This in-home diagnostic tool allows doctors to regularly assess the status of their patients with Parkinson’s disease. The laptop-like device leads patients through a series of dexterity, tremor and voice tests. Patients also wear a watch-like accelerometer that collects bodily tremor data, which are easily downloaded by docking the watch to the device. After the data are relayed, doctors can adjust medications and other treatments without requiring patients to leave home. The device also provides researchers with objective scientific data about the progression of the disease versus traditional subjective reporting methods that rely on patient and doctor observation—hopefully speeding the development of new treatments and one day a cure.
