title: [Value of mechanographic studies in neuromuscular function diagnosis].
abstract: Mechanographic examinations have hitherto played only a minor role in general clinical neuromuscular functional diagnostics. The purpose of this contribution is, therefore, to present an appropriate recording apparatus (W. Zett , 1969), to report on the values that can be considered normal and to outline the diagnostic value of the method using clinical applications as examples. Special value is attached to simultaneous recording of the EMG and the mechanograph because this method permits differentiated conclusions to be drawn regarding disturbances in muscular activity, the electromechanical coupling and the actual process of contraction. The method is also important for pharmacological investigations and should be used principally in connection with musclepathology for objectifying the effects of medication.
