Development of a Novel Mind-Body Activity and Pain Management Program for Older Adults With Cognitive Decline

Exploring mechanisms of improvement in the Active Brains intervention for older adults with chronic pain and early cognitive decline

OBJECTIVES

We iteratively developed, optimized, and established the feasibility of a virtual, group-based, mind-body activity program (Active Brains, AB), supported by Fitbit for older adults with chronic pain (CP) and early cognitive decline (ECD). Guided by the principles of the NIH stage model we 1) explore signals of improvement in AB outcomes and hypothesized mechanisms of action and 2) explore relationships between changes in outcomes with changes in mechanisms.

METHODS

Participants were N = 15 older adults (age ≥ 60) with CP-ECD from two NIH stage 1 pilot studies of AB. We conducted paired t-tests to explore pre-post improvements, and correlations to investigate associations between changes in outcomes and mechanisms.

RESULTS

We observed small to large improvements across co-primary and secondary outcomes (d = 0.24-1.09). We observed small to medium improvements in 4 out of 5 hypothesized mechanisms (d = 0.23-0.47). Overall, improvements in outcomes had moderate to large associations with improvements in hypothesized mechanisms.

CONCLUSION

AB was associated with improvements across several co-primary and secondary outcomes, and hypothesized mechanisms. Pain-specific coping and general coping skills are promising treatment targets to address the CP-ECD comorbidity among older adults.

Association of Osteoarthritis and Functional Limitations With Cognitive Impairment Among Older Adults in the United States

Objective: Given overlapping pathophysiology, this study sought to assess the association between osteoarthritis (OA), functional impairment, and cognitive impairment in the aging population. Methods: The National Health and Nutrition Examination Survey was used to identify participants >60 years of age. We analyzed multivariable associations of grouped participants that underwent cognitive function testing using linear and logistic regression, adjusting for sex, age, race, and ethnicity. Results: Of 2776 identified participants representing a population of 50,242,917, 40% did not report OA or functional limitations; 21% had OA but not functional limitations; 15% did not have OA but had functional limitations; 17% had OA and related functional limitations; and 7% had OA and non-arthritic functional limitations. OA was not independently associated with cognitive impairment. Contrarily, functional limitations were associated with cognitive impairment regardless of OA diagnosis. Discussion: Cognitive impairment is not associated with OA, but rather functional limitations, potentially guiding future intervention.

Addressing the Chronic Pain-Early Cognitive Decline Comorbidity Among Older Adults: Protocol for the Active Brains Remote Efficacy Trial

BACKGROUND

Chronic pain and early cognitive decline, which are costly to treat and highly prevalent among older adults, commonly co-occur, exacerbate one another over time, and can accelerate the development and progression of Alzheimer disease and related dementias. We developed the first mind-body activity program (Active Brains [AB]) tailored to the needs of older adults with chronic pain and early cognitive decline. Results from our previous study strongly supported the feasibility of conducting AB remotely and provided evidence for improvements in outcomes.

OBJECTIVE

We are conducting a single-blinded, National Institutes of Health stage-2, randomized clinical trial to establish the efficacy of AB versus a time-matched and dose-matched education control (Health Enhancement Program [HEP]) in improving self-reported and objective outcomes of physical, cognitive, and emotional functions in 260 participants. The methodology described in this paper was informed by the lessons learned from the first year of the trial.

METHODS

Participants are identified and recruited through multidisciplinary clinician-referred individuals (eg, pain psychologists and geriatricians), the Rally Research platform, social media, and community partnerships. Interested participants complete eligibility screening and electronic informed consent. Baseline assessments include self-report, performance-based measures (eg, 6-min walk test) and objective measures (eg, Repeatable Battery for the Assessment of Neuropsychological Status). Participants are mailed a wrist-worn ActiGraph device (ActiGraph LLC) to passively monitor objective function (eg, steps) during the week between the baseline assessment and the beginning of the programs, which they continue to wear throughout the programs. After baseline assessments, participants are randomized to either AB or HEP and complete 8 weekly, remote, group sessions with a Massachusetts General Hospital psychologist. The AB group receives a Fitbit (Fitbit Inc) to help reinforce increased activity. Assessments are repeated after the intervention and at the 6-month follow-up. Coprimary outcomes include multimodal physical function (self-report, performance based, and objective). Secondary outcomes are cognitive function (self-report and objective), emotional function, and pain.

