[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.

[Study on the relationship between body mass index and osteoporosis in males].

There were 482 male patients with non-hyperostosis diagnosed by X-ray among 1207 males who visited West China Hospital because of pain and/or numbness in bone or/and in joints from August 2003 to December 2005; the base-line information in records included age, stature, body weight(calculated BMD, symptoms, co-morbidities, exercise frequency, and smoking. The bone mineral density of lumbar spine was determined and used to judge osteoporosis or non-osteoporosis. Comparison was made on the basic information between osteoporosis group and non-osteoporosis group by t test or chi2 test statistical analysis; the relationship of multiple factors with osteoporosis was analyzed by Logistic Regression.

[On correlation between body mass index and lumbar spine average bone mineral density: a study in male patients with osteopenia and those with osteoporosis].

From among the patients who visited the Dept. of Rehabilitation of West China Hospital for arthalgia in the period from Aug. 2003 to Dec.

[Effect of body mass index on bone mass of lumbar spine of male patients with ostealgia and arthralgia but without osteoporosis].

For the purpose of identifying the effect of body mass index on bone mineral density, an investigation was made in regard to the relationship between body mass index (BMI), bone mineral density (BMD) and bone mineral content (BMC) of lumbar vertebrals of men without osteoporosis. 838 male patients were diagnosed and treated in West China Hospital of Sichuan University because of ostealgia and arthralgia from Aug. 2003 to Dec.

[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.
