Accumulating evidence supports that more pain, whether measured by number of pain sites or pain severity, is associated with poorer cognitive function and mobility, and fall risk in older persons. Tai Chi which holistically integrates physical and cognitive functions offers the possibility not only of alleviating pain but also improving attention and mobility in the many older adults who have chronic multisite pain. This proposed full-size randomized controlled Tai Chi trial is a direct extension of the investigators' previous work examining chronic pain, attention demands, mobility and falls in the older population, and is built on the investigators' National Institute on Aging-supported Tai Chi feasibility and acceptability pilot studies among older adults with multisite pain and risk for falls. The goal of this single-blinded randomized controlled trial is to examine the effects of a 24-week Tai Chi intervention on chronic pain, cognition, mobility, fear of falling, and fall rate in older adults with multisite pain and at risk for falls. The results of this study will provide a foundation to establish the clinical significance of Tai Chi in the management of chronic multisite pain and to explore the mechanisms through which Tai Chi improves chronic pain symptoms and lowers fall rate in at-risk older adults.
The investigators will measure pain severity, pain interference, and fear of falling at baseline, mid-point (3-month), and post-intervention (6-month), as well as rate of falls during the intervention (0- to 6-month) and the 6-month follow-up period (month 6 to month 12) in 266 older adults (Tai Chi: N=133, and light physical exercise control: N=133). In addition, they will measure pain-related biomarkers, cognition, single-task and dual-task gait function, free-living physical activity, and sleep at baseline and post-intervention. The primary aims are: 1. to examine the effects of Tai Chi on pain symptoms in older adults with multisite pain. It is hypothesized that older adults in the Tai Chi intervention will have less pain, measured as pain severity and interference, than those in the light physical exercise control group; 2. to examine the effects of Tai Chi on fear of falling and rate of falls in older adults with multisite pain. It is hypothesized that older adults in the Tai Chi intervention will have less fear of falling and fewer falls than those in the light physical exercise control group. The secondary/exploratory aims are: 3. to examine the effects of Tai Chi on pain-related biomarkers in older adults with multisite pain. It is hypothesized that Tai Chi intervention will have greater reductions in levels of pain-related biomarkers and and beta endorphin, than those in the light physical exercise control group; 4. to examine the roles of changes in pain symptoms in the change of fall rate by Tai Chi in older adults with multisite pain. It is hypothesized that the effect of Tai Chi on the reduced fall rate will be explained in part by improvements in pain symptoms in older adults with multisite pain; 5. to examine the roles of changes in cognition and cognitive motor function in the change of fall rate by Tai Chi in older adults with multisite pain. It is hypothesized that the reduced fall rate in the Tai Chi group will be mediated by changes in cognition and cognitive-motor function in older adults with multisite pain.

| Light physical exercise | Behavioral | One hour each session, two sessions each week, for 6 months. Each session will be structured into three 15-minute segments (including warm-up activities/balance exercise/walking, upper and lower body strength exercise/walking, and stretching exercise/balance exercise/walking, respectively), each ending with a short break to record the Borg Rating of Perceived Exertion (RPE), followed by a 5-minute break time or cool-down/wrap-up session. The session will be taught by a certified exercise physiologist and a research assistant. |
