Abstract:
The muscle (M.Brachioradialis) force and electric activity were recorded using Qubit Systems S215 Hand Dynamometer and Qubit Systems S210 EMG Sensor. The surface EMG is recorded from two electrodes (4mm diameter, Ag/AgCl), located parallel to the muscle fibers, the interelectrode distance was 6 cm. Ten patients with history of hemiplegia were compared to 10 control subjects in two group. It was used MATLAB program to analyze experimental data. The componentof 0.2-10Hz was filtered from measured signals to clear artifacts and electromagnetic field. Were done frequency and amplitude analyses of EMG signals from patients comparing to control group. The result shows that these parameters depend on physiological condition.
