Is it dangerous to have chiropractic treatments if you have osteoporosis?

Scientifically, there is little data on chiropractic in people with osteoporosis, said Anthony L. Rosner, a Brookline biochemist who is now director of research and education for the Foundation for Chiropractic Education and Research. There is also little data suggesting that people with osteoporosis are injured by chiropractic treatment, in which the spine is manipulated to restore proper alignment of vertebrae.