RESULTS

We began recruitment in July 2022 and recruited 37 participants across 4 cohorts. Of them, all (n=37, 100%) have completed the baseline assessment, 26 (70%) have completed the posttest assessment, and 9 (24%) are actively enrolled in the intervention (total dropout: n=2, 5%). In the three cohorts (26/37, 70%) that have completed the AB or HEP, 26 (100%) participants completed all 8 group sessions (including minimal makeups), and watch adherence (1937/2072, 93.48%, average across ActiGraph and Fitbit devices) has been excellent. The fourth cohort is ongoing (9/37, 24%), and we plan to complete enrollment by March 2026.

CONCLUSIONS

We aim to establish the efficacy of the AB program over a time-matched and dose-matched control in a live video-based trial and test the mechanisms through theoretically driven mediators and moderators. Findings will inform the development of a future multisite effectiveness-implementation trial.

The Lived Experience of Healthcare Workers in Preventing Falls in Community Dwelling Individuals with Dementia

Older adults living with dementia have at least twice the risk of falling compared to their peers living without cognitive impairment. There is evidence for the effectiveness of standard interventions in falls prevention in community dwellings, but they may not translate to individuals with Mild Cognitive Impairment (MCI) or dementia. A qualitative enquiry, adopting an interpretive research design underpinned by a phenomenological approach using semi-structured interviews with four healthcare workers from the field was adopted. Data were analysed using Interpretive Phenomenological Analysis to identify themes. Four major themes were developed: on-going assessment is important in guiding interventions and influencing change, knowledge and experience informs practice, individuals living with dementia have complex physical and cognitive needs, and teamwork is essential in falls prevention strategies, which highlighted falls prevention in this context being multifactorial and complex. The findings found that combining physical and cognitive strategies as part of falls prevention has potential benefits for this population, including reducing falls risks and maintaining function. Targeted training and awareness raising within a supportive multi-disciplinary team structure is required, underpinned by on-going, person-centred assessments.

My Healthy Brain: a multimodal lifestyle program to promote brain health

BACKGROUND

Promoting brain health depends on sustaining healthy behaviors across the lifespan. Yet, public adoption of lifestyle behaviors and knowledge of cognitive decline (CD) prevention remains poor. Our multidisciplinary team developed My Healthy Brain (MHB) to promote a healthy lifestyle (e.g. diet, exercise, alcohol, sleep) and build cognitive reserve (e.g. memory compensatory strategies). Our objective was to demonstrate early proof-of-concept for MHB by exploring the feasibility, acceptability, and improvement in primary lifestyle outcomes as well as secondary outcomes of self-determination and subjective wellbeing.

MATERIALS AND METHODS

Older adults with subjective (self-report only) or objective (confirmed by cognitive testing) CD, referred by neurologists to modify lifestyle risk factors (e.g. sedentary), participated in a non-randomized open pilot of MHB (N = 24). Participants completed the 8-week MHB group (90 min each) and pre-post outcome measures.

RESULTS

MHB met all a-priori set benchmarks, including good feasibility of recruitment (71% of patients screened) and enrollment (75% completed baseline), and good acceptability of treatment (75% completed 6 of 8 sessions and post-testing). Program satisfaction was excellent (100% of participants) and no adverse events were reported. We also observed improvements in primary lifestyle outcomes as well as secondary outcomes of self-determination and subjective well-being.

DISCUSSION

While MHB demonstrated preliminary feasibility and the potential to modify lifestyle risk factors for CD, the program can be improved. Future work will explore the integration of mindfulness skills with behavioral principles to bolster multidomain lifestyle change, and the live video delivery format to bypass barriers to participation.

Adaptation and virtual feasibility pilot of a mindfulness-based lifestyle program targeting modifiable dementia risk factors in older adults

OBJECTIVES

We developed a group-based program (My Healthy Brain, MHB) to engage older adults at-risk for dementia in healthy lifestyles. We report on a two-part study to adapt MHB by incorporating mindfulness skills, using mobile health technology to monitor and reinforce behaviors, and delivering it via live video.

METHODS

Participants were older adults (age ≥ 60) with subjective cognitive decline (SCD) and at least one lifestyle risk factor. In Aim 1 (n = 11, 2 groups), we conducted focus groups to obtain qualitative feedback on proposed adaptations. In Aim 2 (n = 10), we conducted a virtual open pilot with exit interviews to explore the feasibility and outcomes of the adapted MHB.

