An experiment originally done by McElhaney et al. was repeated to obtain additional information about the effects of electrical fields on osteoporosis of disuse. The right femurs of 35 male rats were immobilized in plaster casts. Sixteen rats were treated with transcutaneous electrical fields of 30 Hz and approximately 100 V/cm for periods of 2 or 8 h a day. While the right femurs of the untreated rats were found to be atrophic with respect to the opposite limb, in the treated rats the immobilized femur was made larger than the opposite bone. Longer daily treatments exaggerated this effect. The tumors found in the previous study were not seen in our experiments. Other similarities and differences in the 2 studies are discussed.
重复了最初由麦克尔哈尼等人进行的一项实验，以获取关于电场对废用性骨质疏松症影响的更多信息。35只雄性大鼠的右股骨被固定在石膏模型中。16只大鼠每天接受频率为30赫兹、强度约为100伏/厘米的经皮电场治疗，治疗时间为每天2小时或8小时。未治疗大鼠的右股骨相对于对侧肢体出现萎缩，而在接受治疗的大鼠中，固定的股骨比另一侧的骨头更大。每日治疗时间越长，这种效果越明显。在我们的实验中未发现先前研究中出现的肿瘤。讨论了两项研究中的其他异同点。
