Sensory integration therapy (Ayres; contested)

1. Introduction

Version followed: Ayres Sensory Integration® (ASI) as defined by the Ayres Sensory Integration Fidelity Measure (Parham and colleagues; first published 2007, revised 2011) and applied through the Data-Driven Decision Making (DDDM) process of Schaaf and Mailloux's Clinician's Guide for Implementing Ayres Sensory Integration (AOTA Press, 2015), as illustrated in Faller et al. (2016). Where this guide refers to "sensory-based interventions" (weighted vests, brushing protocols, sensory diets, swings used passively), it means a separate group of practices that the sources treat as distinct from ASI. [source: CLASI Fidelity Measure summary; Faller et al. 2016; Nowell et al., NCAEP companion]

What it is. ASI is a theory and practice originated by the occupational therapist A. Jean Ayres. It targets how a person processes and integrates tactile, vestibular (movement and gravity) and proprioceptive (muscle and joint) information. The child takes part in purposeful, playful activity on specialised suspended and floor equipment, at an individually tailored "just right" challenge. Trained therapists, usually occupational therapists, deliver it one to one in specially designed clinic spaces. [source: Nowell et al., NCAEP companion] It is meant to improve how the brain processes and adapts to sensory input, not to teach specific skills. [source: Blue Cross NC policy, describing SIT]

Core idea of how change happens (as proponents state it). The child produces active, self-organised "adaptive responses" to well-matched sensory-motor challenges. Proponents hold that this improves sensory modulation, postural and motor control and praxis (planning new actions), and that these gains then support participation in play, self-care, school and family life. [source: CLASI Fidelity Measure summary; Faller et al. 2016] This is a hypothesised mechanism and is contested (see below). [uncertain]

Who delivers it and regulatory position.

• Profession. Occupational therapists deliver ASI, sometimes speech-language pathologists or physiotherapists with ASI training. Educators and caregivers are not qualified or expected to deliver ASI on their own; they may carry out some SI-related activities under an OT's direction. [source: Nowell et al., NCAEP companion]
• Regulators. In the UK, occupational therapists are registered with the Health and Care Professions Council (HCPC); Sensory Integration Education's postgraduate SI awards require HCPC or equivalent registration and admit OTs, physiotherapists, speech and language therapists, practitioner psychologists, arts therapists, nurses and social workers. The same provider states that SI training sits inside each person's core profession and that SI is "not a stand-alone therapy". [source: Sensory Integration Education entry criteria] In the US, OTs practise under state licensure, with NBCOT certification and AOTA as the professional body. [uncertain: not verified] Post-professional ASI certificates are offered by CLASI and partner trainers (e.g. ASI Wise). [source: ASI Wise / CLASI certificate page, title only; uncertain: course content not verified]
• It is not a regulated medical device or medicine; there is no labelling. Coverage policy is a practical indicator of status: Blue Cross NC (reviewed June 2025) classes sensory integration therapy as investigational and does not cover it. [source: Blue Cross NC policy]

Evidence status (attributed; contested).

• AAP 2012 (Zimmer, Desch et al., Pediatrics 129(6):1186–1189): research on effectiveness is "limited and inconclusive"; paediatricians should not use "sensory processing disorder" as a diagnosis, should assess for autism, ADHD, developmental coordination disorder and anxiety, should tell parents about the limited evidence, and, if a family chooses therapy, help them set "specific goals, timeframes, and measures of success"; families should know that "occupational therapy is a limited resource". [source: Contemporary Pediatrics 2012 report; Blue Cross NC policy]
• AAP 2020 autism clinical report (Hyman et al.): evidence for sensory-based therapies "remains currently limited". [source: Blue Cross NC policy]
• AOTA 2011 practice guideline (Watling et al.) gave sensory integration a Level C recommendation for some goals; AOTA's 2015 school-practice statement found insufficient evidence for academic outcomes. [source: Blue Cross NC policy]
• NCAEP 2020 (Steinbrenner et al.) listed ASI as a new evidence-based practice for autistic children on the basis of three randomised group studies, while finding insufficient evidence for passive sensory-based practices. [source: Nowell et al., NCAEP companion]
• SenITA trial (Randell et al. 2022, Health Technology Assessment 26(29); 138 autistic children in mainstream primary school, Wales and England): manualised SIT over 26 weeks with good fidelity "did not demonstrate clinical benefit above standard care" on problem behaviour and was not cost-effective; carer-rated individual goals improved, but whether this adds to usual care is unclear. [source: DOAJ record of Randell et al. 2022]
• Kishida, Stephenson, Kemp & Salisbury (2026) systematic review of studies adhering to the revised ASI fidelity measure (10 studies, 171 children): research quality generally poor, fidelity often unreported; no strong evidence of effectiveness. [source: InSpEd research summary, June 2026]
• Neurodiversity-affirming critiques argue that therapy for autistic people often tries to "normalize" ways of being, and call for goals built with neurodivergent clients (Dallman, Williams & Villa 2022); an RCOT-hosted summary of a scoping review urges strengths-based, environment-first support and reducing pressure to mask. ASI trainers reply that ASI is person-led and aims at participation, not normalisation (Smith, ASI Wise, 2025). [source: Dallman et al. 2022 abstract; RCOT 2025; ASI Wise blog 2025]

