Reliability of Selected Health-Related Fitness Tests for Children With Developmental Coordination Disorder.

Aim: To quantify test-retest reliability and minimal detectable change for 90 and 95% confidence levels (90MDC, 95MDC) for health-related fitness tests in children with developmental coordination disorder (DCD). Methods: Lower limb muscle strength [hand-held dynamometry (HHD), unilateral heel rise test (UHRT), standing broad jump (SBJ)], muscle endurance [Muscle Power Sprint Test (MPST)] and cardiorespiratory endurance [20-metre Shuttle Run Test (20mSRT)] were evaluated twice (2-7 day interval) in 31 children with DCD (20 males, 9.4 years old ± 2.0). Results: Test-retest reliability was reported as intraclass correlation coefficient (ICC) (2, 1) 95% confidence interval lower bounds. Values were excellent for MPST (peak and mean power: 0.93, 0.95), good for HHD (0.81-0.88), SBJ (0.82), and the 20mSRT (0.87) and moderate for UHRT (0.74). For HHD, the 90MDC and 95MDC were the largest for hip extensors (14.47, 12.14 Nm) and the smallest for ankle dorsiflexors (1.55, 1.30 Nm). For UHRT, SBJ, MPST and the 20mSRT, these MDC values were 11.90, 9.98 repetitions; 25.49, 21.38 cm; 4.70, 3.94 W (mean power), and 6.45, 5.42 W (peak power) and 0.87, 0.73 (number of stages), respectively. Conclusion: These tests yield reliable test-retest results that can be used to evaluate fitness changes in this group.

Systematic review of the psychometric properties of cultural adaptations and translations of the Children's Assessment of Participation and Enjoyment (CAPE).

BACKGROUND: The Children's Assessment of Participation and Enjoyment (CAPE) is the most widely used questionnaire for the assessment of children participation. While several cultural adaptations and translations exist, the quality of the methods used to produce them, as well as their psychometric properties, remains unclear. The aim of this systematic review was to evaluate the different translated and/or culturally adapted versions of the CAPE for children and youth with and without disabilities. METHOD: A search was performed in five electronic databases CINAHL (EBSCO), MEDLINE (OVID), EMBASE (ELSEVIER), PSYCINFO (OVID), and WEB OF SCIENCE Core Collection (CLARIVATE), for articles available in French or English with the last update in July 2022. All studies related to a cultural adaptation and/or translation of the CAPE were retained and evaluated based on established guidelines for cross-cultural adaptations and measurement properties. The extraction was done independently by two authors. A critical appraisal of translation and psychometric properties methods was performed. Critical appraisal of the articles was done using the Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures tool and the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology. RESULTS: The search identified 642 studies (321 duplicates removed), 16 of which underwent full-text review. Nine studies met all inclusion criteria and underwent analysis. According to the recommended steps for cross-cultural adaptations, one study performed 100% of the steps and two others performed 80%. None of the studies met all the recommendations for the evaluation of psychometric properties. A full evaluation of reliability and internal consistency were reported by 74% of studies. None of the studies reported a full evaluation of responsiveness, agreement and/or construct validity. CONCLUSIONS: This review demonstrated limitations in the robustness of the methods used to develop and evaluate translated and culturally adapted versions of CAPE. To ensure valid and reliable results when conducting future research using the CAPE, it is recommended to fully evaluate the psychometric properties of the existing versions and to produce other translated and culturally adapted versions of the questionnaire.

Growth and muscle strength development in children with developmental coordination disorder.

AIM: To assess effects of growth on lower limb maximal isometric muscle strength (MIMS) development in children with developmental coordination disorder (DCD). METHOD: This observational study used hand-held dynamometry to evaluate MIMS (hip abductors, flexors, extensors; knee flexors and extensors; ankle dorsiflexors) in children with DCD (n=33, 12 females, 21 males, 6-12y, mean [SD] age 9y [2y]). Regression analysis compared changes in MIMS for similar changes in growth (height or body mass) for children with DCD and typically developing children (pre-existing database, n=183), controlling for age and sex. RESULTS: For the same height gain, the gain in muscle strength was 37.3% to 69.2% less in children with DCD compared with typically developing children, with significantly lower slopes (p-value between <0.001-0.042) in all muscle groups tested except knee extensors and ankle dorsiflexors in females. Strength gains related to body mass gains were not different for children with DCD compared to typically developing children. INTERPRETATION: Even when growing at a similar rate, children with DCD do not develop muscle strength gains at the same rate as their typically developing peers. WHAT THIS PAPER ADDS: Strength gains with growth (height) may be reduced in children with developmental coordination disorder.

