Trial Summary

Do I have to stop taking my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the Smart Walk App treatment for increasing physical activity?

Research shows that using smartphone apps with accelerometers, like the Smart Walk App, can help increase physical activity in hospitalized patients. Studies found that similar apps led to more time spent standing and walking, and improved recovery after surgery. ^{1 2 3 4 5}

Is the Smart Walk App generally safe for humans?

Research on physical activity interventions, like those involving apps, shows that while minor injuries can occur, no serious adverse events have been reported. It's important to start slowly and gradually increase activity levels to minimize risks. ^{6 7 8 9 10}

How is the Smart Walk App treatment different from other treatments for increasing physical activity?

The Smart Walk App is unique because it uses smartphone technology and social networking to motivate users to walk more, offering a persuasive and interactive approach compared to traditional methods like pedometers or step counters. ^{11 12 13 14 15}

Findings from Research

A goal-directed movement intervention using a movement sensor significantly increased the daily physical activity of hospitalized patients from an average of 38 minutes to 50 minutes, indicating its effectiveness in promoting movement during hospitalization.

Patients reported a decrease in perceived difficulty to move, suggesting that the intervention not only increased activity levels but also improved patients' confidence in their ability to move.

A study involving 78 hospitalized patients showed that using the Hospital Fit app alongside usual physiotherapy led to a trend of increased physical activity, particularly in standing and walking, although the results were not statistically significant.

Patients who used the app for longer periods experienced greater increases in physical activity, suggesting that the app may be beneficial for functionally independent patients in promoting movement during hospitalization.

Interventions using activity trackers during and after inpatient care can significantly increase physical activity levels in patients, with a small positive effect size (SMD = 0.34) observed in 13 studies involving 1435 patients.

However, these increases in physical activity did not lead to significant improvements in physical functioning, indicating that while activity trackers can motivate patients to move more, they may not directly enhance overall physical capabilities.

Interventions using wearable activity trackers during hospitalization significantly increased overall physical activity levels and reduced sedentary behavior among 1911 participants across various medical conditions, showing a standardized mean difference of 0.35 for activity and a reduction of 35.46 minutes per day in sedentary time.

Patients using these trackers also experienced improvements in physical function, with a standardized mean difference of 0.27, indicating that these devices can enhance recovery during hospital stays, although they did not significantly affect pain, mental health, length of stay, or readmission rates.

The Hospital Fit smartphone app significantly increased the time hospitalized patients spent standing and walking by an average of 28.43 minutes on postoperative day one, compared to standard physiotherapy alone.

Patients using Hospital Fit had 3.08 times higher odds of achieving functional recovery on postoperative day one, indicating that digital health tools can effectively enhance physical activity and recovery in hospitalized patients.

In a 6-month pilot study involving 55 healthy young adults, participants in the overweight-obese group experienced a short-term decrease in BMI but did not maintain this change, indicating challenges in sustaining weight loss and negative feelings associated with social comparison on the app.

Conversely, participants in the underweight-normal BMI group actively engaged with the app's self-monitoring and social features, leading to a significant increase in their daily step count, highlighting the need for personalized interventions to cater to different user experiences and motivations.

In a review of over 5,500 participants from 11 physical activity interventions, no serious study-related adverse events were reported, indicating a high level of safety in these exercise programs.

While minor musculoskeletal injuries were noted, the studies emphasized a 'start low and go slow' approach, suggesting that moderate-intensity physical activity is safe and effective for sedentary, chronically ill, or older populations.

A systematic evaluation of seven DASH diet apps revealed that only two apps, NOOM and DASH To TEN, met both quality and data security standards, making them suitable for supporting self-management of the DASH diet.

While three apps scored high in quality across various domains, most apps exhibited significant shortcomings in quality and data privacy, highlighting the need for better app development in this area.

A study evaluated 4 DASH (Dietary Approaches to Stop Hypertension) apps, finding that only one paid app scored high in quality, while the free apps generally had lower quality ratings.

The research highlights the need for better development of free DASH apps, as the current options may not effectively support users in managing hypertension through diet.

This systematic review aims to identify the barriers and facilitators that adults face when using mobile apps and wearable technology to monitor their physical activity and sedentary behaviors, which could help improve health outcomes.

The review will analyze qualitative studies published since 2012, providing insights that can guide the development and implementation of these technologies for better user engagement and effectiveness.

A systematic review of 27 studies found that health and fitness apps can lead to significant improvements in diet, physical activity, and sedentary behavior, particularly in adults, with 17 out of 23 adult-targeted studies showing positive health outcomes.

Multi-component interventions that include apps were more effective than stand-alone app interventions, suggesting that combining app features with other strategies may enhance user engagement and health benefits.

A new mHealth application designed to promote physical activity was developed based on seven key characteristics identified from a review of existing technologies, and it was successfully deployed over a 4-week period with 14 participants.

Participants reported high usability scores (average 4.52 out of 5) and used the app for an impressive total of 119,380 minutes, averaging about 7.57 hours per day, indicating strong engagement and satisfaction with the application.

A systematic review of 35 studies involving 7454 participants found that mobile app and tracker interventions led to a small-to-moderate increase in physical activity, equating to an average of 1850 additional steps per day.

Interventions that included text messaging and personalized features were particularly effective, suggesting that these elements enhance user engagement and activity levels.

The Digi-Walker step counter effectively measures physical activity, with a study of 31 adults showing that step counts vary significantly based on pace and individual characteristics like height and body fatness.

Participants averaged 11,603 steps per day when including vigorous activity, suggesting that while pedometers are useful for tracking steps, establishing universal step count guidelines is challenging due to individual variability in activity patterns.

The iPedometer application for iPhone was found to be inaccurate in counting steps compared to a reliable StepWatch 3 Step Activity Monitor and a tally counter, especially at various walking speeds.

Out of all tested conditions, the iPedometer only showed a positive correlation in step counting when used on the arm at the slowest speed, indicating it is not a valid tool for monitoring physical activity during treadmill walking.
