Comparação da resposta hemodinâmica entre terapia convencional e realidade virtual em pacientes com insuficiência cardíaca internados na unidade de emergência / Comparación de la respuesta hemodinámica entre la terapia convencional y la realidad virtual en pacientes con insuficiencia cardiaca ingresados en urgencias / Comparison of hemodynamic responses between conventional and virtual reality therapies in patients with heart failure admitted to an emergency room

RESUMO O objetivo deste estudo foi avaliar e comparar a resposta aguda de parâmetros hemodinâmicos de acordo com o uso de realidade virtual (RV) semi-imersiva e terapia convencional (TC) em indivíduos internados no serviço hospitalar de emergência por insuficiência cardíaca (IC). Trata-se de estudo de viabilidade com 11 indivíduos submetidos a sessões de terapia com e sem o uso da RV. Na TC, os participantes realizaram alongamentos, exercícios ativos ou ativo-assistidos e inspiração fracionada. Já na terapia com realidade virtual (TRV) utilizou-se os óculos VR box - virtual reality glasses aplicando VR relax associado à TC. Os parâmetros hemodinâmicos avaliados foram: frequência cardíaca, pressão arterial sistólica e diastólica e saturação de oxigênio. Para análise, foram utilizados os testes t de Student e de Mann-Whitney (p<0,05). Ao avaliar os parâmetros hemodinâmicos basal e final em ambos os grupos, não foi verificada diferença significativa entre os momentos (p>0,05). Com relação à comparação das variações absolutas entre a TC e a TRV, não foi observada diferença significativa entre as respostas hemodinâmicas (p>0,05). Os resultados demonstraram que a implementação da TRV e da TC promoveram alterações fisiológicas nas respostas dos parâmetros hemodinâmicos em indivíduos com IC hospitalizados em uma unidade de emergência, não havendo diferenças significativas entre as duas intervenções. O estudo sugere que a RV é um método hemodinamicamente seguro para aplicação em unidade de emergência.

ABSTRACT This study aimed to evaluate and to compare the acute response, due to semi-immersive virtual reality (VR) and conventional therapies (CT), of hemodynamic parameters in hospitalized individuals admitted to an emergency unity for heart failure (HF). This is a viability study with 11 individuals subjected to sessions with and without VR. At CT, stretching, active or active-assisted exercises, and fractional inspiration were performed. In VR therapy (VRT), VR box glasses were used to promote VR relaxation associated with CT. The hemodynamic parameters evaluated were heart rate, systolic and diastolic blood pressure, oxygen saturation, and double product. To analyze them, Student's t- and Mann Whitney tests were used (p<0.05). Comparing baseline and final evaluations showed no significant differences in the hemodynamic parameters of both groups (p>0.05). Comparing absolute variations between CT and VRT also produced no significant differences between hemodynamic responses (p>0.05). Results showed that administering VRT and CT promoted physiological changes in the responses of hemodynamic parameters in individuals with HF hospitalized in an emergency unit without significant differences between the two interventions. This study suggests that VRT is a hemodynamically safe method for treating patients in emergency units.

Dance therapy as an alternative for cardiac rehabilitation in women population: autonomic and hemodynamic acute responses - a crossover clinical trial protocol

Abstract Aim: The objective of this study is to 1. Investigate in women with cardiac risk factors the acute responses of cardiac autonomic modulation and hemodynamic parameters during and after a dance-based cardiac rehabilitation session and II. Compare these responses with a conventional exercise-based cardiac rehabilitation session. Methods: This will be a crossover-clinical trial that will enroll women with at least one cardiac risk factor. The interventions consist of one dance-based (DB) and one traditional exercise-based (EB) session of cardiac rehabilitation, both composed of initial rest, warm-up, moderate-intensity physical exercise, fast recovery evaluation in orthostatic position, and slow recovery evaluation. The main outcomes are 1. Autonomic modulation, evaluated through heart rate variability linear and non-linear methods, and II. Hemodynamic parameters (heart rate, blood pressure, peripheral oxygen saturation, and respiratory rate). All measures will be evaluated in specific moments during the initial rest, physical exercise, and recovery. Conclusion: The results will allow the safe inclusion of dance-based sessions in cardiac rehabilitation programs opening an important field of research to investigate the long-term effects on physical fitness and cardiac risk factors, as well as adherence and motivation to attend cardiac rehabilitation in the women population.

Short-Term Effects of a Resistance Training Program Using Elastic Tubing in Patients with Heart Disease

Abstract Background Resistance training is effective in cardiac rehabilitation; however, it is conventionally performed using free weights or machines, which can pose logistic challenges to patients with restricted mobility. For its ease of access and cost-effectiveness, elastic tubing is a particularly appealing alternative, but it remains underutilized for this purpose. Objective To evaluate muscle strength, functional capacity, aerobic capacity, and quality of life in patients with heart disease in phase II of cardiovascular rehabilitation after a resistance training intervention based solely on elastic tubing. Methods Thirteen patients with heart disease (age 63.33±10.80 years) trained with elastic tubing twice weekly for 6 weeks, with progressive load increase every 15 days. The following muscle groups were evaluated and trained: shoulder abductors and flexors, elbow flexors, and knee flexors and extensors. Muscle strength was evaluated using a dynamometer; functional capacity, with a 6-minute walk test and cardiopulmonary exercise test; and quality of life, using the SF-36 questionnaire. Data normality was assessed using the Shapiro-Wilk test. The paired Student's t-test was used for comparisons before and after training, at a significance level of <5%. Results There were significant differences in muscle strength (except for elbow flexion) and functional capacity (485.5 ± 123.3 vs 578.7 ± 110.5; p=0.0399) after the intervention. No statistical differences were found in cardiorespiratory fitness or quality of life. Conclusions Short-term resistance training with elastic tubing improved peripheral muscle strength and functional capacity in patients with heart disease, and should be encouraged for this population.

