Applications Of Quantitative Sensory Testing In Breast Pain

Objective:To understand the clinical application characteristics of Quantitative Sensory Testing(QST) and To explore the significance of QST in the study of breast pain. Analysis of pain threshold and sensory system in patients with breast pain, By quantitative determination of breast skin temperature. Materials and methods:Screening of 64 patients with breast pain as the observation group, they were divided into observation group 2 and observation group 3 according to their milk pain score. 20 healthy women were selected as the control group 1. Limit method was chosen for the quantitative determination of 84 female breast skin temperature: cold sense(CS), warm sense(WS), cold pain(CP), heat pain(HP). Results:1.Bilateral breast pain 50 cases accounted for 78.1%. Unilateral breast pain 14 cases accounted for 21.9% and left breast pain in 10 cases accounted for 15.6% and right breast pain in 4 cases accounted for 6.3%.2.The pain range was limited to breast 22 cases accounted for 34.4%. There are 42 cases whose pain involves to other parts accounted for 62.5%. Among them, 40 cases were with axillary pain accounted for 62.5% and 26 cases were with the neck and shoulder parts of discomfort accounted for 40.6% and 3 cases were with back pain accounted for 4.7%.3.There were 4 cases their pain score was bigger than 7 accounted for 6.3%, indicating that the proportion of severe breast pain is small consistenting with relevant research results.4. The average age of the observation group3 was bigger than the group2(P<0.05), indicating that the pain score of older patients tended to be higher.5. Comparing with the control group the sensitivity of WS and HP in observation group2 decreased(P<0.05), and the sensitivity of CS, WS, CP, HP in observation group3 decreased(P<0.05). Indicating that sensory system of breast pain patients was abnormalities but we could,t make sure the cause and location of the lesion.6. The difference of warm detection threshold(WDT) between the 3 groups was significant(P<0.05), indicating that the pain score of the patients with higher WDT tended to be higher. Conclusion:The pain score of older patients tended to be higher. WDT could quantitatively test the degree of breast pain. QST used in the study of breast pain was significant.