Participation in leisure activities in adolescents with congenital heart defects.

AIM: To describe leisure participation in adolescents with congenital heart defects (CHD) and identify factors associated with intensity of participation. METHOD: Eighty adolescents with CHD were recruited (39 males, 41 females; mean age [SD] 15y 8mo [1y 8mo] range 11y 5mo-19y 11mo) of whom 78 completed the Children's Assessment of Participation and Enjoyment (CAPE) outcome measure of leisure participation. The measure has five subscales: recreational, active-physical, social, skill-based, and self-improvement. Associations between the CAPE and age, sex, and development were examined. Motor ability (Movement Assessment Battery for Children, Second Edition), cognition (Leiter International Performance Scale-Revised), behavior (Strengths and Difficulties Questionnaire), and motivation (Dimensions of Mastery Questionnaire) were assessed. RESULTS: Participants exhibited impaired motor (43.5%), behavioral (23.7%), and cognitive (29.9%) development. The most intense participation was in social (mean [SD] 3.3 [0.99]) and recreational (2.9 [0.80]) activity types on the CAPE. Male sex (p<0.05) and younger age were associated with greater physical activity (<15y: 1.87; ≥15y: 1.31, p<0.05). Greater engagement in social activities was related to better cognition (r=0.28, p<0.05), higher motor function (r=0.30-0.36, p<0.01), and fewer behavioral difficulties (r=-0.32 to -0.47, p<0.01). Cognitive ability (r=0.27, p<0.05), dexterity and aiming/catching (r=0.27-0.33, p<0.05), and behavior problems (r=0.38-0.49, p=0.001) were correlated with physical activity participation. Persistence in tasks, an aspect of motivation, correlated with physical (r=0.45, p<0.001) and social activity involvement (r=0.28, p<0.05). INTERPRETATION: Ongoing developmental impairments in adolescents with CHD are associated with decreased active-physical and social engagement, putting them at risk of poor physical and mental health. Health promotion strategies should be considered. WHAT THIS PAPER ADDS: Adolescents with congenital heart defects (CHD) have limited engagement in active-physical leisure activities. Cognitive, motor, and behavioral impairments are associated with decreased participation in leisure in children with CHD. Female sex and older age are associated with less engagement in leisure. Mastery motivation correlates with participation, suggesting an avenue for intervention.

Participación en actividades recreativas en adolescentes con cardiopatías congénitas OBJETIVO: Describir la participación en el tiempo libre en adolescentes con defectos cardíacos congénitos (CHD) e identificar los factores asociados con la intensidad de la participación. MÉTODO: Ochenta adolescentes con CHD fueron reclutados (39 varones, 41 mujeres; edad media [DE] 15 años 8 meses [1 año 8 meses] rango 11 año 5 meses- 19 año 11 meses) de los cuales 78 completaron la medida de resultado de la Evaluación de la Participación y el Disfrute de los Niños (Children's Assessment of Participation and Enjoyment [CAPE]) del ocio participación. La medida tiene cinco subescalas: recreación, actividad física, social, basada en habilidades y mejoría personal. Se examinaron las asociaciones entre el CAPE y la edad, el sexo y el desarrollo. Se evaluó la capacidad motora con la Batería de Evaluación de Movimiento para Niños (Movement Assessment Battery for Children, Segunda edición), la cognición (Leiter International Performance Scale-Revised), el comportamiento con el Cuestionario de Fortalezas y Dificultades (Strengths and Difficulties Questionnaire) y la motivación usando el cuestionario Dimensiones del Dominio (Dimensions of Mastery Questionnaire). RESULTADOS: Los participantes exhibieron problemas en el desarrollo motor (43.5%), conducta (23.7%) y en el desarrollo cognitivo (29.9%). La participación más intensa fue en los tipos de actividad social (media [DE] 3.3 [0.99]) y recreativa (2.9 [0.80]) en el CAPE. El sexo masculino (p <0.05) y la edad más joven se asociaron con una mayor actividad física (<15 años: 1.87; ≥15 años: 1.31, p <0.05). Una mayor participación en actividades sociales se relacionó con una mejor cognición (r = 0.28, p <0.05), una función motora más alta (r = 0.30-0.36, p <0.01) y menos dificultades en el comportamiento (r = -0.32 a -0.47, p < 0,01). La capacidad cognitiva (r = 0.27, p <0.05), la destreza manual y la habilidad para apuntar y atajar (r = 0.27-0.33, p <0.05) y los problemas de comportamiento (r = 0.38-0.49, p = 0.001) se correlacionaron con la participación en la actividad física. La capacidad de persistir en las tareas, un aspecto de la motivación se correlacionó con la participación física (r = 0.45, p <0.001) y la actividad social (r = 0.28, p <0.05). INTERPRETACIÓN: Los problemas de desarrollo en los adolescentes con CHD están asociados con una disminución de la participación física y social, lo que los pone a riesgo de una pobre salud física y mental. Deben buscarse estrategias para la promoción de la salud de esta población.

