APPLICATION OF ACOUSTIC SIGNAL PROCESSING METHODS IN DETECTING DIFFERENCES BETWEEN OPEN AND CLOSED KINEMATIC CHAIN MOVEMENT FOR THE KNEE JOINT

Abstract

The paper presents results of preliminary research of analysis of signals recorded for open and closed kinematic chain in one volunteer with chon-dromalacia in both knees. The preliminary research was conducted in order to establish the accuracy of the proposed method and will be used for for-mulating further research areas. The aim of the paper is to show how FFT, recurrence plots and recurrence quantification analysis (RQA) can help in bioacoustic signals analysis.
