RESUMEN

Objective: This systematic review and meta-analysis updated the effects of photobiomodulation therapy (PBMT) on pain, the Foot Function Index (FFI), and the effects on fascial thickness in adults with acute or chronic plantar fasciitis (PF). Methods: A systematic literature search was conducted in the PubMed (Public/Publisher MEDLINE), EMBASE (Excerpta Medica Database), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. Two researchers independently screened titles and abstracts of the retrieved studies for eligibility. A random-effects model was used for this meta-analysis. Subgroup meta-analyses were conducted to evaluate the influence of PBMT in pain and foot function under investigation and the study design on the overall weighted mean effect size. Results: From a total of 3865 studies, 7 randomized controlled trials were selected after final review and 4 were selected for meta-analysis. There was a significant difference between PBMT and control for Visual Analog Scale (Chi2 = 29.30; p < 0.00001) with an I2 value of 90% in favor of PBMT versus the control. The overall effect of PBMT was statistically significant (p < 0.02) with PBMT favoring for thickness of the plantar fascia reduction. FFI between PBMT and control group [Chi2 -83.46, df = 1 (p < 0.00001)]; I2 = 99% in favor of the PBMT. Conclusions: This meta-analysis presents evidence that PBMT is an effective treatment modality to reduce pain and improvement of foot function in patients with chronic PF, however, a broad discrepancy was found in the PBMT dosimetry. The ideal treatment parameters for PF need to be elucidated.

RESUMEN

RESUMO A frequência cardíaca sofre variações durante o ciclo respiratório, fenômeno conhecido como arritmia sinusal respiratória. A manobra para acentuação da arritmia sinusal respiratória (M-ASR) consiste em manter ventilação educada com uma frequência respiratória de seis ciclos por minuto com relação tempo inspiração/expiração (TI:TE) de 1:1. Este estudo tem como objetivo avaliar o comportamento do volume minuto, da fração expirada de CO2 (FeCO2 infere sobre PaCO2) e do controle autonômico da frequência cardíaca durante a M-ASR com duração maior do que 90s. Foram avaliados 16 homens jovens saudáveis (de 18 a 25 anos). Todos foram orientados a realizar inspirações e expirações lentas com duração de 10 segundos por ciclo, TI:TE de 1:1 e consequente frequência respiratória de seis incursões por minuto, durante quatro minutos. Durante a avaliação foi coletada a frequência cardíaca (FC) batimento a batimento por meio de um cardiofrequencímetro, o volume minuto (VM) e a FeCO2 através de um ergoespirômetro. Para análise estatística empregou-se ANOVA one-way (com post-hoc de Tukey) ou teste de Kruskal-Wallis (com post-hoc de Dunn) quando conveniente (p<0,05). Durante a M-ASR, a FeCO2, o VM e os índices do domínio do tempo da variabilidade da frequência cardíaca (VFC) não sofreram alterações significativas ao longo do tempo. A realização da M-ASR em jovens saudáveis, por mais de 90 segundos, pode ser executada com segurança, sem o risco de hipocapnia e sem a interferência das alterações de FeCO2 nos índices do domínio do tempo da análise de VFC da M-ASR.


RESUMEN La frecuencia cardíaca sufre oscilaciones durante el ciclo respiratorio, fenómeno conocido como arritmia sinusal respiratoria. La maniobra para acentuación de la arritmia sinusal respiratoria (M-ASR) consiste en mantener ventilación educada con frecuencia respiratoria de seis ciclos por minuto con relación al tiempo inspiración/espiración (TI:TE) de 1:1. En este estudio se propone a evaluar la conducta del volumen minuto, de la fracción espirada de CO2 (FeCO2 infiere sobre el PaCO2) y el control autonómico de la frecuencia cardíaca durante la M-ASR con duración mayor de 90s. Se evaluaron 16 varones jóvenes sanos (de 18 a 25 años de edad). Se les orientaron para que realizasen inspiraciones y espiraciones pausadas de 10 segundos de duración por ciclo, TI:TE de 1:1, y consecuente frecuencia respiratoria de seis incursiones por minuto, durante cuatro minutos. Durante la evaluación se recolectaron la frecuencia cardíaca (FC), latido a latido a través de un monitor de frecuencia cardíaca, el volumen minuto (VM) y la FeCO2 mediante un ergoespirómetro. Para el análisis estadístico se empleó ANOVA one-way (con post-hoc de Tukey) o test de Kruskal-Wallis (con post-hoc de Dunn) cuando necesario (p<0,05). Durante la M-ASR, la FeCO2, el VM y los índices del dominio del tiempo para la variabilidad de la frecuencia cardíaca (VFC) no presentaron alteraciones significativas al largo del tiempo. Puede ejecutarse con seguridad la realización de la M-ASR en jóvenes sanos por más de 90 segundos, sin riesgo de hipocapnia y sin interferencia de las alteraciones de la FeCO2 en los índices del dominio del tiempo para analizar la VFC de la M-ASR.


ABSTRACT Heart rate (HR) fluctuate during the respiratory cycle. This phenomenon is known as respiratory sinus arrhythmia. The deep breathing test is to keep a paced breathing in six breathing per minute and I:E relationship 1:1. The purpose of this study is to access minute volume, expired fraction of carbon dioxide (EFCO2) and autonomic control of heart rate during deep breathing test longer than 90 seconds. Sixteen young healthy male (18 - 25 years old) were assessed. The subjects were instructed to perform inspirations and expirations with duration of 10 seconds per cycle, I:E = 1:1, and consequently respiratory rate of 6 cycles per minute, for about four minutes with one minute after and before, totaling six minutes. HR was recorded beat-to-beat using a cardio frequencimeter; MV and EFCO2 was measured and recorded using a mobile ergoespirometer. To analyse statistics differences, ANOVA one way (Tuckey post-hoc) and Kruskall Wallis (Dunn post-hoc) were used (p<0.05). When deep breathing test in course, EFCO2, MV and time domain heart rate variability shows no statistics difference over time. To perform deep breathing test in young healthy male, longer than 90 seconds, can be safety, without risks of hypocapnia and no interference from EFCO2 changes in time domain heart rate variability analysis of M-RSA.