Participação em atividades de lazer em adolescentes com defeitos cardíacos congênitos OBJETIVO: Descrever a participação em lazer de adolescentes com defeitos cardíacos congênitos (DCC) e identificar fatores associados com a intensidade de participação. MÉTODO: Oitenta adolescentes com DCC foram recrutados (39 do sexo masculino, 41 do sexo feminino; média de idade [DP] 15a 8m [1a 8m] variação 11a 5m-19a 11m), dos quais 78 completaram a medida de participação em lazer Avaliação da participação e diversão das crianças (APDC). A medida tem cinco subescalas: recreacional, ativa-física, social, baseada em habilidades, e auto-aprimoramento. Associações entre a APDC e idade, sexo e desenvolvimento foram examinadas. A capacidade motora (Bateria de avaliação do movimento para crianças, segunda edição), cognição (Escala internacional de desempenho de Leiter- Revisada), comportamento (Questionário de capacidades e dificuldades), e motivação (Questionário de Dimensões do Domínio) foram avaliados. RESULTADOS: Os participantes exibiram comprometimento do desenvolvimento motor (43,5%), comportamental (23,7%), e cognitivo (29,9%). A participação mais intensa segundo a APDC foi nos tipos social (média [DP] 3,3 [0,99]) e recreacional (2.9 [0,80]). O sexo masculino (p<0,05) e menor idade foram associados com maior nível de atividade física (<15a: 1,87; ≥15a: 1,31, p<0,05). Um maior engajamento em atividades sociais foi relacionado com uma melhor cognição (r=0,28, p<0,05), maior função motora (r=0,30-0,36, p<0,01), e menos dificuldades comportamentais (r=-0,32 a -0,47, p<0,01). A capacidade cognitiva (r=0,27, p<0,05), destreza e mirar/apreender (r=0,27-0,33, p<0,05), e problemas comportamentais (r=0,38-0,49, p=0,001) foram correlacionadas com a participação em atividades físicas. A persistência nas tarefas, um aspecto da motivação, se correlacionou com o envolvimento em atividades físicas (r=0,45, p<0,001) e sociais (r=0,28, p<0,05). INTERPRETAÇÃO: Alterações persistentes do desenvolvimento de adolescentes com DCC são associadas com engajamento ativo-físico e social reduzidos, o que os coloca em risco para sua saúde física e mental. Estratégias de promoção de saúde deveriam ser consideradas.

A Comparison of Developmental Outcomes of Adolescent Neonatal Intensive Care Unit Survivors Born with a Congenital Heart Defect or Born Preterm.

OBJECTIVE: To compare cognitive, motor, behavioral, and functional outcomes of adolescents born with a congenital heart defect (CHD) and adolescents born preterm. STUDY DESIGN: Adolescents (11-19 years old) born with a CHD requiring open-heart surgery during infancy (n = 80) or born preterm ≤29 weeks of gestational age (n = 128) between 1991 and 1999 underwent a cross-sectional evaluation of cognitive (Leiter International Performance Scale-Revised), motor (Movement Assessment Battery for Children-II), behavioral (Strengths and Difficulties Questionnaire), and functional (Vineland Adaptive Behavior Scale-II) outcomes. Independent samples t tests and Pearson χ2 or Fisher exact tests were used to compare mean scores and proportions of impairment, respectively, between groups. RESULTS: Adolescents born with a CHD and adolescents born preterm had similar cognitive, motor, behavioral, and functional outcomes. Cognitive deficits were detected in 14.3% of adolescents born with a CHD and 11.8% of adolescents born preterm. Motor difficulties were detected in 43.5% of adolescents born with a CHD and 50% of adolescents born preterm. Behavioral problems were found in 23.7% of adolescents in the CHD group and 22.9% in the preterm group. Functional limitations were detected in 12% of adolescents born with a CHD and 7.3% of adolescents born preterm. CONCLUSIONS: Adolescents born with a CHD or born preterm have similar profiles of developmental deficits. These findings highlight the importance of providing long-term surveillance to both populations and guide the provision of appropriate educational and rehabilitation services to better ameliorate long-term developmental difficulties.

