Nombres retratados. Historias dibujadas transfronterizas y transgeneracionales
Authors: Peña-Sánchez Noemi , Noguera Ricardi Rita
Published: April 2020

Apresentamos uma experiência artística desenvolvida com estudantes da Universidade de La Laguna em Tenerife (Espanha) e com meninas e meninos do Mid-Peninsula Boys & Girls Club em San Mateo, Califórnia (EUA). O interesse comum dos educadores era promover experiências culturalmente diversas no ensino da arte e envolver os contextos educacionais em que estávamos. Buscamos gerar experiências vitais por meio do ensino da arte, nas quais a identidade aparece como protagonista. Nomes retratados é um projeto transfronteiriço que envolve os participantes desses territórios com quem iniciamos uma comunicação baseada em criações artísticas que retratam nomes de pessoas desconhecidas. Se planeja a partir de uma série de encontros nos quais imaginamos uma aparência através de um nome, nomes que transitam aqui e lá. Cada diálogo visual desperta pensamentos, estimula a imaginação e alimenta a curiosidade de saber com quem nos comunicamos. Todas essas criações geram conversas que supõem um grupo de pequenas histórias, as quais, em seu conjunto, constituem, sem querer, uma verdadeira história.

Being cool or being good: researching mobile phones in Mozambique
Authors: Archambault Julie Soleil
Published: April 2020

Drawing on my fieldwork experience in Inhambane, southern Mozambique, where I conducted research on mobile phone use amongst youth, my paper tackles issues of acceptance and rejection. As I sought to gain acceptance amongst youth I found myself participating in various controversial and, at times, dangerous activities that made me the victim of intense gossip and outright rejection by some. The fact that I came to the field accompanied by my husband and daughter only made matters worse. In this paper, I present the challenges of “being cool”, while also “being good”, and the repercussions of my research choices on my social standing. I then discuss how, instead of compromising my research, this predicament had a positive outcome by revealing social dynamics that might otherwise have remained hidden, namely the importance of concealment and the ambiguous role mobile phones play in deceit.
Conflict and Reproductive Health in Urban Chiapas: Disappearing the Partera Empίrica
Authors: Murray de Lopez Jenna
Published: April 2020

This article looks at how the unresolved internal armed conflict in Chiapas intersects with existing structural violence manifest in the everyday forms of harassment, abuse, and violence, all of them shaping the fabric of women’s existence. This includes both the way they are treated by professionals in the healthcare system and unintended consequences of health policy and initiatives to reduce maternal mortality. I argue it is useful to examine these two factors jointly in order to identify a relationship between armed conflict in rural areas and its indirect costs on the nearby urban environment. I will focus on one main point of discussion: the way a health-policy emphasis on decreasing maternal mortality (as an indirect consequence of the armed conflict) is changing how and where urban women give birth, effectively disappearing the role of the urban ‘partera empírica’.
Avaliação da proficiência de professores de matemática em equações literais: um estudo de caso comparativo com proposta de manual didático
Authors: Araújo Evando Santos , Da Silva Filho Manoel Pereira
Published: April 2020

Equações Literais são expressões matemáticas que possuem, além da variável em questão, coeficientes representados de forma genérica por letras. Essas equações recebem destaque na busca por uma aprendizagem de matemática mais significativa, uma vez que podem ser utilizadas para modelar e interpretar inúmeros fenômenos em diversas áreas do conhecimento. Neste trabalho, avaliou-se a proficiência de professores de matemática em equações literais a partir das respostas dadas por eles a questionários que discutiam aspectos da formação acadêmica, da prática docente e do conhecimento técnico sobre o assunto. Os dados coletados foram analisados via modelo de Rasch Dicotômico, antes e depois da disponibilização de um manual didático aos participantes da pesquisa, produzido para sanar possíveis dificuldades com o tema. Os resultados iniciais se mostraram bastante preocupantes uma vez que, para a grande maioria dos participantes, o modelo retornou que a habilidade desses profissionais era insuficiente para que respondessem positivamente aos itens sobre o conhecimento do conteúdo. Esse resultado foi relacionado com a formação inicial e o exercício docente. Por outro lado, verificou-se que após a capacitação com o manual didático, o nível de conhecimento desses indivíduos aumentou significativamente nos quesitos avaliados inicialmente, com consequente aumento das probabilidades de sucesso com o tema.

