Portable Touchscreen Assessment of Motor Skill: A Registered Report of the Reliability and Validity of EDNA MoTap.

Portable and flexible administration of manual dexterity assessments is necessary to monitor recovery from brain injury and the effects of interventions across clinic and home settings, especially when in-person testing is not possible or convenient. This paper aims to assess the concurrent validity and test-retest reliability of a new suite of touchscreen-based manual dexterity tests (called EDNA™MoTap) that are designed for portable and efficient administration. A minimum sample of 49 healthy young adults will be conveniently recruited. The EDNA™MoTap tasks will be assessed for concurrent validity against standardized tools (the Box and Block Test [BBT] and the Purdue Pegboard Test) and for test-retest reliability over a 1- to 2-week interval. Correlation coefficients of r > .6 will indicate acceptable validity, and intraclass correlation coefficient (ICC) values > .75 will indicate acceptable reliability for healthy adults. The sample were primarily right-handed (91%) adults aged 19 and 34 years (M = 24.93, SD = 4.21, 50% female). The MoTap tasks did not demonstrate acceptable validity, with tasks showing weak-to-moderate associations with the criterion assessments. Some outcomes demonstrated acceptable test-retest reliability; however, this was not consistent. Touchscreen-based assessments of dexterity remain relevant; however, there is a need for further development of the EDNA™MoTap task administration.

Attention and motor profiles in children with developmental coordination disorder: A neuropsychological and neuroimaging investigation.

AIM: This study aimed to (1) quantify attention and executive functioning in children with developmental coordination disorder (DCD), (2) assess whether some children with DCD are more likely to show attention difficulties, and (3) characterize brain correlates of motor and attention deficits. METHOD: Fifty-three children (36 with DCD and 17 without) aged 8 to 10 years underwent T1-weighted and diffusion-weighted magnetic resonance imaging, and standardized attention and motor assessments. Parents completed questionnaires of executive functioning and symptoms of inattention and hyperactivity. We assessed regional cortical thickness and surface area, and cerebellar, callosal, and primary motor tract structure. RESULTS: Analyses of covariance and one-sample t-tests identified impaired attention, non-motor processing speed, and executive functioning in children with DCD, yet partial Spearman's rank correlation coefficients revealed these were unrelated to one another or the type or severity of the motor deficit. Robust regression analyses revealed that cortical morphology in the posterior cingulate was associated with both gross motor skills and inattentive symptoms in children with DCD, while gross motor skills were also associated with left corticospinal tract (CST) morphology. INTERPRETATION: Children with DCD may benefit from routine attention and hyperactivity assessments. Alterations in the posterior cingulate and CST may be linked to impaired forward modelling during movements in children with DCD. Overall, alterations in these regions may explain the high rate of non-motor impairments in children with DCD. WHAT THIS PAPER ADDS: Children with developmental coordination disorder have difficulties in attention, processing speed, and executive functioning. Non-motor impairments were not interrelated or correlated with the type or severity of motor deficit. Posterior cingulate morphology was associated with gross motor skills and inattention. Gross motor skills were also associated with left corticospinal tract morphology.

Evaluation of daily and social participation of children with Cerebral Palsy across different age groups with a focus on the 'F'-words: Function, family, fitness, fun, friends and future.

