Competencias digitales de docentes de Educación Física para reducir el estrés de estudiantes mediante emprendimiento en proyectos

Los emprendimientos en proyectos de la actividad física y el deporte, ante todo, han demostrado ser atractivos y curativos, por excelencia. Es muy notable esta situación en individuos que invierten gran parte de su tiempo sentados frente a un computador, como es el caso de los estudiantes en formación que desarrollan competencias digitales. En este trabajo, se consideró la necesidad de investigar la relación existente entre la labor que realizan estos estudiantes y los inconvenientes para la salud que generan las prolongadas horas que ellos invierten en su trabajo de vinculación con las competencias digitales; por lo que el objetivo consistió en determinar cuáles son las causas fundamentales que provocan el estrés en estudiantes de informática y en qué medida la actividad física que realizan les ayuda reducir estos impactos de la actividad profesional. Para lograrlo, se aplicaron métodos del nivel empírico como la observación científica, la entrevista y la encuesta. Como resultados preliminares, a partir de un prexperimento, se pudo constatar que los estudiantes percibieron un cambio satisfactorio, con niveles inferiores de estrés y mejoras de los comportamientos posturales.

Entrepreneurship in physical activity and sports projects, above all, has proven to be attractive and healing, par excellence. This situation is very notable in individuals who spend a large part of their time sitting in front of a computer, as is the case of students in training who develop digital skills. In this work, the need to investigate the relationship between the work carried out by these students and the health problems generated by the long hours they invest in their work linking with digital skills was considered; therefore, the objective was to determine what are the fundamental causes that cause stress in computer science students and to what extent the physical activity they perform helps them reduce these impacts of professional activity. To achieve this, empirical level methods such as scientific observation, interviews and surveys were applied. As preliminary results, from a pre-experiment, it was confirmed that the students perceived a satisfactory change, with lower levels of stress and improvements in postural behaviors.

O empreendedorismo em projetos de atividade física e esportivos, sobretudo, tem se mostrado atrativo e curativo, por excelência. Esta situação é muito notória nos indivíduos que passam grande parte do seu tempo sentados em frente ao computador, como é o caso dos alunos em formação que desenvolvem competências digitais. Neste trabalho foi considerada a necessidade de investigar a relação entre o trabalho realizado por esses alunos e os problemas de saúde gerados pelas longas horas que investem no seu trabalho vinculando-se às competências digitais; Portanto, objetivou-se determinar quais são as causas fundamentais que causam estresse em estudantes de informática e em que medida a atividade física que realizam os ajuda a reduzir esses impactos da atividade profissional. Para conseguir isso, foram aplicados métodos de nível empírico, como observação científica, entrevistas e pesquisas.

Comparativo da especificidade das escalas de Tinetti e SPPB na avaliação de idosos saudáveis e com disfunções neuromotoras no sul de Goiás / Comparison of the specificity of the tinetti and sppb scales in the assessment of healthy elderly people and those with neuromotor dysfunctions in southern Goiás

Introdução: o aumento da população idosa no mundo e as alterações fisiológicas decorrentes desse processo refletem a necessidade de boas ferramentas de avaliação para a identificação precoce de possíveis declínios. Objetivo: comparar os achados da avaliação pelas escalas Short Physical Performance Battery (SPPB) e Índice de Equilíbrio e Marcha de Tinetti validadas no Brasil, verificando a especificidade de cada escala na avaliação de idosos saudáveis e com disfunções neuromotoras. Métodos: 76 indivíduos, 43 saudáveis e 33 com disfunção neuromotora, de ambos os sexos, com idade mínima de 60 anos, residentes nos municípios de Caldas Novas-GO, Itumbiara-GO e Goiatuba-GO, foram avaliados em dias alternados pelas escalas SPPB e Tinetti. Resultados: os grupos apresentaram pontuações maiores nas avaliações pelo Índice Tinetti, o que sugere maior sensibilidade da SPPB na avaliação da marcha e do equilíbrio desses indivíduos. Conclusão: SPPB mostrou-se mais específica que o Índice de Tinetti, sendo capaz de detectar alterações que o Índice Tinetti não foi capaz de encontrar.

Introduction: the increase in the elderly population in the world and the physiological changes resulting from this process reflect the need for good assessment tools for the early identification of possible declines. Objective: to compare the assessment findings by the Short Physical Performance Battery (SPPB) and Tinetti's Balance and Gait Index validated in Brazil, verifying the specificity of each scale in the assessment of healthy elderly people and those with neuromotor dysfunctions. Methods: 76 individuals, 43 healthy and 33 with neuromotor dysfunction, of both sexes, aged at least 60 years, living in the cities of Caldas Novas-GO, Itumbiara-GO and Goiatuba-GO, were evaluated on alternate days by the SPPB and Tinetti scales. Results: the groups presented higher scores in the evaluations by Tinetti, which suggests greater sensitivity of the SPPB in the evaluation of gait and balance of these individuals. Conclusion: SPPB was more specific than Tinetti, being able to detect changes that the Tinetti Index was not able to find.

