Abstract BACKGROUND AND AIMS Despite the benefits reported by the implementation of exercise during dialysis, currently it is not a clinical routine. Non-immersive virtual reality (VR) is a feasible option to exercise and in a short pilot study of intadialysis VR exercise improved physical function (PF), Health-related quality of life (HRQoL) and physical activity (PA). The objective of this research was to investigate if a 12-weeks non-immersive VR exercise program intradialysis improves PF and PA. METHODS This was a crossover randomized controlled trial. Participants were randomized in a control-VR group (CVR) or VR-control group (VRC). There were two consecutive periods of 12 weeks, one control and one exercise period. The CVR started with a control period and followed by the exercise period, and the VRC did the opposite. PF and PA were assessed at four time points: baseline, 12, 24 and 36 weeks. The functional tests administered included the Short Physical Performance Battery (SPPB), gait speed in 4 meters, Timed Up-and-Go (TUG), balance with the one-legged stance test (OLST), Sit-to-Stand 10 (STS10) and Sit-to-Stand 60 (STS-60), 6 minute walking test (6MWT). Human Activity Profile (HAP) was used to assess PA level. Intradialysis exercise consisted of a video game adapted to dialysis: Treasure hunting. It is a non-immersive VR game in which the patient must catch some objectives avoiding obstacles by moving the lower limbs. The exercise session lasted from 20 to 40 minutes. Intensity was checked through the rate of perceived exertion (RPE). A mixed model of repeated measures were used to assess the effect of the intervention. RESULTS 47 subjects were included in the study, 22 subjects (median age 73.5 years; 13 males) in the CVR and 25 subjects (median age 72 years, 15 males) in the VRC. At 24 weeks we tested 33 subjects and at 36 weeks 31 patients were tested. The results of all functional tests improved after the exercise program (Gait speed in 4 meters -0.16 seconds, 95% CI -0.1- -0.2 VRC and -0.12 seconds, 95% IC -0.06--0.17 CVR; TUG -1.8 seconds, 95% CI -1.2--2.5 VRC and -1.3 seconds, 95% CI 0.1--2.7 CVR; OLST 6.2 seconds, 95% CI 2.6-9.8 VRC and 8.1 seconds, 95% CI 4.2-12.0 CVR; STS-10 -5.6 seconds, 95% CI -3.5--7.8 VRC and -6.0 seconds, 95% CI -4.0--7.9 CVR; and 6MWT 105.4 meters, 95% CI 76.2-134.6 VRC and CVR 59.5 meters, 95% CI 34.5-84.5). The VRC showed a significant increase in HAP (9.2, 95% CI 6.4-12.0) after the 12 weeks of exercise program. The CVR did not change during the first 12 weeks of no exercise, but showed a significant increase at 24 weeks after the end of the exercise program in HAP (7.4, 95% CI 3.8-11.0). The follow-up of 12 weeks after the end of the program in the VRC showed a significant decrease in function in the following tests (Gait speed in 4 meters -0.13seconds, 95% CI 0.08--0.18; STS-10 -1.4 seconds, CI 95% 0.11-2.65; and 6MWT -66.4 meters, 95% CI 43.5-89.2). During the follow-up period, at 24 weeks, the VRC showed a significant decrease in HAP (-7.7, 95% CI -11.0--4.4), there was no further decrease at 36 weeks. At 36 weeks, after 12 weeks of follow-up, participants in the CVR presented a significant decrease in HAP (-7.2, 95% CI -10.5--4.0). CONCLUSIONS A non-immersive VR exercise program during intradialysis improves PF and PA and HRQoL. Exercise benefits are not maintained after 12 weeks of follow-up.

Abstract Background Many students in Germany do not meet recommended amounts of physical activity. In order to promote physical activity in students, web-based interventions are increasingly implemented. Yet, data on effectiveness of web-based interventions in university students is low. Our study aims at investigating a web-based intervention for students. The intervention is based on the Health Action Process Approach (HAPA), which discriminates between processes of intention formation (motivational processes) and processes of intention implementation (volitional processes). Primary outcome is change in physical activity; secondary outcomes are motivational and volitional variables as proposed by the HAPA as well as quality of life and depressive symptoms. Methods A two-armed randomized controlled trial (RCT) of parallel design is conducted. Participants are recruited via the internet platform StudiCare (www.studicare.com). After the baseline assessment (t1), participants are randomized to either intervention group (immediate access to web-based intervention) or control group (access only after follow-up assessment). Four weeks later, post-assessment (t2) is performed in both groups followed by a follow-up assessment (t3) 3 months later. Assessments take place online. Main outcome analyses will follow an intention-to-treat principle by including all randomized participants into the analyses. Outcomes will be analysed using a linear mixed model, assuming data are missing at random. The mixed model will include group, time, and the interaction of group and time as fixed effects and participant and university as random effect. Discussion This study is a high-quality RCT with three assessment points and intention-to-treat analysis meeting the state-of-the-art of effectiveness studies. Recruitment covers almost 20 universities in three countries, leading to high external validity. The results of this study will be of great relevance for student health campaigns, as they reflect the effectiveness of self-help interventions for young adults with regard to behaviour change as well as motivational and volitional determinants. From a lifespan perspective, it is important to help students find their way into regular physical activity. Trial registration The German clinical trials register (DRKS) DRKS00016889.