ASI versus "sensory-based interventions". Sources draw this line sharply: brushing protocols, swings, weighted vests, squeeze machines, weighted blankets, sensory diets, sensory gyms, touch therapy and auditory integration therapy are not ASI, and using the terms interchangeably is described as inaccurate. [source: Nowell et al., NCAEP companion] When a family says a child "has sensory integration", find out which of these they mean. [synthesis]

2. Framework

ASI is an OT intervention delivered within a cycle of assessment, hypothesis, goals, intervention and measurement. The DDDM process gives eight steps; the psychotherapist's parallel tasks are listed with each. [source: Faller et al. 2016; psychotherapist tasks: synthesis]

[source: Faller et al. 2016 for OT steps and tools]

Format and course length. Studies typically delivered ASI one to one in clinic, about an hour two or three times a week [source: InSpEd summary of Kishida et al. 2026]; the Faller case ran for 10 weeks [source: Faller et al. 2016]; SenITA ran 26 weeks [source: Randell et al. 2022]. There is no standard course length; the AAP advice is to set goals, timeframes and success measures in advance. [source: Contemporary Pediatrics report of AAP 2012]

Who it is for. ASI is for children with clinically significant sensory processing difficulties, not for all autistic children, and should be decided by an interdisciplinary team including an OT. [source: Nowell et al., NCAEP companion] Reviewers were concerned that nearly half of studies enrolled children on diagnosis alone. [source: InSpEd summary]

Moving between phases. Within sessions the OT moves from sensory-motor play aimed at perception and over-reactivity towards praxis challenges, adjusting intensity, duration and equipment to the child's responses. [source: Faller et al. 2016] Across the course, the decision point is step 8: if outcomes do not change, the hypothesis is revised [source: Faller et al. 2016]; or, in line with AAP advice, the family reconsiders continuing. [synthesis]

Fidelity structure. The fidelity measure has structural parts (therapist qualifications, safe environment, record review, space and equipment, communication with parents and teachers) and a process part rating ten therapist strategies on video or observation, each on a four-point scale from "no" to "certainly" intentional. [source: CLASI Fidelity Measure summary and self-study scoring documents] The measure is copyrighted and not reproduced here.

3. Guiding principles

The ten process elements of the fidelity measure are the clearest statement of ASI principles; paraphrased here with their practical meaning for a psychotherapist observing or coordinating. [source: CLASI Fidelity Measure summary]

• Ensures physical safety. The OT protects the child while allowing challenge; ask how falls and equipment risk are managed.
• Offers sensory opportunities. At least two of tactile, vestibular and proprioceptive input are offered; this is active play, not passive application.
• Supports sensory regulation. The therapist helps the child reach and stay in a workable state of arousal, mood and activity; a dysregulated child is a cue to change course, not push on.
• Challenges postural, ocular, oral or bilateral motor control. Activities build body control; the child is moving, not being moved.
• Challenges praxis and organisation of behaviour. The child plans new actions and sequences; expect problem-solving, not drills.
• Collaborates on activity choice. The child has a real say in what happens; a session run entirely by the adult is a fidelity failure.
• Tailors the just-right challenge. Difficulty rises as the child succeeds; frustration or boredom means mis-matched challenge.
• Ensures success. Tasks are set so the child can achieve an adaptive response.
• Supports intrinsic motivation to play. Engagement comes from play, not rewards or demands.
• Fosters therapeutic alliance. Goals are pursued as a mutually enjoyable partnership; the relationship is itself an ingredient.