Effect of multi-target transcranial direct current stimulation on performance of working memory-postural control dual-task in healthy adults / 中国康复理论与实践

ObjectiveTo investigate the effect of multi-target transcranial direct current stimulation (tDCS) and single-target tDCS on the performance of working memory-postural control dual-task in healthy adults, and to compare the regulatory effect of the two stimulation protocols. MethodsFrom November, 2020 to February, 2021, 19 healthy adults in Shanghai University of Sport were recruited and randomly accepted multi-target tDCS, single-target tDCS and sham stimulation with at least one week interval between any two stimulation protocols. The target areas of multi-target tDCS included left dorsal lateral prefrontal cortex (L-DLPFC) and bilateral primary motor cortex (M1), and single-tDCS only applied to L-DLPFC. Before and after stimulation, participants completed walking and standing balance tests under single task and dual-task conditions with the second task being a N-back task. The dual-task postural control performance, dual-task cost (DTC) and working memory performance were observed before and after stimulation. ResultsSignificant differences were observed among three stimulation protocols in the changes of stride variability (F = 3.792, P = 0.029), DTC of stride variability (F = 3.412, P = 0.040) and velocity of center of pressure (Vcop) (F = 3.815, P = 0.029). The stride variability (P = 0.047) and Vcop (P = 0.015) were significantly lower and the decrease in DTC of stride variability tended to be significant (P = 0.073) following multi-target tDCS, as compared to sham stimulation. Single-target tDCS significantly decreased the changes of stride variability (P = 0.011), DTC of stride variability (P = 0.014) and Vcop (P = 0.025), as compared to sham stimulation. Compared with single target tDCS, multi-target tDCS reduced the changes of the dual-task cost of the area of center of pressure (P = 0.035). Moreover, no significant difference was observed among the three stimulation protocols in the changes of each measure in the working memory test (P > 0.05). ConclusionBoth multi-target tDCS and single-target tDCS can improve the performance of working memory-postural control dual-task in healthy adults, and compared with single-target tDCS, multi-target tDCS has some advantages in regulating postural control.

Multisensory Conflict Impairs Cortico-Muscular Network Connectivity and Postural Stability: Insights from Partial Directed Coherence Analysis / 神经科学通报·英文版

Sensory conflict impacts postural control, yet its effect on cortico-muscular interaction remains underexplored. We aimed to investigate sensory conflict's influence on the cortico-muscular network and postural stability. We used a rotating platform and virtual reality to present subjects with congruent and incongruent sensory input, recorded EEG (electroencephalogram) and EMG (electromyogram) data, and constructed a directed connectivity network. The results suggest that, compared to sensory congruence, during sensory conflict: (1) connectivity among the sensorimotor, visual, and posterior parietal cortex generally decreases, (2) cortical control over the muscles is weakened, (3) feedback from muscles to the cortex is strengthened, and (4) the range of body sway increases and its complexity decreases. These results underline the intricate effects of sensory conflict on cortico-muscular networks. During the sensory conflict, the brain adaptively decreases the integration of conflicting information. Without this integrated information, cortical control over muscles may be lessened, whereas the muscle feedback may be enhanced in compensation.

Resumo Objetivo Identificar os fatores clínico-funcionais associados ao risco de quedas, avaliado pelo Mini-BESTest, em idosos com diabetes mellitus tipo 2 (DM2). Método Trata-se de um estudo transversal. Um total de 145 idosos com idade =60 anos foram avaliados por meio das variáveis sociodemográficas (sexo, faixa etária, estado civil, nível de educação e percepção geral da saúde, audição e visão) Mini-BESTest, Mini-Mental State Examination (MMSE), Escala de Depressão Geriátrica (GDS-15) e o teste Timed Up and Go (TUG) (dupla tarefa). Foi utilizado um modelo de regressão logística múltipla. Resultados O domínio de orientação sensorial apresentou a pontuação média mais elevada, seguido pelos domínios estabilidade na marcha, ajustes posturais antecipatórios e respostas posturais. Os fatores associados ao risco de quedas em idosos foram: percepção visual ruim/muito ruim OR 3.40 (1,50-7,72); presença de doenças respiratórias OR 8.00 (1,32-48,46); sensação de tontura OR 2.53 (1,10-5,80); e tempo do teste Timed Up and Go (TUG) (dupla tarefa) igual ou superior a 13,5 segundos OR 3.31 (1,03-10,64). Conclusão Os idosos deste estudo apresentaram um equilíbrio postural comprometido, principalmente no domínio das respostas posturais. O conhecimento dos fatores associados ao risco de quedas em idosos com DM2 permite uma orientação mais eficaz na avaliação, prevenção e intervenção, visando minimizar a ocorrência de quedas e preservar ou otimizar o equilíbrio postural. Diversos fatores influenciaram esse resultado, tais como sobrepeso, baixa atividade física e nível educacional, várias comorbidades, polifarmácia, diagnóstico de DM2 por mais de dez anos, percepção negativa da saúde geral e da visão, e sintomas depressivos.