BACKGROUND: The impact of disability differs across cultures. This study aimed to determine the predictors of participation in children with cerebral palsy (CP) in Turkey, based on the six F-words. METHODS: Cross-sectional study exploring participation profiles of 450 children with CP, aged between 2 and 18 years. Pediatric Evaluation of Disability Inventory (PEDI) evaluated functional skills, and Assessment of Life Habits (LIFE-H) version 3.0 assessed daily and social participation. Hierarchical linear regression models were done to determine the predictors of participation in daily activities (PDA) and social roles (PSR) in three age groups (2-4, 5-13 and 14-18 years) based on the 6 F-words (mobility of PEDI for 'fitness'; four classification systems and self-care of PEDI for 'functioning'; social functions of PEDI for 'friends'; demographic information by parents for 'family'; the recreation of LIFE-H for 'fun'; and different stages of development for 'future'). RESULTS: The most important predictors for total PDA by age group were: self-care (p = 0.012) of PEDI in 2-4 y; self-care (p = 0.001) and mobility (p = 0.005) of PEDI in 5-13 y; GMFCS (p = 0.006) and mobility (p = 0.002) of PEDI in 14-18 y. Significant predictors for PSR differed by age group: self-care (p = 0.001) of PEDI in 2-4 y; self-care (p = 0.023) and mobility (p = 0.006) of PEDI in 5-13 y; and GMFCS (p = 0.004) and MACS (p = 0.003) in 14-18 y. CONCLUSIONS: Six F-words of function and fitness focussed on self-care in younger children with an increasing emphasis on mobility and ability levels according to age. Therefore, rehabilitation for different aspects of the functional levels is needed to improve participation in life across the six F-words framework; plus take into consideration context, age-differences, family's expectations, life requirements, environmental needs, and cultural differences.

Development of complex executive function over childhood: Longitudinal growth curve modeling of performance on the Groton Maze Learning Task.

This longitudinal study modeled children's complex executive function (EF) development using the Groton Maze Learning Task (GMLT). Using a cohort-sequential design, 147 children (61 males, 5.5-11 years) were recruited from six multicultural primary schools in Melbourne and Perth, Australia. Race/ethnicity data were not available. Children were assessed on the GMLT at 6-month intervals over 2-years between 2010 and 2012. Growth curve models describe age-related change from 5.5 to 12.5 years old. Results showed a quadratic growth trajectory on each measure of error-that is, those that reflect visuospatial memory, executive control (or the ability to apply rules for action), and complex EF. The ability to apply rules for action, while a rate-limiting factor in complex EF, develops rapidly over early-to-mid childhood.

Upper Limb Kinematics of Handwriting among Children with and without Developmental Coordination Disorder.

Background: Children with developmental coordination disorder (DCD) often experience difficulties with handwriting legibility and speed. This study investigates the relationship between handwriting and upper limb kinematics to characterize movement patterns of children with DCD and typically developing (TD) children. Methods: 30 children with and without DCD matched for age, gender, and parent education were compared across handwriting abilities using a standardized handwriting assessment of both copied and dictated tasks (A-A Handwriting). The 3D motion capture system (Qualysis) was used to analyze upper limb kinematics and characterize movement patterns during handwriting and contrasted with written output. Results: Children with DCD wrote fewer legible letters in both copying and dictation. Children with DCD also showed poor automatization of key writing concepts. Atypical wrist postures were associated with reduced legibility for children with DCD (F (1,27) 4.71, p = 0.04, p-η2 = 0.15); whereas for TD children, better legibility was associated with greater variations in movement speed, particularly of the wrist (rho = −0.578, p < 0.05). Conclusion: Results reflect different movement parameters influencing handwriting in children with DCD. An improved understanding of the movement characteristics during handwriting of these children may assist intervention design.

Behavioral and Neuroimaging Research on Developmental Coordination Disorder (DCD): A Combined Systematic Review and Meta-Analysis of Recent Findings.

AIM: The neurocognitive basis of Developmental Coordination Disorder (DCD; or motor clumsiness) remains an issue of continued debate. This combined systematic review and meta-analysis provides a synthesis of recent experimental studies on the motor control, cognitive, and neural underpinnings of DCD. METHODS: The review included all published work conducted since September 2016 and up to April 2021. One-hundred papers with a DCD-Control comparison were included, with 1,374 effect sizes entered into a multi-level meta-analysis. RESULTS: The most profound deficits were shown in: voluntary gaze control during movement; cognitive-motor integration; practice-/context-dependent motor learning; internal modeling; more variable movement kinematics/kinetics; larger safety margins when locomoting, and atypical neural structure and function across sensori-motor and prefrontal regions. INTERPRETATION: Taken together, these results on DCD suggest fundamental deficits in visual-motor mapping and cognitive-motor integration, and abnormal maturation of motor networks, but also areas of pragmatic compensation for motor control deficits. Implications for current theory, future research, and evidence-based practice are discussed. SYSTEMATIC REVIEW REGISTRATION: PROSPERO, identifier: CRD42020185444.

