The aim of this study is to examine the sensory and functional effects of sensory integration therapy in children with dyslexia according to the Model of Human Occupation (MOHO).

35 participant (17 intervention, 18 control, aged 8.7;8.5 years) diagnosed with dyslexia were included in the study. In the special education and rehabilitation centers, where they were followed, both groups received special individual training sessions twice a week for eight weeks, and in addition to the intervention group, sensory integration therapy was applied once a week for eight weeks (45 minutes therapy, 15 minutes family briefing - 60 minutes in total). Sensory Profile Test was used for sensory processing evaluation and SCOPE (The Short Child Occupational Profile) for occupational performance analysis. Intervention results and intergroup scores were analyzed using the Wilcoxon Paired Two Sample Test and the Mann Whitney-U test.

This study aims to examine the effect of sensory integration therapy on sensory modulation and daily functional performance in children with dyslexia, according to the occupational therapy model MOHO.

The study was carried out in Biruni University Sensory Integration Unit on 35 participants ( intervention group:17, aged 8,7±0,85 years; control group:18, aged 8,5±1,1 years) with dyslexia.

According to the results of the analysis made in the R program, it was calculated that the sample volume should be 35 at 80% Power.

The investigators talked about the study with a special education and rehabilitation center. They will briefly ask the families of children with dyslexia who meet the inclusion criteria, during their routine education/therapy sessions, whether they might be interested in taking part in the study or not. Following this, the informed consent form was signed by the parents who accepted and were willing to volunteer to take part in the study, since the individuals participating in the study were under the age of 18.

Children between the ages of 6 and 10 years who were diagnosed with dyslexia by a psychiatrist according to DSM-V criteria were included in the study. Children with any secondary diagnosis were excluded from the study. 40 participants were randomly divided into 20 control and 20 intervention groups using a random number table.

Children in the intervention group were included in sensory integration therapy sessions at Biruni University Sensory Integration Unit for eight weeks, one session a week, 45 minutes sessions, and 15 minutes of family information. Both groups continued special education sessions in special education and rehabilitation centers twice a week for eight weeks. Three participants from the intervention group and two participants from the control group left the study.

The socio-demographic data was collected and recorded, including age, parentage, gender, health status. During the evaluation phase, the Sensory Profile test and the SCOPE (The Short Child Occupational Profile) was applied to both groups.

Inclusion Criteria:

• Were between the ages of 6 and 10 years
• Diagnosed with dyslexia by a psychiatrist according to DSM-V criteria

Exclusion Criteria:

• Had any secondary diagnosis