ANÁLISE DE PROBLEMAS DO CAMPO CONCEITUAL MULTIPLICATIVO PRESENTES EM LIVROS DIDÁTICOS DE 5º ANO OFERTADOS PELO PNLD
Authors: Peron Luciana Del Castanhel , Nogueira Clélia Maria Ignatius , Rezende Veridiana
Published: April 2020

Este artigo apresenta uma investigação a respeito de problemas do Campo Conceitual Multiplicativo em dois livros didáticos do 5º ano do Ensino Fundamental, utilizados pela rede municipal de ensino de Foz do Iguaçu – Paraná, nos anos de 2016–2018 e de 2019– 2022. As análises foram sustentadas na Teoria dos Campos Conceituais, particularmente no que diz respeito à classificação dos problemas propostos nas obras, relacionados ao Campo Conceitual Multiplicativo. Os resultados apontam que, em sua maioria, os problemas do Campo Conceitual Multiplicativo presentes em ambas as obras referem-se à classe Proporção Simples. Já a classe de problemas que aparece com menos frequência nas obras é a de Produto Cartesiano. A classe Comparação Multiplicativa aparece apenas na obra Projeto Coopera (2014), a classe Função Bilinear apenas na obra Ápis-Matemática (2017) e a classe de Proporção Múltipla não é mencionada em ambas as obras.  Por essa razão, entendemos que existe a necessidade de planejamento, pelos professores, de atividades complementares às propostas pelas obras para a efetivação do trabalho com as estruturas multiplicativas em sala de aula. No que diz respeito às duas obras adotadas pela rede municipal de Foz do Iguaçu, nos anos de 2016 e 2019, podemos inferir que a diversidade de problemas do Campo Conceitual Multiplicativo não foi um dos critérios adotados para a escolha das obras. Além disso, podemos afirmar que a diversidade dessas classes de problemas também não foi um dos fatores contemplados no processo PNLD 2019, no que se refere ao edital de proposição de obras ao Ministério de Educação, às habilidades e competências presentes na BNCC e a avaliação realizada nas obras.

Демографические и технологические изменения такие, как старение населения и цифровизация, оказывают глобальное влияние на социальную сферу и рынок труда. Трансформация традиционной модели занятости с расширением неформальных трудовых отношений и трудовой мобильности, а также сокращением налоговых (страховых) поступлений от трудовых контрактов определяют соответствующую трансформацию социального обеспечения и его администрирования. В тоже время электронные и интернет-технологии заменяют предоставление социальных услуг в бумажном формате с присутствием получателей таких услуг. Как ответ на эти вызовы для администрирования социального обеспечения внедряются новые подходы, что происходит неравномерно в разных странах. Какие тенденции в администрировании социального обеспечения, «лучшие практики» станут ведущими в будущем? Какой опыт может рассматриваться как пример? Этим вопросам посвящен данный обзор, который может быть интересен для понимания перспектив социального обеспечения и его администрирования.
Problématiser et traiter la question de la chute du Mur trente ans après auprès d’un public étudiant en France : enjeux et méthodes
Authors: Goudin-Steinmann Elisa
Published: April 2020

Trente ans après la chute du Mur, comment trouver un angle adéquat pour véhiculer en France les représentations les plus justes possibles sur ce qu’a été la RDA ? Comment problématiser cette question pour l’aborder de façon plus originale que la seule étude de l’appareil de répression ? Comment sortir du récit de la Erfolgsgeschichte de la République fédérale et de la Misserfolgsgeschichte de la RDA qui en serait le pendant ? Nous proposons plusieurs pistes pour ouvrir ce débat, sous la forme de trois idées directrices : mettre l’accent sur les acteurs, sur la notion de troisième voie, et utiliser les résultats de la recherche récente sur la RDA, car on n’écrit pas aujourd’hui l’histoire de la RDA comme dans les années 1990.

