Filter by:The latest randomized controlled trials and systematic reviews of resistance training performed by older adults reported that the systematic use of exercise in machines improves muscle strength and power, functional abilities, body mass and body balance. However, the effect of resistance training with elastic tubes exercises have not been studied in all the variables described above. The objective of this study is to analyze the effects of elastic tubes exercises on muscle mass, muscle strength, functional performance and postural control in elderly untrained.
The immune system is the part of the body that protects against infection. The immune system often doesn't work as effectively as people get older. This research is being done to find out how the immune systems in older people who are over age 75 respond to influenza vaccine (flu shot). We also want to find out if chronic cytomegalovirus (CMV) infection, a common virus infection in older persons affects the immune response in people older than 75 years of age who receive a flu shot. The Flu Shot is a vaccine approved for the prevention of influenza ("Flu") infections and is recommended every year for all persons 50 years and older. People who are older than 75 years of age are considered healthy or frail may join. A total of 1025 persons will be participating in this study. In order to determine if you are qualified for the study, we would ask you to answer a few questions over the phone that will take approximately 5 minutes. If you qualify and agree to proceed, you will be asked to come to Johns Hopkins Bayview Medical Center or, if you are unable to come to Bayview, one of our staff can visit you at your home. During that visit we obtain consent, review your medical history, and measure your vital signs, walking speed and grip strength. We will also administer a few brief questionnaires and collect urine and blood samples. We will then give you the Influenza vaccine for free. 7 days post receiving your Influenza Vaccine we will collect a small blood sample for further immune system testing. also, you will be asked to complete a 12-question survey which will assess your symptoms over the past 7 days (post receiving the Influenza vaccine). Also 4 weeks post receiving your Influenza vaccine you will be asked to complete a third visit that will include follow up health questionnaires and an influenza symptoms assessment questionnaire and vital signs. A third blood draw will be collected (approximately 10 teaspoons) to measure immune responses to the influenza vaccine. In addition, you will receive your test result (CBC/w/Diff.) from visit #1. Throughout the influenza study season, we will call you once a week to ask about your general health and any Flu-like symptoms. These calls will be made throughout the Flu season which typically lasts through May. If you begin to have any influenza like symptoms at any time during the study, we ask that you call our office to report these symptoms so that we may perform vital signs, nasal swab to confirm influenza, and a fourth blood draw to look at the immune response and protection of influenza vaccine.
A 12-week multicomponent exercise is effective in improving executive function and gait performance in dual-task conditions.
As the aging population increases, preventing and decreasing disabilities become a critical issue for the health care system. Previous researches have shown that preventive community-based nursing services for older adults could achieve important health benefits at a relatively low cost. However, many frail and pre-frail older adults living in communities cannot get enough attention from current health care system. The role and function of nurses should be expanded to provide more comprehensive family-oriented care to improve health outcomes of older adults in Taiwan. The objectives of this study are: 1. Understand the difficulties and solutions for nurses providing community-based services in order to expand their better role and function. 2. Develop a cultural sensitive community advanced nurse service model for Taiwan in health care system. 3. Explore the effectiveness of community health programs by nurses for frail or pre-frail older adults in community. Focus groups and literature review will be used to achieve the first and second study objectives. A single centre randomized controlled trial will be used in this study to achieve the third study objective. Two hundred and twenty people aged 65 and over who meet the Fried definition of frailty and pre-frailty will be recruited from the clinic of a hospital. Participants will be followed for a 6-month period. Frailty, quality of life, satisfaction to the services, hospitalizations and admissions to nursing care facilities will be measured and compared between experimental group and control group. This research is an important step in the examination of a new approach to the community older people by nurses. The study results will provide the evidence data to recommendation for related policy making in the future.
WiiNWALK is a 4 week physical activity, with the intervention of a WiiFit, targeted to improve walking capacity in individuals with either a unilateral below-knee or above-knee amputation. This is a randomized control trial to evaluate the effectiveness of the WiiNWALK program in older (50+ years) community living adults with lower limb amputations (LLA). Hypothesis: We expect the WiiNWALK intervention will have a treatment effect with improvement in functional walking capacity, compared to the control group who will only be playing cognitive games. Secondarily, a functional walking capacity will also include an improvement in lower extremity strength and balance, inter-limb gait symmetry, balance confidence along with participation in daily and social activities, locomotor capabilities and an increase in physical activities.
