ABSTRACT:
A method and apparatus for detecting muscular status in which electrodes are connected to the body muscles being investigated for producing analog myoelectric signals which are amplified in an amplifier and fed to an A/D converter connected to a signal processing unit. A signal device is connected to the signal processing unit. The analog signals from the electrodes are converted, after amplification, into binary signals which are frequency-analyzed in the signal processing unit by comparing the appearance and/or position of a frequency spectrum in relation to a predetermined initial position at commencement of the detection. Signals relating to the shift of the frequency spectrum in relation to its initial position are emitted by the signal device or stored in a storage device.