Research and knowledge transfer priorities in developmental coordination disorder: Results from consultations with multiple stakeholders.

BACKGROUND: Priority-setting is a way to focus research and knowledge translation (KT) efforts for community-based research partnerships (CBRP). OBJECTIVE: To identify the developmental coordination disorder (DCD) research and KT priorities of stakeholders in Quebec, Canada, and their perceptions regarding the implementation of a CBRP. DESIGN: An advisory committee oversaw the research process including an online survey and four community forums. SETTING AND PARTICIPANTS: The survey was posted online and four community forums were organized. Participants included parents of children with DCD, adults with DCD, health professionals and school staff. MAIN VARIABLES: Stakeholder generated research and KT priorities, and optimal CBPR conditions. OUTCOME MEASURES: Participants selected their top five priorities based on a predefined list of 16 research and 12 KT priorities determined in collaboration with the advisory committee. They also rated the importance of various CBRP conditions. Preliminary survey results were discussed during the forums. RESULTS: Survey participants (n = 395) identified interwoven research and KT priorities where access to services was considered to be essential: supporting children at school; improving DCD identification and diagnosis; preventing secondary consequences; improving the organization of services and implementing effective services. Forum participants (n = 52) confirmed the relevance of these priorities and supported the establishment of a CBRP inclusive of all stakeholders to improve DCD services, research and KT. DISCUSSION AND CONCLUSIONS: A general consensus emerged among all groups, but adults with DCD were more concerned with employment than were the other stakeholder groups. These findings are presently being used to shape an ongoing, online CBRP.

Validity of Instrumented Insoles for Step Counting, Posture and Activity Recognition: A Systematic Review.

With the growing interest in daily activity monitoring, several insole designs have been developed to identify postures, detect activities, and count steps. However, the validity of these devices is not clearly established. The aim of this systematic review was to synthesize the available information on the criterion validity of instrumented insoles in detecting postures activities and steps. The literature search through six databases led to 33 articles that met inclusion criteria. These studies evaluated 17 different insole models and involved 290 participants from 16 to 75 years old. Criterion validity was assessed using six statistical indicators. For posture and activity recognition, accuracy varied from 75.0% to 100%, precision from 65.8% to 100%, specificity from 98.1% to 100%, sensitivity from 73.0% to 100%, and identification rate from 66.2% to 100%. For step counting, accuracies were very high (94.8% to 100%). Across studies, different postures and activities were assessed using different criterion validity indicators, leading to heterogeneous results. Instrumented insoles appeared to be highly accurate for steps counting. However, measurement properties were variable for posture and activity recognition. These findings call for a standardized methodology to investigate the measurement properties of such devices.

Design and Accuracy of an Instrumented Insole Using Pressure Sensors for Step Count.

Despite the accessibility of several step count measurement systems, count accuracy in real environments remains a major challenge. Microelectromechanical systems and pressure sensors seem to present a potential solution for step count accuracy. The purpose of this study was to equip an insole with pressure sensors and to test a novel and potentially more accurate method of detecting steps. Methods: Five force-sensitive resistors (FSR) were integrated under the heel, the first, third, and fifth metatarsal heads and the great toe. This system was tested with twelve healthy participants at self-selected and maximal walking speeds in indoor and outdoor settings. Step counts were computed based on previously reported calculation methods, individual and averaged FSR-signals, and a new method: cumulative sum of all FSR-signals. These data were compared to a direct visual step count for accuracy analysis. Results: This system accurately detected steps with success rates ranging from 95.5 ± 3.5% to 98.5 ± 2.1% (indoor) and from 96.5 ± 3.9% to 98.0 ± 2.3% (outdoor) for self-selected walking speeds and from 98.1 ± 2.7% to 99.0 ± 0.7% (indoor) and 97.0 ± 6.2% to 99.4 ± 0.7% (outdoor) for maximal walking speeds. Cumulative sum of pressure signals during the stance phase showed high step detection accuracy (99.5 ± 0.7%⁻99.6 ± 0.4%) and appeared to be a valid method of step counting. Conclusions: The accuracy of step counts varied according to the calculation methods, with cumulative sum-based method being highly accurate.

