Physical Therapist and Patient Perspectives on Mobile Technology to Support Home Exercise Prescription for People With Arthritis: A Qualitative Study.

Introduction Mobile applications (apps) for exercise prescription may enhance communication between healthcare providers and patients while addressing common barriers to exercise among people with osteoarthritis. However, little is known about preferences and barriers to the use of mobile apps by physical therapists or people aging with osteoarthritis. Therefore, we aimed to examine physical therapist and patient perspectives on mobile apps to support physical therapist-prescribed home exercise for people with osteoarthritis. Methods Eighteen physical therapists and 17 individuals with a history of physical therapy for osteoarthritis participated in the study. Focus groups (n = 6, three each with physical therapists and patients) were conducted to gather perspectives on three commercially available mobile apps designed for physical therapy exercise prescription. Semi-structured questions assessed feature preferences, ease of use, exercise completion support, clinical feasibility, and potential barriers and facilitators to using the apps. Recordings of the focus groups were transcribed verbatim. The study team iteratively coded transcripts using thematic analysis. Results Perspectives of patients and physical therapists intersected but differed on the mobile apps. All patients preferred video exercise prescription over traditional methods and both patients and therapists predicted challenges and opportunities with mobile communication. Four themes emerged: accountability, data-driven, communication boost, and duality of technology. Facilitators of home exercise through mobile apps included exercise tracking, feedback loop, personalization, and the potential for reduced in-person visits. Barriers included technological challenges, complex interface design, lack of universal applicability, and security concerns. Conclusion Mobile app technology has the potential to support exercise adherence for people with osteoarthritis. However, patients' and therapists' perspectives differ and highlight numerous challenges that limit the universal clinical adoption of this technology. While physical therapists acknowledged the potential to improve the rehabilitation experience with mobile apps, there was concern about reimbursement and time constraints in the current fee-for-service environment.

Electronic health record data extraction: Physical therapists' documentation of physical activity assessments and prescriptions for patients with chronic low back pain.

BACKGROUND: Despite physical activity being a major component of managing chronic low back pain, < 50% of patients receive physical activity interventions. Electronic Health Records can deepen our understanding about this clinical gap. OBJECTIVE: We aimed to: 1) develop and test a data abstraction form that captures physical activity documentation; and 2) explore physical therapists' documentation of physical activity assessments and interventions. METHODS: We developed a data abstraction form using previously published practice guidelines. After identifying the forms' inter-rater reliability, we used it to explore physical therapists' documentation related to physical activity assessments and interventions for patients with chronic low back pain. RESULTS: The final data abstraction form included information about physical activity history, assessments, interventions, general movement discussion, and plan. Our inter-rater reliability was high. Of the 18 patients, 66.7% had documentation about their PA history. Across the 56 encounters, 14 (25.0%) included an assessment, 18 (32.1%) an intervention, 18 (32.1%) a general movement discussion, and 12 (21.4%) included a plan. CONCLUSION: Using our reliable data abstraction form we identified a lack of documentation about physical activity assessments and interventions among patients with chronic low back pain. A larger study is needed to examine the generalizability of these results.

Physical function in older adults with and without a cancer history: Findings from the National Health and Aging Trends Study.

BACKGROUND: Previous studies identified physical function limitations in older cancer survivors, but few have included objective measures and most focused on breast and prostate cancer survivors. The current study compared patient-reported and objective physical function measures between older adults with and without a cancer history. METHODS: Our cross-sectional study used a nationally representative sample of community-dwelling, Medicare beneficiaries from the 2015 National Health and Aging Trends Study (n = 7495). Data collected included patient-reported physical function, including a composite physical capacity score and limitations in strength, mobility, and balance, and objectively measured physical performance metrics, including gait speed, five time sit-to-stand, tandem stand, and grip strength. All analyses were weighted to account for the complex sampling design. RESULTS: Thirteen percent of participants (n = 829) reported a history of cancer, of which more than half (51%) reported a diagnosis other than breast or prostate cancer. In models adjusted for demographics and health history, older cancer survivors had lower Short Physical Performance Battery scores (unstandardized beta [B] = -0.36; 95% CI: -0.64, -0.08), slower gait speed (B = -0.03; 95% CI: -0.05, -0.01), reduced grip strength (B = -0.86; 95% CI: -1.44, -0.27), worse patient-reported composite physical capacity (B = -0.43; 95% CI: -0.67, -0.18) and patient-reported upper extremity strength (B = 1.27; 95% CI: 1.07, 1.50) compared to older adults without cancer. Additionally, the burden of physical function limitations was greater in women than in men, which may be explained by cancer type. CONCLUSIONS: Our results extend studies in breast and prostate cancer to show worse objective and patient-reported physical function outcomes in older adults with a range of cancer types compared to those without a cancer history. Moreover, these burdens seem to disproportionately affect older adult women, underscoring the need for interventions to address functional limitations and prevent further health consequences of cancer and its treatment.

