GAME (Goals - Activity - Motor Enrichment): protocol of a single blind randomised controlled trial of motor training, parent education and environmental enrichment for infants at high risk of cerebral palsy

Parent-Guided Developmental Intervention for Infants With Very Low Birth Weight: A Randomized Clinical Trial

Importance

Early interventions improve neurodevelopmental outcomes after preterm birth, but few studies of early intervention have focused on preterm infants whose families reside in low- or middle-income countries (LMICs).

Objective

To evaluate whether parent-guided early intervention improves the neurodevelopmental outcomes of preterm infants in an LMIC.

Design, Setting, and Participants

This randomized clinical trial was performed at a high-risk obstetric referral hospital in Brazil, with outcome evaluations by examiners masked to randomization group. Eligibility criteria were (1) birth at the study hospital, (2) residence within 40 km of the birth hospital, and (3) gestational age of less than 32 weeks or birth weight of less than 1500 g. Of 138 enrolled infants, 19 died after randomization and 19 withdrew from the study; all other enrollees (50 per randomization group) were evaluated for the primary outcome. Data were collected from January 1, 2016, to May 31, 2022, and analyzed from June 10 to July 31, 2022.

Interventions

On postnatal day 7, infants were randomized to usual care, consisting of support for lactation, kangaroo care, and routine developmental therapies, or to a parent-guided enhanced developmental intervention, consisting of usual care plus infant massage and enhanced visual stimulation, auditory stimulation, social interactions, and support for motor development, instructed by developmental therapists.

Main Outcomes and Measures

The primary outcome was the Bayley Scales of Infant and Toddler Development-Third Edition score at 18 months of age adjusted for prematurity.

Results

Among the 100 infants included in the analysis, mean (SD) gestational age was 28.4 (2.2) weeks, and 57 (57%) were male. The mean (SD) gestational age for the intervention group was 28.3 (2.3) weeks; for the usual care group, 28.5 (2.2) weeks. Female infants accounted for 21 infants (42%) of the intervention group and 22 (44%) of the usual care group; male infants, 29 (58%) and 28 (56%), respectively. The enhanced developmental intervention group had higher cognitive scores at 18 months of corrected age (mean [SD], 101.8 [11.9] vs 97.3 [13.5]; mean difference, 4.5 [95% CI, 0.1-8.9]).

Conclusions and Relevance

In this randomized clinical trial of a parent-guided developmental intervention for early cognitive function of very preterm or very low birth weight infants implemented in an LMIC, the intervention improved very preterm infants' neurodevelopmental outcomes at 18 months of adjusted age. Parent-guided early intervention can improve neurodevelopmental outcome of very preterm infants born in LMICs.

Early Detection and Intervention for Children with High Risk of Cerebral Palsy: A Survey of Physical Therapists and Occupational Therapists in Brazil

AIMS

The purpose of this study was to assess the current clinical practice of physiotherapists and occupational therapists on early detection and early intervention for children with cerebral palsy (CP) in Brazil.

METHODS

This was a cross-sectional study. A purpose-developed electronic survey was disseminated across the country to physiotherapists and occupational therapists working with young children with or at risk of CP.

RESULTS

A total of 205 anonymous respondents were included. Most participants (64.4%) agree that the diagnosis of CP can be made before 6 months of age. General Movements Assessment (26.8%) and Hammersmith Infant Neurological Examination (37.1%) were used infrequently. Infants at risk for CP receive therapy twice a week or more by 58.5% of therapists, 93.2% identified parents' goals as the most important factor in customizing the early intervention program. The most frequent intervention strategies for this age group were active stimulation of the child (n = 182), family training (n = 161), strategies to optimize the environment (n = 143), and neurodevelopmental treatment/Bobath (n = 99).

CONCLUSIONS

Currently, pediatric physiotherapists and occupational therapists in Brazil do not fully incorporate best practice tools for early identification of children with CP, nor sufficient best evidence-based interventions.

Assessing engagement in rehabilitation: development, validity, reliability, and responsiveness to change of the Rehabilitation Observation Measure of Engagement (ROME)

PURPOSE

We describe the development of an observational video coding tool, the Rehabilitation Observation Measure of Engagement (ROME), to quantify engagement in rehabilitative settings at the person (internal state of an individual) and between-system (interaction between individuals) level.

METHODS

Forty-nine children with unilateral spastic cerebral palsy (29 males; Age: M = 9.28 yrs, SD = 3.08 yrs) and their interventionists were videotaped during different activities. Construct validity was examined by correlating the ROME with the Engagement vs. Disaffection with Learning Survey and the Pediatric Rehabilitation Intervention Measure of Engagement - Observation questionnaire. Inter- and intra-rater reliability were examined using two independent raters. The ROME's responsiveness to change was examined by comparing scores across activities.

RESULTS

For construct validity, results showed a positive correlation for person-level engagement (r = 0.444, p = 0.003). No relationship was found between-system-level engagement. High intrarater (91.8%) and interrater (96.1%) reliability was found. The ROME's responsiveness to change was supported by children exhibiting lower engagement scores during repetitive shaping activities.

CONCLUSION

These findings provide evidence that the ROME is a reliable tool to objectively examine the construct of engagement within rehabilitation and is valid for quantifying person-level engagement. It provides information that cannot be extracted from questionnaires and can help guide intervention decisions.

Efficacy of Early Intervention for Infants With Cerebral Palsy in an LMIC: An RCT

OBJECTIVE

To test efficacy of a parent-delivered multidomain early intervention (Learning through Everyday Activities with Parents [LEAP-CP]) for infants with cerebral palsy (CP) compared with equal-dose of health advice (HA), on (1) infant development; and (2) caregiver mental health. It was hypothesized that infants receiving LEAP-CP would have better motor function, and caregivers better mental health.

METHODS

This was a multisite single-blind randomized control trial of infants aged 12 to 40 weeks corrected age (CA) at risk for CP (General Movements or Hammersmith Infant Neurologic Examination). Both LEAP-CP and HA groups received 15 fortnightly home-visits by a peer trainer. LEAP-CP is a multidomain active goal-directed intervention. HA is based on Key Family Practices, World Health Organization. Primary outcomes: (1) infants at 18 months CA: Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT mobility); and (2) caregiver: Depression Anxiety and Stress Scale.

RESULTS

Of eligible infants, 153 of 165 (92.7%) were recruited (86 males, mean age 7.1±2.7 months CA, Gross Motor Function Classification System at 18 m CA: I = 12, II = 25, III = 9, IV = 18, V = 32). Final data were available for 118 (77.1%). Primary (PEDI-CAT mobility mean difference = 0.8 (95% CI -1.9 to 3.6) P = .54) and secondary outcomes were similar between-groups. Modified-Intention-To-Treat analysis on n = 96 infants with confirmed CP showed Gross Motor Function Classification System I and IIs allocated to LEAP-CP had significantly better scores on PEDI-CAT mobility domain (mean difference 4.0 (95% CI = 1.4 to 6.5), P = .003) compared with HA.

CONCLUSIONS

Although there was no overall effect of LEAP-CP compared with dose-matched HA, LEAP-CP lead to superior improvements in motor skills in ambulant children with CP, consistent with what is known about targeted goal-directed training.

Factors influencing caregiver buy-in to early intervention physical therapy

OBJECTIVE

The family-centered care framework of Early Intervention (EI) has shifted the focus toward caregiver engagement, but the underlying processes that build this are unknown. The aims of this study were 1) to describe the process of caregiver engagement in therapy and (2) to identify factors perceived to influence caregiver buy-in, confidence, and engagement in EI.

METHODS

This preliminary descriptive study utilized quantitative questionnaires and qualitative semi-structured interviews of EI participants (23 caregivers and four physical therapists). Interviews were transcribed and theme coded until saturation was achieved and a concept map was developed.

RESULTS

All caregivers believed that their children benefited from EI, that they were empowered and confident in caring for their children, and their quality of life improved based on the quantitative data. The qualitative data revealed that building a rapport and therapeutic relationship is the foundation to developing buy-in. Reciprocal communication is critical to the relationship and the buy-in. Caregiver knowledge and awareness of progress foster caregiver buy-in and confidence once the relationship is established.

CONCLUSION

Improved understanding of the factors influencing the development of buy-in will provide a framework for the clinician to enhance caregiver buy-in. Enhanced buy-in may promote parental engagement and improved outcomes for the child and family.

