In the Eyes of Those Who Were Randomized: Perceptions of Disadvantaged Older Adults in a Tai Chi Trial.

Background And Objectives: Older adults living in subsidized housing have typically been excluded from exercise intervention studies. We conducted a qualitative study to explore the perceived physical, psychological, social, and economic factors that influenced participation in and adherence to a year-long Tai Chi intervention within an ongoing cluster-randomized controlled trial (RCT) for older adults living within subsidized housing facilities.

Research Design And Methods: Focus groups were held with participants of the RCT who were allocated to the trial's Tai Chi intervention.

The Mind Body-Wellness in Supportive Housing (Mi-WiSH) study: Design and rationale of a cluster randomized controlled trial of Tai Chi in senior housing.

Supporting the health of growing numbers of frail older adults living in subsidized housing requires interventions that can combat frailty, improve residents' functional abilities, and reduce their health care costs. Tai Chi is an increasingly popular multimodal mind-body exercise that incorporates physical, cognitive, social, and meditative components in the same activity and offers a promising intervention for ameliorating many of the conditions that lead to poor health and excessive health care utilization. The Mind Body-Wellness in Supportive Housing (Mi-WiSH) study is an ongoing two-arm cluster randomized, attention-controlled trial designed to examine the impact of Tai Chi on functional indicators of health and health care utilization.

Functional implications of muscle co-contraction during gait in advanced age.

Older adults often exhibit high levels of lower extremity muscle co-contraction, which may be the cause or effect of age-related impairments in gait and associated falls. Normal gait requires intact executive function and thus can be slowed by challenging executive resources available to the neuromuscular system through the performance of a dual task. We therefore investigated associations between lower limb co-contraction and gait characteristics under normal and dual task conditions in healthy older adults (85.

Functional benefits of tai chi training in senior housing facilities.

Objectives: To determine the effects of tai chi training on functional performance and walking with and without the addition of the performance of a cognitive task, in older adults living in supportive housing facilities.

Design: Secondary data analysis comparing a single-blind, randomized controlled trial of tai chi training with an attention-matched educational control intervention with crossover to tai chi.

Setting: Two supportive housing facilities.

Optimizing the tracking of falls in studies of older participants: comparison of quarterly telephone recall with monthly falls calendars in the MOBILIZE Boston Study.

Tracking falls among elders is challenging. In this reliability study, which took place between October 2007 and February 2008, the authors compared participants' daily recordings of falls on calendars with a telephone survey of recall of falls over the previous 3 months within the population-based MOBILIZE Boston Study cohort, a cohort of 765 elders. From the cohort, 218 participants were randomly selected.

Issues in conducting epidemiologic research among elders: lessons from the MOBILIZE Boston Study.

Conducting research in elderly populations is important, but challenging. In this paper, the authors describe specific challenges that have arisen and solutions that have been used in carrying out The MOBILIZE Boston Study, a community-based, prospective cohort study in Massachusetts focusing on falls among 765 participants aged 70 years or older enrolled during 2005-2007. To recruit older individuals, face-to-face interactions are more effective than less personal approaches.
