Background Prescription of resistance training (RT) exercises is an essential aspect of management for knee osteoarthritis (OA). However, whether patients with knee OA who are randomly assigned to receive RT simply substitute RT for other modes of physical activity remains unclear. Objective The aim of this study was to determine the effect of a structured RT intervention on overall levels of moderate- and vigorous-intensity physical activity (MVPA) in patients with early-onset knee OA. The study compared patients with early-onset OA who participated in an RT program, those who participated in a self-management (SM) program, and those who participated in both RT and SM. Because participants randomly assigned to receive the RT intervention may simply switch activity modes, resulting in little net effect, we assessed total MVPA in addition to tracking changes in strength (force-generating capacity). Design and Intervention This study was a randomized controlled trial comparing the effectiveness of SM alone, RT alone, and combined RT+SM on MVPA in patients with early OA of the knee. Setting The study was conducted on a university campus, with patient recruitment from the local community. Participants The participants in this study were 171 patients (74% women, 26% men) with knee OA. They had a mean age of 55.1 (SD=7.1) years, a mean body mass index of 27.6 (SD=4.2) kg/m2, and radiographic status of grade II OA (and no higher) in at least one knee, as defined by the Kellgren and Lawrence classification. They wore an accelerometer while awake (X̄=14.2 [SD=2.2] hours) for 5 to 7 contiguous days (X̄=6.8 [SD=0.5] days) at baseline and at 3 and 9 months of intervention. Results The participants engaged in MVPA a mean of 26.2 (SD=19.3) minutes per day at baseline. Both groups significantly increased their MVPA from baseline to 3 months (RT group by 18% [effect size (d)=0.26]; SM group by 22% [effect size (d)=0.25]), but only the RT group sustained those changes at 9 months (RT group maintained a 10% increase [effect size (d)=0.15]; SM group maintained a 2% increase [effect size (d)=0.03]). A significant group × time interaction for MVPA indicated that the RT group maintained higher MVPA levels than the SM group. Limitations Lack of direct measures of energy expenditure and physical function was a limitation of the study. Conclusions Patients with early-onset OA of the knee can engage in an RT program without sacrificing their overall MVPA levels. These results support the value of RT for management of knee OA.

Background:Promoting physical activity (PA) in low- and middle-income countries is an important public health topic as well as a challenge for practice. This study aimed to assess the effect of a school-based intervention on different PA-related variables among students.Methods:This cluster-randomized-controlled trial included 548 students in the intervention group and 537 in the control group (11–18 years-old) from 6 schools in neighborhoods with low Human Development Index (0.170–0.491) in Fortaleza, Brazil. The intervention included strategies focused on training teachers, opportunities for PA in the school environment and health education. Variables measured at baseline and again at the 4-months follow-up included the weekly time in different types of moderate-to-vigorous PA (MVPA), preference for PA during leisure-time, PA behavioral change stage and active commuting to school. Generalized linear models and binary logistic regressions were used.Results:An intervention effect was found by increasing the weekly time in MVPA (effect size = 0.17), popular games (effect size = 0.35), and the amount of PA per week (effect size = 0.27) among students (all P < .05).Conclusions:The intervention was effective in promoting improvements in some PA outcomes, but the changes were not sufficient to increase the proportion of those meeting PA recommendations.

BACKGROUND Current guidelines emphasize an active lifestyle in the management of knee osteoarthritis (OA), but up to 90% of patients with OA are inactive. In a previous study, we demonstrated that an 8-week physiotherapist (PT)-led counseling intervention, with the use of a Fitbit, improved step count and quality of life in patients with knee OA, compared with a control. OBJECTIVE This study aimed to examine the effect of a 12-week, multifaceted wearable-based program on physical activity and patient outcomes in patients with knee OA. METHODS This was a randomized controlled trial with a delay-control design. The immediate group (IG) received group education, a Fitbit, access to FitViz (a Fitbit-compatible app), and 4 biweekly phone calls from a PT over 8 weeks. Participants then continued using Fitbit and FitViz independently up to week 12. The delay group (DG) received a monthly electronic newsletter in weeks 1 to 12 and started the same intervention in week 14. Participants were assessed in weeks 13, 26, and 39. The primary outcome was time spent in daily moderate-to-vigorous physical activity (MVPA; in bouts ≥10 min) measured with a SenseWear Mini. Secondary outcomes included daily steps, time spent in purposeful activity and sedentary behavior, Knee Injury and OA Outcome Score, Patient Health Questionnaire-9, Partners in Health Scale, Theory of Planned Behavior Questionnaire, and Self-Reported Habit Index. RESULTS We enrolled 51 participants (IG: n=26 and DG: n=25). Compared with the IG, the DG accumulated significantly more MVPA time at baseline. The adjusted mean difference in MVPA was 13.1 min per day (95% CI 1.6 to 24.5). A significant effect was also found in the adjusted mean difference in perceived sitting habit at work (0.7; 95% CI 0.2 to 1.2) and during leisure activities (0.7; 95% CI 0.2 to 1.2). No significant effect was found in the remaining secondary outcomes. CONCLUSIONS A 12-week multifaceted program with the use of a wearable device, an app, and PT counseling improved physical activity in people with knee OA.