Cerebral Palsy - Early Diagnosis and Intervention Trial: protocol for the prospective multicentre CP-EDIT study with focus on diagnosis, prognostic factors, and intervention

BACKGROUND

Early diagnosis of cerebral palsy (CP) is important to enable intervention at a time when neuroplasticity is at its highest. Current mean age at diagnosis is 13 months in Denmark. Recent research has documented that an early-diagnosis set-up can lower diagnostic age in high-risk infants. The aim of the current study is to lower diagnostic age of CP regardless of neonatal risk factors. Additionally, we want to investigate if an early intervention program added to standard care is superior to standard care alone.

METHODS

The current multicentre study CP-EDIT (Early Diagnosis and Intervention Trial) with the GO-PLAY intervention included (Goal Oriented ParentaL supported home ActivitY program), aims at testing the feasibility of an early diagnosis set-up and the GO-PLAY early intervention. CP-EDIT is a prospective cohort study, consecutively assessing approximately 500 infants at risk of CP. We will systematically collect data at inclusion (age 3-11 months) and follow a subset of participants (n = 300) with CP or at high risk of CP until the age of two years. The GO-PLAY early intervention will be tested in 80 infants with CP or high risk of CP. Focus is on eight areas related to implementation and perspectives of the families: early cerebral magnetic resonance imaging (MRI), early genetic testing, implementation of the General Movements Assessment method, analysis of the GO-PLAY early intervention, parental perspective of early intervention and early diagnosis, early prediction of CP, and comparative analysis of the Hand Assessment for Infants, Hammersmith Infant Neurological Examination, MRI, and the General Movements method.

DISCUSSION

Early screening for CP is increasingly possible and an interim diagnosis of "high risk of CP" is recommended but not currently used in clinical care in Denmark. Additionally, there is a need to accelerate identification in mild or ambiguous cases to facilitate appropriate therapy early. Most studies on early diagnosis focus on identifying CP in infants below five months corrected age. Little is known about early diagnosis in the 50% of all CP cases that are discernible later in infancy. The current study aims at improving care of patients with CP even before they have an established diagnosis.

TRIAL REGISTRATION

ClinicalTrials.gov ID 22013292 (reg. date 31/MAR/2023) for the CP-EDIT cohort and ID 22041835 (reg. date 31/MAR/2023) for the GO-PLAY trial.

Protocol for a randomized controlled trial to evaluate a year-long (NICU-to-home) evidence-based, high dose physical therapy intervention in infants at risk of neuromotor delay

INTRODUCTION

Developmental disabilities and neuromotor delay adversely affect long-term neuromuscular function and quality of life. Current evidence suggests that early therapeutic intervention reduces the severity of motor delay by harnessing neuroplastic potential during infancy. To date, most early therapeutic intervention trials are of limited duration and do not begin soon after birth and thus do not take full advantage of early neuroplasticity. The Corbett Ryan-Northwestern-Shirley Ryan AbilityLab-Lurie Children's Infant Early Detection, Intervention and Prevention Project (Project Corbett Ryan) is a multi-site longitudinal randomized controlled trial to evaluate the efficacy of an evidence-based physical therapy intervention initiated in the neonatal intensive care unit (NICU) and continuing to 12 months of age (corrected when applicable). The study integrates five key principles: active learning, environmental enrichment, caregiver engagement, a strengths-based approach, and high dosage (ClinicalTrials.gov identifier NCT05568264).

METHODS

We will recruit 192 infants at risk for neuromotor delay who were admitted to the NICU. Infants will be randomized to either a standard-of-care group or an intervention group; infants in both groups will have access to standard-of-care services. The intervention is initiated in the NICU and continues in the infant's home until 12 months of age. Participants will receive twice-weekly physical therapy sessions and caregiver-guided daily activities, assigned by the therapist, targeting collaboratively identified goals. We will use various standardized clinical assessments (General Movement Assessment; Bayley Scales of Infant and Toddler Development, 4th Edition (Bayley-4); Test of Infant Motor Performance; Pediatric Quality of Life Inventory Family Impact Module; Alberta Infant Motor Scale; Neurological, Sensory, Motor, Developmental Assessment; Hammersmith Infant Neurological Examination) as well as novel technology-based tools (wearable sensors, video-based pose estimation) to evaluate neuromotor status and development throughout the course of the study. The primary outcome is the Bayley-4 motor score at 12 months; we will compare scores in infants receiving the intervention vs. standard-of-care therapy.

Embedding Play to Enrich Physical Therapy

Play is an active process by which an individual is intrinsically motivated to explore the self, the environment, and/or interactions with another person. For infants and toddlers, engaging in play is essential to support development across multiple domains. Infants and toddlers with or at risk of motor delays may demonstrate differences in play or challenges with engaging in play activities compared to typically developing peers. Pediatric physical therapists often use play as a modality to engage children in therapeutic assessment and interventions. Careful consideration of the design and use of physical therapy that embeds play is needed. Following a 3-day consensus conference and review of the literature, we propose physical therapy that embeds play should consider three components; the child, the environment, and the family. First, engage the child by respecting the child's behavioral state and following the child's lead during play, respect the child's autonomous play initiatives and engagements, use activities across developmental domains, and adapt to the individual child's needs. Second, structure the environment including the toy selection to support using independent movements as a means to engage in play. Allow the child to initiate and sustain play activities. Third, engage families in play by respecting individual family cultures related to play, while also providing information on the value of play as a tool for learning. Partner with families to design an individualized physical therapy routine that scaffolds or advances play using newly emerging motor skills.

Study protocol: peer delivered early intervention (Learning through Everyday Activities with Parents for Infants at risk of Cerebral Palsy: LEAP-CP) for First Nation Australian infants at high risk of cerebral palsy - an RCT study

INTRODUCTION

Cerebral palsy (CP) is the most common childhood physical disability with rates approximately 50% higher in First Nations Australian children. This study aims to evaluate a culturally-adapted parent-delivered early intervention programme for First Nations Australian infants at high risk of CP (Learning through Everyday Activities with Parents for infants with CP; LEAP-CP).

METHODS AND ANALYSIS

This study is a randomised assessor masked controlled trial. Infants with birth/postnatal risk factors will be eligible for screening. Infants at high risk of CP ('absent fidgety' on General Movements Assessment, and/or 'suboptimal score' on the Hammersmith Infant Neurological Examination) aged 12-52 weeks corrected age will be recruited. Infants and their caregivers will be randomised to receive LEAP-CP (intervention) or health advice (comparator). LEAP-CP is a culturally-adapted programme of 30 home visits delivered by a peer trainer (First Nations Community Health Worker); and includes goal-directed active motor/cognitive strategies, CP learning games and caregiver educational modules. The control arm receives a monthly health advice visit, based on the Key Family Practices, WHO. All infants continue to receive standard (mainstream) Care as Usual. Dual child primary outcomes are Peabody Developmental Motor Scales-2 (PDMS-2) and Bayley Scales of Infant Development-III. The primary caregiver outcome is the Depression, Anxiety and Stress Scale. Secondary outcomes include function, goal attainment, vision, nutritional status and emotional availability.

SAMPLE SIZE

total of 86 children (43/group) will enable an effect size of 0.65 on the PDMS-2 to be detected (80% power, α=0.05; 10% attrition).

ETHICS AND DISSEMINATION

Ethics approval through Queensland ethics committees and Aboriginal Controlled Community Health Organisation Research Governance Groups, with families providing written informed consent. Findings will be disseminated with guidance from the Participatory Action Research, in collaboration with First Nations communities; peer-reviewed journal publications and national/international conference presentations.

Harnessing neuroplasticity to improve motor performance in infants with cerebral palsy: a study protocol for the GAME randomised controlled trial

INTRODUCTION

Cerebral palsy (CP) is the most common physical disability of childhood worldwide. Historically the diagnosis was made between 12 and 24 months, meaning data about effective early interventions to improve motor outcomes are scant. In high-income countries, two in three children will walk. This evaluator-blinded randomised controlled trial will investigate the efficacy of an early and sustained Goals-Activity-Motor Enrichment approach to improve motor and cognitive skills in infants with suspected or confirmed CP.

