A detailed study of sequential saccadic eye movements for normal- and poor-reading children

This paper presents the results of an in-depth study of parameters characterizing sequenced saccadic eye movements for a group of dyslexic children and a comparative normal control group with ages in the range greater than 8.0 yr. and less than 13.0 yr. No parameters were statistically different for the two groups, which supports the findings of Brown, et al. and contradicts the findings of Pavlidis. Our results indicate that sequenced saccadic eye movements are not diagnostically useful for early detection of dyslexia.     

Effect of stimulus intensity on lingual vibrotactile fusion thresholds

Lingual fusion thresholds for a two-pulse stimulus were obtained at a 15-dB sensation level and a 35-dB sensation level for 15 subjects (18 to 22 yr.). The 35-dB sensation level provided better temporal resolution thresholds as well as less variable responses.     

Acoustically evoked brain stem potential in Wilson disease

By 48 patients with Wilson's disease the brainstem acoustic evoked potentials were stated. There were 35 pathological findings (73%), 13 were normal (27%). The waves, determined by the middle and upper brainstem (Pons and Mesencephalon) showed most of all pathological changes. Those patients with forms of Wilson's disease called Pseudoskelerose and Pseudoparkinson showed the most pathological findings. But one could watch these findings by about 30% of patients in preclinical stage. This method can possibly be used for early detection of disorders of brainstem functions and in the same way it can be used for control of treatment by patients in preclinical stage.     

A patient who had trouble with geography

Aspects of geography are important in relation to the establishment of body ego, since they inevitably supply from the external world the early symbols that represent in the mind the basic elements of infantile experience in regard to body parts, functions, and relationships with primal objects. The accretional inter-twining of all subsequent psychic conflicts can therefore be expressed in symbolic geographic terms. These conflicts center on the developmentally evolving meanings of the mother's body as epitomized in the riddle of the Sphinx. Illustration of the concepts includes a brief clinical report and selected literary and mythological examples.     

Value of mechanographic studies in neuromuscular function diagnosis

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.
