“…The two-factor solution is in line with previous research. For instance, Zanella et al (2021) examined the construct validity of the PDMS-2 and reported an adequate fit for a two-factor structure, i.e., gross and fine motor development. Another recent study by Lopez Boo et al (2020) found a four-factor structure for the complete Denver II including two distinct motor factors (i.e., fine and gross motor development; Frankenburg and Dodds, 1992 ).…”

“…These findings are partly supported by previous studies. For instance, the study by Zanella et al (2021) —examining the validity and reliability of the PDMS-2 in Brazilian young children—found measurement invariance across sex. Although more research is needed, the present findings suggest ( Peter et al, 1999 ; Pin et al, 2010 ; Flensborg-Madsen and Mortensen, 2017 ; van Dokkum et al, 2018 ) that gross and fine motor scores in motor milestone assessment do not only provide a valid measure of gross and fine motor development, but they can also be used to assess and compare infant development across sex, birth weight, and gestational age.…”

“…Content validity refers to the extent to which an assessment tool adequately reflects the construct(s) it set out to measure ( Prinsen et al, 2018 ). For example, a Brazilian study by Zanella et al (2021) established content validity for the PDMS-2 through a panel of experts and health professionals. Criterion validity—specifically, concurrent validity—refers to how well an assessment tool correlates with a previously established measure ( Prinsen et al, 2018 ).…”

“…Construct validity—specifically, structural validity—refers to the degree to which the scores of an assessment tool adequately reflect the dimensionality of the construct(s) that is measured ( Prinsen et al, 2018 ). For instance, Zanella et al (2021) examined the construct validity of the PDMS-2 and provided evidence for a two-factor structure, i.e., gross and fine motor development. In another study, dos Santos Chiquetti and Valentini, 2020 found a one-factor (or unidimensional) structure for the Test of Infant Motor Performance ( Campbel, 2012 ) reflecting general motor development.…”

Is Motor Milestone Assessment in Infancy Valid and Scaled Equally Across Sex, Birth Weight, and Gestational Age? Findings From the Millennium Cohort Study

Is the assessment of motor milestones valid and scaled equivalently for all infants? It is not only important to understand if the way we use gross and fine motor scores are appropriate for monitoring motor milestones but also to determine if these scores are confounded by specific infant characteristics. Therefore, the aim of the study is to investigate the latent structure underlying motor milestone assessment in infancy and measurement invariance across sex, birth weight, and gestational age. For this study, the birth cohort data from the United Kingdom Millennium Cohort Study (MCS) was used, which includes the assessment of eight motor milestone tasks from the Denver Developmental Screening Test in 9-month-old infants (N = 18,531), depicting early motor development of the first children of generation Z. Confirmatory factor analyses showed a better model fit for a two-factor structure (i.e., gross and fine motor development) compared to a one-factor structure (i.e., general motor development), and multiple indicators multiple causes modeling revealed no differential item functioning related to sex, birth weight, and gestational age. The study provides support for the use of gross and fine motor scores when assessing motor milestones in infants—both boys and girls with different birth weights and of varying gestational ages. Further investigation into widely adopted assessment tools is recommended to support the use of valid composite scores in early childhood research and practice.

Innovative Game-Aided Rehabilitation Platform for Rehabilitation of Balance in Children With Cerebral Palsy

Introduction: Cerebral Palsy (CP) is one of the leading causes of disability globally. Children with CP often develop imbalance and gait abnormality resulting in mobility limitations. Early intervention with intensive, repetitive, task-oriented practice is the key to functional independence. However, often these intensive programs lack motivation and engagement that results in low adherence and discontinuation of physiotherapy. To address this gap, an innovative, computerized game-aided rehabilitation (CGR) platform is designed for dual-task balance training. This platform provides an integrated approach to assess and treat the balance and executive cognitive functions in young children with CP. Methodology: For the known-group validity, 50 participants (25 TD and 25 CP affected children) were recruited. Comparisons were made between the two groups for DTI and task performances to evaluate the group differences. For the pilot intervention study, 16 children with CP were recruited who were randomized into two groups viz. Conventional balance training group (CBG) and Experimental group (XG). Both group received their respective therapy thrice a week for 12 weeks. The primary outcome measures were (Peabody Developmental Motor Scale-2, Gross Motor Function Classification-88, and Pediatric Balance Scale) and CGR assessment measures [COP Analysis, Visuo-Motor (VM) tracking, and Cognitive Game (CG)].Semi-structured interview were conducted for XG participant's parents to explore their views regarding the use of CGR.iii Results: The TD group was engaged in DT whereas the CP group was struggling with balance control. For the intervention study, participants in the XG demonstrated greater improvements in all clinical and CGR outcome measures whereas the CBG demonstrated a decline in VM tracking a CG performance post-intervention. The XG parents conveyed their children's problems, their expectations, their challenges, and the positive effects of CGR balance training. Conclusion:The CGR assessment was able to differentiate between the TD and CP children's DT functional performance. The CGR balance training was found to be feasible and engaging for balance training in children with CP. The substantial improvement of balance and gross motor functions in the XG more than the CBG illustrates the effectiveness of the CGR balance training and provides baseline evidence for commencing a full-scale RCT.

Early recombinant human growth hormone treatment improves mental development and alleviates deterioration of motor function in infants and young children with Prader–Willi syndrome

Background Recombinant human growth hormone (rhGH) therapy has shown to improve height and body composition in children with Prader–Willi syndrome (PWS), the evidence of early rhGH treatment on motor and mental development is still accumulating. This study explored the time effect on psychomotor development, anthropometric indexes, and safety for infants and young children with PWS. Methods A phase 3, single-arm, multicenter, self-controlled study was conducted in six sites. Patients received rhGH at 0.5 mg/m2/day for first four weeks, and 1 mg/m2/day thereafter for up to 52 weeks. Motor development was measured using Peabody Developmental Motor Scales-second edition, mental development using Griffiths Development Scales-Chinese (GDS-C). Height standard deviation score (SDS), body weight SDS, and body mass index (BMI) SDS were also assessed. Results Thirty-five patients were enrolled totally. Significant improvements were observed in height, body weight, and BMI SDS at week 52; GDS-C score showed significant improvement in general quotient (GQ) and sub-quotients. In a linear regression analysis, total motor quotient (TMQ), gross motor quotient (GMQ), and fine motor quotient were negatively correlated with age; however, treatment may attenuate deterioration of TMQ and GMQ. Changes in GQ and locomotor sub-quotient in < 9-month group were significantly higher than ≥ 9-month group. Mild to moderate severity adverse drug reactions were reported in six patients. Conclusion Fifty-two-week treatment with rhGH improved growth, BMI, mental development, and lessened the deterioration of motor function in infants and young children with PWS. Improved mental development was more pronounced when instituted in patients < 9 months old.