RESULTS

Thematic analysis revealed: (1) barriers and facilitators to healthy lifestyles, (2) positive impressions of MHB, (3) interest in mindfulness skills, and (4) openness to study technologies. MHB met a-priori feasibility benchmarks and was associated with improvements in cognition, lifestyle (e.g. physical function), and proposed mechanisms (e.g. mindfulness). Exit interviews confirmed high feasibility and satisfaction.

CONCLUSION

The integration of mindfulness, live video, and mobile health technologies was feasible and promising for improving healthier lifestyles. The results inform the next feasibility RCT of MHB to prepare for efficacy testing.

My Healthy Brain: Rationale and Case Report of a Virtual Group Lifestyle Program Targeting Modifiable Risk Factors for Dementia

Nearly half of dementia cases may be explained by modifiable lifestyle risk factors. Multidomain interventions are needed to bypass cognitive decline (CD) and aging-related barriers to sustained healthy lifestyles in at-risk older adults. We iteratively developed  My Healthy Brain, a group-based lifestyle program (8 weeks, 90 min sessions) delivered via live video that applies behavioral principles to target multiple risk factors for dementia. We describe the program structure, virtual delivery, and outcomes for a group of older adults with subjective CD or mild cognitive impairment and lifestyle risk factors (e.g., sedentary, poor sleep or diet). We also conducted a group exit interview to qualitatively assess participant experiences and elicit feedback to improve My Healthy Brain. This case report demonstrates that delivering evidence-based brain health education and behavior change skills in a group setting via live video is feasible, acceptable, and has the potential to improve lifestyle, cognitive, and psychosocial outcomes in older adults with CD.

Virtual Mind-Body Program for Obese Knee Osteoarthritis Patients with Comorbid Depression: Development and Feasibility Pilot (Preprint)

Background

Knee osteoarthritis (KOA) is the most common joint disorder in the United States and a leading cause of disability. Depression and obesity are highly comorbid with KOA and accelerate knee degeneration and disability through biopsychosocial mechanisms. Mind-body physical activity programs can engage biological, mechanical, and psychological mechanisms to improve outcomes in KOA, but such programs are not currently available.

Objective

This mixed methods study aims to adapt a mind-body activity program for the unique needs of patients with KOA, depression, and obesity (GetActive-OA) delivered via live video.

Methods

Participants were adults (aged ≥45 years) from rural Kentucky with obesity (BMI≥30 kg/m²), idiopathic KOA with mild to moderate radiographic changes, and elevated depressive symptoms (9-item Patient Health Questionnaire ≥10) recruited from 2 orthopedic centers. In phase 1, we developed GetActive-OA and the study protocol using qualitative focus group feedback from the study population (N=9; 2 focus groups, 90 minutes) and multidisciplinary expertise from clinical psychologists and orthopedic researchers. In phase 2, we explored the initial feasibility, credibility, and acceptability of GetActive-OA, live video delivery, and study procedures via an open pilot with exit interviews (N=5; 1 group). This research was guided by National Institutes of Health (NIH) model stage IA.

Results

Phase 1 qualitative analyses revealed nuanced information about challenges with coping and increasing activity, high interest in a mind-body activity program, program participation facilitators (flexibility with technology) and barriers (amotivation and forgetfulness), and perceived challenges with data collection procedures (blood and urine samples and homework). Phase 2 quantitative analyses showed that GetActive-OA met most a priori feasibility markers: acceptability (80%), expectancy (100%), credibility (100%), clinician adherence (90%), homework adherence (80%), questionnaire data collection (100%), program satisfaction (100%), and safety (100%). Adherence to ActiGraph wear (80% baseline, 20% posttest) and collection of blood samples (60%) were low. Participation in GetActive-OA was associated with signals of improvements in general coping (Cohen d=2.41), pain catastrophizing (Cohen d=1.24), depression (Cohen d=0.88), anxiety (Cohen d=0.78), self-efficacy (Cohen d=0.73), pain (Cohen d=0.39), and KOA symptoms (Cohen d=0.36). Qualitative exit interviews confirmed quantitative findings and provided valuable information to optimize the program and protocol.

Conclusions

Patients with KOA, depression, and obesity from rural Kentucky were interested in a live video mind-body activity program. GetActive-OA shows promise; however, the program and protocol require further NIH stage I refinement before formal efficacy testing (NIH model stage II).

