Association Between Depression Symptoms and Disability Outcomes in Older Adults at Risk of Mobility Decline.

Objective: To assess the association between depression symptoms and physical functioning and participation in daily life over 2 years in older adults at risk of mobility decline. Design: A secondary analysis of 2-year observational data from the Boston Rehabilitative Impairment Study of the Elderly. Setting: Nine primary care clinics within a single health care system. Participants: Participants (N=432; mean age ± SD, 76.6±7.0y; range, 65-96y; 67.7% women) were community-dwelling adults (>65y) at risk of mobility decline. Interventions: Not applicable. Main Outcome Measures: Secondary data analyses of the Late Life Function and Disability Instrument (primary outcome), Short Physical Performance Battery (secondary outcome), and Patient Health Questionnaire-9 (PHQ-9) (predictor). Measures were administered at baseline, 12 months, and 24 months. Participants completed a self-report survey asking about 16 medical comorbidities, and demographic information was collected at baseline. Results: Participants had an average ± SD PHQ-9 score of 1.3±3.1, ranging from 0 to 24 at baseline. Twenty-nine percent of participants reported a history of depression. Greater depression symptoms were associated with lower physical functioning (unstandardized beta [B]=-0.14, SE=0.05, P=.011) and restricted participation (frequency subscale: B=-0.21, SE=0.11, P=.001; limitation subscale: B=-0.45, SE=0.04, P<.001) cross-sectionally over 2 years. PHQ-9 was not significantly associated with the rate of change in Late Life Function and Disability Instrument score over 2 years. Conclusions: Treating depression in primary care may be an important strategy for reducing the burden of functional limitations and participation restrictions at any 1 time. Further research is needed on treatment models to cotarget depression and physical functioning among at-risk older adults.

Feasibility and Preliminary Efficacy of Virtual Rehabilitation for Middle and Older Aged Veterans With Mobility Limitations: A Pilot Study.

Objective: To evaluate the feasibility and preliminary efficacy of the transition of an outpatient center-based rehabilitation program for middle and older aged Veterans with mobility limitations to a tele-health platform. Design: Non-randomized non-controlled pilot study including 10 treatment sessions over 8 weeks and assessments at baseline, 8, 16, and 24 weeks. Setting: VA Boston Healthcare System ambulatory care between August 2020 and March 2021. Participants: Veterans aged 50 years and older (n=178) were contacted via letter to participate, and 21 enrolled in the study. Intervention: Participants had virtual intervention sessions with a physical therapist who addressed impairments linked to mobility decline and a coaching program promoting exercise adherence. Main Outcome Measures: Ambulatory Measure for Post-Acute Care (AM-PAC), Phone-FITT, and Self-Efficacy for Exercise (SEE) scale. Results: Completers (n=14, mean age 74.9 years, 86% men) averaged 9.8 out of 10 visits. Changes in the Ambulatory Measure for Post-Acute Care (AM-PAC) exceeded clinically meaningful change after 8 and 24 weeks of treatment, at 4.1 units and 4.3 units respectively. Statistically significant improvements from baseline in AM-PAC and Phone-FITT were observed after 8 weeks of treatment and at 24 weeks. No significant changes were observed in exercise self-efficacy. Conclusions: In this group of veterans, telerehab was feasible and demonstrated preliminary efficacy in both mobility and physical activity, thus justifying further investigation in a larger scale clinical trial.

Early clinical and quality impacts of the Age-Friendly Health System in a Veterans Affairs skilled nursing facility.