METHODS AND ANALYSIS

Participants will be recruited from neonatal intensive care units and the community in Australia across four states. To be eligible for inclusion infants will be aged 3-6.5 months corrected for prematurity and have a diagnosis of CP or 'high risk of CP' according to the International Clinical Practice Guideline criteria. Eligible participants whose caregivers consent will be randomly allocated to receive usual care or weekly sessions at home from a GAME-trained study physiotherapist or occupational therapist, paired with a daily home programme, until age 2. The study requires 150 participants per group to detect a 0.5 SD difference in motor skills at 2 years of age, measured by the Peabody Developmental Motor Scales-2. Secondary outcomes include gross motor function, cognition, functional independence, social-emotional development and quality of life. A within-trial economic evaluation is also planned.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Sydney Children's Hospital Network Human Ethics Committee in April 2017 (ref number HREC/17/SCHN/37). Outcomes will be disseminated through peer-reviewed journal publications, presentations at international conferences and consumer websites.

andomised to early neuroprotection and neurorehabilitation: protocol for a follow-up study of participants from four randomised clinical trials

INTRODUCTION

School readiness includes cognitive, socio-emotional, language and physical growth and development domains which share strong associations with life-course opportunities. Children with cerebral palsy (CP) are at increased risk of poor school readiness compared with their typically developing peers. Recently, earlier diagnosis of CP has allowed interventions to commence sooner, harnessing neuroplasticity. First, we hypothesise that early referral to intervention for children at-risk of CP will lead to improved school readiness at 4-6 years relative to placebo or care as usual. Second, we hypothesise that receipt of early diagnosis and early intervention will lead to cost-savings in the form of reduced healthcare utilisation.

METHODS AND ANALYSIS

Infants identified as at-risk of CP ≤6 months corrected age (n=425) recruited to four randomised trials of neuroprotectants (n=1), early neurorehabilitation (n=2) or early parenting support (n=1) will be re-recruited to one overarching follow-up study at age 4-6 years 3 months. A comprehensive battery of standardised assessments and questionnaires will be administered to assess all domains of school readiness and associated risk factors. Participants will be compared with a historical control group of children (n=245) who were diagnosed with CP in their second year of life. Mixed-effects regression models will be used to compare school readiness outcomes between those referred for early intervention versus placebo/care-as-usual. We will also compare health-resource use associated with early diagnosis and intervention versus later diagnosis and intervention.

ETHICS AND DISSEMINATION

The Children's Health Queensland Hospital and Health Service, The University of Queensland, University of Sydney, Monash University and Curtin University Human Research Ethics Committees have approved this study. Informed consent will be sought from the parent or legal guardian of every child invited to participate. Results will be disseminated in peer-reviewed journals, scientific conferences and professional organisations, and to people with lived experience of CP and their families.

"A Different Ride": A Qualitative Interview Study of Parents' Experience with Early Diagnosis and Goals, Activity, Motor Enrichment (GAME) Intervention for Infants with Cerebral Palsy

Cerebral palsy is the most common physical disability of childhood, and early diagnosis followed by best practice early intervention is important for optimizing child and family outcomes. We investigated parents' views of an early diagnosis of cerebral palsy (CP), followed by Goals, Activity, Motor Enrichment (GAME) intervention. Semi-structured interviews were conducted within a pilot randomised clinical trial. Transcriptions were analyzed using grounded theory. Participants were nine mothers whose infants had received GAME intervention because they were identified as being at high risk for cerebral palsy early in infancy. The parenting experience was described as a "different ride". The diagnosis was devastating with many time-consuming challenges, but acceptance ensued. Parents wanted an early diagnosis, prognosis, and early intervention, despite the anxiety and workload, because it meant they could help. Parents perceived that GAME was beneficial because they were taught how to help; it was goal-based and home-based. They believed the collaboration and communication skills of the therapist shaped success. Future research should focus on a broader range of participants to understand parent's experiences with key aspects of early intervention more fully.

Early Intervention Involving Specific Task-Environment-Participation (STEP) Protocol for Infants at Risk: A Feasibility Study

Aims: To verify the feasibility and preliminary effects of the STEP protocol, an intervention based on specific motor skills, environmental factors and participation, in infants at biological risk.Methods: Twenty-eight at-risk infants (STEP Protocol = 14; Standard Intervention = 14), aged 3-9 months and at risk for developmental delay. The following outcomes were assessed: motor skills (Alberta Infant Motor Scale-AIMS); frequency and involvement of participation (Young Children's Participation and Environment Measure-YC-PEM), and home environment opportunities (Affordances in the Home Environment for Motor Development-AHEMD-IS). For both groups, interventions were provided by parents. The intervention for group was based on the following principles: (1) standard intervention: stimulation of motor skills; (2) STEP: stimulation of motor skills, participation, mother-infant interaction, environmental enrichment. A mean comparison test was applied to verify difference between groups after the intervention.Results: The protocol showed good retention and recruitment rates. The STEP group had significantly higher outcomes after intervention on the AIMS (p = 0.014); frequency (p = 0.02) and engagement (p = 0.03) in participation, when compared to standard intervention.Conclusions: The results showed that the STEP protocol is feasible, and presents better results compared to the standard intervention, which reinforces the importance of promoting participation, specific motor skills and family involvement.

Parental engagement in early intervention for infants with cerebral palsy-A realist synthesis

BACKGROUND

Emphasis on parental engagement strategies within occupational therapy and physiotherapy early intervention (EI) programmes for infants at high risk of cerebral palsy (CP) has increased. This reflects consensus that increasing parent participation enhances treatment efficacy, potentially improving infant and parent outcomes. However, evaluation of parental engagement in EI is complex. Despite the growing application of parental engagement strategies, aligned with family-centred care practice, theoretical evaluation is currently lacking within the literature. This realist synthesis aimed to identify component theories underlying EI strategies to support parental engagement and to use empirical findings to evaluate how these work in practice.

METHODS

Realist synthesis: Databases Medline, Embase, Amed, CINAHL and PsychInfo were searched (from February 1985 - February 2020); further articles were sourced from reference lists. A data extraction form was used, and a Critical Appraisal Skills Programme tool was used to assess study rigour.

RESULTS

Twenty-six articles were included. Quality of relationships, parent education and intervention co-design were the key themes related to parental engagement strategies. Findings indicate that constructive parent reasoning mechanisms of trust, belief, sense of control, perceived feasibility of home programme delivery and ultimately motivation are linked to the underlying intervention resources afforded by specific strategies (e.g., coaching pedagogy). These responses are precursors to engagement outcomes that include increased parental self-efficacy and adherence. Importantly, parental self-efficacy can initiate a process of change leading to improved parental confidence and anxiety.

CONCLUSIONS

Sensitively designed programme strategies, centred on relational quality between parent, infant and therapist, are fundamental for effective parent connection, involvement and investment within EI for infants with CP.

The SIT-PT Trial Protocol: A Dose-Matched Randomized Clinical Trial Comparing 2 Physical Therapist Interventions for Infants and Toddlers With Cerebral Palsy

OBJECTIVE

Although early intervention for infants at risk for cerebral palsy is routinely recommended, the content of intervention is poorly described, varies widely, and has mixed supporting evidence. The purpose of this study was to compare efficacy of 2 interventions grounded in differing domains of the International Classification of Functioning, Disability and Health on developmental outcomes of infants with or at high risk of cerebral palsy.

METHODS

Infants who meet inclusion criteria will be randomized into either Sitting Together and Reaching To Play or Movement, Orientation, Repetition, Exercise Physical Therapy groups. Both groups will receive intervention twice weekly for 3 months and follow-up at 3, 6, 9, and 12 months from baseline. The primary objectives compare changes over time and between groups in sitting, gross motor, and cognitive development. The setting is the infant's home unless the caregiver requests otherwise. One hundred and fifty infants between 8 and 24 months of age will be enrolled in 3 geographically, racially, and ethnically diverse sites: Los Angeles, California; Omaha, Nebraska; and Seattle, Washington. Enrolled infants will demonstrate motor delays, emerging sitting skills, and signs of neurologic impairment. Sitting Together and Reaching To Play targets activities including sitting, reaching, and motor-based problem solving to improve global development. In contrast, Movement, Orientation, Repetition, Exercise Physical Therapy focuses on strengthening and musculoskeletal alignment while encouraging repeated movement practice. Outcome measures include the Gross Motor Function Measure, Bayley Scales of Infant Development-IV, Assessment of Problem Solving in Play, and a Parent Child Interaction assessment. Enrolled children will maintain usual intervention services due to ethical concerns with intervention withdrawal.

