Effect of Swiss Ball Stabilization Training on Trunk Control, Abdominal Muscle Thickness, Balance, and Motor Skills of Children With Spastic Cerebral Palsy: A Randomized, Superiority Trial

OBJECTIVES

To compare the effects of Swiss ball stabilization training (SBST) and stable surface stabilization training (SSST) on the trunk control, abdominal muscle thickness, balance, and motor skills of children with spastic cerebral palsy (CWSCP).

DESIGN

Single-blind, randomized superiority trial.

SETTING

General Community and Referral Center.

PARTICIPANTS

Thirty CWSCP, aged 6-12 years, with Gross Motor Function Classification System levels I-III were randomly assigned to the SBST and SSST groups (N=30).

INTERVENTIONS

The participants were randomized to receive either SBST or SSST for 5 weeks, 3 days a week.

OUTCOME MEASURES

The Trunk Control Measurement Scale (TCMS), abdominal muscle thickness, Pediatric Balance Scale (PBS), standing and walking sections of Gross Motor Function Measure (GMFM-88), and mobility section of the Pediatric Evaluation of Disability Inventory (PEDI) were assessed.

RESULTS

After 5 weeks of the intervention and 9 weeks of follow-up, the SBST group showed statistically significant improvements in the TCMS, GMFM-88, PEDI, thickness of the internal oblique muscle at rest and contraction, and thickness of the transverse abdominis muscle at rest and contraction compared with the SSST group (P<.0001). Contrarily, the thickness of the external oblique muscle increased statistically significantly in the SSST group compared with the SBST group after 5 weeks of the intervention and 9 weeks of follow-up both at rest (P<.0001 and P=.0001, respectively) and contraction (P=.015 and P=.017, respectively). No statistically significant difference was found between the groups regarding the PBS score after 5 weeks of intervention.

CONCLUSION

The SBST could improve the trunk control, balance, and motor skills of CWSCP and increase the thickness of local abdominal muscles. Also, SBST was more effective than SSST for CWSCP.

Do Girls Have an Advantage Compared to Boys When Their Motor Skills Are Tested Using the Movement Assessment Battery for Children, 2nd Edition?

This study aims to investigate sex-related differences in raw item scores on the Movement Assessment Battery for Children, 2nd Edition (MABC-2) in a large data set collected in different regions across the world, seeking to unravel whether there is an interaction effect between sex and the origin of the sample (European versus African). In this retrospective study, a secondary analysis was performed on anonymized data of 7654 children with a mean age of 8.6 (range 3 to 16; SD: 3.4), 50.0% of whom were boys. Since country-specific norms were not available for all samples, the raw scores per age band (AB) were used for analysis. Our results clearly show that in all age bands sex-related differences are present. In AB1 and AB2, girls score better on most manual dexterity and balance items, but not aiming and catching items, whereas in AB3 the differences seem to diminish. Especially in the European sample, girls outperform boys in manual dexterity and balance items, whereas in the African sample these differences are less marked. In conclusion, separate norms for boys and girls are needed in addition to separate norms for geographical regions.

Stretch marks: a visible expression of connective's involvement in autism spectrum disorders

In autism spectrum disorders (ASDs) in the pediatric population, skin manifestations are generally attributable to the concomitance of allergic forms or to accidental, self-inflicted or abusive lesions. However, clinical evidence has highlighted the presence of an increasing number of abdominal stretch marks, probably caused by the increase in the number of obesity cases in the pediatric population, in general, and therefore also among children with ASD. Stretch marks are often attributed to obesity, as they have an incidence of more than 50% in obese individuals. In the first part of this article we hypothesized that in addition to obesity there are other factors, such as a structural alteration on the skin in people with ASD, which can contribute/aggravate the phenomenon of stretch marks. Despite the high frequency with which stretch marks are found in children with ASD, this aspect has never been studied, the structure of the skin of children with ASD is not known. Furthermore, it is not known whether this structure is different from that of subjects without ASD. In the second part of the article, we hypothesized the mechanisms of the negative impact of simple abdominal stretch marks on the symptomatic picture of children with ASD. The presence of stretch marks, altered tactile perception, altered sensitivity to clothing fabrics can be a combination that influences development and determines negative consequences in the neurological picture of a child with ASD, as it is already known that the altered sensory perception in children with ASD contributes to the deterioration of social behavior. Furthermore, the presence of stretch marks may play a role in the postural and motor defects of children with ASD.

