Abstract


Two methods which are suitable to monitor the small movements of the patient in a horizontal position on the bed are compared. The methods use sensors based on strain gauge bridges configured to measure the torsion deformation and sensors based on strain gauge bridges configured to measure the bending deformation of two two-arm brackets. Both methods provide information about the patient's physiological movements. The methods were tested and compared in order to decide which methods may be most appropriate in clinical practice. The two methods have never been compared before, and the results can be used in development of the new methods of patient monitoring.