Physical activity for patients with chronic low back pain: What are physical therapists prescribing?

BACKGROUND: Despite the extensive evidence supporting physical activity (PA) for managing chronic low back pain (CLBP), little is known about PA prescription by physical therapists treating patients with CLBP. OBJECTIVE: 1) Explore how PA prescriptions provided by outpatient physical therapists treating patients with CLBP align with PA guidelines. 2) Examine the barriers and facilitators of PA prescription among physical therapists working with patients with CLBP. METHODS: We conducted a qualitative study with outpatient physical therapists who treat CLBP. Semi-structured interviews provided an understanding of physical therapist experience with PA prescription among patients with CLBP. The interviews were transcribed, coded, and analyzed thematically. RESULTS: The 18 participants had an average of 13.4 (6.4) years of clinical experience in outpatient physical therapy. Thematic analysis revealed: 1) Physical therapists' articulate knowledge of PA guidelines and importance of physical activity; 2) Patient factors take priority over the PA guidelines for people with CLBP; and 3) The importance of building and maintaining a strong patient-therapist relationship influences physical therapist prescription of PA for patients with CLBP. CONCLUSION: When providing PA recommendations for patients with CLBP, general movement recommendations are emphasized in place of explicit PA prescriptions. Our findings highlight factors for consideration when prescribing movement and PA for patients with CLBP.

Exercise Intensity Among Older Adults Participating From Home in Remotely Delivered EnhanceFitness.

We aimed to examine exercise intensity among older adults participating from home in remotely delivered EnhanceFitness (Tele-EF). Exercise intensity was assessed through Fitbit-measured heart rate and the Borg 10-point rating of perceived exertion over 1 week of a 16-week exercise program. Outcomes included mean minutes spent at or above the heart rate reserve calculated threshold for moderate intensity and mean rating of perceived exertion. Pearson and Spearman rank correlations were used to examine associations between baseline characteristics with exercise intensity. During the 60-min classes, the 55 participants achieved moderate intensity for a mean of 21.0 min (SD = 13.5) and had a mean rating of perceived exertion of 4.9 (SD = 1.2). There were no significant associations between baseline characteristics and exercise intensity. Older adults can achieve sustained moderate-intensity exercise during Tele-EF supervised classes. Baseline physical function, physical activity, and other health characteristics did not limit ability to exercise at a moderate intensity, though further investigation is warranted.

Prevalence and sociodemographic characteristics of US community-dwelling older adults with communication disabilities, using the national health and aging trends survey.

INTRODUCTION: Identifying the population-level prevalence of a disability group is a prerequisite to monitoring their inclusion in society. The prevalence and sociodemographic characteristics of older adults with communication disabilities (CDs) are not well established in the literature. In this study we sought to describe the prevalence and sociodemographic characteristics of community-dwelling older adults experiencing difficulties with understanding others or being understand when communicating in their usual language. METHODS: We conducted a cross-sectional analysis of the National Health and Aging Trends Survey (2015), a nationally representative survey of Medicare beneficiaries ages ≥ 65 years old (N = 7,029). We calculated survey weight-adjusted prevalence estimates by mutually exclusive subgroups of no, hearing only, expressive-only, cognitive only, multiple CDs, and an aggregate any-CD prevalence. We described race/ethnicity, age, gender, education, marital status, social network size, federal poverty status, and supplemental insurance for all groups. Pearson's chi-squared statistic was used to compare sociodemographic characteristics between the any-CD and no-CD groups. RESULTS: An estimated 25.3% (10.7 million) of community-dwelling older adults in the US experienced any-CDs in 2015; approximately 19.9% (8.4 million) experienced only one CD while 5.6% (2.4 million) had multiple. Older adults with CDs were more likely to be of Black race or Hispanic ethnicity as compared to older adults without CDs (Black 10.1 vs. 7.6%; Hispanic: 12.5 vs. 5.4%; P < 0.001). They also had lower educational attainment (Less than high school: 31.0 vs 12.4%; P < 0.001), lower poverty levels (<100% Federal poverty level: 23.5% vs. 11.1%; P < 0.001) and less social supports (Married: 51.3 vs. 61.0%; P < 0.001; Social network ≤ 1 person: 45.3 vs 36.0%; P < 0.001). CONCLUSIONS: The proportion of the older adult population experiencing any-CDs is large and disproportionately represented by underserved sociodemographic groups. These findings support greater inclusion of any-CDs into population-level efforts like national surveys, public health goals, health services, and community research aimed at understanding and addressing the access needs of older adults who have disabilities in communication.

