ABSTRACT
BACKGROUND: After a stroke, most patients often suffer reduced walking ability and balance. Restoring walking ability and improving balance are major goals of stroke rehabilitation. Treadmills are often used in clinical setups to achieve these goals. Adding dimensions to the visual feedback in addition to the mirror for real-time frontal view is proven to enhance the gait. It is, therefore, important to design additional real-time visual feedback in treadmill training, in particular for the sagittal view involved side. OBJECTIVE: The objective of this study is to test if the real-time sagittal visual feedback during treadmill training is superior to the conventional mirror feedback treadmill training program of equivalent intensity in improving walking speed and balance after stroke. METHODS/DESIGN: The RE-VISIT trial (Real-time Visual feedback after Stroke in Treadmill training) is registered in the Clinical Trial Registry of India (CTRI/2023/10/058299). In this two-arm randomized control trial, which will be a single-blinded study, 42 eligible stroke survivors undergoing rehabilitation will be randomly allocated (1:1 ratio) to either real-time visual sagittal feedback along with front mirror (experimental) group or only front mirror treadmill training (control) group, all the participants will receive 15 sessions of treadmill training for up to 15 min at a safe self-selected speed over 5-6 weeks. The RE-VISIT (experimental) group will receive real-time, visual sagittal view feedback of the involved lower limb trajectory along with the routine front mirror view during treadmill training and will be asked to modify their gait pattern. The control group will receive treadmill walking training only with the routine front mirror view feedback. Clinical and gait assessments will be conducted at the baseline, immediately following the final session of training, and at the 9th week during follow-up. The outcome measures of interest are walking speed (primary) and balance (secondary), which will be measured prior to baseline, post 15 sessions of training, and at the 9th week following training. DISCUSSION: This REVISIT trial will provide insight and contribute to the existing innovation and modifications of incorporating realtime visual feedback during treadmill training in post-stroke gait rehabilitation. The findings will help the better designing of a gait rehabilitation program with a treadmill for post-stroke subjects to improve walking speed, and balance for those who have greater difficulties in community ambulation. We anticipate that those in the REVISIT training will demonstrate improved walking ability.
CONTEXTO: Após o acidente vascular cerebral, a maioria dos pacientes frequentemente sofre redução da capacidade de caminhar e do equilíbrio. Restaurar a capacidade de caminhar e melhorar o equilíbrio são os principais objetivos da reabilitação do AVC. As esteiras são frequentemente usadas em ambientes clínicos para atingir esses objetivos. Está comprovado que adicionar dimensões ao feedback visual, além do espelho para visão frontal em tempo real, melhora a marcha. É, portanto, importante projetar feedbacks visuais adicionais em tempo real no treinamento em esteira, em particular para o lado envolvido na visão sagital. OBJETIVO: O objetivo deste estudo é testar se o feedback visual sagital em tempo real durante o treinamento em esteira é superior ao programa de treinamento em esteira com feedback de espelho convencional de intensidade equivalente na melhoria da velocidade de caminhada e equilíbrio após acidente vascular cerebral. MÉTODOS/ DESENHO: O ensaio RE-VISIT (feedback visual em tempo real após acidente vascular cerebral no treinamento em esteira) está registrado no Registro de Ensaios Clínicos da Índia (CTRI/2023/10/058299). Neste ensaio de controle randomizado de dois braços, que será um estudo cego, 42 sobreviventes de AVC elegíveis em reabilitação serão alocados aleatoriamente (proporção de 1:1) para feedback sagital visual em tempo real junto com grupo de espelho frontal (experimental) ou apenas Grupo de treinamento em esteira com espelho frontal (controle), todos os participantes receberão 15 sessões de treinamento em esteira por até 15 minutos em uma velocidade segura e autosselecionada durante 5-6 semanas. O grupo RE-VISIT (experimental) receberá feedback visual em tempo real da visão sagital da trajetória dos membros inferiores envolvidos, juntamente com a visão rotineira do espelho frontal durante o treinamento em esteira e será solicitado a modificar seu padrão de marcha. O grupo de controle receberá treinamento de caminhada em esteira apenas com o feedback rotineiro da visão do espelho frontal. Avaliações clínicas e de marcha serão realizadas no início do estudo, imediatamente após a sessão final de treinamento e na 9ª semana durante o acompanhamento. As medidas de resultados de interesse são a velocidade de caminhada (primária) e o equilíbrio (secundário), que serão medidos antes da linha de base, após a 15ª sessão de treinamento e na 9ª semana após o treinamento. DISCUSSÃO: este ensaio REVISIT fornecerá insights e contribuirá para a inovação e modificações existentes na incorporação de feedbacks visuais em tempo real durante o treinamento em esteira na reabilitação da marcha pós-AVC. As descobertas ajudarão no melhor desenho de um programa de reabilitação da marcha com esteira para indivíduos pós-AVC para melhorar a velocidade de caminhada e o equilíbrio para aqueles que têm maiores dificuldades na deambulação comunitária. Prevemos que aqueles no treinamento REVISIT demonstrarão melhor capacidade de caminhada.