Background:The aim was to assess the feasibility and preliminary efficacy of a community-based physical activity (PA) intervention targeting mothers and daughters.Methods:A randomized controlled trial of 48 primary school-aged girls and their 40 mothers were randomized to (i) Mothers And Daughters Exercising for Life (MADE4Life) (n = 21 mothers, n = 25 daughters) or (ii) wait-list control (n = 19 mothers, n = 23 daughters). The 8-week program involved 8 sessions; 25-minute separate mothers and daughters education sessions and 60-minutes PA together. Assessments were at baseline, postintervention and 3-month postintervention. Primary outcome measure was daughters’ moderateto-vigorous physical activity (MVPA) (accelerometer). Secondary outcomes included accelerometer-assessed light/moderate/vigorous PA, BMI, waist circumference, body composition, blood pressure, resting heart rate, sedentary behaviors and mothers’ self-reported PA, parenting measures, and cognitions. Intention-to-treat analysis used linear mixed models.Results:Recruitment and retention goals were exceeded. Attendance rates, program acceptability and satisfaction were high. There was no significant group-by-time effect for daughters’ %MVPA (–0.08; 95%CI –1.49, 1.33, d = –0.03) or other secondary outcomes for girls (postintervention range d = 0.01 to –0.46). Significant intervention effects were found for mothers’ %VPA (P = .04, d = 0.25) and role modeling (P = .02, d = 0.66).Conclusion:MADE4Life was both feasible and acceptable. Although very small effect sizes were found for the daughters, significant changes were seen for mothers (d = 0.25 to 0.66). Future fully powered trials targeting PA in mothers and daughters is warranted.

Objective: The aim of this study was to investigate the effect of adding four weeks preoperative progressive resistance training (PRT) to four weeks postoperative PRT on patient function, muscle strength, and other outcomes 12 months after total knee arthroplasty (TKA). Design: Twelve-month follow-up data from a previously published randomized controlled trial. Setting: Aarhus University Hospital, Silkeborg Regional Hospital, and Aarhus University. Subjects: A total of 59 patients scheduled for TKA were enrolled in a single-blinded, clinical randomized controlled trial. Interventions: Participants were randomized to preoperative PRT (intervention group) or to a control group who “lived as usual” the last four weeks before TKA. The intervention group completed four weeks preoperative and four weeks postoperative PRT, whereas the control group only completed four weeks postoperative PRT. Main follow-up measures were as follows: the 30-second Chair Stand Test (primary outcome), Timed Up and Go Test, walk tests, knee extensor, and knee flexor muscle strength and patient-reported outcomes. Statistical analyses were performed according to the intention-to-treat principle. Results: No significant group differences were observed for the primary outcome 30-second Chair Stand Test (4.0 repetitions versus 2.4 repetitions, P = 0.067) or for other functional performance outcomes. The intervention group had significantly higher weight-normalized knee extensor muscle strength (0.5 Nm/kg versus 0.2 Nm/kg, P = 0.002) and knee flexor muscle strength (0.3 Nm/kg versus 0.2 Nm/kg, P = 0.042) in the operated leg when compared to the control group. No significant group differences for patient-reported outcomes. Conclusion: The study supports the use of short-term high-intensity resistance training before TKA as it induces a long-lasting effect on muscle strength, while it may have no discernible effect on functional performance.