Abstract Objective Identify clinical-functional factors associated to the risk of falls, assessed by Mini-BESTest in older adults with type 2 diabetes mellitus (T2DM). Method This cross-sectional study. A total of 145 older adults aged ≥60 years were evaluated through sociodemographic variables (sex, age group, married, education level, general health status hearing and vision), Mini-BESTest, Mini-Mental State Examination (MMSE), Geriatric Depression Scale (GDS-15) and dual-task Timed Up and Go Test (TUG) Multiple logistic regression model was used. Results The sensory orientation domain presented the highest average score, followed by the gait stability, anticipatory postural adjustments and postural responses domains. Factors associated to the risk of falls in older adults are: poor/very poor visual perception OR 3.40 (1.50-7.72); have respiratory diseases OR 8.00 (1.32-48.46); feeling dizzy OR 2.53 (1.10-5.80); and TUGT (dual task) time equal to or greater than 13.5 seconds OR 3.31 (1.03-10.64). Conclusion Older adults in this study presented impaired postural balance, mainly in the postural responses domain. The knowledge of the factors associated with the risk of falls in older adults with T2DM allows for better guidance in prevention, assessment and intervention, in order to minimize the occurrence of falls and maintain or optimize postural balance. Several factors influenced this outcome, such as overweight, low physical activity and education, several comorbidities, polypharmacy, T2DM diagnosis for more than ten years, negative perception of general health and vision, and depressive symptoms.

Prevalencia de caídas y factores de riesgo intrínsecos en personas adultas mayores. Barranquilla (Atlántico), Colombia

Introducción: El riesgo de caídas es de carácter multifactorial, ya sea debido a factores extrínsecos o intrínsecos. Las caídas se consideran el principal mecanismo de lesión no intencional en los mayores. Objetivo: Determinar la prevalencia de caídas y factores de riesgo intrínsecos en personas adultas mayores de la ciudad de Barranquilla (Colombia). Materiales y métodos: Estudio descriptivo correlacional, realizado en 98 adultos mayores, tanto institucionalizados como en comunidad, residentes en Barranquilla (Atlántico), Colombia. Se aplicó una encuesta sobre factores de riesgo intrínsecos; el riesgo de caída se midió con la escala de Berg y se establecieron niveles de Vitamina D en sangre. Resultados: El promedio de edad fue de 75 años, con edades más avanzadas en población institucionalizada. La prevalencia general de caídas fue de 49 % en el último año. El 68,8 % de la población que presentó caídas fueron mujeres, con mayor proporción de caídas en los residentes en hogares geriátricos (52,1 %). Las mujeres provenientes de la comunidad se cayeron más que los hombres (91,3 %) lo cual muestra significancia estadística frente a las caídas (p = 0,002). El consumo de antihipertensivos fue el de mayor proporción (92 %), lo cual demuestra que es estadísticamente significativa para la población institucionalizada (p = 0,0224). El riesgo de caída alto y moderado fue mayor en la población institucionalizada (32 %). El 79,2 % de los individuos que presentaron caídas presentó niveles de vitamina D insuficientes. Conclusión: La población adulta mayor presenta una alta prevalencia de caídas, especialmente las mujeres y la población institucionalizada en centros geriátricos. Los hechos que presentaron significancia estadística fueron ser mujer y provenir de la comunidad, junto con el consumo de antihipertensivos en población institucionalizada.