ABSTRACT
RESUMO Introdução A percepção auditiva da voz e sua produção envolvem o feedback auditivo, as pistas cinestésicas e o sistema de feedforward, os quais produzem efeitos distintos para a voz. Os efeitos Lombard, Sidetone e o Pitch-Shift-Reflex são os mais estudados. O mapeamento de experimentos científicos sobre as modificações do feedback auditivo para o controle motor da voz possibilita examinar a literatura existente sobre o fenômeno e pode contribuir para o treinamento ou terapias da voz. Objetivo Mapear os experimentos e resultados das pesquisas com manipulação do feedback auditivo para o controle motor da voz de indivíduos adultos. Método Revisão de escopo seguindo o Checklist Preferred Reporting Items for Systematic reviews and Meta-Analyses extension (PRISMA-ScR) para responder à pergunta: "Quais os métodos de investigação e principais achados das pesquisas sobre a manipulação do feedback auditivo no automonitoramento da voz de indivíduos adultos?". O protocolo de busca foi baseado na estratégia mnemônica População, Conceito e Contexto (PCC). A população são os indivíduos adultos; o conceito é a manipulação do feedback auditivo e o contexto é o controle motor da voz. Os artigos foram pesquisados nas bases de dados: BVS/ Biblioteca Virtual em Saúde, MEDLINE/Medical Literature Analysis and Retrieval Sistem on-line, COCHRANE, CINAHL/Cumulative Index to Nursing and Allied Health Literature, SCOPUS e WEB OF SCIENCE. Resultados Foram encontrados 60 artigos, sendo 19 da temática do Efeito Lombard, 25 do efeito Pitch-shift-reflex, 12 do efeito Sidetone e quatro sobre o efeito Sidetone/Lombard. Os estudos são concordantes que a inserção de um ruído que mascara o feedback auditivo provoca um aumento na intensidade de fala do indivíduo e que a amplificação do feedback auditivo promove a redução do nível de pressão sonora na produção da voz. Observa-se uma resposta reflexa à mudança de tom no feedback auditivo, porém, com características individuais em cada estudo. Conclusão O material e método dos experimentos são distintos, não há padronizações nas tarefas, as amostras são variadas, muitas vezes reduzidas. A diversidade metodológica dificulta a generalização dos resultados. Os principais achados das pesquisas a respeito o feedback auditivo sobre o controle motor da voz confirmam que, na supressão do feedback auditivo, o indivíduo tende a aumentar a intensidade da voz. Na amplificação do feedback auditivo, o indivíduo diminui a intensidade e tem maior controle sobre a frequência fundamental e, nas manipulações da frequência, o indivíduo tende a corrigir a manipulação. Os poucos estudos com sujeitos disfônicos mostram que eles se comportam diferentemente dos não disfônicos.
