It could lead to relaxation or pain management. You would have to work with management of the assistant living facility to determine whether they have space for you, and what your rental charge would be. Many of these people might have a problems with paying for this service.
I live in an active adult community that had a massage therapist, and space in a salon. Most of the people here have moderate incomes, but they did not use the therapist, so the facility was changed to additional space for the salon. Most of those who needed massage therapy had doctor's orders for therapy that Medicare would help pay for, and they went to off-site chiropractor or therapy facilities.
