RESUMO
OBJECTIVE: To describe the urological outcomes in children with congenital Zika syndrome (CZS) and investigate the relationship between clinical and urological findings in this population. METHODS: This cross-sectional study involved children with CZS followed up by a referral centre for children with microcephaly in the state of Paraiba in northeast Brazil. The urological evaluation included clinical history, urine culture results, ultrasonography of the urinary tract, and urodynamic evaluation, following the protocol proposed by Costa Monteiro et al. (2017). Descriptive statistical analysis was performed in addition to association and correlation tests, considering clinical and urodynamic variables. RESULTS: Among the 88 children with CZS (35.5 ± 5.5 months), 97.7% had microcephaly, and 51% presented urinary tract infection (UTI) confirmed with clinical history and lab tests. The number of confirmed UTI episodes varied from one to 14 per child. The urodynamic evaluation confirmed the presence of an overactive bladder in 78 children and incomplete voiding in 50. Urodynamic findings were associated with the number of confirmed UTI episodes, child's sex, and actual weight, in addition to the use of anticonvulsant and myorelaxant drugs. CONCLUSIONS: UTIs were confirmed in most children. Other urological outcomes observed were overactive bladder and low bladder capacity, which were associated with the number of confirmed UTI episodes, use of anticonvulsants and myorelaxants, and the child's sex and weight. These are treatable conditions, and it is paramount that paediatricians, neonatologists, and infectious disease specialists are aware of them to make clinical decisions and help reduce the risk of renal damage and other morbidities.

AIM: To evaluate the effects of neurodevelopmental treatment (NDT) in children with congenital Zika syndrome (CZS). METHODS: This prospective, interventional cohort study involved children with CZS undergoing follow-up at a specialist centre in northeastern Brazil. The duration of the proposed NDT protocol was 1 year, with 45-min sessions delivered one to five times weekly. Motor function, weight, height, head circumference and the incidence of comorbidities were evaluated in children before protocol initiation and then at 3, 6 and 12 months of treatment. RESULTS: Thirty children were evaluated (age mean 30.1 ± 3 months). Motor function improved from baseline to 6 months (P = 0.001). No difference in weight and head circumference z-score (P = 0.51 and P = 0.29, respectively), but an increase in height z-score (P < 0.001) was observed over the evaluation period. There was a reduction in the incidence of upper respiratory tract infections, pneumonia and urinary tract infections over the follow-up period. CONCLUSIONS: NDT proved to be a viable treatment approach that can improve motor function and reduce the incidence of comorbidities in children with CZS, while having no harmful effects on their growth.

OBJECTIVE: To investigate the effect of intensive physiotherapy training on the motor function of children with congenital Zika syndrome (CZS). DESIGN: A retrospective cohort study. SETTING: A support center for children with microcephaly. PARTICIPANTS: Children (N=7) aged 14 to 18 months old who were diagnosed with CZS and previously monitored more than 1 year. INTERVENTIONS: A 2-stage protocol repeated uninterruptedly for 1 year. In the first stage, the children were submitted to 1 hour of conventional physiotherapy and 1 hour of suit therapy 5 times a week for 4 weeks. The second stage consisted of 1 hour of suit therapy 3 times a week for 2 weeks. MAIN OUTCOME MEASURES: Gross motor function measure (GMFM) and body weight. RESULTS: Six evaluations were conducted approximately 3 months apart. An increase in the overall GMFM score was observed between the first and second (P=.046), first and third (P=.018), first and fourth (P=.018), first and fifth (P=.043), and first and sixth evaluations (P=.018). Differences in the scores of the individual GMFM dimensions were found only for dimension A (lying and rolling) between the first and fourth evaluations (P=.027) and for dimension B (sitting) between the first and third (P=.018), first and fourth (P=.046), and first and sixth evaluations (P=.027). No difference was found in body weight between the first and sixth evaluations (P=.009). During follow-up, only 1 child required hospitalization, and another had increased irritability. CONCLUSIONS: Children with CZS were able to perform 2 hours of motor physiotherapy daily with no serious complications, resulting in an increase or stabilization in GMFM scores.

