The re-education of upper limb movement post stroke using iterative learning control mediated by electrical stimulation

An inability to perform tasks involving reaching is a common problem following stroke. Evidence supports the use of robotic therapy and electrical stimulation (ES) to reduce upper limb impairments following stroke, but current systems may not encourage maximal voluntary contribution from the participant. This study developed and tested iterative learning control (ILC) algorithms mediated by ES, using a purpose designed robotic workstation, for upper limb rehabilitation post stroke. Surface electromyography (EMG) which may be related to impaired performance and function was used to investigate seven shoulder and elbow muscle activation patterns in eight neurologically intact and five chronic stroke participants during nine tracking tasks. The participants’ forearm was supported using a hinged arm-holder, which constrained their hand to move in a two dimensional horizontal plane.Outcome measures taken prior to and after an intervention consisted of the Fugl-Meyer Assessment (FMA) and the Action Research Arm Test (ARAT), isometric force and error tracking. The intervention for stroke participants consisted of eighteen sessions in which a similar range of tracking tasks were performed with the addition of responsive electrical stimulation to their triceps muscle. A question set was developed to understand participants’ perceptions of the ILC system. Statistically significant improvements were measured (p?0.05) in: FMA motor score, unassisted tracking, and in isometric force. Statistically significant differences in muscle activation patterns were observed between stroke and neurologically intact participants for timing, amplitude and coactivation patterns. After the intervention significant changes were observed in many of these towards neurologically intact ranges. The robot–assisted therapy was well accepted and tolerated by the stroke participants. This study has demonstrated the feasibility of using ILC mediated by ES for upper limb stroke rehabilitation in the treatment of stroke patients with upper limb hemiplegia

An exploration of stakeholders’ perceptions of the barriers to clinical use of Assistive Technologies in services for upper-limb stroke rehabilitation

Introduction Half of all patients commencing stroke rehabilitation have marked impairment of the hemiplegic arm, with only 14% regaining useful function. Assistive technologies (ATs) have been developed and evaluated yet currently reach only a fraction of patients. The NIHR funded a five year research programme to generate understanding necessary to develop cost-effective stroke services in upper-limb rehabilitation. This stage aims to understand the potential advantages and disadvantages to the clinical use of ATs, and the needs and priorities of stakeholders. Method Participants include people with a stroke (n=40), their carers (n=20), health care professionals (n= 40), budget holders (n=15) and service commissioners (n=15). An interactive exhibition was held at the University of Southampton in October 2009 where stakeholders tested a range of ATs. Focus groups with each stakeholder group will be conducted within three months of the exhibition to discuss personal involvement in AT use, and positive and negative views on the AT presented. Results Results will be categorised in terms of barriers and facilitators to the use of upper-limb technologies addressing issues such as user comfort and acceptability, cost-benefit, evidence of effect and funding provision. Conclusion Getting research implemented in practice is challenging. This novel approach explores the barriers to using new technologies from the perspective of all key stakeholders. These findings will be combined with those of a national survey, and systematic review to inform a clinical trial resulting in a recommended care pathway for upper-limb rehabilitation

Systematic review and evidence appraisal of objectively assessed longitudinal changes in moderate-to-vigorous physical activity among children and adolescents (2-18 years old)

The aim of this study was to systematically review accelerometer based longitudinal studies which have quantified year to year changes in moderate-to-vigorous physical activity (MVPA) among the general paediatric population in the absence of any intervention

A Systematic Review of International Clinical Guidelines for Rehabilitation of People With Neurological Conditions: What Recommendations Are Made for Upper Limb Assessment?

Conclusions: We present a comprehensive, critical, and original summary of current recommendations. Defining a core set of measures and agreed protocols requires international consensus between experts representing the diverse and multi-disciplinary field of neurorehabilitation including clinical researchers and practitioners, rehabilitation technology researchers, and commercial developers. Current lack of guidance may hold-back progress in understanding function and recovery. Together with a Delphi consensus study and an overview of systematic reviews of outcome measures it will contribute to the development of international guidelines for upper limb assessment in neurological conditions.This review formed part of the COST Action TD 1006A European Network on Robotics for Neurorehabilitation. It was an interdisciplinary EU-funded research network concentrating on the coordination of European research in the area of rehabilitation robotics

Longitudinal changes in moderate-to-vigorous-intensity physical activity in children and adolescents: a systematic review and meta-analysis

Moderate‐to‐vigorous‐intensity physical activity (MVPA) is important for childhood obesity prevention and treatment, yet declines with age. Timing and magnitude of the decline in MVPA in children and adolescents are unclear but important for informing effective obesity intervention development. This systematic review aimed to determine and compare the year‐to‐year changes in MVPA among children and adolescents. Longitudinal studies were identified by searching 10 relevant databases up to December 2018. Studies were eligible for inclusion if they reported accelerometer‐assessed MVPA (min day−1) separately for boys and girls and had follow‐up duration of at least 1 year. After screening 9,232 studies, 52 were included representing 22,091 aged 3 to 18 year olds (boys=8,857; girls=13,234). Pooled‐analysis of the relative change in MVPA per year showed a decline of −3.4% (95% CI, −5.9 to −0.9) in boys and −5.3% (95% CI, −7.6 to −3.1) in girls, across all age groups. There were notable declines in MVPA at age 9 for both boys (−7.8%, 95% CI, −11.2 to −4.4) and girls (−10.2%, 95% CI, −14.2 to −6.3). The relative decline in MVPA affects both sexes from an early age; however, it is greater among girls. Interventions to promote MVPA should start before adolescence

Religion between State and Society

In contrast to mainstream historiography, secularisation was not a distinct process in nineteenth-century Europe, since the century was a period of religious revival. In the late nineteenth century, in spite of weakening church attendance and rising agnosticism brought on by urbanisation and migration, religion remained attractive for the middle class and social movements related to church membership emerged in politics. In this chapter the diversity of religion in Europe is treated. The author distinguishes between hierarchical and nonhierarchical types of Christian churches, and between four religious regions in Europe. This situation had effects on the relationship between state and religion

The effect of a home-based strength training program on type 2 diabetes risk in obese Latino boys

This paper is designed to determine the effects of a home-based strength training (HBST) intervention on insulin sensitivity (SI), compensatory acute insulin response and β-cell function, body composition measures, and maximum strength in obese Latino boys. A total of 26 obese Latino males aged between 14 and 18 years were randomized to either a twice-weekly (n=15) or a control group (C; n=15) for 16 weeks. HBST for 16 weeks, composed of two 1-h sessions per week. Outcome measures were assessed pre-and post-intervention/control condition and included SI, acute insulin response to glucose (AIR) and disposition index (DI), fasting glucose, 2-h glucose, body composition using waist-hip circumferences, body mass index (BMI), dual energy X-ray absorptiometry (DEXA) scan, blood pressure, and strength by 1-repetition maximum. A repeated measures GLM was used to assess differences in changes in outcome measures, between the C and the HBST groups. There were no significant overall intervention effects on any of the outcome variables (p<0.05). These results suggest that an HBST does not improve SI, maximal strength or decrease adiposity in obese Latino boys
