Effectiveness and Evidence Level of Dance on Functioning of Children and Adolescents with Neuromotor Impairments: A Systematic Review.

OBJECTIVES: The aim of this paper is to investigate the effects of dance therapy in children with neuromotor impairments (CNI), organizing the outcomes according to International Classification of Functioning Disability and Health (ICF) domains, and to investigate if there is adequate evidence of effectiveness to recommend dance as a therapy. METHODS: Electronic searches were conducted in December 2021. We include studies assessing the effects of dance in CNI up to 18 years. Data extraction included studies' populations, intervention features, and main outcomes. We classified outcomes according to the ICF framework. We used the Cochrane collaboration's tool, modified by effective practice and organization of care (EPOC), to assess the methodological quality. The GRADE synthesized the body of evidence. RESULTS: Twelve studies were included, with most of them addressing the body structure and function and activity components of ICF. Only three studies addressed components of participation, and four of personal factors. All these studies reported the positive effects of dance. Nevertheless, all of them presented high risk of bias. We found very low evidence level for improvement of body structure and function and activity components. CONCLUSION: Dance therapy presents low evidence level for improvements of body structure and function and activity in CNI. Further studies with low risk of bias and larger samples are needed.

Dual-task effects in children with neuromotor dysfunction: a systematic review.

INTRODUCTION: Based on the assumption that motor actions result from the interaction between cognitive, perceptual, mechanical and neurological mechanisms, neuromotor dysfunctions are expected to impair central coordination processes required to perform dual-tasks. The aim of the present work was to systematically review the literature concerning the effects of dual-task in the activities performed by children with neuromotor dysfunctions. EVIDENCE ACQUISITION: A tailored search strategy in relevant databases was conducted by two independent reviewers in August 2018 seeking for online articles published in English evaluating dual-task (motor-motor, cognitive-cognitive or cognitive-motor) effects on activities in subjects with neuromotor dysfunctions younger than 18 years. The following data were extracted: category of dual-task paradigm (motor-motor; cognitive-cognitive; cognitive-motor), primary and secondary tasks, study methods, methodological quality of the studies, and research gaps in the literature. EVIDENCE SYNTHESIS: We identified 13 full-text reports that fulfilled the predefined inclusion and exclusion criteria. CONCLUSIONS: There are a few high-quality studies addressing dual-task effects on activities performed by children with neuromotor dysfunctions. These children show greater susceptibility to dual-task costs than typical ones. There is a lack of studies addressing children with CP and Down Syndrome, which are highly prevalent and commonly seen in clinical settings. Thus, dual-task effects in children with neuromotor dysfunctions remain a wide research field, with need for further studies to fill in the existing gaps.

Clinical tools designed to assess motor abilities in children with cerebral palsy.

OBJECTIVE: This systematic review aimed to list the tools used by rehabilitation professionals to test motor abilities in children with cerebral palsy (CP), to determine if these tools have psychometric properties specifically measured for CP, and to identify the main characteristics of these tools. METHOD: Web of Science, PEDro, PubMed/MEDLINE, Science Direct, and SciELO databases were searched to identify the tools. PubMed/MEDLINE was then searched to identify the studies assessing those tools' psychometric properties. The agreement-based standards for the selection of health measurement tools and the Terwee criteria were used to assess the quality and the results of each included study, respectively. RESULTS: Eighteen tools were identified. The psychometric properties of many of the tools used with children with CP have not been evaluated for this population. CONCLUSION: The psychometric properties evaluated often have a poor methodological quality of measurement. Overall, we suggest the tools with most empirical support to evaluate children with CP.

Postural control during sit-to-stand movement and its relationship with upright position in children with hemiplegic spastic cerebral palsy and in typically developing children.

OBJECTIVE: The purpose of this study was to compare postural control in typically developing (TD) children and children with cerebral palsy (CP) during the sit-to-stand (STS) movement and to assess the relationship between static (during static standing position) and dynamic postural control (during STS movement) in both groups. METHOD: The center of pressure (CoP) behavior of 23 TD children and 6 children with spastic hemiplegic CP (Gross Motor Function Classification System [GMFCS] I and II) was assessed during STS movement performance and during static standing conditions with the use of a force plate. The data obtained from the force plate were used to calculate CoP variables: anteroposterior (AP) and mediolateral (ML) amplitudes of CoP displacement and the area and velocity of CoP oscillation. RESULTS: According to the Mann-Whitney test, children with CP exhibited higher CoP values in all of the analyzed variables during the beginning of STS movement. Pearson's correlation verified a positive correlation between the CoP variables during both static conditions and the performance of STS movement. CONCLUSIONS: Children with spastic hemiplegic CP present major postural oscillations during the beginning of STS movement compared with typical children. Moreover, the observed relationship between postural control in static and dynamic conditions reveals the importance of body control in the static position for the performance of functional activities that put the body in motion, such as STS movement.

