Mapping the extent of the literature and psychometric properties for the Physical Activity Scale for the Elderly (PASE) in community-dwelling older adults: a scoping review.

BACKGROUND: Identifying valid and accessible tools for monitoring and improving physical activity levels is essential for promoting functional ability and healthy aging. The Physical Activity Scale for the Elderly (PASE) is a commonly used and recommended self-report measure of physical activity in older adults. The objective of this scoping review was to map the nature and extent to which the PASE has been used in the literature on community-dwelling older adults, including the evidence for its psychometric properties. METHODS: Seven electronic databases (MEDLINE (Ovid), Embase (Ovid), AMED (Ovid), Emcare (Ovid), CINAHL (EBSCO), Ageline (EBSCO)) were searched from inception to January 25, 2023. Studies were included if physical activity was part of the aim(s) and measured using the PASE, participants had a mean age of 60 years or older and lived in the community, and papers were peer-reviewed journal articles published in English. Pairs of independent reviewers screened abstracts, full-texts, and extracted data. Where possible, weighted mean PASE scores were calculated for different subgroups based on age, sex, and clinical population. RESULTS: From 4,124 studies screened, 232 articles from 35 countries met the inclusion criteria. Most studies were cross-sectional (60.78%), completed in high-income countries (86.4%) and in North America (49.57%). A variety of clinical conditions were included (n = 21), with the most common populations being osteoarthritis (n = 13), Parkinson's disease (n = 11), and cognitive impairment (n = 7). Psychometric properties of ten versions of the PASE were found. All versions demonstrated acceptable test-retest reliability. Evidence for construct validity showed moderate correlations with self-reported physical activity, fair to moderate with accelerometry derived activity and fair relationships with physical function and self-reported health. Pooled means were reported in graphs and forest plots for males, females, age groups, and several clinical populations. CONCLUSION: The PASE was widely used in a variety of clinical populations and geographical locations. The PASE has been culturally adapted to several populations and evaluated for its reliability and convergent validity; however, further research is required to examine responsiveness and predictive validity. Researchers can use the weighted mean PASE scores presented in this study to help interpret PASE scores in similar populations. OSF REGISTRATION: osf.io/7bvhx.

Bridging the divide: supporting and mentoring trainees to conceptualize, plan, and integrate engagement of people with lived experience in health research.

Health researchers are encouraged by governments, funders, and journals to conduct research in partnership with people with lived experience. However, conducting research with authentic engagement and partnership with those who are experts by experience, but may not have research methods training, requires resources and specialized skills. The McMaster Collaborative for Health and Aging developed a fellowship program for trainees that builds their capacity to conduct research in partnership with older adults with relevant lived experience. We share this case example, with its successes and challenges, to encourage creative reformation of traditional research training.The Collaborative used an iterative design process, involving researchers, trainees and older adult and caregiver partners, who, together, developed a fellowship program for trainees that provides support and mentorship to plan and conduct health research in partnership with people with lived experience.Since 2022, the Partnership in Research Fellowship has been offered biannually. The application process was purposefully designed to be both constructive and supportive. Opportunities for one-on-one consultations; key resources, including a guide for developing a plan to involve people with relevant lived experience; and feedback from older adult and researcher reviewers are provided to all applicants. Successful trainees engage with older adult and caregiver partners from the Collaborative to advance and enhance a range of skills from facilitating partner meetings to forming advisory committees. Trainees are awarded $1500 CAD to foster reciprocal partnerships. Ten graduate students from various disciplines have participated. Trainees reported positive impacts on their knowledge, comfort, and approach to partnered research. However, the time required for undertaking partnered research activities and involving diverse partners remain obstacles to meaningful engagement.Partnering with people with lived experience in the design of educational programs embeds the principles of partnership and can increase the value and reward for all involved. We share the Partnership in Research Fellowship as a case example to inspire new and transformative approaches in research training and mentorship that will move the field forward from engagement theory to meaningful enactment.

Health researchers are encouraged by governments, funders, and journals to conduct research in partnership with individuals with relevant health conditions or experience. However, conducting research with individuals who are experts by experience, but may not have research training, requires resources and specialized skills. The McMaster Collaborative for Health and Aging developed a fellowship program to support and mentor trainees to conduct their research in partnership with people with lived experience and turn engagement theory into action.The Collaborative involved researchers, trainees, and older adults in the development of the fellowship program. Since 2022, the Partnership in Research Fellowship has been offered twice a year. The application process was designed to be both supportive and informative. Opportunities for one-on-one consultations; key resources, including guiding questions to consider when planning to involve people with relevant lived experience; and feedback from older adults and researchers, are provided to all applicants. Each trainee receives $1500 CAD to support building strong, two-way partnerships. Since the fellowship's launch, 10 graduate students from different fields have participated. Trainees reported improvements in their knowledge and comfort to partner with people with lived experience in research. However, challenges, such as the extra time needed for conducting partnered research as well as locating and involving those from diverse backgrounds, were identified.Involving people with lived experience in the design of research training incorporates partnership principles and may enhance the benefits and satisfaction for everyone involved. We share the Partnership in Research Fellowship, as an example, to inspire new approaches in research training and mentorship.

