Background: A study was undertaken to evaluate remote monitoring via smartphone sensor-based tests in people with multiple sclerosis (PwMS). This analysis aimed to explore regional neural correlates of digital measures derived from these tests.
Methods: In a 24-week, non-randomized, interventional, feasibility study (NCT02952911), sensor-based tests on the Floodlight Proof-of-Concept app were used to assess cognition (smartphone-based electronic Symbol Digit Modalities Test), upper extremity function (Draw a Shape Test, Pinching Test), and gait and balance (Static Balance Test, Two-Minute Walk Test, U-Turn Test).
Background: In this systematic review we sought to characterize practice effects on traditional in-clinic or digital performance outcome measures commonly used in one of four neurologic disease areas (multiple sclerosis; Huntington's disease; Parkinson's disease; and Alzheimer's disease, mild cognitive impairment and other forms of dementia), describe mitigation strategies to minimize their impact on data interpretation and identify gaps to be addressed in future work.
Methods: Fifty-eight original articles (49 from Embase and an additional 4 from PubMed and 5 from additional sources; cut-off date January 13, 2021) describing practice effects or their mitigation strategies were included.
Results: Practice effects observed in healthy volunteers do not always translate to patients living with neurologic disorders.
DR HAGIS-a fundus image database for the automatic extraction of retinal surface vessels from diabetic patients.
J Med Imaging (Bellingham)
January 2017
A database of retinal fundus images, the DR HAGIS database, is presented. This database consists of 39 high-resolution color fundus images obtained from a diabetic retinopathy screening program in the UK. The NHS screening program uses service providers that employ different fundus and digital cameras.