Impacts of goal setting on engagement and rehabilitation outcomes following acquired brain injury: a systematic review of reviews.

PURPOSE: To appraise and synthesize evidence from previous systematic reviews (SRs) concerning the impacts of goal setting on engagement in the rehabilitation process and on outcomes of participation and occupational performance for individuals with acquired brain injury (ABI). MATERIALS AND METHODS: Systematic review of SRs following the preferred reporting items for SRs and meta-analysis guidelines. Sixteen full text articles were assessed for eligibility, from which four were included in the review. The Critical Appraisal Skills Programme checklists for SRs was used to rate quality and risk of bias. RESULTS: Four SRs of moderate to high quality included a variety of methodologies. Evidence of moderate quality showed clients' active participation in goal setting had positive impacts on the client and their engagement in the process. Findings suggested that goal-directed interventions, particularly in outpatient rehabilitation, may improve occupational performance. There was some indication that goal setting may support adherence to therapeutic exercises, but relevance to rehabilitation outcomes was less clear. Findings related to participation outcomes were minimal. CONCLUSIONS: Goal setting is a complex and multidimensional process. Goal setting may contribute to improved engagement in rehabilitation although few studies explored occupational performance and participation outcomes for individuals with ABI.Implications for rehabilitationActive goal setting may contribute to improved engagement in rehabilitation, however, including individual clients in the goal setting process requires creativity and flexibility on behalf of professionals.A model is presented to promote understanding of the personal and environmental barriers and facilitators that may interact with goal setting approaches to promote engagement in rehabilitation.There is a need for more research exploring impact of active client-centered goal setting on occupational performance and participation outcomes for people with acquired brain injury.

Cognitive function and performance of everyday activities in adults with spina bifida.

BACKGROUND AND OBJECTIVE: Individuals with spina bifida often have cognitive impairments leading to dif-ficulties in education and daily activities. The aims of this study were to explore cognitive impairments in adults with spina bifida and to consider associations between impairments, educational outcome and per-formance of daily activities, comparing individuals with and without intellectual disability. METHODS: Data were collected on 35 adults with spina bifida via cognitive tests and Assessment of Motor and Process Skills (AMPS). Participants were divided into 3 groups: individuals without intellectual disability who completed compulsory education (NID-C); those without intellectual disability, who failed to successfully pass compulsory education (NID-F); and those with intellectual disability failed to successfully pass compulsory education (ID-F). RESULTS: All individuals with intellectual disability failed to successfully pass compulsory education (group ID-F) and had poorer scores across almost all measures than group NID-F and significantly poorer scores than group NID-C. All except 6 individuals scored below cut-off levels for effort and safety on both AMPS motor and process scales; more significant associations were seen between the cognitive tests and the motor rather than process scale. CONCLUSION: Cognitive impairments, irrespective of intellectual disability, impact on the performance of eve-ryday activities and on educational achievement, and thus need to be considered in assessments and inter-ventions to improve outcomes and promote independence in people with spina bifida.

Feasibility of a randomised controlled trial to evaluate home-based virtual reality therapy in children with cerebral palsy.

