Children with Developmental Coordination Disorder (DCD) have impairments in gross and fine motor skills consequently limit their participation in school activities. The aim of this study was firstly to evaluate motor coordination performance of children with DCD in manual dexterity, hand-eye coordination and balance skills, and secondly, to compare the motor coordination performance between children with DCD and age-matched children without DCD. A total of 47 children with DCD (32 boys, 15 girls) and 16 children without DCD (15 boys, 1 girl) aged between 7 to 10 years old participated in this study. They were recruited from integrative special education classes from six selected primary schools within Klang Valley. The Movement Assessment Battery for Children-2 (MABC-2) evaluated their motor coordination performance. Group differences on the MABC-2 subtest scores and total test score were analysed using independent t-test. Cohen’s d was calculated to obtain the effect size of clinical differences. Children with DCD showed significantly lower score in manual dexterity (p=0.001), aiming and catching (p=0.001), balance test (p=0.001) and total test score (p=0.001) compared to the children without DCD. Effect sizes on manual dexterity (d=0.52), balance (d=0.68), and total test score (d=0.73) indicated moderate clinical differences between the two groups. In conclusion, children with DCD showed deficits in both gross and fine motor skills performance based on the MABC-2 subtests and total test score, in comparison with children without DCD. School-based rehabilitation to improve gross and fine motor problems among the children is warranted.

OBJECTIVE: To assess the clinical features of children with developmental coordination disorder (DCD) and the effects of occupational therapy. METHOD: Seventeen children were diagnosed with DCD using by Bruininks-Osteretsky test of motor proficiency (BOTMP). To investigate the clinical features, neurological examinations such as soft neurological signs, speech evaluation, cognitive assessment, and psychiatric evaluation were performed on the 17 participants. Among the participants, 8 children had occupational therapy. BOTMP and cognitive function were evaluated both prior to and 6 months after the intervention. RESULTS: Children with DCD showed various soft neurological signs and co-morbidities such as attention-deficit hyperactivity disorder (ADHD), developmental language disorder, and emotional problems. The cognitive assessment revealed disproportionately low performance IQ for all subjects. After occupational therapy, scores for BOTMP and performance IQ increased significantly. CONCLUSION: The clinical features of DCD are heterogeneous and occupational therapy focused on motor proficiency was effective. This study supports raising interest in and attention on children with motor coordination difficulties.

OBJECTIVES: The objective of this study was to investigate the effect of pharmacological treatments for attention-deficit hyperactivity disorder (ADHD) on motor coordination, using the Developmental Coordination Disorder Questionnaire (DCDQ). METHODS: The participants were recruited from April 2015 to November 2016 from the Department of Psychiatry of Asan Medical Center and were treated for 3 months with methylphenidate or atomoxetine. The illness severity at baseline and 3 months were scored using the ADHD Rating Scale (ARS), Clinical Global Impression-Severity Scale (CGI-S) and/or Clinical Global Impression-Improvement Scale (CGI-I). A total of 39 children with ADHD (age 8.0±1.4 years, 36 boys) completed the Advanced Test of Attention (ATA) and their parents completed the DCDQ at baseline and 3 months. The paired t-test, mixed between-within analysis of variance and correlation analysis were used. RESULTS: The CGI-S (p<0.001), ARS (p<0.001), and fine motor/hand writing (p=0.005) on the DCDQ were significantly changed between pre-treatment and post-treatment. When the participants were divided into those who were suspected of having developmental coordination disorder (DCD) (n=23) and those who probably did not (n=16), the control during movement, fine motor/hand writing and general coordination scores on the DCDQ showed the main effects for group (p<0.001, p<0.001 and p<0.001, respectively). The fine motor/hand writing on the DCDQ has a significant main effect for time [F(1,37)=7.31, p=0.010, η2=0.405] and the interaction effect between group and time was also significant [F(1,37)=4.63, p=0.038, η2=0.111]. The baseline visual commission error on the ATA is significantly correlated with the changes in the DCDQ total scores (r=0.330, p=0.040). CONCLUSION: Our results provide preliminary evidence that pharmacological treatment for ADHD improves not only the core symptoms of ADHD, but also the motor coordination. Further studies are needed to confirm the effect of the pharmacological treatment for ADHD on the motor coordination.

Development in motor skills and abnormal movement patterns in developing child are clearly observed and easily identified by the parents. Motor delay and movement disorder are common presentations for children with developmental disorders. Therefore, assessment for motor development and movement disorder become the major developmental focus of early in life. Physical examination has been considered as a key element for identifying developmental motor disorder. Traditionally, development of tone, primitive reflexes, postural reaction and motor milestone are commonly used as the evaluation tools for early identification of children at high risk for developmental disorder. Recently the assessment of the quality of general movements was introduced as a new form of neuromotor assessment of young infant. Therefore, clinical usefulness of the assessments for detecting neurological dysfunction was briefly reviewed in this paper. As well, there are a lot of movement disorders shown in child. The movement disorders can be separated into transient, paroxysmal and chronic ones according to their evolution. Since the knowledge of the movement disorders in each category enables us to understand the evolution of movement disorders, avoid unnecessary tests and treatments, and also give the proper information to the parents, the movement disorders were briefly reviewed in this paper.