The goal of this study is to evaluate the hypothesis that the addition of liraglutide, a long-acting glucagon-like peptide 1 (GLP-1) analogue, to a calorie-restricted diet will lead to greater weight loss than will a calorie-restricted diet alone in subjects who are older (50 to 60 years of age), overweight/obese, and prediabetic. These individuals have been selected for study because they are at greatly increased risk to develop type 2 diabetes (2DM) and cardiovascular disease (CVD), and it is hypothesized that the addition of liraglutide to a calorie-restricted diet will significantly decrease risk of these adverse outcomes. There is considerable evidence that GLP-I compounds, including liraglutide, improve glycemic control in patients with manifest 2DM. However, there is relatively little information as to the potential utility of these compounds in nondiabetic individual at greatly increased risk of 2DM and CVD. This research proposal is aimed at providing some of this information by quantifying the effects of liraglutide, a long-acting GLP-1 analogue, on weight loss, insulin secretion, insulin action, and multiple CVD risk factors in a very high risk group—older, overweight/obese, prediabetic individuals. Furthermore, by using specific methods, not surrogate estimates, and avoiding the confounding effects of glucotoxicity, it will be possible to gain new insights into the effects of GLP-1 on insulin secretion and insulin action.
The purpose of this interview study is to learn why adults would join a walking program. This study involves interviews with persons who are 65 years of age or older. The interview takes approximately 25 minutes. A total of 132 people will be enrolled. This study will examine the utility or value of various potential features of an incentive-based walking program. These data will enable us to monitor and improve upon enrollment of incentive-based walking programs.
Many individuals with mobility limitations, especially those who are older and have more severe impairments, use a combination of assistive devices and personal assistance to meet their needs. Assistive technology (AT), which includes devices such as wheelchairs, walkers, bathroom grab bars, and dressing aids, helps facilitate day-to-day activities and social participation (basic and instrumental activities of daily living) among these individuals and may decrease their dependence on human assistance. Although some research has reported beneficial outcomes of AT use, few studies have used controlled experimental designs. Furthermore, the results are often difficult to interpret because the AT interventions are only vaguely described. Another concern is that many individuals receive help from others, but scant attention has been paid to the impact of AT on caregivers. This neglect produces an incomplete portrayal of the effect of AT interventions. The proposed study addresses these deficiencies by evaluating the effects of a formalized dyadic AT intervention on individuals with mobility limitations and on their caregivers. The Assistive Technology Provision, Updating and Training (ATPUT)intervention involves a detailed in-home assessment of participants' current AT; the negotiation and implementation of a personal AT plan with the participants and their caregivers; and the provision of AT devices, non-structural home modifications, and device training. Objectives: 1. To determine the efficacy of the Assistive Technology Provision, Updating and Training intervention for assistance users and for their caregivers. 2. To explore how the intervention is experienced by these individuals and to help explain the study findings. General Hypotheses: The investigators anticipate this intervention will increase the daily activities and social participation of individuals with mobility limitations; decrease the psychological and physical demands on caregivers; and reduce the amount of caregiving required. Methodologies: This research will use a combination of quantitative and qualitative methods. The quantitative portion will be an experimental, single-blinded study in which the investigators randomly assign participants to either the ATPUT or a customary care group.
The purpose of the present study is to evaluate the validity of 2 objective measures of physical activity among older adults. In addition, the investigators will examine the influence of functionality, walking aids, walking speed and step length on the accuracy.
Aging is associated with declines in aerobic capacity, exercise tolerance, and functional endurance that lead to physical disability and loss of independence. Furthermore, the existing high prevalence of obesity in the elderly is greatly exacerbating these aging-related declines in function. To date, regular exercise is the only known therapy to consistently improve aerobic function, and perhaps delay the onset of disability. Although aerobic exercise training does benefit both aerobic capacity and endurance even in obese persons, some data show that the maximal efficacy of exercise for improving aerobic function is blunted by obesity. In addition, our preliminary data show a potential dose-response benefit of concomitant fat loss on exercise-induced improvements in aerobic function. Thus, combining an exercise intervention with caloric restriction resulting in fat loss may be more efficacious for improving aerobic function than exercise alone in obese elderly, a population at high risk for disability. The purpose of this study is to determine whether the amount of fat loss (achieved through controlled underfeeding) affects the magnitude of improvement in aerobic function (maximal aerobic capacity and endurance) in response to a standardized exercise training stimulus that follows current recommendations for older persons.