Acceptability, Reliability, and Validity of Virtually Administered Gait Speed Tests.

OBJECTIVES: To evaluate the acceptability, reliability (inter- and intrarater), and validity (convergent, known groups, and predictive) of virtually administered gait speed tests for community-dwelling older adults. DESIGN: A prospective cohort study was performed, tracking health outcomes for a year. SETTING AND PARTICIPANTS: The 3-m gait speed test at usual and fast pace was administered to community-dwelling older adults over Zoom. METHOD: To examine acceptability, participants completed questionnaires regarding telehealth usability and experience. Virtual gait speed tests were administered at baseline and 24 to 72 hours later to evaluate reliability. Self-report mobility measures were used to examine convergent and known-groups validity. Participants' health outcomes were tracked for a year to evaluate predictive validity. RESULTS: Sixty participants completed the baseline assessment and 52 completed the second assessment. Participants reported an overall positive experience with the test. Intraclass correlation coefficients for reliability ranged from 0.79 to 0.90. For convergent validity, correlations >0.30 were found predominantly for usual gait speed with self-report mobility measures. Both the usual- and fast-gait speed were able to discriminate between difficulty walking and gait aid use. Usual gait speed was able to predict specialist and family doctor visits and fast gait speed was able to predict rehabilitation specialist visits over 1 year. CONCLUSIONS AND IMPLICATIONS: Our findings demonstrate support for the acceptability, reliability, and validity of virtually administered gait speed tests for community-dwelling older adults. Although future studies are needed to examine the validity of virtual gait speed tests in larger and more diverse samples to improve generalizability of results, clinicians and researchers can virtually administer 3-m gait speed tests with confidence that scores are trustworthy and reflect older adults' mobility.

The effects of co-designed physical activity interventions in older adults: A systematic review and meta-analysis.

BACKGROUND: Physical activity (PA) declines with age despite the knowledge that physical inactivity is a leading cause of disease, death, and disability worldwide. To better tailor PA interventions to older adults, researchers are turning to the collaborative principles of co-design. The purpose of this systematic review was to compare the effectiveness of co-designed PA interventions and standard care for increasing PA and other health outcomes (i.e., physical function, quality of life, mental health, functional independence, attendance and attrition rates) in older adults. METHODS: A search was conducted in MEDLINE, AgeLine, CINAHL, Embase, and SPORTDiscus. Records were screened by independent pairs of reviewers. Primary research studies conducted among community-dwelling older adults (age 60+) comparing co-designed PA interventions to standard care were considered for inclusion. Controls included wait-list control, usual care, sham interventions, PA interventions without the use of co-design, and no intervention. A random effects meta-analysis was conducted, and the standardized mean difference (SMD) was used to report effect estimates. Quality of evidence was rated using GRADE. RESULTS: Of 16,191 studies screened, eight (N = 16,733) were included in this review. Most studies reported results favouring the effect of co-design on physical activity; however, only two studies (N = 433) could be pooled for meta-analysis resulting in a SMD of 0.28, (95% CI = -0.13 to 0.69; p = 0.19; I2 = 56%) immediately post-intervention. The GRADE quality of evidence was very low. The quantitative analysis of three studies reported improved physical function. CONCLUSION: This review did not demonstrate that co-designed PA interventions are more effective than standard care for increasing PA in older adults; however, evidence was limited and of very low quality. Further well-designed trials are warranted to better understand the impacts of co-designed PA interventions and how to best implement them into practice.

Mapping sex and gender differences in falls among older adults: A scoping review.