Authors: Zaitsev S.V. , Visalova A.E. , Lyamasova V.M. , Izmailov A.E.
Published: April 2020

Subject. The article considers theoretical aspects of nominal, accrued, real, and disposable wages and savings in the Astrakhan Oblast in various areas of economic activity.
Objectives. The study aims to review movements in wages and their level, develop methods for assessing wages, calculate and analyze real wages and savings in the Astrakhan Oblast.
Methods. The study draws on the analysis of data on the number of employees and their wages and salaries in the Astrakhan Oblast, which are provided by the Office for National Statistics, and the calculation of indicators based on these data.
Results. We analyzed trends in wage increase and the number of employed population in the Astrakhan Oblast. The paper systematizes theoretical aspects of wage assessment, presents calculated indicators of real wages and savings of the employed population. The indicators of savings are divided into groups reflecting the level of household wealth. We provide diagrams illustrating the demand for labor in the Astrakhan Oblast. The findings may be useful for the analysis of living standard in the said area, its socio-economic level. They are also helpful for formulating directions for the region's development.
Conclusions. Despite the growth of nominal wages in most spheres of economic activity, more than half of the population of the Astrakhan Oblast do not have incomes to satisfy all their social and spiritual needs, since a large portion of income goes to the minimum needs of subsistence, payment for utilities, cellular communication services and internet, and transport.

Os resultados apontam para a necessidade de aprofundamento das pesquisas, em particular para a classe de trabalhadores reincidentes devido a seu comportamento divergente dos padrões esperados.
A long term baseline and variability of natural radionuclides in groundwater at the Vaalputs low-level radioactive waste disposal facility, Namaqualand, South Africa: regional implications
Authors: Pretorius H.C.F. , Tredoux M. , Andreoli M.A.G. , Vermeulen P.D.
Published: April 2020

Vaalputs is the only South African nuclear waste disposal facility; it is licensed to dispose of low and intermediate level radioactive waste. Possible disposal of long-lived waste, potentially including spent fuel rods, prompted a study to establish a baseline of naturally-occurring radionuclides from the U and Th decay chains in the groundwater of Vaalputs. This baseline was created by investigating a dataset containing 25 years of analyses of the groundwater at the Vaalputs site. The behaviour over time, of 23 radionuclides in groundwater samples from 13 annually and three quarterly sampled boreholes, was evaluated and integrated in order to establish changing trends in the activities of radionuclides, the relative contributions of individual radionuclides to total radiation levels and how these were influenced by groundwater conditions. 238U levels showed a natural anomaly in the near-field of the disposal site that was attributed to the underlying basement rocks (granites) which are anomalously enriched in U. A set of duplicate samples from 2009 determined that the activity ratio of 234U/238U in the groundwater of Vaalputs is 4.1; this is ascribed to more rapid leaching of 234U relative to 238U, because of increased crystal structural damage around sites surrounding 234U atoms. High levels of 226Ra, unsupported by 238U, were found in groundwater from boreholes on the western side of the property: this groundwater yielded low values for 234U/238U, lower pH and stronger oxidizing conditions than groundwater from the rest of the area. The absence of overlying sedimentary rocks, which tend to ameliorate the effects of high radiation from granites by absorption, is suggested as the reason for the different geochemical conditions of the groundwater from boreholes in the west. This suggestion may apply to those boreholes elsewhere in Namaqualand with low published concentrations of 238U, but exceptionally high levels of α -and β-emitters. 232Th and its daughter radionuclides yielded radiation levels far below the guideline of 1 Bq.L-1 specified by the World Health Organization; this result is in line with the known low mobility of Th in groundwater systems.
Reduction of term in scientific theory
Authors: Surovyagin Dmitriy Pavlovich
Published: April 2020

