[Diseases of "operating hand" in hypermarket checkout counter workers]

The authors evaluated peripheral neuropathy in 34 female workers of hypermarket checkout counter, via neurologic examination and electric neuromyography. Average length of service in checkout counter was 4 years, maximal one--8 years. All the examinees demonstrated slower peripheral nerve impulse conductivity. 22% of the examinees presented significantly lower nerve impulse conductivity. Right median neuropathy was diagnosed in 47% of the examinees, left one--in 38% of the cases, and ulnar neuropathy--in 24% of the cases. Possibility is that work conditions at major hypermarket checkout counters require improvement.
