Abstract
tremorAbstractIntroduction: Smartphone use in biomedical research is becoming more prevalent in differ-ent clinical settings. We performed a pilot study to obtain information on smartphone use bypatients with essential tremor (ET) and healthy controls, with a view to determining whetherperformance of touchscreen tasks is different between these groups and describing touchscreeninteraction factors.Method: A total of 31 patients with ET and 40 sex- and age-matched healthy controls com-pleted a descriptive questionnaire about the use of smartphones. Participants subsequentlyinteracted with an under-development Android application, and performed 4 tests evaluatingtypical touchscreen interaction gestures; each test was performed 5 times.Result: The type of smartphone use and touchscreen interaction were not significantly differ-ent between patients and controls. Age and frequency of smartphone use are key factors intouchscreen interaction.Conclusion: Our results support the use of smartphone touchscreens for research into ET,although further studies are required.