The subject of this research is the concept of reduction in logics and methodology of science. On the one hand, reduction is understood as a relation between the term and its defining expression within the scientific theory; while on the other – it represents the relation between two theories. Since the extension of theory is possible through introduction to its vocabulary of new terms by means of nominal definitions, the reduction represents an inverse operation – removing the terms from the vocabulary of the theory. At the same time, the theory itself is defined in accordance with the theoretical-multiple approach as a class of sentences closed in relation to derivability. The scientific novelty consists in examination of semantic and epistemological aspects of the formal definition of reduction. Particularly, the explication of reduction relation between two theories leans in the concept of functional equivalence of the theories. It is established that the list of basic terms of the theory can be set only conventionally. All terms introduces by the means of nominal definitions turn out to be reducible. Therefore, a distinctive feature of theoretical terms is the possibility of its reduction.

Authors: Avila Lucas Coelho de , Neto Romeu e Silva
Published: April 2020

O mundo moderno é marcado por rápidas e crescentes transformações tecnológicas, econômicas e sociais, portanto o empreendedorismo e a inovação desempenham uma grande relevância nesse contexto. Todavia, como o ambiente é caracterizado por muita incerteza e dinamismo é necessário que existam instituições orientadas a fornecer o apoio e o suporte que novos negócios necessitam em seus estágios iniciais, como por exemplo, os Centros de Inovação, Parques Tecnológicos ou incubadoras de empresas. Sendo assim, o presente trabalho apresenta o objetivo de avaliar como a produção científica brasileira vem abordando a relação entre o estabelecimento de Centros de Inovação, ou outros ambientes orientados ao mesmo fim, no tocante ao desenvolvimento de empreendedorismo e inovação. Para tal, primeiramente foi realizado um estudo bibliométrico onde foi possível analisar o comportamento do Brasil quanto a publicações relacionadas a essa temática, em comparação com os demais países do mundo; além disso, foram destacados os periódicos responsáveis pela maior quantidade de trabalhos nacionais e internacionais, as principais afiliações brasileiras e as tendências de evolução dessas pesquisas no Brasil. Verificou-se que o Brasil ocupa o quarto lugar dentre os países com vinte trabalhos publicados. Após isso, foi proposto um método para classificar e selecionar os trabalhos brasileiros encontrados, com base nas informações coletadas no levantamento bibliométrico, e depois foi realizada uma revisão sistemática dos artigos selecionados. Por fim, foi possível concluir que o trabalho contribui com informações relevantes para orientar novos pesquisadores a respeito de como se encontra essa temática no meio acadêmico, em especial nas pesquisas brasileiras.

Conclui-se que a execução do exercício de tríceps na polia precedido ao exercício de supino resultou no estresse funcional somente na 1ª série e, que a presença da fadiga do músculo peitoral apresentada nas séries subsequentes não impactou no aspecto funcional do exercício de supino.
General Screening of Surface Alloys for Catalysis
Authors: Montemore Matthew , Nwaokorie Chukwudi F. , Kayode Gbolade O.
Published: April 2020

Intensive research in catalysis has resulted in design parameters for many important catalytic reactions; however, designing new catalysts remains difficult, partly due to the time and expense needed to screen a large number of potential catalytic surfaces. Here, we create a general, efficient model that can be used to screen surface alloys for many reactions without any quantum-based calculations. This model allows the prediction of the adsorption energies of a variety of species (explicitly shown for C, N, O, OH, H, S, K, F) on metal alloy surfaces that include combinations of nearly all of the d-block metals. We find that a few simple structural features, chosen using data-driven techniques and physical understanding, can be used to predict electronic structure properties. These electronic structure properties are then used to predict adsorption energies, which are in turn used to predict catalytic performance. This framework is interpretable and gives insight into how underlying structural features affect adsorption and catalytic performance. We apply the model to screen more than 107 unique surface sites on approximately 106 unique surfaces for 7 important reactions. We identify novel surfaces with high predicted catalytic performance, and demonstrate challenges and opportunities in catalyst development using surface alloys. This work shows the utility of a general, reusable model that can be applied in new contexts without requiring new data to be generated.

