Exercise physiologists use of pain neuroscience education for treating knee osteoarthritis: A qualitative interview study

Objectives: To explore how Australian exercise physiologists (EPs) utilise pain neuroscience education (PNE) in their management of patients with knee osteoarthritis. Methods: A semi-structured interview concerning a knee osteoarthritis vignette was designed to understand each participant's beliefs about physical activity, pain, injury and coping strategies and quantify their use of pain neuroscience concepts. Themes were derived from pre-determined pain target concepts as well as others that emerged from thematic analysis. Results: Thirty EPs (57% male, mean clinical experience 7 years (SD 7.1) participated in the semi-structured interviews. 13 themes emerged. EPs primarily focussed on: (1) active treatment strategies are better than passive, (2) pain and tissue damage rarely relate, and (3) learning about pain can help individuals and society. Other themes included the use of biomedical-based education, pain during exercise and delivery of PNE. Underutilised themes included the role of the brain in pain, validation that pain is real and personal, the concept of danger sensors as opposed to pain sensors, and pain depends on the balance between safety and danger. Conclusion: EPs primarily advised on active treatment approaches (e.g. exercise and self-management). Quality of care is likely to improve through increasing focus on the systemic benefits of exercise in overcoming psychological barriers (e.g. fear avoidance and pain catastrophising) that may prevent exercise treatment engagement. Broadening PNE to reconceptualise knee osteoarthritis pain as a sign of an overprotective nervous system, rather than structural damage, may facilitate greater patient engagement in exercise therapies, thus improving patient outcomes

Resistance Training and High-intensity Interval Training Improve Cardiometabolic Health in High Risk Older Adults: A Systematic Review and Meta-anaylsis

Progressive resistance training (PRT) and high-intensity interval training (HIIT) improve cardiometabolic health in older adults. Whether combination PRT+HIIT (COMB) provides similar or additional benefit is less clear. This systematic review with meta-analysis of controlled trials examined effects of PRT, HIIT and COMB compared to non-exercise control in older adults with high cardiometabolic risk. Databases were searched until January 2021, with study quality assessed using the PEDro scale. Risk factor data was extracted and analysed using RevMan V.5.3. We analysed 422 participants from nine studies (7 PRT, n=149, 1 HIIT, n=10, 1 COMB, n=60; control n=203; mean age 68.1±1.4 years). Compared to control, exercise improved body mass index (mean difference (MD)-0.33 [-0.47,-0.20], p≤0.0001), body fat% (standardised mean difference (SMD)-0.71 [-1.34,-0.08], p=0.03), aerobic capacity (SMD 0.41 [0.05, 0.78], p=0.03), low-density lipoprotein (SMD-0.27 [-0.52,-0.01], p=0.04), and blood glucose (SMD-0.31 [-0.58,-0.05], p=0.02). Therefore, PRT, HIIT and COMB can improve cardiometabolic health in older adults with cardiometabolic risk. Further research is warranted, particularly in HIIT and COMB, to identify the optimal exercise prescription, if any, for improving older adults cardiometabolic health. (PROSPERO: CRD42019128527)

Are Improvements in Pain Neurophysiology Knowledge Following Pain Science Education Associated with Improved Outcomes in People with Chronic Pain?: A Systematic Review and Meta-analysis

Objective: This systematic review and meta-analysis aimed to determine the association between changes in patients' pain knowledge after pain science education (PSE) with treatment outcomes in people with chronic pain. Methods: Six electronic databases and 2 clinical trial registries were searched from inception to September 15, 2021 for studies where participants received PSE and had their pain knowledge and clinical outcomes assessed before and after PSE. Meta-analyses were performed for pain intensity, kinesiophobia, and pain catastrophizing. Physical function and quality of life outcomes were synthesized narratively. Risk of bias was assessed using the Cochrane tool for nonrandomized studies and the quality of evidence was assessed using GRADE. Results: Fourteen studies (n=1500 participants) were included. Meta-analyses revealed no significant associations between short-term (<12 wk) changes in pain neurophysiology knowledge with changes in pain intensity (n=1075, r=-0.01, 95% CI =-0.14 to 0.13, very low certainty), kinesiophobia (n=152, r=0.02, 95% CI =-0.27 to 0.24, very low certainty) and pain catastrophizing (n=976, r=-0.03, 95% CI=-0.18 to 0.11, low certainty). No significant associations were found between short-term changes in pain neurophysiology knowledge and physical function or quality of life either. Discussion: These findings do not support a short-term association between improvements in pain neurophysiology knowledge and better treatment outcomes in people with chronic pain. Increased understanding of how PSE works, as well as better ways to measure it, may help clinicians deliver more targeted education to help patients reconceptualize pain and promote engagement in active treatment strategies (eg, exercise)

