Sensory integration issues and ASD Information Booklet and strategies - Sensory integration is a neurological process that occurs in the brain, it’s an unconscious automatic process, to give us meaning, allows us to respond in a purposeful way, and forms the foundation for learning and behaviour. - Our 7 senses are: vision, hearing, touch, smell, taste, and then we have the sense of movement (the vestibular system) and the positional sense (proprioception system). - Sensations flow into the brain like traffic, the brain locates sorts and orders these sensations, when sensations flow in a well organised manner the brain can use these sensations to form perceptions, behaviour and learning. - People with ASD process and respond to sensory stimuli in a much different way and they have a different physiological response to sensory stimuli than typically developing people (tone and tactile - lower). Difficult to work out exactly what the sensory issues are as each is unique and affected by other issues e.g. illness, mood. - 80-90% of individuals with ASD experience atypical sensory responsiveness that affects their ability to take part in daily life. - Sensory processing disorder is like a computer breaking, incorrect information is put in, it’s not been made sense of and the response is inappropriate. This changes how a person will respond to changes in their own body, the environment and how they interact with it and others around them. - Sensory needs are becoming more recognised in ASD. The DSM V states “Hyper-or hypo-reactivity to sensory input or unusual interest in sensory aspects of environment; (such as apparent indifference to pain/heat/cold, adverse response to specific sounds or textures, excessive smelling or touching of objects, fascination with lights or spinning objects)” as part of the diagnostic criteria. - Brain gut connection – After a painful event a much smaller event may trigger a painful reaction. E.g. if a child eats lots of cold food when young and gets severe pain, a small amount later on can cause major pain as a pain message has been stored – the same can be said for smells, lights etc . (Dr Wendy Lawson – Sensory Issues in Autism). - Some autistic individuals can see the flicker of florescent lights. (Lawson, 2001) Coleman et al (1976) found that florescent lights increased repetitive behavior in some children with autism. (Dr Wendy Lawson – Sensory Issues in Autism). - What we know about ASD is that we use single attention. If attention is all in one place then sensory issues will take precedence when they exist. I won’t have spare attention for learning, my senses are occupied! (Dr Wendy Lawson – Sensory Issues in Autism). - Please note it can be difficult to work out exactly what a person’s sensory issues are because each person will experience things differently and respond in different ways. Everyone’s tolerance levels are affected by their well being so if tired, ill, stressed etc we might not be as tolerant of sensory stimuli as when we are feeling good. Type of sensory need What’s happening Hypersensitive Meaning brain channel is too open and as a result too much information passes into the brain to handle. Signs/Symptoms Dislike to dark / bright lights Notices minute detail Covers ears Resists touch Runs from smells Moves from people Uses Tip of tongue for tasting Craves certain food Places body in strange positions. Turns whole body to look Difficulty walking on uneven surfaces. Hyposensitive Meaning brain channel not fully Moves fingers or objects in front of eyes open and brain is deprived of Fascination with bright/coloured objects / information. reflections Makes loud noises (can be rhythmic) Likes vibration, pressure, tight clothes Enjoys rough and tumble play Smells things (including self and people) and seeks strong smells Puts objects in mouth, licks things Eats anything Rocking and Spins/runs round and round Lack of body awareness / Bumps into things Sensory Overload Meaning too much information all at once. Trying to process everything at once. Needs to be in control of environment. Sudden outbursts of self injury or distress Tires easily in stimulating places (noises). Nausea/vomiting from lots of movement Withdrawal Might see certain behaviours to calm down or stop pain This might work because… - Rocking, - swinging, - flapping - spinning, - hit or press against myself These cause sensations to help my brain block things out. - Banging, - Seeking of noises - Tight clothes - Self injures - Smearing These causes sensations which help my brain get more information in from outside (get the nervous system working more). Use one sense at a time, avoid direct involvement with stimulus, remove self or withdraws, engages in rituals and routines. This may reduce the feeling of being overloaded and cut out some sources, allowing recovery. Type of sensory need What’s happening Signs/Symptoms Might see certain behaviours to calm