Towards real-time profiling of sprints using wearable pressure sensors

On-body sensor systems for sport are challenging since the sensors must be lightweight and small to avoid discomfort, and yet robust and highly accurate to withstand and capture the fast movements associated with sport. In this work, we detail our experience of building such an on-body system for track athletes. The paper describes the design, implementation and deployment of an on-body sensor system for sprint training sessions. We autonomously profile sprints to derive quantitative metrics to improve training sessions. Inexpensive Force Sensitive Resistors (FSRs) are used to capture foot events that are subsequently analysed and presented back to the coach. We show how to identify periods of sprinting from the FSR data and how to compute metrics such as ground contact time. We evaluate our system using force plates and show that millisecond-level accuracy is achievable when estimating contact times. © 2012 Elsevier B.V. All rights reserved.

Development of a Complex Intervention for Secondary Prevention of Coronary Heart Disease in Primary Care Using the UK Medical Research Council Framework

Objective: To apply the UK Medical Research Council (MRC) framework for development and evaluation of trials of complex interventions to a primary healthcare intervention to promote secondary prevention of coronary heart disease. Study Design: Case report of intervention development. Methods: First, literature relating to secondary prevention and lifestyle change was reviewed. Second, a preliminary intervention was modeled, based on literature findings and focus group interviews with patients (n = 23) and staff (n = 29) from 4 general practices. Participants’ experiences of and attitudes toward key intervention components were explored. Third, the preliminary intervention was pilot-tested in 4 general practices. After delivery of the pilot intervention, practitioners evaluated the training sessions, and qualitative data relating to experiences of the intervention were collected using semistructured interviews with staff (n = 10) and patient focus groups (n = 17). Results: Literature review identified 3 intervention components: a structured recall system, practitioner training, and patient information. Initial qualitative data identified variations in recall system design, training requirements (medication prescribing, facilitating behavior change), and information appropriate to the prospective study participants. Identifying detailed structures within intervention components clarified how the intervention could be tailored to individual practice, practitioner, and patient needs while preserving the theoretical functions of the components. Findings from the pilot phase informed further modeling of the intervention, reducing administrative time, increasing practical content of training, and omitting unhelpful patient information. Conclusion: Application of the MRC framework helped to determine the feasibility and development of a complex intervention for primary care research.

The SPHERE Study: Secondary prevention of heart disease in general practice: protocol of a randomised controlled trial of tailored practice and patient care plans with parallel qualitative, economic and policy analyses. [ISRCTN24081411]

Background: The aim of the SPHERE study is to design, implement and evaluate tailored practice and personal care plans to improve the process of care and objective clinical outcomes for patients with established coronary heart disease (CHD) in general practice across two different health systems on the island of Ireland.CHD is a common cause of death and a significant cause of morbidity in Ireland. Secondary prevention has been recommended as a key strategy for reducing levels of CHD mortality and general practice has been highlighted as an ideal setting for secondary prevention initiatives. Current indications suggest that there is considerable room for improvement in the provision of secondary prevention for patients with established heart disease on the island of Ireland. The review literature recommends structured programmes with continued support and follow-up of patients; the provision of training, tailored to practice needs of access to evidence of effectiveness of secondary prevention; structured recall programmes that also take account of individual practice needs; and patient-centred consultations accompanied by attention to disease management guidelines.

Methods: SPHERE is a cluster randomised controlled trial, with practice-level randomisation to intervention and control groups, recruiting 960 patients from 48 practices in three study centres (Belfast, Dublin and Galway). Primary outcomes are blood pressure, total cholesterol, physical and mental health status (SF-12) and hospital re-admissions. The intervention takes place over two years and data is collected at baseline, one-year and two-year follow-up. Data is obtained from medical charts, consultations with practitioners, and patient postal questionnaires. The SPHERE intervention involves the implementation of a structured systematic programme of care for patients with CHD attending general practice. It is a multi-faceted intervention that has been developed to respond to barriers and solutions to optimal secondary prevention identified in preliminary qualitative research with practitioners and patients. General practitioners and practice nurses attend training sessions in facilitating behaviour change and medication prescribing guidelines for secondary prevention of CHD. Patients are invited to attend regular four-monthly consultations over two years, during which targets and goals for secondary prevention are set and reviewed. The analysis will be strengthened by economic, policy and qualitative components.

Monitoring treatment fidelity in a randomised controlled trial of a complex intervention.