IMPACT

This will be the first study, to our knowledge, comparing efficacy of early physical therapy with dose-matched interventions and well-defined key principles. The outcomes will inform selection of key principle of intervention in this population.

Investigation of the effectiveness of family collaborative physiotherapy programs applied to high-risk infants

BACKGROUND

The inclusion of families in intervention programs for infants may be more effective in ensuring adherence and positive outcomes. Approaches that include natural and enriched environments that provide communication and family interaction are important in the rehabilitation of high-risk infants.

OBJECTIVE

To compare the effectiveness of Family Collaborative Approach (FCA) and Neurodevelopmental Therapy (NDT)-based family training.

METHODS

High-risk infants (n = 63) with a mean age of 32.60 ± 4.53 months received early intervention for 12 weeks. Prechtl's General movements (GMs) assessment, Hammersmith Neonatal Neurological Examination (HNNE), Hammersmith Infant Neurological Examination (HINE), BAYLEY-III Scales of Infant and Toddler Development, and Third Addition (BSID-III) were performed.

RESULTS

Significant differences between groups were found in HINE scores at the 3rd, 6th, and 12th months (p ≤ .028), and in BSID-III scores at the 6th month (cognitive, language, and motor) (p < .001) and the 12th month (language) (p = .031). There was significant difference between NDT and control group in 3rd month HINE scores and Reflex&Reactions scores (p ≤ .021). FCA group and NDT group was significantly different from control group in 6th month HINE (p = .032) and 12th month HINE scores (p = .007). FCA group significantly different from NDT group (p ≤ .002) and control group (p < .001) in 6th month BSID-III cognitive, language, and motor scores. There was significant difference between FCA and control group in 12 month BSID-III language scores (p = .024).

CONCLUSIONS

Early physiotherapy interventions were effective in high-risk infants and FCA program was superior to NDT.

Effect of Contingency Paradigm-Based Interventions on Developmental Outcomes in Young Infants: A Systematic Review

PURPOSE

The purpose of this systematic review was to identify controlled trials evaluating the efficacy of contingency paradigm-based interventions to improve feeding, motor, or cognitive outcomes during the first year of life.

SUMMARY OF KEY POINTS

Seventeen studies, including 10 randomized controlled trials, incorporating contingency paradigm-based interventions were identified. Three of 3 trials reported improvements in nutritive sucking using pacifier-activated lullaby in preterm infants before term age. Seven of 12 trials reported improvements in reaching, manual exploration, and kicking behaviors in term and preterm infants; and 6 of 10 trials reported gains in early cognition using sticky mittens and contingent toys.

CONCLUSION AND RECOMMENDATIONS FOR CLINICAL PRACTICE

Contingency paradigm-based interventions can improve feeding outcomes in the neonatal intensive care unit in very preterm infants, and increase reaching, and perceptual-cognitive behaviors in term infants. Future research is needed to establish contingency paradigms as an effective early intervention strategy.

WHAT THIS ADDS TO THE EVIDENCE

This review synthesizes a body of literature on contingency paradigm-based interventions and highlights its potential paradigm-based interventions to improve developmental outcomes in infants.

From Hemispheric Asymmetry through Sensorimotor Experiences to Cognitive Outcomes in Children with Cerebral Palsy

Recent neuroimaging studies allowed us to explore abnormal brain structures and interhemispheric connectivity in children with cerebral palsy (CP). Behavioral researchers have long reported that children with CP exhibit suboptimal performance in different cognitive domains (e.g., receptive and expressive language skills, reading, mental imagery, spatial processing, subitizing, math, and executive functions). However, there has been very limited cross-domain research involving these two areas of scientific inquiry. To stimulate such research, this perspective paper proposes some possible neurological mechanisms involved in the cognitive delays and impairments in children with CP. Additionally, the paper examines the ways motor and sensorimotor experience during the development of these neural substrates could enable more optimal development for children with CP. Understanding these developmental mechanisms could guide more effective interventions to promote the development of both sensorimotor and cognitive skills in children with CP.

Tele-care intervention performed by parents involving specific task- environment- participation (STEP protocol) for infants at risk for developmental delay: protocol of randomized controlled clinical trial

BACKGROUND

With the implementation of social distancing due to the Covid-19 pandemic, many at-risk infants are without therapy. An alternative mode of therapy in this situation is tele-care, a therapy in which assessments and interventions are carried out online, in the home environment. We describe a tele-care protocol involving parent delivered task and context specific movement training, participation and environmental adaptation for infants at risk for developmental delay.

METHODS

Randomized controlled trial. Infants at risk, with 3 to 9 months corrected age, will be included, and randomized into two groups: control group (conventional guidelines) and experimental group (task, environment and participation in context-specific home program). Infants will be assessed for motor capacity (Infant Motor Profile and Alberta Infant Motor Scale); participation (Young Children's Participation and Environment Measure) and environment factors (Parent-Child Early Relational Assessment; Affordances in the Home Environment for Motor Development). The intervention period will be 10 weeks, and evaluations will be carried out before and after that period. All the assessment and intervention procedures will be carried out online, with instructions to parents for home therapy. The statistical analysis will be guided according to the distribution of the data, and a significance level of 5% will be adopted. All ethical approvals were obtained by the Ethics Committee of the University of São Carlos (Case number 31256620.5.0000.5504). The protocol will follow the SPIRIT statement. Findings will be disseminated in peer-reviewed publications and presented at national and international conferences.

DISCUSSION

The results of this study will describe the effectiveness of a home intervention, focusing on specific activities, participation and environmental changes. These results will support the implementation of a remote protocol, with lower financial costs and focused on the particularities of the family. This type of care model can possibly help public policies to ensure equal access to evidence-based quality healthcare.

Leg Movement Rate before and after a Caregiver-Provided Intervention for Infants at Risk of Developmental Disability: A Pilot Study

AIM

Our purpose was to assess daily leg movement rate before and after a caregiver-provided in-home intervention for infants at risk for developmental disability. We also assessed adherence and quality of caregiver-child interaction.

METHODS

Twelve infants, at risk for developmental disabilities, and their caregivers participated in an intervention focused on increasing leg movements. Intervention started between 3- and 6-months corrected age and ended once the infant was able to sit independently or at 9 months corrected age, whichever occurred first. Infants were assessed monthly.

RESULTS

Infants at risk for developmental disabilities who were moving less than 1200 leg movements per hour awake at the start of the intervention increased their daily leg movement rate following the intervention (Median [range]: pre-1047 [506-1056], post- 1104 [655-1359], p = 0.040). Additionally, the caregivers had a high adherence (Median: 89%, Range: 11.43%-329.17%) and good quality of caregiver-child interaction (Median NCAST total: 46, Range: 34-59); and maintained similar amounts of adherence (p = 0.575) and quality of caregiver-child interaction (p = 0.432) throughout the intervention.

CONCLUSION

This study provides preliminary evidence that leg movement rate has the potential to be used as an outcome measure to assess an infant's progress and motor practice during an intervention.

Early clinical and MRI biomarkers of cognitive and motor outcomes in very preterm born infants

BACKGROUND

This study aimed to identify which MRI and clinical assessments, alone or in combination, from (i) early (32 weeks postmenstrual age, PMA), (ii) term equivalent age (TEA) and (iii) 3 months corrected age (CA) are associated with motor or cognitive outcomes at 2 years CA in infants born <31 weeks gestation.

METHODS

Prospective cohort study of 98 infants who underwent early and TEA MRI (n = 59 males; median birth gestational age 28 + 5 weeks). Hammersmith Neonatal Neurological Examination (HNNE), NICU Neonatal Neurobehavioural Scale and General Movements Assessment (GMs) were performed early and at TEA. Premie-Neuro was performed early and GMs, Test of Infant Motor Performance and visual assessment were performed at TEA and 3 months CA. Neurodevelopmental outcomes were determined using Bayley Scales of Infant and Toddler Development 3rd edition.

RESULTS

The best combined motor outcome model included 3-month GMs (β = -11.41; 95% CI = -17.34, -5.49), TEA MRI deep grey matter score (β = -6.23; 95% CI = -9.47, -2.99) and early HNNE reflexes (β = 3.51; 95% CI = 0.86, 6.16). Combined cognitive model included 3-month GMs (β = -10.01; 95% CI = -15.90, -4.12) and TEA HNNE score (β = 1.33; 95% CI = 0.57, 2.08).

