Classification of knee-joint vibroarthrographic signals using time-domain and time-frequency domain features and least-squares support vector machine Abstract: Analysis of knee-joint vibration sounds, also known as vibroarthrographic VAG signals, could lead to a noninvasive clinical tool for early detection of knee-joint pathology.
In this paper, we employed the wavelet matching pursuit MP decomposition and signal variability for time-frequency domain and time-domain analysis of VAG signals. The number of wavelet MP atoms and the number of significant turns detected with the fixed threshold from signal variability analysis were extracted as prominent features for the classification over the data set of 89 VAG signals.
Compared with the Fisher linear discriminant analysis, the nonlinear least-squares support vector machine LS-SVM is able to achieve higher overall accuracy of Article :.

Application of acoustic signal processing methods in detecting differences between open and closed kinematic chain movement for the knee joint. The paper presents results of preliminary research of analysis of signals recorded for open and closed kinematic chain in one volunteer with chondromalacia in both knees.
The preliminary research was conducted in order to establish the accuracy of the proposed method and will be used for formulating 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. Opis fizyczny.

Referring to Table 1 and Figure 5 , the superiority of the DWF-based ensemble in the diagnostic performance was prominent. To overcome such a drawback, the lowpass Butterworth filter and the fixed threshold method were introduced in the present study. The portal can access those files and use them to remember the user's data, such as their chosen settings screen view, interface language, etc. Auscultation of the knee joint using a stethoscope was also performed, and a qualitative description of the sound intensity and type was recorded.