down or stop pain Gestalt Perception Meaning difficulties filtering background and foreground information so everything is seen as a whole (this can happen in any sense). This may mean that if a picture is hanging at an angle this will change the whole scene and environment will become unfamiliar. Can impact if routine is changed. - Fear Notices every tiny change in environment Easily frustrated if trying to work in noisy - Stress - Frustration crowded room Clumsy – stiff movement Does not follow instructions with more than one person talking Fragmented Perception Difficulty seeing things as a whole/processing all relevant parts of something at once e.g. a person might appear as lots of unconnected parts – each being unpredictable due to movement of them – processing them bit by bit - but can see a whole person. - Delayed Processing Meaning a delay in the time taken to process information that is coming in. - This might work because… Can complicate interpretation of facial expressions and body language. Very narrow focusing of attention Resists change Gets lost easily Difficulty recognising people in unfamiliar clothes Hears few words of a sentence Complains about some parts of clothes, smells etc Attention for minor parts of scene Complain about body parts Focus on one thing e.g. own breathing, arranging furniture, tearing paper, rubbing fingers / hands, Delayed responses Poor at sport Oblivious to risks Experiences perceived as new despite number of times they have already experienced it. Confusion, having to break Need time to process the down the process each time language / object etc to to understand what it is and make sense of it. what it can be used for (e.g. for known objects etc). Physical activities running, bouncing. Concentrating on one thing cuts down amount of processing my brain has to do, e.g. Increase endorphins in brain which help calm down the over stimulation. Get away from the issue Avoiding can help e.g. block ears, shut eyes, recover and prevent leave room. escalation. Unable to transfer skill to a different area / situation. Type of sensory need Distorted perception What’s happening Meaning brain may misinterpret or change what it can really see, hear, touch, smell or taste. This gets worse in state of sensory overload. Signs/Symptoms - Sensory shutdown Compensation Might see certain behaviours to calm down or stop pain Fears heights and stairs Difficulty catching balls Spaces expand or decrease Cant associates the location form and texture of objects Double vision Seeing things in 2D only Poor awareness of own body. - Startled approached - Compulsive repetitive body movements - Hits eyes, ears, nose. Shut down one or more This may reduce sensory channel incoming information to Withdraws cope better. Avoids Engage in routine/rituals Happen when they can’t deal with all the information coming in e.g. if overload occurs. Can occur if one or more senses cannot cope. - May not react to any stimuli Appears to not know how to move own body Disorientated in noisy/bright places Rocks unconsciously whilst doing other activities. - Due to the above sensory sensitivities a person may compensate through other more reliable senses to build a better understanding of the environment. - Investigate objects Look for sound source Inspect food before eating Watches feet while walking, watch hands when doing things Avoids walking on uneven ground. - - This might work because… - - - when Smell, lick, touch or tap Uses other sensory objects, systems to give reliable information so I can Looking at hands and make sense of it. feet when in action, Refusal to walk certain flooring. on Simple Strategies Ways to help: sight Hypo (under-sensitive) Increase the use of visual supports. Hyper (over-sensitive) Reduce fluorescent lighting - use deep-coloured light bulbs instead. Wear sunglasses. Create a workstation in the classroom: a space or desk with high walls or divides on both sides to block out visual distractions. Use blackout curtains. Ways to help: sound Hypo Use visual support to back up verbal information. Hyper Shut doors and windows to reduce external sounds. Prepare a person before going to noisy or crowded places. Wear ear plugs. Listen to music. Create a workstation. Ways to help: touch Hypo Use weighted blankets or sleeping bags. Hyper Warn a person if you are about to touch him or her; always approach him or her from the front. Remember that a hug may be painful rather than comforting. Gradually introduce different textures - have a box of materials available. Allow a person to complete activities themselves (e.g. hair brushing / washing) so that they can do what is comfortable for them. Ways to help: taste Some people with an ASD are hyper- or hyposensitive to taste, and may limit themselves to bland foods or crave very strong-tasting food. As long as someone eats a bit of a varied diet, this isn't necessarily a problem. For more information about