Effects of square stepping exercise in patients with sequel of cerebrovascular accident

Abstract

Introduction: Cerebral stroke is the interruption of blood flow to the brain and can be classified into hemorrhagic and ischemic. It may result in serious body balance and cognition complications. Kinesiotherapy is a privileged means of rehabilitation. Objective: Verify the effects of Square Stepping Exercise (SSE) on cognitive functions, depressive symptoms and the body balance of cerebral stroke sequel patients. Methods: Thirteen brain stroke sequel patients were divided into two groups: SSE (SSEG n = 8) and conventional physiotherapy group (PG, n = 5). The SSEG participated only of the SSE training protocol, while the PG participated of its physical therapy routine group, both for 4 months. They were evaluated using the Mini Mental State Examination (MMSE), the Brief Cognitive Screening Battery (BBRC), the Geriatric Depression Scale (GDS), Berg Balance Scale (BBS) and Timed Up and Go (TUG). Results: The U Mann Whitney test showed no significant differences between groups. In intragroup analysis, the Wilcoxon test showed significant improvement in global cognitive status for PG (p < 0.042), and for SSEG there were positive results for verbal fluency (p < 0.04) and in TUG for number of steps (p<0, 04) and the time (p < 0.02). Conclusion: The SSE seems to benefit dynamic balance, influencing gait agility, cognition related to verbal fluency and may have contributed to maintain other cognitive functions.

Physical exercise and vascular endothelial growth factor (VEGF) in elderly: A systematic review.

Abstract

The aim of this study was to conduct a systematic review of studies that verified the effects of physical exercise on vascular endothelial growth factor (VEGF) in elderly.

METHODOLOGY:

The bibliographic search was conducted in five database, from 1990 to 2013, with the following keywords and boolean operators: physical exercise OR physical exercise OR physical therapy OR exercise OR training AND VEGF OR vascular endothelial growth factor AND aged OR older OR elderly. The inclusion criteria were: (1) sample including elderly with average age of 60; (2) studies that verified the effects of acute exercise; (3) studies that verified the effects of chronic physical exercise; (4) studies with humans; (5) randomized controlled trials, randomized non-controlled trials, non-randomized controlled trials, non-randomized and non-controlled trials; (6) assessment of VEGF peripheral concentrations.

RESULTS:

Ten studies were selected, and that four of them verified an increase of VEGF concentrations after practicing physical exercise and six studies did not verify any change on VEGF concentrations.

CONCLUSION:

Different populations found in this study and the different exercise protocols applied in the studies of this review make it difficult to establish parameters of what would be the best type of exercise to promote an increase on the concentrations of VEGF in the elderly. Therefore, we suggest that further studies can be performed, so that we can establish some recommendations for this population.

Resumo:
Studies indicate the involvement of brain-derived neurotrophic factor (BDNF) in the pathogenesis of Alzheimer’s disease (AD). Decreased BDNF levels may constitute a lack of trophic support and contribute to cognitive impairment in AD. The benefits of acute and chronic physical exercise on BDNF levels are well-documented in humans, however, exercise effects on BDNF levels have not been analyzed in older adults with AD. The aim of this study was to investigate the effects of acute aerobic exercise on BDNF levels in older adults with AD and to verify associations among BDNF levels, aerobic fitness, and level of physical activity. Using a controlled design, twenty-one patients with AD (76.3 ± 6.2 years) and eighteen health older adults (74.6 ± 4.7 years) completed an acute aerobic exercise. The outcomes included measures of BDNF plasma levels, aerobic fitness (treadmill grade, time to exhaustion, VO2, and maximal lactate) and level of physical activity (Baecke Questionnaire Modified for the Elderly). The independent t-test shows differences between groups with respect to the BDNF plasma levels at baseline (p = 0.04; t = 4.53; df = 37). In two-way ANOVA, a significant effect of time was found (p = 0.001; F = 13.63; df = 37), the aerobic exercise significantly increased BDNF plasma levels in AD patients and healthy controls. A significant correlation (p = 0.04; r = 0.33) was found between BDNF levels and the level of physical activity. The results of our study suggest that aerobic exercise increases BDNF plasma levels in patients with AD and healthy controls. In addition to that, BDNF levels had association with level of physical activity.

Effect of a multimodal exercise program on sleep disturbances and instrumental activities of daily living performance on Parkinson’s and Alzheimer’s disease patients.

Resumo:

AIM:

To assess the contribution of a multimodal exercise program on the sleep disturbances (SD) and on the performance of instrumental activities daily living (IADL) in patients with clinical diagnosis of Alzheimer’s disease (AD) and Parkinson’s disease patients (PD).

METHODS:

A total of 42 consecutive patients (23 training group, 19 control group) with PD and 35 demented patients with AD (19 trained group, 16 control group) were recruited. Participants in both training groups carried out three 1-h sessions per week of a multimodal exercise program for 6 months. The Pfeffer Questionnaire for Instrumental Activities and the Mini-Sleep Questionnaire were used to assess the effects of the program on IADL and SD respectively.

RESULTS:

Two-way ancova showed interactions in IADL and SD. Significant improvements were observed for these variables in both intervention groups, and maintenance or worsening was observed in control groups. The analysis of effect size showed these improvements.

CONCLUSION:

The present study results show that a mild to moderate intensity of multimodal physical exercises carried out on a regular basis over 6 months can contribute to reducing IADL deficits and attenuating SD. Geriatr Gerontol Int 2013; ●●: ●●-●●.
