METHOD AND AN APPARATUS IN ELECTROMYOGRAPHY

摘要

The invention relates to a method and an apparatus for detecting muscular status. The apparatus includes electrode means (7) for acquiring analog myoelectric signals, an amplifier (1) which is followed by an A/D converter to which is connected a signal processing unit (3). A signal means (4) is connected to the signal processing unit. The analog signals acquired by the electrode means (7) are converted, after amplification, into binary signals which are frequency-analysed in the signal processing unit (3). This calculates the appearance and/or position of a frequency spectrum in relation to a predetermined initial position on commencement of the detection. Signals relating to the shift of the frequency spectrum in relation to its initial position are emitted from the signal means (4) or stored in a storage device.