BACKGROUND: There is growing recognition of the importance of sex and gender differences within falls literature, but the characterization of such literature is uncertain. The aim of this scoping review was to (1) map the nature and extent of falls literature examining sex or gender differences among older adults, and (2) identify gaps and opportunities for further research and practice. METHODS: We used a scoping review methodology. Eligible studies included participants with a mean age of ≥ 60 years and study aims specifying falls and either sex or gender concepts. MEDLINE, Embase, CINAHL, Ageline, and Psychinfo databases were searched from inception to March 2, 2022. Records were screened and charted by six independent reviewers. Descriptive and narrative reports were generated. RESULTS: A total of 15,266 records were screened and 74 studies were included. Most studies reported on sex and gender differences in fall risk factors (n = 52, 70%), incidence/prevalence (n = 26, 35%), fall consequences (n = 22, 30%), and fall characteristics (n = 15, 20%). The majority of studies (n = 70, 95%) found significant sex or gender differences in relation to falls, with 39 (53%) identifying significant sex differences and 31 (42%) identifying significant gender differences. However, only three (4%) studies defined sex or gender concepts and only nine (12%) studies used sex or gender terms appropriately. Fifty-six (76%) studies had more female participants than males. Four (5%) were intervention studies. Studies did not report falls in line with guidelines nor use common fall definitions. CONCLUSION: Sex and gender differences are commonly reported in falls literature. It is critical for future research to use sex and gender terms appropriately and include similar sample sizes across all genders and sexes. In addition, there is a need to examine more gender-diverse populations and to develop interventions to prevent falls that address sex and gender differences among older adults.

Determinants of physical activity in community-dwelling older adults: an umbrella review.

INTRODUCTION: Physical activity (PA) is critical for disease prevention and maintaining functional ability with aging. Despite this, as many as 50% of older adults in populations worldwide are considered insufficiently active. There is a recognized need to mobilize policies targeted toward modifiable determinants of healthy aging like PA. This umbrella review aimed to summarize the evidence for determinants of PA in community-dwelling older adults. METHODS: A research librarian searched six databases. Systematic and scoping reviews were included if they investigated community-dwelling people with a mean age of 60 + years and examined a relationship between a determinant and any type of PA. Two independent reviewers screened and extracted data from all reviews. JBI methodology and Critical Appraisal Checklist for Systematic Reviews and Research Syntheses were followed and information on the quality of the evidence was extracted. RESULTS: From 17,277 records screened,11 reviews representing > 300 unique primary papers were ultimately included. Only 6% of studies included in all reviews had longitudinal designs. Included studies used a large variety of PA measures, with 76% using only self-report, 15% using only direct measures (e.g., accelerometry), 3% using both types, and 6% with no outcome measure reported. Only four reviews provided a definition of PA and there was substantial inconsistency in the way PA was categorised. Community level influences, which only included the physical environment, were the most commonly assessed (6/11) with more than 70% of the summarized relationships demonstrating null associations. Three out of four reviews reported a positive relationship between walkability and PA in general community-dwelling older adults. There was also evidence supporting relationships between presence of social support for PA, younger age, and men having higher PA from a single systematic review. None of the included reviews assessed the quality of evidence but over 60% performed a risk of bias assessment. CONCLUSIONS: Walkability, age, gender, and social support for PA were the most supported PA determinants identified. Further research should focus on interpersonal and intrapersonal influences and incorporate direct measures of PA with clear operational definitions. There is a need for longitudinal study designs to further understand determinants of PA behaviour trajectories.

Measuring physical performance in later life: reliability of protocol variations for common performance-based mobility tests.

BACKGROUND AND AIMS: Performance-based tests of mobility or physical function such as the Timed Up and Go (TUG), gait speed, chair-rise, and single-leg stance (SLS) are often administered using different protocols in aging populations, however, the reliability of their assessment protocols is not often considered. The purpose of this study was to examine the reliabilities of frequently used assessment protocols for the TUG, gait speed, chair-rise, and SLS in different age groups. METHODS: We administered the following assessment protocols in an age-stratified (50-64, 65-74, 75+ years) sample of participants (N = 147) from the Canadian Longitudinal Study on Aging (CLSA): TUG fast pace and TUG normal pace: TUG-cognitive counting backwards by ones and counting back by threes, gait speed with 3-m and 4-m course, chair-rise with arms crossed and allowing the use of arms, and SLS using preferred leg or both legs-on two occasions within 1 week. We assessed the relative (intra-class correlation) and absolute reliability (standard error of measurement, SEM and minimal detectable change, MDC) for each protocol variation and provided recommendations based on relative reliability. RESULTS: For participants aged 50-64 years, our results suggest better reliability for TUG fast-pace compared with normal-pace (ICC and 95% CI 0.70; 0.41-0.85 versus 0.38; 0.12-0.59). The reliability values for 3-m gait speed were potentially higher than for 4-m gait speed (ICC 0.75; 0.67-0.82 versus 0.64; 0.54-0.73) and values for chair-rise suggested better reliability allowing participants to use their arms than with arms crossed (ICC 0.79; 0.66-0.86 versus 0.64; 0.45-0.77) for participants overall. For participants aged 75+ years, ICCs for SLS with the preferred leg showed better reliability than for both legs (ICC = 0.62-0.79 versus 0.30-0.39). CONCLUSIONS AND DISCUSSION: These reliability data and the recommendations can help guide the selection of the most appropriate performance-based test protocols for measuring mobility in middle-aged and older community-dwelling adults.

