Methods: 20 postmenopausal women suffering from pain, who were diagnosed as osteoporosis according to the WHO standard, mean age was 65.2 (range 50-79), were included in this trial. These patients suffered from osteoporotic pain at least 6 months, and the mean course of disease was 5.12 years. 4 patients had osteoporotic fracture. All patients only received the low-frequency pulsed electromagnetic field therapy with ZH-21 osteoporosis treatment system ( Power ≤ 2000VA; Pulsed Frequency:1-100Hz; Magnetic Induction: 0-100Gs with pulsed frequency 1-50Hz, 0-75Gs with pulsed f