AIM: To evaluate gross motor function and associated factors in children with congenital Zika syndrome (CZS). METHOD: Fifty-nine children (30 males, 29 females) with CZS at a mean (SD) age of 14.7 (3.9), months (range 5-29mo) were evaluated using the Gross Motor Function Measure (GMFM) and classified according to the Gross Motor Function Classification System (GMFCS). Neurological damage was evaluated by neuroimaging. The mothers' sociodemographic characteristics and general data on the children were obtained from interviews with the mothers and from the children's medical records. Correlational and multiple regression analyses were performed to identify factors associated with these children's motor function. RESULTS: In 81% of the children, motor function impairment was severe, classified as GMFCS level V. The overall GMFM score ranged from 5 to 210 (median 18; interquartile range 11), with only four children receiving scores in the D and E dimensions. The factors found to affect motor function were the presence of severe malformations of cortical development and small head circumference at birth. INTERPRETATION: Although motor impairment may be mild in some children, it is generally severe. Severe malformations of cortical development and small head circumference at birth were factors associated with poorer motor function, reflecting the greater severity of brain damage. WHAT THIS PAPER ADDS: Motor impairment is severe in most children with congenital Zika syndrome (CZS). Motor skills are adequate or close to adequate for age in 7% of children with CZS. Severe malformations of cortical development are associated with poor motor control. Small head circumference at birth is also associated with poor motor control.
FUNCIÓN MOTORA EN NIÑOS CON SÍNDROME DE ZIKA CONGÉNITO: OBJETIVO: Evaluar la función motora gruesa y los factores asociados en niños con síndrome de Zika congénito (CZS). MÉTODO: Cincuenta y nueve niños (30 varones, 29 mujeres) con CZS a una edad media (DE) de 14,7 (3,9), meses (rango 5-29 meses) se evaluaron utilizando la Medida de la función motora gruesa (GMFM) y se clasificaron de acuerdo con el Sistema de Clasificación de la Función Motora Gruesa (GMFCS). El impacto estructural neurológico se evaluó mediante neuroimagen. Las características sociodemográficas de las madres y los datos generales de los niños se obtuvieron en entrevistas con las madres y de los registros médicos de los niños. Se realizaron análisis de regresión correlacional y múltiple para identificar los factores asociados con la función motora de estos niños. RESULTADOS: En el 81% de los niños, el deterioro de la función motora fue grave, clasificado como nivel V de GMFCS. El puntaje general de GMFM varió de 5 a 210 (mediana 18; rango intercuartil 11), y solo cuatro niños recibieron puntajes en las dimensiones D y E. Los factores que afectaron la función motora fueron la presencia de malformaciones graves del desarrollo cortical y la circunferencia de la cabeza (microcefalia) al nacer. INTERPRETACIÓN: Aunque el deterioro motor puede ser leve en algunos niños, generalmente el impacto de CZS es grave. Las malformaciones graves del desarrollo cortical y la microcefalia al nacer fueron factores asociados con una función motora más limitada, lo que refleja la mayor gravedad del daño cerebral.
FUNÇÃO MOTORA EM CRIANÇAS COM SÍNDROME CONGÊNITA DE ZIKA: OBJETIVO: Avaliar a função motora grossa e fatores associados em crianças com síndrome congênita de Zika (SCZ). MÉTODO: Cinquenta e nove crianas (30 do sexo masculino, 29 do sexo feminino) com SCZ com uma média (DP) de idade de 14,7 (3,9) meses (variação 5-29m) foram avaliadas usando a Medida da Função Motora Grossa (GMFM) e classificadas de acordo com o Sistema de Classificação da Função Motora Grossa (GMFCS). O dano neurológico foi avaliado por neuroimagem. As características sócio-demográficas da mãe e dados gerais sobre as crianças foram obtidos em entrevistas com as mães e a partir dos prontuários medicos. Análises de correlação e de regressão múltipla foram realizadas para identificar fatores associados com a função motora destas crianças. RESULTADOS: Em 81% das crianças, o comprometimento da função motora era severo, classificao como nível GMFCS V. O escore geral da GMFM various de 5 a 210 (mediana 18; intervalo interquartil 11), com apenas quatro crianças recebendo pontuações nas dimensões D e E. Os fatores que afetaram a função motora grossa foram a presença de malformações severas no desenvolvimento cortical, e o pequeno perímetro cefálico ao nascimento. INTERPRETAÇÃO: Embora a deficiência motora possa ser leve em algumas crianças, em geral ela é severa. Malformações severas no desenvolvimento cortical e o pequeno perímetro cefálico foram fatores associados com pior função motora, refletindo a maior severidade do dano cerebral.