ABSTRACT Introduction The auditory perception of voice and its production involve auditory feedback, kinesthetic cues and the feedforward system that produce different effects for the voice. The Lombard, Sidetone and Pitch-Shift-Reflex effects are the most studied. The mapping of scientific experiments on changes in auditory feedback for voice motor control makes it possible to examine the existing literature on the phenomenon and may contribute to voice training or therapies. Purpose To map experiments and research results with manipulation of auditory feedback for voice motor control in adults. Method Scope review following the Checklist Preferred Reporting Items for Systematic reviews and Meta-Analyses extension (PRISMA-ScR) to answer the question: "What are the investigation methods and main research findings on the manipulation of auditory feedback in voice self-monitoring of adults?". The search protocol was based on the Population, Concept, and Context (PCC) mnemonic strategy, in which the population is adult individuals, the concept is the manipulation of auditory feedback and the context is on motor voice control. Articles were searched in the databases: BVS/Virtual Health Library, MEDLINE/Medical Literature Analysis and Retrieval System online, COCHRANE, CINAHL/Cumulative Index to Nursing and Allied Health Literature, SCOPUS and WEB OF SCIENCE. Results 60 articles were found, 19 on the Lombard Effect, 25 on the Pitch-shift-reflex effect, 12 on the Sidetone effect and four on the Sidetone/Lombard effect. The studies are in agreement that the insertion of a noise that masks the auditory feedback causes an increase in the individual's speech intensity and that the amplification of the auditory feedback promotes the reduction of the sound pressure level in the voice production. A reflex response to the change in pitch is observed in the auditory feedback, however, with particular characteristics in each study. Conclusion The material and method of the experiments are different, there are no standardizations in the tasks, the samples are varied and often reduced. The methodological diversity makes it difficult to generalize the results. The main findings of research on auditory feedback on voice motor control confirm that in the suppression of auditory feedback, the individual tends to increase the intensity of the voice. In auditory feedback amplification, the individual decreases the intensity and has greater control over the fundamental frequency, and in frequency manipulations, the individual tends to correct the manipulation. The few studies with dysphonic individuals show that they behave differently from non-dysphonic individuals.
ABSTRACT
Los estudios en niños/as y adolescentes con Trastorno por Déficit de Atención e Hiperactividad (TDAH) suelen evidenciar dificultades en la toma de decisiones, vinculadas con comportamientos más riesgosos. El objetivo del presente estudio fue analizar y comparar el proceso de Toma de Decisiones Bajo Riesgo (TDBR) en niños/as y adolescentes con TDAH, considerando los tipos de retroalimentaciones utilizadas. Los tipos de retroalimentaciones se refieren al procesamiento de las consecuencias de las decisiones de los ensayos previos y a su influencia en las elecciones presentes y futuras. Se realizó un estudio descriptivo comparativo con un diseño ex post facto retrospectivo con dos grupos. La muestra estuvo compuesta por 100 niños/as y adolescentes de 8 a 15 años (68 niños y niñas de 8 a 11 años y 32 adolescentes de 12 a 16 años), divididos en grupo clínico y grupo control, pareados por sexo y edad. Para evaluar la TDBR se administró el Test de los Dados (The Game of Dice Task, GDT), la cual es una prueba informatizada en la que se deben tomar decisiones apostando para ganar puntos. Para analizar los tipos de retroalimentación se consideraron ocho tipos posibles. Los resultados evidenciaron un comportamiento con una tendencia a elegir opciones de riesgo en la población con TDAH, tanto en el tipo de elecciones realizadas como en la forma en que utilizan la retroalimentación al ganar o al perder, no vinculándose necesariamente con decisiones desfavorables. Estos hallazgos podrían contribuir al desarrollo de programas de intervención destinados a disminuir las dificultades en la toma de decisiones en personas con diagnóstico de TDAH.