BACKGROUND: Skilled nursing facilities (SNFs) are an ideal setting to implement the Age-Friendly Health System (AFHS) approach, an initiative by the Institute for Healthcare Improvement (IHI) centered on the 4Ms: what matters, mobility, mentation, and medication. AFHS implementation has not been well studied in SNFs. METHODS: A 112-bed VA SNF implemented a facility-wide AFHS initiative including the following: (1) participating in a national IHI Age-Friendly Action Community; (2) establishing an AFHS workgroup centered on the 4Ms; (3) identifying meaningful clinical tools and frameworks for capturing each M; and (4) developing sustainment methods. Clinical (life-sustaining treatment, falls, disruptive behaviors, and medication deprescribing) and quality outcomes (rehospitalization, emergency department utilization, and discharge to the community) in addition to patient satisfaction were compared pre- and post-AFHS implementation (bed days of care [BDOC] 17413) to post-implementation (BDOC 20880). RESULTS: Clinical outcomes demonstrated improvements in the 4Ms, including: (1) what matters: 14% increase in life-sustaining treatment documentation (82%-96%; p < 0.01); (2) mobility: reduction in fall rate by 34% (8.15 falls/1000 BDOC to 5.41; p < 0.01); (3) mentation: decrease in disruptive behavior reporting system (DBRS) by 62% (5.11 DBRS/1000 BDOC to 1.96; p = 0.04); (4) medications: 53% increase in average potentially inappropriate medications (PIMs) deprescribing (0.38-0.80 interventions/patient; p < 0.01). Quality outcomes improved including rehospitalization (25.6%-17.9%) and emergency department utilization (5.3%-2.8%) within 30 days of admission. Patient satisfaction scores improved from a mean of 77.2 (n = 31, scale 1-100) to 81.3 (n = 42). CONCLUSIONS: Implementation of the AFHS initiative in a SNF was associated with improved clinical and quality outcomes and patient satisfaction. We describe here a sustainable, interprofessional approach to implementing the AFHS in a SNF.

Primary care barriers and facilitators to nonpharmacologic treatments for low back pain: A qualitative pilot study.

BACKGROUND: Clinical practice guidelines encourage primary care providers (PCPs) to recommend nonpharmacologic treatment as first-line therapy for low back pain (LBP). However, the determinants of nonpharmacologic treatment use for LBP in primary care remain unclear, particularly in low-income settings. OBJECTIVE: To pilot a framework-informed interview guide and codebook to explore determinants of nonpharmacologic treatment use in primary care. METHODS: In this qualitative interview study, we enrolled PCPs and community health workers (CHWs) from four primary care clinics at a safety net hospital. A semistructured interview guide informed by the Consolidated Framework for Implementation Research (CFIR) guided inquiry on barriers/facilitators to nonpharmacologic treatments for LBP (eg, acupuncture, chiropractic care, physical therapy). We included questions on whether current CHW roles may address barriers to nonpharmacologic treatment use. Interviews were audio-recorded, transcribed verbatim, and independently coded by four investigators. An a priori codebook composed of CFIR determinants and known CHW roles guided deductive content analysis to identify major themes. RESULTS: Eight individuals (six PCPs, two CHWs; age range: 32-51 years, five female) participated in hour-long interviews. Half had worked at the hospital for ≥15 years and all reported seeing patients with LBP (range: 2-20 patients per week). All participants identified the following CFIR factors as barriers/facilitators: nonpharmacologic treatment characteristics (perceived cost, relative advantage compared to other treatments); outer setting (patient needs/resources, limited connections with community-based nonpharmacologic treatment) and PCP characteristics (attitudes/beliefs about nonpharmacologic treatments). Although participants indicated several CHW roles could be adapted to address barriers (eg, care coordination, resource linking, case management), other roles seemed less feasible (eg, targeted health education) in our health care system. CONCLUSIONS: Preliminary insight on key determinants of nonpharmacologic treatments for LBP should be further examined in large multisite studies. Future studies may also determine whether a CHW-led strategy can improve nonpharmacologic treatment access and clinical outcomes in primary care.

Research Protocol Adaptations During the COVID-19 Pandemic: A Process Evaluation.

In general, COVID-19-related adaptations that transitioned in-person assessments and interventions to a virtual format were not routinely evaluated. We aimed to conduct a process evaluation to examine the impact of COVID-19-related adaptations on a behavior change intervention designed to increase exercise adherence among Veterans with mobility difficulty. We used secondary data from a nonrandomized study to complete a process evaluation examining the intervention's reach, recruitment, fidelity, dose delivered by physical therapists, and the dose received by the 14 participating Veterans. The physical therapist delivered 95% (133/140) of the study's 10 sessions. Sessions with the lowest delivery dose included Sessions 1 and 10 (86%; n = 12/14). The elements with the lowest dose received included using an exercise journal and developing a postintervention plan (86%; n = 12/14). Our COVID-19 adaptations allowed us to provide our intervention to the majority (67%) of eligible participants without a negative impact on fidelity, dose delivered, or dose received.

