Abstract:
OBJECTIVETo perform quantitative observation on the color change of local skin after cupping, so as to explore objective and quantitative methods for skin response of cupping.
METHODSSeven health subjects were included. By quantitative meridian cupping instrument, cupping methods with four types of pressures were respectively performed on subjects for 5 min.The spectrum of cupping mark before and after the cupping was collected by hyperspectral camera, and the color change was recorded by digital camera.
RESULTSBefore the cupping, the differences of back skin areas were not significant (>0.05), and its average spectrum indicated two peaks at 540-550 nm and 580-590 nm. After cupping with different pressures, spectrum changes of skin were observed. For -0.02 MPa, the most significant reduction was observed at 550 nm (-12.1%,<0.05); for -0.03 MPa, the most significant reduction was observed at 540 nm (-22.1%,<0.05); for -0.04 MPa, the most significant reduction was observed at 610 nm (-26.7%,<0.05); for -0.05 MPa, the most significant reduction was observed at several spectrums (all<0.05).
CONCLUSIONSAfter cupping with different negative pressures, significant changes of spectrum are observed on skin; for different pressures, the spectrums of the most significant changes are different; the hyperspectral camera could be applied to perform quantitative observation on the color change of local skin.
