Paper Title
A Comparison Study of Detection of Fog Episodes in Parkinson’s Disease Patients

Freezing of Gait (FOG) is an incapacitating gait disorder in Parkinson’s disease (PD) patients that manifests as disruptions in walking with an abrupt and transient nature. Eventhough the patients with earlier stages of PD have been reported experiencing FOG, it becomes more frequent in later stages of PD. It is very exhausting and decreases the quality of life of PD patients. If FOG can be effectively detected before it happens, external cues can be provided to aid the patients to avert the freezing phenomenon. Accelerometer sensors are widely utilized to measure the patient’s movements. EMG sensors and EEG sensors are also utilized to accurately detect the FOG episodes. A comparison of this methods is given in this paper. FOG detection can be used in a broad spectrum of health applications for patient monitoring, to enhance the quality of life for PD patients, and to erode health care cost.
