Modified sports interventions for children and adolescents with disabilities: A scoping review

AIM

To establish the scope of the literature on modified sports interventions for children and adolescents with disabilities.

METHOD

For this scoping review, articles were screened and the characteristics of studies were extracted. The modified sports interventions were described in terms of their structure, using the items of the Template for Intervention Description and Replication. Components of intervention treatment were described by using the language of the Rehabilitation Treatment Specification System. Results were analysed and validated by a group of professionals, using the Public and Patient Involvement strategy.

RESULTS

Twelve studies were eligible for inclusion, investigating interventions for children with autism spectrum disorder, cerebral palsy, and other conditions. Most studies presented a moderate level of evidence. Active ingredients were repeated sports-related motor training and introduction to the sport through a 'learning by action' mechanism. The intervention target was gross motor skills performance, and intervention aims (indirect outcomes) were physical activity participation and different body functions.

INTERPRETATION

The inclusion of stakeholders in this review helped to validate our findings about the characteristics and structure of modified sports interventions, to identify research gaps, and to provide a step process for clinical implementation. Future investigations are warranted of the effectiveness of modified sports investigations with better quality studies, including participation outcomes and studies with non-ambulant children.

WHAT THIS PAPER ADDS

Modified sports interventions target sport-related skills performance and aim to achieve physical activity participation and body functions. These interventions included group-based, sports-related motor skills training and introduction to sports in real-world environments. They are offered mostly for ambulant children with autism spectrum disorder and cerebral palsy. Most studies of modified sports interventions presented moderate level of evidence.

Checks and balances: a meta-analysis on the known-groups validity of functional postural control tests in children

INTRODUCTION

Pediatric physical therapists commonly treat children with postural control deficits. Ideally, pediatric functional postural control tests should therefore be able to identify postural control deficits in children with various disorders. Despite a plethora of available tests, evidence for their validity - especially known-groups - remains scarce. This review aims to determine the known-group validity of available functional postural control tests to differentiate various pediatric pathological groups of different ages from their typically developing (TD) peers.

EVIDENCE ACQUISITION

PubMed, Web of Science and Scopus were systematically searched (last update: February 2023; PROSPERO: CRD42023408982). Forty case-control studies with a pathological pediatric sample (N.=1331) and TD peers (N.=1889) were included and selected for data-extraction and -analysis. Risk of bias was assessed using the SIGN checklist and level of evidence was scored using GRADE. Random-effect meta-analyses were performed to estimate pooled standardized mean differences (SMD) for the various test types and subclassified based on pathology and/or age.

EVIDENCE SYNTHESIS

When compared with TD peers, children with underlying pathologies performed significantly worse on pediatric functional postural control test batteries (SMD=-2.21), the Timed Up and Go Test and variants (SMD=2.30), the One Leg Stance test and variants (SMD=-2.14), while the Reach tests showed a smaller difference (SMD=-1.19). Subclassification within the meta-analyses showed that pathology was an influencing factor for the test batteries and the one leg stance test and variants. Age was an influencing factor for the reach tests. None of the included functional postural control tests exceeded a low level of evidence.

CONCLUSIONS

Pediatric functional postural control tests that assess multiple aspects of postural control (such as test batteries) seem to offer higher known-groups validity than single-task tests (e.g. reach tests). The underlying pathology has a larger impact on the validity of these tests than age. There remains an overall low level of evidence for the known-groups validity of pediatric functional postural control tests indicating the need for research with more homogenous groups and norm reference data.

Acquisition and Retention Effects of Fundamental Movement Skills on Physical Activity and Health-Related Fitness of Children with Autism Spectrum Disorder