Authors: Skrypnyk Tetiana , Biryukova Karina
Published: April 2020

In the article, the authors analyze ways to increase the professional competence of teachers of multidisciplinary IEP teams. This allows the conclusion that that the use of coaching is appropriate for mastering support specialists with inclusive technologies, as well as the ability to work in a team interaction mode. Despite the obvious advantages of teamwork, in Ukraine this format of work is still not mastered in an inclusive educational environment. In the article the authors present the structure of the training program based on the team management model for significant achievements (R. Hackman). We conducted a training program for 10 IEP teams, aimed at increasing the level of team interaction and inclusive competence of specialists. Formative influence was done directly during the professional activity of teachers and was accompanied by prolonged expert coaching.
In their study, the authors applied a special design scheme for teamwork. This scheme was concretized in the fact that the participants of the IEP teams used the experience gained in the training sessions in the practice of their professional activity, critically comprehended and analyzed their new experience, sought to comprehend the factors of both success and failure. Together with the coordinator and experts, all participants of the IEP teams developed rules for the team, established feedback, sought to influence the focus on mastering the modern approaches of the inclusive process at the level of the entire educational institution. In turn, this maintained the necessary level of motivation and joint intentions to introduce a competently constructed educational environment.
To assess the state of inclusive competence formation before and after the training program, we used teacher self-assessment method «Professional Development Tool for Improving the Quality of Practice in primary school». As a result, all teachers have achieved a significant increase in the effectiveness of interdisciplinary support for children with special needs, which have reflected in the positive changes that have occurred in teachers at the professional, interpersonal and personal levels.
Sistemas de Classificação Intuitiva como Possibilidade para o Ensino de Diversidade Animal no Contexto da Educação do Campo
Authors: Cardoso de Sousa Diany Kelly , Alexandre Freixo Alessandra
Published: April 2020

O presente artigo apresenta e avalia uma possibilidade para o ensino sobre diversidade animal a partir de uma investigação sobre as classificações intuitivas de estudantes de uma escola de ensino fundamental no contexto do campo. A pesquisa aconteceu em uma Escola Família Agrícola no Semiárido da Bahia, por meio de oficinas das quais participaram 44 estudantes das turmas de 7º e 9º anos do ensino fundamental, no ano de 2017. Pautada nos aspectos metodológicos da pesquisa-ação, os encontros ocorreram em três momentos distintos, nos quais realizou-se um levantamento dos conhecimentos etnobiológicos dos estudantes sobre a fauna, por meio de desenhos e descrições. Os estudantes realizaram classificações intuitivas com os animais citados e, por fim, abriu-se espaço para um possível diálogo de saberes, estimulando os estudantes a perceber semelhanças ou diferenças entre os modos de agrupar os animais, sejam suas classificações intuitivas, seja a classificação filogenética. Os dados obtidos passaram por análise de conteúdo. Os resultados apontam que algumas das categorias utilizadas pelos estudantes para agrupar os animais, como “animais da caatinga”, “animais nojentos”, “animais de produção”, expressam o valor simbólico e cultural que os estudantes apresentam sobre animais que pertencem ou não ao seu ambiente e convívio. A abordagem utilizada na presente pesquisa mostra grande potencial enquanto estratégia que permite a criação de um espaço em que os estudantes possam interagir e participar, promovendo o diálogo entre professor/aluno/conteúdo.

