A real-time Fuzzy Logic algorithm for freezing of gait management on a smartphone

Abstract

Freezing of gait is considered a clinical problem in Parkinson's disease, due to its episodic nature, heterogeneous manifestation, and drug resistance. Automatic and objective assessment of freezing of gait may help to increase clinical knowledge and to manage its effects on daily living. In this paper, a fuzzy logic algorithm is presented and tested in real-time on a smartphone.