Reliability of Inclinometer-Derived Passive Range of Motion Measures in Youth with Cerebral Palsy.

Aims: This study evaluated, for youth with cerebral palsy (CP), the reliability of passive range of motion (PROM) measures taken with an inclinometer, a device that may be simpler to use than a goniometer. Methods: The PROM for elbow and wrist extension, ankle dorsal flexion (knee flexed 90° and fully extended), and the knee popliteal angle of 30 youth with CP (18 boys, 12 girls, 7.0 ± 3.8 years old, classified in Gross Motor Function Classification levels I-V) was measured using an inclinometer. Two physical therapists took the measures during two different sessions, a maximum of 1 week apart. Results: Good mean intra-rater inter-session, inter-rater intra-session, and inter-rater inter-session reliability (ICC = 0.75-0.89), was found for the elbow, ankle, and knee sites. Absolute reliability for these sites and conditions was 7-14° (90% confident) and 10-16° (95% confident). Reliability values for wrist extension were comparable, albeit slight lower. Conclusions: Similar to published values for goniometry, inclinometery yields reliable upper and lower limb PROM measures from ambulatory and non-ambulatory youth with CP whether measures are carried out by different evaluators within or across sessions or whether measures are performed by the same evaluator across sessions.

Educational and rehabilitation service utilization in adolescents born preterm or with a congenital heart defect and at high risk for disability.

AIM: This historical cohort study describes the use of educational and rehabilitation services in adolescents born preterm or with a congenital heart defect (CHD). METHOD: Parents of 76 young people (mean age 15y 8mo [SD 1y 8mo]) with CHD and 125 born ≤29 weeks gestational age (mean age 16y [SD 2y 5mo]) completed a demographics questionnaire including educational and rehabilitation resource utilization within the previous 6 months. Rehabilitation services included occupational therapy, physical therapy, speech language pathology, psychology. Developmental (Leiter Brief IQ, Movement-ABC, Strengths and Difficulties Questionnaire) and functional (Vineland) status of the young people was assessed. Pearson χ2 tests were used to perform simple pairwise comparisons of categorical outcomes across the two groups (CHD, preterm). Univariate logistic regression was used to examine predictors of service utilization. RESULTS: Developmental profiles of the two groups (CHD/preterm) were similar (29.9%/30% IQ<80; 43.5%/50.0% motor difficulties; 23.7%/22.9% behavior problems). One-third received educational supports or attended segregated schools. Only 16% (preterm) and 26.7% (CHD) were receiving rehabilitation services. Services were provided predominantly in the school setting, typically weekly. Few received occupational therapy or physical therapy (1.3-7.6%) despite functional limitations. Leiter Brief IQ<70 was associated with receiving educational supports (CHD: OR 5.53, 95% CI 1.29-23.68; preterm: OR 14.63, 3.10-69.08) and rehabilitation services (CHD: OR 4.46, 1.06-18.88; preterm: OR 5.11, 1.41-18.49). Young people with motor deficits were more likely to require educational (CHD: OR 5.72, 1.99-16.42; preterm: OR 3.11, 1.43-6.77) and rehabilitation services (preterm: OR 3.97, 1.21-13.03). INTERPRETATION: Although young people with impairments were more likely to receive educational and rehabilitation services, many may not be adequately supported, particularly by rehabilitation specialists. Rehabilitation services at this important transition phase could be beneficial in optimizing adaptive functioning in the home, school, and community.

Ottawa Panel Evidence-Based Clinical Practice Guidelines for Structured Physical Activity in the Management of Juvenile Idiopathic Arthritis.