Aim. This paper is a report of a study to describe how treatment fidelity is being enhanced and monitored, using a model from the National Institutes of Health Behavior Change Consortium. Background. The objective of treatment fidelity is to minimize errors in interpreting research trial outcomes, and to ascribe those outcomes directly to the intervention at hand. Treatment fidelity procedures are included in trials of complex interventions to account for inferences made from study outcomes. Monitoring treatment fidelity can help improve study design, maximize reliability of results, increase statistical power, determine whether theory-based interventions are responsible for observed changes, and inform the research dissemination process. Methods. Treatment fidelity recommendations from the Behavior Change Consortium were applied to the SPHERE study (Secondary Prevention of Heart DiseasE in GeneRal PracticE), a randomized controlled trial of a complex intervention. Procedures to enhance and monitor intervention implementation included standardizing training sessions, observing intervention consultations, structuring patient recall systems, and using written practice and patient care plans. The research nurse plays an important role in monitoring intervention implementation. Findings. Several methods of applying treatment fidelity procedures to monitoring interventions are possible. The procedure used may be determined by availability of appropriate personnel, fiscal constraints, or time limits. Complex interventions are not straightforward and necessitate a monitoring process at trial stage. Conclusion. The Behavior Change Consortium’s model of treatment fidelity is useful for structuring a system to monitor the implementation of a complex intervention, and helps to increase the reliability and validity of evaluation findings.

Efficacy of a powered wheelchair simulator for school aged children: A randomised controlled trial.

Purpose: To determine the efficacy of a custom made wheelchair simulation in training children to use a powered wheelchair (PWC). Design: Randomised controlled trial employing the 4C/ID-model of learning. Twenty-eight typically developing children (13M, 15F; mean age 6 years, SD 6 months) were assessed on their operation of a PWC using a functional evaluation rating scale. Participants were randomly assigned to intervention (8x 30minute training sessions using a joystick operated wheelchair simulation) or control conditions (no task), and were re-assessed on their PWC use following the intervention phase. Additional data from the simulation on completion times, errors and total scores were recorded for the intervention group. Results: Analysis of variance showed a main effect of time, with planned comparisons revealing a statistically significant change in PWC use for the intervention (p = 0.022) but not the control condition. Whilst the intervention group showed greater improvement than the controls this did not reach statistical significance. Multiple regression analyses showed that gender was predictive of pre-test (p = 0.005) functional ability. Implications: A simulated wheelchair task appears to be effective in helping children learn to operate a PWC. Greater attention should be given to female learners who underperformed when compared to their male counterparts. This low cost intervention could be easily employed at home to reduce PWC training times in children with motor disorders.

A Pilot Evaluation of the Palliative Performance Scale in Long Term Care: Tips for Success

Aims: Palliative care in long-term care (LTC) homes is an area of growing concern. Little work has been done to explore innovative ways to identify and care for residents who become palliative. The purpose of this intervention study was to evaluate the implementation of the Palliative Performance Scale (PPS) in LTC. Specifically we explored staff perceptions about implementing the PPS and how it cued staff to initiate palliative care discussion with residents and family when a resident’s health declined.

Methods: This study utilized a qualitative descriptive design that included data from four separate sources: journals of three ‘champions’ who were responsible for leading the implementation of the PPS; staff evaluations of three educational training sessions; minutes from meetings; and 11 interviews from key staff who were involved in the implementation process. Data were analyzed using thematic content analysis.

Results: Staff generally felt positively about using the PPS in LTC and stated that it increased awareness of palliative care and helped identify those residents who were nearing the end of life. There were some barriers to implementing it, such as staff resistance and lack of time to complete it. The importance of having a designated ‘champion’ and effective interdisciplinary communication in addition to widespread training, were identified as successful strategies to facilitate the implementation process.

Conclusion: These study findings support the use of the PPS in LTC and offer some perspective about ways to implement it successfully. Future work is needed to evaluate the PPS in LTC using more rigorous designs.

Six-year follow-up of the SPHERE RCT: secondary prevention of heart disease in general practice.

Objective: To determine the long-term effectiveness of a complex intervention in primary care aimed at improving outcomes for patients with coronary heart disease.

Design: A 6-year follow-up of a cluster randomised controlled trial, which found after 18 months that both total and cardiovascular hospital admissions were significantly reduced in intervention practices (8% absolute reduction).

Setting: 48 general practices in the Republic of Ireland and Northern Ireland.

Participants: 903 patients with established coronary heart disease at baseline in the original trial.

Intervention: The original intervention consisted of tailored practice and patient plans; training sessions for practitioners in medication prescribing and behavioural change; and regular patient recall system. Control practices provided usual care. Following the intervention period, all supports from the research team to intervention practices ceased.

Outcome measures: Primary outcome: hospital admissions, all cause and cardiovascular; secondary outcomes: mortality; blood pressure and cholesterol control.

