Abstract:
Objective: To compare moxibustion sensation and infrared thermography by the assessment of heat-sensitization on Guanyuan (CV 4) in patients with primary dysmenorrhea, and to prove the possibility of adopting infrared thermography as an objective demonstration of acupoints heat-sensitization. Methods: Seventy-one patients with primary dysmenorrhea were enrolled to receive moxibustion and infrared to detect the heat-sensitization of Guanyuan (CV 4). The results were then analyzed and compared. Results: The infrared radiation showed a lower temperature when the acupoint Guanyuan (CV 4) was sensitized in patients with primary dysmenorrhea. Compared with moxibustion sensation, its sensitivity rate (real positive rate) was 76.6%, divergence rate (real negative rate) was 70.1%, and the accuracy rate was 74.6%. After giving moxibustion to Guanyuan (CV 4), the infrared radiation area was significantly expanded longitudinally and transversely. Compared with moxibustion test, the sensitivity rate (real positive rate) of infrared test was 78.7%, divergence rate (real negative rate) was 83.3%, and the accuracy rate was 80.3%. Conclusion: To a certain extent, the heat-sensitization of the acupoint Guanyuan (CV 4) in patients with primary dysmenorrhea can be revealed by infrared thermography. The acupoint heat-sensitization phenomena (heat extension or transmission) after giving moxibustion to the heat-sensitized acupoints can also be demonstratedobjectively by infrared thermography, besides experienced subjectively by the receivers.
