I used to do body control electrotherapy. I have been suffering from severe lumbar muscle strain. After a month of conditioning, my symptoms basically disappeared, and the cost was similar to that of a general meridian physiotherapy shop.

They are only in their thirties and forties, and the investment should not be too big, except for the cost of technicians.

If you open a shop next to the community, after a certain period of time, customers feel that the effect is good and there should be many repeat customers.