OBJECTIVE: To describe obstetric and perinatal outcomes in cases of congenital Zika syndrome (CZS). METHODS: A dual prospective and retrospective cohort study involving 102 pairs of mothers and fetuses/children with CZS whose infection was confirmed by testing for the Zika virus in amniotic fluid, umbilical cord blood, and fragments from the placenta of the newborn infant (confirmed CZS), or by intrauterine imaging tests (neurosonography), and/or postnatal computed tomography (presumed CZS). RESULTS: Suspicion of CZS was investigated by ultrasonography during pregnancy in 52.9% of cases. The principal prenatal imaging findings were ventriculomegaly (43.1%) and microcephaly (42.2%). Median gestational age at delivery was 39 weeks, with 15.7% being premature. Mean head circumference at birth was 30.0 ± 2.3 cm, with 66% of cases being classified as having microcephaly. Arthrogryposis was found in 10 cases (9.8%). There were no fetal deaths; however, nine neonatal deaths were recorded, and three autopsies were performed. CONCLUSION: Neonatal mortality was high, almost 10%. Regarding the abnormalities of CZS, microcephaly, although common, was not present in all cases and intracranial findings need to be taken into consideration for diagnosis. Therefore, ultrasound screening during pregnancy should be systematized and expanded in endemic zones.

OBJECTIVE: To investigate the effects of gait training with body weight support (BWS) on a treadmill versus overground in individuals with chronic stroke. DESIGN: Randomized controlled trial. SETTING: University research laboratory. PARTICIPANTS: Individuals (N=28) with chronic stroke (>6mo from the stroke event). INTERVENTIONS: Participants were randomly assigned to receive gait training with BWS on a treadmill (n=14) or overground (n=14) 3 times a week for 6 weeks. MAIN OUTCOME MEASURES: Gait speed measured using the 10-meter walk test, endurance measured using the 6-minute walk test, functional independence measured using the motor domain of the FIM, lower limb recovery measured using the lower extremity domain of the Fugl-Meyer assessment, step length, step length symmetry ratio, and single-limb support duration. Measurements were obtained at baseline, immediately after the training session, and 6 weeks after the training session. RESULTS: At 1 week after the last training session, both groups improved in all outcome measures except paretic step length and step length symmetry ratio, which were improved only in the overground group (P=.01 and P=.01, respectively). At 6 weeks after the last training session, all improvements remained and the treadmill group also improved paretic step length (P<.001) but not step length symmetry ratio (P>.05). CONCLUSIONS: Individuals with chronic stroke equally improve gait speed and other gait parameters after 18 sessions of BWS gait training on either a treadmill or overground. Only the overground group improved step length symmetry ratio, suggesting a role of integrating overground walking into BWS interventions poststroke.