ASD and restricted diets, visit www.autism.org.uk/restricteddiet Ways to help: smell Hypo Hyper Use strong-smelling products as rewards and to distract people from inappropriate strong-smelling stimuli (like faeces). Use unscented detergents or shampoos, avoid wearing perfume, and make the environment as fragrance-free as possible. Ways to help: balance Hypo Encourage activities that help to develop the vestibular system. For children this could include using rocking horses, swings, roundabouts and seesaws, try games like catching a ball or practise walking smoothly up steps or curbs. Hyper Break down activities into small, more easily manageable steps; use visual cues such as a finish line. Ways to help: body awareness Hypo Position furniture around the edge of a room to make navigation easier. Put coloured tape on the floor to indicate boundaries. Use the 'arm's-length rule' to judge personal space. This means standing an arm's length away from other people. Hyper Do 'fine motor' activities like lacing boards, pin boards, finger painting, Lego play etc. Ways to help: picky eaters Possible reasons: sensitive to taste or texture, or unable to feel food around the mouth. Possible solutions: change the texture of food, for example purée it. Slowly introduce different textures around the person's mouth, such as a flannel, a toothbrush and some different foods. Encourage activities that involve the mouth, such as whistles or bubble wands. Ways to help: a child that chews on everything, including clothing and objects Possible reasons: may find this relaxing, or enjoy the sensation of chewing on the item. Possible solutions: offer latex-free tubes, straws or hard sweets (chill in the fridge). Ways to help: smearing Possible reasons: may like the texture of faeces or not be very sensitive to smells. Possible solutions: try and introduce things like jelly, or corn flour and water to handle instead; introduce alternative strong-smelling items. Ways to help: children that refuse to wear certain clothes Possible reasons: may dislike the texture or pressure of clothes on their skin. Possible solutions: turn clothes inside out so there is no seam; remove any tags or labels, allows the person to wear clothes they're comfortable in. Ways to help: children who find it difficult getting to sleep Possible reasons: may have difficulty shutting down their senses, in particular sight and hearing. Possible solutions: use blackout curtains or weighted blankets; listen to music to cut out external sounds. School strategies - How we can help – consider tone of voice, what we wear (clothes and jewellery) our movements and actions, perfumes and deodorants, proximity and eye contact, make up etc can affect the child. - De-clutter classroom or the working space – have organised work spaces – adopt the TEACCH classroom layout / visual timetables (clear start and end to task) / timers, work trays etc. - Have clear boundaries for them e.g. privacy boards / pop up partitions, quiet area and hide outs. - Sensory diets – sensory enriched activities - regular access to movement opportunities to provide children’s sensory system with the input they require to achieve a calm alert state – 2-3 minutes of movement can increase concentration for 15-20 minutes (do 3 times a day) e.g. raise hands, clap, wriggle toes, bend wrists, open and close your hands, flex your feet, bend your neck, make a funny face. Schedule movement breaks at least 3 times daily for the whole class i.e. morning, mid morning, mid afternoon. - Heavy work activities (heavy muscle work for proprioception or linear/ rotary movement’s for vestibular) – complete twice a day, 15 minutes of activities can increase attention for up to 2 hours e.g. whole body movements e.g. push ups, hula hoops, star jumps etc. (Linear movements e.g. lying on a gym ball, jumping on a tapeline, and Rotary movements e.g. swing round on a tyre swing) - Seating positions – therapy balls, wobbly cushions, Rocking chairs, busylegz, and ball chairs. - Visual means for the child to show its getting too much e.g. stress thermometer, traffic lights have an agreed exit strategy. - Time out in dark areas, quiet areas, enclosed areas, tents. - Music – for calming and regulating (Mozart), attention (Vivaldi) or arousal and co-ordination (clear rhythm and beat). - Weighted products (lap pads, blankets, jackets) – provide pressure that helps them to relax. - Oral motor strategies e.g. chewing, sucking, crunching, blowing. - Sensory tool kit – individual to each child – e.g. iPods, ear defenders, headphones etc., sunglasses, jumpers with hoods, heavy coat, miracle belt, backpack, finger fidgets (pushing, pulling, squeezing massaging), stress balls, lycra undergarments etc. - Teach child to self-regulate by identifying the signs (alert program – how does your engine run). - Therapy is undertaken by OT e.g. SITS, sensory diets, alert program, and deep pressure techniques.
