Thanks for your reply. I was diagnosed with osteoporosis at 64 despite always having an active lifestyle- mostly hiking and trail running on hills in my 50s. Unfortunately, I recently underwent pelvic radiation for cancer, which puts me at increased risk for increased bone mineral loss and insufficiency fractures. I have added strength training with osteoporosis safety precautions and some yoga postures, but I have left hip arthritis and arthritis in both thumbs/wrists, so I am looking at all my options. I was hoping someone manufactures a device that delivers LIV for $1000 or less. I haven't been able to find one, only whole-body vibration plates, which I don't want.
