Feasibility of a caregiver-assisted exercise program for preterm infants

'I Did Not Know We Could Exercise This Small Premature Baby': Challenges Experienced by Parents While Implementing Early Intervention for Their Preterm Infants-A Qualitative Perspective

BACKGROUND

Preterm birth is a highly stressful experience for both parents and infants. Parental participation in care enhances developmental outcomes, fosters parent-infant interactions and builds parental confidence. However, low parental adherence has always been a challenge in the successful implementation of intervention programs both in the NICU and at home. It is imperative to understand parents' perspectives and view the challenges that they experience through their lens while providing early intervention to their infants born preterm. This study is aimed at identifying new parents' challenges when implementing early intervention programs for their infants during the transition from hospital to home.

METHODS

Ten parents of preterm infants trained to administer early intervention programs in the NICU and at home were recruited during their infants' 3-month follow-up. Semistructured in-depth interviews were conducted until data saturation. The audio recordings of the interviews were transcribed and translated into English. Thematic analysis, using ATLAS.ti Version 8.0 software, identified overarching challenges through deductive and inductive coding.

RESULTS

Data analysis identified five recurring themes: (1) navigating early days of parenthood, (2) nurturing resilience in infant care, (3) supporting infants through informed caregiving, (4) maximizing efficiency in infant care through time mastery and (5) balancing equity and flexibility in caregiving. Parents expressed fear of handling their infants born preterm because of their low birth weight and small size. Time constraints, changing sleep patterns and daily routines make it difficult for mothers to adhere to exercise programs. Parents also face challenges when infants exhibit stressful behaviour. Furthermore, gender differences were observed, with fathers often not continuing the program at home.

CONCLUSIONS

The study highlights parents' main challenges when providing early intervention for infants born preterm at home. It emphasizes issues related to maternal roles, family support and difficulties in infant handling, exercise and time management.

Parental Perceptions of Physical Activity and Risk of Disease Associated with Sedentary Behaviours in Infants and Toddlers

OBJECTIVES

The current study intends to measure parents' perceptions of newborn and toddler physical activity.

METHODS

A Cross-sectional study was conducted at the pediatric clinic at a University Hospital in Riyadh. The parents or guardians of children 0 to 3 years of age, healthy infants, and toddlers who visited the vaccination and pediatric clinic at a University Hospital in Riyadh, were recruited. The Parental Perceptions of Physical Activity Scale (PPPAS) was translated into the Arabic language. The Chi-square test was applied to observe the association between categorical variables. P value < 0.05 was considered to be statistically significant.

RESULTS

A total of 383 parents were recruited. There was a significant association observed between physical activity and income, employment, and education. A significant association was observed between the following perceptions; the child enjoys physical activity, it increases the child's fitness level, the strength of the muscles, flexibility, and life span, improves happiness, keeps the child active, and provides a sense of achievement, and decrease future weight problems.

CONCLUSION FOR PRACTICE

The study determined that parental inclination towards engaging in a physical activity intervention for their infants, as well as identifying any concerns that may impact their children's adherence to physical activity was satisfied.

A systematic synthesis of qualitative studies on parents' experiences of participating in early intervention programs with their infant born preterm

Early intervention programs involving both the parent and the infant born preterm have demonstrated positive effects on developmental outcomes for the children. However, studies have also shown that parental engagement and adherence when implementing intervention programs can be challenging. The aim of this review was to provide a comprehensive description and new insights into key messages gleaned from the parent reports on participating in early intervention with their infant born preterm; knowledge vital to facilitate implementation of early interventions into clinical practice when using a model of direct parent involvement. Early intervention is broadly defined as a multi-interdisciplinary field provided to children from birth to five years of age to foster child health, wellbeing, development, adapting parenting and family function. For this systematic synthesis we define early intervention as programs with specific activities completed with the infant during the first year after birth. We assembled qualitative interview studies on parents' experiences with participation in early intervention and applied Malterud's qualitative systematic meta-synthesis to synthesize and translate the original findings across studies. In the analysis we applied enactive concepts of embodiment, autonomy, participatory sensemaking, and agency. 10 qualitative studies were identified and included. The systematic synthesis reveals how parents' successful and meaningful participation in early intervention programs were facilitated by their "active embodied doing." The "embodied doing" appeared as the basis for the parents' sense-making processes, development of confidence, and the ability for parents to see new possibilities for actions within themselves, with and in the child. In that respect, a perception of mutuality in the interaction between parent, infant and interventionist was central. Consequently, an important consideration when implementing early intervention into clinical practice is to promote embodied parent-infant interactions as well as trust between the parent and the interventionist.

Design and methods for the training in exercise activities and motion for growth (TEAM 4 growth) trial: A randomized controlled trial

BACKGROUND

Growth is often impaired in infants with congenital heart disease. Poor growth has been associated with worse neurodevelopment, abnormal behavioral state, and longer time to hospital discharge. Nutritional interventions, drug therapy, and surgical palliation have varying degrees of success enhancing growth. Passive range of motion (PROM) improves somatic growth in preterm infants and is safe and feasible in infants with hypoplastic left heart syndrome (HLHS), after their first palliative surgery (Norwood procedure).

