Functioning profile and related impairments of children and adolescents with cerebral palsy - PartiCipa Brazil preliminary results.

Background: Limited information is available about functioning and related impairments of children and adolescents with Cerebral Palsy (CP) in low- and middle-income countries (LMIC) like Brazil. The aim of this study is to describe the characteristics, functioning, and impairments of Brazilian children and adolescents with CP.

Methods: Cross-sectional preliminary study as part of the PartiCipa Brazil multicentered cohort study.

Gross Motor Family Report: Refinement and evaluation of psychometric properties.

Aim: To refine the Gross Motor Family Report (GM-FR) using parents' input and to evaluate its psychometric properties.

Method: In this measurement study, 12 parents of children and adolescents with cerebral palsy (CP), aged 2 to 18 years, classified in all levels of the Gross Motor Function Classification System (GMFCS), were interviewed about their experience completing the GM-FR (content validity). Parents' feedback was used to refine the measure which was then completed by 146 families to evaluate internal consistency, and discriminative and concurrent validity.

Development of the Gross Motor Function Family Report (GMF-FR) for Children with Cerebral Palsy.

To describe the initial steps in the development of a family-completed, modified version of the Gross Motor Function Measure (GMFM-88) to report gross motor function of young people with cerebral palsy in their natural environments. Development of the Gross Motor Function - Family Report (GMF-FR) was based on expert opinion involving 13 experienced clinicians and researchers, in four steps: (1) item identification to target items that reflect functional gross motor performance; (2) item selection; (3) critical analysis of the items; and (4) item and scoring modification. Several modifications to existing items and scoring were made, including wording changes to optimize ease of families' understanding, the addition of photographs to illustrate all items, changes to the items to enable use of furniture instead of specialized equipment, and modifications to scoring criteria to ensure a focus on functional motor skills.

Desenvolvimento de crianças, adolescentes e jovens adultos com Paralisia Cerebral de acordo com a CIF? Uma revisão do escopo.

A CIF pode ser usada para mapear uma série de desfechos por meio de estudos de desenvolvimento. Os principais desfechos investigados em crianças com PC foram atividade e estrutura e função corporal. Pouco tem sido explorado os desfechos de participação e fatores contextuais ao longo do tempo.

Development of children, adolescents, and young adults with cerebral palsy according to the ICF: A scoping review.

Aim: To identify and provide a descriptive overview of the development of children, adolescents, and young adults with cerebral palsy (CP) in longitudinal studies; and map areas of focus according to the components of the World Health Organization's International Classification of Functioning, Disability, and Health (ICF).

Method: Longitudinal studies of the development of children, adolescents, and/or young adults with CP were included in this scoping review. A search for eligible studies was conducted in the databases MEDLINE, PubMed, LILACS, EMBASE, Cochrane, CINAHL, and Scopus, and was restricted to the years 2002 to 2022.

Preterm and writhing movements: is it possible to predict fidgety movements in preterm infants?

Background: Preterm infants who do not have fidgety movements at 3 months of corrected age have up to ten times greater risk of developing cerebral palsy or other alterations in motor development, compared to infants who exhibit such movements. The General Movements Assessment (GMA) is a validated tool that may predict the fidgety movement period.

Objective: This study aimed to describe the trajectory of the General Movements Assessment (GMA) during the preterm and writhing movements periods in preterm infants and determine the best time point to predict the fidgety movements period.

Study protocol: functioning curves and trajectories for children and adolescents with cerebral palsy in Brazil - PartiCipa Brazil.

Background: Gross motor development curves for children with Cerebral Palsy (CP), grouped by Gross Motor Function Classification System (GMFCS) levels, help health care professionals and parents to understand children's motor function prognosis. Although these curves are widely used in Brazil to guide clinical decision-making, they were developed with Canadian children with CP. Little is known about how these patterns evolve in children and adolescents with CP in low-income countries like Brazil.

Effects of baby walker use on the development of gait by typically developing toddlers.

Background: Decisions about the use of baby walker are in part predicated on caregivers´ beliefs about its effect on gait development. The actual effects of baby walkers, however, have not been established.

Research Question: What are the effects of the use of baby walker prior to gait onset on age of acquisition of this milestone and on early walking kinematics?

Methods: Thirty-two toddlers, 16 in the baby walker group (BWG) and 16 in the non-users group (BWNG), were evaluated in the week of gait acquisition and monthly up to six months after this event.

Assessment of gait in toddlers with normal motor development and in hemiplegic children with mild motor impairment: a validity study.

Background: The optimization of gait performance is an important goal in the rehabilitation of children with cerebral palsy (CP) who present a prognosis associated with locomotion. Gait analysis using videos captured by digital cameras requires validation.

Objective: To evaluate the validity of a method that involves the analysis of videos captured using a digital camera for quantifying the temporal parameters of gait in toddlers with normal motor development and children with CP.

Impact of leg length and body mass on the stride length and gait speed of infants with normal motor development: a longitudinal study.

Background: Gait acquisition is supported by changes in the neuromusculoskeletal system of the child. Changes in the dimensions of the body structures resulting from the growth of the child partly explain gait improvement in the first year of life.

Objectives: To evaluate whether changes in body mass and leg length modulate the effect of independent gait practice (experience) on gait speed and stride length.

How do children and caregivers perceive their experience of undergoing the CIMT protocol?

Objective: Constraint-induced movement therapy (CIMT) is an effective intervention to improve hand function in children with cerebral palsy (CP). However, some of its features, including the restraining of the unaffected arm and the intensive training, may result in stressful experiences for children and interfere with family routine. This study aimed to document the perceptions of children with CP and their caregivers regarding the experience of undergoing the CIMT protocol.

Beliefs about the use of baby walkers.

Objectives: To understand the opinion of the parents about the baby walker and compare the age of gait acquisition between infants that used a walker and those that did not.

Methods: In this quali-quantitative study, an interview involving a semi-structured questionnaire was carried out with 26 parents, 14 of whose infants used the equipment (BWG) and 12 of whose infants did not (NBWG) prior to gait acquisition. After extensive content analysis, categories for interpreting the results emerged.

Influences of the extensor portion of the gluteus maximus muscle on pelvic tilt before and after the performance of a fatigue protocol.

Introduction: There is a lack of data in the literature for determining the influences of the extensor portion of the gluteus maximus muscle on pelvic tilting and, thus, on lumbar stability.

Objectives: To assess the influences of the extensor portion of the gluteus maximus muscle on pelvic tilt.

Methods: Ten healthy young subjects were recruited, with a body mass index (BMI) below 24.

Evaluation of respiratory mechanics and lung histology in a model of atelectasis.

To develop a reproducible model of atelectasis, 15 mechanically ventilated Wistar rats were wrapped around the thorax/abdomen with a sphygmomanometer. The cuff was inflated to transpulmonary pressures (PL) of -4 cmH2O (group A) and -8 cmH2O (group B) for 5 sec. Group C was not compressed.
