Use of wearable inertial sensors for the assessment of spatiotemporal gait variables in children: A systematic review

Abstract Aim: The present study aimed to perform a literature review on the use of wearable inertial sensors for gait analysis of children in clinical practice. Methods: Searches were performed in the MEDLINE, EMBASE, Cochrane Library, and PEDro databases for studies involving children or adolescents submitted to gait analysis with the use of wearable inertial sensors. No restrictions were imposed regarding the date of publication or language. Results: Three hundred twenty articles were retrieved, 14 of which met the eligibility criteria and were selected for the present systematic review. Two independent reviewers assessed the risk of bias and study quality using the ROBINS-I and AXIS scale. The studies included in the present review reported multiple outcomes of kinematic gait assessments calculated from the signals provided by the wearable sensors, performed in a hospital setting, outpatient clinic, and a familiar environment, with several types of pediatric conditions. Conclusion: The findings suggest that wearable sensors are effective for the evaluation of quantitative gait variables in children with different pediatric conditions, enabling an objective analysis that should prove useful in the processes of clinical diagnosis and rehabilitation. However, given the relatively small number of studies published on this topic, it is difficult to make strong recommendations regarding the most appropriate equipment, sensor placement, and outcomes for assessing gait in children.

Evaluation of upper limb movements in children with Down's syndrome: A systematic review.

The aim of the present study was to perform a review of the literature on current quantitative clinical methods for the evaluation of upper limb movements in children and adolescents with Down syndrome, with a focus on describing the variables, protocols, motor function and motor control. METHODS: A survey of PubMed, Scielo, BVS Bireme and PEDro databases using the following key words: upper limb and EMG and Down syndrome; upper limb and kinematics and Down syndrome; upper limb and motion analysis and Down syndrome; movement and upper limb and Down syndrome; upper limb and Down syndrome; reach and Down syndrome. RESULTS: In all, 344 articles and five were selected to compose the present systematic review. No standardization was found among the studies analyzed with regard to data collection, data processing or procedures for the evaluation of the variables. CONCLUSION: A kinematic evaluation is effective for the discussion of the results, but methodological differences among the studies and inconsistent results exert a negative influence on clinical interpretations and the possibility of reproducibility. The standardization of an upper limb movement evaluation protocol using kinematic analysis is important, as it would provide the basis for comparable, reproducible results and facilitate the planning of treatment interventions.

Protocol study for a randomised, controlled, double-blind, clinical trial involving virtual reality and anodal transcranial direct current stimulation for the improvement of upper limb motor function in children with Down syndrome.

INTRODUCTION: Down syndrome results in neuromotor impairment that affects selective motor control, compromising the acquisition of motor skills and functional independence. The aim of the proposed study is to evaluate and compare the effects of multiple-monopolar anodal transcranial direct current stimulation and sham stimulation over the primary motor cortex during upper limb motor training involving virtual reality on motor control, muscle activity, cerebral activity and functional independence. METHODS AND ANALYSIS: A randomised, controlled, double-blind, clinical trial is proposed. The calculation of the sample size will be defined based on the results of a pilot study involving the same methods. The participants will be randomly allocated to two groups. Evaluations will be conducted before and after the intervention as well as 1 month after the end of the intervention process. At each evaluation, three-dimensional analysis of upper limb movement muscle activity will be measured using electromyography, cerebral activity will be measured using an electroencephalogram system and intellectual capacity will be assessed using the Wechsler Intelligence Scale for Children. Virtual reality training will be performed three times a week (one 20 min session per day) for a total of 10 sessions. During the protocol, transcranial stimulation will be administered concomitantly to upper limb motor training. The results will be analysed statistically, with a p value≤0.05 considered indicative of statistical significance. ETHICAL ASPECTS AND PUBLICITY: The present study received approval from the Institutional Review Board of Universidade Nove de Julho (Sao Paulo,Brazil) under process number 1.540.113 and is registered with the Brazilian Registry of Clinical Trials (N° RBR3PHPXB). The participating institutions have presented a declaration of participation. The volunteers will be permitted to drop out of the study at any time with no negative repercussions. The results will be published and will contribute evidence regarding the use of this type of intervention on children.

Effects of a single session of transcranial direct current stimulation on upper limb movements in children with cerebral palsy: A randomized, sham-controlled study.