Exploring the implementation potential of physical activity assessment and prescription tools in physical therapy practice: a mixed-method study.

BACKGROUND: Despite the benefits of physical activity (PA), especially related to aging, physical therapists do not perform regular PA prescriptions secondary to various barriers, including lack of tools. Therefore, we developed the Inventory of Physical Activity Barriers (IPAB). OBJECTIVE: Explore potential solutions that could address the current lack of PA prescription among United States-based physical therapists treating patients 50 years and older. METHOD: A convergent parallel mixed-method design consisting of focus groups and self-report questionnaires. Descriptive statistics were used for all quantitative variables. Focus groups were thematically coded. RESULTS: The 26 participants had 8.6 years (SD = 6.4) of clinical experience, 88.4% (n = 23) reported they regularly have PA conversations with patients, 65.4% (n = 17) regularly assess PA levels, and 19.2% (n = 5) regularly provide PA prescriptions. We identified three themes: 1) opportunities and challenges related to PA prescriptions; 2) lack of standardization in PA assessments and interventions; and 3) implementation potential for innovative solutions that address the current informal PA assessments and interventions. CONCLUSION: Physical therapists are amenable to incorporating innovative solutions that support physical activity prescription behavior. Therefore, we recommend the continued development and implementation of PA assessment and prescription tools.

Remotely delivered exercise to older rural cancer survivors: a randomized controlled pilot trial.

PURPOSE: The study aimed to determine the feasibility of remotely delivered exercise (tele-exercise) for older, rural cancer survivors and to explore the effects of tele-exercise on physical function, physical activity, and patient-reported outcomes. METHODS: Participants were rural cancer survivors age ≥ 60 years (79% female; mean age 70.4 ± 5.7) randomly assigned to the remotely delivered EnhanceFitness (tele-EF) exercise program, inclusive of aerobic, strength, and balance training and led by American Council on Exercise certified instructors for 1 h, 3 days/week for 16 weeks (n = 20) or to a waitlist control group (n = 19). We assessed feasibility, physical function, accelerometer-measured physical activity, and patient-reported outcomes at baseline and post intervention. RESULTS: Among those screened as eligible, 44 (64%) consented to participate with 39 randomized after completing baseline measures. Attrition was equivalent between groups (n = 1, each) with 95% completing the study. The median class attendance rate was 86.9% (interquartile range: 79-94%). Compared to controls, tele-EF participants had statistically significant improvement in the five-time sit-to-stand test (- 3.4 vs. - 1.1 s, p = 0.03, effect size = 0.44), mean daily light physical activity (+ 38.5 vs 0.5 min, p = 0.03, effect size = 0.72) and step counts (+ 1977 vs. 33, p = 0.01, effect size = 0.96). There were no changes in self-efficacy for exercise, fatigue, or sleep disturbance between groups. CONCLUSIONS: Findings indicate that tele-EF is feasible in older, rural cancer survivors and results in positive changes in physical function and physical activity. IMPLICATIONS FOR CANCER SURVIVORS: Tele-EF addresses common barriers to exercise for older, rural cancer survivors, including limited accessible opportunities for professional instruction and supervision.

The Relationship Between Mental and Physical Health and Walking During the COVID-19 Pandemic.

