Parent-child interaction after home-visiting intervention for children born extremely preterm-A randomised clinical trial.

Aim: To determine whether a strength-based home-visiting program enhances parent-child interaction during the first year at home for children born extremely preterm (gestational age < 28).

Methods: A randomised controlled trial of 130 infants born extremely preterm 2018-2021 in Stockholm, allocated to either the Stockholm preterm interaction-based intervention (SPIBI) (n = 66) or an extended follow-up program (n = 64). The intervention group received ten home visits during the first year by a trained interventionist following SPIBI guidelines: an interaction-based intervention supporting sensitive parental responses to infants' signals.

Signs of perceptual disorder during movement were reliably assessed in children with cerebral palsy in Sweden.

Aim: The aim of this Swedish study was to evaluate the assessment of clinical signs of perceptual disorder in children with cerebral palsy (CP).

Methods: Three experienced raters assessed 56 videos of 19 children from 1 to 18 years of age with bilateral spastic CP, which were recorded by colleagues at an Italian hospital. Six signs were evaluated for inter-rater reliability and criterion validity.

Changes in prevalence of non-optimal neurological condition between 6.5 and 12 years in children born extremely preterm.

Aim: To assess prevalence of non-optimal neurological condition and associations with motor function in children born extremely preterm (EPT) up to early adolescence, and to examine potential changes in neurological condition between 6.5 and 12 years.

Method: A prospective cohort of one hundred six children (EPT n = 62, term n = 44) was assessed at 6.

Mobile Solutions for Clinical Surveillance and Evaluation in Infancy-General Movement Apps.

The Prechtl General Movements Assessment (GMA) has become a clinician and researcher toolbox for evaluating neurodevelopment in early infancy. Given that it involves the observation of infant movements from video recordings, utilising smartphone applications to obtain these recordings seems like the natural progression for the field. In this review, we look back on the development of apps for acquiring general movement videos, describe the application and research studies of available apps, and discuss future directions of mobile solutions and their usability in research and clinical practice.

Discrete white matter abnormalities at age 8-11 years in children born extremely preterm are not associated with adverse cognitive or motor outcomes.

Aim: Little is known about the prevalence of discrete white matter abnormalities (WMA) beyond the first years in children born extremely preterm (EPT) and the relation to neurodevelopmental outcomes. Our aim was to investigate the prevalence of discrete WMA in children born EPT and the relationship to neonatal white matter injuries (WMI), white matter (WM) volume, WM diffusivity and neurodevelopment.

Methods: The study was a part of a longitudinal follow-up study of EPT neonates.

Usability and inter-rater reliability of the NeuroMotion app: A tool in General Movements Assessments.

Background: Early intervention after perinatal brain insults requires early detection of infants with cerebral palsy (CP). General Movements Assessments (GMA) in the fidgety movement period has a high predictive value for CP.

Aim: To investigate the NeuroMotion™ app's usability regarding film quality and user experience and to assess the inter-rater reliability of GMA in a neonatal risk group.

Early prediction of neurodevelopmental outcomes at 12 years in children born extremely preterm.

Background: Extremely preterm (EPT) birth is a major risk factor for neurodevelopmental impairments. The aim was to evaluate the predictive value of Prechtl General Movement Assessment (GMA), including the Motor Optimality Score-Revised (MOS-R), at 3 months corrected age (CA) for adverse neurodevelopmental outcome at the age of 12 years.

Methods: The GMA, including the MOS-R, was applied at 3 months CA and outcomes were assessed at 12 years by Touwen's neurological examination, the Movement Assessment Battery for Children-2, and chart reviews.

Movements and posture in infants born extremely preterm in comparison to term-born controls.

Background: Identifying altered motor development at an early stage is crucial for infants born extremely preterm (EPT), as they face a high risk of long-term neurodevelopmental impairment. The Prechtl General Movement Assessment (GMA), including the Motor Optimality Score Revised (MOS-R), can provide important insights into these infants' later neurodevelopmental function.

Aims: To compare age-specific movements and postures in infants born EPT compared to term-born controls at three months corrected age.

Psychometric properties of the Knee injury and Osteoarthritis Outcome Score for Children (KOOS-Child) in children with knee disorders.

Background: The Knee injury and Osteoarthritis Outcome Score (KOOS) is a self-administered valid and reliable questionnaire for adults with joint injury or degenerative disease. Recent data indicate a lack of comprehensibility when this is used with children. Thus, a preliminary KOOS-Child was developed.

Development of the Knee Injury and Osteoarthritis Outcome Score for children (KOOS-Child): comprehensibility and content validity.

Background And Purpose: The Knee Injury and Osteoarthritis Outcome Score (KOOS) is distinguished from other knee-specific measures by the inclusion of separate scales for evaluation of activities of daily living, sports and recreation function, and knee-related quality of life, with presentation of separate subscale scores as a profile. However, its applicability in children has not been established. In this study, we examined how well the KOOS could be understood in a cohort of children with knee injury, with a view to preparing a pediatric version (KOOS-Child).

Reliability and reference values of two clinical measurements of dynamic and static knee position in healthy children.

Purpose: The purposes of this study were to evaluate reliability of the Single-limb mini squat test (a dynamic measure of medio-lateral knee position) and the Quadriceps-angle (Q-angle) (a static measure of medio-lateral knee position), present paediatric reference values of the Q-angle, and evaluate the association between the tests.

Methods: Two hundred and forty-six healthy children (9-16 years) were included (intra/inter-rater reliability for Q-angle (n = 37/85) and for Single-limb mini squat test (n = 33/28)). Dynamic medio-lateral knee position was assessed by the Single-limb mini squat test.

Reliability of a new instrument for measuring plantarflexor muscle strength.

Objectives: To test the reliability of a new muscle strength testing instrument (the Strength Measuring Chair [SMC]) designed to quantify isometric strength in the lower extremities, and to determine the agreement between the SMC and an isokinetic dynamometer (Biodex).

Design: Isometric strength tests were performed in plantarflexors with 2 different knee positions (60 degrees, 30 degrees). Measurements were taken at 3 different sessions.

Trunk and center of mass movements during gait in children with juvenile idiopathic arthritis.

Motion of the body center of mass (CoM) can often indicate the overall effect of the strategy of forward progression used. In the present study, focus is placed on trunk movements in the sagittal, coronal, and transverse/rotation plane, as well as placement of the CoM, during gait in children with juvenile idiopathic arthritis (JIA). Seventeen children with JIA, all with polyarticular lower extremity involvement were examined before and approximately two weeks after treatment with intra-articular cortico-steroid injections.