CONCLUSION

Early neonatal neurological assessment improves associations with motor outcomes when combined with term MRI and 3-month GMs. Term neurological assessment combined with 3-month GMs improves associations with cognitive outcomes.

IMPACT

We present associations between 32- and 40-week MRI, comprehensive clinical assessments and later 2-year motor and cognitive outcomes for children born <31 weeks gestation. MRI and clinical assessment of motor, neurological and neurobehavioural function earlier than term equivalent age in very preterm infants is safe and becoming more available in clinical settings. Most of these children are discharged from hospital before term age and so completing assessments prior to discharge can assist with follow up. MRI and neurological assessment prior to term equivalent age while the child is still in hospital can provide earlier identification of children at highest risk of adverse outcomes and guide follow-up screening and intervention services.

Reduced ccl11/eotaxin mediates the beneficial effects of environmental stimulation on the aged hippocampus

A deterioration in cognitive performance accompanies brain aging, even in the absence of neurodegenerative pathologies. However, the rate of cognitive decline can be slowed down by enhanced cognitive and sensorimotor stimulation protocols, such as environmental enrichment (EE). Understanding how EE exerts its beneficial effects on the aged brain pathophysiology can help in identifying new therapeutic targets. In this regard, the inflammatory chemokine ccl11/eotaxin-1 is a marker of aging with a strong relevance for neurodegenerative processes. Here, we demonstrate that EE in both elderly humans and aged mice decreases circulating levels of ccl11. Interfering, in mice, with the ccl11 decrease induced by EE ablated the beneficial effects on long-term memory retention, hippocampal neurogenesis, activation of local microglia and of ribosomal protein S6. On the other hand, treatment of standard-reared aged mice with an anti-ccl11 antibody resulted in EE-like improvements in spatial memory, hippocampal neurogenesis, and microglial activation. Taken together, our findings point to a decrease in circulating ccl11 concentration as a key mediator of the enhanced hippocampal function resulting from exposure to EE.

Pre-symptomatic intervention for autism spectrum disorder (ASD): defining a research agenda

Autism spectrum disorder (ASD) impacts an individual's ability to socialize, communicate, and interact with, and adapt to, the environment. Over the last two decades, research has focused on early identification of ASD with significant progress being made in understanding the early behavioral and biological markers that precede a diagnosis, providing a catalyst for pre-symptomatic identification and intervention. Evidence from preclinical trials suggest that intervention prior to the onset of ASD symptoms may yield more improved developmental outcomes, and clinical studies suggest that the earlier intervention is administered, the better the outcomes. This article brings together a multidisciplinary group of experts to develop a conceptual framework for behavioral intervention, during the pre-symptomatic period prior to the consolidation of symptoms into diagnosis, in infants at very-high-likelihood for developing ASD (VHL-ASD). The overarching goals of this paper are to promote the development of new intervention approaches, empirical research, and policy efforts aimed at VHL-ASD infants during the pre-symptomatic period (i.e., prior to the consolidation of the defining features of ASD).

COpenhagen Neuroplastic TRaining Against Contractures in Toddlers (CONTRACT): protocol of an open-label randomised clinical trial with blinded assessment for prevention of contractures in infants with high risk of cerebral palsy

INTRODUCTION

Contractures are frequent causes of reduced mobility in children with cerebral palsy (CP) already at the age of 2-3 years. Reduced muscle use and muscle growth have been suggested as key factors in the development of contractures, suggesting that effective early prevention may have to involve stimuli that can facilitate muscle growth before the age of 1 year. The present study protocol was developed to assess the effectiveness of an early multicomponent intervention, CONTRACT, involving family-oriented and supervised home-based training, diet and electrical muscle stimulation directed at facilitating muscle growth and thus reduce the risk of contractures in children at high risk of CP compared with standard care.

METHODS AND ANALYSIS

A two-group, parallel, open-label randomised clinical trial with blinded assessment (n=50) will be conducted. Infants diagnosed with CP or designated at high risk of CP based on abnormal neuroimaging or absent fidgety movement determined as part of General Movement Assessment, age 9-17 weeks corrected age (CA) will be recruited. A balanced 1:1 randomisation will be made by a computer. The intervention will last for 6 months aiming to support parents in providing daily individualised, goal-directed activities and primarily in lower legs that may stimulate their child to move more and increase muscle growth. Guidance and education of the parents regarding the nutritional benefits of docosahexaenic acid (DHA) and vitamin D for the developing brain and muscle growth will be provided. Infants will receive DHA drops as nutritional supplements and neuromuscular stimulation to facilitate muscle growth. The control group will receive standard care as offered by their local hospital or community. Outcome measures will be taken at 9, 12, 18, 24, 36 and 48 months CA. Primary and secondary outcome measure will be lower leg muscle volume and stiffness of the triceps surae musculotendinous unit together with infant motor profile, respectively.

Poly (I:C)-induced maternal immune activation modifies ventral hippocampal regulation of stress reactivity: prevention by environmental enrichment

Environmental enrichment (EE) has been successfully implemented in human rehabilitation settings. However, the mechanisms underlying its success are not understood. Incorporating components of EE protocols into our animal models allows for the exploration of these mechanisms and their role in mitigation. Using a mouse model of maternal immune activation (MIA), the present study explored disruptions in social behavior and associated hypothalamic pituitary adrenal (HPA) axis functioning, and whether a supportive environment could prevent these effects. We show that prenatal immune activation of toll-like receptor 3, by the viral mimetic polyinosinic-polycytidylic acid (poly(I:C)), led to disrupted maternal care in that dams built poorer quality nests, an effect corrected by EE housing. Standard housed male and female MIA mice engaged in higher rates of repetitive rearing and had lower levels of social interaction, alongside sex-specific expression of several ventral hippocampal neural stress markers. Moreover, MIA males had delayed recovery of plasma corticosterone in response to a novel social encounter. Enrichment housing, likely mediated by improved maternal care, protected against these MIA-induced effects. We also evaluated c-Fos immunoreactivity associated with the novel social experience and found MIA to decrease neural activation in the dentate gyrus. Activation in the hypothalamus was blunted in EE housed animals, suggesting that the putative circuits modulating social behaviors may be different between standard and complex housing environments. These data demonstrate that augmentation of the environment supports parental care and offspring safety/security, which can offset effects of early health adversity by buffering HPA axis dysregulation. Our findings provide further evidence for the viability of EE interventions in maternal and pediatric settings.

Parents' Perspectives on a Computer Game-Assisted Rehabilitation Program for Manual Dexterity in Children With Cerebral Palsy: Qualitative Analysis of Expectations, Child Engagement, and Benefits

Background

Children with motor impairments affecting the upper extremity benefit from task-specific therapy, such as constraint-induced movement therapy. However, there is a need to improve engagement and compliance with task-specific exercise programs that target manual dexterity for children with cerebral palsy (CP). A computer game–based rehabilitation (GRP) platform was developed that combines fine manipulation and gross movement exercises with engaging game activities appropriate for young children with CP.

Objective

The objectives of this qualitative analysis were to compare parents’ perspectives and opinions about expectations, challenges, and benefits between 2 interventions.

Methods

A mixed methods, randomized controlled trial (RCT) was conducted to examine the feasibility and estimate the effect size of 2 exercise programs for rehabilitation of manual dexterity of children with CP using either GRP or conventional therapy. Parents of 26 of the children who completed the GRP program (n=33) and parents of 15 of the children who completed the conventional therapy program (n=27) participated in the interviews. A general conductive approach was used to analyze the data recorded during the parents’ interviews.

Results

Five themes captured the range of the parent’s experiences, viewpoints, and ideas: (1) parents’ expectations, (2) child’s engagement with therapy, (3) positive effects of the interventions, (4) challenges, and (5) improving the protocol.

Conclusions

Parents from both groups recognized that their expectations related to improving children’s object handling and manipulation skills including participation in activities of daily life were addressed during the 16-week therapy program. Parents perceived a change in the children’s level of independence in their daily tasks at home, school, and leisure activities.

