This study aimed to determine the effect of sensory integration therapy in a child with achondroplasia which is the most common skeletal dysplasia.
Methods: A three year nine months old boy was included in the study. Dunn Sensory Profile was used to determine how the child process sensory information in everyday situations. Change in motor function over time was evaluated with Gross Motor Function Measurement (GMFM-88). Data were collected pre- and post-intervention. Sensory integration therapy and physiotherapy program were provided twice a week, for six months, 45 min for each session. Sensory diet activities were given for home.
Results: Sensory modulation problems were identified in auditory, visual, vestibular, proprioceptive, tactile and multi- sensory processing systems. According to the Sensory Profile modulation problems like tactile defensiveness and gravitational insecurity were decreased from the pre- to post-therapy. Auditory reactions to sounds like horn and/or hoover and sensitivity to light both decreased and concentration time lengthened after the therapy. The child showed better positive change in GMFM scores (from 20,45% to 39,39%).
Conclusion: Sensory integration therapy decreased modulation problems and improved gross motor functions in a child with achondroplasia. While previously reported delays in the development of communication and motor skills, there has been no study in sensory processing children with achondroplasia. To promote social and emotional responses and social participation, intervention programs should include sensory integration therapy in achondroplasia. Our findings need to be supported with long term follow-up researches in wider samples.