Undertaking Rehabilitation Research During the COVID-19 Pandemic: Emergent Strategies From a Trainee-Faculty Workshop.

Background: The COVID-19 pandemic has disrupted everyday rehabilitation research. Many academic institutions have halted in-person human research including rehabilitation sciences. Researchers are faced with several barriers to continuing their research programs. The purpose of this perspective article is to report the results of an interdisciplinary workshop aimed at understanding the challenges and corresponding strategies for conducting rehabilitation research during the COVID-19 pandemic. Methods: Twenty-five rehabilitation researchers (17 trainees and eight faculty) attended a 2-h facilitated online workshop in to discuss challenges and strategies they had experienced and employed to conduct rehabilitation research during the COVID-19 pandemic. Results: Rehabilitation researchers reported challenges with (1) pandemic protocol adjustments, (2) participant accessibility, and (3) knowledge dissemination, along with corresponding strategies to these challenges. Researchers experienced disruptions in study outcomes and intervention protocols to adhere to public health guidelines and have suggested implementing novel virtual approaches and study toolkits to facilitate offsite assessment. Participant accessibility could be improved by engaging community stakeholders in protocol revisions to ensure equity, safety, and feasibility. Researchers also experienced barriers to virtual conferences and publication, suggested opportunities for smaller networking events, and revisiting timeframes for knowledge dissemination. Conclusion: This perspective article served as a catalyst for discussion among rehabilitation researchers to identify novel and creative approaches that address the complexities of conducting rehabilitation research during the COVID-19 pandemic and beyond.

Interventions Including Smart Technology Compared With Face-to-face Physical Activity Interventions in Older Adults: Systematic Review and Meta-analysis.

BACKGROUND: This is a systematic review of randomized controlled trials and a meta-analysis comparing smart technology with face-to-face physical activity (PA) interventions in community-dwelling older adults (mean age 60 years). OBJECTIVE: This study aims to determine the effect of interventions including smart technology components compared with face-to-face PA interventions on PA and physical function in older adults. The secondary outcomes are depression, anxiety, and health-related quality of life. METHODS: We searched MEDLINE, Embase, CINAHL, and AMED electronic databases from inception to February 2021. Two independent reviewers screened titles, abstracts, and full texts and performed data extraction and risk of bias assessments using the Cochrane risk of bias tool. The Grading of Recommendations Assessment, Development and Evaluation was used to evaluate the quality of the evidence. We provided a narrative synthesis on all included studies and, where possible, performed meta-analyses for similar outcomes. RESULTS: This review included 19 studies with a total of 3455 participants. Random effects meta-analyses showed that interventions with smart technology components resulted in improved step count (mean difference 1440 steps, 95% CI 500-2390) and total PA (standardized mean difference 0.17, 95% CI 0.02-0.32) compared with face-to-face alone. There was no difference between groups in terms of the measures of physical function. Smart technology alone did not show significant differences between groups in any outcome. The quality of the evidence was very low based on the Grading of Recommendations Assessment, Development and Evaluation criteria. CONCLUSIONS: Interventions that include smart technology may improve daily step counts by an average of 1440 steps in community-dwelling older adults; however, the quality of the evidence was very low. Future studies are needed to improve the certainty of these results. TRIAL REGISTRATION: PROSPERO CRD42020135232; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=135232.

The use of co-design in developing physical activity interventions for older adults: a scoping review.

BACKGROUND: Promoting physical activity (PA) participation in older adults is important for preserving quality of life and functional independence. Co-design has been shown to increase engagement of end-users in health-related policies and interventions. This scoping review aimed to examine how co-design has been used to develop PA interventions for older adults. METHODS: We searched MEDLINE, EMBASE, AMED, and CINAHL. Peer-reviewed primary research studies that met the following criteria were included: had at least one participant aged ≥60 years involved in the co-design process and the intervention was delivered to individuals whose mean age was ≥60, used co-design methodologies, and any form of PA. After duplicate removal, two or more independent reviewers completed title and abstract and full text screening. Data were extracted from the included studies according to study aims. RESULTS: Of the 29 included studies, 12 different terms were used to describe co-design with variable operational definitions that we consolidated into five proposed components. Fifteen studies engaged users in a consultative way, 13 studies using collaboration, and one study engaged end-users in consumer-control. No studies involved end-users in the dissemination phase. Further, no studies directly measured the effectiveness of the co-design process. Five categories of barriers and facilitators to co-design were identified including frameworks and methodologies, logistics, relationships, participation, and generalizability. CONCLUSIONS: There is a large degree of variability in how co-design is used to develop PA interventions for older adults. Our findings can be used by researchers to improve rigor and standardization in this emerging field. TRIAL REGISTRATION: osf.io/vsw2m.
