Research on Wearable Monitoring System for Freezing of Gait in Parkinson’s Disease

Freezing of gait (FOG) is a common symptom in the late stage of Parkinson’s disease, and it is an important cause of falls in patients. In this study, we have designed a FOG monitoring and management system that can be used in the home environment based on wearable and telemedicine technology. The system uses force-sensitive insoles and inertial sensors to obtain the motion signals of patients, and segments gait cycle and detects FOG in real time in the elastic computing server. The monitoring results can be fed back to the patient to help them restore normal walking ability. Doctors can also know the frequency and degree of FOG attacks in each patient through the system, so as to provide more accurate medical evaluation and drug treatment.
