ABSTRACT

Background:

Pediatric oncology patients often experience reduced physical activity (PA) due to treatment-related fatigue, functional limitations, and lack of structured exercise programs. Digital health solutions, including wearable sensors and augmented reality (AR)-based interventions, offer new possibilities for monitoring and improving PA in this population.

Objective:

This scoping review aimed to address existing research gaps by identifying the instruments—both conventional and digital—used to monitor PA in pediatric oncology patients during treatment. In addition, this study examined PA monitoring methods, identified the variables collected, and explored the applicability of digital technologies in facilitating PA engagement among pediatric oncology patients.

Methods:

Following the Joanna Briggs Institute (JBI) methodology, a systematic search was conducted in eight scientific electronic databases. Eligible studies included children aged 7–19 years undergoing cancer treatment or within two years post-treatment. Both objective (accelerometers, wearables) and subjective (questionnaires, self-reports) PA monitoring tools were explored. A narrative synthesis was performed to summarize key findings.

Results:

Twelve studies met the inclusion criteria, utilizing a range of PA monitoring tools. The wearable technologies, such as Actical and Garmin VivoFit® 3, were used in five studies for assessing step counts, gait cycles, and movement intensity. Self-reported measures were identified in 11 studies, including the Activities Scale for Kids© and PedsQL Multidimensional Fatigue Scale proving insights into mobility and fatigue. Despite their feasibility, subjective assessments had limitations due to recall bias and motivation factors. While digital solutions such as gamification and mobile applications demonstrated potential for improving PA adherence, technology application is underused and research on their integration in pediatric oncology remains limited.

Conclusions:

Existing PA monitoring methods provide valuable insights, yet gaps remain in utilizing interactive digital solutions such as AR-based interventions. Future research should focus on integrating digital tools that not only track PA but also actively engage patients, enhance motivation, and facilitate rehabilitation in clinical and home settings.
