Balance and gait improved in patients with MS after physiotherapy based on the Bobath concept

Background and Purpose . Patients with multiple sclerosis (MS) tend to have movement difficulties, and the effect of physiotherapy for this group of patients has been subjected to limited systematic research. In the present study physiotherapy based on the Bobath concept, applied to MS patients with balance and gait problems, was evaluated. The ability of different functional tests to demonstrate change was evaluated. Method . A single‐subject experimental study design with ABAA phases was used, and two patients with relapsing–remitting MS in stable phase were treated. Tests were performed 12 times, three at each phase: A (at baseline); B (during treatment); A (immediately after treatment); and A (after two months). The key feature of treatment was facilitation of postural activity and selective control of movement. Several performance and self‐report measures and interviews were used. Results . After intervention, improved balance was shown by the Berg Balance Scale (BBS) in both patients, and improved quality of gait was indicated by the Rivermead Visual Gait Assessment (RVGA). The patients also reported improved balance and gait function in the interviews and scored their condition as ‘much improved’. Gait parameters, recorded by an electronic walkway, changed, but differently in the two patients. Among the physical performance tests the BBS and the RVGA demonstrated the highest change, while no or minimal change was demonstrated by the Rivermead Mobility Index (RMI) and Ratings of Perceived Exertion (RPE). Conclusion . The findings indicate that balance and gait can be improved after physiotherapy based on the Bobath concept, but this should be further evaluated in larger controlled trials of patients with MS.

对血脂异常人群实施生活方式干预后的观察

目的：探讨生活方式治疗在血脂异常人群中的作用，观察其效果。方法：100例在体检中发现的血脂异常者，随机分为实验组和对照组，对实验组进行生活方式治疗，对照组未进行生活方式治疗，两组均未使用药物降脂，随访6—9个月，平均7．6个月，复查血脂，以检测血脂结果是否达到目标值进行对比。结果：经统计学处理，两组血脂在达到目标值方面存在显著性差异（p〈0．01）。结论：生活方式治疗对血脂异常人群具有明显的防治作用。     

The aging process and potential interventions to extend life expectancy

Aging is commonly defined as the accumulation of diverse deleterious changes occurring in cells and tissues with advancing age that are responsible for the increased risk of disease and death. The major theories of aging are all specific of a particular cause of aging, providing useful and important insights for the understanding of age-related physiological changes. However, a global view of them is needed when debating of a process which is still obscure in some of its aspects. In this context, the search for a single cause of aging has recently been replaced by the view of aging as an extremely complex, multifactorial process. Therefore, the different theories of aging should not be considered as mutually exclusive, but complementary of others in the explanation of some or all the features of the normal aging process. To date, no convincing evidence showing the administration of existing “anti-aging” remedies can slow aging or increase longevity in humans is available. Nevertheless, several studies on animal models have shown that aging rates and life expectancy can be modified. The present review provides an overlook of the most commonly accepted theories of aging, providing current evidence of those interventions aimed at modifying the aging process.     

士兵体能训练卫生规范

以部队装备和士兵体质现状为基础，制定了士兵体能训练卫生规范。《规范》主要规定了以下三部分内容：①部队士兵进行基本体能训练应遵循循序渐进、超负荷训练及适宜恢复等生理卫生要求；耐力、力量和柔韧性训练的方式、强度和时间；体能训练的组织实施等，以使体能训练负荷与机体的生理状态相适应；②体能训练的卫生监督，针对体能训练中可能遇到的医学问题进行监督，能够防止训练伤、过度疲劳及其它医学事故的出现，保障体能训练的顺利进行；③体能训练的医学效果评价。本标准适用于陆军部队士兵基本体能训练。海、空军地勤部队士兵的体能训练亦可参照执行。     

How Can and Do Australian Doctors Promote Physical Activity?

Background.Physical inactivity is recognized as an important public health issue. Yet little is known about doctors' knowledge, attitude, skills, and resources specifically relating to the promotion of physical activity. Our survey assessed the current practice, perceived desirable practice, confidence, and barriers related to the promotion of physical activity in family practice.Methods.A questionnaire was developed and distributed to all 1,228 family practitioners in Perth, Western Australia.Results.We received a 71% response (n= 789). Family practitioners are most likely to recommend walking to sedentary adults to improve fitness and they are aware of the major barriers to patients participating in physical activity. Doctors are less confident at providing specific advice on exercise and may require further skills, knowledge, and experience. Although they promote exercise to patients through verbal advice in the consultation, few use written materials or referral systems.Conclusions.There are significant differences between self-reports of current practice and perceived desirable practice in the promotion of physical activity by doctors. Future strategies need to address the self-efficacy of family physicians and involve resources of proven effectiveness. The potential of referral systems for supporting efforts to increase physical activity by Australians should be explored.     

长期居住海平面后藏族经受急性减压低氧时的体力活动能力

本研究从急性低氧对移居海平面后藏族的体力活动能力的影响来探索藏族的高原低氧适应机制。结果揭示藏族的最大体力负荷强度没有显著下降，最大氧耗和氧脉搏也没有明显变化，动脉血氧饱和度明显高于汉族，这更显示藏族对高原低氧适应机制有独特之处。推测可能是藏族在氧的摄取、传递和释放过程比汉族更有利于对高原低氧环境的适应。     

Physical activity consultation for people with Type 2 diabetes: evidence and guidelines.

Physical activity is an important, but often underused, therapeutic strategy within diabetes care. To date, little is known about the best way to promote physical activity in diabetes care. Physical activity consultation is an intervention designed to promote physical activity behaviour change. This article provides guidelines on how to conduct a physical activity consultation with people who have Type 2 diabetes, and reviews the evidence surrounding the effectiveness of this intervention in this population. The trans-theoretical model is the underlying theory of behaviour change for the physical activity consultation intervention. The review identifies research which supports the use of this model for understanding physical activity behaviour in people with Type 2 diabetes. The review outlines a number of modifiable variables associated with physical activity behaviour change in this population. How each of these variables is addressed within the guidelines for conducting a physical activity consultation is identified. Finally, limited but consistent research highlights the effectiveness of physical activity consultation for promoting physical activity in people with Type 2 diabetes.
