Abstract:
In controls and patients with different syndromes (spastic/flaccid paresis, low back pain syndrome), the myoelectrical activation patterns of complex muscles (M. biceps brachii, M. quadriceps femoris, M. masseter) or synergistic/antagonistic muscle groups in the back region during isometric muscle contractions and defined movements were determined by monopolar 16 (32) channel surface EMG recordings. On the basis of these recordings, maps of myoelectrical activation ("EMG-maps") were calculated. This method permits a detailed quantitative-topographic EMG analysis including the characterization of therapy effects.
