Method & Evidence

AimCan wearable sensors accurately detect motor fluctuations (bradykinesia and freezing of gait) in Parkinson's disease patients within their home environment?
MethodObservational study with sensor data collection
ProcedureInertial measurement units (IMUs) were used to collect data on Parkinson's disease patients. For freezing of gait, a smartphone was placed on the patient's waist. For bradykinesia, a smartphone was placed on the patient's thigh. Data collected from these sensors were analyzed to assess the presence and severity of motor fluctuations.