Table Tennis, as a Method of Sensorimotor Training, Induces Haptic and Motor Gains in Children With a Probable Developmental Coordination Disorder

This study examined whether table tennis as a method of sensorimotor training improves haptic and motor function and to what extent haptic function gain correlates with changes in motor ability in children with probable developmental coordination disorder (pDCD). Children with pDCD were randomly assigned to the table tennis and nontraining control groups. The children in the table tennis group received 36 sessions of table tennis training, including ball balancing, hitting the ball against the wall, strokes, and serving. Haptic sensitivity, acuity, and motor function domains were measured. The results showed a 41.5% improvement in haptic sensitivity in children exposed to table tennis training compared with 2.8% in those without training. This improved haptic sensitivity significantly correlated with motor function gain, suggesting that somatosensory gains occur simultaneously with changes in motor function in children with pDCD. This novel upper limb motor training approach may be an interesting method of sensorimotor training in neurological rehabilitation in children with pDCD.

Tai chi-muscle power training for children with developmental coordination disorder: a randomized controlled trial

This study compared the effectiveness of tai chi (TC) muscle power training (MPT), TC alone, MPT alone, and no training for improving the limits of stability (LOS) and motor and leg muscular performance and decreasing falls in children with developmental coordination disorder (DCD). One hundred and twenty-one children with DCD were randomly assigned to the TC-MPT, TC, MPT, or control group. The three intervention groups received TC-MPT, TC, or MPT three times per week for 3 months. Measurements were taken before and after the intervention period. The primary outcomes were the LOS completion time and dynamic LOS scores. The secondary outcomes included the Movement Assessment Battery for Children-Second Edition total test score and percentile rank, knee muscle peak force and time to peak force, and the number of falls. None of the interventions affected the LOS test scores. Improvements in the peak forces of the knee extensors and flexors were demonstrated in the TC (p = 0.006) and MPT groups (p = 0.032), respectively. The number of falls also decreased in these two groups (p < 0.001). Thus, clinicians may prescribe TC or MPT for children with DCD to increase their knee muscle strength and reduce their risk of falls.

Effects of neuromuscular training on postural control of children with intellectual disability and developmental coordination disorders : Neuromuscular training and postural control

Background

Children with Intellectual disabilities who suffer from developmental coordination disorder represent insignificant physical fitness, strength, and balance. The prime objective of this research is to explore the impact of eight weeks of neuromuscular (combined physio-hemsball) training on postural control and balance of students with intellectual disabilities suffering from developmental coordination disorder.

Methods

The present study was a prospective randomized clinical trial with a pretest–posttest design. The statistical population consisted of boys with intellectual disabilities, suffering from developmental coordination disorder randomly divided into two groups: the experimental group (n = 15) and the control group (n = 15). informed consent was obtained from all participants’ parents. Parents completed developmental coordination disorder questionnaires. Tests (Balance Error Scoring System, Y-Balance, timed Get Up & Go) were used to determine postural control, dynamic balance, and functional balance of subjects. The experimental group performed a combined physio-hemsball training for 8 weeks. Ethical considerations were observed according to the Helsinki Declaration and the CONSORT guidelines and regulations were followed to report this study.

Results

Results showed that combined physio-hemsball training for 8 weeks can greatly improve postural control and dynamic and postural balance among students with intellectual disabilities suffering from developmental coordination disorder.

Conclusions

According to the results, instructors can use this type of training to improve postural control and balance in boys with intellectual disabilities enduring developmental coordination disorders.

Effects of modified pilates on trunk, postural control, gait and balance in children with cerebral palsy: a single-blinded randomized controlled study

OBJECTIVE

This study aimed to determine the effects of modified pilates exercises (MPE) and neurodevelopmental therapy (NDT) on trunk, postural control, gait, and balance in children with cerebral palsy (CP).

METHODS

18 children with CP between gross motor function classification system (GMFCS) I and III were randomized into two groups as study (Group A, MPE) and control (Group B, NDT). Physiotherapy (PT) took place 2 days a week for 8 weeks. Trunk control measurement scale (TCMS), seated postural control measurement (SPCM), pediatric reach test (PRT), pediatric berg balance measurement (PBBM), 6 minute walking test (6MWT), observational gait scale (OGS), core stability performance measurements, and muscle strength tests were performed.