Introduction: Fall risk can be related to multiple factors, whether they are of extrinsic or intrinsic nature. Falls are considered the main mechanism of accidental injury in the elderly. Objective: To determine the prevalence of falls and intrinsic risk factors in older adults in the city of Barranquilla (Colombia). Materials and methods: A descriptive correlation study was carried out on 98 institutionalized and community elderly adults from Barranquilla (Atlántico), Colombia. A survey on intrinsic risk factors was applied; the risk of falling was measured with the Berg scale and levels of Vitamin D in the blood were established. Results: The participant's average age was 75 years old, considering that the oldest ages were in the institutionalized population. The general prevalence of falls was 49% in the last year, 68.8% of the population that presented falls were women, and the highest proportion of falls occurred with residents of geriatric homes (52,1%). Women coming from the community fell more than men (91,3%) showing statistical significance compared to falls (p-value of 0,002). The consumption of antihypertensive drugs was the one with the highest proportion (92%), which showed statistical significance for the institutionalized population (p-value of 0,0224). The high and moderate risk of falls was higher in the institutionalized population (32%). Insufficient vitamin D levels (79,2% of those that fell) had a higher prevalence in women, without statistical significance. Conclusion: The elderly population has a high prevalence of falls, especially in women and in the population institutionalized in geriatric centers. The facts that presented statistical significance were being a woman and coming from the community, along with the consumption of antihypertensives in the institutionalized population.

Reabilitação vestibular: sua efetividade após a alta / Vestibular rehabilitation: Its effectiveness after discharge / Rehabilitación vestibular: su efectividad después del alta

ntrodução: A reabilitação vestibular é um tratamento para tontura crônica que utiliza exercícios personalizados visando restaurar o controle postural e reduzir a tontura. Pouco se discute na literatura sobre os benefícios em longo prazo desta intervenção. Objetivos: Descrever o perfil dos pacientes atendidos no Ambulatório de Reabilitação Vestibular e verificar a melhora do equilíbrio corporal após a alta fonoaudiológica. Métodos: Foram colhidas informações acerca dos dados sociodemográficos, diagnóstico, tratamento anterior e queixas existentes. As informações foram obtidas por contato telefônico e acesso aos prontuários. Os dados foram analisados estatisticamente utilizando nível de significância de 5%. Resultados: Participaram 26 indivíduos, sendo 21 (80,8%) do gênero feminino, com média de idade de 67 anos. A queixa principal foi tontura não rotatória. O resultado do teste vestibular mais comum foi hipofunção vestibular unilateral. Dentre os entrevistados, 25 (96,2%) relataram melhora dos sintomas com o tratamento, com redução da pontuação obtida no Dizziness Handicap Inventory. Sete participantes (26,9%) permaneceram assintomáticos desde o término da reabilitação. Aqueles que relataram ainda sentirem tontura, descreveram que esta possui menor intensidade que no período anterior à intervenção.Conclusão: Houve prevalência de indivíduos do gênero feminino, idosos, com ensino fundamental incompleto, sem diagnóstico otoneurológico estabelecido, com queixa de tontura não rotatória e resultado do teste vestibular de hipofunção vestibular unilateral.A reabilitação vestibular foi eficaz para redução dos sintomas apresentados. A exposição sucessiva aos exercícios após o tratamento auxilia na manutenção do equilíbrio. Contudo, a adesão à realização dos exercícios após a alta ainda é baixa. (AU)

Introduction: Vestibular rehabilitation is a treatment for chronic dizziness that uses personalized exercises aimed at restoring postural control and reducing dizziness. There is little discussion in the literature about the long-term benefits of this intervention. Objectives: To describe the profile of patients seen at the Vestibular Rehabilitation Outpatient Clinic and verify body balance improvement after speech-language-hearing therapy discharge. Methods: Sociodemographic data, diagnosis, previous treatment, and existing complaints were collected. The information was obtained via phone calls and medical records. The data were statistically analyzed using a significance level of 5%. Results: 26 individuals participated, of whom 21 (80.8%) were female, with a mean age of 67 years. The main complaint was non-rotational dizziness. The most common vestibular test result was unilateral vestibular hypofunction. Among the interviewees, 25 (96.2%) reported improved symptoms after the treatment, with reduced Dizziness Handicap Inventory scores. Seven participants (26.9%) remained asymptomatic since the end of rehabilitation. Those who still reported dizziness described it as less intense than before the intervention. Conclusion: There was a prevalence of females, older adults with incomplete middle school, no established otoneurological diagnosis, complaint of non-rotational dizziness, and vestibular test results of unilateral vestibular hypofunction. Vestibular rehabilitation effectively reduced the symptoms. Successive exposure to exercises after treatment helps maintain balance. However, adherence to exercise after discharge is still low. (AU)

Postural dysautonomia in response to head-up tilt in a military pilot aspirant: Aeromedical considerations