INTRODUCTION: Motor impairment in children with spastic hemiparetic cerebral palsy (CP) is generally more prominent in the affected upper limb, leading to limitations in hand function stemming from deficiencies in motor coordination and selective motor control as well as muscle weakness, slower execution of movements and deficient integration of sensory-motor information. OBJECTIVE: Determine the effect of a single session of anodal transcranial direct current stimulation (tDCS) combined with functional training on the spatiotemporal variables of upper arm movements in children with spastic hemiparesis. METHOD: A randomized, sham-controlled trial with a blinded evaluator was conducted involving 20 children with CP between 6 and 12 years of age. The spatiotemporal variables of the upper limbs were analyzed by comparing the results of Evaluation 1 (before stimulation) and Evaluation 2 (immediately after stimulation). The protocol consisted of a 20-minute session of functional training of the paretic upper limb combined with tDCS administered over the primary motor cortex of the hemisphere contralateral to the motor impairment at an intensity of 1 mA. The participants were randomly allocated to two groups: experimental group (anodal tDCS) and control group (sham tDCS). RESULTS: Statistically significant (p < 0.05) reductions in total movement duration and returning movement duration were found in both the paretic and non-paretic limbs in the group submitted to active tDCS. No significant differences were found in the control group for any of the variables analyzed. CONCLUSION: A single session of anodal tDCS over the primary motor cortex of the hemisphere ipsilateral to the brain lesion led to momentary motor improvements in both upper limbs of the children with spastic hemiparetic CP analyzed in the present study.

Transcranial direct current stimulation combined with upper limb functional training in children with spastic, hemiparetic cerebral palsy: study protocol for a randomized controlled trial.

BACKGROUND: The aim of the proposed study is to perform a comparative analysis of functional training effects for the paretic upper limb with and without transcranial direct current stimulation over the primary motor cortex in children with spastic hemiparetic cerebral palsy. METHODS: The sample will comprise 34 individuals with spastic hemiparetic cerebral palsy, 6 to 16 years old, classified at level I, II, or III of the Manual Ability Classification System. Participants will be randomly allocated to two groups: (1) functional training of the paretic upper limb combined with anodic transcranial stimulation; (2) functional training of the paretic upper limb combined with sham transcranial stimulation. Evaluation will involve three-dimensional movement analysis and electromyography using the SMART-D 140® system (BTS Engineering) and the FREEEMG® system (BTS Engineering), the Quality of Upper Extremity Skills Test, to assess functional mobility, the Portable Device and Ashworth Scale, to measure movement resistance and spasticity, and the Pediatric Evaluation of Disability Inventory, to evaluate performance. Functional reach training of the paretic upper limb will include a range of manual activities using educational toys associated with an induced constraint of the non-paretic limb during the training. Training will be performed in five weekly 20-minute sessions for two weeks. Transcranial stimulation over the primary motor cortex will be performed during the training sessions at an intensity of 1 mA. Findings will be analyzed statistically considering a 5 % significance level (P ≤ 0.05). DISCUSSION: This paper presents a detailed description of a prospective, randomized, controlled, double-blind, clinical trial designed to demonstrate the effects of combining transcranial direct current stimulation over the primary motor cortex and functional training of the paretic limb in children with cerebral palsy classified at level I, II, or III of the Manual Ability Classification System. The results will be published and evidence found may contribute to the use of transcranial stimulation for this population. TRIAL REGISTRATION: ReBEC RBR-6V4Y3K . Registered on 11 February 2015.

