Acupuncture in Treating Osteopenia: A Multicenter, Randomized, Controlled Clinical Trial

INTRODUCTION: The aim of this study was to analyze the effectiveness of acupuncture as an early intervention in the treatment of osteoporosis and prevention of osteoporosis. METHODS: This multicenter, randomized, controlled clinical trial was conducted in 226 patients with osteoporosis for 6 months. Participants were randomized to the control group (n = 110) and the acupuncture group (n = 116), both groups received basic treatment with daily calcium carbonate and vitamin D3 tablet (containing calcium 600 mg/tablet) supplementation (n = 116), and the acupuncture group received additional acupuncture treatment. Bone mineral density (BMD), Berg Balance Scale (BBS), bone metabolism indexes, and lower limb muscle strength and balance indexes were tested to evaluate the therapy outcomes of the two groups. RESULTS: After 6 months of treatment, BBS11 (p = 0.046), BBS12 (p = 0.042), and total BBS scores (p = 0) in the acupuncture group were significantly higher than those before treatment; comparing between groups, BBS8 in the acupuncture group was higher than that in the control group after 3 and 6 months, with statistically significant differences (p = 0.036 and 0.0270). After 6 months of treatment, the total BBS score of the acupuncture group was significantly higher than that of the control group, and the difference was statistically significant (p = 0.039). After 6 months of treatment, the BMD of total bone of femoral neck (p = 0.031) and hip joint (p = 0.013) in the acupuncture group was significantly higher than that before treatment, but there was no statistical difference with the control group. The time of five sit-to-stand test (FTSST) was shortened in the acupuncture group, and the difference was statistically significant (p = 0.023), but there was no significant change in the control group (p > 0.05). In addition, the specific sequences of blood phosphorus (p = 0.007), β-collagen (p = 0.009), and N-osteocalcin (p = 0.007) were significantly lower than before treatment after 3 months of acupuncture treatment, and the blood phosphorus level continued to decrease after 6 months of treatment (p = 0.007). In addition, the levels of N-osteocalcin in the acupuncture group were significantly lower than those in the control group after 3 months of treatment (p = 0.008). CONCLUSION: Acupuncture can increase hip bone density, improve bone metabolism, reduce bone turnover rate, and improve body balance and lower limb muscle strength in patients with osteoporosis.