Studies on children and adolescents with Attention Deficit Hyperactivity Disorder (ADHD) often show difficulties in decision-making, linked to riskier behaviors. The aim of the present study was to analyze and compare the process of Decision Making Under Risk (DMUR) in children and adolescents with ADHD considering the types of feedback used. Feedback types refer to processing the consequences of previous trial decisions and their influence on present and future choices. A comparative descriptive study was carried out with a retrospective ex post facto type design with two groups. The sample consisted of 100 boys, girls and adolescents from 8 to 15 years old, (68 boys and girls from 8 to 11 years old and 32 adolescents from 12 to 16 years old), divided into a clinical group and a control group paired by sex and age. To evaluate the DMUR, the Game of Dice Task (GDT) was administered, which is a computerized test in which betting decisions must be made to earn points. And to analyze the types of feedback, eight possible types were considered. The results showed a behavior with a tendency to choose risky options in the population with ADHD, both in the type of choices made and in the way, they use feedback when winning or losing, not necessarily linked to unfavorable decisions. These findings could contribute to the development of intervention programs aimed at reducing the difficulties in decision-making in people diagnosed with ADHD.
ABSTRACT
The objective is to present a daily attitudes and professionalism assessment instrument for medical students in theoretical-practical activities. The development of the instrument was based on the manuals of the program for student integration with the community, on the program's pedagogical project, and on the National Curricular Guidelines for Undergraduate Programs in Medicine, and was carried out by professors. These were consulted in weekly 50-minute meetings held between August and November 2016. At the end of the process, a version of the instrument was consolidated with five items and six descriptors to discriminate learning situations that enable competency-based assessment from the simplest to the most complex level. With the use of the instrument, points considered important in medical training in theoretical-practical activities cannot be overlooked (AU).

Tuberculosis is known as one of the long-standing and dominating health problems affecting people and the extent further escalates in a developing country like India. A pre-evaluated feedback structured questionnaire was validated and adopted to get their quantitative data from 424 respondents. In the present study urban respondents (60.8%) gave affirmative responses regarding awareness of TB, especially with mobile media as their major source of information, followed by information from healthcare workers. Rural respondents were less expressed and deficient on knowledge of TB transmission and preventive methods. Prevention practices toward TB are claimed to be high in urban population because 79.48% believed that early diagnosis, prompt treatment and avoiding poor hygiene and crowded environment are effective strategies to cease the transmission of TB. Effective preventive and informative strategies should be employed in rural border areas to make up for the knowledge gap found among rural and urban populations in this study.
ABSTRACT
Background: Proper understanding of concepts of physiology forms basis of good clinical practice. To make the lectures in physiology more interesting and understanding, one has to review the teaching methods at regular intervals. Aims and Objectives: This study is designed to get feedback regarding teaching methods in physiology from MBBS students of Government Medical College, Kozhikode, to make teaching more effective. Materials and Methods: Two hundred randomly selected students who successfully completed 1st-year MBBS are included in the study group. The standard questionnaire is shared to study group through Google forms and adequate time is given to record their responses. Descriptive statistics are used. Frequency is expressed in percentage. Results: Most of students prefer interactive teaching methodologies such as group discussion as their preferred mode of learning rather than conventional didactic lectures in whole batch. Students also like to have integration with other subjects and early clinical exposure to understand the concepts precisely. Conclusion: Teaching in small groups with proper integration and alignment with other subjects will make maximum results rather than the traditional teacher centered medical education. Periodic review of teaching methods is very much essential to make the subject more interesting.