INTRODUCTION: COVID-19 policies such as quarantining, social isolation, and lockdowns are an essential public health measure to reduce the spread of disease but may lead to reduced physical activity. Little is known if these changes are associated with changes in physical or mental health. METHODS: Between September 2017 and December 2018 (baseline) and March 2020 and February 2021 (follow-up), we obtained self-reported demographic, health, and walking (only at follow-up) data on 2042 adults in primary care with multiple chronic health conditions. We examined whether the perceived amount of time engaged in walking was different compared with prepandemic levels and if this was associated with changes in Patient-Reported Outcomes Measurement Information System-29 mental and physical health summary scores. Multivariable linear regression controlling for demographic, health, and neighborhood information were used to assess this association. RESULTS: Of the 2042 participants, 9% reported more walking, 28% reported less, and 52% reported the same amount compared with prepandemic levels. Nearly 1/3 of participants reported less walking during the pandemic. Multivariable models revealed that walking less or not at all was associated with negative changes in mental (ß = -1.0; 95% CI [-1.6, -0.5]; ß = -2.2; 95% CI [-2.9, -1.4]) and physical (ß = -0.9; 95% CI [-1.5, -0.3]; ß = -3.1; 95% CI [-4.0, -2.3]) health, respectively. Increasing walking was significantly associated with a positive change in physical health (ß = 1.3; 95% CI [0.3, 2.2]). CONCLUSIONS: These findings demonstrate the importance of walking during the COVID-19 pandemic. Promotion of physical activity should be taken into consideration when mandating restrictions to slow the spread of disease. Primary care providers can assess patient's walking patterns and implement brief interventions to help patients improve their physical and mental health through walking.

A randomized trial to promote physical activity in adult pre-hypertensive and hypertensive patients.

The purpose of the pilot study was to determine the effectiveness of wearable activity trackers alone or in combination with behaviour change strategies for promoting physical activity (PA) among individuals with pre-hypertension or hypertension. A sample of 44 adults (68% female and mean age 55) were randomized to receive either a Fitbit Charge HR 3 alone (FB) or the Fitbit in combination with behaviour change strategies (i.e., goal setting, behaviour goal review, adaptive feedback) delivered by a trained health coach (FB+) for 12 weeks. Moderate and vigorous PA (MVPA), steps, and sedentary time (ST) were assessed using ActiGraph wGT3X-BT. The FB+ group significantly increased PA [+1854 (2518) steps/day, p < .01] and MVPA [+26 (34) mins/day, p < .05], and decreased their ST [-63 (73) mins/day, p < .01]. The FB group significantly increased  MVPA [+11 (16) mins/day, p < .05], and decreased their ST [-87 (117) mins/day, p < .01]. Participants in FB+ had a significantly greater increase in MVPA/day compared to FB only with a between-group effect size of 0.6 (p < .05). Using Fitbit for self-monitoring is effective in increasing PA and reducing ST among pre-hypertensive and hypertensive participants. Additional behaviour change support amplified the intervention effectiveness for promoting MVPA.

Evaluation of Electronic and Pen-and-Paper Formats of the Inventory of Physical Activity Barriers: A Randomized Crossover Study.

BACKGROUND: The Inventory of Physical Activity Barriers (IPAB) assesses physical activity participation barriers. Development, refinement, and psychometric evaluation of the IPAB occurred via an electronic format. However, various circumstances may require using a pen-and-paper format. As instrument formats are not always interchangeable, the authors aimed to establish whether 2 different formats (electronic and pen and paper) can be used interchangeably for the IPAB. METHODS: This randomized crossover study included 66 community-dwelling adults aged 50 years and older (mean age = 73 [SD = 7.6]). Half the sample completed the electronic format of the IPAB first and the pen-and-paper format second, and the other half completed them in reverse order. Tests of equivalence and a Bland-Altman plot were performed. RESULTS: The intraclass correlation coefficient between formats was .94, and kappa was .68. The mean difference between the 2 administration forms of the IPAB was 0.002 (P = .96). Both administration formats had high internal consistency (Cronbach alpha = .92 and .93) and illustrated construct validity (P ≤ .001 for both administration formats). CONCLUSION: Pen-and-paper and electronic formats of the IPAB are equivalent and, thus, can be used interchangeably among non-Hispanic whites who are highly educated. The format should be used consistently if completing preintervention and postintervention evaluations or comparing scores.

Remotely Delivered Exercise to Rural Older Adults With Knee Osteoarthritis: A Pilot Study.