RESULTS

Mean age of group A (n = 9) was 9 ± 1.58 years, and group B (n = 9) was 10 ± 2.73 years. Significant differences were found in the SPCM posture (p = 0.000), TCMS (p = 0.004), OGS right (p = 0.019) and left (p = 0.001) scores, abdominal fatigue test (AFT) (p = 0.014), modified side bridge (MSBT) test (right p = 0.04, left p = 0.031), pressure biofeedback unit test (PBU) (p = 0.024), and sit-ups test (SUT) (p = 0.011) in favor of group A. According to the initial measurements of the percentage changes of the tests, significantly difference was found in PBBMR (p = 0.001), PBBML (p = 0.000), SPCM posture (0.001), TCMS (0.000), MBSTET (0.000), MSBT left (p = 0.034), AFT (p = 0.002), PBU (p = 0.015), SUT (p = 0.000), MPUT (p = 0.018), and OGS right (p = 0.029) in favor of group A.

CONCLUSION

The results revealed that MPEs in children with CP positively affects trunk, postural control, gait, and balance compared to NDT. It is concluded that MPE can be used as an alternative treatment approach in children with CP.

Effect of a 6-Week Physical Education Intervention on Motor Competence in Pre-School Children with Developmental Coordination Disorder

The objective of this research was to analyze the impact of an intervention program performed by a specialist in physical education (PE) to contribute to the development of motor competence (MC) in pre-school children with motor development problems. The sample consisted of 28 children (12 from the intervention group and 16 from the control group) aged between 4.1 and 5.9 years (mean = 4.71 ± 0.54) who were in the fifth and sixth grades of pre-school education in two schools from Lugo, Spain. The Movement Assessment Battery for Children-2 (MABC-2) was used for data collection. The data revealed that, in the pre- and post-test intervention groups, there are statistically significant differences in manual dexterity (p < 0.001; d = 2.63), aiming and catching (p < 0.002; d = 1.13), balance (p < 0.001; d = 1.68), total test score (p < 0.001; d = 3.30) and total percentile score (p < 0.001; d = 1.88). Between the control and intervention post-test groups, significant differences were found in manual dexterity (p = 0.015; η²&nbsp;= 0.22), aiming and catching (p = 0.003; η²&nbsp;= 0.32), balance (p = 0.050; η² = 0.15), total test score (p < 0.001; η² = 0.47) and total percentile score (p < 0.001; η² = 0.48). Based on the results obtained, a specific MC program implemented by a PE specialist contributed to the improvement of manual dexterity, aiming and catching and balance, as well as a better percentile in the general MC of pre-school children diagnosed with motor skill problems.

Effectiveness of a task-oriented training on occupational performance, functional independence, and fatigue in children with childhood cancer: a randomized-controlled trial

Abstract Objective The objective of the study is to explore the effectiveness of task-oriented training (TOT) on occupational performance, functional independence, and fatigue of children with cancer. Method Two hundred and thirteen children (101 females, 112 males) with cancer were randomized to experimental (n = 112; 9.53±2.23 years) or control (n = 101; 7.93±1.98 years) groups. The experimental group received a TOT together with a conventional occupational therapy (COT), while the control group received only a COT. Both groups received 20 sessions of therapy. The outcomes regarding occupational performance via the Canadian Occupational Performance Measure, functional independence via the Functional Independence Measure for Children and fatigue via the Visual Analog Scale were evaluated by the blind evaluators before and after the interventions in the hospital setting. Results The occupational performance and satisfaction (p<0.001) scores showed statistically significant differences in the experimental group compared to the control group (p<0.01). A statistically significant improvement was determined in functional independence for both groups (p< 0.001). The experimental group indicated a significant reduction in fatigue (p values for fatigue before, during, after activity, morning and evening: p< 0.001) and in the control group (P values for fatigue all situation: p< 0.05). Conclusion The TOT seems to ensure more beneficial effects in increasing occupational performance, improving functional independence in daily activities, and decreasing fatigue at the early phases of inpatient treatment of childhood cancer.

