Is Tai Chi beneficial for multisite pain syndrome in older adults?

Chronic musculoskeletal pain is prevalent and undertreated in older adults. In particular, multisite pain is associated with serious functional consequences and falls and appears to be a novel geriatric syndrome. The causes of multisite pain are often multifactorial, and emerging evidence supports a complex pathway whereby multisite pain leads to cognitive problems, mobility decline, fear of falling, falls, and reduced participation in life roles. A few pharmacologic approaches are safe and effective for older adults with chronic multisite pain and evidence for effectiveness of non-pharmacologic treatments for this common condition is very limited. Compared to light physical exercise, mind-body exercise may prove to be more beneficial for older adults living with chronic pain. Tai Chi, as a movement-based mind-body exercise, can relieve pain symptoms, improve cognition and physical function, and lower risk for falls in older adults. However, little is known about the potential benefits of Tai Chi for older adults with multisite pain syndrome. Future large-scale randomized-controlled trials are needed to investigate the effectiveness of Tai Chi in alleviating pain and lowering fall risk in older adults with multisite pain, and the biological mechanisms that underlie its potential benefits to chronic pain, physical and cognitive functions, and falls in this at-risk population.

Pilot studies of recruitment and feasibility of remote Tai Chi in racially diverse older adults with multisite pain.

BACKGROUND: Multisite musculoskeletal pain is highly prevalent among older adults yet undertreated. Studies support the promise of Tai Chi for managing pain and lowering fall risk. Since the COVID-19 pandemic, effective alternatives to classroom-based exercise programming are warranted. AIMS: To recruit 100 racially diverse older adults with multisite pain and increased fall risk, who are interested in participating in a future Tai Chi clinical trial, and to evaluate the feasibility and acceptability of a short-term, remotely delivered home-based Tai Chi program. METHODS: A random sample of adults aged 65 years or older living in diverse Boston neighborhoods were sent mailed invitations to participate in a telephone screening survey. Eligible adults were invited to join a 4-week Tai Chi program offered online via Zoom. Primary outcomes were class attendance, experience, and program safety. RESULTS: Among 334 survey respondents, 105 were eligible for the intervention. Average age of eligible participants was 74 years, 75% were women, and 62% were Black. We assigned 32 participants to 4 Tai Chi or 2 light exercise groups conducted via Zoom; of these, 24 (75%) completed the program and 79% attended ≥6 of 8 classes. There were no adverse events reported. Two-thirds reported it was very easy to join the online classes and 88%, very easy to see the instructor. CONCLUSION: Mailed invitations were effective for recruiting a racially diverse sample. Remote exercise programming delivered online via live Zoom sessions is safe and feasible for diverse older adults who have multisite pain and risk of falls.

Effects of Tai Chi on beta endorphin and inflammatory markers in older adults with chronic pain: an exploratory study.

The purpose of this exploratory study was to examine the effects of Tai Chi on blood levels of beta endorphin (ß-endorphin) and inflammatory markers in older adults with chronic pain. Forty community-dwelling older adults with chronic pain were randomized to Tai Chi or light physical exercise, and each offered twice weekly for 12 weeks. Following the 12-week intervention, neither Tai Chi nor light physical exercise changed levels of ß-endorphin and inflammatory markers. However, in older adults who completed 70% or more classes, Tai Chi significantly lowered levels of ß-endorphin (p < 0.05), whereas light physical exercise did not change levels of ß-endorphin. The results suggest that Tai Chi may reduce levels of ß-endorphin in older adults with chronic pain. Future studies are needed to better understand the role of the opioid analgesic system and immune system in regulating pain with aging and the long-term effects of Tai Chi on pain-related biomarkers.

Tai Chi for older adults with chronic multisite pain: a randomized controlled pilot study.

BACKGROUND: Chronic pain is associated with poorer cognition and mobility, and fall risk in older adults. AIMS: To investigate the feasibility of a randomized controlled trial of mind-body exercise (Tai Chi) versus light physical exercise in older adults with multisite pain. METHODS: Adults aged ≥ 65 years with multisite pain who reported falling in the past year or current use of an assistive device were recruited from Boston area communities. Participants were randomized to either a Tai Chi or a light physical exercise program, offered twice weekly for 12 weeks. The primary outcomes were feasibility and acceptability. Secondary outcomes included pain characteristics, cognition, physical function, gait mobility, fear of falling, and fall rate. RESULTS: Of 176 adults screened, 85 were eligible, and 54 consented and enrolled (average age 75 ± 8 years; 96.30% white; 75.93% female). The dropout rate was 18% for Tai Chi and 12% for light physical exercise. For those completing the study, exercise class attendance rate was 76% for Tai Chi and 82% for light physical exercise. There were no significant group differences in most secondary outcomes. Tai Chi significantly lowered pain severity (4.58 ± 1.73 to 3.73 ± 1.79, p < 0.01) and pain interference (4.20 ± 2.53 to 3.16 ± 2.28, p < 0.05), reduced fear of falling (90.82 ± 9.59 to 96.84 ± 10.67, p < 0.05), and improved several single-task and dual-task gait variables, while light physical exercise did not change these measures. DISCUSSION AND CONCLUSIONS: This study demonstrated the feasibility and acceptability of conducting a larger randomized controlled trial in older adults with multisite pain. Study findings and challenges encountered will inform future research.

