Background: Behavioral and emotional problems in children with Developmental Coordination Disorder (DCD) are well documented. However, the heterogeneity of this group has been largely overlooked. Addressing this gap is important to develop individually-tailored interventions. Aims: Our three aims were to assess: (i) behavioral and emotional problems in children with DCD; (ii) behavioral and emotional problems in subtypes of DCD, and (iii) the context-specificity of these problems (home/school). Methods and procedure: Data were extracted from the medical records of a large sample of 93 children with DCD (79 boys, mean age 8.3) referred to a rehabilitation center. Behavioral and emotional problems were assessed with the Child Behavior Checklist (CBCL) and the Teacher Report Form (TRF). Outcomes and results: Two-third of the children presented with behavioral and emotional problems according to both parents and teachers. The subtypes with generalized motor problems were most affected, while the subtype with gross-motor problems was least affected. Children presented with more problems at home than at school. Conclusion and implications: Given the frequent occurrence of behavioral and emotional problems, clinicians should tailor their interventions to these problems in DCD. Knowledge of subtypes can inform these decisions. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate neuromotor task training (NTT), a recently developed child-centred and task-oriented treatment programme for children with developmental coordination disorder (DCD). A treatment and a non-treatment control group of children with DCD were included. Children were selected if they scored below the 15th centile on the Movement Assessment Battery for Children (MABC). The children in the treatment group were recently referred for physiotherapy (n = 26; 20 males, 6 females; mean age 7y 2mo [SD 1y 3mo]). The parents of the non-treated children were concerned about their children's motor performance and responded to advertisements for free testing (n = 13; 10 males, 3 females; mean age 7y 2mo [SD 2y 1mo]). Before and after nine weekly 30-minute sessions of NTT or at least 9 weeks of no intervention, the MABC and the Test of Gross Motor Development - 2 (TGMD-2) were administered. Therapists reported per session on treatment goals and tasks trained. The results indicate that motor performance does not improve spontaneously and that NTT is effective. During the intervention period, only the treated group improved on the MABC and the TGMD-2. Children improved most on tasks similar to those trained. In older children with poorer motor patterns, NTT's treatment success was higher. The Child Behavior Checklist subscales withdrawn, thought problems, anxious/depressed, and delinquency were determinants of effects on motor patterns. (Contains 5 tables and 1 figure.)

Children with developmental co-ordination disorder ( DCD) face evident motor difficulties in activities of daily living ( ADL). Assessment of their capacity in ADL is essential for diagnosis and intervention, in order to limit the daily consequences of the disorder. The aim of this study is to systematically review potential instruments for standardized and objective assessment of children's capacity in ADL, suited for children with DCD. As a first step, databases of MEDLINE, EMBASE, CINAHL and PsycINFO were searched to identify studies that described instruments with potential for assessment of capacity in ADL. Second, instruments were included for review when two independent reviewers agreed that the instruments (1) are standardized and objective; (2) assess at activity level and comprise items that reflect ADL; and (3) are applicable to school-aged children that can move independently. Out of 1507 publications, 66 publications were selected, describing 39 instruments. Seven of these instruments were found to fulfil the criteria and were included for review: the Bruininks- Oseretsky Test of Motor Performance-2 ( BOT2); the Do- Eat ( Do- Eat); the Movement Assessment Battery for Children-2 ( MABC2); the school- Assessment of Motor and Process Skills (school AMPS); the Tuffts Assessment of Motor Performance ( TAMP); the Test of Gross Motor Development ( TGMD); and the Functional Independence Measure for Children ( WeeFIM). As a third step, for the included instruments, suitability for children with DCD was discussed based on the ADL comprised, ecological validity and other psychometric properties. We concluded that current instruments do not provide comprehensive and ecologically valid assessment of capacity in ADL as required for children with DCD. [ABSTRACT FROM AUTHOR]

