There were 80 participants aged 50 years or older included. Before random assignment to treatment, participants were at least moderate pain during 2 weeks as identified by visual analogue scale (VAS) for more than 4. Bone mineral density (BMD) of all participants was -2.5 or below without diabetes, hyperthyroidism, hypoparathyroidism, liver or kidney function disorder, ovariectomy, rheumatoid arthritis, bone cancer, ever used hormone agent within 6 months before assignment to treatment, ever used steroids more than 3 week before assignment to treatment, Primary outcome measures were the change of VAS scale, Oswestry Disability Index and WHOQOL-BREF Taiwan at week 1 and 12.