RESUMEN

BACKGROUND: The adequate control of asthma includes the absence of nocturnal symptoms, minimal use of medication, normal or nearly normal lung function and no limitations to physical activity. The choice of a more sedentary lifestyle can lead to physical de-conditioning, thereby aggravating asthma symptoms and increasing the risk of obesity. METHODS: This study aimed at performing a battery of function-related assessments in patients with asthma and comparing them to a healthy control group. A prospective, transversal and case-control study was designed. It was set up at Santa Casa de Misericórdia Hospital -Sao Paulo and Nove de Julho University on a population of outpatients. Subjects of the study were patients affected by moderate to severe asthma. A case-control study was carried out involving 20 patients with moderate to severe asthma and 15 healthy individuals (control group). All participants underwent body composition analysis (BMI and BIA) and a controlled walk test (Shuttle test), resistance muscle test (1RM) and answered a physical activity questionnaire (IPAQ). The group with asthma also answered a questionnaire addressing the clinical control of the illness (ACQ). RESULTS: In comparison to the control group (unpaired Student's t-test), the patients with asthma had a significantly higher BMI (31.09 ± 5.98 vs. 26.68 ± 7.56 kg/m(2)) and percentage of body fat (38.40 ± 6.75 vs. 33.28 ± 8.23%) as well as significantly lower values regarding distance traveled on the walk test (369 ± 110 vs. 494 ± 85 meters) and metabolic equivalents (3.74 ± 0.87 vs. 4.72 ± 0.60). A strong correlation was found between the distance completed and peripheral muscle strength (r: 0.57, p < 0.05) and METs (Metabolic equivalents - minutes/week) and peripheral muscle strength of 1RM (r: 0.61, p = 0.009). CONCLUSIONS: The individuals with asthma had lower functional capacity and levels of physical activity as well as a higher percentage of body fat compared to healthy individuals. This suggests that such patients have a reduced physical performance stemming from a sedentary lifestyle. Despite the existence of few studies reporting moderate to severe asthmatic patients and functional capacity assessment, it is clear that the assessment presented in the current study is a valid and accessible tool in clinical practice.

RESUMEN

Congenital heart defects affect the efficiency and functionality of the heart, and autonomic control of heart rate and of circulation can display a pathologic behavior in order to compensate for the hemodynamic alterations due to disease. While previous works have investigated heart rate variability (HRV) in specific pathologies, e.g. tetralogy of Fallot, the goal of this study was to assess HRV in children with a congenital heart malformation taking into account the effects of cyanotic and acyanotic defects, and comparing pathologic children with age matched controls. HRV, approximate entropy (ApEn) and sample entropy (SampEn) were calculated to discuss the dynamics and complexity of heart rhythms, and to evaluate the potential impairment of control mechanisms. Analyses showed that low frequency (LF) power and total power of HRV were significantly higher in children with a condition than in healthy controls, independently of cyanosis. Non linear indices were also significantly higher in pathologic subjects. Significant differences in LF, total power, ApEn and SampEn were found among cyanotic, acyanotic and healthy children. These results suggested that children with a congenital heart condition display more complex HRV and sympathetic overactivity, which may be aimed at compensating for hemodynamic alterations. Further studies should investigate whether corrective surgery and rehabilitation can improve HRV and restore its physiological features.

RESUMEN

Objetivo: Comparar o comportamento do consumo de oxigênio (VO2), ventilação pulmonar (VE) e da saturação periférica de oxigênio (SpO2) durante o Teste do degrau (TD6) e Teste de caminhada de seis minutos (TC6), em indivíduos saudáveis e com doença pulmonar obstrutiva crônica (DPOC), além de comparar os picos dos testes entre os grupos. Métodos: Foram avaliados 27 indivíduos do sexo masculino, sendo 10 saudáveis (Grupo 1 - G1, 66 +- 5,8 anos) e 17 com DPOC (obstrução moderada a grave, Grupo 2 - G; 71,5 +- 6,3 anos), através de um sistema metabólico, modelo VO2000, operado via computador pelo software Aerograph, para análise das variáveis VO2 e Ve. A SpO2 foi verificada através de um oxímetro de pulso portátil, durante o TD6 e TC6, com intervalo de 30 minutos entre eles. Estudo realizado com a anuência dos pacientes, de acordo com a resolução 196/96 do CNS. Resultados: Com relação a VE, constatou-se diferença significativa (Wilcoxon, p<_0,05) na análise intergupos, verificando-se valores maiores no G2, comparado ao G1; entretanto, o VO2 não mostrou diferença significativamente menor no G2 comparado ao G1 ewm ambos os testes. Na análise intragrupo, o G2 mostrou diferença significativa (Wilcoxon, p<_0,05) apenas para VE, sendo que o TC6 apresentou valores maiores que o TD6. Quanto ao G1, não observou-se diferença significativa ao comparar as variáveis citadas, em ambos os testes. Conclusão: Conclui-se que os indivíduos com DPOC, comparados aos saudáveis, apresentaram maior gasto ventilatório e dessaturação de oxigênio (queda >_5%) em ambos os testes.