METHODS

This multicenter, Phase III randomized control trial of a 21-day PROM exercise or standard of care evaluates growth in infants with HLHS after the Norwood procedure. Growth (weight-, height- and head circumference-for-age z-scores) will be compared at 4 months of age or at the pre-superior cavopulmonary connection evaluation visit, whichever comes first. Secondary outcomes include neonatal neurobehavioral patterns, neurodevelopmental assessment, and bone mineral density. Eligibility include diagnosis of HLHS or other single right ventricle anomaly, birth at ≥37 weeks gestation and Norwood procedure at <30 days of age, and family consent. Infants with known chromosomal or recognizable phenotypic syndromes associated with growth failure, listed for transplant, or expected to be discharged within 14 days of screening are excluded.

CONCLUSIONS

The TEAM 4 Growth trial will make an important contribution to understanding the role of PROM on growth, neurobehavior, neurodevelopment, and BMD in infants with complex cardiac anomalies, who are at high risk for growth failure and developmental concerns.

A systematic review of how adherence to caregiver facilitated therapeutic activities for children are assessed and reported in published research

This systematic review assessed four measurement properties of measures (instruments) used by researchers to assess adherence to caregiver facilitated therapeutic activities (CFTA) for children in published research. The measurement properties considered in this systematic review were dyadic considerations, interpretability, reliability, and validity of the instruments used to assess adherence or compliance. Two databases (http://www.pubmed.gov and EMBASE) were searched for studies that reported adherence or compliance to CFTA prescribed by physiotherapists or occupational therapists or speech and language therapists. Papers included in this review were those that studied children less than 18 years old and or their primary caregivers. Data were extracted by the authors using a data extraction table adapted from the work of Bollen and colleagues (2014) and by rating the measurement properties of the adherence measures identified based on predefined rating criteria (see supplementary file and Table 1 respectively). The authors relied only on the published research articles and any associated published supplementary files/data. None of the 40 adherence instruments identified wholly fulfilled all the criteria of the four measurement properties assessed. The results of this systematic review show that the measures used by researchers for assessing adherence to CFTA generally lack validity, reliability, and dyadic considerations.

Physical Therapy to Prevent Osteopenia in Preterm Infants: A Systematic Review

BACKGROUND

During the last trimester of pregnancy, about 80% of the infant's calcium is incorporated, and for this reason, preterm infants have less bone mineralization compared to those born at term. The aim of the present systematic review was to identify, evaluate and summarize the studies that deal with the effect of physiotherapy modalities in the prevention and treatment of osteopenia in preterm infants.

METHODS

A comprehensive search (09/2019-02/2021) using PubMed, Web of Science, SCOPUS, ProQuest, SciELO, Latindex, ScienceDirect, PEDro and ClinicalTrials.gov was carried out. The following data were extracted: The number of participants, characteristics of the participants, design, characteristics of the intervention, outcome measures, time of evaluation and results. A non-quantitative synthesis of the extracted data was performed. The methodological quality and risk of bias were assessed using a PEDro scale and ROB-2 scale, respectively.

RESULTS

A total of 16 studies were analyzed, presenting a methodological quality that ranged from 3 to 8 points, and all showed some concerns regarding their risk of bias. Almost all studies (15/16) used passive mobilizations with joint pressure to prevent osteopenia, but they differed in the intensity and frequency of application.

CONCLUSIONS

A daily exercise program of passive mobilizations with joint pressure, improves bone mineralization in preterm infants admitted to neonatal units.

Risk of hypertension following perinatal adversity: IUGR and prematurity

Consistent with the paradigm shifting observations of David Barker and colleagues that revealed a powerful relationship between decreased weight through 2 years of age and adult disease, intrauterine growth restriction (IUGR) and preterm birth are independent risk factors for the development of subsequent hypertension. Animal models have been indispensable in defining the mechanisms responsible for these associations and the potential targets for therapeutic intervention. Among the modifiable risk factors, micronutrient deficiency, physical immobility, exaggerated stress hormone exposure and deficient trophic hormone production are leading candidates for targeted therapies. With the strong inverse relationship seen between gestational age at delivery and the risk of hypertension in adulthood trumping all other major cardiovascular risk factors, improvements in neonatal care are required. Unfortunately, therapeutic breakthroughs have not kept pace with rapidly improving perinatal survival, and groundbreaking bench-to-bedside studies are urgently needed to mitigate and ultimately prevent the tsunami of prematurity-related adult cardiovascular disease that may be on the horizon. This review highlights our current understanding of the developmental origins of hypertension and draws attention to the importance of increasing the availability of lactation consultants, nutritionists, pharmacists and physical therapists as critical allies in the battle that IUGR or premature infants are waging not just for survival but also for their future cardiometabolic health.

