Tummy Time Tracking: Concurrent-Validity of Wearable Sensors in Home Settings for Term and Preterm Infants.
Purpose: To assess the concurrent validity of 2 wearable sensors, GENEActiv (GA) and MonBaby (MB), for tracking tummy time in full-term and preterm infants at home.
Methods: Nineteen full-term infants and 13 infants born preterm, aged 3 to 6 months, wore GA and MB sensors during caregivervideo-recorded active play at home over 3 days. Prone (tummy time) durations detected by each sensor were compared to video for validation.
Results: Both GA and MB sensors demonstrated excellent (κ = 0.86) and substantial (κ = 0.78) second-by-second agreement with video, respectively, for tracking tummy time. For cumulative tummy time, the GA showed higher accuracy with video (GA =60 minutes, video =58 minutes, difference =2 minutes) compared to MB (MB =43 minutes, video =47 minutes, difference =4 minutes). No differences in accuracy were found between the 2 sensors.
Conclusion: Wearable sensors can accurately track tummy time at home and can support adherence to movement guidelines in infants. Establishing caregiver feasibility is crucial for broader use.
期刊介绍：
Pediatric Physical Therapy is an indexed international journal, that publishes peer reviewed research related to the practice of physical therapy for children with movement disorders. The editorial board is comprised of an international panel of researchers and clinical scholars that oversees a rigorous peer review process. The journal serves as the official journal for the pediatric physical therapy professional organizations in the Netherlands, Switzerland, New Zealand, Canada, and the United States. The journal includes articles that support evidenced based practice of physical therapy for children with neuromuscular, musculoskeletal, cardiorespiratory and developmental conditions that lead to disorders of movement, and research reports that contribute to the foundational sciences of pediatric physical therapy, ranging from biomechanics and pediatric exercise science to neurodevelopmental science. To these ends the journal publishes original research articles, systematic reviews directed to specific clinical questions that further the science of physical therapy, clinical guidelines and case reports that describe unusual conditions or cutting edge interventions with sound rationale. The journal adheres to the ethical standards of theInternational Committee of Medical Journal Editors.
