[Conduction in the motor fibers of the ulnar nerve in cut-glass workers].
The authors have estimated the motor conduction velocity of ulnar nerve motor fibres in 39 glass-cutters suspected to neuropathy originating from work performance. The conduction has been checked in two segments; wrist-elbow and below-above elbow (peripheral) and sulcus segments). Twenty-nine workers exhibited reduced conduction; in the sulcus segment--13-fold, in the peripheral segment--4-fold, and in both segments--12-fold. The nerve impairment was greater on the left side, especially in the sulcus segment. After 4 to 24 months another investigation was performed in 22 persons--10 carrying on the work and 12-who had abandoned it. The former group exhibited the impairment, whereas the latter--both improvement and progression. The authors suggest that an appropriate evaluation of the ulnar nerve lesion in glass-cutters but also people representing other professions causing the nerve pressure calls for an investigation of the conduction in the sulcus and peripheral segments.
