New Technological Approach for the Evaluation of Postural Control Abilities in Children with Developmental Coordination Disorder

Background: Developmental Coordination Disorder (DCD) causes difficulties in postural control which are crucial to assess due to their impact on everyday life. There is a lack of suitable tools to acquire quantitative data and deeply analyze postural control, especially during the developmental age. The aim of this study is to investigate postural control skills in children with DCD and typically developing children (TD) using the Virtual Reality Rehabilitation System (VRRS). Methods: 18 children with DCD and 30 TD children (mean age 9.12 +/- 2.65 and 7.12 +/- 2.77 years, respectively) were tested by using the Movement Assessment Battery for Children Second Edition (MABC-2) and a VRRS stabilometric balance platform. A t-test was performed to identify differences in the VRRS parameters between the two groups. Furthermore, we investigated whether a correlation exists between the VRRS data and the MABC-2. Results: Significant differences (p < 0.05) in mean distance and frequency of the COP are found in the two groups. These parameters also correlate with the MABC-2 total score (p <= 0.05) and balance subscales (p <= 0.05). Conclusions: This study opens a new frontier for the assessment of postural skills in children with DCD and represents a potential basis for a tailored rehabilitation program, from which their postural stability and, consequently, their everyday life will benefit

Concurrent and predictive validity of the infant motor profile in infants at risk of neurodevelopmental disorders

BACKGROUND: Preterm infants and infants with perinatal brain injury show a higher incidence of neurodevelopmental disorders (NDD). The Infant Motor Profile (IMP) is a clinical assessment which evaluates the complexity of early motor behaviour. More data are needed to confirm its predictive ability and concurrent validity with other common and valid assessments such as the Alberta Infant Motor Scale (AIMS) and Prechtl's General Movement Assessment (GMA). The present study aims to evaluate the concurrent validity of the IMP with the AIMS, to assess its association with the GMA, to evaluate how the IMP reflects the severity of the brain injury and to compare the ability of the IMP and the AIMS to predict an abnormal outcome in 5-month-old infants at risk of NDD.METHODS: 86 infants at risk of NDD were retrospectively recruited among the participants of two clinical trials. Preterm infants with or without perinatal brain injury and term infants with brain injury were assessed at 3months corrected age (CA) using the GMA and at 5months CA using the IMP and the AIMS. The neurodevelopmental outcome was established at 18months.RESULTS: Results confirm a solid concurrent validity between the IMP Total Score and the AIMS (Spearman's rho 0.76; p<.001) and a significant association between IMP Total Score and the GMA. Unlike the AIMS, the IMP Total score accurately reflects the severity of neonatal brain injury (p<.001) and proves to be the strongest predictor of NDD (p<.001). The comparison of areas under receiver operating characteristic curves (AUC) confirms that the IMP Total score has the highest diagnostic accuracy at 5months (AUC 0.92). For an optimal IMP Total Score cut-off value of 70, the assessment shows high sensitivity (93%) and specificity (81%) (PPV 84%; NPV 90%).CONCLUSIONS: Early motor behaviour assessed with the IMP is strongly associated with middle-term neurodevelopmental outcome. The present study confirms the concurrent validity of the IMP with the AIMS, its association with the GMA and its ability to reflect brain lesion load, hence contributing to the construct validity of the assessment.TRIAL REGISTRATION: NCT01990183 and NCT03234959 (clinicaltrials.gov)

Parental Practices and Environmental Differences among Infants Living in Upper-Middle and High-Income Countries: A Cross-Sectional Study

Parental practices and environmental factors can impact a child's development and, consequently, functionality. The objective is to assess the parental practices and environmental differences in healthy and at-risk infants at 3-6 months of age living in upper-middle (Brazil) and high-income (Italy) countries. A total group of 115 infants was identified and classified into four groups: healthy Italian infants (H_IT); Italian infants exposed to biological risk factors (R_IT); healthy Brazilian infants (H_BR); and Brazilian infants exposed to environmental risk factors (L_BR). The dependent variables were parental practices and environmental factors, which were assessed through a semi-structured interview and the "variety of stimulation dimension" from the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) questionnaire. Descriptive analyses, a multivariate analysis of variance (MANOVA), and correlation tests were applied. Regarding the environment and parental practices, the mother's age, maternal and paternal education, civil status, and variety of stimulation showed significant differences among the infants living in Brazil or in Italy. There were strong dissimilarities in parental practices and environmental factors among infants living in low/upper-middle and high-income countries. Since the home environment is the main stimulus for infant growth and development, our results are meaningful for providing knowledge about these two different cultures

IL RUOLO DEL DIRIGENTE NELLA PREVENZIONE DA MOVIMENTAZIONE MANUALE DEI CARICHI: analisi di alcune realtà lavorative nella riabilitazione di pazienti in età evolutiva