The Zika virus (ZIKV) epidemic had a sanitary, psychosocial, and economic impact on individuals of reproductive age. The primary concern revolved around infection during pregnancy due to possible vertical transmission and its association with adverse fetal and infant outcomes, known as Congenital Zika Syndrome (CZS). This qualitative study employs phenomenology and grounded theory. This study includes interviews with 98 women, some pregnant during the ZIKV epidemic in Brazil, Colombia, and Puerto Rico, who had children with CZS or without diagnosed neurological impairment. Additionally, the study included a group of women who were pregnant during the COVID-19 pandemic in these same countries. In both groups, interviewees had varying levels of knowledge about ZIKV. The study found that messages conveyed through the media tended to be alarmist, in contrast to the information provided by healthcare professionals, which was considered more trustworthy. Pregnant women during the ZIKV epidemic reported receiving their ZIKV and CSZ infection diagnoses late, either during or after childbirth. The study underscores the needs of pregnant women in high-risk scenarios, the importance of health education processes, and the necessity to reinforce communication and continuing education.
A epidemia do vírus Zika (ZIKV) teve impacto sanitário, psicossocial e econômico sobre pessoas em idade reprodutiva. A principal preocupação foi a infecção durante a gravidez devido a possível transmissão vertical e sua associação com resultados fetais e infantis adversos, conhecida como síndrome congênita associada à infecção pelo Vírus Zika (SCZ). Este estudo qualitativo utiliza a fenomenologia e a teoria fundamentada. O estudo inclui entrevistas com 98 mulheres, parte grávida durante a epidemia de ZIKV no Brasil, Colômbia e Porto Rico e que tiveram filhos com SCZ ou sem comprometimento neurológico diagnosticado. Além disso, o estudo inclui um grupo de mulheres grávidas durante a pandemia de COVID-19 nos mesmos países. Em ambos os grupos, as entrevistadas tinham diferentes níveis de conhecimento sobre ZIKV. O estudo constatou que as mensagens veiculadas por meio da mídia eram alarmistas; em contraste com as informações fornecidas por profissionais de saúde, consideradas mais confiáveis. Mulheres gestantes durante a epidemia do ZIKV relataram ter recebido seu diagnóstico de infecção por ZIKV e SCZ tardiamente ou após o parto. O estudo destaca as necessidades das mulheres grávidas em cenários de alto risco, a importância de processos de educação em saúde e a necessidade de reforçar a comunicação e a educação continuada.
RESUMO
Providing accurate, evidence-based information to women with Zika infection during pregnancy was problematic because of the high degree of uncertainty in the diagnosis of the infection and the associated risk. The 2015-17 Zika virus epidemic overwhelmingly affected women in countries with limited access to safe abortion. Understanding women's perspectives on risk communication during pregnancy in the context of an emerging pathogen can help inform risk communication in response to future outbreaks that affect fetal or child development. We conducted a cross-sectional qualitative interview study with 73 women from 7 locations in Brazil, Colombia, and Puerto Rico to understand women's experiences of Zika virus (ZIKV) test and outcome-related communication during the ZIKV pandemic. We used thematic analysis to analyze the in-depth interviews. Participants in Brazil and Colombia reported that the healthcare system's lack of preparation and organization in communicating ZIKV test results and associated adverse outcomes led to their feeling abandoned and alone in confronting the challenges of a ZIKV-affected pregnancy. In contrast, participants in Puerto Rico reported that the regular testing schedules and clear, well-planned communication between the care team and between providers and pregnant women helped them to feel they could prepare for a ZIKV-affected pregnancy. Communication of the risk associated with an emerging pathogen suspected to affect pregnancy and developmental outcomes is a fraught issue. Public health authorities and healthcare providers should work together in the interpandemic period to understand families' preferences for risk communication during pregnancy in the presence of uncertainty and develop a community-informed plan for risk communication.
RESUMO
This article describes the impact of social distancing during the COVID-19 pandemic on the motor function and growth of children with congenital Zika syndrome (CZS). Children's motor function, weight, height and joint range of movement (ROM) were evaluated before the onset of the pandemic and soon after their return to face-to-face activities at a rehabilitation center. Fifty-two children (Mean 46.07 months, SD 3.76 months) were assessed. Results showed a reduction in proportion of children with adequate body mass index (p = .04), an increase in proportion with adequate height (p < 0.001), deterioration in gross motor function in children with severe motor impairment (p < .01), and a reduction in the maximum ROM for shoulder (p < .01) and wrist flexion (p = .046), elbow (p = .01), knee (p = .03) and ankle extension (p < .01), and an increase in hip flexion (p = .04). The social distancing period appears to have contributed to important losses in motor function and joint mobility of children with CZS; however, this period of time appeared to have less impact on their growth.

