BACKGROUND: Smart wearables such as the Fitbit wristband provide the opportunity to monitor patients more comprehensively, to track patients in a fashion that more closely follows the contours of their lives, and to derive a more complete dataset that enables precision medicine. However, the utility and efficacy of using wearable devices to monitor adolescent patients' asthma outcomes have not been established. OBJECTIVE: The objective of this study was to explore the association between self‑reported sleep data, Fitbit sleep and physical activity data, and pediatric asthma impact (PAI)...

Fitness bands are widely available and assist with tracking the number of steps taken. However, for older people with slow gaits, shorter step widths and/or use of ambulatory devices, the accuracy of fitness bands for step counting has not been well studied. Using four commercially available fitness bands (Garmin Vivofit2™, Fitbit Flex™, Up3™ and Microsoft Band™), we studied 30 older people with varying ambulatory abilities. We videotaped participants walking and compared the videotaped step count with the fitness band counts...

OBJECTIVE: Most persons who undergo total knee replacement (TKR) do not increase their physical activity following surgery. We assessed whether financial incentives and health coaching would improve physical activity in persons undergoing TKR. METHODS: We designed a factorial randomized controlled trial among persons undergoing TKR for osteoarthritis. Subjects underwent normal perioperative procedures, including post-operative physical therapy, and were assigned to one of four arms: attention control, telephonic health coaching (THC), financial incentives (FI), or THC+FI...

INTRODUCTION: Chronic breathlessness is highly prevalent and distressing to patients and families. No medication is registered for its symptomatic reduction. The strongest evidence is for regular, low-dose, extended- release (ER) oral morphine. A recent large phase III study suggests the subgroup most likely to benefit have chronic obstructive pulmonary disease (COPD) and modified Medical Research Council breathlessness scores of 3 or 4. This protocol is for an adequately powered, parallel-arm, placebo-controlled, multisite, factorial, block-randomised study evaluating regular ER morphine for chronic breathlessness in people with COPD...

INTRODUCTION: Obesity and physical inactivity are major societal challenges and significant contributors to the global burden of disease and healthcare costs. Information and communication technologies are increasingly being used in interventions to promote behaviour change in diet and physical activity. In particular, social networking platforms seem promising for the delivery of weight control interventions.We intend to pilot test an intervention involving the use of a social networking mobile application and tracking devices (Fitbit Flex 2 and Fitbit Aria scale) to promote the social comparison of weight and physical activity, in order to evaluate whether mechanisms of social influence lead to changes in those outcomes over the course of the study...

INTRODUCTION: Consumer-based physical activity monitors (PAMs) are becoming increasingly popular, with multiple global organisations recommending physical activity levels that equate to 10,000 steps per day for optimal health. We therefore aimed to compare the step count of five PAMs to a visual step count to identify the most accurate monitors at varying gait speeds, along with the optimal anatomical placement site. METHODS: Participants completed 3min on a treadmill for five speeds (5...

BACKGROUND: Only one in five American meets the physical activity recommendations of the Department of Health and Human Services. The proliferation of wearable devices and smartphones for physical activity tracking has led to an increasing number of interventions designed to facilitate regular physical activity, in particular to address the obesity epidemic, but also for cardiovascular disease patients, cancer survivors, and older adults. However, the inconsistent findings pertaining to the accuracy of wearable devices for step counting needs to be addressed, as well as factors known to affect gait (and thus potentially impact accuracy) such as age, body mass index (BMI), or leading arm...

BACKGROUND: Physical activity (PA) may be important for preventing chronic diseases for adolescent and young adult (AYA) childhood cancer survivors. Randomized controlled trials (RCTs) of PA interventions for AYA survivors are sparse, but necessary to determine effective programs for increasing PA among this population. Thus, we conducted a pilot RCT, testing the feasibility of a mobile health (mHealth) intervention to promote PA among AYA survivors. PROCEDURE: We recruited 14- to 18-year-olds who were ≥1-year post cancer therapy from Seattle Children's Hospital...

Consumer-level activity monitors, such as Fitbit and Misfit devices, are a popular and low-cost means of measuring physical activity. This study aims to compare the accuracy of step counts from two consumer-level activity monitors against two reference devices in healthy, community dwelling older adults in free-living conditions. Twenty-five older adults (aged 65-84) simultaneously wore 5 devices (e.g. Misfit Shine and Fitbit Charge HR) over 7 consecutive days. All consumer-level activity monitors positively correlated with reference devices (p<0...

Our purpose in this study was to document the criterion validity of the Fitbit Zip for measuring steps taken by youth with visual impairments (VI). A secondary purpose was to determine whether walking pace, mounting position, or relative position to the user's mobility device impacted the criterion validity of the device. Fourteen adolescent-aged individuals (Mage = 15.4; 13 male and 1 female) with VI participated in this study. Participants wore four Fitbit Zips at different mounting positions and completed two, 2-min walking trials while the lead investigator hand tallied steps...