OBJECTIVE: EnhanceFitness (EF) is an evidence-based exercise program recommended for management of osteoarthritis (OA). However, access to EF is limited in rural areas. Accordingly, we evaluated the feasibility and acceptability of remotely delivered EF (tele-EF) in rural, community-dwelling older adults with symptomatic knee OA. METHODS: A single-arm pilot trial of tele-EF classes was conducted. Videoconferencing was used to livestream the instructor-led, 1-hour EF classes 3 days/week for 12 weeks. Outcomes were assessed at baseline and immediately post intervention. RESULTS: A total of 15 of 27 potential participants (55%) were screen eligible and enrolled into the trial. Participants had a median age of 70 years (interquartile range: 67-75), and 14 (93%) were women. The median EF class attendance rate was 91% (interquartile range: 85%-94%). Knee pain, as measured by the Knee Injury and Osteoarthritis Outcome Score (KOOS), improved significantly from baseline to the 12-week end point (mean difference = -11.4 [95% confidence interval (CI): -20.9 to -2.0]; P = 0.02). In addition, participants' self-reported knee function improved significantly (mean difference in KOOS function score = -11.8 [95% CI: -18.4 to -5.2]; P < 0.01) as well as their physical capacity (mean difference in Timed Up and Go test time = 1.8 seconds [95% CI: 0.2-3.4]; P = 0.03). All participants (100%) were very satisfied with tele-EF classes, and 12 participants (86%) reported that their condition had much improved or very much improved since beginning the EF exercise program. Lastly, there were no serious adverse events. CONCLUSION: Findings from this pilot trial indicate that tele-EF is feasible and acceptable in rural older adults with knee OA.

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.

Nutrition Risk is Associated With Falls Risk in an Observational Study of Community-Dwelling, Rural, Older Adults.

OBJECTIVES: Poor nutritional status is a risk factor for falls and impedes recovery from falls in older adults. The primary objective of this study was to investigate the relationship between nutrition status and fall risk over time in a cohort of older adults. METHODS: Using an observational analytic study design, we collected demographic, fall risk, nutrition risk, food insecurity, and incident falls data from community-dwelling older Vermonters. RESULTS: Data from 708 participants (70.3 years ± 6.6; 82% female) indicate a significant association between fall risk and nutrition risk (p < 0.001), fall risk and food insecurity (p < 0.001), and food insecurity and nutrition risk (p < 0.001). After adjusting for potential confounders, elevated nutrition risk was significantly associated with an incident fall over the next 6 months (p < 0.05). CONCLUSION: Given the evidence for an association between nutrition status and falls, additional research, in a more diverse population, is needed to understand the nuances of these relationships.

Community-Dwelling Older Adults and Physical Activity Recommendations: Patterns of Aerobic, Strengthening, and Balance Activities.

Though it is known that most older adults do not meet the recommended physical activity (PA) guidelines, little is known regarding their participation in balance activities or the full guidelines. Therefore, we sought to describe PA patterns among 1,352 community-dwelling older adult participants of the Adult Changes in Thought study, a longitudinal cohort study exploring dementia-related risk factors. We used a modified version of the Community Healthy Activities Model Program for Seniors questionnaire to explore PA performed and classify participants as meeting or not meeting the full guidelines or any component of the guidelines. Logistic regression was used to identify factors associated with meeting PA guidelines. Despite performing 10 hr of weekly PA, only 11% of participants met the full guidelines. Older age, greater body mass index, needing assistance with instrumental daily activities, and heart disease were associated with decreased odds of meeting PA guidelines. These results can guide interventions that address PA among older adults.

The Inventory of Physical Activity Barriers for Community-Dwelling Adults 50 Years of Age and Older: Development and Preliminary Validation.