A better understanding of the transmission of SARS-CoV-2, its sequelae, and how its mortality can be curtailed is a priority. While predictions that much of the population will get infected before the epidemic abates due to a depletion of the susceptible population would seem robust, predictions of the morbidity and mortality burden that this will generate and the impact of interventions are still somewhat speculative. Interventions are mostly aimed at increasing social distancing, e.g. by closing schools and shops, and banning social gatherings, often amounting to a complete lockdown of societies. While such measures are probably successful in reducing contacts among the young and healthy, they conspicuously fail to curb transmission to the old and vulnerable dependent on care who are increasingly the victims of this pandemic. We discuss the critical role of nosocomial transmission in the COVID-19 pandemic.
Is the “respiratory stimulant, Acetazolamide” add-on therapy suitable to relieve mild respiratory insufficiency in stable COVID-19 out/inpatients?

Severe acute respiratory syndrome coronavirus 2 (SARS- CoV-2) and its related disease, COVID-19 is terribly spreading to 202 countries, areas or territories. Till March 29th, 2020 the values of confirmed cases and total deaths were more than 575,000 and ~ 26,500. Due to epithelial injury, as a critical event both in early stages of the disease and specifically in the development of acute respiratory distress syndrome (ARDS), patients encounter rapid vasoconstriction in the pulmonary circulation, followed by ventilation/perfusion mismatch. Acetazolamide-medaited carbonic anhydrase (CA) inhibition may attenuate the effects of hyperventilation-induced respiratory alkalosis. The evidences on chronic obstructive pulmonary disease (COPD) and acute mountain sickness (AMS) support our proposition that low doses of acetazolamide appear to stimulate ventilation in stable patients with COVID-19.

Influence of specimen diameter size on the deformation behavior and short-term strength range of an aluminum alloy
Authors: Seisenbacher Benjamin , Klösch Richard , Winter Gerhard , Grün Florian
Published: April 2020

Components often manifest varied local behavior due to their manufacturing process. In order to be able to determine local material behavior in the best possible way, it is necessary to take specimens from the area under investigation. Due to constant developments in efficiency and lightweight construction, it is difficult to produce standard-compliant specimens from the examined area in a component. For this reason, specimens with smaller dimensions are often taken. Through the investigation of the influence of size in the area of high-cycle fatigue, it is well known that the size of a test specimen influences its lifespan. Not so much is known about the influence of specimen size on the behavior of material in the field of low-cycle fatigue (LCF). In this work, tensile, LCF and thermomechanical fatigue tests are performed using AlCu4PbMgMn with varied specimen geometries, the smallest test diameter being 3 mm, the largest 7.5 mm. The results of the tensile test show that the mean values of tensile strength for both diameters is within one percent. At LCF load and thermomechanical load, there are no or only slight deviations in deformation behavior. The low cycle fatigue behavior at RT is identical for both diameters. However, the results show that stress-strain behavior is the same for both test diameters, and fatigue behavior is the same, except in tests with high strain amplitudes and temperature.

In this study, multi-layered composite pipes with varied orientation angles and subjected to internal pressure were investigated by using the 3-D finite element method (FEM) and through experimental tests. The composite pipes were made of E-glass and T300/934 carbon fiber. The studies were carried out experimentally, analytically and numerically. The T300/934 carbon fiber reinforced composite pipes and E-glass reinforced composite pipes were given numerical model codes via ANSYS 14.5 software. These models were then compared with analytical results in the literature and with the experimental results. Finite element analyses (FEA) were carried out to predict failure loads. Each layer of the composite pipes was numerically examined from various orientation angles. Hoop and shear stress wereobtained numerically for each layer. Radial strain and radial stress were achieved in the radial direction of the composite pipes. Shear extension coupling was considered because the layup angles with + θ and - θ layers were in varied radii. Subsequently, the effects of the orientation angles were examined for all models. Moreover, it was found that an embedded adhesive joint is important for industrial applications.
Prescribing Patterns of Aminoglycoside Antibiotics in a Teaching Hospital in Sudan

