Introduction

Sensory Processing Dysfunction (SPD) is one of the commonest co-morbid condition occurs in children with Autism Spectrum Disorder (ASD) and it has been widely reported in literature, however studies done to evaluate these problems in Indian subcontinent are very limited. A cross sectional study was done to find the proportion of children with ASD having sensory problems and its association with behavioral problems and adaptive behaviors.

Methods

Sensory problems, behavioral problems and adaptive behavior were assessed in 100 children diagnosed with ASD in 3 to 12 years age.Descriptive data analysis was done to identify prevalence of sensory problems and its association with behavioral problems and adaptive behaviors.

Results

88% of the sample showed some degree of sensory processing abnormalities with low sensory registration (72%) being the commonest, followed by abnormal touch processing (67%) and abnormal movement processing (57%). Sensory avoiding pattern, abnormal body position and oral processing were significantly associated with internalizing problem behaviors whereas, seeking, avoiding pattern and abnormal movement processing were significantly associated with externalizing problem behaviors. Sensory registration and abnormal Touch Processing were associated with low scores in adaptive functioning.

Conclusion

This study shows that the prevalence of SPD in children with ASD is similar to findings of previously published studies. In view of high prevalence of sensory problems and their significant association with problem behaviors and activities of daily living, sensory problems should be assessed separately in children with ASD since they may require specific modifications in treatment.