PURPOSE: Evidence is increasing for effective virtual reality therapy for motor rehabilitation for children with Cerebral Palsy. We assessed the feasibility of a virtual reality therapy mode of intervention, appropriateness of measures, and potential cost-effectiveness. METHODS: A 12-week, 2-group, parallel-feasibility trial (ISRCT 17624388) using Nintendo Wii FitTM at home. Children aged 5-16, with ambulatory Cerebral Palsy, who were able to follow simple instructions were randomised to two groups; one supported by physiotherapists (individualised activity programme), the other unsupported with children having free choice (control). Children were assessed in clinic at baseline, week 6, and week 12 by blinded assessors. Feasibility of the intervention was assessed via recruitment, adherence, and usefulness of measurement tools. RESULTS: Forty-four children were eligible (out of 48 approached): 31 consented, 30 were randomised, 21 completed the study; 10 in the supported group and 11 in the unsupported group. Nine children discontinued from tiredness, after-school activities, homework, surgery, technical difficulties or negative system feedback. The supported group completed 19 of 36 (IQR 5-35) possible sessions; the unsupported group 24 of 36 sessions (IQR 8-36). Gross Motor Function Measure scores varied by Cerebral Palsy severity after the intervention. There were no adverse events. CONCLUSION: Virtual reality therapy offers potential as a therapeutic adjunct for children with Cerebral Palsy, warranting substantive confirmatory study. Gross Motor Function Measure, with modifications to improve sensitivity, appeared appropriate as a primary measure, with Timed up and Go test secondary. The intervention was inexpensive costing £20 per child. An explanatory trial to evaluate the clinical/cost-effectiveness of commercial system virtual reality therapy is feasible with minor methodological adaptation. Implications for rehabilitation Home-based interactive computer gaming was feasible, safe and cost effective as a therapy adjunct. Discontinue if additional pressures are present: imminent surgery, family resilience to technical difficulties, negative system feedback, after-school activities. Change in Gross Motor Function Measurement scores varied by severity of Cerebral Palsy.

Cognitive and motor function in developmental coordination disorder.

AIM: To analyse the development of motor skill and executive function in school-aged children with and without developmental coordination disorder (DCD). METHOD: Using a longitudinal design, 186 children (86 males, 100 females) aged 6 to 11 years at Time 1 were tested over a 2-year period, 52 of whom were diagnosed with DCD at Time 1 (27 males, 25 females; mean age 8y 5mo, SD 1y 6mo) using DSM-5 criteria. The McCarron Assessment of Neuromuscular Development assessed motor status at Time 1 and at 2-year follow-up (Time 2). Executive function was assessed using a well-validated measure, the Groton Maze Learning Test. RESULTS: The DCD cohort at Time 1 had moderate incidence of executive function deficit (41%). Most importantly, at a group level, children with persisting DCD (across Times 1 and 2) also showed significantly lower levels of executive function than children with typical motor development at both time points. At an individual level, around 26% of children in this group had persisting executive function deficits relative to normal ranges of performance. INTERPRETATION: Children with persisting DCD are at significant risk of executive function issues. The combination of motor and cognitive issues as a potential risk factor in the longer-term development of children is discussed. WHAT THIS PAPER ADDS: Around half of children initially diagnosed with developmental coordination disorder (DCD) had the same diagnosis at 2-year follow-up. 41% of children with DCD have impaired executive function. Children with persisting DCD show poorer executive function than those with typical motor development or remitting DCD.

Student Perceptions of Growth-Facilitating and Growth-Constraining Factors of Practice Placements: A Comparison between Japanese and United Kingdom Occupational Therapy Students.

This study compared growth-facilitating and growth-constraining experiences of practice placements as perceived by occupational therapy students from Japan and the United Kingdom (UK). Fifteen students from Japan and 14 from the UK used a nominal group technique (NGT) to rank, individually and in groups, their subjective learning experiences during practice placements. Qualitative analysis and simple tabulation based on ranking of items obtained in the NGT were performed. Five item categories were identified from both Japanese and UK students: self-reflection, the role of supervisor, sense of responsibility, clinical knowledge and skills, and time management. Results showed that all students perceived opportunities for self-reflection and feedback from supervisors as growth facilitating and students' passive attitudes towards requirements of practice placements as growth constraining. Country-specific differences between students were observed in clinical knowledge and skills, sense of responsibility, and time management. Japanese students perceived that preparatory study led to successfully treating clients during placement, and they tended to commit to placement assignments at the expense of time outside. UK students valued working independently with a sense of responsibility but considered time-management problems within their placement hours as growth constraining. These differences can be explained by different social norms and expectations of students from Japan and the UK.

