  • Title: The average myoelectrical activity of skeletal muscles in healthy and paretic individuals in elementary movements of the limbs.
    Author: Pfeiffer J.
    Journal: Scand J Rehabil Med; 1978; 10(3):121-6. PubMed ID: 705280.
    Abstract:
    The method for evaluation of polyelectromyographic records is described. The method makes it possible to ascertain a deviation degree of myoelectric activity in sick persons with damaged central motoneuron and possibly their return to normal. A set of simple movements was polyelectromyographically examined in 30 healthy persons. These records were transformed into curves of mean value and the standard deviation was enumerated. These patterns were then compared with the pathologic records. The EMG potentials were recorded in the agonist and antagonist of the right and left upper or lower extremity in the motionless state (factor B by Tardieu), simple movement, simple movement against resistance and nociceptive irritation (Babinski phenomenon). The method can be put to good use in the evaluation of therapeutic methods, especially the therapeutic exercise in rehabilitation.