Physical Therapy Management of Children With Developmental Coordination Disorder: An Evidence-Based Clinical Practice Guideline From the Academy of Pediatric Physical Therapy of the American Physical Therapy Association

BACKGROUND

Developmental coordination disorder (DCD), classified as a neurodevelopmental disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), affects approximately 5% to 6% of school-aged children. Characteristics of DCD include poor motor coordination and delayed development of motor skills, not explained by other conditions. Motor deficits negatively affect school productivity, performance in activities of daily living, and recreation participation. Children with coordination problems, at risk for or diagnosed with DCD, should be evaluated by a team of professionals, including a physical therapist (PT).

PURPOSE

This clinical practice guideline (CPG) provides management strategies for PTs and informs clinicians and families about DCD. It links 13 action statements with specific levels of evidence through critical appraisal of the literature and provides recommendations for implementation.

RESULTS/CONCLUSIONS

The DCD CPG addresses examination, referral, first choice and supplemental interventions, discharge, compliance audits, implementation, and research recommendations. Supplemental tools are provided to support PT management.

Evidence and gap map of studies assessing the effectiveness of interventions for people with disabilities in low-and middle-income countries

Background

There are approximately 1 billion people in the world with some form of disability. This corresponds to approximately 15% of the world's population (World Report on Disability, 2011). The majority of people with disabilities (80%) live in low- and middle-income countries (LMICs), where disability has been shown to disproportionately affect the most disadvantaged sector of the population. Decision makers need to know what works, and what does not, to best invest limited resources aimed at improving the well-being of people with disabilities in LMICs. Systematic reviews and impact evaluations help answer this question. Improving the availability of existing evidence will help stakeholders to draw on current knowledge and to understand where new research investments can guide decision-making on appropriate use of resources. Evidence and gap maps (EGMs) contribute by showing what evidence there is, and supporting the prioritization of global evidence synthesis needs and primary data collection.

Objectives

The aim of this EGM is to identify, map and describe existing evidence of effectiveness studies and highlight gaps in evidence base for people with disabilities in LMICs. The map helps identify priority evidence gaps for systematic reviews and impact evaluations.

Methods

The EGM included impact evaluation and systematic reviews assessing the effect of interventions for people with disabilities and their families/carers. These interventions were categorized across the five components of community-based rehabilitation matrix; health, education, livelihood, social and empowerment. Included studies looked at outcomes such as, health, education, livelihoods, social inclusion and empowerment, and were published for LMICs from 2000 onwards until January 2018. The searches were conducted between February and March 2018. The EGM is presented as a matrix in which the rows are intervention categories (e.g., health) and subcategories (e.g., rehabilitation) and the column outcome domains (e.g., health) and subdomains (e.g., immunization). Each cell lists the studies for that intervention for those outcomes, with links to the available studies. Included studies were therefore mapped according to intervention and outcomes assessed and additional filters as region, population and study design were also coded. Critical appraisal of included systematic review was done using A Measurement Tool to Assess Systematic Reviews' rating scale. We also quality-rated the impact evaluation using a quality assessment tool based on various approaches to risk of bias assessment.

Results

The map includes 166 studies, of which 59 are systematic reviews and 107 impact evaluation. The included impact evaluation are predominantly quasiexperimental studies (47%). The numbers of studies published each year have increased steadily from the year 2000, with the largest number published in 2017.The studies are unevenly distributed across intervention areas. Health is the most heavily populated area of the map. A total of 118 studies of the 166 studies concern health interventions. Education is next most heavily populated with 40 studies in the education intervention/outcome sector. There are relatively few studies for livelihoods and social, and virtually none for empowerment. The most frequent outcome measures are health-related, including mental health and cognitive development (n = 93), rehabilitation (n = 32), mortality and morbidity (n = 23) and health check-up (n = 15). Very few studies measured access to assistive devices, nutrition and immunization. Over half (n = 49) the impact evaluation come from upper-middle income countries. There are also geographic gaps, most notably for low income countries (n = 9) and lower-middle income countries (n = 34). There is a fair amount of evidence from South Asia (n = 73) and Sub-Saharan Africa (n = 51). There is a significant gap with respect to study quality, especially with respect to impact evaluation. There appears to be a gap between the framing of the research, which is mostly within the medical model and not using the social model of disability.

Conclusion

Investing in interventions to improve well-being of people with disabilities will be critical to achieving the 2030 agenda for sustainable development goals. The EGM summarized here provides a starting point for researchers, decision makers and programme managers to access the available research evidence on the effectiveness of interventions for people with disabilities in LMICs in order to guide policy and programme activity, and encourage a more strategic, policy-oriented approach to setting the future research agenda.