PURPOSE: To provide a detailed description of the development of the first case of congenital Zika syndrome (CZS) to be reported in the literature worldwide. CASE DESCRIPTION: This report describes the case of a child with CZS monitored from pregnancy until four years of age, with periodic evaluations of head circumference, weight, height, motor function according to the Gross Motor Function Measure (GMFM-88), and the occurrence of comorbidities. OUTCOMES: The child's birth weight and length were normal (z-score = 1.1 and -1.95, respectively), while head circumference was below the expected value (z-score = -3.15). At 48 months, head circumference reached 43 cm (z-score = -4.48). During daily home physiotherapy sessions, the child achieved developmental milestones, standing unsupported at 17 months, with a GMFM-88x score of 137. With specialist therapy, the child walked independently at 36 months and a total GMFM-66 score of 214 was achieved by 42 months. In the four years of follow-up, the child was hospitalized four times for different reasons. No convulsive seizures occurred. CONCLUSIONS: Despite severe neurological impairment, the child's weight and height are adequate for age, with motor and cognitive function improving over the first four years of life.
RESUMO
This study examined the effects of the support surface (i.e., treadmill or ground) and the quantity of body weight unloading provided by a partial body weight support (PBWS) system on the spatiotemporal gait characteristics of individuals with stroke. Fifteen individuals, aged 57.2 ± 9.8 years, with chronic stroke walked on a treadmill and on the ground with 0%, 10%, and 20% of PBWS. Inertial sensors placed on the participants' feet registered 3-D acceleration and 3-D angular velocity during walking, and some gait parameters were calculated. Overall, individuals with stroke walked with shorter and slower strides and spent more time in contact with the support surface when walking on the treadmill compared to when walking on the ground. The duration of double limb support decreased when the percentage of PBWS increased. Stride length and speed were more variable in the paretic limb than in the non-paretic limb. Treadmill walking was more consistent and less similar to ordinary walking than walking on the ground. The gait pattern of individuals with stroke was modulated according to the support surface on which walking was performed, and the use of a PBWS system seems suitable to develop walking proficiencies on a daily basis.

Aim: To identify abnormalities in muscle tone and motor function associated with congenital Zika syndrome (CZS).Method: A cross-sectional observational study involving 96 children (55 males) with CZS at a mean (SD) age 35.2 ± 2.9 months. Children's muscle tone was investigated using the pull to sit, scarf sign, shoulder suspension and ventral suspension tests and the modified Ashworth scale (MAS). Motor impairment was determined using the Gross Motor Function Classification System (GMFCS) and body segments most affected with motor impairment.Results: 58 (60,5%) children tested positive for ≥1 maneuver used to evaluate muscle tone, while 38 (39.5%) tested negative in all the tests. MAS score was >0 for at least one of the appendicular muscles in 91 children (94.8%). In 88 children (91.7%), all four limbs were affected.Conclusion: Findings suggestive of axial hypotonia and appendicular hypertonia associated with severe motor impairment were prevalent in children with CZS.

BACKGROUND: To better understand gait initiation in individuals with stroke and suggest possible training strategies, we compared the gait initiation of individuals with stroke and age-matched controls, and we examined the influence of different amounts of body weight support (BWS) during the execution of gait initiation in individuals with stroke. MATERIALS AND METHODS: Twelve individuals with stroke and 12 age-matched controls initiated gait after a verbal command at a self-selected and comfortable speed, and individuals with stroke also initiated gait wearing a harness with 0%, 15%, and 30% of BWS. Length and velocity of the first step, distance between heels, and weight bearing in both lower limbs in the initial position were calculated. We also assessed the displacement and average velocity of the center of pressure (CoP) in the medial-lateral (ML) and anterior-posterior (AP) directions in 3 distinct sections during gait initiation, which correspond to the CoP position toward the swing limb, stance limb and progression line, respectively. RESULTS: Individuals with stroke presented shorter and slower step, shorter and slower CoP-ML and CoP-AP toward swing limb and Cop-ML towards stance limb, and longer and faster CoP-AP toward stance limb compared to their peers. The BWS lead individuals with stroke to decrease step length and to increase CoP-ML displacement and average velocity toward stance limb. CONCLUSION: Individuals with stroke present impairments in executing gait initiation mainly during the preparation period and the employment of an overground BWS system promotes a better performance. These results suggest that BWS is a functional strategy that enables individuals with stroke to modulate gait initiation and it could be adopted for gait intervention.

