I have osteporosis and I have the Baxter. They start you out in the middle settings, but I actually reprogrammed mine to a higher frequency because my mucus is SO sticky - it needs a lot of action to dislodge. I was initially surprised how easily my body tolerated the higher setting. I like to think the percussions are good for osteoporosis - like a vibration plate, the action stimulates your skeleton. After reading countless articles over the years, I do believe that all activity that puts stress on the bones is a good thing. Of course, these are my choices, and I did not check with a medical professional. My worst area on DEXA is -2.6.
