Approximately 50% of people with cerebral palsy have a cognitive impairment. However, many tools used to assess cognition in infants require almost normal fine motor ability, and thus may not accurately reflect cognitive abilities of infants with cerebral palsy or other motor impairments. This systematic review aimed to evaluate the psychometric properties of cognitive assessment tools for infants aged 0-24 months with motor impairments and to make recommendations about the most appropriate cognitive assessment tools for the purpose of discrimination, prediction, and evaluation.A systematic review was conducted. CINAHL, Embase, ERIC, Medline, PsycINFO, and SCOPUS databases were searched to identify studies reporting on 1 or more psychometric properties of a standardized cognitive assessment tool or questionnaire in a sample/subsample of infants with motor impairment. Of the 4,480 articles reviewed, 9 assessment tools were identified in 20 publications, which met our inclusion criteria. Articles were appraised using the COnsensus-based Standards for the selection of health Measurement INstruments to assess study rigor. The GRADE framework was applied to develop recommendations for clinical practice.The Mayes Motor-Free Compilation, Fagan Test of Infant Intelligence, and Bayley-III Low Motor/Vision have predictive and/or discriminative utility in this population. The Mullen Scales of Early Learning was the only tool with psychometric research available examining responsivity to change.Assessment tools with low-motor/motor-free accommodations have greater accuracy in estimating cognitive abilities of infants with motor impairment than conventional norm-referenced tests. There, however, remains a significant paucity of research in this area.
To briefly outline the strengths and limitations of cerebral palsy (CP) registers, and to report on findings of the Australian Cerebral Palsy Register (ACPR) pertaining to a population cohort of children with CP.De-identified data were extracted from the ACPR for people with CP in birth years 1993 to 2006, from South Australia, Victoria, and Western Australia. Live birth prevalence of CP was estimated and risk factors described.The overall birth prevalence of CP (including those whose CP was postneonatally acquired) for the 1993 to 2006 birth cohort was 2.1 per 1000 live births (95% confidence interval [CI] 2.0-2.2). Excluding cases with a known postneonatal cause, the birth prevalence for pre/perinatally acquired CP was 2.0 per 1000 live births (95% CI 1.9-2.1). A downward trend in rates of CP in those born extremely preterm was evident over at least three consecutive periods across all three regions. Most (58.6%) children were born at term (≥ 37 wks). Male sex, early gestational age, low birthweight, and multiple birth were risk factors for CP.Overall rates of CP did not change during this period. The proportion of those with CP born extremely preterm decreased. The ACPR Group will investigate whether this pattern continues when data pertaining to the next birth cohort for all three regions becomes available.
Purpose To understand how healthcare professionals' perceptions of supports and barriers to routine clinical assessment, for children aged 3–18 years with cerebral palsy, evolved in the presence of a knowledge translation intervention.Methods A prospective longitudinal mixed-methods study was completed. The intervention comprised knowledge brokers, an e-evidence library, locally provided education and embedding routine clinical assessment in practice. Healthcare professionals from five disability services completed the Supports and Barriers Questionnaire and focus groups at baseline, 6, 12 and 24 months. Quantitative data were analysed descriptively and qualitative data using longitudinal framework analysis.Results Questionnaire ratings indicated participants felt supported in implementing routine assessment over time. Subtle differences emerged from the longitudinal framework analysis. Participants shifted from 'adopting' to 'embedding' and 'maintaining' routine assessment. Integration of assessment was impacted by a new national disability funding model. Participants highlighted the need to maintain skills and for unambiguous, sustained communication between the organisation, clients, and stakeholders. If, how and why families engaged with routine assessment developed over time.Conclusions After an initial focus on pragmatic implementation issues, over time healthcare professionals began to reflect more on the complexities of children and families' engagement with assessment and the impact on the therapist-child-family relationship. Trial registration: This trial was not a controlled healthcare intervention and was registered retrospectively: ACTRN12616001616460. The protocol of the trial was published in 2015.IMPLICATIONS FOR REHABILITATIONHealthcare professionals can be supported over time to embed routine clinical assessment using multifaceted knowledge translation interventions.It takes time and ongoing support for healthcare professionals to embed, maintain and begin to adapt the routine clinical assessment to fit with policy, organisational context and the needs and wishes of children and families.Understanding and tailoring knowledge translation approaches to the policy context are essential.Even in the context of major policy shifts, it is possible to harness the commitment of organisations and professionals to improve their services in line with evidence-based approaches.
