This paper describes a research project using a single-case experimental design (A-B-A), which aimed to explore the impact of sensory integration therapy (SIT) on level of engagement and maladaptive behaviour (measured through timed scores) and function (using Goal Attainment Scaling, GAS) for five learning disabled adults with tactile sensory modulation disorder.
Each phase lasted 4 weeks and consisted of 24 measurements in total. Individually tailored SIT was given twice weekly for 4 weeks during the intervention phase (B), immediately prior to each individual’s participation in his or her prescribed horticulture task. The changes between phases in engagement, maladaptive behaviours and function scores, measured as the difference between baselines and intervention, were analysed visually and statistically for each participant.
The intervention produced significant improvements in engagement for participant four, with a highly significant deterioration in scores for all five participants on withdrawal of SIT. All the participants’ maladaptive behaviour decreased significantly on the introduction of SIT. Although there was no significant change to GAS scores for four participants, participant four’s score improved significantly with SIT. The withdrawal of SIT resulted in a highly significant deterioration in GAS scores for participants one, two, four and five. This study may be the first to suggest that SIT is effective in improving functional performance in adults with a learning disability with a tactile sensory modulation disorder.
Looking forward to following this new organisation, who appear to have some amazing resources from my first drop onto their website today.

So often people ask about DCD and sensory integration, and often the reply given is a quote from Bundy Lane
A recent study concluded that
“Our findings indicate that sensory processing abnormalities may contribute to the pathophysiology of DCD, suggesting the importance of assessing sensory processing functions in children with DCD.”

“A little while ago, two mums approached me and both asked about assessments for their children. Both were young adults, academically highly able and struggling with their self-organisation and motor skills.
Both young people consented to an assessment and completed, through self-report, the Adult/ Adolescent Sensory History (AASH) questionnaire. They were also assessed with the Sensory Integration and Praxis Test (SIPT). The SIPT is a standardised assessment with normative data for ages 4 through 8 years, 11 months. On this particular assessment tool, sensory integration and processing skills scores plateau at around this age, though the test is still informative for people beyond this age, who should have achieved.
The young lady assessed has a diagnosis of social anxiety and has low confidence, while the young man is quite a confident character. She has a history of bumps, trips and spills, and will tell anecdotes of these with great humour; while he prefers to focus on what he does well in conversation.
I love the AASH, the reports it gives highlight each sensory system, differentiate between discrimination and modulation difficulties and addresses motor planning, sequencing and social/ emotional aspects of sensory integration and processing needs.
It uses clear, non-patronising language and activities appropriate to adults and adolescents. It shows up really clearly a person’s (or their caregiver’s as necessary) perception of their sensory integration and processing needs and how these affect their day to day life. In this instance, the young lady highlighted many sensory processing needs.
The young man reported almost no difficulties, his only score in the primary sensory systems section was mild proprioceptive difficulties. When questioned as to the accuracy of his answers, he tended to reply “well, nobody likes that, do they?”
Having scored the AASH checklists, I completed a SIPT with each person. The SIPT is a battery of 17 tests which assess a person’s sensory integration and processing including perceptual-motor skills through tasks with standardised administration and normative data against which to compare an individuals test results. Guess which person showed more significant difficulties in the direct assessment?
On the SIPT assessment scores between -1 and +1 standard deviation are considered typical, above +1 are strengths and scores below -1 are of clinical significance and require support and will benefit from direct intervention.
The exception to this being Post Rotatory Nystagmus in which a low (below -1) or high score (above +1) indicates significant difficulty inhibiting response to vestibular information and often relates to a low Standing and Walking Balance score.
Here are the young lady’s SIPT results:
Definite movement, balance and body awareness difficulties but also some areas of significant strength, particularly around her visual skills and imitation, which she uses to compensate for her body awareness difficulties.
Here’s the young man’s chart:
Strong visual skills, compensating for significant challenges in the other areas.
This experience taught me so much. From the AASH scores, I was expecting the young lady to have much more problems in the SIPT than the young man, their conversation about their lifestyles confirmed this expectation. Still, then the assessment showed so clearly how much of that was related to confidence.
An evaluation based solely on checklists is not enough. It tells you what a person perceives to be their difficulties, guides the direction of evaluation and adds experiential evidence to the overall assessment.
A good questionnaire is evidence-based and norm-referenced, but it always needs to be triangulated with direct observation and where possible structured and standardised assessment. These tools can tell you so much about the respondent’s confidence and resilience and what they find easy or difficult in day to day life. But I have learned it is a mistake to rely upon one alone when assessing somebody’s sensory integration and processing skills and needs”.