ABSTRACT
Background: Competency-based medical education (CBME) curriculum has been implemented in India since 2019 with a goal to create an “Indian Medical Graduate” (IMG) possessing requisite knowledge, skills, attitudes, values, and responsiveness. Objectives: To explore teachers’ perceptions across India at medical colleges on the newly implemented competency-based medical education curriculum. Methods: This was a qualitative cross?sectional study conducted among teachers working at medical colleges across India, between February and April 2022 (n = 192). The data collection was done using Google forms online survey platform on teachers’ perception regarding CBME, its specific components, and perceived bottlenecks. We analyzed this qualitative data using manual, theoretical thematic content analysis following the steps endorsed in Braun and Clarke’s six-phase framework. Results: The majority of the teachers (64.1%) have positively responded to the CBME curriculum’s implementation. However, it came with a caution that the curriculum should continuously evolve and adapt to regional demands. The foundation course, early clinical exposure, and the family adoption program were the specific components of CBME curriculum over which the teachers raised concerns. The need for additional teachers in each department (department-specific teacher or faculty per hundred students ratio to be worked out) and the need for enabling faculty preparedness through adequate training was highlighted. Concerns were also raised regarding implementing CBME with teachers without a medical background (especially in preclinical departments). Conclusion: It is the need of the hour for the curriculum to incorporate a systematic feedback mechanism built into the system, though which such critical appraisals can be meaning collated and acted upon, to ultimately evolve, thereby creating an “Indian Medical Graduate” for the needs of todays’ society.
ABSTRACT
Background: Providing immediate feedback to students has shown improvement in students’ knowledge, understanding, and confidence as it helps in identifying lacunae and loopholes in learning process. Despite the usefulness of feedback, common complaint from students is that they usually do not receive feedback immediately in their learning process. We also face similar situation with our students in institute. The aim of this study was to find out effect of giving immediate feedback and explore the views of medical students on immediate feedback during formative assessment. Aims and Objectives: The aims of this study were to evaluate the effect of immediate feedback on the medical students’ learning in medical education. Materials and Methods: The study was conducted in Department of Physiology, GMERS Medical College, Valsad on 183 students of 1st MBBS after ethical approval. Two types of modules were prepared on using “Hot Potatoes” software version 6.3. Module-1: Test 1 without feedback: consist of 20 MCQs and Module-2: Test 2 with feedback: consist of 20 MCQs, provide immediate feedback for each option of MCQ. Two modules were given one by one on WhatsApp group on mobile phone. Reflection writing and feedback from students were taken after that. Results: The qualitative data collected provided important information about the immediate feedback. Feedback responses of students on the questionnaire were analyzed using Likert scale. The Likert scale values were in strongly agree/agree part for Module-2 (with feedback). The students believed that immediate feedback was very helpful in clearing concepts, finding out lacunae, improvement in confidence, and self-learning. An excellent way for self-assessment and improved their deeper understanding of content areas. The students enjoyed innovative way of learning compared to conventional learning. Conclusion: Immediate feedback using this type of feedback modules should be implemented to improve students’ knowledge, understanding, memory, and confidence and can be used as self-directed learning tool.
ABSTRACT
Background: Pharmacology, being both basic and applied science, is indeed the foundation of rational therapy. Pharmacology education needs constant reform and reorganization to review and adapt learning and teaching methods. It can be better achieved using student feedback. Aims and Objectives: The study was designed to obtain and evaluate the feedback of students on various teaching and evaluation methods in pharmacology. Materials and Methods: It is a cross-sectional study. A pre-tested questionnaire used for the purpose of this study. After obtaining permission from the Institutional Ethics Committee, a questionnaire was given to the students of Bachelor of Medicine and Bachelor of Surgery (MBBS), Bachelor of Dental Surgery, Bachelors in science (Nursing), and Allied Health Sciences (AHS) courses. Students who completed pharmacology as a part of their course curriculum were enrolled in the study. Results: A total of 273 students participants took part in our study. The most common age was 20 years (147 students, 53.8%), more females (153 students, 56%), and the majority of them were MBBS students (153 students, 56%). Most of the students found that knowledge of chemotherapy will be useful during the post-course internship (26.4%) and the knowledge of autocoids will be the least useful in clinical practice (1.1%). Students preferred more than studying method for pharmacology (37.4%). Conclusion: An effective teaching program is beneficial to comprehend pharmacology. Any effort at obtaining constant feedback from students makes our methodologies more relevant and interesting. Any worthwhile effort in this direction will lead to more rational prescribers and/or health-care professionals in the future.
