Analysis of Moisture, Elasticity and EMG Change on Meridian Acupoints by Cupping(Negative Pressure) Stimulation

Abstract

Cupping therapy has been used to extensive diseases. However, the research was yet to meridian and acupoint's change of state caused by Cupping. This study was considered a human-ripple effect by the anlaysis of meridian & acupoint's change of state. We developed the system which is keeps 30㎪ Negative-pressure and stimulated on the Left Lung Meridian(LU) a halfway point between LU4 and LU5. We checked moisture and elasticity change on left/right acupoints & non-acupoints, then measured EMG Signal. We observed that moisture had little change(12.49%) and the better part of the elasticity on both sides had identified the change(64.42%). The number of the provoked acupoiunt elasticity change was more than non-acupoint. Also, elasticity change of Right side was more than Left side. We confirmed that RMS and Median Power change patterns were lower in proportional to the elastin change, but there was no significance about Median Frequency. Therefore inducing the change of elasticity and EMG signal on meridian-acupoints. Therefore, We checked the human-ripple effect Negative-pressure by the Cupping therapy.

Pressure Levels in Cupping Therapy: A Systemic Review

“…The constant negative pressure in the studies by Im and Moon [5], Park and Lee [7], Kweon et al [9], and Lee et al [10] was 60 mmHg. The constant negative pressure was 225 mmHg in the study by Kim et al [15], 240 mmHg in the study by Shin et al [6], and 400 mmHg in the study by Oh and Kim [8]. In comparison, the constant negative pressure in the studies by Shin [4], Ryu et al [11], Kim et al [16], Kim et al [18], and Kim et al [20] was 600 mmHg (Table 3).…”