Intolerance to orthostasis encompasses a group of responses on assumption of upright posture. One such response is postural dysautonomia. One of the types of postural dysautonomia is postural orthostatic tachycardia syndrome, which is characterised by an increase in heart rate of more than 30 bpm without hypotension along with other features of dysautonomia on attaining an erect posture, either actively or passively. This paper brings out a case of postural dysautonomia in a pilot aspirant in response to Head-up tilt (HUT) test. A 23-year-old female military pilot aspirant reported for evaluation of Syncope and Air Sickness. She gave a history of solitary episode of loss of consciousness on ground while preparing for an early morning sortie. She was diagnosed with a case of neurocardiogenic syncope and was put back to flying training. Subsequently, after about 2 months, she developed features of air sickness while flying and also could not tolerate preliminary motion sickness desensitisation at her unit. A thorough medical evaluation failed to reveal any neurocardiological abnormality. Before commencing the air sickness desensitisation protocol at the Institute of Aerospace Medicine, she was subjected to HUT during which she developed signs and symptoms suggestive of postural dysautonomia. A test retest assessment with repeat HUT and passive standing test revealed similar responses.

Conclusão: após a reabilitação vestibular houve aumento do ganho do reflexo vestíbulo-ocular, diminuição dos impactos causados pela tontura na qualidade de vida e do sofrimento psicológico, além da melhora da função cognitiva geral e das habilidades de percepção, memória e praxia.(AU)

Introduction: Studies have reported improved cognitive skills after vestibular rehabilitation (VR). However, they used cognitive screening tests or other ones that assess specific cognitive skills, not assessing cognition in detail. Objective: To assess cognitive skills, depressive symptoms, functioning, and sociodemographic aspects in older adults with vestibular dysfunction before and after vestibular rehabilitation. Method: Longitudinal, analytical, quasi-experimental study. The sample had 11 older adults aged 60 to 89 years, of both sexes, all of them with vestibular dysfunction verified with VEMP and/or vHIT examination. Participants were submitted to cognitive, functioning, and depressive symptoms assessment before and after eight weekly VR sessions. Results: MMSE was associated with educational attainment and DHI; the Pfeffer questionnaire was correlated with DHI; GDS-15 was correlated with VAS and BBS. After VR, there were improvements in gain in the right anterior semicircular canal, VAS, DHI and its physical, functional, and emotional subscales, GDS-15, and Neupsilin total score and its perception, memory, and praxis subscales. Conclusion: After VR, the vestibulo-ocular reflex gain increased, the impacts of dizziness on the quality of life and the psychological suffering decreased, and the overall cognitive function and perception, memory, and praxis skills improved.

Measurement properties of the Brazilian Portuguese version of the Lower-Extremity Motor Activity Log for chronic hemiparetic poststroke patients / Propriedades de medida da versão brasileira da Lower-Extremity Motor Activity Log para pacientes hemiparéticos crônicos pós-AVC

Abstract Background Stroke is among the three leading causes of disability around the world, and it results in immediate difficulty in mobility and gait. There is a lack of instruments to evaluate what daily life is like for these individuals using their lower limbs in real-life environments (outside of the clinical environment). Objective To perform the translation and cultural adaptation to Brazilian Portuguese of the Lower-Extremity Motor Activity Log (LE-MAL) and test its measurement properties in chronic poststroke individuals. Methods The LE-MAL was translated into Brazilian Portuguese and adapted to the Brazilian culture. The comprehension and relevance of the final version were analyzed by a committee of specialists. The reliability, validity, and responsiveness of the LE-MAL/Brazil to detect changes after lower extremity constraint-induced movement therapy (LE-CIMT) and an intensive conventional therapy were tested. Results The LE-MAL/Brazil showed excellent inter- and intrarater reliability, with an intraclass correlation coefficient and Cronbach alpha > 0.70, as well as standard error of measurement and smallest detectable change < 10% of the total instrument score when applied by the same evaluators. Conclusion The responsiveness of the LE-MAL/Brazil to detect changes showed better results after LE-CIMT than after the intensive conventional therapy, with most of the correlations > 0.50.