Trends in Chiropractic Care and Physical Rehabilitation Use Among Adults with Low Back Pain in the United States, 2002 to 2018.

BACKGROUND: While nonpharmacologic treatments are increasingly endorsed as first-line therapy for low back pain (LBP) in clinical practice guidelines, it is unclear if use of these treatments is increasing or equitable. OBJECTIVE: Examine national trends in chiropractic care and physical rehabilitation (occupational/physical therapy (OT/PT)) use among adults with LBP. DESIGN/SETTING: Serial cross-sectional analysis of the National Health Interview Survey, 2002 to 2018. PARTICIPANTS: 146,087 adults reporting LBP in prior 3 months. METHODS: We evaluated the association of survey year with chiropractic care or OT/PT use in prior 12 months. Logistic regression with multilevel linear splines was used to determine if chiropractic care or OT/PT use increased after the introduction of clinical guidelines. We also examined trends in use by age, sex, race, and ethnicity. When trends were similar over time, we present differences by these demographic characteristics as unadjusted ORs using data from all respondents. RESULTS: Between 2002 and 2018, less than one-third of adults with LBP reported use of either chiropractic care or OT/PT. Rates did not change until 2016 when uptake increased with the introduction of clinical guidelines (2016-2018 vs 2002-2015, OR = 1.15; 95% CI: 1.10-1.19). Trends did not differ significantly by sex, race, or ethnicity (p for interactions > 0.05). Racial and ethnic disparities in chiropractic care or OT/PT use were identified and persisted over time. For example, compared to non-Hispanic adults, either chiropractic care or OT/PT use was lower among Hispanic adults (combined OR = 0.62, 95% CI: 0.65-0.73). By contrast, compared to White adults, Black adults had similar OT/PT use (OR = 0.98; 95% CI: 0.94-1.03) but lower for chiropractic care use (OR = 0.50; 95% CI: 0.47-0.53). CONCLUSIONS: Although use of chiropractic care or OT/PT for LBP increased after the introduction of clinical guidelines in 2016, only about a third of US adults with LBP reported using these services between 2016 and 2018 and disparities in use have not improved.

Defining Clinically Meaningful Cut Points for Leg Power Impairment Using Physical Performance in Older Adults: A Secondary Analysis From Boston RISE.

OBJECTIVE: To identify clinically meaningful thresholds of leg power impairment identified by the stair climb power test (SCPT). DESIGN: Cross-sectional analysis using the baseline data from an observational cohort study. SETTING: The Boston Rehabilitative Impairment Study of the Elderly. PARTICIPANTS: Community-dwelling older adults (N=413). MAIN OUTCOME MEASURES: SCPT and the Short Physical Performance Battery (SPPB). RESULTS: Using the receiver operating characteristic curves and Youden's J statistics, the optimal threshold for the SCPT associated with mobility limitation as defined by an SPPB score ≤9 was 3.07 Watts/kg for men with a sensitivity of 74%, a specificity of 73% and, an area under the curve (AUC) value of 0.78. For women, the optimal threshold was 2.59 Watts/kg with a sensitivity of 83%, a specificity of 69%, and an AUC value of 0.81. The classification and regression tree sensitivity analysis demonstrated similar thresholds, 2.88 Watts/kg and 2.53 Watts/kg for men and women, respectively. CONCLUSIONS: The study identified clinically meaningful thresholds of impairment for the SCPT for mobility limited older primary care patients. These thresholds may be used to inform rehabilitation care to improve functional mobility of older adults and should be validated in larger more representative clinical trials.

Frailty and Time at Home After Post-Acute Care in Skilled Nursing Facilities.