Objectives: Observational screening instruments are often used as an effective, economical first step in the identification of children with Developmental Coordination Disorder (DCD). The aim was to investigate the psychometric properties of the Finnish version of the Motor Observation Questionnaire for Teachers (MOQ-T-FI)., Methods: The psychometric properties were tested using two separate samples (S1: age range 6-12, M 9y 5mo, females 101, males 92; S2: age range 6-9, M 7y 7mo, females 404, males 446). Teachers completed the MOQ-T-FI in both samples, and in sample 2 teachers' ratings were compared to student's performance on the Movement Assessment Battery for Children-Second Edition (MABC-2). Internal consistency was investigated by using Cronbach's alpha, predictive validity by receiver operating characteristic (ROC) analysis, concurrent validity by correlation analysis, and construct validity by factor analysis., Results: The MOQ-T-FI behaves consistently with its original Dutch version. The internal consistency was excellent (α=0.97). The bifactor model, with one general factor and two specific factors, fit the data significantly better than the first-order model. The concurrent validity with the MABC-2 was moderate (r=0.37 p<0.001). Sensitivity was 82.5% and specificity 44.5%, respectively., Conclusion: Notwithstanding the low specificity the MOQ-T-FI can be considered as a promising screening tool in the school environment for Finnish children at risk of motor learning problems., (Copyright © 2016 Elsevier B.V.

Background: Children treated for acute lymphoblastic leukemia (ALL) often complain about handwriting problems., Procedure: Using a computerized writing task, we have prospectively studied the processes necessary for the production of handwriting movements in 11 children (5-12 years old) during treatment for ALL. Children were tested at time points closely related to the vincristine administration., Results and Conclusions: Children treated for ALL drew slower, with longer pause durations and increased drawing pressure. Children were able to overcome the problems, except for a consistently increased drawing pressure. This increased drawing pressure may be an attempt of the children to obtain sufficient kinesthetic information and thus can be seen as an adequate adaptation mechanism in case of peripheral neuropathy due to the neurotoxic effects of vincristine. However, neurotoxic effects of other cytostatic drugs cannot be excluded., (Copyright 2001 Wiley-Liss, Inc.)

The aim of this review was to investigate the selection criteria used in the past in studies of children with developmental motor problems (excluding those suffering from neurological dysfunctions such as cerebral palsy, muscular dystrophy, etc.). We therefore conducted an extensive analysis of 176 publications. First, an overview of the main characteristics of these studies (terminology, population, type and purpose) and the selection criteria that are reported in these publications are presented. Following this, the DSM-IV selection criteria for developmental coordination disorder (DCD) are contrasted with the selection criteria reported in 41 publications that have used this terminology to classify the children. The results of this comparison show that the inclusion criteria are largely followed, albeit with little consistency concerning selection instruments and quantitative cut-offs, while adherence to the exclusion criteria is not common practice. Strengths and weaknesses of the DSM-IV criteria, complementary to the previous discussion by Henderson and Barnett in the HMS special issue on DCD in 1998 on this same topic, are discussed. The results of the review also show that many studies have used additional selection criteria related to the specific research questions of the study concerned. In the broader context of clinical practice as well as basic research, the latter result suggests the usefulness of a distinction between Clinical Diagnostic Criteria and Research Diagnostic Criteria. This distinction helps to develop a unifying view on the use of diagnostic criteria for research and clinical practice. We conclude with a number of recommendations concerning the selection criteria for children with DCD.

Neurophysiological functioning was studied prospectively in children treated for acute lymphoblastic leukaemia with a low dose vincristine regime (8 x 1.5 mg/m2/dose), to obtain more insight into vincristine neuropathy. A WHO neurotoxicity score was estimated and vibration sense and electrophysiological measurements were taken at standardized times during vincristine treatment. The WHO neurotoxicity score showed decreased or disappearance of Achilles tendon reflexes, and mild sensory disturbances, but a grade 3-4 neurotoxicity was not demonstrated by any of the children. Vibration perception thresholds increased progressively during treatment and amplitudes of action potentials of peroneal and sensory ulnar and median nerves decreased, whereas nerve conduction velocities stayed unchanged. Both vibration perception thresholds and the electrophysiological findings hardly exceeded the limits of normality. We conclude that children treated for acute lymphoblastic leukaemia with a low dose vincristine regimen have mild axonal neuropathy which may be responsible for the motor problems in these children.

Motor skills were investigated in 18 children 2 years after treatment for acute lymphoblastic leukemia (ALL). Gross and fine motor functioning were examined with the Movement Assessment Battery for Children. Handwriting as a specific fine motor skill was studied with a computerized writing task. We conclude that 2 years after cessation of treatment motor problems in ALL survivors were still present. Dysfunctions were mainly pronounced in handwriting and fine motor skills.