Todas responderam ao questionário Victorian Institute of Sports Assessment for Gluteal Tendinopathy (VISA-G) para análise da capacidade física relacionada a dor lateral do quadril, e foram submetidas à avaliação do controle postural na plataforma de força, em apoio unipodal estático e dinâmico (mini agachamentos). Os dados foram comparados e correlacionados, com significância estatística estabelecida 5%. Resultados: As participantes do GD apresentaram alto índice de dor (7), por 10 meses e baixa capacidade funcional (54,44 pontos no VISA-G). Na análise do controle postural estático, GD mostrou piores resultados para a área de oscilação do COP (p= 0,04) e maior amplitude de oscilação médio-lateral (p= 0,03). Na avaliação dinâmica, os resultados da amplitude médio-lateral (p= 0,02) e velocidade antero posterior (p= 0,04) foram maiores no GD, mas o COP foi pior no GC (p= 0,01). Conclusão: Mulheres com SDGT tem baixa capacidade funcional e pior controle postural estático e dinâmico. Estas variáveis devem ser avaliadas para estabelecer novas estratégias de prevenção e reabilitação em mulheres com SDGT

Objective: To establish physical capacity and changes in postural control (PCO) during static and dynamic single-legged support in women with Greater Trochanter Pain Syndrome (GTPS). Methods: A total of 36 sedentary women over 45 years of age were evaluated. Of these, 18 had a diagnosis of GTPS (Pain Group - DG), and 18 had no pain complaints (Control Group - CG). All participants answered the Victorian Institute of Sports Assessment for Gluteal Tendinopathy (VISA-G) questionnaire to analyze their physical capacity regarding lateral hip pain. Therefore, were submitted to the evaluation of postural control on the force platform in static and dynamic single-legged support (mini squats). The data were compared and correlated, with statistical significance established at 5%. Results: The participants in the DG presented a high pain index (7) for 10 months and low functional capacity (54.44 points in the VISA-G). In the analysis of static postural control, DG showed worse results for the Center of Pressure (COP) oscillation area (p= 0.04) and greater amplitude of mediolateral oscillation (p= 0.03). In the dynamic evaluation, the results of the mediolateral amplitude (p= 0.02) and anteroposterior velocity (p= 0.04) were higher in the DG, but the COP was worse in the CG (p= 0.01). Conclusion: Women with GTPS have lower functional capacity and worse static and dynamic postural control. These variables should be evaluated to establish new prevention and rehabilitation strategies for women with GTPS

Oscilações no equilíbrio estático relacionadas a diabetes mellitus tipo 2 ­ uma revisão sistemática / Oscillations in static balance related to type 2 diabetes mellitus ­ a systematic review

INTRODUÇÃO: A diabetes mellitus tipo 2 (DM2) é uma doença crônica sistêmica ligada às mudanças no estilo de vida, fatores genéticos e ambientais, ocasionando complicações como a neuropatia diabética periférica (NDP). Além disso, pessoas com DM2 apresentam um retardo na condução nervosa das vias motoras e sensoriais, podendo levar a alterações no equilíbrio. OBJETIVO: Descrever as alterações de equilíbrio estático em pacientes com DM2. MATERIAIS E MÉTODOS: A revisão sistemática iniciou em outubro de 2021 ocorrendo a última busca em março de 2023, os artigos foram selecionados por dois autores de forma independente nas bases de dados Pubmed, Scopus e Web of Science. Seguindo o protocolo registrado no PROSPERO e descrito com base nas recomendações do PRISMA, foram selecionados estudos observacionais sem restrição a ano de publicação e idioma, envolvendo equilíbrio de DM em qualquer idade. RESULTADOS: Foram eleitos 20 artigos com indivíduos DM e NPD em um total de 1564 voluntários, demonstrando: DM causa mudança na velocidade e deslocamento do COP alterando o equilíbrio estático, a presença da NPD piora a estabilidade corporal devido as alterações sensitivo motoras. CONCLUSÃO: Indivíduos com DM e NPD demonstram alterações na estabilidade postural como velocidade e deslocamento do centro de pressão (COP) para as direções AP e ML, com ou sem informação visual e na presença da NPD.

INTRODUCTION: Type 2 diabetes mellitus (DM2) is a chronic systemic disease linked to changes in lifestyle, genetic and environmental factors, causing complications such as peripheral diabetic neuropathy (PDN). In addition, people with DM2 have a delay in nerve conduction in motor and sensory pathways, which can lead to changes in balance. OBJECTIVE: To describe static balance changes in patients with DM2. MATERIALS AND METHODS: The systematic review started in October 2021 with the last search occurring in March 2023, the articles were selected by two authors independently from the Pubmed, Scopus and Web of Science databases. Following the protocol registered in PROSPERO and described based on the PRISMA recommendations, observational studies were selected without restriction on year of publication and language, involving DM balance at any age. RESULTS: 20 articles were chosen with DM and NPD individuals in a total of 1564 volunteers, demonstrating that DM causes changes in the speed and displacement of the COP, altering the static balance and the presence of NPD worsens body stability due to sensory-motor changes. CONCLUSION: Individuals with DM and NPD demonstrate changes in postural stability such as velocity and displacement of the center of pressure (COP) for the AP and ML directions, with or without visual information and in the presence of DPN.