OBJECTIVES: To examine the association of a claims-based frailty index with time at home, defined as the number of days alive and spent out of hospital or skilled nursing facility (SNF). DESIGN: Cohort Study. SETTING AND PARTICIPANTS: A 5% Medicare random sample of fee-for-service beneficiaries, who had continuous part A and B enrollment in the prior 6 months, that were discharged from a short SNF admission in 2014‒2016. METHODS: Frailty was measured with a validated claims-based frailty index (CFI) (range: 0‒1, higher scores indicating worse frailty) and categorized into nonfrail (CFI <0.25), mild frailty (CFI 0.25‒0.34), and moderate-to-severe frailty (CFI ≥0.35). We measured home time in the 6 months following SNF discharge (range: 0‒182 days with higher values representing more days at home and thus a better outcome). We used logistic regression to assess the association between frailty and short home time, defined as <173 days, adjusting for age, sex, race, region, a comorbidity index, clinical SNF admission characteristics in the Minimum Data Set, and SNF characteristics. RESULTS: In our sample of 144,708 beneficiaries (mean age, 80.8 years, 64.9% female, 85.9% white) who were discharged to community after SNF stay, the mean CFI was 0.26 (standard deviation, 0.07). The mean home time was 165.6 (38.1) days in nonfrail, 154.4 (47.4) days in mild frailty, 145.0 (52.0) days in moderate-to-severe frailty group. After full model adjustments, moderate to severe frailty was associated with a 1.71 (95% CI 1.65‒1.78) higher odds of having short time at home in the 6 months following SNF discharge. CONCLUSION AND IMPLICATIONS: Higher CFI is associated with short time at home in Medicare beneficiaries who are discharged to the community after post-acute SNF stay. Our results support the utility of CFI in identifying SNF patients who need additional resources and interventions to prevent health decline and poor quality of life.

Prevalence and Predictors of Ambulatory Care Physicians' Documentation of Mobility Limitations in Older Adults.

OBJECTIVE: To determine how often physicians document mobility limitations in visits with older adults, and which patient, physician, and practice characteristics associate with documented mobility limitations. DESIGN: We completed a cross-sectional analysis of National Ambulatory Medical Care Surveys, years 2012-2016. Multivariate analyses were conducted to identify patient, physician, and practice-level factors associated with mobility limitation documentation. SETTING: Ambulatory care visits. PARTICIPANTS: We analyzed visits with adults 65 years and older. Final sample size represented 1.3 billion weighted visits. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE: We defined the presence/absence of a mobility limitation by whether any International Classification of Diseases (ICD)-9 or ICD-10 code related to mobility limitations, injury codes, or the patient's "reasons for visit" were documented in the visits. RESULTS: The overall prevalence of mobility limitation documentation was 2.4%. The most common codes were falls-related. Patient-level factors more likely to be associated with mobility limitation documentation were visits by individuals over 85 years of age, relative to 65-69 years, (odds ratio 2.32, 95% confidence interval 1.76-3.07]; with a comorbid diagnosis of arthritis (odds ratio 1.35, 1.18-2.01); and with a comorbid diagnosis of cerebrovascular disease (odds ratio 1.60, 1.13-2.26). Patient-level factors less likely to be associated with mobility limitation documentation were visits by men (odds ratio 0.80, 0.64-0.99); individuals with a cancer diagnosis (odds ratio 0.76, 0.58-0.99); and by individuals seeking care for a chronic problem (relative to a new problem [odds ratio 0.36, 0.29-0.44]). Physician-level factors associated with an increased likelihood of mobility limitation documentation were visits to neurologists (odds ratios 4.48, 2.41-8.32) and orthopedists (odds ratio 2.67, 1.49-4.79) compared with primary care physicians. At the practice-level, mobility documentation varied based on the percentage of practice revenue from Medicare. CONCLUSIONS: Mobility limitations are under-documented and may be primarily captured when changes in function are overt.

Changes in Mild Neurocognitive Disorder Status in Mobility Limited Older Primary Care Patients: Implications for Rehabilitative Care.