This study adopted a quasi-experimental design to explore the effects of fundamental movement skill intervention on the acquisition and retention of physical activity levels and health-related fitness in children with autism spectrum disorder (ASD). In the experiments, 11 children received fundamental motor skill training (12 weeks, 60 min/session, 4 times/week), and 10 children maintained traditional physical activity. Assessments were performed using an ActiGraph GT3X+ accelerometer, health-related fitness pre-post intervention, and 1-month follow-up tests. The sedentary time during physical activity was significantly decreased (p = 0.01), and there were large changes in health-related physical fitness indicators, including significantly improved body composition (body mass index, F(1,19) = 8.631, p = 0.03, partial η2 = 0.312), muscle strength and endurance (sit-ups, F(1,19) = 3.376, p = 0.02, partial η2 = 0.151 and vertical jumps, F(1,19) = 5.309, p = 0.04, partial η2 = 0.218), and flexibility (sit and reach, F(1,19) = 36.228, p = 0.02, partial η2 = 0.656). Moreover, the follow-up tests showed that the children's sedentary time continued to reduce, and the muscle strength and endurance (sit-ups, F(1,19) = 4.215, p = 0.01, partial η2 = 0.426) improved continuously after the intervention. Based on this study, actionable and regular fundamental movement skill programs can be provided in the future as an effective way to achieve the healthy development goals of children with ASD.

Getting into the game: evaluation of the reliability, validity and utility of the Ignite Challenge scale for school-aged children with autism spectrum disorder

PURPOSE

Evaluate reliability, concurrent validity and utility of the Ignite Challenge motor skills measure for children with autism spectrum disorder (ASD).

MATERIALS/METHODS

In this measurement study, children completed the Ignite Challenge twice, 1-3 weeks apart. A physiotherapist assessor (one of seven) conducted a child's test-retest assessments and scored administration ease and child engagement (/10 visual analogue scale). A second assessor rated baseline assessment videos. Validity data (parent-report PEDI-CAT) were collected at baseline. Reliability analysis employed ICCs (95% CI) and evaluated minimum detectable change (MDC80). Pearson's correlations (r) estimated validity.

RESULTS

Forty-seven children with ASD (mean 9.34 years [SD = 2.35]; 10 girls; independent social communication) were tested at baseline; 45 were retested. Ignite Challenge baseline and retest mean scores were 69.0% (SD = 17.1) and 69.5% (SD = 16.6) respectively, with excellent inter-rater/test-retest reliability (ICC = 0.96 [95% CI 0.92, 0.97] and ICC = 0.91 [95% CI 0.84, 0.95]) respectively, and MDC80 = 9.28. Administration ease and child engagement were 6.5/10 (SD = 2.4) and 6.7/10 (SD = 2.2). Ignite Challenge and PEDI-CAT Social/Mobility (n = 45) associations were r = 0.54 and 0.57. Minimal suggestions for measure revisions arose from child/assessor feedback.

CONCLUSIONS

Ignite Challenge can reliably identify movement strengths and challenges of children with ASD. Use may permit more appropriate evaluation and goal setting within physical activity-based programs.

Diagnosing autism severity associated with physical fitness and gray matter volume in children with autism spectrum disorder: Explainable machine learning method

PURPOSE

This study aimed to investigate the relationship between physical fitness, gray matter volume (GMV), and autism severity in children with autism spectrum disorder (ASD). Besides, we sought to diagnose autism severity associated with physical fitness and GMV using machine learning methods.

METHODS

Ninety children diagnosed with ASD underwent physical fitness tests, magnetic resonance imaging scans, and autism severity assessments. Diagnosis models were established using extreme gradient boosting (XGB), random forest (RF), support vector machine (SVM), and decision tree (DT) algorithms. Hyperparameters were optimized through the grid search cross-validation method. The shapley additive explanation (SHAP) method was employed to explain the diagnosis results.

RESULTS

Our study revealed associations between muscular strength in physical fitness and GMV in specific brain regions (left paracentral lobule, bilateral thalamus, left inferior temporal gyrus, and cerebellar vermis I-II) with autism severity in children with ASD. The accuracy (95 % confidence interval) of the XGB, RF, SVM, and DT models were 77.9 % (77.3, 78.6 %), 72.4 % (71.7, 73.2 %), 71.9 % (71.1, 72.6 %), and 66.9 % (66.2, 67.7 %), respectively. SHAP analysis revealed that muscular strength and thalamic GMV significantly influenced the decision-making process of the XGB model.

CONCLUSION

Machine learning methods can effectively diagnose autism severity associated with physical fitness and GMV in children with ASD. In this respect, the XGB model demonstrated excellent performance across various indicators, suggesting its potential for diagnosing autism severity.