Effect of therapeutic postural placement on postural control and balance in stroke patients with hemiplegia / 中国康复理论与实践

ObjectiveTo explore the effect of therapeutic postural placement on postural control and balance in stroke patients with hemiplegia. MethodsFrom January, 2020 to June, 2022, 60 stroke patients in Cangzhou Hospital of Integrated TCM-WM•Hebei were randomly divided into control group (n = 30) and observation group (n = 30). Both groups accepted routine rehabilitation, while the observation group accepted therapeutic postural placement based on the concept of Bobath additionally. Fugl-Meyer Assessment-Lower Extremity (FMA-LE), Berg Balance Scale (BBS), Postural Assessment Scale for Stroke Patient (PASS) and Pro-kin balance instrument were used to evaluate the postural control and balance function before and four weeks after treatment, while the area of ellipse and length of motion with eyes open and closed were recorded, respectively. ResultsAfter treatment, the scores of FMA-LE, PASS and BBS significantly increased (|t| > 3.856, P < 0.001), and the area of ellipse and length of motion with eyes open and closed decreased in both groups (|t| > 4.083, P < 0.001); all the indexes were better in the observation group than in the control group (|t| > 2.261, P < 0.05). ConclusionThe therapeutic postural placement could effectively improve the postural control ability and balance function in stroke patients.

Assessment of Rare Case on Patient with Filariasis-Associated Bilateral Pleural Effusion

@#Bilateral pleural effusion is fluid accumulation in both lungs of pleural spaces. The clinical manifestations of bilateral pleural effusion (chylothorax) caused by filariasis are so rare that they are often challenging to diagnose. This case study described a 21-year-old woman, domiciled in Sumatra, with complaints of shortness of breath and swollen legs. Radiological examination results found bilateral pleural effusion. Initially, it was suspected that the effusion was caused by tuberculosis, Systemic Lupus Erythematosus (SLE), and malignancy; however, treatments for these did not improve the patient’s condition. A Water Seal Drainage (WSD) was inserted and a chylous or chylothorax pleural effusion was obtained, and microfilaria was founded in the nocturnal blood examinations. Oxygen and nursing interventions were administered using lung expansion and postural drainage techniques, supported by education on effective coughing and deep breathing, along with the fulfillment of nutritional needs and dietary adjustments

Evaluation method of dynamic postural stability for functional ankle instability based on acceleration signals / 中国康复理论与实践

ObjectiveTo compare the retest reliability and discriminant validity of dynamic postural stability indices for functional ankle instability (FAI) obtained by different algorithms based on acceleration signals at different positions of human body. MethodsFrom April to June, 2021, 21 subjects with unilateral FAI and 21 subjects with normal ankle were recruited. Three inertial sensors were attached to the waist points, knee and ankle positions. The ground reaction force (GRF) and kinematics data of the subjects in multi-direction single leg landing test were collected synchronously by 3D force plate and inertial sensors. The unbounded third order polynomial (UTOP) fitting method was used to calculate the stability time, and the root mean square was used to caculate the stability index. ResultsMost of the indicators calculated based on acceleration signal correlated with that based on GRF with low coefficient (|r| = 0.116 to 0.368, P < 0.05). The stability time and stability index based on the acceleration signals of different positions of human body showed low to high retest reliability (CMC 0.30 to 0.91). For the females, among the stability time based on acceleration signal, eleven indexes achieved average to very high discriminant validity (AUC = 0.702 to 0.942, P < 0.05); eight of the stability indexes reached general level of discriminant validity (AUC = 0.717 to 0.782, P < 0.05). No algorithms achieved good discriminant effect in male subjects. ConclusionBased on the acceleration signal of waist point in single-leg landing stability test, the stability time calculated by UTOP algorithm can evaluate the dynamic postural stability of female FAI patients with high discriminant validity and medium to high retest reliability.

