Filter by:The overarching goal of this study is to develop and evaluate a telephone delivered behavioral change intervention for older Veterans with chronic low back pain (cLBP) and comorbid depression, and to ultimately assess its effect on cLBP-related pain, depressive symptoms, and disability. Investigators will conduct a pilot randomized controlled trial to assess feasibility for older Veterans with cLBP and depression assigned to receive the behavioral interventions (n=25) versus waitlist control (n=25). For participants assigned to the intervention arm, trained health coaches will deliver the intervention via telephone. All participants, regardless of what group they have been assigned to will undergo several outcome assessments (pre-screening, baseline, mid-point, final assessments) conducted by a blinded research assistant. Subjects randomized to the waitlist control group will be offered the same intervention once the active intervention group has completed the active sessions and assessments.
This study aims to determine the feasibility and acceptability of conducting a larger randomized clinical trial to test whether individuals with MCI can benefit from mental training programs.
It is proposed to establish a group of subjects composed of 10 healthy individuals of> 50 years and <65, physically active, without metabolic or inflammatory pathology. All of them will undergo a health examination and the physical condition and the absence of contraindication of the sports practice will be characterized through a monitored effort test. Each subject will take a capsule of coenzyme Q10® INDENA for 30 days. The dose to be administered is 100 mg/d of CoQ10 a with food (noon). The state of physical condition and the biochemical and biological variables that reflect oxidative stress and mitochondrial functioning before and after the intervention will be measured.
This project will modify a program that reduces pneumonia among nursing home residents with dementia, so that it is appropriate for assisted living residents with dementia. The program provides daily mouth care to reduce bacteria in the mouth that lead to aspiration pneumonia. The project will develop methods that can be taught to assisted living providers by community dental hygienists, and that are ready for evaluation in a pragmatic trial of AL residents with dementia and the staff who provide their care.
This study focuses on whether high cardiorespiratory fitness in older adults has a protective effect on the vascular response to acute inflammation in comparison to low-fit older and young adults.
The proposed studies will assess 1) the mechanisms for the age-related increase in fatigability during dynamic exercise (Aims 1 and 2) and 2) the effectiveness of high-velocity resistance training coupled with blood flow restriction (BFR) in improving muscle power output and fatigability in older adults (Aim 3). The first two aims are cross-sectional studies comparing young (18-35 years old) and older adults (≥60 yrs old) to test our central hypothesis that the greater accumulation of metabolites and increase in fatigability in older adults is due to either age-related impairments in skeletal muscle bioenergetics (Aim 1) and/or vascular dysfunction (Aim 2). These two aims will integrate techniques to assess whole-muscle bioenergetics (31P-MRS) and in vivo vascular function (near infrared spectroscopy; NIRS and doppler ultrasonography) with in vitro assessment of single fiber bioenergetics (epifluorescence microscopy) and vasoreactivity of isolated skeletal muscle arterioles (video microscopy). We will then determine whether bioenergetics, vascular function and fatigability are altered in older men and women in response to 8 weeks of resistance exercise training of the lower limb both with and without blood flow restriction (Aim 3).
