[Studies on the items for diagnosis of the vibration disease. Part 1. Examination of healthy workers using vibratory tools].

1,215 male workers using bush cleaners in Hokkaido were examined by the method based on the notification of the Labor Standard Bureau. The results obtained from clinically normal 548 workers among them were analysed especially on the finger skin temperature, vibratory sense threshold, maximum grip strength. 1) Data of the vibratory sense threshold, maximum grip strength and endurable grip strength showed normal distributions. Data of the finger skin temperature, however, showed a skewed distribution. 2) In parallel with aging, the vibratory sense threshold increased, in other words, lowered in function, and the maximum grip strength lowered. 3) The endurable grip strength measured by the five-time repetition method decreased along with aging. 4) Values of one-tail limit of the finger skin temperature were calculated in all 548 workers, and those of the vibratory sense threshold, maximum grip strength and endurable grip strength were done in each age group. The values were compared with the already proposed criteria and discussed.