Effects of a Long-Term Adapted Judo Program on the Health-Related Physical Fitness of Children with ASD

Physical fitness is one of the most important physical and mental health aspects for children with Autism Spectrum Disorder (ASD). This study aimed to test the effects of a long-term adapted judo program on the health-related physical fitness of children with ASD. The participants were recruited from various associations of families and schools for children with special needs. Twenty-one children were assigned to an experimental group and nineteen to a control group. The experimental group participated in a six-month adapted judo program consisting of 90 min of practice each week. Health-related physical fitness was measured using the indicators obtained from the ALPHA-fitness battery, the estimated VO₂max and the waist/height ratio^0.5. Changes within and between groups were analyzed using linear mixed models for repeated measures designs and test-retest reliability of tests requiring a maximum score using the Intraclass Correlation Coefficient (ICC). A judo program tailored for children with ASD can improve the cardio-metabolic health and cardiorespiratory fitness of its participants. The problems involved with administering physical aptitude tests that involve maximum effort or performance in children with ASD cast serious doubts on the reproducibility of their results.

Effects of Square-Stepping Exercise on Motor and Cognitive Skills in Autism Spectrum Disorder Children and Adolescents: A Study Protocol

Individuals with autism spectrum disorder (ASD) diagnoses present not only cognitive, emotional, communicative, and social challenges but also movement issues that affect their everyday activities, learning, and leisure. The use of the square-stepping exercise (SSE), a motor program initially created to strengthen the lower limbs of older adults, is spreading because of its advantages (e.g., balance and lower limb strength improvements). A study protocol to assess the SSE effects on motor, sensory, and cognitive skills in Spanish children and adolescents between 6 and 12 years old with ASD diagnoses is presented. A randomised clinical will be performed, recruiting 52 children and adolescents with ASD who will be distributed into two groups: an experimental (n = 26) and a control (n = 26) group. The SSE sessions will be held for 9 weeks (two times per week). The main variable will be balance, which will be measured with the Movement Assessment Battery for Children 2 (MABC2), and secondary outcomes will include sensory processing, attention, and executive functions. Assessments will be carried out before and at the end of the program implementation, including an additional follow up one month later. If this program obtains positive results, it should be implemented in different settings (schools, clinics, associations, etc.) to improve the quality of movement and development in children and adolescents with ASD, as it is an easy-to-use and structured tool.

Irish Para Report Card on Physical Activity of Children and Adolescents With Disabilities

For the first time, data on children and adolescents with disabilities in Ireland are reported based on the Active Healthy Kids Global Alliance Para Report Card methodology. The most recent data from the last 10 years were used in the grading process (A+ to F), and indicators with insufficient data were graded as incomplete. Of the 10 indicators from the Global Matrix Para Report Cards, grades were assigned to Overall Physical Activity (F), Organized Sport (D), Active Transport (D-), Sedentary Behaviors (D-), Family & Peers (C), School (C-), Community & Environment (B-), and Government (B). Irish disability sport organizations were invited to assess the research-led audit and provided commentary around the final grading. The contextual discussion of the grades is presented through the lens of strengths, weaknesses, opportunities, and threats with the purpose being to provide direction for the reduction of physical activity disparities among children with disabilities.

Fundamental Motor Skill Delays in Preschool Children With Disabilities: 2012 National Youth Fitness Survey

Delays in fundamental motor skill (FMS) competency have been observed in a variety of children with disabilities. However, evidence of FMS delays is largely limited to small, geographically specific, limitedly diverse, and non-representative samples. The purpose of this study was to examine the association between FMS competency and reported disability status among pre-school children, ages 3–5 years, using the 2012 National Youth Fitness Survey (NYFS). In total, 329 preschool children (49% female; 4.00 ± 0.04 years of age) from the 2012 NYFS completed the Test of Gross Motor Development−2, including 43 preschoolers identified with a disability based on parental report (44% female; 4.20 ± 0.16 years). Associations were examined with logistic regression using sampling weights. Poor FMS competency, defined as gross motor quotient scores ≤ 79, was observed in significantly more children with disabilities (29%) than children without disabilities (10%, OR = 3.5, p = 0.04). While not statistically significant, there was a growing disparity in FMS competency at age 5 (41 vs. 11%) compared to age 3 (15 vs. 9%, OR = 1.80, p = 0.30). The results provide additional evidence for poor FMS competency among pre-school children with disabilities. FMS should be an early part of comprehensive assessments for all children suspected of disability or development delay as it is critical to identify and intervene upon FMS delays before discrepancies can widen.