BACKGROUND: Impaired mobility is related to low physical activity (PA) levels observed after stroke. Therapeutic approaches, such as task-specific circuit training (TSCT), used to improve mobility in individuals with stroke, could also improve PA levels. OBJECTIVE: To investigate the efficacy of TSCT, focused on both upper (UL) and lower (LL) limbs, in improving PA levels and mobility (primary outcomes), as well as muscle strength, exercise capacity, and quality of life (secondary outcomes) in subjects with stroke. METHODS: A randomized controlled trial with 36 subjects with chronic stroke was conducted. Experimental group: TSCT, involving both UL and LL. Control group: global stretching, memory exercises, and education sessions. Both groups received 60 minute sessions/week over 12 weeks. Outcomes were measured at baseline, post-intervention and 16 week follow-up. RESULTS: No changes were found for primary and secondary outcomes (0.11≤p≤0.99), except for quality of life, which improved in the experimental group post-intervention and 16 week follow-up (p = 0.02). CONCLUSION: TSCT focused on both UL and LL was not effective on PA levels and mobility of individuals with chronic stroke, however, improvements in quality of life were observed. Since this is the first study to investigate this combined training aimed at improving PA levels, future studies are necessary to better understand the impact of this type of intervention.

Children With Intellectual Disability

Background Childhood obesity accompanied by lower levels of health-related physical fitness (HRPF) is a major threat to public health both internationally and locally. Children with intellectual disability, especially adolescents, have a higher risk of being overweight/obese and having poor HRPF levels. Therefore, more interventions are needed to help this population attain their optimal health levels. However, there has been relatively limited research on this population compared with on their typically developing peers. Objective The proposed study aims to fill this knowledge gap by developing and examining the success of a physical activity (PA) intervention for the target population. Methods The proposed study will be a 12-week, school-based randomized controlled trial. The participants (N=48) will be recruited from special schools for students with mild intellectual disability and then randomly allocated to either the intervention group (IG) or the wait-list control group (CG). During the intervention period, the participants in the IG will receive a fun game–based moderate-to-vigorous PA (MVPA) training program (2 sessions/week, 60 minutes/session, for a total of 24 sessions). The intensity of the activities will increase in a progressive manner. Participants in the CG will receive no program during the study period, but the same PA program will be provided to them after the completion of the study. To observe and evaluate the sustaining effects of the intervention, follow-up testing will be scheduled for the participants 12 weeks after the intervention concludes. The study outcomes will include primary outcomes (obesity- and fitness-related outcomes) and a secondary outcome (blood pressure). All of the measurements will be taken at 3 time points. After the follow-up tests, the same PA training program will be provided to the participants in the CG. Results This study is ongoing. The participants were recruited from October 2020 to November 2020. The total duration of the study is 13 months. Study results are expected at the end of 2021. Conclusions The proposed study is expected to reduce obesity and improve HRPF levels in children with intellectual disability. If proven effective, the intervention will be made accessible to more special schools and mainstream schools with students with intellectual disability. Furthermore, the study can serve as an example for international researchers, policy makers, and members of the public who are seeking to tackle the problem of obesity and poor HRPF among children with intellectual disability.

The Impact

Aim: To assess the impact of a multistrategy intervention designed to improve teachers’ implementation of a school physical activity (PA) policy on student PA levels. Methods: A cluster-randomized controlled trial was conducted in 12 elementary schools. Policy implementation required schools to deliver 150 minutes of organized PA for students each week via physical education, sport, or class-based activities such as energizers. Schools received implementation support designed using the theoretical domains framework to help them implement the current policy. Results: A total of 1,502 children in kindergarten to grade 6 participated. At follow-up compared with control, students attending intervention schools had, measured via accelerometer, significantly greater increases in school day counts per minute (97.5; 95% confidence interval [CI], 64.5 to 130.4; P < .001) and moderate to vigorous physical activity (MVPA) (3.0; 95% CI, 2.2–3.8, P < .001) and a greater decrease in sedentary time (−2.1; 95% CI, −3.9 to −0.4, P = .02) per school day. Teachers in intervention schools delivered significantly more minutes (36.6 min) of PA to their students at follow-up (95% CI, 2.7–70.5, P = .04). Conclusions: Supporting teachers to implement a PA policy improves student PA. Additional strategies may be needed to support teachers to implement activities that result in larger gains in student MVPA.

BACKGROUND The McMaster Optimal Aging Portal (the Portal) was launched in 2014 as a knowledge translation (KT) tool to increase access to evidence-based health information. OBJECTIVE The purpose of this study was to understand if and how dissemination of mobility information through the Portal impacts physical activity (PA) in older adults. METHODS In this randomized controlled trial, participants (n=510) were assigned to a 12-week mobility-focused KT intervention or self-serve control group. The intervention included weekly email alerts and a study-specific social media hashtag linking to mobility-focused Portal materials. The control group was able to access the Portal on their own but did not receive targeted KT strategies. Participants completed questionnaires (including the Rapid Assessment of Physical Activity to quantify PA) at baseline, end of the study, and 3-month follow-up. RESULTS Participants were predominantly female (430/510, 84.3%), mean age 64.7 years, with no baseline differences between groups. Over half (277/510, 54.3%) of the participants were classified as “active” at baseline. There was no significant between-group difference in the PA category. Overall, both groups increased their PA with improvements maintained at 3-month follow-up (<i>P</i>&lt;.001). In planned subgroup analyses, the KT intervention had a significant effect for those with poor or fair baseline self-rated health (<i>P</i>=.03). CONCLUSIONS No differences were found between those who received the targeted intervention and a control group with self-serve access to the Portal, except in subgroups with low self-rated health. Both groups did report increases in PA that were sustained beyond participation in a research study. Findings suggest that different KT strategies may be needed for different types of users, with more intense interventions being most impactful for certain groups (ie, those with lower self-rated health).
