• Abstract: In recent years, sensors from smart consumer devices have shown great diagnostic potential in movement disorders. In this context, data modalities such as electronic questionnaires, hand movement and voice captures have successfully captured biomarkers and allowed discrimination between Parkinson's disease (PD) and healthy controls (HC) or differential diagnosis (DD). However, to the best of our knowledge, a comprehensive evaluation of assessments with a multi-modal smart device system has still been lacking. In a prospective study exploring PD, we used smartwatches and smartphones to collect multi-modal data from 504 participants, including PD patients, DD and HC. This study aims to assess the effect of multi-modal vs. single-modal data on PD vs. HC and PD vs. DD classification, as well as on PD group clustering for subgroup identification. We were able to show that by combining various modalities, classification accuracy improved and further PD clusters were discovered.

  Parkinsons disease (PD) is a neuro-degenerative disorder that affects movement, speech, and coordination. We present PULSAR, a novel method to screen for PD from webcam-recorded videos of finger-tapping. We used an adaptive graph convolutional neural network to dynamically learn the temporal graph specific to the finger-tapping task.

  Parkinson's Disease (PD) is a progressive nervous system disorder that has affected more than 5.8 million people, especially the elderly. Early detection requires neurologists or PD specialists to be involved, which is not accessible to most old people. We introduce the framework of our developed PD early detection system which combines different tasks evaluating both motor and non-motor symptoms.