Further principles from the sources:

• Use data to guide practice. Measure goals before and after and revise the hypothesis when nothing changes. [source: Faller et al. 2016]
• Precise terms. Say "ASI" only for fidelity-consistent practice; name sensory-based interventions as such. [source: Nowell et al., NCAEP companion]
• Not a stand-alone therapy. It follows a full assessment of needs and sits inside a professional's core practice. [source: Sensory Integration Education]
• Honest information for families. Parents should be told the evidence is limited and that OT time is a limited resource. [source: Contemporary Pediatrics report of AAP 2012]
• Participation over normalisation. Goals should support meaningful participation and affirm neurodivergent ways of being rather than suppress them. [source: Dallman et al. 2022 abstract; ASI Wise 2025]
• The child's assent is ongoing. Child choice in ASI and child-led play give a natural place to honour "no"; touch and movement input need explicit, revocable agreement. [synthesis]
• Safeguarding comes first. One-to-one physical work with children requires the service's safeguarding policies, visible practice and parent access. [synthesis]

4. Intervention inventory

Part A describes, at a descriptive level only, what the occupational therapist does, so you can explain it and recognise departures from it. Part B gives the psychotherapist's own interventions. You do not deliver ASI unless you hold the relevant registration and post-professional ASI training and your core-profession scope covers it. [source: Nowell et al., NCAEP companion; Sensory Integration Education]

A1. OT assessment and hypothesis (delivered by the OT)

• Purpose: Decide whether a child has clinically significant sensory integration or praxis difficulties that plausibly limit participation. [source: Faller et al. 2016; Nowell et al.]
• Steps (as described): Parent interview and history; standardised testing such as the SIPT (17 tests of sensory discrimination, integration and praxis); caregiver questionnaire (Sensory Profile); a participation measure (PEDI); structured clinical observation. Findings are tied to named participation problems in a written hypothesis. [source: Faller et al. 2016] Other ASI assessments exist (e.g. the newer Evaluation in Ayres Sensory Integration). [uncertain: not verified]
• Example language (to a parent, illustrative): "The OT's assessment asks a specific question: are there body and sensory processing differences that explain the dressing and playground problems you described? It may also say no."
• Watch for: Therapy recommended on diagnosis alone without a sensory-motor hypothesis [source: InSpEd summary]; "sensory processing disorder" given as the only explanation without screening for anxiety, ADHD, developmental coordination disorder or autism, which the AAP advises against. [source: Contemporary Pediatrics report of AAP 2012]

A2. Goal setting and outcome measurement (OT, with family)

• Purpose: Fix concrete, family-owned participation goals and how they will be judged.
• Steps (as described): Occupation-based goals (e.g. waking quietly and playing, dressing, play with siblings, playground safety, sitting through a religious service) scaled with Goal Attainment Scaling, verified with the parent; proximal (sensory-motor) and distal (participation) measures chosen in advance; outcomes graphed and reviewed. [source: Faller et al. 2016]
• Example language (illustrative): "Before therapy starts, can we write down two or three things you'd see at home if it was helping, and agree when we'll look again?"
• Watch for: Goals that are only about stopping behaviour the adults find inconvenient; no review date; outcomes only reported by people with a stake in continuing. Parent-reported outcomes were a noted source of bias in the research. [source: InSpEd summary; synthesis]

A3. The ASI session (OT)

• Purpose: Elicit active adaptive responses through play at a just-right challenge.
• What it looks like (descriptive): A large clinic room with suspended equipment (swings, trapeze), foam wedges, ball pits, mats, and tactile media; activities such as pushing, pulling, hanging, climbing, antigravity positions and tactile play; often pressure input from blankets or stretchy fabric and oral-motor play. The child co-chooses activities; the OT adapts intensity, duration and equipment moment to moment. [source: Faller et al. 2016; Blue Cross NC; CLASI Fidelity Measure summary] Specific activity protocols are not given here.
• Example language (to a child, illustrative): "In OT you get to choose a lot of the games, and you can always say stop."
• Watch for: A session that is adult-directed drill, passive application of input, or continues through the child's distress; these depart from the fidelity elements (shared choice, regulation, success, alliance). [source: CLASI Fidelity Measure summary; synthesis]

A4. Fidelity monitoring (OT, service)

• Purpose: Check that what is called ASI matches Ayres' principles.
• What it is: Structural review (qualifications, safe environment, records, space and equipment, parent and teacher communication) and observed rating of the ten process strategies. [source: CLASI documents] Fidelity was often unreported in the research. [source: InSpEd summary]
• Example language (to the OT, illustrative): "Is your service using the ASI fidelity measure, and would the family's sessions meet it?"
• Watch for: "ASI" offered in a classroom or as a home programme alone; the NCAEP companion says ASI is not currently appropriate for classroom delivery. [source: Nowell et al.]