BACKGROUND: Health care providers, including physical therapists, need to identify the reasons for insufficient physical activity (PA) to assist the 56% to 73% of community-dwelling adults 50 years of age and older who are not performing the recommended 150 minutes of moderate to vigorous PA. Currently, there is no feasible, multifactorial tool to assess PA barriers among this population. Without a tool, health care providers must either rely on self-generated questions or collate results from multiple assessments to identify PA barriers related to personal, social, and environmental factors, which can be time-consuming and incomplete. PURPOSE: To develop the Inventory of Physical Activity Barriers (IPAB), an assessment tool that examines personal, social, and environmental PA barriers. METHODS: We developed and psychometrically evaluated the IPAB using a 3-phase process. For phase 1, we used a deductive method to develop the initial scale. During phase 2, we refined the scale and explored its psychometric properties by collecting cross-sectional pilot data on community-dwelling adults 50 years of age and older. We used descriptive statistics, item-scale correlations, construct validity via Mann-Whitney U test, and internal consistency via Cronbach α to analyze the data from phase 2. After identifying the scale's potential for being valid and reliable, we implemented phase 3, a modified Delphi technique. RESULTS: Using item-scale correlations, descriptive statistics, and consensus among PA experts, we refined the initial scale from 172 items to 40 items. The 40-item IPAB demonstrated good construct validity (determined by the scale's ability to differentiate between individuals who did and did not meet 150 min/wk of moderate to vigorous PA; P = .01) and internal consistency (Cronbach α of 0.97). CONCLUSION: Our preliminary results suggest that the IPAB is valid and reliable. Using the IPAB, health care providers will be able to identify patients' PA barriers and thus develop individualized PA prescriptions, an evidence-based method of increasing PA.

The Inventory of Physical Activity Barriers for Adults 50 Years and Older: Refinement and Validation.

BACKGROUND AND OBJECTIVES: Due to health consequences associated with insufficient physical activity (PA), particularly among aging adults, health care providers should assess and address lack of PA participation. Addressing lack of PA means developing individualized PA prescriptions that incorporate solutions to PA participation barriers. Assessing PA participation barriers can be done through the Social Ecological Model-based Inventory of Physical Activity Barriers Scale (IPAB). This study aimed to refine the initial 40-item IPAB and determine its reliability and validity. RESEARCH DESIGN AND METHODS: Five hundred and three community-dwelling adults 50 years and older completed a demographic and health questionnaire, the Physical Activity Vital Sign, the IPAB, and a feedback questionnaire. For scale refinement, half of the data were used for exploratory factor analysis and the other half for confirmatory factor analysis. The refined scale underwent reliability and validity assessment, including internal consistency, test-retest reliability, and construct validity. RESULTS: The refined scale contains 27 items consisting of 7 factors and 1 stand-alone item: (a) environmental, (b) physical health, (c) PA-related motivation, (d) emotional health, (e) time, (f) skills, (g) social, and (h) energy (a stand-alone item). The 27-item IPAB has good internal consistency (alpha = 0.91) and high test-retest reliability (intraclass correlation coefficient = 0.99). The IPAB's mean scores were statistically different between those who met the recommended levels of PA and those who did not (p < .001). DISCUSSION AND IMPLICATIONS: The information gathered through the IPAB can guide discussions related to PA participation barriers and develop individualized PA prescriptions that incorporate solutions to the identified barriers.

Technology Support Challenges and Recommendations for Adapting an Evidence-Based Exercise Program for Remote Delivery to Older Adults: Exploratory Mixed Methods Study.

BACKGROUND: Tele-exercise has emerged as a means for older adults to participate in group exercise during the COVID-19 pandemic. However, little is known about the technology support needs of older adults for accessing tele-exercise. OBJECTIVE: This study aims to examine the needs of older adults for transition to tele-exercise, identify barriers to and facilitators of tele-exercise uptake and continued participation, and describe technology support challenges and successes encountered by older adults starting tele-exercise. METHODS: We used an exploratory, sequential mixed methods study design. Participants were older adults with symptomatic knee osteoarthritis (N=44) who started participating in a remotely delivered program called Enhance Fitness. Before the start of the classes, a subsample of the participants (n=10) completed semistructured phone interviews about their technology support needs and the barriers to and facilitators for technology adoption. All of the participants completed the surveys including the Senior Technology Acceptance Model scale and a technology needs assessment. The study team recorded the technology challenges encountered and the attendance rates for 48 sessions delivered over 16 weeks. RESULTS: Four themes emerged from the interviews: participants desire features in a tele-exercise program that foster accountability, direct access to helpful people who can troubleshoot and provide guidance with technology is important, opportunities to participate in high-value activities motivate willingness to persevere through the technology concerns, and belief in the ability to learn new things supersedes technology-related frustration. Among the participants in the tele-exercise classes (mean age 74, SD 6.3 years; 38/44, 86% female; mean 2.5, SD 0.9 chronic conditions), 71% (31/44) had a computer with a webcam, but 41% (18/44) had little or no experience with videoconferencing. The initial technology orientation sessions lasted on average 19.3 (SD 10.3) minutes, and 24% (11/44) required a follow-up assistance call. During the first 2 weeks of tele-exercise, 47% of participants (21/44) required technical assistance, which decreased to 12% (5/44) during weeks 3 to 16. The median attendance was 100% for the first 6 sessions and 93% for the subsequent 42 sessions. CONCLUSIONS: With appropriate support, older adults can successfully participate in tele-exercise. Recommendations include individualized technology orientation sessions, experiential learning, and availability of standby technical assistance, particularly during the first 2 weeks of classes. Continued development of best practices in this area may allow previously hard-to-reach populations of older adults to participate in health-enhancing, evidence-based exercise programs.

