Article Synopsis
  • - The study introduces a new method for non-contact respiratory rate (RR) estimation in infants, which is important given their sensitive skin, particularly in a neonatal intensive care unit (NICU) setting.
  • - Researchers used an advanced technique called Eulerian video magnification to enhance video footage and developed a unique way to set peak prominence thresholds to handle challenges like low light and babies being swaddled.
  • - The results show that the new algorithm reliably estimates RR, achieving high agreement with visual counts compared to traditional methods, indicating its effectiveness even in challenging NICU conditions.

Background: People with Achilles tendinopathy (AT) experience persistent pain that can limit engagement with daily occupations and negatively impact mental health. Current therapeutic exercise approaches vary in success, with many people experiencing reinjury, leading to a cycle of chronic tendinopathy often lasting years. High-magnitude precision loading may help people exit this feedback cycle, but applying these principles clinically is challenging.

Article Synopsis
  • The study assessed the feasibility of using co-designed in-home data collection methods with families of youth with developmental disabilities, focusing on youth aged 14-18 with conditions like autism, cerebral palsy, and chronic pain.
  • Over 14 days, participants engaged in data collection by wearing accelerometers, completing questionnaires, and sampling saliva, with results showing decent engagement but some challenges in adherence to the saliva sampling.
  • Families expressed high satisfaction and interest in participating again, highlighting the importance of the research's relevance and the necessity for personalized approaches based on their feedback.

Background: Children with severe neurologic impairment (SNI) regularly require major surgery to manage their underlying conditions. Anecdotal evidence suggests that children with SNI experience unexpected and persistent postoperative functional changes long after the postoperative recovery period; however, evidence from the perspective of caregivers is limited. The purpose of the study was to explore the functional postoperative recovery process for children with SNI.

This paper explores automated face and facial landmark detection of neonates, which is an important first step in many video-based neonatal health applications, such as vital sign estimation, pain assessment, sleep-wake classification, and jaundice detection. Utilising three publicly available datasets of neonates in the clinical environment, 366 images (258 subjects) and 89 (66 subjects) were annotated for training and testing, respectively. Transfer learning was applied to two YOLO-based models, with input training images augmented with random horizontal flipping, photo-metric colour distortion, translation and scaling during each training epoch.