A5. Sensory-based interventions (often confused with ASI)

• Purpose (as claimed by users): Calm or alert a child through applied input: brushing protocols, weighted vests or blankets, squeeze machines, swings, sensory diets, sensory rooms. [source: Nowell et al.]
• Status: Insufficient evidence for these practices in the NCAEP 2020 review; they are not ASI. [source: Nowell et al.] Antecedent-based changes to the environment (e.g. reducing aversive noise) are an evidence-based alternative for aversive sensory experiences. [source: Nowell et al.]
• Example language (illustrative): "A weighted vest at school is a different thing from the Ayres therapy you read about; they have different evidence and different risks. Shall we ask the OT who set it up what it's for and how it's reviewed?"
• Watch for: Any weighted or pressure item a child cannot remove themselves, that restricts movement or breathing, or that is used to keep a child seated or as a consequence; treat this as restrictive practice and raise it under safeguarding. [synthesis] Brushing or touch applied over a child's objection. [synthesis]

A6. Parent and teacher communication (OT)

• Purpose: Translate assessment and goals into everyday understanding; structural fidelity includes communication with parents and teachers. [source: CLASI self-study scoring document]
• Description: Caregivers and educators may carry out SI-related activities under the OT's direction and training, but do not deliver ASI themselves. [source: Nowell et al.] In the Faller case, parent involvement was limited to interviews, questionnaires and goal ratings. [source: Faller et al. 2016]
• Example language (illustrative): "What has the OT asked you to do at home, and how is it going for you and your child?"
• Watch for: Parents given long home "sensory" routines that add load to the family or become a battle with the child. [synthesis]

B1. Recognising when to suggest OT or paediatric review

• Purpose: Route sensory, motor and praxis concerns to the right assessor and keep psychological explanations on the table. [synthesis, consistent with AAP 2012 advice to assess for other conditions]
• Steps: (1) Note sensory reports: distress at noise, textures, clothing, grooming; seeking movement or pressure; clumsiness; difficulty planning new actions. (2) Ask about impact on sleep, dressing, eating, play, school and family routines. (3) Consider anxiety, trauma, ADHD, developmental coordination disorder and autism as alternative or co-occurring explanations. (4) With consent, suggest the family discuss an OT assessment via the GP, paediatrician or school route. (5) Share your formulation in writing with the referrer. [synthesis]
• Example language (illustrative): "Some of what you describe sounds like how your child's body handles touch and movement. An occupational therapist can assess that properly. I'd also keep looking at worry, because both can be going on."
• Watch for: Your own drift into giving sensory advice beyond your training; families seeking a sensory label to avoid an autism or ADHD assessment, or the reverse. [synthesis]

B2. Psychoeducation: what ASI is and is not

• Purpose: Help families understand the difference between ASI and sensory-based interventions and the state of evidence, without advising for or against. [source: Nowell et al.; Contemporary Pediatrics report of AAP 2012]
• Steps: (1) Ask what they have heard and what they hope for. (2) Explain ASI as OT-delivered, play-based, clinic work at a just-right challenge. (3) Explain that weighted vests, brushing and sensory diets are different practices. (4) Give the evidence fairly and attribute it: AAP 2012 and 2020 call the evidence limited; NCAEP 2020 counted ASI as evidence-based for some autistic children; the UK SenITA trial found no benefit over usual care on its main outcome. (5) Offer written sources. [source: Contemporary Pediatrics report of AAP 2012; Blue Cross NC; Nowell et al.; Randell et al. 2022]
• Example language (illustrative): "Professional bodies disagree here. The paediatricians' academy calls the evidence limited; an autism research centre counted ASI as evidence-based for some children; a large UK trial found no benefit on behaviour over usual care. What matters is whether it helps your child's goals, and that's something you can check."
• Watch for: Parents feeling blamed for having tried or declined therapy; overselling or dismissing; claims that therapy will "rewire the brain" or treat autism itself. [synthesis]

