[Multiple local involvement of peripheral nerves in workers suffering from occupational hands disorders].

Stimulation and needle electromyography studies covered 102 patients with occupational hands disorders. 87% of the examinees showed tunnel syndromes signs: 44% of those had one tunnel syndrome, 36% - two synromes, and 7% - multiple ones. The results failed to demonstrate reliable difference in tunnel syndrome frequency for vibration exposure and functional hands overstrain. Sensitivity thresholds in vibration disease were increased in 86.7% of the examinees and in 61.5% of those with functional hands overstrain. Peripheral nerve disorders in residual defects with occupational hands diseases are persistent due to compression within physiologic tunnels.
