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…

Format

• Format and course length. Studies typically delivered ASI one to one in clinic, about an hour two or three times a week; the Faller case ran for 10 weeks; SenITA ran 26 weeks. There is no standard course length; the AAP advice is to set goals, timeframes and success measures in advance.
• 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. Across the course, the decision point is step 8: if outcomes do not change, the…

Who practises it, and how they are trained or regulated

• 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.
• 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…

Questions to explore with your client

• What drew you to it, and what are you hoping it will change?
• Is there physical contact? Was it explained beforehand, and do you feel free to say no or stop at any point?
• Does it involve intense or unusual breathing? Have you been told about the medical conditions for which that is not advised?
• Does it involve fasting, a special diet or 'detox'? Have you discussed this with your doctor?
• Is it a group, retreat or community? How do they respond if someone wants to leave or raises a concern?
• Who runs it, and what training or registration do they hold?
• What actually happens in a session or meeting, and how often?
• What does it cost, and is there pressure to commit to more?
• How do you feel afterwards, in the hours and days that follow?
• Does it fit with, or clash with, the work we do here?

What practitioners of it watch for

• Indefinite courses without review; endings experienced as failure.
• Unexplained injuries; the child avoiding specific adults; the family being told not to watch.
• Parents given long home "sensory" routines that add load to the family or become a battle with the child.
• Overstimulation signs reported after sessions (agitation, shutdown); new fears of equipment or of being touched.
• The child getting different messages about their body or feelings from different professionals; scope creep in either direction.

When to involve someone else

• New or worsening physical symptoms, or advice to stop or change prescribed medication: involve the client's doctor or prescriber.
• Signs of coercion, isolation from family and friends, escalating costs or secrecy: discuss openly and consider safeguarding.
• A crisis or thoughts of suicide: follow your crisis protocol. In the US, call or text 988; in the UK and Ireland, Samaritans on 116 123.