Desenvolvimento motor em RN prematuros / Motor development of premature newborns

A prematuridade e o extremo baixo peso estão associados a um baixo desenvolvimento cognitivo, além de atraso no desenvolvimento motor. Os fisioterapeutas são os primeiros avaliadores e provedores de cuidados na identificação e no tratamento dessas crianças e necessitam de uma avaliação sensível, para detectar alterações e reprodutível, além de conhecer prováveis fatores que se correlacionem com atraso no desenvolvimento neuropsicomotor (ADNPM) nesta população. O objetivo foi conhecer possíveis fatores presentes ao nascimento e durante o follow-up de crianças pré-termo que se correlacionem com o ADNPM. Estudo retrospectivo de análise de prontuários de crianças acompanhadas no follow-up, avaliadas pela AIMS e apresentavam registro completo do nascimento e período de internação. Foram selecionados 37 e 11 prontuários incluídos para análise. A média de idade das crianças avaliadas foi de 8,63 ± 2,11 meses, a idade gestacional média foi 30 ± 3,06 semanas e o peso ao nascimento de 1.331 ± 496,53 gramas. Houve uma correlação moderada e positiva entre a pontuação na AIMS e o perímetro cefálico (PC) ao nascimento (r=0,62 e p=0,04). O PC e o peso se encontravam abaixo e no percentil 5, respectivamente, no momento da avaliação em 70% das crianças. RNPT de muito baixo peso podem apresentar ADNPM, baixo desenvolvimento pondero-estatural e tempo prolongado de suporte ventilatório e internação na UTI. Quanto menor o PC ao nascimento e se este permanecer abaixo do percentil 5 após e sexto mês, provavelmente o ADNPM estará presente no primeiro ano de vida.

Effect of posture-control insoles on function in children with cerebral palsy: randomized controlled clinical trial.

INTRODUCTION: Cerebral palsy (CP) is a posture and movement disorder and different therapeutic modalities, such as the use of braces, have sought to favor selective motor control and muscle coordination in such patients. The aim of the proposed study is to determine the effect of the combination of posture-control insoles and ankle-foot orthoses (AFOs) improving functional limitation in children with CP. METHODS/DESIGN: The sample will be composed of 24 children with CP between four and 12 years of age. After the signing of the statement of informed consent, the children will be randomly allocated to two groups: a control group using AFOs alone and an experimental group using both posture-control insoles and AFOs. Evaluations will be performed on five occasions: without any accessory (insoles or AFOs), immediately after, one month after, six months after and one year after AFOs or insole and AFOs use. The evaluation will involve the analysis of gait, static and functional balance, mobility and hypertonia. The three-dimensional assessment of gait will involve the eight-camera SMART-D SMART-D 140® system (BTS Engineering), two Kistler force plates (model 9286BA) and an eight-channel, wireless FREEEMG® electromyography (BTS Engineering). Static balance will be assessed using a Kistler force plate (model 9286BA). Clinical functional balance and mobility will be assessed using the Berg Balance Scale, Timed Up-and-Go Test and Six-Minute Walk Test. The posture-control insoles will be made of ethylene vinyl acetate, with thermal molding for fixation. The fixed orthoses will be made of polypropylene and attached to the ankle region (AFO). The results will be analyzed statistically, with the level significance set to 5% (p < 0.05). TRIAL REGISTRATION NUMBER: RBR6d342s (http://www.ensaiosclinicos.gov.br/news/).

Alteração espirométrica em crianças com mielomeningocele é dependente do nível de lesão funcional / Spirometric abnormalities in children with myelomeningocele is dependent of the level of functional injury

Objetivo: Avaliar a função pulmonar de crianças com mielomeningocele (MMC) de diferentes níveis de lesão funcional comparados a controles saudáveis pareados por idade e sexo. Material e método: Este foi um estudo caso-controle, no qual foi selecionada apenas uma criança por nível funcional de lesão e com função cognitiva preservada, e controles de crianças saudáveis pareados por idade e gênero ao grupo deMMC. Medidas antropométricas e espirométricas de função pulmonar foram obtidas de ambos os casose controles de MMC. Resultados: Todas as crianças com MMC apresentaram reduzido estado nutricional segundo os índices recomendados pela OMS. Foi observada presença de distúrbio ventilatório restritivo leve nas crianças com nível de lesão torácica (CVF = 0,65 por centoprev) e lombar-alta (CVF = 0,69 por centoprev), e apesar de dentro dos limites da normalidade, as crianças com MMC com níveis inferiores de lesão apresentaram valores espirométricos menores do que seus respectivos controles. Houve correlação negativa perfeita entre a capacidade vital forçada e o nível de lesão funcional das crianças com MMC. Conclusão: Crianças com MMC apresentam reduzidos valores de função pulmonar quando comparados aos controles saudáveis, sobretudo os com níveis de lesão funcional elevada, os quais demonstraram distúrbio ventilatório restritivo. A fisioterapia respiratória deve ser incorporada na avaliação e segmento das crianças com MMC, coadjuvante à fisioterapia motora, especialmente naquelas acometidas com níveis de lesões mais elevadas.