Individuals with stroke often present functional impairment and gait alteration. Among different aspects, intralimb coordination of these individuals is one of the key points that should be considered before implementing any gait intervention protocol. The purpose of this study was to investigate the effects of stroke on intralimb gait coordination of the lower limbs using a vector coding technique. Twenty-five individuals with stroke and 18 non-disabled individuals (control), between 46 and 71â¯years old, participated in this study. A computerized analysis system registered data from reflective markers placed on specific body landmarks to define thigh, shank, and foot of both body sides, as participants walked at self-selected comfortable speed. Coordination modes, such as in-phase, anti-phase, proximal-segment-phase, and distal-segment-phase, and variability of thigh-shank, and shank-foot were analyzed for the paretic, non-paretic and control limbs during the stance and swing periods, and the entire gait cycle using the vector coding technique. During the stance period, individuals with stroke presented higher frequency of thigh-phase and lower frequency of shank-phase for the thigh-shank coupling and higher frequency of shank-phase for the shank-foot coupling compared to non-disabled controls, indicating that the proximal segment of each pair leads the movement. During the swing period, the paretic limb presented higher frequency for in-phase than non-paretic and control limbs for the thigh-shank coupling. Adaptations in the non-paretic limb were observed in the swing period, with higher frequency than paretic and control limbs in the thigh-phase for the thigh-shank coupling, and higher frequency than the paretic limb in the foot-phase for the shank-foot coupling. No differences in coordination variability were found between paretic, non-paretic, and control limbs. The vector coding technique constitutes a useful tool for identifying gait alterations in intralimb coordination of individuals with stroke. Our coordination results demonstrate a shift from distal to more proximal control during the stance phase in both legs for the individuals with stroke and an inability to decouple segment coordination during the swing phase in the paretic limb. The results indicate that it is more suitable to consider the stance and swing periods separately instead of considering the entire gait cycle to investigate intralimb gait coordination of individuals with stroke.

Understanding the changes induced by body weight support (BWS) systems when non-disabled adults walk can help develop appropriate rehabilitation protocols. The purpose of this study was to investigate spatial-temporal gait alterations during walking with BWS on a treadmill and over the ground. Fourteen non-disabled young adults (including seven women) walked over the ground and on a treadmill with 0%, 10%, and 20% of BWS at 80% of their self-selected comfortable walking speed (baseline). The stride length and speed, step length, and stance and double-limb support durations were calculated and compared among the different conditions. The non-disabled adults modulated their spatial-temporal gait parameters according to the surface and percentage of BWS. They walked with shorter and slower strides and shorter steps and spent more time in contact with the support surface as they walked on the treadmill than as they did over the ground. Walking on the treadmill promoted less variability and a higher rate of change than did walking over the ground. Both the surface and amount of BWS should be taken into consideration when using BWS systems for (re)learning and/or reestablishing gait.

RESUMO
BACKGROUND: Locomotor adaptation has been suggested as a way to improve gait symmetry in individuals post-stroke. Most perturbation methods utilize costly, specialized equipment. The use of a unilateral leg weight may provide a low cost, clinically translatable alternative. Furthermore, previous studies have suggested that adaptation context may affect movement outcomes. The purpose of this study was to assess the ability of a unilaterally applied ankle weight to drive locomotor adaptation and determine the effect of context (treadmill versus overground) in young, non-disabled participants. METHODS: Eighteen young non-disabled adults were randomly assigned to receive 10min of walking on a treadmill with a weight (TG), overground with a weight (OG) or as a control on a treadmill/overground without a weight (CG). Outcomes measured before, during and after adaptation were: step length symmetry, single limb support symmetry and gait speed. RESULTS: After adding the weight, single limb support immediately became asymmetrical for all participants without changes in step length symmetry. After walking for 10min, TG step length became asymmetrical. After weight removal, both TG and OG had increased step length asymmetry. TG decreased single limb support asymmetry while OG did not. After walking overground without the weight, walking parameters eventually returned to baseline in both weighted groups. The control group showed no changes. CONCLUSION: A unilaterally applied ankle weight appears able to cause gait adaptation in young, non-disabled participants. However different adaptive changes in the gait pattern are made by the nervous system when the perturbation is applied in different contexts.