Published: April 2020

Background: Aminoglycoside antimicrobials are widely used for the treatment of severe gram-negative
bacterial infections. Their inappropriate use may result in treatment failure, development of resistant
pathogens, and toxicity. Drug utilization evaluation of aminoglycosides can improve rational use.
Purpose: This study intended to assess the prescribing patterns and potential problems associated with
gentamicin and amikacin use.
Methods: This prospective observational study was conducted at Soba University Hospital, Khartoum,
Sudan. Patients’ demographics, clinical and prescription information were collected using a data collection
form. Laboratory data of patients were collected from the patients' files. Ideal body weight was calculated
to assess dose appropriateness, and adverse drug reactions were observed.
Results: A total of 200 patients were included in the present study, two-thirds of the patients were prescribed
gentamicin, while the remainder were given amikacin. Dosing was inappropriate in (60.6%) and (76.5%) of
patients on gentamicin and amikacin respectively. Conventional dosing was used more commonly (67%)
than extended dosing (33%). All indications for the use of these drugs were found to be appropriate. In
(72%) of cases, both gentamicin and amikacin were prescribed based on microbiological sensitivity testing.
Auditory function monitoring was only performed for neonates and infants. Nephrotoxicity was detected in
7 patients (9.3%), and ototoxicity in one patient (1.3%).
Conclusion: Although prescription and dosing based on ideal body weight and microbiological data were
reasonably common, higher compliance with recommended practice is needed in addition to therapeutic
drug monitoring in order to ensure safe and effective treatment, and reduced antibiotic resistance.
Physiotherapy Program for Managing Adhesive Capsulitis in Patients with Diabetes: A Protocol for a Pilot Randomized Trial
Authors: Alsubheen Sanaa , MacDermid Joy C. , Faber Kenneth J. , Furtado Rochelle , Alsubheen Sanaa , Overend Tom J.
Published: April 2020

Background: Adhesive capsulitis (AC) occurs five times more often in people with diabetes and leads to
prolonged disability. Exercises and joint mobilization are usually used to manage AC. However, the
recovery is slow and often incomplete. Aerobic exercises improve hyperglycemia and insulin sensitivity.
Currently, no research has formally assessed the benefits of incorporating an aerobic training program into
the treatment plan of AC in patients with diabetes. This single blind pilot randomized trial will compare the
preliminary effect of a regular physiotherapy program (PT), to a regular PT program combined with a
progressive walking program (PT+) in patients with and without diabetes who have AC.
Methods: Patients (n= 40) will be recruited from St. Joseph's HealthCare Centre and associated primary
care practices. Patients will be randomly assigned into either the regular PT program or regular PT combined
with a progressive walking program. Patients will be referred to physical therapy facilities and the
intervention will be chosen by the treating physical therapist. In the PT+ group, patients will be asked to
perform free walking at their own pace for 30-45 minutes, five days per week, for six consecutive weeks.
The primary outcome will be testing the functional performance of the shoulder using the Functional
Impairment Test- Hand and Neck/ Shoulder/Arm (FIT-HaNSA) test. Secondary outcomes will include
shoulder pain and function using the Shoulder Pain and Disability Index (SPADI) questionnaire; shoulder
range of motion in flexion, abduction, and external rotation; muscles strength of shoulder flexors and
abductors; and physical activity level using an accelerometer and the Rapid Assessment of Physical Activity
(RAPA) questionnaire. The primary outcome will be evaluated at baseline and after six weeks. Secondary
outcomes will be evaluated at baseline, and after three, six and 12 weeks from enrolment.
Discussion: The novel approach taken in this pilot trial will establish the preliminary effect of a regular PT
program combined with a progressive walking program and will evaluate a study design prior to the
performance of a full-scale research project that may lead to better outcomes for managing adhesive
capsulitis in people with diabetes.
