CONCLUSIONS Utilizing a consumer-based wearable activity tracker as either the primary component of an intervention or as part of a broader physical activity intervention has the potential to increase physical activity participation .
BACKGROUND The range of benefits associated with regular physical activity participation is irrefutable .
Despite the well-known benefits , physical inactivity remains one of the major contributing factors to ill-health throughout industrialized countries .
Traditional lifestyle interventions such as group education or telephone counseling are effective at increasing physical activity participation ; however , physical activity levels tend to decline over time .
Consumer-based wearable activity trackers that allow users to objective ly monitor activity levels are now widely available and may offer an alternative method for assisting individuals to remain physically active .
OBJECTIVE This review aim ed to determine the effects of interventions utilizing consumer-based wearable activity trackers on physical activity participation and sedentary behavior when compared with interventions that do not utilize activity tracker feedback .
Assessing the Impact of a Novel Smartphone Application Compared With Standard Follow-Up on Mobility of Patients With Knee Osteoarthritis Following Treatment With Hylan G-F 20: A Randomized Controlled Trial
Background Osteoarthritis ( OA ) is a leading cause of disability in the United States . Although no disease-modifying therapies exist , patients with knee OA who increase walking may reduce risk of functional limitations . Objective The objective of the study is to evaluate the impact of a mobile app ( OA GO ) plus wearable activity monitor/pedometer ( Jawbone UP 24 ) used for 90 days on the mobility of patients with knee OA treated with hylan G-F 20 .  Methods Patients with knee OA aged 30 to 80 years who were eligible to receive hylan G-F 20 and were familiar with smartphone technology were enrolled in this r and omized , multicenter , open-label study . Patients who had a body mass index above 35 kg/m2 were excluded . All patients received a single 6-mL injection of hylan G-F 20 and wore the Jawbone monitor . The patients were then r and omized 1:1 to Jawbone and OA GO ( Group A ; n=107 ) with visible feedback ( unblinded ) or Jawbone only ( Group B ; n=104 ) with no visible feedback ( blinded ) . The primary endpoint was mean change from baseline in steps per day at day 90 between Groups A and B. Results Baseline characteristics were similar between groups . There were significant differences between the increases in least squares ( LS ) mean number of steps per day ( 1199 vs 467 , P=.03 ) and the mean percentage change ( 35.8 % vs 11.5 % , P=.02 ) from baseline in favor of Group A over Group B. There was a greater reduction in pain from baseline during the 6-minute walk test in Group A versus Group B. ( LS mean change : −55.3 vs −33.8 , P=.007 ) . Most patients ( 65.4 % ) and surveys of physicians ( 67.3 % ) reported they would be likely or very likely to use/recommend the devices . Patient Activity Measure-13 scores improved from baseline ( LS mean change for Groups A and B : 5.0 vs 6.9 ) , with no significant differences between groups . The occurrence of adverse events was similar in the 2 groups . Conclusions Use of a novel smartphone app in conjunction with a wearable activity monitor provided additional improvement on mobility parameters such as steps per day and pain with walking in the 6-minute walk test in patients with knee OA who were treated with hylan G-F 20 . Results also highlight the amenability of patients and physicians to using mobile health technology in the treatment of OA and suggest further study is warranted
