[Spastic movement disorders: non-medicamentous therapies based on neurophysiologic principles].

Lesions of the upper motor neurons cause a spastic syndrome and a central paresis. The consequence of these "plus" and "minus" symptoms on locomotor function is a spastic movement disorder. Strategies of physical therapy for the spastic movement disorders are discussed in relation to research findings in neurophysiology and muscle physiology. The main therapeutic technics are physiotherapy, functional electrical stimulation (FES) and biofeedback training (BFB). Various methodological problems which arise in carrying out and evaluating therapeutic studies are described. Valid prognostic criteria are essential in order to achieve an optimal use of the different therapeutic procedures. This review underlines the need for further research, since some important questions remain open.
