Using of inertial measurement unit (imu) in movement analysis in persons with parkinson’s disease

Abstract

Parkinson’s disease (PD) is a second commonest neurodegenerative disorder, followed by the presence of motor symptoms that affect the functioning of a person in the community Technology development and implementation of various diagnostic and assessment procedures can improve the rehabilitation process of this population. IMU sensors have the potential to identify and provide valuable information about motor performances and behavior, as well as the quality of movements. The aim of this paper is to present the possibilities of using Inertial Measurement Units sensors in movement analysis in persons with Parkinson’s disease. Analyzed papers were selected by researching electronic databases: PubMed/MEDLINE, Science Direct, Scindeks, and Google Scholar and published between 2014 and 2020. The analyzed researches have shown that the IMU can be used in the evaluation of motion range and amplitude, repetitive finger taping parameters, characteristics of movements and activities important for everyday living, gait characteristics and parameters, as well as PD related symptoms, such as bradykinesia, tremor, festination, freezing of gait. Sensors, consisted in IMU, also can befused together to provide a 3D picture ofhuman motion.