B3. Supporting informed consent and shared decision-making (parents)

• Purpose: Help parents make a values-based decision about starting or continuing OT, using the AAP's goals-timeframe-measures frame. [source: Contemporary Pediatrics report of AAP 2012]
• Steps: (1) Clarify the family's priorities and the child's view. (2) List what therapy would cost in time, travel, money and the child's energy (OT is "a limited resource"). (3) Write down two or three measurable goals and a review date with the OT. (4) Name alternatives the team may offer (e.g. environmental adaptation, other evidence-based supports). (5) Respect the decision; the treating OT, not you, gives the clinical recommendation. [source: AAP 2012 via Contemporary Pediatrics; Nowell et al.; synthesis]
• Example language (illustrative): "You don't need to decide today. If you go ahead, what would you want to see by the review, and how will you know?"
• Watch for: Decisions driven by fear or by fear of missing out; pressure from providers or forums; a child's clear objection being overridden. [synthesis]

B4. Child assent and touch consent

• Purpose: Keep the child's voice central in a hands-on, movement-based therapy. [synthesis; fits the fidelity elements of shared choice, regulation and alliance, CLASI]
• Steps: (1) Explain therapy to the child in developmentally suitable words, pictures or visual supports. (2) Agree how the child signals stop, including non-speaking signals. (3) Ask the family and OT how touch, holding, spotting, pressure input and being lifted onto equipment are explained and agreed with the child. (4) Check the child can see and reach a parent or exit. (5) Revisit assent regularly; repeated refusal is information for the review, not a behaviour to overcome. (6) For older children and adolescents, legal rules on capacity to consent vary by jurisdiction; follow your service and regulator. [synthesis; uncertain: jurisdiction-specific age limits not verified]
• Example language (to a child, illustrative): "Your body belongs to you. In OT, grown-ups should ask before they touch you, and if you show your stop sign, they stop. Has that been happening?"
• Watch for: Fear, freezing, compliance without enjoyment, distress before OT days, disclosures about touch; children with trauma histories for whom pressure, restraint-like holds or being lifted may be triggering. [synthesis]

B5. Safeguarding in sensory-based and one-to-one physical work

• Purpose: Prevent and respond to harm in work that involves touch, equipment and pressure. [synthesis]
• Steps: (1) Know your local safeguarding procedure and lead. (2) Ask whether sessions are observable or parents can attend. (3) Treat as safeguarding concerns: items or holds a child cannot escape, weighted products used to restrain or seat a child, input continued over distress, isolation as "sensory" time-out, secrecy. (4) Record what the child or parent said in their words, consult the lead and follow the referral route; do not investigate yourself. (5) Distinguish poor practice (raise with the OT or service) from abuse (refer). [synthesis]
• Example language (to a parent, illustrative): "You mentioned the vest is kept on even when he's crying. I need to share that with the school's safeguarding lead so it gets looked at properly."
• Watch for: Unexplained injuries; the child avoiding specific adults; the family being told not to watch. [synthesis]

B6. Collaboration and information sharing with the OT

• Purpose: One formulation, shared goals, no contradictory advice. Sensory needs should be addressed by an interdisciplinary team including an OT. [source: Nowell et al.]
• Steps: (1) Obtain consent to share. (2) Exchange formulations: the OT's sensory-motor hypothesis and your psychological one. (3) Agree a shared vocabulary for regulation that the child also uses. (4) Agree review points aligned with the OT's goal measures. (5) Name who leads on what. [synthesis; DDDM review step from Faller et al. 2016]
• Example language (to the OT, illustrative): "I'm working with anxiety around separation and school. Could we line up our goals so we're not asking the family for two different routines?"
• Watch for: The child getting different messages about their body or feelings from different professionals; scope creep in either direction. [synthesis]

