[Sensitivity disturbances in patients with neurological pains (author's transl)].

The classical neurological investigation does not provide a satisfactory basis for a clear assessment in most patients with neuralgia. On the other hand, treatment up to now has remained problematic. In this situation measurements of sensitivity may be of benefit: they permit a precise diagnosis and follow-up of the lesions and moreover enable valuable statements allow on the pain perception of the patient. In this paper, the examination procedures for three types of sensitivity are described: touch, temperature and thermic pain. Examples of their application are discussed.