Introduction The promotion of physical activity among older adults is considered to be one of the main actions that can result in more successful aging. Currently, there are few studies focusing on the effects of long-duration physical activity interventions in older adults. Thus, the purpose of the following study was to analyze the effects of an 8-month multicomponent intervention program on cardiorespiratory capacity, body composition, and strength in a group of nonagenarians. A secondary objective was to determine if the impact of the program differed according to the participants' way of life (institutionalized vs. community dwelling). Methods Participants Participants in this research represent a subset from an ongoing study aimed at collecting baseline and follow-up data over three years, to evaluate the health-related changes observed in a cohort of older adults f The present research was carried out on the basis of data obtained from the individuals in this sample who participated in a multicomponent intervention program offered to the inhabitants of the said region and who met the following inclusion criteria: a) being ninety years of age or older; and b) holding a medical certificate confirming their suitability for sport. The exclusion criteria were a) lack of independent ambulation (walking with an assistive device); b) recent upper or lower limb injuries; c) neurological or orthopedic diagnosis in upper or lower-extremities. Intervention A multicomponent intervention program was developed consisting of two 60-minute sessions per week, held on non-consecutive days, for a period of 8 months. The sessions consisted of a warm-up phase (10') in which individuals performed joint mobility exercises and walked at a rate of 3 km/h. Afterwards, muscular strength work was carried out on the upper and lower limbs, including calisthenic exercises, and the use of dumbbells or medicine balls (1-3kg). Generally, the exercises were organized in two sets of 10-15 repetitions, resting for two minutes between sets. Communal ball games and relay games were then practiced (over a distance of 30 meters). Finally, 10 minutes were devoted to relaxation and stretching exercises. multicomponent intervention program was designed and monitored by a specialist in gerontogymnastics. Evaluations Two weeks before the start and after the end of the exercise program, a series of assessments were carried out, which were monitored by specialists in physical exercise and sport, who did not know whether those evaluated were institutionalized or not. Body composition Weight was measured to the nearest 0.1 kg using a Tefal digital scale (type PP1200VO) with the participants wearing light clothing and no shoes. Height was measured to the nearest millimeter with a field stadiometer (Seca 220). The body mass index (BMI) was calculated taking the body weight in kilograms and dividing it by the height in meters squared (BMI: kg/m2). Densitometry Bone mineral density content (BMD) of the femoral neck was measured using a dual energy X-ray absorptiometry (DEXA) machine (Hologic QDR 1000®), which reported BMD in grams per square centimeter (g/cm2). This method was used to ensure better reproducibility, a lower radiation dose and better image resolution (Watts 2004). The minimum significant alteration, with a 95% confidence interval, was 4.7%. Muscular strength Upper limb muscle strength was assessed with the Handgrip Test (HG) on the right hand using a dynamometer (SH5001, SAEHAN Corporation, South Korea). For each measurement, patients were asked to perform their maximum voluntary contraction for 5s. Each measurement was repeated three times with patients resting for 30s between trials. The best performance was recorded for further analysis. Lower limb muscle strength was assessed with the Isometric Knee Extension Test (KNEE), performed three times on the right leg with participants seated on a custom-built chair with a load cell (Vetek VZ101BS, Vaddo, Sweden). For each measurement, participants were asked to perform their maximum voluntary contraction for 5 s. The test was repeated 3 times and participants rested for 2 min between trials. The best performance from the three trials was considered for further analysis. Cardiorespiratory fitness In order to assess the effect of the program on the participants' cardiorespiratory fitness, the six-minute walk test (6MWT), was performed, following standard procedure. The subjects were instructed to walk at their own pace from one end to the other of a 100-foot-long measured distance in an enclosed, level, corridor, and to cover as much ground as possible in 6 min. They were allowed to stop and rest during the test, but were instructed to resume walking as soon as they felt able to do so.
A third of people over 65, and half of people over 80, fall at least once a year. Falls are the most common cause of death from injury in the over 65s and result in a significant financial burden on the whole society. Shoes directly influence balance, gait, and the subsequent risk of slips, trips and falls by altering somatosensory feedback to the foot and ankle. Minimal shoes, that is shoes lacking a firm heel cup, a rigid sole or longitudinal arch support, have shown advantages in strengthening muscles and improving balance as compared to conventional shoes. However, limited research has studied the effect of minimal shoe in older people at risk of falls. The aim of the project will be to assess the effects of minimal shoes in older people at risk of falls, compared to conventional shoes and barefoot.
The proposed research applies the highly innovative technology of real-time functional Magnetic Resonance Imaging (rtfMRI) to examine plasticity of brain-regulatory mechanisms related to cognitive and affective processing and to determine benefits for cognition and affect in young and older adults and in Parkinson Disease (PD) patients.