Results: At 6-year follow-up, data were collected from practice records of 696 patients (77%). For those who had died, we censored their data at the point of death and cause of death was established. There were no significant differences between the intervention and control practices in either total (OR 0.83 (95% CI 0.54 to 1.28)) or cardiovascular hospital admissions (OR 0.91 (95% CI 0.49 to 1.65)). We confirmed mortality status of 886 of the original 903 patients (98%). There were no significant differences in mortality (15% in intervention and 16% in control) or in the proportions of patients above target control for systolic blood pressure or total cholesterol.

Conclusions: Initial significant differences in the numbers of total and cardiovascular hospital admissions were not maintained at 6 years and no differences were found in mortality or blood pressure and cholesterol control. Policymakers need to continue to assess the effectiveness of previously efficacious programmes.

O currículo das ciências físicas e naturais na perspetiva docente: saberes profissionais e possibilidades de ação

O atual contexto social de aceleração exponencial, resultante de alterações políticas, económicas e do acesso imediato a um extenso conjunto de informações e a um manancial de desenvolvimentos científicos e tecnológicos, cujas implicações são imprevisíveis e transversais a diferentes setores, está em dissonância com as características do modelo escolar dominante e a naturalizada ‘gramática da escola’ (Formosinho & Machado, 2008; Nóvoa, 2009a; Tyack & Tobin, 1994). Este desfasamento, amplificado em países com sistemas de ensino de matriz centralizada, resvala entre uma ação docente acrítica e executora e, em oposição, uma ação docente de natureza profissional, caracterizada por um alinhamento entre o desenvolvimento profissional e a afirmação da especificidade do conhecimento profissional docente, enquanto saber que se constrói na interação com os outros, com o próprio, nos e sobre os contextos de prática. A implementação do processo de reorganização curricular do ensino básico (Decreto-Lei n.º 6/2001, de 18 de janeiro) redefiniu o currículo nacional segundo duas perspetivas: a nacional e a local, veiculando uma conceção curricular flexível e emancipatória, isto é, uma proposta curricular que confere aos professores autonomia no desenvolvimento e gestão do currículo, instigando-os à realização de práticas curriculares com intencionalidade pedagógica estratégica. Neste sentido, a pretensão desta investigação situou-se ao nível da problematização de saberes profissionais e da concetualização de algumas possibilidades de ação tangenciais à capacidade de autotransformação de cada profissional docente e da escola. As opções metodológicas consideradas visaram, sobretudo, compreender quais os possíveis conhecimentos profissionais mobilizados por professores de Ciências Físicas e Naturais, em particular ao nível do desenvolvimento e gestão do currículo desta área curricular. Assim, perspetivado sob a forma de questão enquadradora, o problema que esteve na génese desta investigação assume a seguinte formulação: Que conhecimento mobilizam professores do ensino básico no desenvolvimento e na gestão do currículo das Ciências Físicas e Naturais? De que forma e com que ações poderá ser potenciado esse conhecimento nos processos de ensino e aprendizagem? O estudo empírico que sustentou este projeto de investigação organizou-se em dois momentos distintos. O primeiro, de natureza predominantemente quantitativa e dimensão de análise extensiva, envolveu a administração de um inquérito por questionário a professores de Ciências Físicas e Naturais que, no ano letivo de 2006/2007, se encontravam a lecionar em escolas públicas com 2.º e 3.º ciclos afetas à Direção Regional de Educação do Norte e ao, anteriormente, designado Centro de Área Educativa de Aveiro. Com um enfoque preponderantemente qualitativo, o segundo momento do estudo decorreu ao longo do ano letivo de 2007/2008 num agrupamento de escolas da região norte do país e consistiu na realização de entrevistas a oito professores de Ciências Físicas e Naturais, à coordenadora do departamento de Matemática e Ciências Experimentais e aos presidentes do Conselho Pedagógico e do Conselho Executivo. Ao longo do ano letivo, os professores de Ciências Físicas e Naturais desenvolveram, igualmente, um percurso formativo cuja ênfase se situava ao nível da adequação do desenvolvimento e gestão do currículo desta área disciplinar. As técnicas de tratamento de dados privilegiadas foram a análise estatística e a análise de conteúdo. Os resultados deste estudo apontam para a prevalência de uma ação docente desprovida de intencionalidades pedagógica e curricular ou de integração na construção do corpo geral do saber, designadamente ao nível dos processos de desenvolvimento e gestão do currículo. Não obstante alguma familiarização com conceitos inerentes à dimensão do conhecimento do currículo, os indicadores de reapropriação ao nível da ação docente foram escassos, denunciando a presença de constrangimentos no domínio teórico das orientações curriculares nacionais e locais, bem como no desenvolvimento de práticas curriculares articuladas e estrategicamente definidas. Por outro lado, o predomínio de uma ação docente tendencialmente acrítica, de matriz executora, associada ao cumprimento de normativos legais e de rotinas e burocracias instituídas, indiciou fragilidades ao nível do conhecimento profissional configurado como mobilização complexa, organizada e coerente de conhecimentos científicos, curriculares, pedagógicos e metodológicos, em função da especificidade de cada situação educativa e cuja finalidade é a otimização da aprendizagem do aluno. O percurso formativo afigurou-se como um espaço de partilha e de reflexão colegial, propício ao desenvolvimento de ações que se inserem numa perspetiva de ‘action learning’, possibilitando a reflexão e a aprendizagem através de ações empreendidas em função de práticas educativas. As possibilidades de ação remetem para a integração da formação contínua em contexto, com intencionalidades pedagógicas e curriculares estrategicamente definidas, e a problematização da formação inicial e contínua dos professores, envolvendo as perspetivas de diferentes atores educativos e de investigadores educacionais.

