4 Clinical Trials for Various Conditions
In this project, the investigators propose to demonstrate the feasibility of remotely-monitored, caregiver (or spouse)-administered, home-based tES (transcranial electrical stimulation) intervention to improve mobility in ambulatory older adults with recent falls. This is a four-phase feasibility study in older, ambulatory adult participants at risk of falling due to a loss of balance (participant faller, PF) together with a willing and able participant administrator (PA) that is available during weekdays to administer tES to the PF. Phase 1 is focused on the development and refinement of our training materials for home-based tDCS (transcranial direct current stimulation) for PF/PA pairs. The objectives of this phase: 1. Identify areas of confusion and challenges for older adults. 2. Refine our training materials to accompany the home-based tDCS system. In Phase 2, the investigators will complete a pilot trial in 12 PF/PA pairs to assess the feasibility of deploying home-based tES in larger clinical trials, and to prepare for the development and implementation of such trials. The objectives of this phase: 1. Determine the mean/range number of visits needed for in-person training. 2. Compliance and retention with the study protocol. 3. Safety/side effects of home-based tES, as compared to previously established laboratory-based tES data. The investigators hypothesize that adult PAs are able to successfully administer home-based tES to PFs. The investigators also expect that PF/PA pairs will exhibit excellent adherence to the intervention and that the prevalence and severity of reported tDCS side-effects will be similar to that observed in previous laboratory-based studies. In Phase 3, the investigators will complete a pilot trial in up to 18 PF/PA pairs; i.e., those who have previously successfully completed either Phase 1 or Phase 2. The study objectives/aims for Phase 3 are: 1. Further explore compliance and retention with the study protocol over a longer time period 2. Identify safety/side effects of home-based tES over a longer time-period as compared to previously established laboratory-based tDCS interventions. In Phase 3, the investigators hypothesize that adult PA's who have previously demonstrated the ability to successfully administer tES at home, will retain competence and compliance with administration over a longer period, up to 1 year. In Phase 4, we will complete a pilot trial in up to 18 PF/PA teams; those who have previously successfully completed Phase 3. The study objective/aims for Phase 4 will be to: 1. Identify Safety, effectiveness and adherence to home-based tES over longer period of time as compared to previously established laboratory-based tES interventions. 2. Further explore the proof of Concept for the home-based tES interventions In Phase 4 we hypothesize that adult PA's who have previously demonstrated the ability to successfully administer tES at home, will adhere with the study protocol over a longer period of time, up to 3 years.
The overarching objective of this project is to assess the potential public health impact of delivering Tai Ji Quan: Moving for Better Balance, a proven fall prevention program, through local community dissemination partners (e.g., senior service providers), in the selected counties in the state of Oregon.
This clinical trial will compare the effects of a high intensity Resistance Exercise via Negative Work (RENEW) vs. Traditional resistance exercise (TRAD) as part of a mult-component exercise and fall-reduction program on muscle conditioning; falling risks; as well as the fall incidence in older adults who have fallen. We anticipate that muscle conditioning will mediate the effect of RENEW on falling risks and fall incidence.
Older adults may feel at risk for falling, but do not have a physical risk of falling. On the other hand, some older adults may not feel at risk for falling, but do have a physical risk of falling. This study is being done to test a preventative, in-home exercise program (called PEER) which may allow older adults to improve balance, align the perceived risk for falling with the physical risk for falling, and prevent falls. Participants will be asked to participate in this study for approximately 9 months. This study has three specific aims: 1. Examine differences in balance, fall risk, and physical activity after program completion, follow-up 3 months and 6 months between older adults (OAs) in the Physio-fEedback Exercise pRogram (PEER) intervention and OAs in attention control (AC) condition. 2. Explore differences in exercise adherence and the proportion of shifting in fall risk appraisal and negative self-perception on aging after program completion, follow-up 3 months and 6 months between OAs in the PEER intervention and OAs in AC condition. 3. Explore participants' experiences with the PEER intervention and potential barriers to access and adoption of the technology-based PEER intervention to inform future research. Participants will be asked to participate in this study for approximately 9 months. This includes the baseline assessment, 8 weeks of PEER activities or attention control activities, and follow-up assessments at 3 months and 6 months. After the informed consent and completion of the baseline assessments, participants will be randomized to either the PEER intervention or the attention control (AC) group. Participants in the PEER intervention group will be asked to participate in group exercises (60 minutes per week for 8 weeks) and home-based exercises (twice a week for 8 weeks) that focus on balance, strength training with a peer coach. Participants in the AC group will receive an information pamphlet developed by the CDC about falls called Simple Exercises for Improving Balance and Preventing Falls in Older Adults. Topics include information on fall risks, how to prevent falls, how to check for safety, postural hypotension, and chair rise exercises. The control group will be encouraged to discuss fall prevention with a primary care provider and continue normal activities.
