ABSTRACT:
The invention relates to a method and an apparatus for detecting muscular status. The apparatus includes an electrode (7) for taking up 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 (4) is connected to the signal processing unit.
The analog signals collected by the electrode (7) are converted, after amplification, into binary signals which are analyzed in the signal processing unit (3). This calculates the occurrences of muscle activity below a certain muscle activity level related to an initial muscle activity determined on commencement of the detection. Signals relating to the occurrences of muscle activities below said level are emitted from the signal (4) or stored in a storage device.