Feasibility randomized controlled trial of a mind-body activity program for older adults with chronic pain and cognitive decline: The virtual "Active Brains" study

BACKGROUND AND OBJECTIVES

Chronic pain (CP) and cognitive decline (CD) are highly co-morbid and debilitating among older adults. We iteratively developed Active Brains-Fitbit (AB-F), a group mind-body activity program aided by a Fitbit that is feasible and associated with improvements in physical, cognitive, and emotional functioning when delivered in person to older adults with CP and CD. We adapted our intervention and methodology for remote delivery to bypass barriers to participation. Here we report on a feasibility randomized controlled trial of the virtual AB-F versus a Health Enhancement Program (HEP) educational control followed by qualitative exit interviews.

RESEARCH DESIGN AND METHODS

Older adults (age ≥ 60) with CP and CD (2 cohorts) completed eight weeks of AB-F (n = 8) or HEP (n = 11). Study procedures were fully remote via live video. Quantitative analyses explored feasibility and acceptability markers and within group improvements in outcomes. Qualitative analyses were primarily deductive using the Framework Method.

RESULTS

AB-F met a-priori set feasibility benchmarks, similar to our in-person pilot. Participation in AB-F was associated with preliminary signals of improvement in multimodal physical function, emotional function (anxiety), cognitive function, pain intensity, and coping (e.g., pain self-efficacy, catastrophizing). Participation in HEP was associated with smaller or negligible improvements. Exit interviews confirmed feasibility and satisfaction with our completely remote interventions and methodology.

DISCUSSION AND IMPLICATIONS

Results provide evidence for the feasibility of our completely remote study, and for initial markers of improvement after AB-F. The results will inform a fully powered remote efficacy trial.

Live Video Adaptations to a Mind-Body Activity Program for Chronic Pain and Cognitive Decline: Protocol for the Virtual Active Brains Study

BACKGROUND

Chronic pain (CP) and cognitive decline (CD) are costly, challenging to treat, prevalent among older adults, and worsen each other over time. We are iteratively developing Active Brains-Fitbit (AB-F), a live video program for older adults with CP and CD that teaches mind-body skills and gradual increases in step count. AB-F has demonstrated feasibility; acceptability; and signs of improvement in emotional, physical, and cognitive functions when delivered in person to older adults.

OBJECTIVE

We are conducting a feasibility randomized controlled trial (RCT) of AB-F versus a time- and dose-matched educational control (health enhancement program [HEP]) in older adults with CP and CD. Here, we describe virtual adaptions to our study protocol, manualized treatments, evaluation plan, and study design in response to feedback from former participants and COVID-19. We will evaluate the feasibility benchmarks and the potential of AB-F to improve physical, emotional, and cognitive functions.

METHODS

This is a single-blind pilot RCT. Participants are randomized to AB-F or HEP. Patients are recruited through pain clinic referrals, institutional registries, and flyers. Interested participants are screened for eligibility via telephone and provide electronic informed consent. After randomization, participants are mailed all study documents, including their treatment manual, an ActiGraph accelerometer, and a Fitbit (separate envelope for AB-F only). Both conditions are manualized and delivered over 8 weekly sessions via Zoom. Participants complete self-report and performance-based (6-min walk test and Montreal Cognitive Assessment) outcome measures via Zoom at baseline and post intervention. Primary outcomes are a priori set feasibility (recruitment, quantitative measures, and adherence), acceptability, credibility, expectancy, and satisfaction benchmarks. Secondary outcomes are physical, cognitive, and emotional functions as well as intervention targets (social function, pain intensity, pain-specific coping, and mindfulness).

RESULTS

The trial is ongoing. We have recruited 21 participants (10 AB-F and 11 HEP) across 2 rounds. Only 2 participants have withdrawn (1 before baseline and 1 before the first session). All 19 remaining participants have completed the baseline assessment. In the first round, attendance is high (11 out of 12 participants completed all 4 sessions so far), and AB-F participants are adherent to their Fitbit and step goals (5 out of 6 participants).

CONCLUSIONS

Preliminary findings are promising for the feasibility of our completely virtual AB-F intervention. However, these findings need to be confirmed at the trial conclusion. This study will answer important questions about the feasibility of delivering a completely virtual mind-body activity program to older adults with comorbid CP and CD, which, to our knowledge, is unprecedented. Details on integrating multiple digital platforms for virtual assessments and intervention delivery will inform treatment development for older adults and those with comorbid CP and CD, which is crucial during the COVID-19 pandemic.
