Hatha Yoga effects on Alzheimer patients (AP) / Efeito de um Programa de Hatha Yoga em Pacientes com Alzheimer / Efecto de un programa de Hatha Yoga en pacientes con enfermedad de Alzheimer (EA)

Abstract This study assessed the effect of a Hatha yoga program in 20 men and 41 women diagnosed with Alzheimer's Disease (AD), who showed mild (36%) and moderate (64 %) global cognitive decline and whose average age was 76,9 years old (SD=11,7). The design was quasi-experimental of repeated measures (pre, post and follow-up). The instruments applied were: Alzheimer's Disease Related Quality of Life Scale (ADRQL); Questionnaire of Quality of Life (QQL), Geriatric Depression Scale (YESAVAGE); Mini Mental State Examination (MMSE); memory and processing speed sub-scales of WAIS III test, Trail Making Test (TMT-A); Lawton and Brody Test; and Barthel Test. The yoga program consisted of 32 one hour sessions twice a week Data analysis was conducted using 35 patients who participated throughout the whole study. The post-treatment mean showed a positive improvement tendency in quality of life and attention. However, during the follow-up, these variables mean value was equal to, or even lower, than the one established in the pre-treatment. The repeated measures ANOVA results showed that no significant change occurred between measurements. The content analysis of eight focus groups suggests that, from the perspective of patients and caregivers, positive changes were observed in patients' mood, attention, episodic and procedural memory, and functionality. More studies are necessary with a higher number of patients and sessions per week, as well as a control group, whose function would be to increase validity of the results obtained.

Resumo Neste estudo, avaliou-se o efeito de um programa de hatha yoga em 20 homens e 41 mulheres com idade média de 76.9 anos (DE = 11.7), com diagnóstico de Doença de Alzheimer (DA) que apresentavam deterioração cognitiva global leve (36 %) e moderada (64 %). O desenho foi quase-experimental de medidas repetitivas (pré, pós e seguimento). Utilizaram-se a escala de qualidade de vida para pacientes com Alzheimer (ADRQL, em inglês), o questionário de qualidade de vida (QV), a escala de depressão geriátrica de Yesavage, o Minimental State Examination (MMSE), dois subtestes da escala de inteligência para adultos do WAIS-III (retenção de dígitos e códigos), o Trail Making Test (TMT-A), o teste de Lawton e Brody, e a escala de Barthel (atividades básicas e funcionais). O programa contou com 32 sessões de hatha yoga de uma hora, realizadas duas vezes por semana. A análise de dados foi feita com 35 pacientes que permaneceram até a fase de seguimento. Como resultados, obteve-se que, entre pré-tratamento e pós-tratamento, as variáveis mostraram uma taxa incremental de melhoramento em QV e atenção; contudo, essas melhorias não se mantiveram seis meses depois; o ANOVA de medidas repetidas não mostrou mudanças significativas em nenhuma variável; a análise qualitativa de oito grupos focais com pacientes e cuidadores indicou que estes perceberam mudanças positivas nos pacientes com relação ao seu estado de humor, atenção, memória episódica e procedimental. São necessários mais estudos com maior número de pacientes e sessões de yoga por semana, além de um grupo de controle para melhorar a validade dos resultados.

Effect of yoga exercise therapy on oxidative stress indicators with end-stage renal disease on hemodialysis.

BACKGROUND: Oxidative stress promotes endothelial dysfunction and atherosclerosis in chronic renal disease. OBJECTIVES: This study investigated the impact of Hatha yoga on oxidative stress indicators and oxidant status, in patients with end-stage renal disease (ESRD) on hemodialysis. DESIGN: This prospective randomized study consisted of 33 ESRD patients in the Hatha yoga exercise group who were matched with 35 ESRD patients in the control group. OUTCOME MEASURES: The oxidative stress indicators (malondialdehyde - MDA, protein oxidation - POX, phospholipase A2 - PLA2 activity) and the oxidative status (superoxide dismutase (SOD) and catalase activities) were determined in the blood samples taken at the pre-hemodialysis treatment, at baseline (0 months) and after four months. RESULTS: In patients in the Hatha yoga exercise group, lipid peroxidation, as indicated by MDA decreased by 4.0% after four months (P = 0.096). There was also a significant reduction in the activity of PLA from 2.68 ± 0.02 IU / L to 2.34 IU / L (- 12.7%; P = 0.010) and POX from 2.28 ± 0.02 nmol / mg to 2.22 ± 0.01 nmol / mg (- 22.6%; P = 0.0001). The activity of SOD significantly increased from 12.91 ± 0.17 U / L to 13.54 ± 0.15 U / L (4.65%; P = 0.0001) and catalase from 79.83 ± 0.63 U / L to 80.54 ± 0.80 U / L (0.90%; P = 0.0001). There was a significant correlation between the pre-hemodialysis oxidative stress parameters at the zero month and after four months for the activities of PLA (r = 0.440), catalase (r = 0.872), and SOD (r = 0.775). CONCLUSIONS: These findings suggest that the Hatha yoga exercise has therapeutic, preventative, and protective effects in ESRD subjects, by decreasing oxidative stress.

Effect of exercise therapy on lipid parameters in patients with end-stage renal disease on hemodialysis.

BACKGROUND: Dyslipidemia has been established as a well-known traditional risk factor for cardiovascular disease in chronic kidney disease patients. AIM: This study investigated the impact of Hatha yoga exercise on lipid parameters in patients with end-stage renal disease (ESRD) on hemodialysis. MATERIALS AND METHODS: This prospective randomized study consisted of 33 ESRD patients in the Hatha yoga exercise group that was matched with 35 ESRD patients in the control group. Serum total cholesterol, triglycerides, low-density lipoprotein (LDL)-cholesterol, and high-density lipoprotein (HDL)-cholesterol were determined at baseline (0 month) and after 4 months. RESULTS: Comparing values after 4 months versus baseline in the prehemodialysis Hatha yoga exercise group, there was found a significant decrease in total cholesterol from 5.126 ± 0.092 mmol/l to 4.891 ± 0.072 mmol/l (-4.58%; P = 0.0001), triglycerides from 2.699 ± 0.078 mmol/l to 2.530 ± 0.063 mmol/l (-6.26%; P = 0.0001), LDL-cholesterol from 2.729 ± 0.083 mmol/l to 2.420 ± 0.066 mmol/l (-11.32%; P = 0.0001), and total cholesterol/HDL-cholesterol ratio from 5.593 ± 0.119 mmol/l to 4.907 ± 0.116 mmol/l (-12.26%; P = 0.047). For patients in the Hatha yoga exercise group, 51.5% had normal total cholesterol at 0 month while 70.0% had normal total cholesterol (P < 0.05) after 4 four months and 54.5% of patients had normal LDL-cholesterol at 0 month while 84.9% had normal LDL-cholesterol after 4 months (P < 0.05). CONCLUSION: These findings suggest that Hatha yoga exercise has preventive and beneficial effects and may be a safe therapeutic modality in ESRD patients.
