Objective: To examine whether elbow coordination training can improve elbow coordination in cerebral palsy and whether any benefit carries over to upper limb activity.

Methods: A case series A–B–C multiple baseline study was carried out. Two weeks of no intervention (A) was followed by 2 weeks of computerised tracking (B), which was followed by 2 weeks of no intervention (C). Six children (age range 7–12 years) with hemiplegic cerebral palsy (Level I–III of the Manual Ability Classification System) participated. Coordination training consisted of 10 × 1-min trials of computerised tracking each session for 10 sessions over a 2-week period. Coordination was measured as tracking performance using a different target from the training target. Upper limb activity was measured using the 9-Hole Peg Test. Data were analysed using the 2-SD band method.

Results: None of the participants appeared to improve tracking performance or 9-Hole Peg Test (9HPT) scores (p > 0.05) after the 2 weeks of intervention. On withdrawal of the intervention, visual analysis showed that tracking performance and 9HPT scores remained at the same level as the intervention phase.

Conclusions: Ten minutes of computerised elbow tracking daily for 10 sessions did not improve coordination in six children with cerebral palsy.

Objectives: Anosognosia for motor impairment is a complex syndrome that can manifest itself under different forms, guiding patients’ behavior and task decisions. However, current diagnostic tools tend to evaluate only more explicit aspects of anosognosia (asking the patients about their motor abilities) and fail to address more subtle features of awareness. We have developed a new assessment measure, the ECT (Errand Choice Test), where patients are asked to judge task difficulty rather than estimate their own impairment. Methods: We assessed awareness in a group of 73 unilateral left- and right-brain damaged (30 LBD and 43 RBD, respectively) patients by means of the VATAm, which explicitly requires them to evaluate their own motor abilities, and the ECT. A control group of 65 healthy volunteers was asked to perform the ECT under two conditions: Current condition (i.e., using both hands) and Simulated conditions (i.e., simulating hemiplegia). Results: A total of 27% of the patients showed different performance on the VATAm and ECT, 21% of the patients showing lack of awareness only on VATAm and 6% only on ECT. Moreover, despite the ECT identified a higher frequency of anosognosia after RBD (33.3%) than LBD (27.6%), this hemispheric asymmetry was not significant. Remarkably, anosognosic patients performed very similarly to controls in the “current condition”, suggesting that anosognosic patients’ ability to perceive the complexity of each task per se is not altered. Conclusion: Different methods may be able to tackle different aspects of awareness and the ECT proved to be able to detect less evident forms of awareness. (JINS, 2018, 24, 45–56)

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.

We report the case of a 33-year-old woman who developed a dense hemiplegia immediately after an uncomplicated general anaesthetic for diagnostic laparoscopy. She had a history of recurrent hemiplegic migraine with a strong family history. Her migraine was normally associated with visual disturbances and a unilateral headache followed by a left-sided weakness such that she was unable to walk. Symptoms would last up to 24 h. Her post-operative state was atypical of her normal migraine, in that she had no headache or visual disturbance and initially all four limbs were affected.

A representative sample of 55 mainstreamed 9–10-year-olds with hemiplegia were compared with all classmates on sociometric measures of popularity and friendship, and with 55 matched controls on measures of victimisation. Children with hemiplegia were more rejected and less popular, had fewer friends, and were more often victimised; they were not more likely to be bullies themselves. These differences were not fully accounted for by group differences in teacher-estimated IQ and behaviour. Possible explanations range from neurologically determined deficits in mentalising skills to peer prejudices about children with disabilities. The development of appropriate intervention strategies should be a high priority, particularly since peer problems not only result in current distress but also predict psychosocial problems in the future.