Efficacy and safety of core stability training on gait of children with cerebral palsy: A protocol for a systematic review and meta-analysis

BACKGROUND

Cerebral palsy (CP) is a common disability in children featured with pathological gait and limb function limitation due to muscle weakness. Improving limb function and quality of life is currently considered to be highlighted. Physiotherapy is a chief component of rehabilitation for children with CP, correcting gait and improve walking capacity through muscle strength training. Standard rehabilitation programs for CP have not been determined. Core stability training (CST), which coordinates limb balance via trunk control, is widely used in sports competition. And it is gradually introduced into the rehabilitation of children with cerebral palsy with a positive impact on the patients' gait performance. By screening published literatures, this study aims to conduct a meta-analysis to systematically evaluate the effectiveness and safety of CST in gait of children with CP.

METHODS

Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) on CST in the treatment of children with CP were searched from 6 databases. Moreover, the reference lists of conference papers and included literatures will be manually searched to avoid omissions. Literature screening and data extraction were performed independently by 2 researchers. RCTs carry out the risk of bias analysis evaluation from seven aspects through the Cochrane Collaboration's risk of bias tool. Fixed or random effect model will be performed to analyze the outcomes. When higher heterogeneity occurs (I > 50%), the sensitivity or subgroup analysis will also be conducted to find potential factors. And the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach is used for assessing the quality of evidence.

RESULTS

The study will evaluate the effect of CST on gait of children with CP from multiple outcomes, including walking speed, endurance, stride length, and safety.

CONCLUSION

Based on evidence-based medicine, the conclusion of this study can demonstrate the effectiveness and safety of CST in gait correction for children with CP.

International clinical practice recommendations on the definition, diagnosis, assessment, intervention, and psychosocial aspects of developmental coordination disorder

AIM

These international clinical practice recommendations (CPR) for developmental coordination disorder (DCD), initiated by the European Academy of Childhood Disability (EACD), aim to address key questions on the definition, diagnosis, assessment, intervention, and psychosocial aspects of DCD relevant for clinical practice.

METHOD

Key questions in five areas were considered through literature reviews and formal expert consensus. For recommendations based on evidence, literature searches on 'mechanisms', 'assessment', and 'intervention' were updated since the last recommendations in 2012. New searches were conducted for 'psychosocial issues' and 'adolescents/adults'. Evidence was rated according to the Oxford Centre for Evidence-Based Medicine (level of evidence [LOE] 1-4) and transferred into recommendations. For recommendations based on formal consensus, two meetings of an international, multidisciplinary expert panel were conducted with a further five Delphi rounds to develop good clinical practice (GCP) recommendations.

RESULTS

Thirty-five recommendations were made. Eight were based on the evidence from literature reviews (three on 'assessment', five on 'intervention'). Twenty-two were updated from the 2012 recommendations. New recommendations relate to diagnosis and assessment (two GCPs) and psychosocial issues (three GCPs). Additionally, one new recommendation (LOE) reflects active video games as adjuncts to more traditional activity-oriented and participation-oriented interventions, and two new recommendations (one GCP, one LOE) were made for adolescents and adults with DCD.

INTERPRETATION

The CPR-DCD is a comprehensive overview of DCD and current understanding based on research evidence and expert consensus. It reflects the state of the art for clinicians and scientists of varied disciplines. The international CPR-DCD may serve as a basis for national guidelines.

WHAT THIS PAPER ADDS

Updated international clinical practice guidelines on developmental coordination disorder (DCD). Refined and extended recommendations on clinical assessment and intervention for DCD. A critical synopsis of current research on mechanisms of DCD. A critical synopsis of psychosocial issues in DCD, with implications for clinical practice. The first international recommendations to consider adolescents and adults with DCD.

