Aim This paper reports the second phase of a study to extend the Melbourne Assessment for use with children with neurological impairment aged 2 to 4years. The aim was to establish if (1) children's scores on the Modified Melbourne Assessment (MMA) and the Quality of Upper Extremity Skills Test (QUEST) showed a moderate to high, positive relation, (2) children had comparable behaviours for task and time demands on both tools, and (3) scores on the MMA could discriminate between children with mild, moderate, and severe levels of upper limb impairment. Method An observational study of 30 children (19 males, 11 females) with neurological impairment aged 2 to 4years. Twenty-four children had spasticity (20 with a unilateral and four with a bilateral impairment) and two children presented with athetosis, two with ataxia, and two with hypotonia. Results A high, positive relation was found between children's scores on the MMA and the QUEST (ρ=0.90; p=0.001). The clinical use of the MMA was comparable to the QUEST. MMA scores were able to discriminate between children's levels of upper limb impairment as determined by clinicians' ratings (F 2,27=67.76, p=0.001). Interpretation These findings suggest the MMA can be clinically useful for children as young as 2.5years and has the advantage of being valid for use with older children. Scores from the tool can also provide therapists with a quantitative means of consistently reporting level of upper limb impairment. © The Authors.

Millions of Europeans still suffer the consequences of neurological disease, but the number of new drugs coming to market continues to fall. Reasons for the failure of stroke drug efficacy to translate from animals to clinical trials is probably best studied, but the problem is widespread. The economic and social costs of translational failure are substantial; a new approach to translational medicine is required. We propose the development of a capacity for multi-centre animal studies to address issues of limited validity; poor generalisability; and inadequate sample size. This will include central randomisation, outcome adjudication, and monitoring of laboratory practice; planned heterogeneity between sites to increase generalisability; and the capacity quickly to deliver large studies. Our data will be more reliable, reducing the need for further animal studies; and because clinical trials will be founded on better evidence the risk to participants will be lower. This idea has been broadly welcomed, and the next stage is to establish a framework within which this may be achieved. Our objective is to engage with all partners to build consensus around the feasibility, structure, composition and operation of multi-centre consortia. Issues include the role of industry and regulators; whether the capacity to deliver such studies exists; the statistical analysis to be used; and ethical, legal and governance issues. This consensus will be achieved through a series of themed meetings involving the applicants and others; the development of a detailed plan for such a consortium; and the validation of that plan with a specially constituted Scientific Advisory Board. We will then seek funding for the delivery of multi-centre animal studies based on this plan to allow its delivery. The applicants bring together substantial relevant expertise. This is a high-risk project, but the potential research, economic and health gains both in Europe and beyond are huge.

Background: Stroke patients are more likely to make a good recovery if they receive care in a well-organised stroke unit. However, there are uncertainties about how best to provide such care. We studied 2 key aspects of early stroke unit care: early active mobilisation (EM) and automated monitoring (AM) for physiological complications such as hypoxia. Methods: This was an observer-blinded, factorial (2 × 2) pilot randomised controlled trial recruiting stroke patients within 36 h of symptom onset. The patients were randomised to 1 of 4 nurse-led treatment protocols: (a) standard stroke unit care, (b) EM, (c) AM or (d) combined EM and AM. The primary outcome was the Rankin score at 3 months. We also report the data on feasibility and safety. Results: We randomised 32 patients (mean age = 65 years; mean baseline modified NIH score = 6). On unadjusted comparisons, the EM patients were significantly (p < 0.05) more likely to mobilise very early (within 1 h of randomisation) and to achieve walking by day 5 and were less likely to develop complications of immobility. The AM group was significantly (p < 0.05) more likely to have pre-defined physiological complication events detected. All these associations remained, but were less statistically significant, after correcting for age, baseline NIH score and co-interventions. There were no significant safety concerns. Discussion: We have demonstrated the feasibility of implementing EM and AM for physiological complications in a randomised controlled trial. Larger trials are warranted to determine whether these interventions have clinical benefits. Copyright © 2010 S. Karger AG, Basel.

The consortium led by UKER and EuroHYP, the European Stroke Research Network for Hypothermia, proposes a large, multicentre clinical trial which will assess mild hypothermia as a novel treatment for ischemic stroke. Stroke is the second cause of death world-wide and the second cause of lost disability-adjusted life years in high-income countries. Stroke incidence rises exponentially with age, so its social and economic burden will grow with the ageing of the European population. Current treatment options for the 80 to 85% of all strokes due to cerebral ischaemia - around. 900,000 events in Europe every year, or one every 40 seconds - are extremely limited. Systematic review of experimental studies suggests that hypothermia is the most promising intervention identified to date. Therapeutic cooling is effective in reducing ischaemic brain injury following cardiac arrest, and hypothermia is therefore considered by experts the most promising treatment for patients with acute ischaemic stroke, next to reperfusion strategies. The EuroHYP-1 trial is a pan-European, open, randomised, phase III clinical trial which will assess the benefit or harm of therapeutic cooling in 1500 awake adult patients with acute ischaemic stroke. In addition to efficacy and safety, the economic impact of therapeutic hypothermia will be assessed, along with several sub-studies involving imaging, ultrasound, and biomarker methods. The investigators involved in the EuroHYP-1 consortium are leading European experts in statistical design and analysis, therapeutic hypothermia, imaging, health economics, ultrasound, biomarkers, and trial execution (implementation and monitoring). Moreover in addition to these academic experts the consortium also involves European patient and family advocacy groups and small and medium-size enterprises, and the joint endeavours of this extended team will ensure the successful enrolment of patients at eighty hospitals across 25 countries in Europe.

Background and Purpose-Cognitive function is often ignored in stroke research trials. The brief Montreal Cognitive Assessment (MoCA) may be sensitive to stroke-related cognitive deficits. Methods-We evaluated the feasibility of administering the MoCA at 3 months in a large stroke trial (A Very Early Rehabilitation Trial [AVERT]). Results-Data (blinded to intervention group) are presented for 294 patients with mean age of 70.6 years (SD, 12.8); 220 (75%) completed the MoCA, 54 (18%) had missing data, and 20 (7%) had died. Of those surviving to 3 months, the MoCA was completed by 87% with mild stroke, 79% with moderate stroke, and 67% with severe stroke on admission. Mean MoCA score was 21.1 (SD 7.5) out of 30; only 78 of 220 (35%) patients attained the "normal" cutoff (26). Conclusions-The MoCA is a feasible global cognitive screening tool in stroke trials. © 2011 American Heart Association. All rights reserved.