OBJECTIVE: The aim of the study is to identify potential rehabilitative treatment targets associated with participants' annual cognitive status. DESIGN: A cohort study patients with self-reported mobility limitation who completed neuropsychological, physical performance testing, and questionnaires at baseline to 2-year follow-up were categorized into three groups (persistently cognitively normal, nonpersistent mild neurocognitive disorder, and persistently mild neurocognitive disorder) based on their annual cognitive status using baseline, years 1 and 2 performance on Hopkins Verbal Learning, Trail Making, and Digit Symbol Substitution Tests. Repeated measures multinomial regression analysis was used to examine the differences between groups and associated characteristics. RESULTS: Study included 349 participants (mean age, 76 ± 7) with 57% of participants were persistently cognitively normal, 16% persistently mild neurocognitive disorder, and 27% nonpersistent mild neurocognitive disorder over 2 yrs of follow-up. Faster gait speed (relative risk reduction, 0.64-0.89) was associated with risk reduction and increase in depressive symptoms (relative risk reduction, 1.09-1.12) was associated with greater risk of being classified into the nonpersistent or persistently mild neurocognitive disorder compared with persistently cognitively normal. CONCLUSIONS: Variability across cognitive status over time was observed. Gait speed and depressive symptoms were modifiable risk factors associated with nonpersistent and persistent mild neurocognitive disorder status. This study reinforces the potential benefit of multifaceted rehabilitation for preventing and treating older adults with mobility and/or cognitive problems.

An innovative rehabilitation program for the veterans affairs post-acute skilled nursing setting: Preliminary results.

BACKGROUND: Skilled nursing rehabilitative care plays a critical role in older adults' functional recovery impacting post-discharge outcomes. Variations across post-acute rehabilitative care services and patient outcomes indicate a need to improve rehabilitative care in this setting. We adapted a successful outpatient care program (Live Long Walk Strong-LLWS) to address this need in post-acute care settings within the Veterans Health Administration. LLWS differs from standard PT care by treating impairments linked to functional decline that are not traditionally targeted by standard care, providing formalized coaching to optimize behavior change, and providing post-discharge case management to optimize long-term outcomes. The purpose was to adapt, refine and implement the LLWS program for the Community Living Center (CLC), determine its acceptability and feasibility, and evaluate its preliminary effectiveness among older adults. METHODS: The design of the program was adapted from the original outpatient LLWS program to the CLC setting through quality improvement methods and the Replicating Effective Programs (REP) framework. Primary outcomes included measures of feasibility and acceptability of >80% enrollment and completion of sessions as well as preliminary effectiveness using performance-based and patient-reported measures of function including the Short Physical Performance Battery (SPPB), AM-PAC, a Global Rating of Change questionnaire, and a satisfaction survey. RESULTS: After 18 months, 51 Veterans had enrolled in the LLWS program, with 94.1% maintaining enrollment. We observed >80% completion of the inpatient and home follow-up sessions. Most patients were highly satisfied with care. Improvements in the SPPB (2.3 (SD 2.2) points), gait speed (0.17 (0.14) m/s) and the AM-PAC (6.5 (SD 5.7)) surpassed clinically meaningful thresholds. CONCLUSIONS: This novel care program is feasible and acceptable to Veterans, demonstrating preliminary effectiveness with improving functional outcomes. Future research is needed to further examine the program's impact on other important outcomes relative to standard modes of care.

Age-related changes in gait biomechanics and their impact on the metabolic cost of walking: Report from a National Institute on Aging workshop.

Changes in old age that contribute to the complex issue of an increased metabolic cost of walking (mass-specific energy cost per unit distance traveled) in older adults appear to center at least in part on changes in gait biomechanics. However, age-related changes in energy metabolism, neuromuscular function and connective tissue properties also likely contribute to this problem, of which the consequences are poor mobility and increased risk of inactivity-related disease and disability. The U.S. National Institute on Aging convened a workshop in September 2021 with an interdisciplinary group of scientists to address the gaps in research related to the mechanisms and consequences of changes in mobility in old age. The goal of the workshop was to identify promising ways to move the field forward toward improving gait performance, decreasing energy cost, and enhancing mobility for older adults. This report summarizes the workshop and brings multidisciplinary insight into the known and potential causes and consequences of age-related changes in gait biomechanics. We highlight how gait mechanics and energy cost change with aging, the potential neuromuscular mechanisms and role of connective tissue in these changes, and cutting-edge interventions and technologies that may be used to measure and improve gait and mobility in older adults. Key gaps in the literature that warrant targeted research in the future are identified and discussed.

