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. Meanwhile, patients in the experimental group were given PEMFs once a day for 30 days.
Results:
The Berg Balance Scale (BBS) scores increased and the timed upand to test (TUG) scores, sway index (forward-backward), rectangle area and sway path decreased in the patients in the experimental group (P < 0.05). In the patients in the control group, only changes in BBS scores and sway path were statistically significant (P < 0.05). The decrease of sway index (forward-backward) in the experimental group was greater than that of the control group (P < 0 01).
Conclusion:
PEMFs can improve the balance ability of patients with post-menopausal osteoporosis.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
