There is no harm, but to control the number, the number of guests operated by the body control electrotherapy technician varies from person to person. If the electrotherapist is older and weaker, he must work according to his own tolerance and not exceed the range of physical load. Second, he should look at his own conditioning projects and set the number of patients every day according to the electricity consumption of different projects. For difficult cases, it is generally recommended that there should be no more than 6 male technicians and 4 female technicians every day. If it is the adjustment of common problems, there will be no more than 8 male technicians and no more than 6 female technicians on average every day. If it is a beauty maintenance project, the quantity can be adjusted according to the technician's personal physique.
