Health Outcomes of Tai Chi in Subsidized Senior Housing (Mi-WISH)

February 20, 2020 updated by: Hebrew SeniorLife
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

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.

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: 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.
Behavioral: Tai Chi training
Active Comparator: 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.
Behavioral: Educational Control

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Short Physical Performance Battery (SPPB) Total Score
Time Frame: Change from baseline to 6 months
The Short Physical Performance Battery includes measures of standing balance (timing of tandem, semi-tandem, and side-by-side stands), 4-meter walking speed and the ability and time to rise from a chair 5 times. The minimum score = 0, the maximum score=12. A higher score means a better outcome.
Change from baseline to 6 months
Health Care Utilization
Time Frame: up to 12 months
Health care utilization will be defined by counts of hospitalizations during the study period.
up to 12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Mobility
Time Frame: Change from baseline to 6 months
Mobility will be assessed by the Timed Up-and-Go, which records the time needed to stand from a chair, walk three meters, turn, walk back to the chair and sit down.
Change from baseline to 6 months
Gait Velocity
Time Frame: Change from baseline to 6 months
Gait velocity will be measured in meters/second (m/s) during two conditions: Normal walking (NW) and Dual task(DT) condition (counting backwards by 3's or 1's while walking)
Change from baseline to 6 months
Standing Balance
Time Frame: Change from baseline to 6 months
Standing balance will be assessed by recording 95% ellipse sway area with eyes open in meters squared (m2)
Change from baseline to 6 months
Grip Strength
Time Frame: Change from baseline to 6 months
Grip strength of the dominant hand will be assessed with a hand-grip dynamometer in kilograms (kg).
Change from baseline to 6 months
Self-reported Physical Activity
Time Frame: Change from baseline to 6 months
Self-reported physical activity will be assessed with the Physical Activity Scale for the Elderly (PASE). The range for this scale is 0-400, with higher score representing higher activity score (better outcome).
Change from baseline to 6 months
Executive Function
Time Frame: Change from baseline to 6 months

Executive function will be assessed with the Trail Making Test (TMT). Participants are timed while sequentially connecting a series of numbered circles (TMT part A), as well as connecting an alternating series of numbers and letters (e.g., A-1-B-2-C-3…) (TMT part B).

The outcome measure is the time difference in seconds between Part B and Part A.
Change from baseline to 6 months
Health-related Quality-of-life
Time Frame: Change from baseline to 6 months
Health-related quality-of-life will be assessed with the Short Form-12 (SF-12), which is a 12 item short form survey, a shortened version of the Short Form-36 (SF-36) health survey that is widely-utilized to assess physical and mental health, as well as the outcomes of healthcare services. The total score ranges from 0-100, with a lower score representing a better outcome for *both* the "Physical component" and "Mental Component"
Change from baseline to 6 months
Depression
Time Frame: Change from baseline to 6 months
Depressive symptoms will be assessed with the Center of Epidemiology Studies-Depression Scale Revised (CESD-R). The 20 item CESD-R test score range is between 0-60, with a lower score representing a better outcome.
Change from baseline to 6 months
Exercise Self-efficacy
Time Frame: Change from baseline to 6 months
Exercise self-efficacy will be assessed with a valid and reliable exercise self-efficacy questionnaire (Activities-specific Balance Confidence (ABC) score). The ABC score ranges from 0-100, with a higher score indicating a better outcome.
Change from baseline to 6 months
Falls
Time Frame: 12 months
Falls will be defined as any event in which the participant unintentionally comes to rest on the ground or other lower level, not as a result of a major intrinsic event or an overwhelmingly external hazard. This outcome measure is reporting the sum total number of falls for each intervention.
12 months
Health Care Utilization
Time Frame: Baseline, 6 months and 12 months
Secondary health care utilization outcomes include counts of emergency room visits.
Baseline, 6 months and 12 months
Mini-Mental State Examination
Time Frame: Change from baseline to 12 months
The Mini-Mental State Questionnaire is a 30 point questionnaire that is used extensively to measure cognitive impairment. Total score = 30, score ranges are from 0 to 30. A higher score indicates better performance.
Change from baseline to 12 months
