Filter by:This is a pilot randomized control trial with single blinding of the assessor that will be conducted in two nursing homes residence to evaluate the applicability of a physical exercise program performed in an aquatic environment compared with the same realization but land-based to reduce falls in the institutionalized old people. The secondary objectives are to study the applicability of the intervention in improving balance, function, gait mobility, muscle strength of the lower limbs and the perception of the intervention.
The investigator will proceed to assess changes in oxygenation of muscle tissue, electromyographic activation and strength in healthy subjects. For this, a measurement of all demographic variables on the first day of the study as well as a familiarity with the equipment will be performed. Participants will start the intervention 48 hours later to proceed with the first intervention with one of the exercises in this research (inertial pulley or regular machine). Later on, 48 hours later participants will perform the latest intervention that has not yet done, thus generating a crossover study.
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.
Older people tend to live a sedentary lifestyle which causes a loss of cardiorespiratory fitness, impaired postural stability and a increased risk of falls. Social isolation of older people leads to depression and other mental diseases. However, numerous studies show that age-related degradation processes and functional limitations can be counteracted by physical activity. Various studies show that alpine skiing is a complex sport that places demands on the cardiorespiratory, neuromuscular and sensorimotor systems. With studies providing evidence to suggest alpine skiing is an appropriate activity for elderly as a health-enhancing sport, perhaps Alpine skiing could provide the physical activity needed to counteract age-related degradation processes and loss of function. To date, there is a lack of long-term intervention studies devoted to this topic. The aim of this study was to monitor the long-term effects of skiing on the health of older people, as to age-related muscle breakdown, cardiorespiratory fitness, body stability, general mobility and the overall psychological state of the subjects.
This pilot study is designed to analyze the effects of Vibration Therapy (VT) on grip strength and level of forearm contraction by measuring hand grip dynamometry and surface Electromyography (sEMG) using the BioPac sEMG and digital dynamometry devices after the application of both passive and active Vibrational Therapy (VT) using the PowerPlate.
The significance of this population-based study is in producing new information for planning interventions and rehabilitation programs for the elderly, planning education of health care personnel and planning national health education programs for different age groups. The study consists of an epidemiological cross-sectional study and a randomized controlled intervention study. The study population consisted of all the 1689 home-dwelling women born during 1924-1927 residing in Oulu, Northern Finland, who were asked to a screening visit including bone mineral density (BMD) measurement of the distal radius in 1997. 1222 women attended the clinic and were afterwards mailed a postal questionnaire focusing on lifelong risk factors for osteoporosis, e.g. the amount of physical activity at work and during leisure time, daily intake of calcium and use of alcohol and cigarettes. Those with BMD value more than 20% lower than the reference value, underwent a densitometry of the hip. All women with femoral neck BMD more than 20% below the reference value (n=160) were randomly selected to either exercise (n=84) or control (n=76) group. At baseline and after that annually during the 30-month intervention, balance, muscle strength, aerobic capacity, walking speed, cognitive functions and mood are measured from all the participants. Hip BMD will be measured annually. The exercise group participates in a supervised training program with weekly sessions from the beginning of October to the end of April. In addition to the supervised sessions the participants train daily at home. From April to October the exercises are performed purely at home. The training regimen consists of balance, strength and impact exercises. The intervention group keeps diary of their daily physical activity. The number and severity of falls are recorded from both the groups. The purpose of the study is: 1. to identify factors accounting for low BMD in elderly home-dwelling women with severe osteopenia. 2. to evaluate how supervised regular weight-bearing exercise program affects BMD in elderly home-dwelling women with severe osteopenia 3. to evaluate how supervised regular balance and muscle training affects balance and muscle strength in elderly home-dwelling women with severe osteopenia. In addition the aim is to: 4. study how regular supervised exercise affects the incidence and severity of falls, mood and cognitive functions in women with severe osteopenia. Hypothesis and research methods The main hypothesis is that long-term supervised, mainly home- based regular impact-type and balance and muscle exercises can improve balance and muscle strength of lower extremities and maintain bone mass in elderly women. We also hypothesize that the incidence of falls is lower in the exercise group than in the controls and that the falls are more injurious in the control group than in the intervention group during the follow-up period
