Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The proposed study will determine whether Tai Chi is an effective and practical intervention to improve overall function and lower health care utilization in an expensive, vulnerable population of seniors that is more representative of many US communities than those previously studied. If the results are favorable, our study will also provide the necessary training and protocol manuals to replicate Tai Chi programs in senior housing facilities across the nation to help prevent, better manage, and overcome frailty among seniors.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Elderly people living in low-income housing facilities represent one of our nation's largest, most functionally impaired, economically disadvantaged, and understudied populations that account for a disproportionate share of Medicare spending. This trial aims to test whether Tai Chi exercises improve the health and reduce the health care utilization of this population more than health education and social calls by conducting a cluster randomized controlled trial in 16 housing facilities in cities surrounding Boston. The proposal builds upon previously successful studies by Drs. Lipsitz, Wayne, and others showing multiple benefits of Tai Chi exercises in elderly people with a variety of diseases and disabilities. A randomized, controlled pilot study showed that 12 weeks of Tai Chi exercises tailored to the abilities of frail seniors living in supportive housing facilities can improve balance, gait, and physical function. The proposed study aims are to determine the effects of Tai Chi exercises conducted at least twice weekly over a 6-month period on 1) functional performance measured by the Short Physical Performance Battery and 2) health care utilization determined from self-reported emergency room visits and hospitalizations in poor, multiethnic, elderly residents of low income housing facilities. Secondary outcomes will include person-centered measures such as physical function, cognition, psychological well-being, falls, and self-efficacy. We hypothesize that compared to the control intervention, Tai Chi will significantly improve physical function and reduce health care utilization. This study will prepare the necessary training and protocol manuals for widespread dissemination of Tai Chi programs in housing facilities across the nation. It will also provide estimates of potential Medicare cost savings that can be used to justify future health insurance payments for this intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Tai Chi

This arm will receive a 6-month Tai Chi training intervention. Tai Chi training will include gentle dynamic stretching and strengthening, slow integrated movements, efficient posture, heightened body awareness and inner focus, active relaxation of body and mind, mindful diaphragmatic breathing, and healing imagery and intention. Participants will be asked to complete two formal group classes each week for at least 6 months, led by senior Tai Chi instructors. Additionally, participants will be given practice Digital Versatile Disc (DVD), DVD players if necessary, and instructions for daily home practice a minimum of 20 minutes on 3 non-class days each week.

Group Type EXPERIMENTAL

Tai Chi training

Intervention Type BEHAVIORAL

Educational Control

This arm will receive a 6-month educational control intervention. Participants will attend monthly educational group sessions within a common area of each housing facility. Sessions will be led by research personnel and include material from Patient Education Forms (PEFs) produced by the American Geriatric Society. Sessions will be semi-structured and contain approximately 30 minutes of lecture and 30 minutes of group discussion.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* able to understand instructions in English
* able to participate safely in Tai Chi exercises at least twice a week
* expected to remain in the facility for 1 year
* are fee-for-service Medicare Beneficiaries for the 3 study years
* Able to stand/walk independently, without the help of another person

Exclusion Criteria

* enrolled in a Program of All-Inclusive Care for the Elderly (PACE), or a Special Needs Plan, since this would make it difficult to isolate the effects of Tai Chi on health care utilization.
* Practice of Tai Chi for \>3 years over lifetime, or more than weekly in prior 6 months
* any unstable or terminal illness (e.g., unstable cardiovascular disease, active cancer, unstable chronic obstructive pulmonary disease (COPD), advanced dementia, psychosis)
* inability to maintain posture sitting or standing
* inability to hear, see, or understand Tai Chi instructions and assessment questions.
