Classification of movement states in Parkinson's disease using a wearable ambulatory monitor.

Author information

Brigham and Women's Hospital, Boston, MA, USA.


For Parkinson's patients to function at their best, the clinicians who care for them must be able to manage and offset the fluctuations in movement that occur throughout the day. Symptoms of Parkinsonism such as bradykinesia, hypokinesia and akinesia and medication-related side effects such as dyskinesia need to be reported to the clinician in a manner that accurately conveys the timing and severity of symptoms. The clinician can then tightly adjust and titrate the timing and dosing of medication, allowing the patient to function at his or her best. Patient history and patient self reporting diaries are currently used for this purpose, but they have problems with compliance, completeness and reliability. A monitor that could be worn by the patient while he or she is at home and could issue to the clinician a report of how the patient has been moving over the course of the day would be a great help to clinicians. Wearable devices have been studied for the measurement of movement in Parkinson's patients, but none have been designed in a manner that would be useful for the titration of medications 1, 2, 3.