Mild Neurocognitive Disorder, Social Engagement, and Falls Among Older Primary Care Patients.

OBJECTIVES: (1) To estimate the association between social engagement (SE) and falls; (2) To examine the relation between mild neurocognitive disorder (MNCD) and falls by different levels of SE. DESIGN: We performed a secondary data analysis using prospective cohort study design. SETTING: Primary care. PARTICIPANTS: A total of 425 older adult primary care patients at risk for mobility decline (N=425). As previously reported, at baseline, 42% of participants exhibit MNCD. MAIN OUTCOME MEASURES: The outcome variable was the number of falls during 2 years of follow-up. Exposure variables at baseline included (1) MNCD identified using a cut-off of 1.5 SD below the age-adjusted mean on at least 2 measures within a cognitive performance battery and (2) SE, which was assessed using the social component of the Late-Life Function and Disability Instrument. High SE was defined as having a score ≥ median value (≥49 out of 100). All models were adjusted for age, sex, education, marital status, comorbidities, and pain status. RESULTS: Over 2 years of follow-up, 48% of participants fell at least once. MNCD was associated with a higher rate of falls, adjusting for the covariates (Incidence Rate Ratio=1.6, 95% confidence interval: 1.1-2.3). There was no significant association between MNCD and the rate of falls among people with high SE. In participants with low SE (having a score less than 49.5 out 100), MNCD was associated with a higher rate of falls as compared with participants with no neurocognitive disorder (No-NCD). CONCLUSIONS: Among participants with low SE, MNCD was associated with a higher rate of falls, but not among participants with high SE. The findings suggest that high SE may be protective against falls among older primary care patients with MNCD.

Incorporating Physical Activity Assessments and Behavior Change Techniques Into Geriatrics.

Ninety-one percent of adults 65 years and older do not perform the recommended levels of physical activity (PA), resulting in increased risk of disability, morbidity, and mortality. Despite knowing the benefits of PA and acknowledging the importance of assessing and addressing inadequate PA levels, 50%-75% of health care providers do not incorporate behavior change techniques into clinical practice. This clinical gap can be explained by a lack of knowledge or confidence in (1) assessing PA levels; (2) addressing inadequate PA levels; and (3) justifying the time needed to use these techniques in clinical practice. In this special communication, we address this gap by providing a 3-step theoretical-based clinical decision pathway that guides health care providers on how to identify older adults with inadequate PA levels, determine readiness to increase PA, and empower patents to develop an action plan that will increase their PA levels. We also provide a conceptual model that supports the use of techniques that assess and address inadequate PA by tying PA to the Age-Friendly Health System's 4Ms (ie, What Matters to the older adult, Mentation, Mobility, and Medications).

The Impact of Care Partners on the Mobility of Older Adults Receiving Hemodialysis.

Rationale & Objective: Many older adults receiving hemodialysis have mobility limitations and rely on care partners, yet data are sparse regarding the support provided by care partners. Our aim was to examine how care partners support the mobility of an older adult receiving hemodialysis. Study Design: Qualitative study. Setting & Participants: Using purposive sampling, we recruited persons aged 60 years or more receiving maintenance hemodialysis and care partners aged 18 years or more who were providing support to an older adult receiving hemodialysis. We conducted in-person semi-structured interviews about mobility with each individual. Analytical Approach: We conducted descriptive and focused coding of interview transcripts and employed thematic analysis. Our outcome was to describe perceived mobility supports provided by care partners using qualitative themes. Results: We enrolled 31 older adults receiving hemodialysis (42% women, 68% Black) with a mean age of 73 ± 8 years and a mean dialysis duration of 4.6 ± 3.5 years. Of these, 87% of patients used assistive devices and 90% had care partners. We enrolled 12 care partners (75% women, 33% Black) with a mean age of 54 ± 16 years. From our patient and care partner interviews, we found three themes: (1) what care partners see, (2) what care partners do, and (3) what care partners feel. Regarding what they see, care partners witness a decline in patient mobility. Regarding what they do, care partners guide and facilitate activities and manage others who also assist. Regarding what they feel, care partners respect the patient's autonomy but experience frustration and worry about the patient's future mobility. Limitations: Modest sample size; single geographic area. Conclusions: In older adults receiving hemodialysis, care partners observe a decline in mobility and provide support for mobility. They respect the patient's autonomy but worry about future mobility losses. Future research should incorporate care partners in interventions that address mobility in older adults receiving hemodialysis.