An exploratory study to investigate the association between age, physical activity, femoral trochlear cartilage thickness and biomarkers of tissue metabolism in adult males

Purpose: To investigate the association between age, physical activity, femoral trochlear cartilage thickness and biomarkers of tissue metabolism in a cross-sectional sample of adult males. This study utilizes several emerging biomarkers that have been associated with early joint degenerative changes; serum COMP (cartilage oligomeric matrix protein), HA (hyaluronan) and lubricin. Methods: Eighty-one males (age: mean (range): 43(18–70) years; body mass index: 25.2 (21.0–30.6) kg/m2) volunteered. Resting serum COMP, HA and lubricin concentrations were determined via commercially available enzyme-linked immunosorbent assay (ELISA) and femoral trochlear cartilage thickness via supra-patellar ultrasound imaging. Physical activity levels were assessed using questionnaires. Statistical analyses were performed using correlation and regression analyses. Results: Age was correlated with lateral trochlear cartilage thickness (r = − 0.372; p 0.05). Conclusion: This study indicates that older age may be associated with thinner lateral trochlear cartilage and higher cartilage turnover. Being physically active may also be positive for lateral trochlear cartilage thickness. However, overall, both age and physical activity level only account for a small amount of the variability in cartilage thickness and serum biomarkers

The AgeWell study of behavior change to promote health and wellbeing in later life: study protocol for a randomized controlled trial.

This is the final version of the article. Available from Biomed Central via the DOI in this record.BACKGROUND: Lifestyle factors playing a role in the development of late-life disability may be modifiable. There is a need for robust evidence about the potential for prevention of disability through behavior change interventions. METHODS/DESIGN: This feasibility study involves the development, implementation and initial testing of a behavior change intervention in a naturalistic setting. A small-scale randomized controlled trial (RCT) will investigate the implementation of a goal-setting intervention aimed at promoting behavior change in the domains of physical and cognitive activity in the context of a community resource center for over-50s. Healthy older participants attending the center (n = 75) will be randomized to one of three conditions: control (an interview involving a general discussion about the center); goal-setting (an interview involving identification of up to five personal goals in the domains of physical activity, cognitive activity, diet and health, and social engagement); or goal-setting with mentoring (the goal-setting interview followed by bi-monthly telephone mentoring). All participants will be reassessed after 12 months. Primary outcomes are levels of physical and cognitive activity. Secondary outcomes address psychosocial (self-efficacy, mood, quality of life), cognitive (memory and executive function), and physical fitness (functional and metabolic) domains. Cost-effectiveness will also be examined. DISCUSSION: This study will provide information about the feasibility of a community-based lifestyle intervention model for over-50s and of the implementation of a goal-setting intervention for behavior change, together with initial evidence about the short-term effects of goal-setting on behavior.

Creaky knees: Is there a reason for concern? A qualitative study of the perspectives of people with knee crepitus

Objective: Crepitus is a feature of osteoarthritis that may affect one's participation in exercise. An informed understanding is required of the perceptions that people have of their knee crepitus and how it affects their exercise behaviours. This study aims to investigate the role that crepitus may play in beliefs about exercise and knee health. Methods: Focus group and individual interviews were conducted online with participants who had knee crepitus. The transcripts were thematically analysed through an inductive approach. Results: Five main themes were identified from 24 participants: (1) individual variation of, (2) occurrence of, (3) meaning of knee crepitus, (4) attitudes and exercise behaviours regarding crepitus, and (5) knowledge deficits and needs concerning crepitus during exercise. The variety of crepitus sounds described occurred with a range of exercises or after inactivity. For those already with osteoarthritis or other symptoms, crepitus was of less concern than symptoms such as pain. Most participants had not ceased exercise but may have modified movement due to crepitus and associated symptoms; some had increased intentional strength training to try alleviating it. Participants agreed that more understanding about the processes causing crepitus and what exercise was safe for knee health would be beneficial. Conclusion: Crepitus does not appear to be a major cause of concern for people who experience it. However, it is a factor that influences exercise behaviours as is pain. If health professionals could guide people with concerns about their crepitus, they may be more confident in exercising to benefit their joint health

The Agewell trial: a pilot randomised controlled trial of a behaviour change intervention to promote healthy ageing and reduce risk of dementia in later life.

