RESUMEN
To address the research hypothesis that the Alberta Infant Motor Scale (AIMS) completed following complex cardiac surgery (CCS) is a useful outcomes measure this study determined: (1) AIMS scores at age 8 months after CCS; (2) predictive validity of AIMS at 8 months for Bayley Scales of Infant and Toddler Development-III Gross Motor-scaled scores (GMSS) and diagnosis of cerebral palsy (CP) at 21 months; and (3) predictive demographic and surgical variables of AIMS scores. A prospective cohort study of 250/271 (92.3%) surviving children from Northern Alberta (born 2009-2020) who had CCS at age < 6 months determined AIMS scores at age mean (SD) 8.6 (2.4) and the GMSS at 21.9 (3.8) months. Gross motor delay was defined as AIMS < 5th percentile and GMSS as < 4 (-2SD). Predictions using multiple logistic regressions were expressed as Odds Ratios (OR) and 95% Confidence Interval (CI). Of children, 100/250 (40%) had AIMS < 5th predicting GMSS < 4 (n = 43); sensitivity, specificity, positive, and negative predictive values were 88%, 71%, 40%, and 97%. Hospitalization days were independently associated with AIMS < 5th, OR 1.02 (95% CI 1.007, 1.032; p = 0.005). Excluding hospital days, ventilation days independently predicted AIMS < 5th, OR 1.08 (95% CI 1.038, 1.125, p < 0.001. Gross motor delay determine by AIMS scores of < 5th percentile occurred in 40% of survivors with good prediction of continued delay. Delay determined by AIMS was predicted by longer hospitalization and ventilation; further investigations about the causes are required. AIMS results provide opportunity for early motor intervention.

OBJECTIVES: The objectives of this study were to determine prevalence estimates of cerebral palsy (CP) among 5-year-old children in northern Alberta; to provide congenital, gestational age- and birth weight-specific, and postneonatal CP rates; and to describe motor subtypes and function. METHODS: This population-based prevalence estimate study, part of the Canadian Cerebral Palsy Registry, reports confirmed CP diagnoses at age 5 years made by pediatric rehabilitation and child neurology specialists. Prevalence rates with 95% confidence intervals (CIs) used Alberta government denominators of same-age children and live births. RESULTS: The Northern Alberta CP rate (birth years, 2008-2010) for 173 5-year-old children is 2.22 (95% CI 2.12, 2.32) per 1000 5-year-old children. The congenital CP rate is 1.99 (95% CI, 1.89-2.09) per 1000 live births; unilateral congenital CP, 1.0 (95% CI, 0.64-1.36) per 1000 live births; and postneonatal CP, 0.12 (95% CI, 0.1-0.14) per 1000 live births. Gestational age-specific rates are similar: age <28 weeks, 27.2 (95% CI, 23.05-31.35) and 28 to 31 weeks, 29.5 (95% CI, 25.78-33.22). Motor subtypes for 169 children (data missing, 4; male, 97; postnatal, 9) are: spastic, 148 (87.6%) including 31 (20.9%) with diplegia, 10 (6.8%) triplegia, 33 (22.2%) quadriplegia, 74 (50%) hemiplegia/monoplegia); and dyskinetic, 18 (10.6%) and ataxic, 3 (1.8%). A total of 107 (63.3%) ambulate without assistive devices and 111(65.7%) handle most objects with their hands independently. CONCLUSIONS: This is the fourth Canadian CP prevalence study; one from Quebec used a similar case ascertainment approach and two 1980s studies from Alberta and British Columbia used administrative databases. Northern Alberta CP rates are comparable with other developed countries. The hemiplegic subtype is the most common. Rates among preterm children have declined but are similar for the <28 and 28 to 31 gestation-week groups.

BACKGROUND AND OBJECTIVES: Little is known about chronic neuromotor disability (CND) including cerebral palsy and motor impairments after acquired brain injury in children surviving early complex cardiac surgery (CCS). We sought to determine the frequency and presentation of CND in this population while exploring potentially modifiable acute care predictors. METHODS: This prospective follow-up study included 549 children after CCS requiring cardiopulmonary bypass at ≤6 weeks of age. Groups included those with only 1 CCS, mostly biventricular CHD, and those with >1 CCS, predominantly single ventricle defects. At 4.5 years of age, 420 (94.6%) children received multidisciplinary assessment. Frequency of CND is given as percentage of assessed survivors. Predictors of CND were analyzed using multiple logistic regression analysis. RESULTS: CND occurred in 6% (95% confidence interval [CI] 3.7%-8.2%) of 4.5-year survivors; for 1 CCS, 4.2% (CI 2.3%-6.1%) and >1, 9.8% (CI 7%-12.6%). CND presentation showed: hemiparesis, 72%; spasticity, 80%; ambulation, 72%; intellectual disability, 44%; autism, 16%; epilepsy, 12%; permanent vision and hearing impairment, 12% and 8%, respectively. Overall, 32% of presumed causative events happened before first CCS. Independent odds ratio for CND are age (days) at first CCS, 1.08 (CI 1.04-1.12; P < .001); highest plasma lactate before first CCS (mmol/L), 1.13 (CI 1.03-1.23; P = 0.008); and >1 CCS, 3.57 (CI 1.48-8.9; P = .005). CONCLUSIONS: CND is not uncommon among CCS survivors. The frequency of associated disabilities characterized in this study informs pediatricians caring for this vulnerable population. Shortening the waiting period and reducing preoperative plasma lactate levels at first CCS may assist in reducing the frequency of CND.

For children with hemiplegic cerebral palsy, bimanual abilities are central to independent function. Over the last decade, considerable attention has been given to 2 forms of extended practice therapy for the upper limb, constraint-induced movement therapy and intensive bimanual training. This article reviews the varying nature of these 2 approaches and the existing scientific rationale supporting them. Comparisons between these 2 intensive upper extremity training approaches indicate similar improvements in unimanual capacity and bimanual performance outcomes; however, when considering participant and caregiver goal achievement, evidence favors a bimanual approach. Careful selection of either therapy for this population requires consideration of individual and contextual factors in relation to treatment goals. The key ingredients and dose responses remain unknown. Treatment intensity, intrinsic motivation, and individualization of treatment are hypothesized as requisite in either approach.