Development of the Parent Perceptions of Physical Activity Scale (PPPAS): Results from two studies with parents of infants and toddlers

Physical activity (PA) is important from birth to promote health and motor development. Parents of young children are gatekeepers of opportunities for PA, yet little is known about their perceptions of PA. We describe the development of the Parent Perceptions of Physical Activity Scale (PPPAS) across two studies (N = 241 parents). In Study 1, 143 parents of infants and toddlers recruited from neonatal intensive care units (NICUs) and childcare centers completed a 48-item PPPAS. In Study 2, 98 parents of premature infants completed the revised 34-item PPPAS. Study 1 principal components analysis (PCA) identified three components (benefits of, barriers to, and perceived influence on PA), and the scale was reduced. Scores for Perceived Barriers to PA were significantly different between groups, U = 1,108, z = -4.777, p < .0001, with NICU parents reporting more barriers to PA than childcare parents. In Study 2, PCA revealed the same components, and the scale was further reduced to 25 items. Three subscales measuring perceived benefits of, barriers to, and influence over an infant's PA produced Cronbach's alphas of .93, .85, .81, respectively. Results demonstrated sufficient construct validity and internal consistency of PPPAS scores, supporting its use in future PA research.

The Role of Exercise in Prevention and Treatment of Osteopenia of Prematurity: An Update

Premature infants have an increased risk of osteopenia due to limited bone mass accretion in utero and a greater need for bone nutrients. Until recently, most efforts to prevent osteopenia of prematurity focused on nutritional changes. Recent studies indicate that passive range-of-motion exercise of the extremities may lead to beneficial effects on body weight, increased bone mineralization, increased bone formation markers and leptin levels, and attenuation of the natural postnatal decline in bone speed of sound. These results suggest that exercise may play an important role in the prevention and treatment of osteopenia of prematurity. This review summarizes our current knowledge on the role of exercise in the prevention and treatment of osteopenia of prematurity.

Passive range of motion exercise to enhance growth in infants following the Norwood procedure: a safety and feasibility trial

OBJECTIVE

The aim of this study was to evaluate the safety and feasibility of a passive range of motion exercise programme for infants with CHD. Study design This non-randomised pilot study enrolled 20 neonates following Stage I palliation for single-ventricle physiology. Trained physical therapists administered standardised 15-20-minute passive range of motion protocol, for up to 21 days or until hospital discharge. Safety assessments included vital signs measured before, during, and after the exercise as well as adverse events recorded through the pre-Stage II follow-up. Feasibility was determined by the percent of days that >75% of the passive range of motion protocol was completed.

RESULTS

A total of 20 infants were enrolled (70% males) for the present study. The median age at enrolment was 8 days (with a range from 5 to 23), with a median start of intervention at postoperative day 4 (with a range from 2 to 12). The median hospital length of stay following surgery was 15 days (with a range from 9 to 131), with an average of 13.4 (with a range from 3 to 21) in-hospital days per patient. Completion of >75% of the protocol was achieved on 88% of eligible days. Of 11 adverse events reported in six patients, 10 were expected with one determined to be possibly related to the study intervention. There were no clinically significant changes in vital signs. At pre-Stage II follow-up, weight-for-age z-score (-0.84±1.20) and length-for-age z-score (-0.83±1.31) were higher compared with historical controls from two earlier trials.

CONCLUSION

A passive range of motion exercise programme is safe and feasible in infants with single-ventricle physiology. Larger studies are needed to determine the optimal duration of passive range of motion and its effect on somatic growth.

The importance of foetal movement for co-ordinated cartilage and bone development in utero : clinical consequences and potential for therapy

Construction of a functional skeleton is accomplished through co-ordination of the developmental processes of chondrogenesis, osteogenesis, and synovial joint formation. Infants whose movement in utero is reduced or restricted and who subsequently suffer from joint dysplasia (including joint contractures) and thin hypo-mineralised bones, demonstrate that embryonic movement is crucial for appropriate skeletogenesis. This has been confirmed in mouse, chick, and zebrafish animal models, where reduced or eliminated movement consistently yields similar malformations and which provide the possibility of experimentation to uncover the precise disturbances and the mechanisms by which movement impacts molecular regulation. Molecular genetic studies have shown the important roles played by cell communication signalling pathways, namely Wnt, Hedgehog, and transforming growth factor-beta/bone morphogenetic protein. These pathways regulate cell behaviours such as proliferation and differentiation to control maturation of the skeletal elements, and are affected when movement is altered. Cell contacts to the extra-cellular matrix as well as the cytoskeleton offer a means of mechanotransduction which could integrate mechanical cues with genetic regulation. Indeed, expression of cytoskeletal genes has been shown to be affected by immobilisation. In addition to furthering our understanding of a fundamental aspect of cell control and differentiation during development, research in this area is applicable to the engineering of stable skeletal tissues from stem cells, which relies on an understanding of developmental mechanisms including genetic and physical criteria. A deeper understanding of how movement affects skeletogenesis therefore has broader implications for regenerative therapeutics for injury or disease, as well as for optimisation of physical therapy regimes for individuals affected by skeletal abnormalities.
