Low-Level Light Therapy and Cupping Therapy Applied on Skin Tissue

This study investigates the physiological effects of low-level light therapy (LLLT) and cupping therapy (CT) on local skin tissues of the human body. For the experimental light sources of LLLT, light-emitting diodes with wavelengths of 660 nm, 810 nm, and 904 nm and laser diode with a wavelength of 650 nm are adopted. To evaluate the effect of LLLT and CT on the human body, the changes of the skin temperature and muscle elasticity (stiffness) are tracking before and after those treatments. The results show that LLLT, CT, and CT followed by LLLT can relieve muscle tension and activate local muscles. In addition, subjects reported a reduction in local muscle tension after these treatments. Among these three treatments, CT followed by LLLT has the best effect. Among these three treatments, CT followed by LLLT has the best effect. LLLT can also effectively reduce the inflammation of pot mark and relieve post-treatment discomfort.
