BACKGROUND Current evidence indicates physical activity wearables could support persons with knee osteoarthritis (OA) to be more physically active. Recent evidence also identifies, however, some persons with arthritis experience guilt or worry while using a wearable if they are not as active as they feel they should be. Questions remain around how persons with knee OA experience benefits or downsides in using a wearable in their everyday lives. Better understanding is needed if wearables are to be incorporated in arthritis self-management in ways that are ethically aware. OBJECTIVE Using an ethics lens, describe a range of experiences from persons with knee OA who used a wearable during a physical activity counselling intervention study. METHODS This is a secondary analysis of qualitative interviews (60-90 mins) nested within a randomized controlled trial (RCT). Guided by phenomenography, we explored the experiences of persons with knee OA, following participation in a physical activity counselling intervention. The intervention consisted of a 1.5-hour education session about physical activity, using a Fitbit Flex, and receiving 4 biweekly phone calls for activity counselling with a study physiotherapist (PT) in an 8-week period. All PTs were trained in the Brief Action Planning approach, whereby they guided participants to identify activity goals, develop an action plan, and identify barriers and solutions. Benefits or downsides experienced in participants’ relationships with themselves or the study PT when using the wearable were identified using a relational ethics lens. RESULTS Interviews with 21 participants (12 females, 9 males) aged 40-82 years were analyzed. Education ranged from high school graduate (n=4) to bachelor’s degree or above (n=11). Three categories of description were identified: 1) Participants experienced their wearable as a motivating or nagging influence to be more active, depending on how freely they were able to make autonomous choices about physical activity in their everyday lives; 2) Some participants felt a sense of accomplishment from seeing progress in their wearable data, which fuelled motivation. One participant experienced negative emotions (e.g., self-blame) if his wearable data indicated physical activity goals were not met; 3) For some participants, sharing wearable data helped to build mutual trust in their relationship with the study PT. They also expressed, however, there was potential for sharing wearable data to undermine this trust, particularly if this data was inaccurate. CONCLUSIONS To our knowledge, this is the first qualitative study that uses a relational ethics lens to explore how persons with arthritis experienced changes in their relationship with a health professional when using a wearable during research participation. Findings also provide an early glimpse into positive and negative emotional impacts of using a wearable that can be experienced by participants with knee OA when participating in an RCT to support physical activity.

Cardiovascular fitness is linked to better executive functions, preserved gait speed, and efficient cortical activity. Older adults with cardiovascular risk factors (CVRFs) typically show poor cognitive performance, low physical fitness, and altered brain functioning compared with healthy individuals. In the current study, the impact of regular physical activity on cognition, locomotion, and brain functions was explored in a cohort of older adults with low or high CVRFs. Cortical activation of the frontal areas was investigated using functional Near-Infrared Spectroscopy (fNIRS) at baseline, at 6 months and at 12 months. Evoked cortical response and behavioral performance were assessed using the dual-task walking paradigm, consisting of three conditions: single cognitive task (2-back task), single walking task (walking), and dual-task (2-back whilst walking). Results show greater task-related cortical response at baseline in individuals with high CVRFs compared to those with low CVRFs. Moreover, participants with high CVRFs benefitted the most from participating in regular physical activity, as their cortical response decreased at the 12-month follow-up and became comparable to that of participants with low CVRFs. These changes were observed in conjunction with improved cognitive performance and stable gait speed throughout the 12-month period in both groups. Our findings provide evidence that participation in regular physical activity may be especially beneficial in individuals with CVRFs by promoting brain and cognitive health, thus potentially contributing to prevention of cognitive decline. Future research may explore whether such effects are maintained in the long-term in order to design ad-hoc interventions in this specific population.

BACKGROUND: Prolonged sitting in desk-based office workers is found to be associated with increased cardiometabolic risk and poor cognitive performance. Technology-based physical activity (PA) interventions using smartphone applications (SmPh app) to promote PA levels might be effective in reducing cardiometabolic risk among sedentary population but the evidence remains inconclusive. OBJECTIVE: The objective is to investigate the effects of a technology-based PA intervention compared to PA education with a worksite manual or no intervention on PA levels, cardiometabolic risk, cognitive performance, and work productivity among desk-based employees. METHOD: A three-arm clustered randomized trial will be conducted. The study will be conducted among various administrative offices of a multifaceted university in India. Desk-based employees aged between 30 and 50 years (n = 159; 53 in each arm) will be recruited. Employees from various constituent institutions (clusters) of the university will be randomized into one of the three following groups - SMART: SmPh app-driven break reminders (visual exercise prompts) plus pedometer-based step intervention, TRADE: worksite PA education with a manual plus American College of Sports Medicine guided PA prescription, or CONTROL: usual work group. At baseline and after the 1st, 3rd and 6th month of the trial period, accelerometer-measured sitting time and PA levels, cardiometabolic risk (fasting blood glucose, triglycerides, insulin, blood pressure, heart rate variability, functional capacity, and subcutaneous fat), cognitive performance (executive function), sickness absenteeism and work limitations will be assessed by a blinded assessor. Therapist delivering interventions will not be blinded. CONCLUSION: This trial will determine whether a combined SmPh-app and pedometer-based intervention is more effective than education or no intervention in altering PA levels, cardiometabolic risk and cognitive performance among desk-based employees in India. This study has the potential to foster institutional recommendations for using SmPh-based technology and pedometers to promote PA at work.
