Abstract
Background and objective. Aromatase inhibitor therapy for postmenopausal women with breast cancer is associated with a decrease in bone mineral density (BMD). Both Pulsed electromagnetic fields (PEMFs) and treadmill walking exercises have a positive effect on bone osteoporosis. So, this study aimed to evaluate the effect of PEMFs and treadmill weight bearing exercises on the BMD of the lumbar spine in women with osteoporosis secondary to adjuvant hormonal treatment with aromatase inhibitor.
Methods. A total of 45 female breast cancer patients with osteoporosis secondary to adjuvant aromatase inhibitor were randomly assigned into three equal groups. The control group received only pharmacological treatment (Bisphosphonates, Calcium and Vitamin D). In the other 2 groups, the same drug therapy was consolidated by a program of treadmill weight bearing exercises (treadmill exercise group; 30 min/session, 3 sessions/week), and PEMFs (PEMFs group; 30 min/session, 3 sessions/week). The BMD of the spinal vertebrae was assessed before and after 3 months of intervention by using the Dual energy X-rays (DEXA).
Results, The post value of the PEMFs group was significantly higher than those of the treadmill exercise group and the control group (p = 0.002, 0.001 respectively), and the post value of the treadmill exercise group was significantly higher than that of the control group (p= 0.001), The post values of the three groups were higher than pre values (p = 0.001).
Conclusion. Both treadmill weight bearing exercises and PEMFs were effective in improving the BMD. Moreover, the BMD response to PEMFs was better than treadmill weight bearing exercise.
