Filter by:Moderate (50-69%) asymptomatic carotid artery stenosis (ACAS) is an important and under-appreciated contributor to balance and mobility dysfunction. This is significant because declines in balance and mobility are a significant predictor of falls, disability, loss of independence, and death in older adults. Further, falls and fall-related injuries in older adults cost approximately 50 billion dollars annually in the United States, and are the leading cause of adverse events reported by the Veterans Health Administration. This proposal seeks to: 1) investigate the impact of a supervised aerobic and challenging balance exercise program on balance and mobility function in patients with moderate ACAS; and 2) elucidate whether these changes are related to changes in cerebral perfusion. With 830,000 Veterans estimated to have moderate ACAS and at risk for balance and mobility dysfunction and increased falls, the findings from this study could have significant impacts on the clinical management, quality of life, and functional independence of Veterans with moderate ACAS.
This study examines the feasibility of an individualized video game training (VITAAL Exergame) for older adults with mobility impairments and/or urinary incontinence. In addition, the effect of the newly developed training program on motor and cognitive functions is examined. This study is a national study. The development of the exergame was carried out at the Fraunhofer AICOS research center in Portugal and further studies are being conducted in international collaboration with the University of Montréal in Canada, KU Leuven in Belgium and ETH Zurich. The Exergame consists of a video game based training, which is performed with step movements. These movements are detected by two sensors on the feet. The video game should make the training fun and motivate to train. The training will include specific cognitive and physical functions. Special emphasis will be put on a continuous interaction and integration of motor and cognitive functions. An intact cognitive-motor interaction as well as balance and strength form the basis for all everyday performances, especially for safe and accident-free movement in older adults. In the Exergame VITAAL, balance is trained with step-based games. Strength, especially leg strength, is trained through Tai-Chi-like movements/exercises. The pelvic floor training takes place using a vaginal probe that measures the contractions of the pelvic floor. The training games on the VITAAL Exergame have been adapted for this purpose and are controlled via the probe. All participants receive an individually tailored training session that is optimally adapted to their needs based on the results of the pre-measurement. Participants with urinary incontinence also receive an integrated pelvic floor training. The study includes 32-52 seniors with mobility impairments and 8-28 older adults with urinary incontinence. Balance and strength, gait pattern, cognitive functions and pelvic floor specific functions will be measured before and after the training in order to detect any changes. The training should be carried out during 12 weeks, with a maximum of two weeks break/holidays. There are two measurement dates with all examinations, whereby one measurement date lasts approx. 1.5 hours. All study participants can continue their everyday life as usual.
30 Veterans who are full-time wheelchair users will use personalized modular cushions for two weeks each. Personalized cushions will be created using a cushion fitting process the investigators have already developed and tested. Microenvironmental conditions will be monitored during use. A cost analysis will ensure the customized modular cushion applies value-driven principles. User satisfaction will be measured along with the effects on daily function, skin status and seated tissue health.