ABSTRACT
Objective:To observe any effect of Yun shou tai chi training with visual feedback on the balance of persons who have survived a stroke.Methods:Fifty-six stroke survivors were randomly divided into an observation group and a control group, each of 28. Both groups were given routine balance function training, while the observation group was additionally given Yun shou tai chi training with visual feedback. Before and after the four weeks of training, the subjects′ balance and posture were evaluated using a Nomex visual feedback balance system. Lower limb strength was evaluated with a microFET2 portable muscle strength tester. The Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), 10-metre walk times (10MWTs) and the modified Barthel Index (MBI) were also applied.Results:After the training the average BBS, TUGT, 10MWT and MBI results of the observation group had improved significantly. Among the control group only TUGT times and MBI scores had improved significantly, but even then the average MBI score of the observation group was significantly higher. The training improved the strength of the trainees′ quadriceps femoris (QUA), tibialis anterior (TA) and gastrocnemius (GAS) on the hemiplegic side. Their hamstrings and GAS on the non-hemiplegic side were also significantly stronger, on average. The improvement in the QUA of the hemiplegic side in the observation group was significantly better than the control group′s average improvement. The path length (PL) and the covered area (CA) in the observation group had decreased significantly after the training, while among the controls only the CA had decreased significantly. The average PL in the observation group was therefore significantly shorter than in the control group.Conclusion:Yun shou tai chi training with visual feedback can promote the recovery of balance function after a stroke. Such training is worthy of clinical promotion and application.
ABSTRACT
Objective:To observe any effect of combining vibroacoustic therapy with audio-visual feedback on the swallowing and the emotional state of persons with a swallowing disorder after a brainstem stroke.Methods:Fifty brainstem stroke survivors with dysphagia were randomly divided into a control group and a combination group, each of 25. In addition to routine swallowing function training, the control group received additional direct feeding training, while the combination group was provided with vibroacoustic feeding training and swallowing stimulation from an animated audio-visual presentation. Before and after the treatment, the subjects′ swallowing function was quantified using the Standard Swallowing Assessment (SSA) scale and the Gugging swallowing screen (GUSS). The Positive and Negative Emotions Scale (PNAS) was used to quantify their emotional state.Results:After the treatment the average SSA scores of both groups had decreased significantly, while the average GUSS and PNAS scores had increased significantly. The average improvements in all three measures were significantly greater in the combination group than in the control group.Conclusion:In addition to routine swallowing function training, feeding training applying vibroacoustics and audio-visual stimulation can significantly improve the feeding function and emotional state of brainstem stroke survivors with dysphagia.
ABSTRACT
Objective:To study the effect of blood volume feedback control system on improving intradialytic-hypotension (IDH) in maintenance hemodialysis (MHD) patients.Methods:It was a prospective cohort study. Thirty MHD patients with recurrent IDH in the Dialysis Center of the First Affiliated Hospital of Zhejiang University School of Medicine from March 2021 to March 2022 were selected. A self-control study was conducted in MHD patients. The patients were treated with routine hemodialysis in both baseline phase (A1) and reversal phase (A2), while with hemodialysis under the blood volume feedback control system in intervention phase (B). Each phase lasted for 4 weeks (12 hemodialysis sessions). The average occurrences of IDH and IDH-related adverse events (IDH-RAE, stopping dehydration for more than 10 minutes or getting off the hemodialysis machine 10 minutes earlier due to IDH) of each patient between phase A1, B, and A2 were calculated and compared. In a total of 1 080 dialysis records, a logistic regression analysis model was established with age, sex and intervention as independent variables and with the occurrence of IDH-RAE as the outcome.Results:A total of 30 eligible patients were included in the study, including 14 males (46.7%) and 16 females (53.3%), aged 63.0 (56.5, 72.5) years old, with a median dialysis age of 84.0 (37.2, 120.0) months. The average times of IDH in 30 MHD patients decreased from 1.17 (0.83, 1.67) in stage A1 (before intervention) to 0.33 (0.25, 0.58) in stage B (after intervention) ( P<0.05). The frequency of IDH-RAE decreased significantly from 0.29 (0.19, 0.47) in stage A1 to 0.17 (0,0.25) in stage B ( P<0.05). Logistic regression analysis results indicated that the use of blood volume feedback control system reduced the risk of IDH-RAE by 53% ( OR=0.47, 95% CI 0.34-0.64, P<0.001). Conclusions:The application of blood volume feedback control system can effectively reduce the occurrences of IDH and the risk of IDH-RAE in MHD patients.