How Does the Cause of Infantile Hemiparesis Influence Other Conditioning Factors? A Preliminary Study in a Spanish Population

Infantile hemiparesis may be associated with significant morbidity and may have a profound impact on a child’s physical and social development. Infantile hemiparesis is associated with motor dysfunction as well as additional neurologic impairments, including sensory loss, mental retardation, epilepsy, and vision, hearing, or speech impairments. The objective of this study was to analyze the association between the cause of infantile hemiparesis and birth (gestational age), age of diagnosis, and associated disorders present in children with infantile hemiparesis aged 0 to 3 years. An observational and cross-sectional study was performed. A simple and anonymous questionnaire was created ad hoc for parents of children diagnosed with infantile hemiparesis aged between 0 and 3 years about the situation regarding the diagnosis of hemiparesis, birth, cause of hemiparesis, and presence of other associated disorders. Perinatal stroke (60.1%) was the most common cause of hemiparesis, and the most typical associated disorder was epilepsy (34.2%), with the second largest percentage in this dimension corresponding to an absence of associated disorders (20.7%). The most frequent birth was “no premature” (74.1%). The mean age of diagnosis of infantile hemiparesis was registered at 8 months (IQR: 0–36). Knowing the possible association between different conditioning factors and the cause of infantile hemiparesis facilitates the prevention of severe sequelae in children and family, implementing an early comprehensive therapeutic approach in children with infantile hemiparesis.

Parental Adherence to Home Activities in Early Intervention for Young Children With Delayed Motor Development

OBJECTIVE

The purpose of this study was to investigate the relationship between characteristics of home activities and coaching practices with the adherence of parents of children with motor delays to home activities provided by physical therapists and occupational therapists in early intervention.

METHODS

An online survey study was developed and distributed to physical therapists and occupational therapists across the United States. A survey flier was posted online in parent support groups, physical and occupational therapy groups, newsletters, and organizations supporting parents of children with disabilities.

RESULTS

A total of 720 respondents participated in the survey, and 446 participants from 49 states met the inclusion criteria and were included in the analysis. Parents indicated that physical therapists and occupational therapists applied the 5 coaching practices (joint planning, observation, practice, reflection, and feedback). However, parents (63%) reported more time was needed on coaching. Parents stated that therapists' modeling the activities was the most helpful teaching technique that enhanced their adherence to home activities. Coaching practices, appropriateness of the home activities to daily routines and home environment, provision of home activities enjoyed by the child, and parent self-efficacy were all significantly associated with adherence to home activities.

CONCLUSIONS

Parents' adherence to home activities is affected not only by the type of coaching used by the therapists but also by the characteristics of the home activities provided for young children with delayed motor development.

IMPACT

The results of this study provide additional evidence supporting individualization of home activities to promote parents' continuous provision of learning opportunities to promote their children's development. There was also support of the therapists' use of the 5 coaching practices in early intervention to support the parent's application of home activities when the therapists are not present.

LAY SUMMARY

This study explored the use of home activities from the parents' perspective and provided valuable recommendations to therapists to improve parents' adherence to the recommended home activities in early intervention.

A normal motor development in congenital hydrocephalus after Cuevas Medek Exercises as early intervention: A case report

Cuevas Medek Exercises (CME) harnesses optimal scientific parameters for rehabilitation programs, and this may explain its neuroplastic outcomes. A normal motor development in a high risk of delay hydrocephalus case after CME as early intervention indicates it may be considered as research subject and treatment option to prevent motor delays.

Therapeutic efficacy of environmental enrichment on behavioral, endocrine, and synaptic alterations in an animal model of maternal immune activation

Maternal immune activation (MIA) has been identified as a significant risk factor for several neurodevelopmental disorders. We have previously demonstrated that postpubertal environmental enrichment (EE) rescues and promotes resiliency against MIA in male rats. Importantly, EE protocols have demonstrated clinical relevancy in human rehabilitation settings. Applying some of the elements of these EE protocols (e.g. social, physical, cognitive stimulation) to animal models of health and disease allows for the exploration of the mechanisms that underlie their success. Here, using a MIA model, we further investigate the rehabilitative potential of complex environments with a focus on female animals. Additionally, we expand upon some of our previous work by exploring genetic markers of synaptic plasticity and stress throughout several brain regions of both sexes. In the current study, standard housed female Sprague-Dawley rats were challenged with either the inflammatory endotoxin lipopolysaccharide (LPS; 100 μg/kg) or saline (equivolume) on gestational day 15. On postnatal day 50, male and female offspring were randomized into one of three conditions that differed in terms of cage size, number of cage mates (social stimulation) and enrichment materials. Spatial discrimination ability and social behavior were assessed six weeks later. Similar to our previously published work in males, our results revealed that a single LPS injection during mid gestation disrupted spatial discrimination ability in female rats. Postpubertal EE rescued this disruption. On the endocrine level, EE dampened elevations in plasma corticosterone that followed MIA, which may mediate EE's rehabilitative effects in female offspring. Within the prefrontal cortex, hippocampus, amygdala, and hypothalamus, MIA and EE altered the mRNA expression of several genes associated with resiliency and synaptic plasticity in both sexes. Overall, our findings provide further evidence that EE may serve as a therapeutic intervention for MIA-induced behavioral and cognitive deficits. Moreover, we identify some sexually dimorphic molecular mechanisms that may underlie these impairments and their rescue.

Early Diagnosis and Classification of Cerebral Palsy: An Historical Perspective and Barriers to an Early Diagnosis

Since the 1800s, there have been calls in the literature for the early diagnosis of cerebral palsy (CP). However, diagnosis still often occurs late, from 12 to 24 months in high income countries and as late as 5 years in low resource settings. This is after the optimal timeframe for applying interventions which could harness neuroplastic potential in the developing brain. Multiple barriers exist which affect clinicians' confidence in diagnosing CP early. These range from the lack of definitive biomarkers to a lack of curative treatments for CP. Further barriers to diagnosis are proposed including; (a) difficulty finding a congruent fit with the definition of CP in an infant, where expected activity limitations might not yet be apparent; and (b) differences in the presentation of motor type and topography classifications between infants and children. These barriers may affect a clinicians' confidence using "pattern recognition" in the differential diagnosis process. One of the central tenets of this paper is that diagnosis and classification are different, involving different instruments, and are more accurately conducted separately in infants, whereas they are fundamentally interconnected in older children and inform therapeutic decisions. Furthermore, we need to be careful not to delay early diagnosis because of the low reliability of early classification, but instead uncouple these two processes. Ongoing implementation of best practice for early detection requires creative solutions which might include universal screening for CP. Implementation and accompanying knowledge translation studies are underway to decrease the average age of diagnosis in CP.

Early Intervention Therapy Services for Infants With or at Risk for Cerebral Palsy

OBJECTIVE

The purpose of this study was to explore the practices physical therapists and occupational therapists use in early intervention (EI) for infants with or at risk for cerebral palsy (CP).

METHODS

A survey was disseminated nationally to EI providers using an online anonymous link.

RESULTS

Two hundred sixty-nine therapists completed at least 50% of the survey. Four percent of therapists use the General Movement Assessment to predict CP, 57% reported infants at risk for CP receive therapy once a week, 89% identified parents' goals as the most important factor in customizing the EI program, and 75% provide parents with home programs. However, 73% never or rarely use outcome measures to prioritize parents' goals; 31% provide parents with individualized home program and more than 60% never assess environmental enrichment.

CONCLUSION

Therapists do not incorporate sufficient strategies for goal-oriented interventions, comprehensive parent education, and optimum environmental enrichment.

Utilisation of coaching practices in early interventions in children at risk of developmental disability/delay: a systematic review

Background: To conduct a systematic review of early intervention programs (0-5 years) utilising coaching practice characteristics, to identify (i) implementation fidelity; (ii) parent training processes, and (iii) outcome measures of capacity building in parents. The coaching practice characteristics of (1) joint planning, (2) observation, (3) action/practice, (4) reflection and (5) feedback identified by Rush and Shelden were utilised.Method: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed. A comprehensive search of 6 electronic databases was undertaken in March 2016 and updated in February 2018.Results: Of 2397 articles, 18 papers met full inclusion criteria. Of these, 5 were randomised controlled trials. Only one specifically evaluated the impact of parent coaching versus therapist only delivered interventions. Risk of bias and study quality using Downs and Black checklist for clinical trial quality yielded the following descriptive ratings: Seven studies: "Poor" (scores 1-13); Six studies: "Fair" (scores 15-17); and five "Good" (scores 20-24).Conclusion: Coaching in early intervention is well accepted. Nevertheless, this review identified a continued lack of operationalised definitions; inconsistency in the reporting of therapist training and adherence to active ingredients/coaching principles; and an absence of outcome measures focused on parent capacity.Implications for RehabilitationContemporary early intervention services recognise the importance of engaging parents as active participators in their child's development. This is evident by the increase in interventions that utilise parent coaching practices. The findings of this systematic review indicate the need for professionals to:•Describe and document fidelity of coaching practices in the delivery of intervention.•Objectively measure changes in parent capacity and self-efficacy as a result of the coaching based intervention.The reporting of parent capacity measures will allow us to truly examine the effectiveness of coaching practices in empowering families to support their child to realise their full potential.