A Paralisia Cerebral (PC) engloba um grupo de desordens do movimento e da postura resultantes de uma lesão não progressiva no sistema nervoso. Diversas abordagens fisioterapêuticas vêm sendo propostas para o tratamento de indivíduos com PC, dentre elas o uso de vestes terapêuticas. Sendo assim, a presente revisão teve como objetivo avaliar os efeitos das vestes terapêuticas na reabilitação de crianças com PC, destacando seus benefícios e possíveis limitações. Tratou-se de uma revisão integrativa da literatura realizada nas bases SciELO, Lilacs, Pubmed, Science Direct e PEDro, por meio do descritor "Paralisia Cerebral" e das palavras-chave "AdeliSuit", "PediaSuit", "TheraSuit". Após o levantamento bibliográfico, foram selecionados 11 estudos envolvendo crianças com idade entre um e 15 anos, os quais descreveram o uso das vestes terapêuticas AdeliSuit, TheraSuit e PediaSuit. Todos os estudos apresentaram efeitos favoráveis ao uso das vestes para função motora das crianças avaliadas. Também houveram relatos de melhora na funcionalidade, velocidade e qualidade da marcha e equilíbrio. Apenas quatro estudos compararam programas de reabilitação envolvendo vestes terapêuticas e outras abordagens, os quais apresentaram resultados controversos. Os achados demonstraram resultados favoráveis ao uso das vestes terapêuticas em indivíduos com diagnóstico de PC, apesar de poucas evidências quanto a sua superioridade sobre outras abordagens. (AU)
Cerebral Palsy (CP) is a group of movement and posture disorders resulting from nervous system non-progressive injury. Several physiotherapy approaches have been proposed to individuals with CP treatment, including the use of therapeutic suits. Thus, the present review aimed to assess the effects of therapeutic suits on children with CP rehabilitation, highlighting their benefits and possible limitations. It was an integrative literature review carried out on SciELO, Lilacs, Pubmed, Science Direct and PEDro databases, using tdescriptor "Cerebral Palsy" and keywords "AdeliSuit", "PediaSuit", "TheraSuit". After bibliographic search, 11 studies were selected involving children aged between one and 15 years old, which described the use of therapeutic suits: AdeliSuit, TheraSuit and PediaSuit. All studies showed positive effects therapeutic suits use during rehabilitation for motor function. Improvements in functionality, speed and quality of gait and balance were also reported. Only four studies compared rehabilitation programs involving therapeutic suits and other therapeutic approaches, which showed controversial results. Those findings demonstrated favorable results for the use of therapeutic suits during rehabilitation programs in individuals with CP, despite little evidence regarding their superiority over other approaches.

BACKGROUND: Studies that evaluate gait rehabilitation programs for individuals with stroke often consider time since stroke of more than six months. In addition, most of these studies do not use lesion etiology or affected cerebral hemisphere as study factors. However, it is unknown whether these factors are associated with post-stroke motor performance after the spontaneous recovery period. OBJECTIVE: To investigate whether time since stroke onset, etiology, and lesion side is associated with spatiotemporal and angular gait parameters of individuals with chronic stroke. METHODS: Fifty individuals with chronic hemiparesis (20 women) were evaluated. The sample was stratified according to time since stroke (between 6 and 12 months, between 13 and 36 months, and over 36 months), affected cerebral hemisphere (left or right) and lesion etiology (ischemic and hemorrhagic). The participants were evaluated during overground walking at self-selected gait speed, and spatiotemporal and angular gait parameters were calculated. Results Differences between gait speed, stride length, hip flexion, and knee flexion were observed in subgroups stratified based on lesion etiology. Survivors of a hemorrhagic stroke exhibited more severe gait impairment. Subgroups stratified based on time since stroke only showed intergroup differences for stride length, and subgroups stratified based on affected cerebral hemisphere displayed between-group differences for swing time symmetry ratio. CONCLUSION: In order to recruit a more homogeneous sample, more accurate results were obtained and an appropriate rehabilitation program was offered, researchers and clinicians should consider that gait pattern might be associated with time since stroke, affected cerebral hemisphere and lesion etiology.

BACKGROUND: Evaluate the effects of additional load (5% and 10% of body weight) with treadmill gait training on the motor aspects in Parkinson's disease (PD). METHODS: Randomized controlled single-blind trial with 30 individuals with PD. The volunteers were divided into three groups (treadmill with 0%, 5% or 10% load), where Unified Parkinson's Disease Rating Scale was applied. Treadmill gait training was conducted over 4 consecutive weeks, with three weekly sessions of 30 min each. RESULTS: There was a significant reduction in all groups in the time factor for motor function (F = 12.92; P = 0.001) and postural instability (F = 11.23; P = 0.002). No significant difference was observed in group × time interaction (F < 1.76; P > 0.19). CONCLUSION: The treadmill comprises an effective therapy for people with PD, for important motor aspects such as motor function and postural instability. Additional load had no influence on results.