Is Group-Based or Individual-Based Intervention more Effective for Quality of Life Outcomes in Children with Developmental Coordination Disorder? A Systematic Review

Aims: To examine whether group-based or individual-based treatment programs are more effective for quality of life (QOL) outcomes in children with developmental coordination disorder (DCD). Methods: A systematic search of the literature was conducted, in accordance with the PRISMA guidelines. Quality of the papers was assessed using the Modified Downs and Black Checklist. Peer-reviewed clinical experimental studies of children diagnosed with DCD with any QOL related outcome measure were included, of all years, languages, and approaches of intervention. Results: Sixteen studies were identified for inclusion, of mixed methodological qualities (predominantly low). Improvement of QOL with both group-based and individual-based interventions were shown, though large degrees of heterogeneity were observed in study designs, participants, modes of interventions, durations, and outcome measures utilized. Conclusions: The effectiveness of group-based versus individual-based interventions on QOL of children with DCD is unclear. There is a pressing need for a high quality, powered trials, utilizing the randomized control trial paradigm, comparing both intervention approaches with standardized treatment approaches and outcome measures to determine and compare the effect on QOL of children with DCD.

Evaluating the evidence for motor-based interventions in developmental coordination disorder: A systematic review and meta-analysis

BACKGROUND

As part of the process of creating an update of the clinical practice guidelines for developmental coordination disorder (DCD) (Blank, Smits-Engelsman, Polatajko, & Wilson, 2012), a systematic review of intervention studies, published since the last guidelines statement was conducted.

AIM

The aim of this study was to 1) systematically review the evidence published from January 2012 to February 2017 regarding the effectiveness of motor based interventions in individuals with DCD, 2) quantify treatment effects using a meta-analysis, 3) examine the available information on different aspects of delivery including use of group intervention, duration and frequency of therapy, and 4) identify gaps in the literature and make recommendations for future intervention research.

METHOD

An electronic search of 5 databases (PubMed, Embase, Pedro, Scopus and Cochrane) was conducted for studies that evaluated motor-based interventions to improve performance for individuals with DCD.

RESULTS

Thirty studies covering 25 datasets were included, 19 of which provided outcomes on standardized measures of motor performance. The overall effect size (Cohen's d) across intervention studies was large (1.06), but the range was wide: for 11 interventions, the observed effect was large (>0.80), in eight studies moderate (>0.50), and in five it was small or negligible (<0.50). Positive benefits were evident for activity-oriented approaches, body function-oriented combined with activities, active video games, and small group programs.

CONCLUSION

Results showed that activity-oriented and body function oriented interventions can have a positive effect on motor function and skills. However, given the varied methodological quality and the large confidence intervals of some studies, the results should be interpreted with caution.

Task-oriented interventions for children with developmental co-ordination disorder

BACKGROUND

Developmental co-ordination disorder (DCD) is a common childhood disorder, which can persist into adolescence and adulthood. Children with DCD have difficulties in performing the essential motor tasks required for self-care, academic, social and recreational activities.

OBJECTIVES

To assess the effectiveness of task-oriented interventions on movement performance, psychosocial functions, activity, and participation for children with DCD and to examine differential intervention effects as a factor of age, sex, severity of DCD, intervention intensity, and type of intervention.

SEARCH METHODS

In March 2017, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, 13 other databases, and five trials registers. We also searched reference lists, and contacted members of the mailing list of the International Conference on DCD to identify additional studies.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) and quasi-RCTs that compared the task-oriented intervention with either an inactive control intervention or an active control intervention in children and adolescents aged four to 18 years with a diagnosis of DCD.Types of outcome measures included changes in motor function, as assessed by standardised performance outcome tests and questionnaires; adverse events; and measures of participation.

DATA COLLECTION AND ANALYSIS

All review authors participated in study selection, data extraction, and assessments of risk of bias and quality, and two review authors independently performed all tasks. Specifically, two review authors independently screened titles and abstracts to eliminate irrelevant studies, extracted data from the included studies, assessed risk of bias, and rated the quality of the evidence using the GRADE approach. In cases of ambiguity or information missing from the paper, one review author contacted trial authors.

MAIN RESULTS

This review included 15 studies (eight RCTs and seven quasi-RCTs). Study characteristicsThe trials included 649 participants of both sexes, ranging in age from five to 12 years.The participants were from Australia, Canada, China, Sweden, Taiwan, and the UK.Trials were conducted in hospital settings; at a university-based clinic, laboratory, or centre; in community centres; at home or school, or both at home and school.The durations of task-oriented interventions were mostly short term (less than six months), with the total number of sessions ranging from five to 50. The length of each session ranged from 30 to 90 minutes, and the frequencies ranged from once to seven times per week.We judged the risk of bias as moderate to high across the studies. Some elements were impossible to achieve (such as blinding of administering personnel or participants).

