title: [A method of measuring centrally determined disturbances of muscle tone (author's transl)].
abstract: A technique is described (myotonography) for recording the centrally determined disturbances of muscle tone, whereby the mechanical and electro-myographic changes in the affected muscle groups are accessible to objective and quantitative study. The efficacity and reliability of the method are given and the clinically distinguishable forms of central disturbances of tonus are shown in typical tracings. These are of particular value for assessing the progress of an illness and the results of treatment. In addition it facilitates the interpretation of the patho-physiological processes. The apparatus is so constructed that in the same way as in a clinical examination, a passive extension and flexion of the elbow joint is reproduced over a range of about 100 degrees. In this way it is possible to record the stretch resistance of the extremities as well as the superficial electromyogram of the flexors and extensors.