Cerebral palsy describes the most common physical disability in childhood and occurs in 1 in 500 live births. Historically, the diagnosis has been made between age 12 and 24 months but now can be made before 6 months’ corrected age.
Objectives
To systematically review best available evidence for early, accurate diagnosis of cerebral palsy and to summarize best available evidence about cerebral palsy–specific early intervention that should follow early diagnosis to optimize neuroplasticity and function.
Evidence Review
This study systematically searched the literature about early diagnosis of cerebral palsy in MEDLINE (1956-2016), EMBASE (1980-2016), CINAHL (1983-2016), and the Cochrane Library (1988-2016) and by hand searching. Search terms includedcerebral palsy,diagnosis,detection,prediction,identification,predictive validity,accuracy,sensitivity, andspecificity. The study included systematic reviews with or without meta-analyses, criteria of diagnostic accuracy, and evidence-based clinical guidelines. Findings are reported according to the PRISMA statement, and recommendations are reported according to the Appraisal of Guidelines, Research and Evaluation (AGREE) II instrument.
Findings
Six systematic reviews and 2 evidence-based clinical guidelines met inclusion criteria. All included articles had high methodological Quality Assessment of Diagnostic Accuracy Studies (QUADAS) ratings. In infants, clinical signs and symptoms of cerebral palsy emerge and evolve before age 2 years; therefore, a combination of standardized tools should be used to predict risk in conjunction with clinical history. Before 5 months’ corrected age, the most predictive tools for detecting risk are term-age magnetic resonance imaging (86%-89% sensitivity), the Prechtl Qualitative Assessment of General Movements (98% sensitivity), and the Hammersmith Infant Neurological Examination (90% sensitivity). After 5 months’ corrected age, the most predictive tools for detecting risk are magnetic resonance imaging (86%-89% sensitivity) (where safe and feasible), the Hammersmith Infant Neurological Examination (90% sensitivity), and the Developmental Assessment of Young Children (83% C index). Topography and severity of cerebral palsy are more difficult to ascertain in infancy, and magnetic resonance imaging and the Hammersmith Infant Neurological Examination may be helpful in assisting clinical decisions. In high-income countries, 2 in 3 individuals with cerebral palsy will walk, 3 in 4 will talk, and 1 in 2 will have normal intelligence.
Conclusions and Relevance
Early diagnosis begins with a medical history and involves using neuroimaging, standardized neurological, and standardized motor assessments that indicate congruent abnormal findings indicative of cerebral palsy. Clinicians should understand the importance of prompt referral to diagnostic-specific early intervention to optimize infant motor and cognitive plasticity, prevent secondary complications, and enhance caregiver well-being.
Umbilical cord blood (UCB) infusion is being investigated as a treatment for a range of neurological conditions, primarily because of its potent immunomodulatory effects mediated via paracrine signaling. Although initial research mainly utilized autologous UCB, allogeneic samples from a sibling or unrelated donor have now become more common. With the use of allogeneic UCB, questions have arisen surrounding the necessity for human leukocyte antigen (HLA) matching, preparative regimens and immunosuppressant drugs. To investigate the safety of allogeneic UCB for the treatment of neurological conditions and the impact of HLA mismatching and immunosuppresion, the authors conducted a systematic review of the safety of allogeneic UCB infusion for neurological conditions.A systematic review of published and gray literature was conducted to investigate the safety of allogeneic UCB infusions for neurological conditions.Authors identified 10 studies using allogeneic UCB to treat autism spectrum disorder, cerebral palsy, stroke, traumatic brain injury and various other conditions. A total of 361 participants (with at least 442 UCB infusions) received a range of HLA-matched/untyped allogeneic units and cell doses, with the majority not administered post-infusion immunosuppression. There were no reported serious adverse events definitely or probably related to the allogeneic UCB infusion, nor later potential complications such as graft-versus-host disease or teratoma formation.Although variability between studies is high, the available data do not identify safety concerns with allogeneic UCB infusion for the treatment of neurological conditions, even with variable HLA matching or no immunosuppression.