KEY RESULTS

primary outcomesA meta-analysis of two RCTs and four quasi-RCTs found in favour of task-oriented interventions for improved motor performance compared to no intervention (mean difference (MD) -3.63, 95% confidence interval (CI) -5.88 to -1.39; P = 0.002; I² = 43%; 6 trials, 169 children; very low-quality evidence).A meta-analysis of two RCTs found no effect of task-oriented interventions for improved motor performance compared to no intervention (MD -2.34, 95% CI -7.50 to 2.83; P = 0.38; I² = 42%; 2 trials, 51 children; low-quality evidence).Two studies reported no adverse effects or events. Through personal correspondence, the authors of nine studies indicated that no injuries had occurred.

KEY RESULTS

secondary outcomesDue to the limited number of studies with complete and consistent data, we were unable to perform any meta-analyses on our secondary measures or any subgroup analysis on age, sex, severity of DCD, and intervention intensity.

AUTHORS' CONCLUSIONS

We have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect. The conclusions drawn from previous reviews, which unanimously reported beneficial effects of intervention, are inconsistent with our conclusions. This review highlights the need for carefully designed and executed RCTs to investigate the effect of interventions for children with DCD.

A systematic review of high quality randomized controlled trials investigating motor skill programmes for children with developmental coordination disorder

OBJECTIVE

To identify effective motor training interventions for children with developmental coordination disorder from research graded as high quality (using objective criteria) for the purpose of informing evidence-based clinical practice.

DATA SOURCES

We followed the guidance for conducting systematic reviews issued by the Centre for Reviews and Dissemination. Six OvidSP electronic databases (AMED, All EBM reviews (including Cochrane), Embase, Ovid MEDLINE, PsychARTICLES Full Text, PsycINFO) were searched systematically. We aimed to retain only randomized control trials and systematic reviews of randomized control trials, defined as the highest level of evidence by the Oxford Centre for Evidence-Based Medicine. We searched reference lists of retained articles to identify further appropriate articles.

REVIEW METHODS

Two reviewers critically appraised and categorized articles by effect size (including confidence intervals), inclusion of power calculations and quality using the Physiotherapy Evidence Database (PEDro) scale. Only studies scoring seven or more on the PEDro scale (classed by the PEDro as high reliability) were retained.

RESULTS

No systematic reviews met our criteria for inclusion from 846 articles yielded by the systematic search. Nine randomized control trials investigating 15 interventions to improve motor skills met our inclusion criteria for 'high quality'. Nevertheless, not all included studies were adequately powered for determining an effect.

CONCLUSION

Large effect sizes associated with 95 % confidence intervals suggest that 'Neuromotor Task Training', 'Task-oriented Motor Training' and 'Motor Imagery + Task Practice Training' are the most effective reported interventions for improving motor skills in children with developmental coordination disorder.

The effect of a motor skills training program in the improvement of practiced and non-practiced tasks performance in children with developmental coordination disorder (DCD)

The purpose of the present study was to examine the effect of a group-based task oriented skills training program on motor and physical ability for children with DCD. It was also investigated if there was an effect on fine motor and handwriting tasks that were not specifically practiced during the training program. Forty-one children aged 6-10years took part in this study. Children were assigned to three groups: an experimental training group consisting of 14 children with DCD, a control non-training group consisted of 13 children with DCD and a control non-training group consisting of 14 typically developed children. The measurements included were, the Movement Assessment Battery for Children (MABC), the Modified Agility Test (MAT), the Triple Hop Distance (THD), the 5 Jump-test (5JT) and the Handwriting Performance Test. All measures were administered pre and post an 8-week training program. The results showed that 10 children of the DCD training-group improved their performance in MABC test, attaining a score above the 15th percentile after their participation in the training program. DCD training-group showed a significant improvement on all cluster scores (manual dexterity (t (13)=5.3, p<.001), ball skills (t (13)=2.73, p<.05) and balance (t (13)=5.13, p<.001). Significant performance improvements were also found in MAT, THD, 5JT (t (13)=-4.55; p<.01), handwriting quality (t (12)=-2.73; p<.05) and speed (t (12)=-4.2; p<.01) after the training program. In conclusion, improvement in both practiced and non-practiced skills, in the training program, may reflect improvement in motor skill but also transfer to other skills.