Parent-Infant Interaction during the First Year of Life in Infants at High Risk for Cerebral Palsy: A Systematic Review of the Literature

Introduction

Perinatal adverse events put neonates at high risk for short and long-term disabilities, including cerebral palsy (CP). The most recent guidelines about early intervention in infants with brain damage have emphasized the importance of family involvement from the very first phases of development. Early parent-infant interactions are pivotal in promoting infant cognitive and social developmental trajectories. However, little is known about the extent to which severe adverse perinatal events can affect the quality of early parent-infant interactions.

Patients and Methods

We systematically searched five databases (PubMed, PsycINFO, EMBASE, CINAHL, and Cochrane Library) for the publications assessing parent-infant interactions in infants at high neurological risk within 1 year of age. Articles were selected if they involved direct comparison between high-risk populations and healthy controls or low-risk populations, and if quantitative or semiquantitative tools were used to assess the parent-infant interaction. Measures of parent-infant interaction included infant interactive behaviors, parental interactive behaviors, and dyadic interactive patterns.

Results

The search yielded 18 publications that met the inclusion criteria. The articles represent a high level of heterogeneity in terms of infant neurological risk, infant age, and tools assessing interactive behaviors. Both infant and maternal behaviors within the investigated interactive exchanges were reported to be compromised, leading to subsequent overall impairment of the dyadic patterns.

Conclusion

While the studies reviewed here provide general and important information, the review did not yield a clear picture of early dyadic interactions in high-risk infant populations. Further observational studies are warranted in order to provide a more accurate knowledge of the early dyadic exchanges between infants at high neurological risk and their parents, as they might provide a critical opportunity for early family centered habilitative interventions.

Emergent Prophylactic, Reparative and Restorative Brain Interventions for Infants Born Preterm With Cerebral Palsy

Worldwide, an estimated 15 million babies are born preterm (<37 weeks' gestation) every year. Despite significant improvements in survival rates, preterm infants often face a lifetime of neurodevelopmental disability including cognitive, behavioral, and motor impairments. Indeed, prematurity remains the largest risk factor for the development of cerebral palsy. The developing brain of the preterm infant is particularly fragile; preterm babies exhibit varying severities of cerebral palsy arising from reductions in both cerebral white and gray matter volumes, as well as altered brain microstructure and connectivity. Current intensive care therapies aim to optimize cardiovascular and respiratory function to protect the brain from injury by preserving oxygenation and blood flow. If a brain injury does occur, definitive diagnosis of cerebral palsy in the first few hours and weeks of life is difficult, especially when the lesions are subtle and not apparent on cranial ultrasound. However, early diagnosis of mildly affected infants is critical, because these are the patients most likely to respond to emergent treatments inducing neuroplasticity via high-intensity motor training programs and regenerative therapies involving stem cells. A current controversy is whether to test universal treatment in all infants at risk of brain injury, accepting that some patients never required treatment, because the perceived potential benefits outweigh the risk of harm. Versus, waiting for a diagnosis before commencing targeted treatment for infants with a brain injury, and potentially missing the therapeutic window. In this review, we discuss the emerging prophylactic, reparative, and restorative brain interventions for infants born preterm, who are at high risk of developing cerebral palsy. We examine the current evidence, considering the timing of the intervention with relation to the proposed mechanism/s of action. Finally, we consider the development of novel markers of preterm brain injury, which will undoubtedly lead to improved diagnostic and prognostic capability, and more accurate instruments to assess the efficacy of emerging interventions for this most vulnerable group of infants.

Family-Centered Early Intervention Program for Brazilian Infants with Congenital Zika Virus Syndrome: A Pilot Study

Aims: To evaluate the effects of a 16-week program based on Goals-Activity-Motor Enrichment (GAME) principles on infants with congenital Zika virus syndrome (CZS)'s mother report of functional goal achievement, motor and cognitive abilities, home enrichment, and parents' perceptions regarding the service provided. Methods: Quasi-experimental study with infants (n = 32) with CZS and their mothers. Twenty-two infants composed the GAME-based group and 10 were included in the control group. The primary outcome measure was the Canadian Occupational Performance Measure. Secondary outcome measures were the Bayley Scales of Infant and Toddler Development, the Affordances in the Home Environment for Motor Development-Infant Scale, and the Measure of Processes of Care. All measures were performed by blinded assessors. Results: Mothers of infants in the GAME-based group reported significant improvements in their infants' performance on functional priorities (p = 0.0001) and satisfaction with their infants' performance (p = 0.0001), the extent in which services promoted enabling and partnership (p = 0.021), provided general information (p = 0.039), specific information (p = 0.0001), and an enriched home environment (p = 0.0001). Infants in both groups did not improve in motor or cognitive abilities. Conclusions: A family-centered early intervention program based on GAME principles improved mothers' individualized outcomes and enriched infants with CZS's environment. Future studies should elucidate long-term benefits of interventions for this population.

iMOVE: Intensive Mobility training with Variability and Error compared to conventional rehabilitation for young children with cerebral palsy: the protocol for a single blind randomized controlled trial

BACKGROUND

Cerebral palsy (CP) is the most common cause of physical disability in children. The best opportunity to maximize lifelong independence is early in motor development when there is the most potential for neuroplastic change, but how best to optimize motor ability during this narrow window remains unknown. We have systematically developed and pilot-tested a novel intervention that incorporates overlapping principles of neurorehabilitation and infant motor learning in a context that promotes upright mobility skill and postural control development. The treatment, called iMOVE therapy, was designed to allow young children with CP to self-initiate motor learning experiences similar to their typically developing peers. This manuscript describes the protocol for a subsequent clinical trial to test the efficacy of iMOVE therapy compared to conventional therapy on gross motor development and other secondary outcomes in young children with CP.

METHODS

The study is a single-blind randomized controlled trial. Forty-two participants with CP or suspected CP between the ages of 1-3 years will be randomized to receive either the iMOVE or conventional therapy group. Distinguishing characteristics of each group are detailed. Repeated measures of gross motor function will be collected throughout the 12-24 week intervention phase and at three follow-up points over one year post therapy. Secondary outcomes include measures of postural control, physical activity, participation and caregiver satisfaction.

DISCUSSION

This clinical trial will add to a small, but growing, body of literature on early interventions to optimize the development of motor control in young children with CP. The information learned will inform clinical practice of early treatment strategies and may contribute to improving the trajectory of motor development and reducing lifelong physical disability in individuals with CP.

Early intervention program for very low birth weight preterm infants and their parents: a study protocol

BACKGROUND

Preterm infants are high risk for delayed neurodevelopment. The main goal is to develop a program of early intervention for very preterm infants that allows families to apply it continuously at home, and quantify the results of early parental stimulation on improvement of cognition and motor skills.

METHODS

Randomized clinical Trial including inborn preterm infants with gestational age less than 32 weeks or birth weight less than 1500 g at 48 h after birth. Eligible for begin the intervention up to 7 days after birth. Study Protocol approved by the Brazilian national Committee of ethics in Research and by the institutional ethics committee. Intervention group (IG): skin-to skin care by mother (kangaroo care) plus tactile-kinesthetic stimulation by mothers from randomization until hospital discharge when they receive a program of early intervention with 10 parents' orientation and a total of 10 home visits independently of the standard evaluation and care that will be performed. Systematic early intervention program will be according to developmental milestones, anticipating in a month evolutionary step acquisition of motor and / or cognitive expected for corrected age. Active comparator with a Conventional Group (CG): standard care according to the routine care of the NICU and their needs in the follow up program. Neurodevelopment outcome with blinded evaluations in both groups between 12 and 18 months by Bayley Scales of Infant and Toddler Development third edition and Alberta Motor Infant scale will be performed. All evaluations will be conducted in the presence of parents or caregivers in a safe room for the child move around during the evaluation.

DISCUSSION

If we can show that a continuous and global early intervention at home performed by low income families is better than the standard care for very preterm infants, this kind of program may be applied elsewhere in the world.