ABSTRACT
Objective:To explore the relationship between thyroid hormone sensitivity and obesity phenotype in people with normal thyroid function.Methods:In this retrospective study, 6155 euthyroid subjects who underwent a health check-up in the First Hospital of China Medical University between January 2017 and December 2018 were included. Participants were categorized into four obesity phenotypes according to body mass index and metabolic status. Thyroid Feedback Quantile-based Index(TFQI), Parametric TFQI, free triiodothyronine to free thyroxine ratio(FT 3/FT 4), and sum activity of peripheral deiodinases(SPINA-GD) were calculated to evaluate thyroid hormone sensitivity. Results:Compared with metabolically healthy non-obese(MHNO) phenotype, the subjects with metabolically healthy obese(MHO) or metabolically unhealthy obese(MUO) phenotype showed higher FT 3/FT 4ratio. Metabolically unhealthy non-obese(MUNO) and MUO subjects showed lower TFQI. After adjusting for confounders, FT 3/FT 4ratio was positively associated with MHO( OR 1.18, 95% CI 1.11-1.26) and MUO phenotype( OR 1.28, 95% CI 1.19-1.39). With 1 s increase of TFQI, the OR for MUNO phenotype was 0.77(95% CI 0.64-0.94). The results of Parametric TFQI and SPINA-GD were similar to TFQI and FT 3/FT 4ratio, respectively. Conclusion:In euthyroid individuals, thyroid hormone sensitivity was positively associated with increased risk for unhealthy obesity phenotypes.

Feedback is an educational activity that occurs in a variety of settings in medical education and has been widely discussed since 2008, when Ridder et al. defined it as "Specific information about the comparison between a trainee's observed performance and a standard, given with the intent to improve the trainee's performance." (Ridder et al., 2008, p.3). Since then, discussions on effective feedback have shifted from a behaviorist, instructor-centered approach to a more multifaceted approach that focuses on relationship and the learner as recipient of feedback, or the learner's potential ability to make use of feedback (self-regulated learning, feedback literacy).
ABSTRACT
RESUMO Intervenções para a capacitação parental de famílias de crianças com deficiência auditiva, incluindo as usuárias de implante coclear, são apontadas como otimizadoras em seus resultados de desenvolvimento. Neste estudo de intervenção de caso único, temos por objetivos descrever o uso do videofeedback em ambiente remoto, bem como identificar a sua efetividade, a partir da análise da interação da mãe e criança, tanto para os comportamentos comunicativos da mãe como para os comportamentos da linguagem receptiva e expressiva da criança. Medidas pré e pós-intervenção foram realizadas, a partir da análise de vídeos de interação da mãe com a criança, por juízes cegos, bem como pela aplicação de instrumentos de avaliação da criança e da mãe. Foram realizadas 13 sessões, sendo 3 de avaliação nos momentos pré e pós-intervenção e 10 sessões de teleconsulta em que se empregou a ferramenta de videofeedback com a mãe. Os dados foram analisados de forma descritiva e inferencial, por meio do método JT, que determinou o Índice de Mudança Confiável (IMC) e a Significância Clínica. Houve mudança positiva confiável na linguagem receptiva e expressiva da criança, bem como mudança positiva confiável e mudança clínica significativa na interação da mãe com a criança após as 10 sessões de intervenção remota com videofeedback. A partir das mudanças confiáveis observadas neste estudo, apresentamos este modelo (Televideofeedback), como potencial para otimizar os recursos e esforços para o sucesso terapêutico na reabilitação auditiva infantil, o qual deve ser estudado em pesquisas com método rigoroso, para a ampla recomendação de seu uso.