Development of a Coaching Protocol to Enhance Self-efficacy Within Outpatient Physical Therapy.

Objective: To describe the development of the Specific, Measurable, Action-Oriented, Realistic, and Timed (SMART) Coaching Protocol to increase exercise self-efficacy in middle-aged and older adults participating in Live Long Walk Strong (LLWS) Rehabilitation Program. LLWS Rehabilitation Program is an innovative physical therapist (PT) delivered outpatient intervention for middle- and older-aged adults with slow gait speed. Design: Phase II randomized controlled trial (RCT) with masked outcome assessment. We applied the Knowledge to Action Framework to develop and implement the LLWS SMART Coaching Protocol within an RCT for the LLWS Rehabilitation Program. Data will be collected at baseline and post intervention at 2, 8 and 16 weeks. Setting: Outpatient; VA Boston Healthcare System. Participants: Community-dwelling veterans (N=198) (older than 50 years) with slow gait speed (<1.0 m/s). Interventions: Participants will be randomized to the LLWS Rehabilitation Program, an 8-week (10-session) PT-delivered intervention, or wait-list control group. Each study visit will introduce a new SMART Coaching module focused on goal setting, exercise adherence, and addressing internal and external barriers to meeting exercise goals. Main Outcome Measures: Primary outcome is gait speed and secondary outcome is the Self-Efficacy for Exercise Scale. Conclusions: Incorporating cognitive behavioral tools in physical therapy intervention research is critical for targeting motivational processes needed for exercise behavior change.

Rehabilitation at the Time of Pandemic: Patient Journey Recommendations.

Purpose: The World Health Organization (WHO) declared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) a pandemic in March 2020, causing almost 3.5 million coronavirus disease (COVID-19) related deaths worldwide. The COVID-19 pandemic has imposed a significant burden on healthcare systems, economies, and social systems in many countries around the world. The access and delivery of rehabilitation care were severely disrupted, and patients have faced several challenges during the COVID-19 outbreak. These challenges include addressing new functional impairments faced by survivors of COVID-19 and infection prevention to avoid the virus spread to healthcare workers and other patients not infected with COVID-19. In this scoping review, we aim to develop rehabilitation recommendations during the COVID-19 pandemic across the continuum of rehabilitation care. Materials and Methods: Established frameworks were used to guide the scoping review methodology. Medline, Embase, Pubmed, CINAHL databases from inception to August 1, 2020, and prominent rehabilitation organizations' websites were searched. Study Selection: We included articles and reports if they were focused on rehabilitation recommendations for COVID-19 survivors or the general population at the time of the COVID-19 pandemic. Data Extraction: Two of our team members used the pre-tested data extraction form to extract data from included full-text articles. The strength and the quality of the extracted recommendations were evaluated by two reviewers using the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. Results: We retrieved 6,468 citations, of which 2,086 were eligible after removing duplicates. We excluded 1,980 citations based on the title and the abstract. Of the screened full-text articles, we included 106 studies. We present recommendations based on the patient journey at the time of the pandemic. We assessed the evidence to be of overall fair quality and strong for the recommendations. Conclusion: We have combined the latest research results and accumulated expert opinions on rehabilitation to develop acute and post-acute rehabilitation recommendations in response to the global COVID-19 pandemic. Further updates are warranted in order to incorporate the emerging evidence into rehabilitation guidelines.

Physical Activity and Physical Activity Participation Barriers Among Adults 50 Years and Older During the COVID-19 Pandemic.