OBJECTIVE: To create guidelines focused on the use of structured physical activity (PA) in the management of juvenile idiopathic arthritis (JIA). DATA SOURCES: A systematic literature search was conducted using the electronic databases Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), EMBASE (Ovid), and Physiotherapy Evidence Database for all studies related to PA programs for JIA from January 1966 until December 2014, and was updated in May 2015. STUDY SELECTION: Study selection was completed independently by 2 reviewers. Studies were included if they involved individuals aged ≤21 years diagnosed with JIA who were taking part in therapeutic exercise or other PA interventions for which effects of various disease-related outcomes were compared with a control group (eg, no PA program or activity of lower intensity). DATA EXTRACTION: Two reviewers independently extracted information on interventions, comparators, outcomes, time period, and study design. The statistical analysis was reported using the Cochrane Collaboration methods. The quality of the included studies was assessed according to the Physiotherapy Evidence Database Scale. DATA SYNTHESIS: Five randomized controlled trials (RCTs) fit the selection criteria; of these, 4 were high-quality RCTs. The following recommendations were developed: (1) Pilates for improving quality of life, pain, functional ability, and range of motion (ROM) (grade A); (2) home exercise program for improving quality of life and functional ability (grade A); (3) aquatic aerobic fitness for decreasing the number of active joints (grade A); and (4) and cardio-karate aerobic exercise for improving ROM and number of active joints (grade C+). CONCLUSIONS: The Ottawa Panel recommends the following structured exercises and physical activities for the management of JIA: Pilates, cardio-karate, home and aquatic exercises. Pilates showed improvement in a higher number of outcomes.

Factors Associated With Moderate to Vigorous Physical Activity in Adolescents Born Preterm.

PURPOSE: Little is known about the physical activity of adolescents born prematurely. This study aimed to: 1) describe relationships between moderate to vigorous physical activity (MVPA) in adolescents born prematurely and various factors and, 2) compare their MVPA level to guidelines. METHOD: A secondary analysis was performed using data from 64 adolescents (16.1 ± 2.5 years old, born £29 weeks gestation; 57.8% girls). Time spent in MVPA was based on accelerometry data. Sociodemographic, prematurity and comorbidity variables were based on questionnaire data or, for movement difficulty, from the results of the Movement Assessment Battery for Children-Second Edition. RESULTS: Multiple regression analysis showed that participants who were older (b = -4.52, p < .001), female (b = 14.18, p = .014), with movement difficulty (b = 18.64, p = .014), with health problems (b = 11.78, p = .036) and without hyperactive behavior (trend, b = 2.04, p = .099) spent less time in MVPA. Together these variables explained 44.4% of the variance in MVPA. Most participants (79.7%) did not meet Canadian MVPA guidelines. CONCLUSION: Study results suggest that physical activity interventions should especially target adolescents born prematurely who are older, female, with health problems, and with marked movement difficulties.

Ottawa Panel Evidence-Based Clinical Practice Guidelines for Foot Care in the Management of Juvenile Idiopathic Arthritis.

OBJECTIVE: To create evidence-based guidelines evaluating foot care interventions for the management of juvenile idiopathic arthritis (JIA). DATA SOURCES: An electronic literature search of the following databases from database inception to May 2015 was conducted: MEDLINE (Ovid), EMBASE (Ovid), Cochrane CENTRAL, and clinicaltrials.gov. STUDY SELECTION: The Ottawa Panel selection criteria targeted studies that assessed foot care or foot orthotic interventions for the management of JIA in those aged 0 to ≤18 years. The Physiotherapy Evidence Database scale was used to evaluate study quality, of which only high-quality studies were included (score, ≥5). A total of 362 records were screened, resulting in 3 full-text articles and 1 additional citation containing supplementary information included for the analysis. DATA EXTRACTION: Two reviewers independently extracted study data (intervention, comparator, outcome, time period, study design) from the included studies by using standardized data extraction forms. Directed by Cochrane Collaboration methodology, the statistical analysis produced figures and graphs representing the strength of intervention outcomes and their corresponding grades (A, B, C+, C, C-, D+, D, D-). Clinical significance was achieved when an improvement of ≥30% between the intervention and control groups was present, whereas P>.05 indicated statistical significance. An expert panel Delphi consensus (≥80%) was required for the endorsement of recommendations. DATA SYNTHESIS: All included studies were of high quality and analyzed the effects of multidisciplinary foot care, customized foot orthotics, and shoe inserts for the management of JIA. Custom-made foot orthotics and prefabricated shoe inserts displayed the greatest improvement in pain intensity, activity limitation, foot pain, and disability reduction (grades A, C+). CONCLUSIONS: The use of customized foot orthotics and prefabricated shoe inserts seems to be a good choice for managing foot pain and function in JIA.

