Abstract
Due to the importance of rehabilitation among children with special learning disabilities, the aim of this study was to evaluate the effect of brain Gym on suppression of theta/alpha ratio and working memory of students aged 8 to 12 years with dyslexia or dysgraphia. This research was a quasi-experimental study with a pre-test and post-test design with a control group. The population of this study included all girls and boys with reading or writing disorders referring to special centers for learning disabilities in Kermanshah. The convenience sampling methods were used. For this purpose, according to the inclusion and exclusion criteria, 20 students aged 8 to 12 years were selected and randomly allocated into two groups of 10 people. The experimental group were received brain Gym intervention for 20 sessions of 20 minutes over 10 weeks. In order to record the brain waves of the participants, a dual-channel neurofeedback device was used. Moreover, the Wechsler memory software was used to measure their active memory. To analyze the data, univariate one-way covariance analysis and multivariate one-way covariance analysis were used using SPSS software version 26. The results showed that the ratio of theta waves to alpha in the experimental group was significantly reduced and active memory span in the experimental group was significantly increased compared to the control group (P < .05). The findings of this study indicated that brain exercise can significantly suppress the ratio of theta waves to alpha and also improve working memory among children with special learning disabilities. The findings confirm the neurological evidence for the positive effect of the brain Gym intervention on the modulation of brain waves and working memory in children with dyslexia or dysgraphia. |

Abstract
Dysgraphia is one of the common symptoms of specific learning disorders. children with dysgraphia have several cognitive problems. This research was conducted with the aim of investigating the effectiveness of HAMRAH cognitive rehabilitation package on improving executive functions (working memory and response inhibition) in children with dysgraphia. The present research was semi-experimental in the form of pre-test-post-test with a control group. The statistical population of the research was students with dysgraphia who referred to education counseling centers in Kermanshah city in 1401. Among them, 40 people (initially 20 people in the experimental group and 20 people in the control group, but one of the control group was removed by the end of the experiment) who were willing to cooperate and were also available were selected and then randomly divided into experimental and control group. Then, in both groups, the pre-test was implemented, and after that, the experimental group received 12 intervention sessions of the HAMRAH cognitive rehabilitation package, but there was no intervention for the control group. Then, a post-test was performed for both groups. The data were analyzed using covariance. The results showed that the Hamrah cognitive rehabilitation package has an effect on improving working memory and response inhibition in children with dysgraphia (P<0.01). It is suggested that the HAMRAH cognitive rehabilitation package be used in medical centers by mental health specialists, along with other treatment methods, in order to improve working memory and response inhibition for children with dysgraphia

Abstract
children with dysgraphia have several visual perception. This research was conducted with the aim of investigating the effectiveness of HAMRAH cognitive rehabilitation package on improving visual perception in children with dysgraphia. A semi-experimental in the form of pretest-posttest control group design was used. 40 primary school students with dysgraphia who referred to counseling centers in Kermanshah city in the academic year 2022/2023 were selected. Among them, 40 who were willing to cooperate and were also available according to the entry criteria (having at least three components among the diagnostic criteria of dysgraphia, student and parent satisfaction) and withdrawal (being under other interventions) and after obtaining informed consent, they were randomly selected and and randomly divided into experimental and control groups. After performing the pre-test on both groups, a 12-session HAMRAH cognitive rehabilitation package was performed on the experimental group. Then both groups received the post-test. The data were analyzed using covariance. The results showed that the Hamrah cognitive rehabilitation package has an effect on improving visual perception and its components (spatial communication, spatial perception and shape stability) in children with dysgraphia (P<0.01). However, there was no significant effect on the components of shape-background recognition and motor-visual coordination. It can be concluded that the Hamrah cognitive rehabilitation package can be used as a single treatment or along in combination psychological therapies for students with dysgraphia.