This is the final version of the article. Available from BioMed Central via the DOI in this record.BACKGROUND: Lifestyle factors represent prime targets for behaviour change interventions to promote healthy ageing and reduce dementia risk. We evaluated a goal-setting intervention aimed at promoting increased cognitive and physical activity and improving mental and physical fitness, diet and health. METHODS: This was a pilot randomised controlled trial designed to guide planning for a larger-scale investigation, provide preliminary evidence regarding efficacy, and explore feasibility and acceptability. Primary outcomes were engagement in physical and cognitive activity. Participants aged over 50 living independently in the community were recruited through a community Agewell Centre. Following baseline assessment participants were randomly allocated to one of three conditions: control (IC) had an interview in which information about activities and health was discussed; goal-setting (GS n = 24) had an interview in which they set behaviour change goals relating to physical, cognitive and social activity, health and nutrition; and goal-setting with mentoring (GM, n = 24) had the goal-setting interview followed by bi-monthly telephone mentoring. Participants and researchers were blinded to group assignment. Participants were reassessed after 12 months. RESULTS: Seventy-five participants were randomised (IC n = 27, GS n = 24, GM n = 24). At 12-month follow-up, the two goal-setting groups, taken together (GS n = 21, GM n = 22), increased their level of physical (effect size 0.37) and cognitive (effect size 0.15) activity relative to controls (IC n = 27). In secondary outcomes, the two goal-setting groups taken together achieved additional benefits compared to control (effect sizes ≥ 0.2) in memory, executive function, cholesterol level, aerobic capacity, flexibility, balance, grip strength, and agility. Adding follow-up mentoring produced further benefits compared to goal-setting alone (effect sizes ≥ 0.2) in physical activity, body composition, global cognition and memory, but not in other domains. Implementation of the recruitment procedure, assessment and intervention was found to be feasible and the approach taken was acceptable to participants, with no adverse effects. CONCLUSIONS: A brief, low-cost goal-setting intervention is feasible and acceptable, and has the potential to achieve increased activity engagement.

Identifying predictors of transition to a care home for people with dementia: findings from the IDEAL programme

\ua9 2024 The Author(s). Published by Informa UK Limited, trading as Taylor &amp; Francis Group.Objectives: This study investigates factors associated with the person with dementia and the caregiver to identify those associated with an increased risk of transition to a care home. Method: IDEAL data were collected at baseline and at 12- and 24-month follow-up for 1545 people with dementia and 1305 caregivers. Modified Poisson regressions with an offset for ‘person years at risk’ were used. Person with dementia factors explored were personal characteristics, cognition, health, self- and informant-rated functional ability, and neuropsychiatric symptoms. Caregiver factors explored were personal characteristics, stress, health, and quality of the dyadic relationship. Results: A 5% people moved into care. Risk of moving into a care home was higher among people with dementia who were ≥80 years, among people with Parkinson’s disease dementia or dementia with Lewy bodies, and among those without a spousal caregiver. Poorer cognition and more self-rated or informant-rated functional difficulties increased the risk of moving into care. Conclusion: Factors related to increased dementia severity and greater disability are the primary influences that place people with dementia at greater risk of moving into a care home. Strategies that help to maintain everyday functional ability for people with dementia could help delay people with dementia moving into care

Comorbid health conditions and their impact on social isolation, loneliness, quality of life, and well-being in people with dementia: longitudinal findings from the IDEAL programme

\ua9 2024, The Author(s).Background: Most people with dementia have multiple health conditions. This study explores (1) number and type of health condition(s) in people with dementia overall and in relation to age, sex, dementia type, and cognition; (2) change in number of health conditions over two years; and (3) whether over time the number of health conditions at baseline is related to social isolation, loneliness, quality of life, and/or well-being. Methods: Longitudinal data from the IDEAL (Improving the experience of Dementia and Enhancing Active Life) cohort were used. Participants comprised people with dementia (n = 1490) living in the community (at baseline) in Great Britain. Health conditions using the Charlson Comorbidity Index, cognition, social isolation, loneliness, quality of life, and well-being were assessed over two years. Mixed effects modelling was used. Results: On average participants had 1.8 health conditions at baseline, excluding dementia; increasing to 2.5 conditions over two years. Those with vascular dementia or mixed (Alzheimer’s and vascular) dementia had more health conditions than those with Alzheimer’s disease. People aged ≥ 80 had more health conditions than those aged &lt; 65 years. At baseline having more health conditions was associated with increased loneliness, poorer quality of life, and poorer well-being, but was either minimally or not associated with cognition, sex, and social isolation. Number of health conditions had either minimal or no influence on these variables over time. Conclusions: People with dementia in IDEAL generally had multiple health conditions and those with more health conditions were lonelier, had poorer quality of life, and poorer well-being
