本研究报告了脉冲电磁场（PEMFs）对12只成年雄性Sprague-Dawley大鼠腰椎后路关节融合术影响的组织学数据。手术后，一组6只大鼠通过固定在笼外的一对线圈，每天用pemf刺激18小时。对照组6只，术后不给予任何刺激。在使用pemf刺激的组中，在4周后已经观察到骨痂组织过程的加速，在8周后更是如此：事实上，在4周时观察到新形成的软骨组织与原发性骨（4周）和随后的继发骨（8周后）的早期替换。
This study reports the histological data relative to the effect of pulsed electromagnetic fields (PEMFs) on the evolution of posterior arthrodesis induced in the lumbar vertebrae of 12 adult male Sprague-Dawley rats. After the operation, one group of six rats was stimulated with PEMFs for 18 h per day, by means of a pair of coils fixed to the outside of the cage. A control group of six rats was given no stimulation after surgery. In the groups stimulated with PEMFs an acceleration of the process of bone callus organization was already observed after 4 weeks, and even more so after 8: An early replacement was in fact observed of the newly formed cartilage tissue with primary bone (at 4 weeks) and subsequently with secondary bone (after 8 weeks).
