| Robotic Rehabilitation has illustrated advantages over traditional methods for the past decade. Biological signals, such as electromyography (EMG) signals, are the perfect description of human intention of movements, and they could also be perceptible to robots. Pattern recognition of movements is used to diagnose fatigue and weakness of the patient's muscles. In this study, by evaluating and processing the EMG signal of the wrist, an attempt has been made to diagnose the wrist's muscle fatigue in terms of the patient's EMG signals without the need for wrist movements. For this purpose, by performing laboratory tests of EMG signals for both normal and fatigued wrist subjects, processing and extracting the appropriate features of each signal, wrist movements are divided into four levels in terms of weakness. Sixteen features for each EMG signal have been computed, and SSC (Slope Sign Change), WAMP (Willison Amplitude method), MMAV (Modified Mean Absolute Value), SSI (Simple Square Integral), and MYOP (Mayopulse Percentage Rate) perform better to separate the different levels. The SVM classification method has been implemented on EMG data to classify them into four predetermined levels. The feature selection improves the total accuracy of classification from 89.8% to 93.57% for flexion movements, from 75.9% to 93.2% for extension movements, and from 95.3% to 96.8% for supination-pronation movements. | ||
