Cranial normality indices in Ugandan infants based on smartphone photogrammetry: key parameters for the study of cranial deformation.

BACKGROUND: Early identification of cranial deformities in infants is essential for timely intervention and preventing long-term complications. In Uganda, particularly in rural areas, access to specialised paediatric healthcare remains limited, making it difficult to diagnose and manage cranial abnormalities early. This study takes a unique approach by using the PhotoMeDAS system. This non-invasive technology allows accurate cranial measurements through QR-based imaging to define normative cranial index ranges for Ugandan infants. By analysing key cranial parameters associated with head shape,

The practice effect of smartphone-derived cognitive processing speed assessments as a proxy of cognitive functioning in multiple sclerosis.

BACKGROUND: In multiple sclerosis (MS), symbol digit modalities test (SDMT) scores are often influenced by practice effects. We evaluated the SDMT practice effect as a proxy of cognitive performance by relating it to disease severity and future performance. METHODS: People with MS (pwMS) and healthy controls (HCs) were evaluated at baseline and five-year follow-up. Practice effects were modeled using two-part piecewise linear regression on daily smartphone SDMT (sSDMT) scores. Cognitive impairment (CI) and preservation (CP) were defined relative to HC baseline sSDMT z-scores (CI: z < -1.67, C…

Assessment of the Sensitivity of a Smartphone App to Assist Patients in the Identification of Stroke and Myocardial Infarction: Cross-Sectional Study.

BACKGROUND: Most people do not recognize symptoms of neurological and cardiac emergencies in a timely manner. This leads to delays in hospital arrival and reduced access to therapies that can open arteries. We created a smartphone app to help patients and families evaluate if symptoms may be high risk for stroke or heart attack (myocardial infarction, MI). The ECHAS (Emergency Call for Heart Attack and Stroke) app guides users to assess their risk through evidence-based questions and a test of weakness in one arm by evaluating finger-tapping on the smartphone. OBJECTIVE: This study is an init…

Smartphone-Based Analysis for Early Detection of Aging Impact on Gait and Stair Negotiation: A Cross-Sectional Study.

Aging is associated with gradual mobility decline, often undetected until it affects daily life. This study investigates the potential of smartphone-based accelerometry to detect early age-related changes in gait and stair performance in middle-aged adults. Eighty-eight healthy participants were divided into four age groups: young (20-35 years), early middle-aged (45-54 years), late middle-aged (55-65 years), and older adults (65-80 years). They completed single-task, cognitive, and physical dual-task gait assessments and stair negotiation tests. While single-task walking did not reveal early …