Il sovraccarico biomeccanico da movimentazione manuale dei carichi rappresenta un problema di grande rilevanza sociale e sanitaria nei paesi occidentali; infatti sono molti i dati e gli studi che indicano come la maggior parte della popolazione adulta soffra, di lombalgia, con intensità e ricorrenza diverse. Gli infortuni legati al lavoro non costituiscono un disagio che colpisce solo il lavoratore, ma interessano l’azienda stessa, per il semplice motivo che un lavoratore infortunato non può lavorare, o lavora con un’efficienza chiaramente ridotta. Questa patologia rappresenta così non solo un problema di salute, ma anche economico, sia in termini di costi diretti che indiretti, al punto da costituire, per assenze per malattia, cure, limitazioni dell'idoneità lavorativa e invalidità, uno dei più importanti problemi sanitari nel campo del lavoro [How D. et al., 2010]. Secondo la Sez. IV della Corte di Cassazione (sentenza n. 1238), il controllo che il dirigente deve esercitare al fine delle misure di sicurezza stabilite dall’ordinamento lavoristico, consiste nelle misure relative a informazione, formazione, attrezzature idonee, presidi di sicurezza, e comunque ogni altra misura idonea, per comune regola di prudenza e diligenza, a garantire la sicurezza nei luoghi di lavoro. Perciò la responsabilità del dirigente in quest’ambito è centrale e tanto pesante quanta è la sua libertà decisionale concorrendo in colpa con il datore di lavoro per mancanze rispetto alle disposizioni vigenti in materia di sicurezza del lavoro. L’obiettivo di questo lavoro di tesi è stato quello di promuovere la somministrazione di un questionario che andasse ad indagare il fenomeno della MMC negli operatori sanitari dell’area riabilitativa che trattassero pazienti in età evolutiva. Questo è stato possibile grazie alla collaborazione da parte degli operatori delle UFSMIE dell’Area vasta Nord-Ovest, dell’IRCCS Fondazione Stella Maris e dell’Azienda Ospedaliera Universitaria Pisana. È fondamentale dunque “Prendersi cura di chi ha cura

Assessment of Postural Control in Children with Movement Disorders by Means of a New Technological Tool: A Pilot Study

Considering the variability and heterogeneity of motor impairment in children with Movement Disorders (MDs), the assessment of postural control becomes essential. For its assessment, only a few tools objectively quantify and recognize the difference among children with MDs. In this study, we use the Virtual Reality Rehabilitation System (VRRS) for assessing the postural control in children with MD. Furthermore, 16 children (mean age 10.68 ± 3.62 years, range 4.29–18.22 years) were tested with VRRS by using a stabilometric balance platform. Postural parameters, related to the movements of the Centre of Pressure (COP), were collected and analyzed. Three different MD groups were identified according to the prevalent MD: dystonia, chorea and chorea–dystonia. Statistical analyses tested the differences among MD groups in the VRRS-derived COP variables. The mean distance, root mean square, excursion, velocity and frequency values of the dystonia group showed significant differences (p < 0.05) between the chorea group and the chorea–dystonia group. Technology provides quantitative data to support clinical assessment: in this case, the VRRS detected differences among the MD patterns, identifying specific group features. This tool could be useful also for monitoring the longitudinal trajectories and detecting post-treatment changes

Inter and intra-rater reliability and minimal detectable difference of movement disorder-childhood rating scale

Movement Disorder-Childhood Rating Scales (MD-CRS) have been designed in two forms (0-3 and 4-18 years) to accurately evaluate various movement disorders in children

Early intervention at home in infants with congenital brain lesion with CareToy revised: A RCT protocol

Background: Congenital brain lesions expose infants to be at high-risk for being affected by neurodevelopmental disorders such as cerebral palsy (CP). Early interventions programs can significantly impact and improve their neurodevelopment. Recently, in the framework of the European CareToy (CT) Project ( www.caretoy.eu ), a new medical device has been created to deliver an early, intensive, customized, intervention program, carried out at home by parents but remotely managed by expert and trained clinicians. Reviewing results of previous studies on preterm infants without congenital brain lesion, the CT platform has been revised and a new system created (CT-R). This study describes the protocol of a randomised controlled trial (RCT) aimed to evaluate, in a sample of infants at high-risk for CP, the efficacy of CT-R intervention compared to the Infant Massage (IM) intervention. Methods/design: This RCT will be multi-centre, paired and evaluator-blinded. Eligible subjects will be preterm or full-term infants with brain lesions, in first year of age with predefined specific gross motor abilities. Recruited infants will be randomized into CT-R and IM groups at baseline (T0). Based on allocation, infants will perform an 8-week programme of personalized CareToy activities or Infant Massage. The primary outcome measure will be the Infant Motor Profile. On the basis of power calculation, it will require a sample size of 42 infants. Moreover, Peabody Developmental Motor Scales-Second Edition, Teller Acuity Cards, standardized video-recordings of parent-infant interaction and wearable sensors (Actigraphs) will be included as secondary outcome measures. Finally, parents will fill out questionnaires (Bayley Social-Emotional, Parents Stress Index). All outcome measures will be carried out at the beginning (T0) and at end of 8-weeks intervention period, primary endpoint (T1). Primary outcome and some secondary outcomes will be carried out also after 2 months from T1 and at 18 months of age (T2 and T3, respectively). The Bayley Cognitive subscale will be used as additional assessment at T3. Discussion: This study protocol paper is the first study aimed to test CT-R system in infants at high-risk for CP. This paper will present the scientific background and trial methodology
