Effectiveness of Pulsed Electromagnetic Fields on Bone Healing: A Systematic Review and Meta‐Analysis of Randomized Controlled Trials

“…In the outcome of pain, when we omitted the trial performed by Mohajerani et al [2019], I 2 changed from 60% to 0% but the merger effect size remains unchanged, suggesting that the research by Mohajerani et al [2019] is the main source of heterogeneity. Omitting any trial did not change the results of meta‐analysis, suggesting that the result is robust and PEMF intervention can significantly relieve pain.…”

“…Three trials reported BMD. Mohajerani et al [2019] reported PEMF did not increase BMD after 2 weeks of intervention, but increased BMD at 28 days of follow‐up. Yang and Yang [2005] reported that BMD of collum femoris was higher than that of control after intervention of 1 month ( P < 0.01), 2 months ( P < 0.01), and 3 months ( P < 0.01), and BMD of lumbar vertebra was also higher than that of control after intervention of 1 month ( P < 0.05), 2 months ( P < 0.05), and 3 months ( P < 0.05).…”

Modern Physical Methods of Stimulating the Bone Tissue Healing Processes

“…Під впливом постійного та змінного імпульсного магнітного поля відзначається посилення метаболічних процесів в ділянці кісткового регенерату, в більш ранні терміни з'являються фібро-та остеобласти в ділянці регенерації, процес утворення кісткової речовини проходить інтенсивніше та у більш ранні терміни [45][46][47][48]. У низці досліджень на тваринах доведено, що магнітотерапії властива седативна, гіпотензивна, протизапальна, протинабрякова, знеболююча і трофіко-регенеративна дія [4,49,50]. На противагу, Rosso F. et al, 2015 [51] не виявили статистично достовірних доказів ефективності магнітотерапії у порівнянні з ЕУХТ.…”

“…У царині щелепно-лицевої хірургії серед потенційних показань до застосування магнітотерапії виокремлюють: захворювання пародонту; гострий артрит СНЩС; переломи нижньої щелепи; післяопераційні рани та травми [44,49]. Проте, відкритим залишається питання щодо використання магнітотерапії за наявності металевих конструкцій у порожнині рота [44,39].…”

Effects of extremely low-frequency electromagnetic field exposure on the skeletal muscle functions in rats

“…It is not yet entirely clear, however, whether the effects of ELF-EMFs on the human body is beneficial or harmful. It was found that ELF-EMFs have significant effects on cells and tissues and their functions in the living organisms, such as a marked change in the synaptic plasticity generated in synapses of the dentate gyrus (Komaki et al, 2014); persistent changes in neuronal activity after prolonged exposure to ELF-EMFs (Komaki et al, 2014); dramatic effects from behaviour to physiology and protein expression (Wyszkowska et al, 2016); important alterations of glucose and lipid metabolisms (Hashish et al, 2008); deleterious effect on ultra structure of prostate gland in rat (Khaki et al, 2008); the occurrence of oxidative stress-based nervous system pathologies associated with ageing (Falone et al, 2008); regulation of calcium-related activities in cardiomyocytes (Wei et al, 2015); absence of evidence of persisting unrepaired nuclear DNA single-strand breaks in distinct types of cells in the brain, kidney and liver of adult mice after continuous 8-week 50 Hz magnetic field (MF) exposure with flux density of 0.1 or 1.0 mT (Korr et al, 2014); changes in the synthesis and release of oestradiol-17β (E2) in uterine tissues (Koziorowska et al, 2018); the treatment of cerebral ischaemia by reduction neuronal cell death by low-energy low-frequency pulsed electromagnetic fields (PEMFs) (Gessi et al, 2019); increased bone density, faster recovery, increased formation of new bone, a further opening of the mouth and decreased pain depending on the post-operative PEMF treatment with 1 mT intensity and 40 Hz frequency in mandibular bone fractures (Mohajerani et al, 2019); and the improvement of pain intensity, disability and lumbar range of motion in PEMF exposure with 20 Gauss low intensity, 50 Hz frequency in patients with non-chronic specific low back pain (Elshiwi et al, 2019).…”