ABSTRACT Interventions for parental training for families of hard of hearing children, including cochlear implant users, are identified as optimizing their developmental outcomes. In this single-case intervention study, we aim to describe the use of videofeedback in a remote environment, as well as to identify its effectiveness, based on the analysis of mother-child interaction, both for the mother's communicative behaviors and for the behaviors of the mother, receptive and expressive language of the child. Pre- and post-intervention measurements were performed, based on video analysis of the mother's interaction with the child, by blind judges, as well as through the application of assessment instruments for the child and the mother. There were 13 sessions, 3 of which were for evaluation before and after the intervention and 10 of teleconsultation sessions in which the videofeedback tool was used with the mother. Data were analyzed descriptively and inferentially, using the JT method, which determined the Reliable Change Index (BMI) and Clinical Significance. There was reliable positive change in the child's receptive and expressive language, as well as reliable positive change and clinically significant change in mother-child interaction after the 10 sessions of remote videofeedback intervention. Based on the reliable changes observed in this study, we present this model (televideofeedback) as a potential to optimize resources and efforts for therapeutic success in children's auditory rehabilitation, which should be studied in research with a rigorous method, for the broad recommendation of its use.
ABSTRACT
Resumo Introdução: A avaliação é primordial no processo de ensino-aprendizagem do médico residente. O Mini-CEX é considerado um instrumento apropriado para realizar uma avaliação formativa, permitindo um feedback educacional estruturado. Nesse contexto, os preceptores de residência precisam estar em contínuo processo de capacitação para melhor direcionar os seus residentes, e uma forma viável de capacitação é por meio do ensino a distância (EaD). Objetivo: Este estudo teve como objetivos desenvolver e validar um curso na modalidade de EaD sobre Mini-CEX para preceptores da residência em mastologia. Método: Trata-se de desenvolvimento e validação de um produto técnico-educacional no formato de curso de capacitação e na modalidade de EaD. No processo de validação de conteúdo do produto, utilizou-se a técnica de grupo de consenso. A validação semântica foi realizada através de questionário de validação aplicado aos preceptores envolvidos na residência em mastologia. Resultado: Foi elaborado e validado um curso autoinstrucional e sem mediação, com carga horária total de duas horas. O curso teve aprovação do público-alvo por apresentar um escore médio global de 98% de satisfação e um alfa de Cronbach igual a 0,8. Conclusão: O curso desenvolvido e validado sobre Mini-CEX apresenta-se como opção relevante para a formação de preceptores de residência médica em mastologia, podendo se estender para qualquer serviço de residência médica. Ressalta-se que o curso na modalidade de EaD favorece a adesão do público-alvo apresentando um formato acessível para fortalecer o conhecimento sobre o tema, além de incentivar os preceptores a utilizar a ferramenta de avaliação educacional.
Abstract Introduction: Assessment is paramount in the resident physician's teaching-learning process. The Mini-CEX is considered an appropriate instrument to carry out formative assessment, allowing structured educational feedback. In this context, residency preceptors need to undergo a continuous training process to better prepare their residents, and a viable form of training is using Distance Education (EaD). Objective: To develop and validate a Distance Education (EaD) course on Mini-CEX for residency preceptors in Mastology. Method: Development and validation of a technical-educational product, in the format of a training course and in the Distance Education modality (EaD). The consensus group technique was used in the product content validation process. Semantic validation was carried out through a validation questionnaire applied to the preceptors involved in the residency program in Mastology. Results: A self-instructional and unmediated course was designed and validated, with a total workload of 02 (two) hours. The course was approved by the target audience, as it had an overall average score of 98% satisfaction and a Cronbach's alpha equal to 0.8. Conclusions: The course developed and validated on Mini-CEX presents itself as a relevant option for the training of medical residency preceptors in Mastology and can be extended to any medical residency service. It should be noted that the Distance Education (EaD) course favors the adherence of the target audience, with an accessible format to strengthen knowledge on the subject, in addition to encouraging preceptors to also use the educational evaluation.