The effects of dynamic instability training on the postural control, balance and walking of stroke survivors / 中华物理医学与康复杂志

Objective:To observe any effect of dynamic motor instability training on the balance and postural control of stroke survivors.Methods:Forty stroke survivors with poor balance were randomly divided into a control group and an observation group, each of 20. In addition to routine rehabilitation, the observation group was given 20 minutes of dynamic motor instability training, 5 days a week for 8 weeks, while the control group underwent routine rehabilitation for the same length of time. Before and after the intervention, surface electromyogram of the rectus femoris, biceps femoris, and erector spinae were recorded during perturbation. Activation time and the intensity of the anticipatory and complementary postural adjustments (APAs and CPAs) were also observed. Balance and lower limb motor functioning were assessed using the Berg balance scale (BBS), the Fugl-Meyer lower extremity assessment (FMA-LE), and GaitWatch analysis.Results:After the treatment the average activation time of the rectus femoris, biceps femoris in the affected side and those of the biceps femoris [(-84.31±5.74)s] and erector spinae in the intact side in APAs were all significantly shorter in the observation group than in the control group, while the average activation intensity of the rectus femoris and erector spinae was significantly greater. There was no significant difference in the activation intensity of each muscle group in CPAs after the treatment. After the intervention the average BBS score, FMA-LE score, stride length and walking speed of the observation group all were significantly better than the control group′s averages.Conclusions:Supplementing traditional rehabilitation training with dynamic motor instability training can further improve the posture control of stroke survivors and promote recovery of their balance and walking ability.

The effects of activating the reticulospinal tract on anticipatory postural adjustments in fine motor movements of the upper extremities / 中华物理医学与康复杂志

Objective:To observe any dependence of anticipatory postural adjustment (APA) on the difficulty of fine upper limb tasks and to document any effect of reticulospinal tract (RST) facilitation on APAs during such tasks.Methods:The study′s bivariate mixed design involved 4 different tasks and 3 different priming states. Thirteen healthy, male, right-handed subjects were recruited. They were asked to complete the 4 tasks of reaching, grasping a cup, pinching a card using the thumb or using the little finger, respectively for 10 times 1 in response to two different starting cues delivered through an earphone. Half of the trials with each task were initiated with 114dB white noise to startle and activate the reticulospinal tract (RST), while the others were activated with 80dB beeps as a control. Electromyographic signals were recorded from the bilateral sternocleidomastoid (SCM), lower trapezius (LT), latissimus dorsi (LD), lumbar erector spinae and right anterior deltoid muscles and also from the right flexor and extensor carpi radialis muscles (ECR/FCR). In the subsequent processing the electromyographic time domain and frequency domain indicators were converted into a pre-motor reaction time, a time to muscle peak contraction, an activation latency, and APA or compensatory postural adjustment (CPA) amplitude of the tested muscles. These were compared among the different tasks and stimuli. In addition, the 114dB test tasks were classified as two different priming status as SCM + and SCM - according to whether the sternocleidomastoid muscle (SCM) was activated in advance. Results:After RST activation the pre-motor reaction time and the time to peak contraction of all of the muscles were significantly shortened in all of the tasks. The deltoid muscle reaction times in the SCM + , SCM - and control states were (106.89±43.78)ms, (136.78±48.74)ms and (168.60±73.17)ms, respectively, and those differences are significant. The APA amplitudes of the contralateral LT and ipsilateral LD were significantly greater than normal, but the timing of muscle activation onset and the APA/CPA amplitudes of the ECR/FCR were not affected. The latency in the anticipatory muscle activation of the ECR in the little finger grip task was significantly shorter than that in reaching. Conclusions:The extensor carpi radialis show task-specific early activation in fine tasks of the upper limbs with different difficulties. RST activation can lead to early starting of expected actions, accelerate muscle contraction and increase APA amplitude of some trunk muscles, but it has no significant effect on APA/CPA amplitudes in the forearm muscles.

Individual factors associated with postural adjustment during adaptive equilibrium / 中国康复理论与实践

ObjectiveTo investigate the individual factors of postural adjustment reaction time and movement time during adaptive equilibrium. MethodsFrom March to December, 2021, 126 healthy adults aged 18 to 80 years were recruited at the First Medical Center of the General Hospital of the Chinese PLA. The DE-A somatosensory balance detection system was used to detect their postural adjustment reaction time (RT) and movement time (MT) as the platform tilting in multiple directions during standing (static) or walking (dynamic). The ages, genders, body mass index (BMI) and physical activity level of them were investigated. ResultsThe age was the only factor independently associated with dynamic RT and MT in all the directions (β > 0.632, P < 0.05). For static MT, as the platform tilting forward, physical activity level (β = -0.143, P < 0.05), BMI (β = 0.154, P < 0.05) and age (β = 0.663, P < 0.05) were the independently associated factors; as the platform tilting leftward, gender (β = -0.173, P < 0.05) and age (β = 0.647, P < 0.05) were the independently associated factors; and age was the only independently associated factor for other directions (β > 0.571, P < 0.05). For the static RT, age was the only independently associated factor for all the directions (β > 0.615, P < 0.05). ConclusionAge is the most important independently factor related to postural adjustment during adaptive equilibrium, and aging may delay the postural adjustment after instability.
