Therefore, the purpose of this study was to examine the mediating role of physical function in the relationship between self-reported pain intensity and interference and cognitive function in middle-to-older aged adults with knee pain.Methods: Middle-to-older aged participants with knee pain (n = 202) completed the Graded Chronic Pain Scale to assess pain intensity and interference, the Short Performance Physical Battery to assess lower-extremity physical function, and the Montreal Cognitive Assessment to assess global cognitive function. Linear regression-based mediation analyses were used to assess associations between pain intensity and interference and cognitive function, with lower-extremity physical function as the mediator.Results: The direct relationship between pain intensity and cognitive function was significant (β = -0.269, p < .001) and remained significant when physical function was included as a mediator (c'=-0.0854, p = .003). The direct relationship between pain interference and cognitive function was also significant (β = -0.149, p = .023) but was attenuated when physical function was included as a mediator (c'=-0.0100, p = .09).Conclusion: Physical function partially mediated the relationship between pain intensity and cognitive function and fully mediated the relationship between pain interference and cognitive function. Significance/Implications: Higher levels of pain intensity and interference may lead to worse cognitive function when physical function is also impaired. Improving physical function may improve cognitive function in those with pain.","PeriodicalId":51073,"journal":{"name":"Journal of Aging and Physical Activity","volume":" ","pages":"1-7"},"PeriodicalIF":1.4,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143400690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were evaluated using the Community Integration Questionnaire, Western Ontario and McMaster Universities Osteoarthritis Index, International Physical Activity Questionnaire, Pain Quality Assessment Scale, and World Health Organization Quality of Life-old module Scales.Results: The mean age of 92 older adults included in the study was 67.5 ± 7.6 years. Specifically, for every 0.599 unit decrease in the Western Ontario and McMaster Universities Osteoarthritis Index physical function score (indicating an improvement in physical function), the community integration level increased by 0.196 units. Additionally, for every 0.380 unit increase in total physical activity level (measured in metabolic equivalent of task), the community integration level increased by 0.001 units. Also, community integration was negatively associated with pain intensity and positively associated with quality of life (p < .05).Conclusion: In the treatment of knee osteoarthritis, it is essential to provide intervention support to combat the symptoms of the disease, increase physical activity, and maintain community integration.Implications: In older adults diagnosed with knee osteoarthritis, community integration decreases as the severity of osteoarthritis increases with age. For older adults with knee osteoarthritis to have a better quality of life and active aging, it would be appropriate to add interventions to maintain and increase community integration in osteoarthritis treatment programs.","PeriodicalId":51073,"journal":{"name":"Journal of Aging and Physical Activity","volume":" ","pages":"1-7"},"PeriodicalIF":1.4,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143392374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding what motivates peer volunteers is valuable for the feasibility of volunteering schemes. This scoping review aims to explore the motivations of peer volunteers aged over 50 who participate in programs that promote physical activity. Four databases were searched in March 2023 with no date restrictions. The inclusion criteria were adults over 50 years of age, experience in physical activity peer-volunteering schemes, assessed volunteer motivation, and uses English language. Nine studies were included (252 participants, aged 54-85) Peer-volunteer and volunteering characteristics were extracted from the papers. An inductive thematic analysis approach was taken to analyze the motivation data. The themes were then mapped onto theoretical constructs of motivation. Three themes of motivation emerged that could enable us to better design peer-volunteer recruitment strategies: altruistic (giving back), personal improvement (meeting goals), and past experience (helping others overcome experienced barriers). The review suggested that peer-volunteer motivations fall in line with the mechanisms of motivation suggested by psychological theories such as social cognitive and self-determination theories. To improve peer-volunteer uptake and retention, appropriate theoretical frameworks should be employed to inform the content of future interventions to ensure that volunteers will have their motivations met.","PeriodicalId":51073,"journal":{"name":"Journal of Aging and Physical Activity","volume":" ","pages":"1-11"},"PeriodicalIF":1.4,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mixed methods were employed to assess rating-based responses and examine themes derived from open-ended responses.Results: Twenty-three participants completed the surveys (mean age: 73 years, Short Physical Performance Battery: 8.5, 96% male). Overall, participants were satisfied with the PT treatment (80%), and over 85% responded that the PT treatment met its objectives by improving their mobility. Veterans rated functional power training as challenging and the most valuable component of Live Long Walk Strong mobility training. Factors that influenced Veterans' motivations for meeting their exercise goals, were having a personal goal, a motivated physical therapist, and scheduled appointments. Participants rated aspects of behavioral coaching to be \"somewhat useful\" or \"very useful.\" Approximately half of the Veterans did not use the exercise journal to keep track of their home exercises. Reasons for not using the exercise journal were feeling busy or already having an exercise routine.Conclusion: Our results highlight the importance of prescribing challenging and meaningful PT treatment even among mobility-limited Veterans. Veterans may achieve their exercise goals by being instructed by a motivated physical therapist, having personal goals, and scheduling future appointments. There may be individual variability among those who may benefit from aspects of behavioral coaching and may need to be adjusted based on Veteran's needs.","PeriodicalId":51073,"journal":{"name":"Journal of Aging and Physical Activity","volume":" ","pages":"1-8"},"PeriodicalIF":1.4,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143015749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this cross-sectional study, we aimed to test the correlation between the 30-s sit-to-stand power test (30STSp) outcome and body balance in older adults. We evaluated physically active male and female (n = 51) individuals with an age range of 60-80 years (M = 69.29). Participants were assessed on the maximum number of repetitions for 30STSp and on the performance of balance tasks, as follows: quiet standing in unipedal support, unipedal support while alternately touching two targets on the ground with the toe of the nonsupporting foot in either the anteroposterior (AP) or mediolateral (ML) direction, and paced sit-to-stand supported on a narrow bipedal support base. Performance on the balance tasks was measured through smartphone-based triaxial trunk accelerometry (meters per second squared), with analysis made through root mean square for the AP and ML axes. Analysis indicated significant negative correlation coefficients of 30STSp outcome with trunk acceleration on unipedal quiet stance tasks both in the ML (rs = -.46) and AP (rs = -.40) directions and with the AP alternate target touching task for ML trunk acceleration (rs = -.34) and the ML alternate target touching task for AP trunk acceleration (rs = -.31). These results suggest that in active older adults, the 30STSp outcome is associated with balance in unipedal quiet standing and dynamic tasks. Our findings indicate the contribution of balance control in the performance of 30STSp.","PeriodicalId":51073,"journal":{"name":"Journal of Aging and Physical Activity","volume":" ","pages":"1-9"},"PeriodicalIF":1.4,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142928729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explored People Living with Dementia's (PLWD) adherence to a Tai Chi exercise program and its effects on their QoL. The study included assessment of factors affecting adherence to a Tai Chi exercise intervention, causes of nonadherence, and effect of adherence on PLWD's QoL.Methods: This study was part of a randomized controlled trial where 41 community-dwelling PLWD received a Tai Chi exercise intervention in addition to usual care for 20 weeks. The measures used in this study included PLWD's QoL, global cognitive function, moderate physical activity, intention and confidence to attend classes, record of PLWD's and their carers' health conditions, and percentages of PLWD's Tai Chi class attendance and home practice during the intervention phase. Multiple linear regression, bivariate correlation, and independent sample t-test analyses were conducted to evaluate associations between these variables.Results: PLWD's overall percentage of class attendance, M (SD) = 69.19 (29.95), demonstrated high adherence.
