Background and Objective: The obesity and overweight in the children of many developing countries have dramatically increased. Obesity is associated with numerous health problems. While children spend a significant amount of their time in school daily, the various aspects of children school-life such as academic achievement, social skills and attendance, can be affected by obesity and overweight. This study was done to determine the correlation between obesity and overweight with attention dificit in elementary school girls. Materials and Methods: This descriptive-cross sectional study was carried out on 300 girls student of 7-11 years old, in elementary schools in capital city of east Azarbijan cocated North-West of Iran in 2007. The samples selected based on body mass index and were classified by random sampling in three groups including, normal group, overweight group and obese group. The data, collected by child behavior check list (CBCL). The CBCL have 113 iteams, 9 iteams of them were designed for determination of attention dificit in children. The behaviors were scored on a 3-point ranging scale. SPSS-11.5 software and ANOVA statistical test were used to analyse the data. Results: The results showed that overweight group had greater scores in attention dificit scale than other groups and revealed a significant correlation between obesity-over weight and attention dificit (r=0.177, P<0.05). Conclusion: This study indicated a significant correlation between obesity and attention dificit. Prevention of obesity as a first step for prevention of behavioral problems, seems to be essentieal. The treatment of obesity may be a matter of dealing with behavioral problems in children.

Background and Objective: Attention deficit hyperactivity disorder (ADHD) is a development nervous disorder that it is usually caused by a defect in the executive functions of the brain and reduces the amount of attention, accuracy, and increased mobility and impulsive behaviors in the individual. This study was performed to determine the effectiveness of cognitive rehabilitation and cognitive rehabilitation after drug therapy on the executive functions of brains of childrens with attention deficit hyperactivity disorder.
Methods: In this clinical trial study, 45 children with ADHD were randomly divided into three groups including one control and two intervention groups, were monitored by the education counseling center. Intervention group one (cognitive rehabilitation) and intervention group two (cognitive rehabilitation after medication) were received therapeutic intervention for 12 sessions of 45 minutes, twice a week. No intervention was performed for the control group. After the last treatment session, a post-test was performed. The follow-up phase took place 1.5 months after the end of the last intervention session.
Results: The executive functions of the brains of children with cognitive impairment in the cognitive rehabilitation group and the cognitive rehabilitation group after drug therapy showed a significant increase in comparison with the control group (P<0.05). The executive functions of fertilizer after 1.5 months of follow-up in the cognitive rehabilitation group after drug therapy were higher than in the cognitive rehabilitation group (P<0.05).
Conclusion: Cognitive rehabilitation therapy after drug therapy was more effective in treating increased executive functions of the brain in children with cognitive impairment than cognitive rehabilitation therapy alone.

Background and Objective: Children with ADHD suffer from motor impairment in addition to behavioral problems (hyperactivity/impulsivity, attention deficit).The cerebellum receives data from visual, vestibular and somato- sensory systems.This study was done to determine the correlation between kinetic parameters of balance performance and behavioral symptoms in children with attention-deficit/hyperactivity disorder.
Methods: This case - control study was performed on 15 children with ADHD (9.21±0.69 year) and 15 healthy children (9.27±0.75 year). Kinetic parameter of balance evaluated using sensory organization test (SOT) in different sensory conditions including visual, somatosensory and vestibular by Neurocom. Conner’s questionnaire used to assess hyperactivity and attention deficit in addition to a psychologist.
Results: Dynamic balance score in ADHD children was significantly lower in compare to controls (p<0.05). Children with ADHD had kinetic parameters of balance performance abnormality in compare to controls. There was a significant correlation between sensory contribution and hyperactivity in children with ADHD (P<0.05).
Conclusion: Children with ADHD suffer from balance dysfunction which is a result of sensory integration and attention deficit. The sensory systems analysis showed that vestibular system, partially somatosensory dysfunction is the most important factor in balance disorder in children with ADHD.

Background and Objective: Anterior cruciate ligament (ACL) injury is one of the most serious knee injuries and it happens frequently during sports activities. Appropriate muscle activity is essential to provide joint stability and prevention of ACL injury. This study was performed to determine the effect of external focus instructions and functional training on basketball knee stabilization muscle activity timing.
Methods: This clinical trial study was performed on 48 healthy male basketball players of the Iranian Provincial League in the age range of 19-25 years. The basketball players were randomly divided into 3 groups of 16 people including control group, functional training group with feedback and group without feedback. The timing of the onset of electrical activity in the quadriceps, hamstrings, and Gluteus medius muscles of individuals before and after eight weeks in the single-leg landing task was examined by electromyography.
Results: There was a significant difference between the groups at the onset of Biceps Femoris, Gluteus Maximus, Gluteus Medius, Vastus Medialis, Vastus Lateralis, Rectus Femoris and Medial Hamstring muscles. There was a significant decrease in muscle activity onset between functional groups with and without feedback in compared to control group (P<0.05). There was no significant difference between the training groups at the beginning of the activity of the mentioned muscles.
Conclusion: Functional basketball training with and without feedback can optimize the activity time of the knee stabilizing muscles, during exercises such as jump-landing, increase the stability of the knee joint and possibly reduce ACL injury in athletes.

Background and Objective: Chronic hypertrophy of tonsils and adenoids is the most prevalent cause of sleep apnea in children, leading to multiple behavioral disorders. Attention deficit hyperactivity disorder (ADHD) is a heterogeneous disorder caused by adverse biological, social and psychological conditions. This study aimed to evaluate the effect of adenotonsillectomy on ADHD symptoms in children with adenotonsillar hypertrophy before and six months after the surgery.
Methods: This descriptive-analytical study was performed on 37 children with adenoid hypertrophy in Gorgan, north of Iran during 2018. The data gathering tool was a two-part questionnaire; the first part contained personal data (age, gender), and the second part included the strengths and difficulties checklist. Patients were placed in three groups of hyperactivity, inattention and impulsivity based on 18 criteria of Diagnostic and Statistical manual of Mental disorders. The questionnaires were completed directly by the project performers. Information was collected from the parents. The strengths and difficulties questionnaire (SDQ) was used to assess children before and six months after the adenotonsillectomy surgery.
Results: The average and standard deviation of scores in subscales of emotional symptoms, conduct problems, hyperactivity-inattention, peer relationship problems and prosocial behavior were improved, also a significant difference was observed between SDQ scores before and after adenotonsillectomy (P<0.05).
Conclusion: Adenotonsillectomy can significantly reduce the SDQ score. Therefore, in children with hyperactivity, a medical disorder such as adenoid hypertrophy can cause the onset, exacerbation and persistence of the disease. Proper treatment can be a major factor in controlling the severity of symptoms and even in improving the patient’s recovery.
