[Determination of electrical stimulation pain perception and analysis of the related factors]

The electrical pain perception were determined in healthy Chinese adults and factors were assessed. The anxiety-depression state of one hundred healthy Chinese were evaluated and the general information was recorded. Then electrical pain perception (perception threshold, pain threshold, pain tolerance) were assessed by neuromuscular monitor at the same time. Further study of influence factors such as gender, age, body mass index (BMI), left and right sides, degree of anxiety and depression, etc. were carried out on the pain perception. The results showed that 95% of the reference range of electrical perception threshold, pain threshold, pain tolerance were 4-7mA, 7 26mA and 15-60mA, respectively. The bilateral pain perception in males were significantly higher than that in females. There was no difference of effect between left and right sides. Age was positive related to pain perception, degree of depression was negative related to pain perception. BMI, degree of anxiety did not show association with pain perception. Therefore, gender, age and degree of depression were significantly related to electrical pain perception in healthy Chinese adults.
