El Burgo de Osma (Soria, Spain) offers one of the best preserved medieval structures in Spain. The interior of the building conserves abundant samples of Romanesque art, and the tomb in polychromatic stone of the founder, San Pedro de Osma. We have classified those pieces of art that could represent descriptions of movement disorders. In the main façade of the Cathedral, several statues representing prophets can be seen one of them is clearly different to the rest. This statue represents a man with abnormal cervical posture characterized by right rotation, head tilt and elevation of right shoulder. The tomb includes several statues representing fragments of the life of San Pedro de Osma. Some of these figures show movement disorders. First, a woman with a baby in her arms who has marked head tilt to the left. Second a peasant without hands, perhaps amputated, this man has a head tilt to the right. We suggest that in the latter case ergotism can explain both manifestations: peripheral vascular disease leading to amputation, and cervical dystonia.Finally, a statue of polychromatic wood represents a priest with stooped posture, half open mouth, staring expression and a very notorious anterocollis. The author probably depicted a man with parkinsonism.

SUMMARY The nerve action potential at the elbow and somatosensory evoked potentials (SEPs) at the scalp were recorded over 30 minutes of tourniquet-induced limb ischaemia in 10 diabetic patients and 10 controls. According to the SEP changes, an increased resistance to nerve ischaemia in diabetic patients was observed. The pathways involved in SEP conduction are discussed. etal cortex were recorded every 5 minutes for 30 minutes of induced limb ischaemia and for another 30 minutes after release of the cuff. Two saline soaked felt pad electrodes (11 cm apart) (Medelec EL 210M) and two Ag/AgCl disk electrodes (1 cm of diameter) were used to record NAPs and SEPs, respectively. The recording electrode for SEPs was placed at C,3 (2cm behind C3) (International 10-20 system), referenced to a midfrontal electrode (Fz). A two-channel Medelec MS6 electromyograph was used. The right median nerve was percutaneously stimulated at the wrist with an intensity sufficient to elicit a visible twitch in thenar muscles. Stimuli (square waves of 0-2 ms) were delivered at a rate of 5 Hz. The number of responses averaged was 128. The time analysed was lOOms. Filter setting of 32-3200Hz were used. NAP latency was measured at the first positive peak. Amplitudes were measured peak-to-peak (N19/P22 for the N19 component) and expressed as the percentage value of the pre-ischaemic determination. For statistical evaluation of the results Student's t test and linear correlations were applied.
