Pulsed electromagnetic fields for postmenopausal osteoporosis and concomitant lumbar osteoarthritis in southwest China using proximal femur bone mineral density as the primary endpoint: study protocol for a randomized controlled trial.

Background: Osteoporosis (OP) and osteoarthritis (OA) are prevalent skeletal disorders among postmenopausal women. Coexistence is common especially that of postmenopausal osteoporosis (PMO) and lumbar OA. An hypothesis has been raised that OP and OA might share the same pathogenic mechanism, and pulsed electromagnetic fields (PEMFs) were reported to have anti-osteoporosis and anti-osteoarthritis properties, but this suggestion was based primarily on biomarker data.

[The effect of low-frequency pulsed electromagnetic fields on balance ability of patients with post-menopausal osteoporosis].

Objective: To assess the effect of pulsed electromagnetic fields (PEMFs)on balance ability of postmenopausal women with osteoporosis.

Methods: 43 eligible patients were randomly divided into experimental (n = 24) and control (n = 19) groups. Patients in both groups received conventional drug therapy.

Pulsed electromagnetic fields on postmenopausal osteoporosis in Southwest China: a randomized, active-controlled clinical trial.

A randomized, active-controlled clinical trial was conducted to examine the effect of pulsed electromagnetic fields (PEMFs) on women with postmenopausal osteoporosis (PMO) in southwest China. Forty-four participants were randomly assigned to receive alendronate or one course of PEMFs treatment. The primary endpoint was the mean percentage change in bone mineral density of the lumbar spine (BMDL), and secondary endpoints were the mean percentage changes in left proximal femur bone mineral density (BMDF), serum 25OH vitamin D3 (25(OH)D) concentrations, total lower-extremity manual muscle test (LE MMT) score, and Berg Balance Scale (BBS) score.

[Association of physical activities and bone mass density of lumbar spines in men].

Objective: To determine the association of physical activities and bone mineral density of lumbar vertebrae in men.

Methods: A total of 1169 men who sought medical attentions in the West China Hospital of Sichuan University from August, 2003 to December, 2005 because of ostealgia and arthralgia were given a dual-energy X-ray absorptiometry for the L2-L4 bone mineral density. The height, weight, smoking history, and diseases (eg.

Correlation between obesity and female hyperostosis.

Background: Hyperostosis is a common pathological change among people more than 50 years old; it is connected with many risk factors, which are all indefinite. The aim of this study was to prospectively investigate the correlation between obesity and female hyperostosis.

Methods: Totally 4326 females were included in this study and their basic information including their age, stature, body weight, course of disease, symptoms, medical complications, frequency of exercise and smoking, and X-ray and bone mineral density (BMD) examination results, was carefully collected for a statistical analysis.