OBJECTIVE: We examined changes in physical activity from pre-COVID-19 to during the COVID-19 pandemic and the factors associated with reduced physical activity levels among adults 50 yrs and older. DESIGN: Participants of a validation study were stratified into being "less active than before" or "equally or more active than before" COVID-19. Multivariable manual backward analyses were used to identify self-reported barriers associated with the reduction in physical activity. RESULTS: Reduced physical activity levels during COVID-19 were reported among 244 of 503 participants (43%). After adjusting for demographics and health conditions, factors that increased the odds of reduced physical activity levels during COVID-19 were lacking access to workout places, feeling too anxious, and difficulty committing to physical activity. Factors that decreased the odds of reduced physical activity levels during COVID-19 were self-identifying a heart- or lung-associated diagnosis that impacts physical activity and having a 12-mo retrospective history of falling. CONCLUSIONS: The physical activity participation barriers identified to be associated with a reduction in physical activity can be used as a starting point for a conversation regarding physical activity participation during COVID-19.

Mobility in Older Adults Receiving Maintenance Hemodialysis: A Qualitative Study.

RATIONALE & OBJECTIVE: For older adults, maintaining mobility is a major priority, especially for those with advanced chronic diseases like kidney failure. However, our understanding of the factors affecting mobility in older adults receiving maintenance hemodialysis is limited. STUDY DESIGN: Descriptive qualitative study. SETTING & PARTICIPANTS: Using purposive sampling, we recruited (1) persons aged≥60 years receiving maintenance hemodialysis; and (2) care partners (≥18 years) providing regular support to an older adult receiving hemodialysis. During a single in-person home visit, we assessed mobility using the Short Physical Performance Battery (SPPB) and conducted individual one-on-one interviews regarding important personal factors related to mobility. ANALYTICAL APPROACH: Descriptive statistics were used for demographic and SPPB data. Transcripts underwent thematic coding, informed by the International Classification of Function framework of mobility. We used conceptual content analysis to inductively extract themes and subthemes. RESULTS: We enrolled 31 older adults receiving hemodialysis (42% female, 68% Black) with a mean age of 73±8 years and mean dialysis vintage of 4.6±3.5 years; their mean SPPB score was 3.6±2.8 points. Among 12 care partners (75% female, 33% Black), the mean age was 54±16 years and mean SPPB score was 10.1±2.4 points. Major themes extracted were (1) mobility represents independence; (2) mobility is precarious; (3) limitations in mobility cause distress; (4) sources of encouragement and motivation are critical; and (5) adaptability is key. LIMITATIONS: Modest sample from single geographic area. CONCLUSIONS: For older adults receiving hemodialysis, mobility is severely limited and is often precarious in nature, causing distress. Older adults receiving hemodialysis and their care partners have identified sources of encouragement and motivation for mobility, and cite an adaptable mindset as important. Future studies should conceptualize mobility as a variable condition and build on this outlook of adaptability in the development of interventions.

Evidence for a Specific Association Between Sustained Attention and Gait Speed in Middle-to-Older-Aged Adults.

Although cognitive decline has previously been associated with mobility limitations and frailty, the relationship between sustained attention and gait speed is incompletely characterized. To better quantify the specificity of the sustained attention and gait speed association, we examined the extent to which this relationship is unique rather than accounted for by executive functioning and physical health characteristics. 58 middle-to-older-aged community-dwelling adults without overt evidence of cognitive impairment (45-90 years old; 21 females) participated in the study. Each participant completed a 4-meter gait speed assessment and validated neuropsychological tests to examine various domains of executive functioning including working memory (i.e., Digit Span), inhibitory control (i.e., D-KEFS Color-Word Interference), and task switching (i.e., D-KEFS Number/Letter Switching). Multiple physical and vascular risk factors were also evaluated. Sustained attention was assessed using the gradual onset continuous performance task (gradCPT), a well-validated go/no-go sustained attention task. A series of linear regression models were used to examine how different aspects of cognition, including sustained attention and traditional measures of executive functioning, related to gait speed while controlling for a variety of physical and vascular risk factors. Among all predictors, gradCPT accuracy explained the most variance in gait speed (R 2 = 0.19, p < 0.001) and was the only significant predictor (ß = 0.35, p = 0.01) when accounting for executive functioning and other physical and vascular risk factors. The present results indicate that sustained attention may be uniquely sensitive and mechanistically linked to mobility limitations in middle-to-older adults.
