Abstract

|
Purpose: At acupoint pressure, the pressing direction of all acupoints is usually vertical. However, it is not clear whether the vertical direction is toward the belly button or the body’s center in the BL52. In this study, the effective direction of acupressure was studied by measuring the pressure pain threshold according to the direction of acupressure in 30 subjects.
Methods: The distance from the subject's GV4 to the left and right BL52 and the distance from GV4 to the navel were measured, and then using the ellipse where the left and right BL52 of GV4 pass through the navel, the angles of the navel direction and the body’s center were calculated in the left and right BL52. The pressure at the time when the subjects felt pain while pressing the BL52 in two directions was used as the acupressure pain threshold. The pain threshold was measured 3 times at 3 minute intervals on the left and right BL52s of the subject.
Results: The acupressure pain threshold measured in the left and right BL52 of the subjects was significantly decreased when pressed toward the trunk center (p < .05). In BL52, it was more sensitive to pressure when the direction of pressure is toward the body’s center.
Conclusions: Acupressure therapy of acupoint is more sensitive to external stimuli than the surrounding. In this study, acupressure directed toward the trunk center is more efficient than toward the belly button in BL52.