Comprehensive comparison of Apple Watch and Fitbit monitors in a free-living setting.

OBJECTIVES: The aim of this study was to evaluate the accuracy of three consumer-based activity monitors, Fitbit Charge 2, Fitbit Alta, and the Apple Watch 2, all worn on the wrist, in estimating step counts, moderate-to-vigorous minutes (MVPA), and heart rate in a free-living setting. METHODS: Forty-eight participants (31 females, 17 males; ages 18-59) were asked to wear the three consumer-based monitors mentioned above on the wrist, concurrently with a Yamax pedometer as the criterion for step count, an ActiGraph GT3X+ (ActiGraph) for MVPA, and a Polar H7 chest strap for heart rate. Participants wore the monitors for a 24-hour free-living condition without changing their usual active routine. MVPA was calculated in bouts of ≥10 minutes. Pearson correlation, mean absolute percent error (MAPE), and equivalence testing were used to evaluate the measurement agreement. RESULTS: The average step counts recorded for each device were as follows: 11,734 (Charge2), 11,922 (Alta), 11,550 (Apple2), and 10,906 (Yamax). The correlations in steps for the above monitors ranged from 0.84 to 0.95 and MAPE ranged from 17.1% to 35.5%. For MVPA minutes, the average were 76.3 (Charge2), 63.3 (Alta), 49.5 (Apple2), and 47.8 (ActiGraph) minutes accumulated in bouts of 10 or greater minutes. The correlation from MVPA estimation for above monitors were 0.77, 0.91, and 0.66. MAPE from MVPA estimation ranged from 44.7% to 55.4% compared to ActiGraph. For heart rate, correlation for Charge2 and Apple2 was higher for sedentary behavior and lower for MVPA. The MAPE ranged from 4% to 16%. CONCLUSION: All three consumer monitors estimated step counts fairly accurately, and both the Charge2 and Apple2 reported reasonable heart rate estimation. However, all monitors substantially underestimated MVPA in free-living settings.

Utilization of wearable technology to assess gait and mobility post-stroke: a systematic review.

BACKGROUND: Extremity weakness, fatigue, and postural instability often contribute to mobility deficits in persons after stroke. Wearable technologies are increasingly being utilized to track many health-related parameters across different patient populations. The purpose of this systematic review was to identify how wearable technologies have been used over the past decade to assess gait and mobility in persons with stroke. METHODS: We performed a systematic search of Ovid MEDLINE, CINAHL, and Cochrane databases using select keywords. We identified a total of 354 articles, and 13 met inclusion/exclusion criteria. Included studies were quality assessed and data extracted included participant demographics, type of wearable technology utilized, gait parameters assessed, and reliability and validity metrics. RESULTS: The majority of studies were performed in either hospital-based or inpatient settings. Accelerometers, activity monitors, and pressure sensors were the most commonly used wearable technologies to assess gait and mobility post-stroke. Among these devices, spatiotemporal parameters of gait that were most widely assessed were gait speed and cadence, and the most common mobility measures included step count and duration of activity. Only 4 studies reported on wearable technology validity and reliability metrics, with mixed results. CONCLUSION: The use of various wearable technologies has enabled researchers and clinicians to monitor patients' activity in a multitude of settings post-stroke. Using data from wearables may provide clinicians with insights into their patients' lived-experiences and enrich their evaluations and plans of care. However, more studies are needed to examine the impact of stroke on community mobility and to improve the accuracy of these devices for gait and mobility assessments amongst persons with altered gait post-stroke.