Do Patients Who Access Clinical Information on Patient Internet Portals Have More Primary Care Visits?

BACKGROUND: As health care costs alarm the nation and the debate increases about the impact of health information technologies, patients are reviewing their medical records increasingly through secure Internet portals. Important questions remain about the impact of portal use on office visits. OBJECTIVE: To evaluate whether use of patient Internet portals to access records is associated with increased primary care utilization. RESEARCH DESIGN: A prospective cohort study. SUBJECTS: Primary care patients registered on patient Internet portals, within an integrated health system serving rural Pennsylvania and an academic medical center in Boston. MEASURES: Frequency of "clinical portal use" (days/2 mo intervals over 2 y) included secure messaging about clinical issues and viewing laboratory and radiology findings. In year 2, a subset of patients also gained access to their primary care doctor's visit notes. The main outcome was number of primary care office visits. RESULTS: In the first 2 months of the 2-year period, 14% of 44,951 primary care patients engaged in clinical portal use 2 or more days per month, 31% did so 1 day per month, and the remainder had no clinical portal use. Overall, adjusted for age, sex, and chronic conditions, clinical portal use was not associated with subsequent office visits. Fewer than 0.1% of patients engaged in high levels of clinical portal use (31 or more login days in 2 mo) that were associated with 1 or more additional visits in the subsequent 2 months (months 3 and 4). However, the reverse was true: office visits led to subsequent clinical portal use. Similar trends were observed among patients with or without access to visit notes. CONCLUSIONS: Patients turn to their portals following visits, but clinical portal use does not contribute to an increase in primary care visits.

Characteristics of chronic pain associated with sleep difficulty in older adults: the Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly (MOBILIZE) Boston study.

OBJECTIVES: To evaluate pain severity and distribution in relation to sleep difficulty in older adults. DESIGN: Population-based cross-sectional study. SETTING: Community within a 5-mile radius of the study center at the Institute for Aging Research, Hebrew SeniorLife (HSL), Boston. PARTICIPANTS: Seven hundred sixty-five participants of the Maintenance of Balance, Independent Living, Intellect, and Zest in the Elderly (MOBILIZE) Boston Study aged 64 and older. MEASUREMENTS: Pain severity was measured using the Brief Pain Inventory (BPI) Pain Severity Subscale. Musculoskeletal pain distribution was grouped according to no pain, single site, two or more sites, and widespread pain (upper and lower extremities and back pain). Three aspects of sleep difficulty were measured using items from the Center for Epidemiologic Studies Depression Scale, Revised (trouble getting to sleep, sleep more than usual, and restless sleep). RESULTS: Prevalence of trouble getting to sleep according to BPI severity was 17.8%, 19.7%, 32.0%, and 37.0% for the lowest to highest pain severity quartiles, respectively. Similar relationships between pain and sleep were observed across sleep measures according to pain severity and distribution. Adjusted for sociodemographic characteristics, chronic conditions, and health behaviors, chronic pain was strongly associated with trouble sleeping (≥ 1 d/wk) (single-site pain, odds ratio (OR)=1.77, 95% confidence interval (CI)=1.10-2.87; multisite pain, OR=2.38, 95% CI=1.48-3.83; widespread pain, OR=2.55, 95% CI=1.43-4.54, each compared with no pain). Similar associations were observed for restless sleep and sleeping more than usual. For specific pain sites alone or in combination with other sites of pain, only modest associations were observed with sleep problems. CONCLUSION: Widespread or other multisite pain and moderate to severe pain are strongly associated with sleep difficulty in older adults. Further research is needed to better understand the burden and consequences of pain-related sleep problems in older adults.

Risks for frequent antimicrobial-treated infections in postmenopausal women.

BACKGROUND AND AIMS: Infections are a major cause of morbidity and mortality in older adults. Little is known about factors that alter the susceptibility to infection in the older population. This study in postmenopausal women examines health-related conditions and behavioral factors that may increase the risk of frequent infections, defined as having, on average, one or more infections per year. METHODS: A prospective cohort study with 5 years of follow-up was conducted in 1320 women aged 55 to 80 years. The subjects were Group Health Cooperative of Puget Sound (GHC) enrollees screened for a large fracture prevention trial who also participated in a survey of dietary and supplemental vitamin use. The main outcome, total number of infection events per subject, was derived from a new method of identifying outpatient infections based on the antimicrobial prescription fills recorded in GHC automated pharmacy records. RESULTS: Prevalent lung disease (OR = 6.1, 95% CI 2.8-13.4), receiving a prescription for vitamin C (OR = 2.1, 95% CI 1.4-3.4), and the second and third tertiles of the Chronic Disease Score (OR = 1.7, 95% CI 1.1-2.7 and OR = 2.4, 95% CI 1.5-3.9, respectively) were associated with 5 or more antimicrobial-treated infections during follow-up. A body mass index (BMI) of less than 22 kg/m2 (OR = 0.6, 95% CI 0.3-1.0) was suggestive of an association. CONCLUSIONS: The study provides new information on risk factors for outpatient infections and raises new questions regarding the susceptibility to frequent infections in older women. In addition, the automated pharmacy record method used in this study offers a low-cost alternative for use in future epidemiologic research.