Motor disorders in childhood include tic disorder, developmental coordination disorder, and stereotypic movement disorder. A tic is a sudden, rapid, repetitive and nonrhythmic movement (motor tics) or phonic production (phonic or vocal tics) that can occur at any part of the body. Developmental coordination disorder (DCD) is characterized by marked impairment in the acquisition and performance of motor skills. Stereotypic movement disorder is a common childhood disorder which repetitive, hard to control, aimless motor activity interrupts everyday life or causes self-infliction of a child. Despite increased attention and the growing scientific knowledge about motor disorders, there are limitations in our understanding and knowledge about the pathogenesis and the management of the disorders. Motor disorders can itself be the primary diagnosis, or can be secondarily diagnosed caused by other disorders, and accompany many neuropsychiatric disorders such as autism and attention deficit hyperactivity disorder (ADHD), which in turn impairs proper learning and socializing of the children with motor disorders. Therefore comprehensive medical history taking, continuous observation of the changes in symptoms, and systematic assessment considering the child's developmental stage and current adaptive capacity are needed. Behavioral therapy and pharmacological therapy are the two most often mentioned treatments of motor disorders.

OBJECTIVES: This study explored the clinical differences in attention-deficit hyperactivity disorder (ADHD) patients with and without developmental coordination disorder (DCD). METHODS: Participants were 49 children and adolescents with ages between 6 and 18 years. These subjects were placed into 2 groups: ADHD without DCD (24) and ADHD with DCD (25). We used several evaluation tools on both groups: the Affective Disorders and Schizophrenia-Present and Lifetime Version- Korean Version (K-SADS-PL), Wechsler Intelligence Scale for Children-III (WISC-IIII), Child Behavior Check List (CBCL), Korean Personality Rating Scale for Children (K-PRC), and Bruininks-Osretsky Test of Motor (BOT-2). RESULTS: Patients with both ADHD and DCD had a lower performance intelligence quotient and more internal and external behavioral symptoms than patients with ADHD but not DCD. It is possible that patients with ADHD and motor coordination problems should be noticed earlier and given intensive treatment.

OBJECTIVETo analyze the comorbidities in patients with cerebral palsy (CP) from two perspectives as neurologic subtype and gross motor functions, and find their correlations.

METHODSChildren with cerebral palsy treated in the rehabilitation center from January 2007 to June 2009 received the following examinations: intelligence capacity test, ophthalmologic consultation, language-speech test, brainstem auditory evoked potential and electroencephalogram. They were stratified according to both neurologic subtype and gross motor functions to detect the occurrence of comorbidities.

RESULTSOf all the 354 cases, 166 (46.89%) had mental retardation, 15 (4.24%) auditory limitations, 138 (38.98%) visual disorder, 216 (61.02%) language-speech disorder and 82 (23.16%) epilepsy. The frequency of individual comorbidities were distributed disproportionately between the different neurologic subtypes. Correlation analysis showed that there was a significant correlation between the spastic diplegia and the visual disorder (correlation coefficient = 0.26), between spastic hemiplegia and epilepsy (correlation coefficient = 0.17), between spastic quadriplegia and epilepsy and mental retardation (the correlation coefficient was 0.38 and 0.11, respectively) and between both dyskinetic and mixed children and language-speech disorder (the correlation coefficient was 0.24 and 0.27, respectively). The frequency of individual comorbidities was distributed disproportionately between the different neurologic subtypes and between the different GMFCS levels (P < 0.05), except for the frequency of visual disorders (chi(2) = 1.90, P > 0.05); and with the increase of the GMFCS levels, the burden of the comorbidities were more heavy and the incidence of the comorbidities was higher. Multi-comorbidities were relatively infrequently encountered in those with spastic hemiplegic or spastic diplegic children or patients whose GMFCS levels were I-III, while these entities occurred at a frequent level for those with spastic quadriplegic, dyskinetic, or mixed or children whose GMFCS levels were IV and V, and the differences were significant (P < 0.05). The mean GMFCS levels of children with spastic quadriplegic, dyskinetic or mixed CP were higher than level III, most of them had no ability of ambulation;while the mean GMFCS levels of spastic hemiplegic or spastic diplegic children were below level III, most of them could walk independently.

CONCLUSIONSThere are correlations between the occurrence of the comorbidities such as mental retardation, auditory or visual impairments, language-speech disorders, epilepsy and the cerebral palsy subtype and the gross motor function levels. Clinicians should have a full recognition of these comorbidities, and we should have a cooperation between the different subjects to have an overall evaluation and rehabilitation and to improve the prognosis.
