Accelerometers produce high-resolution physical activity data, but commonly used summary measures often reduce these data to total volume, intensity, or variability and may not retain interpretable temporal structure across the day. Cluster-based summaries may provide a way to characterize daily physical activity profiles while preserving information about when activity occurs.

Early detection and monitoring of wound-related complications after total knee arthroplasty (TKA) are critical to optimize outcomes and preserve implants. Conventional postoperative monitoring relies on in-person assessment and patient-reported symptoms, which may delay recognition. Noncontact imaging acquired in the clinic or at home offers a potential route to earlier and more consistent assessment.

Apolipoprotein E ε4 (APOE-ε4), the strongest genetic risk factor for late-onset Alzheimer disease (AD), is associated with early neuromotor vulnerability that may precede measurable cognitive decline. Because speech integrates fine neuromotor processes, acoustic analysis could offer a sensitive, noninvasive marker of preclinical effects.

Mothers, especially those with low socioeconomic status and minoritized identities, encounter barriers to participating in physical activity (PA), a behavior that improves health outcomes. Moms on the Move (MOMs) is a community-based and theory-informed intervention developed to address the PA barriers endorsed by low-income Black and Hispanic mothers. This intervention offered in-person group PA sessions led by a female fitness instructor and held during children’s sports practices. The MOMs intervention was piloted in 2022 and 2023; the intervention in 2023 was longer (8-weeks, vs 6-weeks) and included goal-setting calls and written materials.

With the rise of digital health, mental health apps (MHapps) have become an increasingly popular tool in the self-management of depression, anxiety, and stress. Star ratings are often used as indicators of app quality to guide selection. However, ratings do not fully capture if the MHapp’s features, usability, or design elements exhibit the heterogeneous real-life user experiences. Instead, examining the patterns of engagement and app usage can highlight whether high ratings reflect diverse user needs.

Traditional Chinese medicine (TCM) has received increasing attention in evidence-based medicine. However, its largely experience-based and practice-oriented nature has slowed modernization and standardization. Advances in AI provide new opportunities for integrating AI with TCM.

The COVID-19 pandemic led to the rapid integration of telemedicine into health care delivery. As a result, the ability to effectively collaborate in interprofessional virtual teams became a necessity, as did the development of educational opportunities designed to equip health care students with these skills. Currently, there is a lack of dedicated tools to assess learners’ ability and readiness to function as a well-coordinated virtual medical team.

This pilot study provides evidence that multimodal online recruitment and engagement are feasible for mixed methods social determinants of health research with sociodemographically diverse Black breast cancer survivors.

Exergames are increasingly used in rehabilitation to simultaneously target physical and cognitive functions. Game scores are commonly used as indicators of performance, yet it remains unclear to what extent they reflect underlying movement and cognitive-control demands. Understanding this relationship is essential for interpreting what exergame performance scores reflect during gameplay.

Behavioral and psychological symptoms of dementia (BPSD) are common among nursing home residents, notably those with Alzheimer disease and related diseases, impacting both themselves and health care professionals. Nonpharmacological interventions, including virtual reality (VR), have shown promise, but evidence from multicenter ecological studies remains limited.

The COVID-19 pandemic has increased the demand for telepsychiatry in neurodevelopmental assessment; however, few studies have examined the interrater reliability of clinician-rated autism scales, such as the Childhood Autism Rating Scale, Second Edition (CARS2), when used remotely. Although the feasibility and validity of telehealth assessments have been explored previously, the consistency between remote and in person CARS2 ratings by different clinicians remains underinvestigated.

Mental Health Online, MindSpot, and THIS WAY UP are 3 Australian Government–funded digital mental health services (DMHSs). These services are free for consumers and deliver a range of (depression and anxiety disorder) psychological assessments and interventions using the internet, with or without clinician support.