Effects of conventional and virtual reality cardiovascular rehabilitation in body composition and functional capacity of patients with heart diseases: randomized clinical trial / Efeitos da reabilitação cardiovascular convencional e da realidade virtual na composição corporal e na capacidade funcional de pacientes cardiopatas: triagem clínica randomizada

Background: Virtual reality is an alternative therapeutic resource to be inserted into cardiovascular rehabilitation, stimulating the practice of physical activity through man-machine interaction. Objective: To compare the effects of conventional and virtual reality cardiac rehabilitation on body composition and functional capacity in patients with heart disease. Methods: Randomized clinical trial with 27 cardiac patients divided into conventional rehabilitation group (CRG) and virtual reality rehabilitation group (VRG). They underwent a rehabilitation program with 60-minute training sessions twice a week for eight weeks. The VRG training consisted of exercises from the Xbox 360® with Kinect™, using YourShape™ and Dance Central 3™ games. The CRG used conventional treadmills for aerobic exercise and free weights for resistance exercise. Bioimpedance and 6-minute walk test (6MWT) were evaluated at baseline and after training. For main outcome analysis, Student t and Mann Whitney tests were used with a 5% significance level. Results: The VRG showed a significant increase in body fat percentage and fat weight when compared to the CRG, and a smaller amount of total water. There was a significant improvement in functional capacity evidenced by the increase in the distance covered in the 6MWT (54.00 m and 32.25 m in the CRG and VRG, respectively), but the gains did not differ between the groups. Conclusion: The two rehabilitation modalities had no effect on the body composition of the groups. In addition, the improvement in functional capacity was similar in both groups

Perfil do desenvolvimento motor em escolares com excesso de peso / Profile of the motor development in children with overweight

INTRODUÇÃO: Diferenças relacionadas ao peso e às habilidades motoras em crianças em idade escolar ainda apresentam controvérsias. OBJETIVO: Analisar a relação entre desenvolvimento motor e nível de atividade física com o índice de massa corporal (IMC) de escolares com excesso de peso. MÉTODOS: Foram avaliados 85 escolares de ambos os sexos, de 6 a 10 anos, de Presidente Prudente, São Paulo, Brasil. Os instrumentos utilizados foram a classificação do IMC/idade, a Escala de Desenvolvimento Motor e o Questionário do Nível de Atividade Física Modificado e Adaptado. A amostra foi dividida em dois grupos: grupo com excesso de peso (GEP), com 50 escolares com diagnóstico nutricional de sobrepeso e obesidade; e grupo com normopeso (GNP), com 35 escolares eutróficos. Para análise dos dados obtidos foram utilizados: Shapiro Wilk (normalidade), teste t de Student não pareado ou Mann Whitney (amostras independentes), teste de Spearman (correlação) e teste do χ2 (proporção), com nível de significância p<0,05. RESULTADOS: O GEP apresentou resultados inferiores significantes no desenvolvimento motor geral (91,32±10,68 versus 97,14±9,06; p=0,010), nas áreas de motricidade fina ­ QM1 (93,21±21,59 versus 103,1±13,12; p=0,0138) e motricidade global ­ QM2 (90,31±23,54 versus 112,6±16,07; p<0,0001). Observou-se correlação positiva significativa entre o nível de atividade física e o desenvolvimento motor no GEP, nas áreas de equilíbrio ­ QM3 (0,35080; p=0,0125) e organização espacial ­ QM5 (0,41820; p=0,0025). CONCLUSÃO: O GEP, quando comparado com o GNP, demonstrou resultados inferiores no quociente motor geral (QMG), QM1 e QM2.

INTRODUCTION: In school-age children, differences in weight and motor skills are still controversial. OBJECTIVE: To analyze the relation between motor development, level of physical activity, and body mass index (BMI) in children with overweight. METHODS: 85 students of both genders, aged 6 to 10 years, living in Presidente Prudente, São Paulo, Brazil, were evaluated. The instruments used were: the classification of BMI/age, the Motor Development Scale and the Modified and Adapted Questionnaire of Level of Physical Activity. The sample was divided into two groups: the overweight group (OWG) was composed of 50 students with nutritional diagnosis of overweight and obesity; the normal weight group (NWG) was composed of 35 eutrophic students. The following tests were used for statistical analysis: Shapiro Wilk (data normality), Student's t test or Mann-Whitney (independent samples), Spearman's test (correlation) and χ2 test (proportion), with significance level set at p<0.05. RESULTS: The OWG had significantly lower results for general motor development (91.32±10.68 versus 97.14±9.06; p=0.010), fine motricity (93.21±21.59 versus 103.1±13.12; p=0.0138) and gross motricity (90.31±23.54 versus 112.6±16.07; p=0.0001). A significant positive correlation was found between level of physical activity and motor development in OWG subjects in the domains balance (0.35080; p=0.0125) and spatial organization (0.41820; p=0.0025). CONCLUSION: When OWG is compared to NWG, results are inferior for general motricity, fine motricity, and gross motricity.