Construção de conhecimento em ambientes virtuais : influência das relações interpessoais

A presente investigação foi conduzida no ambiente virtual imersivo 3D Second Life®, com o suporte de ferramentas Web 2.0 como complemento a aulas presenciais - numa lógica de sala de aula estendida. Teve como pressuposto que a socialização é um fator-chave para as aprendizagens colaborativas e para a construção de conhecimento. O estudo tem por objetivo identificar as variáveis que poderão influenciar a partilha de conhecimento em contextos de aprendizagem com recurso a ambientes virtuais; com a finalidade de contribuir para a melhoria das situações de aprendizagem com recurso a ferramentas online. Esta investigação é de carácter exploratório e enquadra-se no campo dos estudos fenomenológicos. O estudo foi implementado, em duas fases, com quatro turmas de ensino superior, duas turmas diurnas (regime geral) e duas turmas de ensino noturno (regime de maiores de 23). Todas seguindo o mesmo curso e a mesma unidade curricular. Concluímos que nos espaços virtuais os estudantes tendem a sentir-se mais confiantes, abertos, participativos, criativos, compreensivos e parecem participar nas sessões de formação online porque estão, de facto, interessados em aprender. Por outro lado, a possibilidade de providenciar sessões de tutória online permite chegar a um maior número de estudantes. Estas sessões online podem ser estabelecidas numa hora e local (virtual) livre de restrições e que pode ser adaptado, permitindo uma participação mais efetiva por parte dos estudantes. Assim, e com base nas observações retiradas do estudo implementado, pode ainda referir-se que os contrastes de comportamento verificados entre os alunos do regime diurno e do regime noturno, no que concerne ao empenhamento com as ferramentas online, parecem ser em função do nível de maturidade, do nível de independência enquanto alunos, da motivação intrínseca.

European information users: topics from a comparative analysis within the European Union

Purpose – The aim of this article is to present some results from research undertaken into the information behaviour of European Documentation Centre (EDC) users. It will reflect on the practices of a group of 234 users of 55 EDCs covering 21 Member States of the European Union (EU), used to access European information. Design/methodology/approach – In order to collect the data presented here, five questionnaires were sent to users in all the EDCs in Finland, Ireland, Hungary and Portugal. In the remaining EU countries, five questionnaires were sent to two EDCs chosen at random. The questionnaires were sent by post, following telephone contact with the EDC managers. Findings – Factors determining access to information on the European Union and the frequency of this access are identified. The information providers most commonly used to access European information and the information sources considered the most reliable by respondents will also be analysed. Another area of analysis concerns the factors cited by respondents as facilitating access to information on Europe or, conversely, making it more difficult to access. Parallel to this, the aspects of accessing information on EU that are valued most by users will also be assessed. Research limitations/implications – Questionnaires had to be used, as the intention was to cover a very extensive geographical area. However, in opting for closed questions, it is acknowledged that standard responses have been obtained with no scope for capturing the individual circumstances of each respondent, thus making a qualitative approach difficult. Practical implications – The results provide an overall picture of certain aspects of the information behaviour of EDC users. They may serve as a starting point for planning training sessions designed to develop the skills required to search, access, evaluate and apply European information within an academic context. From a broader perspective, they also constitute factors which the European Commission should take into consideration when formulating its information and communication policy. Originality/value – This is the first piece of academic research into the EDCs and their users, which aimed to cover all Members State of the EU.
