 Groupings Group 1 MAT placebo LAT: Subjects will receive MAT. The magnetic pellets will have 200 gausspellet magnetic flux densities on average, with a diameter of 1.76 mm Figure 1. The experimental object will be applied to the six selected acupoints as detected by an acupoint finder. The Chinese Standard Ear-Acupoints Chart, which is recognized by the World Health Organization, is used to locate the reflective zones. These zones are as follows: angle of superior conchaprostate, kidney, bladder, ureter, external genitals, and internal genitals Wang, Ceng, Wang, Lin Wang, 1999. To achieve a blinding and placebo effect of the subject, the laser device will be switched to power off mode i.e. deactivated laser for acupoint stimulation before the application of MAT. Subjects will be asked to wear a pair of laser protective goggles to blind them during treatment.