Acute Physical Exercise Affects Cognitive Functioning in Children With Cerebral Palsy.

Little is known about the effects of acute exercise on the cognitive functioning of children with cerebral palsy (CP). Selected cognitive functions were thus measured using a pediatric version of the Stroop test before and after maximal, locomotor based aerobic exercise in 16 independently ambulatory children (8 children with CP), 6-15 years old. Intense exercise had: 1) a significant, large, positive effect on reaction time (RT) for the CP group (preexercise: 892 ± 56.5 ms vs. postexercise: 798 ± 45.6 ms, p < .002, d = 1.87) with a trend for a similar but smaller response for the typically developing (TD) group (preexercise: 855 ± 56.5 ms vs. postexercise: 822 ± 45.6 ms, p < .08, d = 0.59), and 2) a significant, medium, negative effect on the interference effect for the CP group (preexercise: 4.5 ± 2.5%RT vs. postexercise: 13 ± 2.9%RT, p < .04, d = 0.77) with no significant effect for the TD group (preexercise: 7.2 ± 2.5%RT vs. postexercise: 6.9 ± 2.9%RT, p > .4, d = 0.03). Response accuracy was high in both groups pre- and postexercise (>96%). In conclusion, intense exercise impacts cognitive functioning in children with CP, both by increasing processing speed and decreasing executive function.

The Effects of Acute Intense Physical Exercise on Postural Stability in Children With Cerebral Palsy.

This study evaluated the effects of intense physical exercise on postural stability of children with cerebral palsy (CP). Center of pressure (CoP) was measured in 9 typically developing (TD) children and 8 with CP before and after a maximal aerobic shuttle-run test (SRT) using a single force plate. Anteroposterior and mediolateral sway velocities, sway area, and sway regularity were calculated from the CoP data and compared between pre- and postexercise levels and between groups. Children with CP demonstrated significantly higher pre-SRT CoP velocities than TD children in the sagittal (18.6 ± 7.6 vs. 6.75 1.78 m/s) and frontal planes (15.4 ± 5.3 vs. 8.04 ± 1.51 m/s). Post-SRT, CoP velocities significantly increased for children with CP in the sagittal plane (27.0 ± 1.2 m/s), with near-significant increases in the frontal plane (25.0 ± 1.5m/s). Similarly, children with CP evidenced larger sway areas than the TD children both pre- and postexercise. The diminished postural stability in children with CP after short but intense physical exercise may have important implications including increased risk of falls and injury.

Hand-Held Dynamometry Isometric Torque Reference Values for Children and Adolescents.

PURPOSE: To establish hand-held dynamometry (HHD) maximal isometric muscle torque (MIT) reference values for children and adolescents who are developing typically. METHODS: The MIT of 10 upper and lower limb muscle groups was assessed in 351 Caucasian youth (4 years 2 months to 17 years) using a standardized HHD protocol, previously shown to be feasible, valid, and reliable. RESULTS: The mean MIT and 95% confidence interval of the mean for all muscle groups, for each of the 14 age groups (1 year age span for each group), and for each sex, were reported in both absolute (Nm) and normalized (Nm/kg) values. CONCLUSION: These HHD reference values may be helpful in the identification of muscle strength impairments in several pediatric populations, especially when bilateral impairments are present.

Translation, cross-cultural adaptation and validation of the French version of the Knee Outcome Survey-Activities of Daily Living Scale.

PURPOSE: The Activities of Daily Living Scale of the Knee Outcome Survey (KOS-ADLS) is a joint-specific questionnaire measuring functional limitation experienced by individuals with knee disorders. The original English version of the KOS-ADLS has been shown to be highly reliable and responsive to change. The purpose of this study was to perform a translation and cross-cultural adaptation of the original version of the KOS-ADLS questionnaire into French and to validate this French version of the questionnaire. METHOD: In accordance with standard procedure, the original version of the KOS-ADLS was translated and cross-culturally adapted into French. Once the final French version of the KOS-ADLS was developed, it was subjected to further psychometric evaluation with 76 individuals with knee disorders. Each participant completed the KOS-ADLS on three occasions: at baseline, two days later to evaluate test-retest reliability, and four weeks later to evaluate responsiveness. Symptoms and function-oriented construct questions were also completed to evaluate construct-convergent and known-group validity. RESULTS: The cross-cultural adaptation procedure revealed no major problems with content or language. The French version of the KOS-ADLS showed excellent test-retest reliability with low measurement error (intraclass correlation coefficient = 0.92, minimal detectable change = 8.3), as well as high responsiveness (standardized response mean = 1.41; clinically important difference = 13.6). Further, it discriminates between different levels of self-rated or clinician-rated knee function. CONCLUSIONS: The French version of the KOS-ADLS is a reliable, valid and responsive questionnaire for the assessment of functional limitation in individuals with musculoskeletal knee disorders.