Relationship between static postural control and the level of functional abilities in children with cerebral palsy / Relação entre o controle postural estático e o nível de habilidades funcionais na paralisia cerebral

Background: Postural control deficits can impair functional performance in children with cerebral palsy (CP) in daily living activities. Objective: To verify the relationship between standing static postural control and the functional ability level in children with CP. Method: The postural control of 10 children with CP (gross motor function levels I and II) was evaluated during static standing on a force platform for 30 seconds. The analyzed variables were the anteroposterior (AP) and mediolateral (ML) displacement of the center of pressure (CoP) and the area and velocity of the CoP oscillation. The functional abilities were evaluated using the mean Pediatric Evaluation of Disability Inventory (PEDI) scores, which evaluated self-care, mobility and social function in the domains of functional abilities and caregiver assistance. Results: Spearman's correlation test found a relationship between postural control and functional abilities. The results showed a strong negative correlation between the variables of ML displacement of CoP, the area and velocity of the CoP oscillation and the PEDI scores in the self-care and caregiver assistance domains. Additionally, a moderate negative correlation was found between the area of the CoP oscillation and the mobility scores in the caregiver assistance domain. We used a significance level of 5% (p <0.05). Conclusions: We observed that children with cerebral palsy with high CoP oscillation values had lower caregiver assistance scores for activities of daily living (ADL) and consequently higher levels of caregiver dependence. These results demonstrate the repercussions of impairments to the body structure and function in terms of the activity levels of children with CP such that postural control impairments in these children lead to higher requirements for caregiver assistance. .

Contextualização: Os déficits de controle postural em crianças com PC podem comprometer suas atividades na rotina diária. Objetivo: Verificar a relação entre o controle postural em ortostatismo de crianças com PC e suas habilidades funcionais. Método: O controle postural de dez crianças PC (GMFCS I e II) foi avaliado em ortostatismo na plataforma de força por 30 segundos. Variáveis analisadas: deslocamento ântero-posterior e médio-lateral do centro de pressão (CoP), área e velocidade de oscilação do CoP. As habilidades funcionais foram avaliadas por meio do Pediatric Evaluation of Disability Inventory (PEDI), considerando-se escores de autocuidado, mobilidade e função social nos domínios habilidades funcionais e assistência do cuidador. Resultados: O teste de correlação de Spearman verificou a relação entre controle postural e funcionalidade. Constatou-se correlação negativa forte entre as variáveis amplitude ML de deslocamento do CoP, área de oscilação do CoP e entre a variável de velocidade média de oscilação do CoP e os escores do domínio de autocuidado. Observou-se também correlação negativa moderada entre área de oscilação do CoP e mobilidade. O nível de significância adotado foi de 5% (p<0,05). Conclusões: Crianças com maiores oscilações do CoP em ortostatismo apresentam maiores escores de assistência do cuidador para a realização de AVDs, indicando maiores níveis de dependência. Isso demonstra as repercussões dos componentes de estrutura e função do corpo sobre o nível de atividade em crianças com PC, uma vez que o comprometimento do controle postural pode levar a uma maior dependência das crianças em relação ...

Reliability of isokinetic evaluation in passive mode for knee flexors and extensors in healthy children.

BACKGROUND: The isokinetic dynamometer has been considered the gold-standard measurement of muscle performance. However, the reliability for the passive mode in children has not been reported to date. OBJECTIVES: The purpose was to evaluate the reliability of the isokinetic dynamometer in passive mode in children. METHOD: Twenty-one healthy children (ten girls, eleven boys), aged 5 to 12 years (age: 8.5±2.2 years), were evaluated using an isokinetic dynamometer. Each participant was tested twice with a one-week interval and performed five consecutive cycles of knee extension and flexion. The test was performed at 60º/s in the concentric passive mode and the children performed maximal contractions. The measured variables were peak torque, average peak torque, total work, and average power, time to peak torque and angle of peak torque for dominant and non-dominant lower limbs. Reliabilities were determined using intraclass correlation coefficient (ICC3,1), standard error of measurement (SEM and SEM%), and coefficient of variation (CV). RESULTS: We found good reliability in both lower limbs for peak torque, average peak torque, total work and average power of knee flexors and extensors, with ICC3,1 values greater than 0.80; SEM ranging from 6.7 to 79.2; SEM% ranging from 10.4% to 16.8%; CV lower than 15%. Bland-Altman analysis showed that the bias was low than 10% and limits of agreement (LOAs) ranging from 33.9% to 59.2%, and -28.8% and -52.8%, showing that measures tended to disagree. However, time to peak torque (ICC3,1<0.68; SEM > 0.34; SEM%>37.4%; CV>41.7%; bias >24.0%; LOA>101.0%) and angle of peak torque (ICC3,1<0.76; SEM>9.3; SEM%>27.6%; CV>15.3%; bias>11.0%; LOA>61.0%) were not reliable. CONCLUSIONS: The findings indicate that isokinetic evaluation in passive mode for knee extensors and flexors of dominant and non-dominant lower limbs of children without disabilities was reliable for peak torque, average peak torque, work, and power. However, average time to peak torque and angle of peak torque were not reliable.