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.

To Explore the Validity of Change Scores of the Children's Hand-use Experience Questionnaire (CHEQ) in Children with Unilateral Cerebral Palsy.

AIMS: To explore the validity of change scores of the Children's Hand-use Experience Questionnaire (CHEQ). METHODS: Analysis of the CHEQ included 44 children (15 girls) between 6-16 years (median 9.0; IQR 8-11) with unilateral cerebral palsy, with baseline and post- (two-week intensive) intervention assessments using the Goal Attainment Scale (GAS) as external anchor for change. Hypotheses on the magnitude of expected change were formulated and correlation coefficients and effect sizes calculated. Receiver operating curve analysis was performed and the area under the curve (AUC) calculated to investigate the ability of CHEQ to discriminate between improvement and non-improvement according to GAS. RESULTS: All hypotheses about the magnitude of change were confirmed supporting longitudinal validity of CHEQ scales to measure change in the perception of bimanual performance. AUCs for the Grasp efficacy and the Time utilization were slightly below, and for the Feeling bothered slightly above the threshold. The latter one accurately discriminating between children that improved and did not improve according to the GAS. CONCLUSIONS: Evidence was found that CHEQ scales capture change in bimanual performance but with limited accuracy for two out of three scales. The validity of CHEQ change scores needs to be further explored in a wider population.

Dance and rehabilitation in cerebral palsy: a systematic search and review.

AIM: To conduct a review of research literature on the use of dance and movement with music (rhythmic auditory stimulation [RAS]) in the neurorehabilitation of children and adults with cerebral palsy (CP). METHOD: We conducted a systematic search and quality appraisal of the research literature on dance and RAS in CP. Additionally, we linked the research outcomes to the International Classification of Functioning, Disability and Health (ICF) framework. RESULTS: Studies showed preliminary evidence of the benefits of dance and RAS on body functions, particularly balance, gait, walking, and cardiorespiratory fitness for individuals with CP. Research gaps are evident across all domains of the ICF, particularly in the participation and environment domains. INTERPRETATION: To facilitate translation of quantitative research outcomes to the clinical classification of the ICF, a table was constructed that links traditional areas of quantitative rehabilitation research with the ICF categories highlighting areas of research strengths and areas where increased rigor is desirable. The potential for dance and RAS to have positive impacts on body functions, emotional expression, social participation, and attitudinal change are indicated areas for consideration in future research. WHAT THIS PAPER ADDS: The potential for dance and movement to music help balance, gait, and walking in children and adults with cerebral palsy. Research gaps are evident across International Classification of Functioning, Disability and Health domains, particularly participation and environment domains.

Understanding Organisational Ability and Self-Regulation in Children with Developmental Coordination Disorder.

PURPOSE OF THE REVIEW: This paper examines physical and emotional coherence in young people with developmental coordination disorder (DCD). Specifically, the transactional relationship between motor and non-motor/executive dysfunction in children with DCD and its impact on psychosocial functioning is explored. RECENT FINDINGS: This paper integrates the subjective reported experiences of young people with DCD with objective measurements and findings from neuroimaging studies. SUMMARY: Consideration of the transactional relationship between the person, the activity and the environment, whether these factors be physical, social, attitudinal or virtual, will be fundamental to our understanding of the mechanisms underpinning organisational and emotional issues presenting in DCD. Integrating the experiences of young people with research evidence will be essential to improve outcomes for young people with DCD in clinical practice.
