Abstract:

Objective To investigate the effects of hand-transmitted vibration on different traditional Chinese medicine（TCM） constitutions on peripheral nerve damage in male workers，and provide more scientific and personalized diagnosis and treatment plans for clinical practice. Methods A total of 317 male workers with hand-transmitted vibration who underwent occupational health examination in Guangdong Occupational Disease Prevention and Control Institute from 2023 to 2024 were selected as the study subjects by cluster sampling. The traditional Chinese medicine physique classification scale was used to investigate the subjects，and the data were analyzed. Results The average age was （40.63±7.00）years in 317 male patients with hand-transmitted vibration，and the average length of service was （11.81±7.10）years. In all kinds of TCM constitution distribution， the score of peace quality was the highest[（43.1±15.7）points]. The scores of Qi-deficiency，phlegm-dampness and damp-heat in different age groups were statistically significant（all P<0.05），and the scores of Qi-deficiency increased with the increase of age. There were statistically significant differences in the scores of peace quality，Yang deficiency quality，Yin deficiency quality，damp-heat quality，blood stasis quality，Qi stagnation quality and characteristic quality among different age groups（all P<0.05）. The scores of damp-heat quality， blood stasis quality，Qi stagnation quality and characteristic quality increased with the increase of length of service，while the scores of peace quality decreased with the increase of length of service. There were statistically significant differences in the scores of peace quality and Yin-deficiency between normal and damaged peripheral nerve groups（both P<0.05）. Among them，the score of Yin-deficiency was higher than that of normal group，while the score of peace quality was lower than that of normal group. The incidence of peripheral nerve damage was 27.44%. The top three incidence rates of peripheral nerve damage in various traditional Chinese medicine constitution types were Qi deficiency（18.39%），Yang deficiency（16.09%） and Qi stagnation（13.79%）. Multivariate Logistic regression analysis showed that peace quality and damp-heat quality in biased constitution were the high-risk constitution for peripheral nerve damage in male workers exposed to hand-transmitted vibration（both P<0.05）. Conclusion The hand-transmitted vibration work can increase the risk of peripheral nerve damage in male workers with peace quality and damp-heat quality in biased constitution.
