I think a clinic for low-income or fixed income does not necessarily mean free. Perhaps a minimum income would help defray expenses. Of course would also help fund treatment for those who can not afford it

The concept of community acupuncture clinics seems to be gaining in popularity. These operate with a sliding scale, dependent on income. Patients are treated in one large room, rather than individual treatment rooms. I assume the consultation is done privately, but the larger treatment room allows the practitioner to treat several people at once and keeps overhead low. This type of set up could work for other therapies that don't require patients to disrobe such as shiatsu or acupressure, the difference being that one therapist could only work on one patient at a time. But the overhead of the clinic would still be lower and the sliding scale would allow access by fixed income individuals.