The Development and Pilot Testing of a Fidelity Checklist for a Family-Centered Telehealth Intervention for Parents of Children with Motor Delay.

This multi-methods study describes the development of a pediatric rehabilitation telehealth intervention fidelity checklist, estimates its inter-rater reliability, and documents raters' implementation experience. A literature scan and expert consultation identified eighteen key behaviors and categorized them into three subdomains, measured using a 5-point measurement system. To estimate the checklist's inter-rater reliability, three raters scored 33 video recordings. A Shrout and Fleiss Class 1,1 intraclass correlation (ICC)) and 95% confidence intervals (CI) calculated ICCs = 0.5 (CI: 0, 0.9) for both the Therapist and the Parent-Therapists subdomains, and the Parent subdomain an ICC = 0.3 (CI: 0, 0.8). In the implementation surveys, raters reported high levels of satisfaction (100%), ease of use (84% to 88%), and confidence in their video ratings (87% to 100%). Changes in procedures and scoring were recommended. Capturing raters' implementation experiences is crucial in the early evaluation of the fidelity checklists for telehealth.

Maximal cardiorespiratory fitness testing in individuals with chronic stroke with cognitive impairment: practice test effects and test-retest reliability.

OBJECTIVES: To evaluate, for individuals with chronic stroke with cognitive impairment, (1) the effects of a practice test on peak cardiorespiratory fitness test results; (2) cardiorespiratory fitness test-retest reliability; and (3) the relationship between individual practice test effects and cognitive impairment. DESIGN: Cross-sectional. SETTING: Rehabilitation center. PARTICIPANTS: A convenience sample of 21 persons (men [n=12] and women [n=9]; age range, 48-81y; 44.9±36.2mo poststroke) with cognitive impairments who had sufficient lower limb function to perform the test. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Peak oxygen consumption (Vo(2)peak, ml·kg(-1)·min(-1)). RESULTS: Test-retest reliability of Vo(2)peak was excellent (intraclass correlation coefficient model 2,1 [ICC2,1]=.94; 95% confidence interval [CI], .86-.98). A paired t test showed that there was no significant difference for the group for Vo(2)peak obtained from 2 symptom-limited cardiorespiratory fitness tests performed 1 week apart on a semirecumbent cycle ergometer (test 2-test 1 difference, -.32ml·kg(-1)·min(-1); 95% CI, -.69 to 1.33ml·kg(-1)·min(-1); P=.512). Individual test-retest differences in Vo(2)peak were, however, positively related to general cognitive function as measured by the Mini-Mental State Examination (ρ=.485; P<.026). CONCLUSIONS: Vo(2)peak can be reliably measured in this group without a practice test. General cognitive function, however, may influence the effect of a practice test in that those with lower general cognitive function appear to respond differently to a practice test than those with higher cognitive function.

Anaerobic performance in children with cerebral palsy compared to children with typical development.

PURPOSE: Using a locomotor-based field test of anaerobic performance, this study compared the anaerobic performance of children with spastic cerebral palsy (CP) who walk without support with that of peers who are typically developing. METHODS: The Muscle Power Sprint Test was performed by 159 children with CP (102 boys, mean age 9.7 ± 1.5 years; and 57 girls, mean age 9.5 ± 1.6 years) classified at Gross Motor Function Classification System level I (n = 115) or level II (n = 44) and 376 children with typical development (175 boys, mean age 8.9 ± 1.8 years; and 201 girls, mean age 9.0 ± 1.7 years). RESULTS: The anaerobic performance of the children with CP was lower than that of peers with typical development. CONCLUSIONS: The difference between the 2 groups increased with height, especially for the children with CP classified at Gross Motor Function Classification System level II. Children with CP appear to have impaired anaerobic performance.
