour, if we can find out or make a prediction of why it is happening and what function it serves, we have a much better chance of making a successful support plan for the child. But how do you figure this out? Watch your child in various environments and observe their behaviours and reactions or even just ask them. Ask others involved in your child’s care also – it’s important to gather information. Be a detective! Here are some tips that were shared on our blog recently about functions of behaviour – check it out: https://www.hopscotchandharmony.com.au/blog/behaviour-the-importance-of-figuring-out-why. Below are some common examples of behaviours and how you may be able to assist. If a child is seeking sensory enjoyment: Yes, sometimes these behaviours are enjoyable for a child, but are disruptive to the child’s opportunities to socialize or it may be impacting/disrupting their learning or attention. If this is a behaviour that is safe, gently speak to your child (or use pictures) to explain it is not time for this just now; however, they may have some time to engage later. Remember, it’s okay for a child to engage in these behaviours sometimes; they serve a function. You also may like to suggest to a child they engage in these when it is time for them to follow their own ideas/explore their environment or when they take a break. If a child is engaging in a disruptive sensory seeking behaviour: If you believe the behaviour is inappropriate or disruptive, For example, if a child enjoys biting and sucking their school T-shirt, but this is the tenth one you’ve purchased this year! you may like to further explore why are they biting that material in the first place (Boredom? Anxiety? Is it a concentration aid? Does it calm them?). You may then consider providing alternative opportunities that serve the same function. If this really is just for comfort or concentration, they may like to have a more appropriate option (a small piece of similar material available to them that they can use). If this is due to anxiety, we need to look further into teaching effective and appropriate coping skills. Your child needs a proactive strategy. If a child is a sensory avoider, provide appropriate ways for sensory avoiding where possible: Can you help the child to communicate their discomfort in an appropriate way? Or maybe a child can be taught how to minimize the effect the sensory experience has on them. They should always be taught how to cope through a sensory experience as well as being given a way to minimize its effects. The world is an unpredictable place and your child may inevitably experience what they are trying to avoid at some stage. A summary - How do we understand and how do we help?