Community-based parent-delivered early detection and intervention programme for infants at high risk of cerebral palsy in a low-resource country (Learning through Everyday Activities with Parents (LEAP-CP): protocol for a randomised controlled trial

INTRODUCTION

Cerebral palsy (CP) is the most common childhood physical disability, with 80% estimated to be in low-middle-income countries. This study aims to (1) determine the accuracy of General Movements (GMs)/Hammersmith Infant Neurological Examination (HINE) for detecting CP at 18 months corrected age (CA); (2) determine the effectiveness of a community-based parent-delivered early intervention for infants at high risk of CP in West Bengal, India (Learning through Everyday Activities with Parents for infants with CP; LEAP-CP).

METHODS

This study comprises two substudies: (1) a study of the predictive validity of the GMs and HINE for detecting CP; (2) randomised, double-blinded controlled trial of a novel intervention delivered through peer trainers (Community Disability Workers, CDW) compared with health advice (15 fortnightly visits). 142 infants at high risk of CP ('absent fidgety' GMs; 'high risk score' on HINE) aged 12-40 weeks CA will be recruited to the intervention substudy, with infants randomised based on a computer-generated sequence. Researchers will be masked to group allocation, and caregivers and CDWs naïve to intervention status. Visits will include therapeutic modules (goal-directed active motor/cognitive strategies and LEAP-CP games) and parent education. Health advice is based on the Integrated Management of Childhood Illness, WHO. Infants will be evaluated at baseline, post intervention and 18 months CA. The primary hypothesis is that infants receiving LEAP-CP will have greater scaled scores on the Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (mobility domain) at 18 months compared with health advice. Secondary outcomes include infant functional motor, cognitive, visual and communication development; infant growth; maternal mental health.

ETHICS AND DISSEMINATION

This study is approved through appropriate Australian and Indian ethics committees (see in text) with families providing written informed consent. Findings from this trial will be disseminated through peer-reviewed journal publications and conference presentations.

Addition of an educational programme for primary caregivers to rehabilitation improves self-care and mobility in children with cerebral palsy: a randomized controlled trial

OBJECTIVE

To assess whether the addition of an education programme for primary caregivers to rehabilitation improves daily functioning in children with cerebral palsy.

DESIGN

A randomized, single-blind, controlled study.

SETTING

This study was conducted in a rehabilitation centre in Salvador, Brazil.

PARTICIPANTS

A total of 63 boys and girls with cerebral palsy, at 1-12 years of age, with Gross Motor Function Classification Systems I-V, were randomly assigned to two groups: educational programme for primary caregivers and conventional rehabilitation ( n = 29) or conventional rehabilitation alone ( n = 31).

INTERVENTION

Each group received 12 sessions of 30 minutes of conventional rehabilitation and 12 sessions of 45 minutes to intervention group.

MEASUREMENTS

Gross Motor Function Classification System, Gross Motor Function Measure and daily functioning with the Pediatric Evaluation of Disability Inventory were assessed by a blinded assessor. The clinical outcomes were obtained at the completion of treatment (12 weeks).

RESULTS

Of the 63 patients included, 60 (mean ± SD age: 4.6 ± 2.74 years) completed the protocol. The combined education and rehabilitation, as compared with conventional rehabilitation alone, yielded significantly greater benefit in the self-care domain of the Functional Skills Scale (mean change 1.74 versus 5; P = 0.001), self-care (mean change 5.52 versus 13.99; P = 0.017) and the mobility domain of the Caregiver Assistance Scale of Pediatric Evaluation of Disability Inventory (mean change 0.87 versus 17.88; P = 0.002).

CONCLUSION

Self-care and mobility improved in children with cerebral palsy with the addition to conventional rehabilitation of an educational programme for primary caregivers.

Early Intensive Leg Training to Enhance Walking in Children With Perinatal Stroke: Protocol for a Randomized Controlled Trial

BACKGROUND

Development of motor pathways is modulated by activity in these pathways, when they are maturing (ie, critical period). Perinatal stroke injures motor pathways, including the corticospinal tracts, reducing their activity and impairing motor function. Current intervention for the lower limb emphasizes passive approaches (stretching, braces, botulinum toxin injections). The study hypothesis was that intensive, early, child-initiated activity during the critical period will enhance connectivity of motor pathways to the legs and improve motor function.

OBJECTIVE

The study objective was to determine whether early intervention with intensive activity is better than standard care, intervention delivered during the proposed critical period is better than after, and the outcomes are different when the intervention is delivered by a physical therapist in an institution vs. a parent at home.

DESIGN

A prospective, delay-group, single-blind, randomized controlled trial (RCT) and a parallel, cohort study of children living beyond commuting distance and receiving an intervention delivered by their parent.

SETTING

The RCT intervention was provided in university laboratories, and parent training was provided in the childs home.

PARTICIPANTS

Children 8 months to 3 years old with MRI-confirmed perinatal ischemic stroke and early signs of hemiparesis.

INTERVENTION

Intensive, play-based leg activity with weights for the affected leg and foot, 1 hour/day, 4 days/week for 12 weeks.

MEASUREMENTS

The primary outcome was the Gross Motor Function Measure-66 score. Secondary outcomes were motion analysis of walking, full-day step counts, motor evoked potentials from transcranial magnetic stimulation, and patellar tendon reflexes.

LIMITATIONS

Inter-individual heterogeneity in the severity of the stroke and behavioral differences are substantial but measurable. Differences in intervention delivery and assessment scoring are minimized by standardization and training.

CONCLUSIONS

The intervention, contrary to current practice, could change physical therapy interventions for children with perinatal stroke.

Unimanual versus bimanual therapy in children with unilateral cerebral palsy: Same, same, but different

BACKGROUND

There is high-level evidence supporting constraint-induced movement therapy (CIMT) and bimanual therapy for children with unilateral cerebral palsy. Evidence-based intervention includes time-limited, goal-directed, skills-based, intensive blocks of practice based on motor learning theory.

AIM AND METHODS

Using supporting literature and clinical insight, we provide a theoretical rationale to highlight previously unreported differences between CIMT and bimanual therapy.

DISCUSSION

The current emphasis on total dosage of practice for achieving positive outcomes fails to recognise the influence of other critical concepts within motor learning. Limitations exist in the application of motor learning principles using CIMT due to its unimanual nature. CIMT is effective for development of unimanual actions brought about by implicit learning, however it is difficult to target explicit learning that is required for learning how to use two hands together. Using bimanual therapy, object properties can be adapted to trigger goal-related perceptual and cognitive processes required for children to learn to recognise when two hands are required for task completion.

CONCLUSION

CIMT and bimanual should be viewed as complementary. CIMT could be used to target unimanual actions. Once these actions are established, bimanual therapy could be used for children to learn how to use these actions for bimanual skill development.

Single blind randomised controlled trial of GAME (Goals - Activity - Motor Enrichment) in infants at high risk of cerebral palsy

BACKGROUND

Cerebral palsy (CP) is caused by a lesion in the developing infant brain. Recent neuroplasticity literature suggests that intensive, task-specific intervention ought to commence early, during the critical period of neural development.

AIMS

To determine whether "GAME" (Goals - Activity - Motor Enrichment), a motor learning, environmental enrichment intervention, is effective for improving motor skills in infants at high risk of CP.

METHODS AND PROCEDURES

Single blind randomised controlled trial of GAME versus standard care. Primary outcome was motor skills on the Peabody Developmental Motor Scales-2 (PDMS-2). Secondary outcomes included Canadian Occupational Performance Measure (COPM), Bayley Scales of Infant and Toddler Development (BSID-III) and Gross Motor Function Measure-66 (GMFM-66). Outcome assessors were masked to group allocation and data analyzed with multiple regression.

OUTCOMES AND RESULTS

All n=30 infants enrolled received the assigned intervention until 16 weeks post enrolment. At 12 months of age, n=26 completed assessments. Significant between group differences were found in raw scores on the PDMS-2 in favour of GAME (B=20.71, 95%CI 1.66-39.76, p=0. 03) and at 12 months on the total motor quotient (B=8.29, 95%CI 0.13-16.45,p =0.05). Significant between group differences favored GAME participants at 12 months on the cognitive scale of the BSID-III and satisfaction scores on the COPM.

CONCLUSION

GAME intervention resulted in advanced motor and cognitive outcomes when compared with standard care.