B7. Integrating psychological work alongside OT

• Purpose: Address what OT does not: anxiety, trauma, low mood, family stress, identity and self-understanding. [synthesis]
• Steps: (1) Help the child build their own words or pictures for body states (co-created language is also recommended by ASI trainers). (2) Work on anxiety and avoidance with your usual evidence-based methods, adapted for sensory differences. (3) Support parents' understanding, stress and guilt. (4) Use environmental adaptation as a first line where sensory input is aversive (e.g. noise reduction), with the school and OT. (5) For autistic young people, support identity and self-advocacy and reduce pressure to mask. [source: ASI Wise 2025 for co-created language; Nowell et al. for antecedent-based adaptation; RCOT 2025 for masking; rest synthesis]
• Example language (to a young person, illustrative): "Lots of people's bodies react strongly to noise. That isn't something wrong with you. Let's work out what helps, and what you'd like teachers to know."
• Watch for: Therapy framed as making the child appear less autistic; exhaustion after masking; mood dips if therapy is experienced as a judgement. [source: RCOT 2025; Dallman et al. 2022; synthesis]

B8. Monitoring and passing on concerns

• Purpose: Notice and relay adverse or unexpected responses to the OT and family. [synthesis]
• Steps: Track sleep, distress, avoidance, aggression, falls or injuries, and the child's stated views; pass concerns to the OT with consent; escalate safeguarding concerns as in B5. [synthesis]
• Example language (illustrative): "Since OT started, has anything got harder as well as easier?"
• Watch for: Overstimulation signs reported after sessions (agitation, shutdown); new fears of equipment or of being touched. [synthesis]

B9. Reviewing continuation and endings

• Purpose: Help the family use pre-agreed goals to decide whether to continue, change or stop. [source: AAP 2012 via Contemporary Pediatrics; Faller et al. 2016 on revising the hypothesis]
• Steps: Review goal ratings with the OT's data; ask the child; consider cost and burden; prepare the child for ending OT; carry forward useful strategies into home and school. [synthesis]
• Example language (illustrative): "We agreed to look again at twelve weeks. Which goals moved, which didn't, and what does your child say?"
• Watch for: Indefinite courses without review; endings experienced as failure. [synthesis]

5. Handling problems

The sources address few of these directly; guidance is [synthesis] unless a source is given.

• Family convinced ASI is essential, or desperate for any intervention. Validate the wish to help; return to goals, timeframes and measures; set a review date with the OT. [source: AAP 2012 via Contemporary Pediatrics; synthesis]
• Family hostile to OT after reading critiques, or a teen rejecting it as "trying to fix me". Take the critique seriously; ask what participation goals the young person themselves has; explore environmental adaptation first; the decision is theirs and the team's. [source: Dallman et al. 2022; RCOT 2025; synthesis]
• Child refuses or is distressed in sessions. Treat refusal as communication: share with the OT and parents; check challenge level, regulation and touch practices; never support overriding assent. Fidelity elements expect shared choice and success, so persistent distress means the session is not working as designed. [source: CLASI Fidelity Measure summary; synthesis]
• No change after the agreed period. Support the family to raise it at review; the DDDM process expects the hypothesis to be revised when outcomes do not change. [source: Faller et al. 2016]
• Non-adherence to home programmes. Explore burden and conflict; ask the OT whether the programme can be simplified; protect the parent–child relationship over routine completion. [synthesis]
• "Sensory" used to explain all distress. Keep anxiety, trauma, pain, sleep, communication and unmet needs in the formulation; suggest medical review for pain, sleep or new behaviour changes. [synthesis, consistent with AAP 2012 advice to evaluate other conditions]
• Sensory-based practices presented as ASI (e.g. a weighted vest plan called "sensory integration therapy"). Name the difference, ask the provider for the rationale and review plan, and raise restrictive or distressing use under safeguarding. [source: Nowell et al.; synthesis]
• Rupture with the family (e.g. after you share a safeguarding concern or voice doubt about the evidence). Acknowledge their intention to help their child; explain your duty plainly; repair by restating shared goals. [synthesis]
• Conflicting advice between professionals. Request a joint review; agree one plan and shared language; avoid commenting on another professional's clinical competence in front of the family. [synthesis]
• Trauma histories. Pressure, holding, being lifted or restricted, and loss of control can be triggering; ask the OT how these are adapted and agree warning signs together. [synthesis]
• Costs and access. Coverage is often refused (e.g. classed as investigational by Blue Cross NC); OT time is limited; help families weigh opportunity costs. [source: Blue Cross NC; AAP 2012 via Contemporary Pediatrics]
• Your own scope. If you are tempted to add sensory activities to your sessions, check training, registration and service policy; ASI requires post-professional training and specialised equipment and space. [source: Nowell et al.; Sensory Integration Education; CLASI documents]
