1. A method of quantifying severity of a subject'"'"'s movement disorder comprising the steps of:

  • providing a device to a subject, the device comprising at least one sensor having a signal corresponding to a subject'"'"'s external body motion associated with a movement disorder;

    measuring the subject'"'"'s external body motion with the at least one sensor while the subject performs at least one movement disorder test corresponding to at least one movement disorder symptom;

    transmitting a signal from the at least one sensor to a processor; and

    calculating substantially in real time with the processor a symptom quantification measure based at least in part on the signal from the at least one sensor;

    wherein the device has a real-time average intraclass correlation (ICC) of at least about 0.60, and the device also has a real-time average minimum detectable change (MDC) that represents a change of about 25% or less of the total scale of the particular test.
