The Stability

A pulsed electromagnetic field (PEMF) has been shown to contribute to heightening bone regeneration in a range of clinical areas, including dentistry. Due to the scarcity of studies using PEMF in oral implantology, the present experiment scrutinized the effect of PEMF can lead to improving the stability of the implant. A total of 19 subjects (40 implants in total) were selected to participate in the current study and were randomly allocated to either the PEMF group or control group. Subjects in the PEMF group received an activated miniaturized electromagnetic device (MED) while the control group received a sham healing cup. Implants stability was assessed by resonance frequency analyses (RFA) via implant stability quotient (ISQ) calculations. RFA were recorded as following: immediately after procedure, and then 2, 4, 6, 8 and 12 weeks later. Radiographic analysis was performed at baseline, 6 and 12 weeks after implant placement. Proinflammatory cytokines were evaluated in peri-implant crevicular fluid (PICF). The PEMF group presented higher ISQ mean values when compared to the control group. The primary stability time frame (the first 2 weeks) MED group depicted an increase in stability of 6.8%, compared to a decrease of 7.6% in the control group related to the baseline. An overall stability increase of 13% was found in MED treated group (p = 0.02), in contrast, the overall stability in the control group decreased by 2% (p = 0.008). TNF-α concentration during first 4 weeks was lower in the MED treated group. The data strongly suggests that MED generated continuing a PEMF may be considered as a new way to stimulate the stability of the implants at the early healing period.

Introduction. Although Colles? fracture i.e. a dorsally displaced distal radius fracture (DRF) is one of the most common fractures, there is no enough evidence to determine the best form of rehabilitation. Objective. To assess whether the use of pulsed electromagnetic field (PEMF) therapy during cast immobilization of DRF provides beneficial effects on pain, edema, wrist range of motion and function, as well as on the frequency of complications immediately after cast removal. Methods. The prospective randomized controlled study included 60 women over the age of 55 years with extra-articular displaced DRF treated with reduction and cast immobilization. The patients were alternately allocated to either a PEMF group (n=30, received 10 days of PEMF therapy during immobilization), or a control group (n=30, without PEMF therapy). Pain, function, hand circumference, wrist and forearm range of motion and frequency of complications for each patient was evaluated within two to three days of cast removal. Results. Better mean values for the majority of examined parameters were recorded in the PEMF group than in the control group, but the difference was statistically significant just for edema (p<0.001), flexion, extension and supination range (p<0.01). Conclusion. During immobilization PEMF therapy in DRF patients gave better results immediately after cast removal in terms of edema and wrist range of motion (ROM).

Currently, many children undergo precocious puberty, resulting in short stature due to premature closure of the growth plate. Pulsed electromagnetic field (PEMF) stimulation induces cell proliferation of articular chondrocytes. We developed a method for growth promotion using equipment with PEMF. In this study, we aimed to evaluate the effects of PEMF on the growth rate of growth plates using an animal model. An experimental study was conducted on 16 3-week-old rats to validate the effects of the growth care device on growth and development by PEMF stimulation at 28 Hz and 20 Gauss. The tibia bones of the groups with and without PEMF administration were dissected after 10 days, and then, the length of the growth plate of the knee and levels of insulin-like growth factor (IGF)-1 hormone in serum were measured. The length of the growth plate on the tibia bone and the levels of circulating IGF-1 were significantly increased by 25.6% and 13.6%, respectively, in the experimental group to which PEMF was applied compared to those of the control group, without any side effects. These results suggest that PEMF can safely stimulate growth of the growth plate in a non-invasive manner to promote bone growth.

Background. Postoperative pain, dysfunction, and significant bone loss may occur after vertebral fractures, which will lead to the occurrence of refractures and shorten the survival time, so postoperative rehabilitation is very important. Pulsed electromagnetic field therapy is noninvasive, pain-relieving, and beneficial to reduce bone loss and is an important treatment for patients to recover after surgery. Therefore, this study analyzed the effect of postmenopausal women’s vertebral fracture rehabilitation after pulsed electromagnetic field treatment. Method. This study uses a randomized controlled study, respectively, in the pulsed electromagnetic field treatment group (40 cases) and the control group (42 cases), respectively. We studied the results of health-related quality of life scores (HRQOL), back pain, body function, hip bone density, bone microstructure of tibia, and radius after 1 month and 3 months after surgery. Results. Compared with the control group, the pulsed electromagnetic field treatment group (PEMF) can improve significantly the psychological score, 6-minute walk test, and Chair Sit-and-Reach one month after the operation. And at 3 months after surgery, the pulsed electromagnetic field treatment group can improve significantly in health-related quality of life scores (HRQOL), back pain, and body function. Regarding the effect of changes in bone mass, compared with the control group, pulsed electromagnetic field treatment had no significant effect on changes in hip bone density. As a result of changes in bone microstructure, pulsed electromagnetic field treatment can significantly improve the bone microstructure of the radius and tibia three months after vertebral fractures. Conclusion. Pulsed electromagnetic field therapy has positive significance for improving pain, body functional changes, and bone loss after vertebral fracture surgery.

To assess whether pulsed electromagnetic field therapy during cast immobilization of distal radius fractures has beneficial effects on pain and limb function, the study included 52 patients (mean age 60.8 ± 15.0 years) with distal radius fractures treated with cast immobilization. Patients were allocated to a pulsed electromagnetic field group (n = 27) or a control group (n = 25). Pain; forearm and arm circumference; range of motion; disabilities of the arm, shoulder, and hand score; and touch sensation were evaluated on the day of the plaster cast dressing and 3 and 6 weeks after. In comparison to the control group, the pulsed electromagnetic field group reported significant changes after 3 and 6 weeks of treatment: lower pain levels (p=0.0052; p<0.0001, respectively), greater mobility of upper-limb joints, improvement in exteroceptive sensation, and reduction in disability of the upper limb (disabilities of the arm, shoulder, and hand) (p=0.0003; p<0.0001, respectively). Our results suggest that early addition of pulsed electromagnetic field treatment, during cast immobilization of distal radius fractures, has beneficial effects on the pain, exteroceptive sensation, range of motion, and daily functioning of patients.

Effects of pulsed electromagnetic field (PEMF) on hematology and hematopoiesis might vary with different PEMF parameters. The purpose of this study was to evaluate the possible effects of PEMF exposure at different pulses on hematologic and hematopoietic parameters in mice. Groups of male BALB/c mice were whole body exposed or were sham exposed (control) to PEMF at 100, 1000, and 10000 pulses. After PEMF exposure, blood samples and bone marrow cells of mice were collected for hematologic examinations, bone marrow nucleated cell counting, colony-forming units of granulocyte-macrophage (CFU-GM) colony assay, and serum granulocyte-macrophage colony-stimulating factor (GM-CSF) assay. Compared with the control group, white blood cells (WBC) and lymphocytes (LYM) in the 100 and 1000 pulses exposed groups were significantly increased but not changed in the 10000 pulses exposed group. Red blood cells (RBC), hemoglobin (HGB), and platelets (PLT) were not changed in all exposed groups. There was no significant difference in mouse bone marrow nucleated cell number between the control group and each exposed group 7 days after PEMF exposure. The CFU-GM clone number of bone marrow cells and serum GM-CSF level were significantly increased in the 100 and 1000 pulses exposed group but not changed in the 10000 pulses exposed group. Our results indicated that the PEMF exposure at fewer pulses may induce statistically significant alterations in some hematologic and hematopoietic parameters of mice but no changes can be found in the more pulses PEMF-exposed groups.
